blueprint

[cold lion]

so what should I do here?

[frosty heron]

Also triggered runs every frame

well a lot of think are misunderstood it seems

you want to use started instead of triggered

As to flip a boolean value, you can get the bool, drag and type not and set it

that will flip the value

[cold lion]

So like this?

[frosty heron]

that doesn't flip the value tho

I don't know what you want to do

this is how you flip a boolean value

[cold lion]

thanks

[frosty heron]

@cold lion you can simplify it with a select node

[cold lion]

One of these?

I am trying to have the sprint/Running be toggleable

[frosty heron]

well not how I would do it but I guess this is one of the way

[cold lion]

Thank you

haha I feel stupid lol

[dim halo]

The ai seems to be repeatedly tracking the target as if I’m running it through event tick

[rugged wigeon]

It doesn’t forget the focus you set. If it’s an actor that actor will remain the focus until cleared.

If you’re saying you tried clearing it and it didn’t help then you’re probably setting it on tick or in the BT repeatedly by mistake

[dim halo]

I see

So I would clear the focus momentarily to “pause” it?

[lethal coral]

Ok my character keeps zipping around the place like sonic the hedgehog and I can't figure out why

[graceful sage]

More specific?

Are the legs stuck to ground?

[lethal coral]

@graceful sage I've replaced the third person character with mine and made a blueprint so I could move around, but when I move my character she moves so fast she goes off screen then reappears when I stop moving.

[graceful sage]

Is the moving code the same?

I'd guess to check collision on mesh and capsule

[lethal coral]

this is what it's doing

[graceful sage]

Can't exactly tell from screenshot but show your code?

[lethal coral]

This is a video of my problem

[graceful sage]

I'd thr animations using root motion?

[lethal coral]

I think so how do I check?

[graceful sage]

Open the animations and look at root motion section

Based on video I'm pretty sure that's it

[lethal coral]

ok what do I need to do here?

[graceful sage]

If it's the starter animation then not using root motion

[lethal coral]

@graceful sage ok so what do I check if it's not the starter animations?

[graceful sage]

What's your movement code

[odd kiln]

Hi all ! Can anyone help me with my Fluid Simulation by Render Target in Blueprint please ? I already made it but it only works for 1 Actor. And I read that : If you want to simulate > 2 actors overlaping, you should make an array of components and location of there components that are overlaping, foreachloop and draw those to render target.

But I don't know how exactly to do this. I tried some things but it did not work at all :/

Also I don't know why some of my Actors (even if they are alone on the Surface) don't make the Fluid Simulation working

Here is the link https://forums.unrealengine.com/t/infinite-fluid-simulation-by-render-target-blueprint-tutorial/128540/1

[lusty hedge]

when on fire, the AI runs away. but in this case. its getting jammed and stuck on the player and as a result cant move

they also occasionally get stuck in walls

not sure what to do about it

[rugged wigeon]

You could also tell the actor to stop orienting to the focus

[faint forge]

I am trying to make an Editor Utility Widget that allows me to spawn or delete actors from in the level map, selecting them from Content Browser. "Get All Actors of Class" only accept Actor, my class is was made from Actor blueprint class, why I cant?

[frosty heron]

Read the error

[rugged wigeon]

Cast the class to actor class

[faint forge]

yes is like from the first node only gives an Object class

what would be the workaround?

[rugged wigeon]

The code here only "knows" that it's a subclass of object. You need to make sure it's explicitly defined as a subclass as actor

[frosty heron]

You are trying to get a class of an object type but trying to plug it to an actor class type

Object is not actor

[rugged wigeon]

Cast the class to actor class

[faint forge]

I tried it already, but I will try agian in case I missed sth

[rugged wigeon]

show your attempt

[faint forge]

first attemp

no luck

the display name is not printed (I am checkin in the OutputLog), only the 2nd print "printed?"

I will use a normal Cast node now, already tried too

cast fails

printing display name here correctly print the name of the bp class

is printing "BA_Grid"

[frosty heron]

a BP class is a UBlueprint

it's neither an object or actor if I am not mistaken

casting them as actor make little sense here, what are you trying to do?

[rugged wigeon]

it says parent class actor in the tooltip there

[faint forge]

yes

[frosty heron]

yes but the Asset is not an actor or object it's UBlueprint

[faint forge]

I need to select this BA_Grid blueprint and somehow get all actor of that class in the editor

[frosty heron]

the instance would be the type that is derived from

but the asset it self is not actor

[rugged wigeon]

nifty

[faint forge]

is there a way?

[frosty heron]

don't know in bp

but deffinitly there is a way in cpp, I haven't touch it yet tho, just saw some attempt by people in blueprint

it's kinda futile soo far as far as I see

you can access stuff like Material Instance, but a blueprint class like this, I am not sure

[faint forge]

ok thx

@frosty heron EditorActorSubsystem

[radiant wren]

Hey I was wondering if any of you guys knew how to basically say "hey, I don't care what your current rotation is, but go back to 0 after 2 seconds"

I figured it'd be a timeline with a lerp taking current local rotation in A and just 0 being B, and then feed that into a set local rotation, but both the set and get local rotations are a delta rotation which sets the speed of the rotation, no? Not actively says "hey, be this specific rotation" right?

[frosty heron]

@faint forge ask Authaer

[frosty heron]

anyway in blueprint?

[frosty heron]

show your code

[faint forge]

ok I did it! this is the solution

[radiant wren]

it's not much atm:

[frosty heron]

cache your current rotation before the time line
then in your timeline A is the cached rotation, B is 0

[maiden wadi]

Oh you meant the blueprints, yeah

[radiant wren]

well yes, but idk which node gets the active current rotation over just a delta

[frosty heron]

I see, never medle iwth this

[radiant wren]

like I want a node to tell me "where are you at" rather than "how fast are you going"

[frosty heron]

If the rotation are allowed to change during the timeline then don't use timeline

lerp on tick instead

RInterp current rotation to 0

[radiant wren]

hold on maybe I should better explain, give me a min to put something together...

[frosty heron]

Not sure why you would opt for interface here

[radiant wren]

oh cause I plan for more "click and drag" controls

[frosty heron]

anyway I would just Interp to 0 on Tick

using RInterp to or FInterp

That can be driven using a boolean

When you are dragging, obviously disable it but when you are no longer dragging, set it back to true

[radiant wren]

oh yeah so see the thing right before the timeline? that fires as soon as I let go of LMB

but then my issue remains the same: how do I get current local rotation?

and how do I set it?

that's all I really need, those two nodes

[frosty heron]

Turn Table Controller -> Get Rotation

that's your local rotation

[radiant wren]

but it's a delta rotation, no?

[frosty heron]

Not sure what delta rotation

It's relative to the parent yea

hence local rotation

[radiant wren]

oooohhh I figured out where I went wrong, I thought the light purple meant "delta rotation" but it just means anything involving rotation

[eager thicket]

is there a blueprint that determines whether a value is almost equal to 0?

so 0.1 and -0.1 will also register

[frosty heron]

delta means the difference afaik

i failed math but I'm pretty sure it just mean the difference between 2 rotation

[trim matrix]

Anyone? Its seems really easy with sequencer but not in anim bp/control rig

[radiant wren]

I always heard it was the rate of change, I.E. speed

[frosty heron]

@radiant wren

the basic idea from what I think you are trying to do

When not dragging, it just slowly rotate to 0

[radiant wren]

alright, thx, I think I see

[frosty heron]

near equal, adjust the tolerance as needed

[faint forge]

I am having this problem with a Spline, lets say I drag my mouse to the right... then the spline make an opposite "bouncing" before going to right if I am trying to create the spline very far away

in the video I use command Show Splines, and I am spawning along the spline some meshes but that shouldnt be a problem with the spline

I think has to be something with tangents?

[faint forge]

Solution: in case somebody need it, when I am updating the spline point positions, I fixed setting all the Spline point to Linear

[eager thicket]

so if im understanding the error tolerance, an ET of 0.1 means it's within 0.1 to -0.1?

thanks for the suggestion btw

[frosty heron]

it should be, I never use it my self

test it out

[eager thicket]

ok

[frosty heron]

float isn't really precise

maybe try 0.11

[spark steppe]

there's always https://www.h-schmidt.net/FloatConverter/IEEE754.html

to check what actual value it would represent

[wispy cedar]

Question : What is the purpose of Add Array if you can simply edit your index anytime ?

[dawn gazelle]

Add adds the entry to the end of the array, increasing the total number of indices.

[wispy cedar]

but my code is displaying GameMaker overdding Cry Engine string

i was thinking it defeats the whole purpose of Add

[dawn gazelle]

That's because index 3 is "GameMaker" by default. If you wanted to see "Cry Engine" you'd need to access Index 4.

[wispy cedar]

OH Thank you good sir

makes sense

Could anyone help me add a delay/cooldown to my blueprint? Im trying to make it so the collision capsule has a cooldown

[lunar sleet]

#rules #instructions

[lethal coral]

ok so what do I check/uncheck and what do I put in the drop down menu?

[lethal coral]

Where do I find that?

[lusty hedge]

rather than sett

how do i get a trace to ignore something of type

[lunar sleet]

You can trace for specific objects

[lusty hedge]

yes but this parameter is required before the trace

[lunar sleet]

There’s an object type enum on that node iirc

[radiant wren]

So I've got this section of code based off of the code from this video, and the link will jump to the point of the video in question but what he does to limit how far (in his case a door) can be dragged is as he shows in the video (idk how to explain it otherwise XD) but I don't like the way the door kinda "snaps" back into place when you try to drag it out of bounds, anyone know an alternate method of doing this that simply stops it from rotating but not stops you from ever rotating it at all ever? Just a simple "ah you can go the other direction but this is as far as you can go in this direction"

[rare gale]

Reference Viewer says I have 5 assets referencing a BP, I've scrubbed through those assets and can't find any references to it. What am I missing? No variables, no interface calls, no function inputs/outputs. How else would something reference it?

[lunar sleet]

Prly better to move this post to #multiplayer

[radiant wren]

if you're sure you've scrubbed all references you can force delete, at least that's what I do

[lunar sleet]

Update redirectors too

I've updated redirectors. I'm at the point where I'm ready to roll the dice and delete, just wondered if there was somewhere obvious I hadn't thought to look. Thanks all

[loud tree]

If I'm understanding correctly a simple method for this could be to:

Add a do once node at the beginning of the code. Set timer by event at the end of the code. Connect that to a custom event to reset the do once.

[pliant marten]

not sure if this is the right place for this but im having alot of trouble with a UI widget. Im setting an image from a material instance dynamic for a simple compass. Everything works on the material properly but the widget is creating 2 images , 1 static of this original image and one that properly moves from the instance. I have tried everything i can to figure this out. i would really appreciate some help or if someone has run into this issue. I attached a clip so you can see what happening.

[loud tree]

Have you tried clearing the image itself to be blank and running it?

[pliant marten]

yea i also tried setting a fully transparent image the same size. empty its a white box,

[loud tree]

To me it looks like the static image is the image you have set, then you're generating the material that moves over it

[pliant marten]

same resuly

result*

[pliant marten]

im setting the image to a material

[lusty hedge]

how do i make the trace ignore everthing except 1 thing

[pliant marten]

modify the collision respone on the traces default from block to ignore and set the collsion response on that one object to block

delete the make array and inputs

[lunar sleet]

or you know, use the other line trace, like I told you

either works

[lusty hedge]

i didnt understand what you were saying before. thank you

A little turret witha status light i made

[slender grail]

Hello, not sure if that's the right channel to post this question in.

I was trying to follow this video (https://www.youtube.com/watch?v=oYmfq1GJaMQ) to make spline meshes with Blueprints, however I've been experiencing major FPS drops when I'm modifying an actor that has a spline component (the spline component is the only component!). The device I run UE on is pretty powerful so I was thinking something else might cause the issue.

By the way, my end goal is to dynamically update the spline shape during runtime, and with it, update the mesh

Any advice regarding my problem would be appreciated :)

[marble tusk]

I want to say it's related to having the spline directly selected in the component list, but I'm not 100% positive on that. I think in 5.4 they changed the default behavior to automatically select the component when you edit the visualizer which is really dumb imo. Luckily, there's a cvsr to change it back which I need to lookup because I don't remember it

#ue5-general message

So try Editor.ComponentVisualizer.AutoSelectComponent false and see if that fixes it I guess

[slender grail]

That worked perfectly, thank you so much. I didn't even know about this line

[raven gyro]

can any one help me with this print?

i follow tutotiral but no work D:

[lunar sleet]

You need to call the event if you want it to print

[raven gyro]

this is my call here

[dawn gazelle]

If the widget you're attempting to bind to is created by the "Interactive Anatomy Main Screen" widget, it may not exist yet by the time you're trying to call the Get All Widgets of Class.

[raven gyro]

the widget im attempting to bind is created by the "Anatomy Menu"

[idle sandal]

hi, i am having a problem with accessing a variable in a widget using interfaces. when i try to access the text block variable with a regular event the text block exists, but if i try and access the text block through the interface function, it gives me a null reference. does anybody have any ideas of what i might be doing wrong? or maybe something i can look into with using interfaces with widgets? the first 2 images is just printing the name and it working, the second 2 are me trying the same thing with a interface and getting a null reference. for some context, i have a slot widget that calls the interface function when a slot is clicked, which then is supposed to update some text. \

[maiden wadi]

Show where you're calling this.

[idle sandal]

this is on my slot widget

if i just use print the information from the slot that i want it gives me what i need, but as soon as i try editing the text block with that info i get the null reference on the text block

[maiden wadi]

That's a bit odd. Should work fine.

[idle sandal]

thats what they said in the umg channel but i just dont get what could be wrong, and if i try and make a new project with just the slot and inventory, whenever i set the reference to the main inventory and hit compile it crashes the entire editor so i just have no clue whats going on, im using the engine built from source so idk maybe somethings just bugged or

[maiden wadi]

TBF interfaces aren't used in UI very much. 🤷‍♂️ I mean what you are doing 'should' work. But it's more common for children to use delegates when something happens. Same idea as a button being clicked. And containerparents of them can bind their events and directly call functions on their children, but children rarely care about the parent. And if you are in the parent, you don't really need an interface most times vs just simply calling a direct function.

[idle sandal]

i just stepped away for a few minutes, but when i get back ill try it again, but iirc i tried originally with a event dispatcher as well as a event to just update the text and i was getting the same problem, is it possible im just setting up my slot incorrectly?

[maiden wadi]

I'm unsure. Your bug doesn't really make sense to me. Because if the textblock prints correctly at OnInit, but not after a button click... Only thing I got from that is that it was deleted somehow? OnInit will run at the CreateWidget time. So it's super early in the creation process. Long before anything like Construct. Your button click clearly has a valid widget to call the function on, so it has to have been created and therefore ran Init.

hello 🙂 so I just followed this video https://youtu.be/2GKC8yEgv2s?si=qbTxuL1gyij-rLWA on "How to Play a Video In-Game in Unreal Engine 5". But somehow it does not work for me.

Hey all, got a question about collisions when simulating physics on skeletal meshes.

• In the first image the actor calls "Set All Bodies Below Sim Physics". The box trace does not hit.
• any traces that hit parts of the skeletal mesh inside the capsule component however do hit.
• In the second image I do **not **call the sim physics node and the box trace hits, regardless of the mesh being inside the capsule or not

Could anyone explain why traces do not hit on skeletal meshes outside the character capsule component when simulating physics? And is there a workaround for this? Thank you in advance 🫡

The game has fall damage, im just tryna make a platform on my map that cancels that out

Is there a way to use a exec to set a boonlean to true/false?

[maiden wadi]

What's a boonlean?

[rare violet]

i meant boolean

thought it had a n

[dawn gazelle]

In your fall damage logic, have it check if a "NoFallDamage" tag is present on your player and if so, don't apply fall damage. Give the platform an overlap collider that applies the tag on overlap and removes it on end overlap.

[civic granite]

does anyone know how to properly set up widget in network play? I would like to set it up in BeginPlay of Player Controller but the widget doesn't show up when I play the level in PIE with "Play as Client" net mode

[maiden wadi]

It should. But you should also use the AHUD class. One is created per player, per machine. Meaning never on a dedicated server and you don't have to do gates like IsLocallyControlled.

[civic granite]

Thanks. I tried but it still doesn't work. I created a new blueprint "TestHUD" inherited from AHUD class, configured the blueprint logic like in the screenshot, and set HUD class in gamemode to the new HUD blueprint. it does work in standalone gameplay but somehow not in networked gameplay. Do I still need to add something to the blueprint logic?

[rare violet]

(fixed it)

[crude tartan]

Hey All - If I want to use a soft object reference in the Construction Script can I just use a resolve node to convert my soft object to a hard object ref? Load Async isn't available in Construction Script (assume it doesn't work with the editor).

[deft badge]

Okay so I have a character that walks into a room. I want the character to automatically walk to the other end of the room when he enters.
I hit a trigger box, disable controller input and use add movement input set to make the character do that. It works excellent, besides when I simulate or package as shipping build. The add move input seems to not do anything then. Anyone have any ideas.

[dawn gazelle]

Have you tried restarting the editor? Creating a widget on begin play of either AHUD or PlayerController should work just fine regardless of whether it's Run As Client or Standalone.

The only instance I can think of where it may not work correctly is if Begin Play itself doesn't fire which can happen if you have a mismatching GameMode and GameState (ie. using GameModeBase but using GameState as your GameState's class) but this would prevent Begin Play from firing on both Run as Client and Standalone.

[civic granite]

Thanks for the advice. I finally find out the root cause. Actually i was using AnimatedMannyPawn blueprint from MoverExamples plugin and that pawn was removing all widget when a game is started. I avoided the "Remove All Widgets" node in the blueprint and it worked now.

[unique nacelle]

Hiya 👋 I am trying to make an anti-gravity field box. See here in the first-person template I added a BP_GravityField which extends the Field System actor. The red box is two things occupying the space space, 1. a cube with a semi-transparent red material and all its collision/physics turned off, to visualize the field, and 2. a box collision. When I run this level, all the blue crates go flying up and away forever. It's the effect I want but it's not being culled to the box collision. In my blueprint event graph, when I change the culling field culling operation to Inside, then none of the blue crates are affected.

[mild jacinth]

when it comes to LAN and ?listen server how can i get the client instance's player controller instead of getting index?

assuming i wont be using steam networking

this targets only server becuse server is host and has pc index 0

[dawn gazelle]

You can't really think in terms of "client's instance". You need to think in terms of how does this current blueprint have a relation to the player controller of the client you're wanting to utilize.

Eg. If this is in the controlled pawn of that client, then you can get the controller of that pawn. If this blueprint is a child of Hud or PlayerState, they both have a means of getting the owning player controller.

[mild jacinth]

it is a game instance bp

[dawn gazelle]

So unfortunately, that has no relationship to any playercontroller, so there's no good way to reference the playercontroller directly.

Alternatively you could have the player controller or one of the classes I mentioned above make a function call to the game instance and pass along a reference to itself so that you can get the player controller.

[mild jacinth]

even if its done inside player bp i fail to see how you can get the index automaaticlly and retun pc

unless you mean this

[frosty heron]

well mainly because you don't really want to use index

[frosty heron]

This is what you will mainly use

[mild jacinth]

i mean i dont yeh. it opens wrong widget which is server at index 0

client is at index 1

[frosty heron]

the index is never guaranteed

and how you will know who's who?

the general advice is to not use get Player controller with index

It's easy to know which controller owns the actor. Just use get Controller

https://wizardcell.com/unreal/multiplayer-tips-and-tricks/

have a read through this

[dawn gazelle]

Widgets are always local.

So if you create and add it when running on the server, the server is the one that's going to create it and add it to their screen.

[frosty heron]

@dawn gazelle I'm trying to figure out how to do random idle animation in multiplayer, do you have any pointer.

thingking that maybe I could use the network clock as the seed

but maybe there is a simpler way?

[dawn gazelle]

Probably just a GameplayTag or Enumerator or something that you set randomly when the player has been idle for long enoguh?

[mild jacinth]

wouldnt multicast take care of this>?

[frosty heron]

that makes no sense 😄

[mild jacinth]

i mean how can you add the widget to the client screen

inside gameinstnce

[frosty heron]

I'm thingking I don't need constant RPC or anything. I just need the clients to agree with the server on same seed, then each machine can simulate their own

[frosty heron]

doesn't sound like the right place tbh

[rare dirge]

Actor stops moving in forward direction after 30 sec camera keeps rotating in all degrees. Help

[frosty heron]

you can just do a client RPC in more reasonable place

[mild jacinth]

question

why is it that using print string yields such messages? (i set the text, but i mean that "Server" part. if I use client then it says Client 0:

why are these debug print string messages replicated?

[dawn gazelle]

They're not replicated. You're seeing on which instance of the game the print string is happening - makes it easier to understand where the print string is being triggered.

[mild jacinth]

ah ok

is game instance accessible on multiplayer unlike gamemode which cannot be accessed?

[frosty heron]

Every machine have their own game instance

and there's no way to reach someone else game instance other than your own

doesn't matter server or client

[lost hemlock]

@rose crest hi

[rose crest]

If you want to pass information or checks globally for all players use gamestate, it's replicated,but slow by default (1/s?) if you need information about specific player use players state. Game state is for server to run server side functions

[rose crest]

Hi

[mental trellis]

PS is also pretty slow by default.

If you want a player-based quick rep, use the player controller or their pawn. Or increase the net frequency of the other things.

[rose crest]

If it's low scope multi. Like few players then just increase net frequency

[frosty heron]

For more accurate timer, you will need to adjust with RTT imo

perhaps an RPC with RTT then let client decrement on it's own

that way you just need to ask for time once

[rose crest]

Or once every xx seconds to sync if you want to cheat proof it

[frosty heron]

Well it shouldn't matter since only the server time matters

client time is just there for visual

[mental trellis]

If you don't want to increase teh net frequency of the game state, you can always add another, specific actor.

For a timer, though, it really doesn't matter. You don't want to replicate the remaining time of a timer. You replicate the end time once and work out the time left on the client.

If you replicate the end time of a timer, it'll be in "server time". The game state has a "get server time" (or something similar) method which you should use to compare, rather than your local client time.

[limpid nebula]

Hi , anybody know how to pass parameters to a function that is called by a timer?

If I try passing calling function which has parameters by a timer , the function is not working.

[rose crest]

let function grab parameter during execution

Hi i am having problems with character movement

Basically my character moves fine, then i enter a car, unpossess the character, and possess the car (which also moves fine). I then exit the car, and repossess the character. Now the character no longer can run/walk or jump but for some reason my punch and dodge inputs still work.

Has anyone seen something like this before? I checked if it is still attached to that car (it was not), I checked whether inputs were being ignored (also no), so not sure what to do.

Thank you!

[mental trellis]

Did you deactivate teh movement component and not reactivate it? Or something?

Can someone help me with how to add sound variable in the widgets graph
Basically what i want is that when i click on a button the sound stops playing

These are the blueprints

That is used

[kind willow]

And what about this isn't working?

[cunning juniper]

The sound is not stoping

The sound is of half a minuite so it plays for half a minuite and then stops

[kind willow]

Can you add a breakpoint to the stop node to make sure it triggers?

[crude dew]

Hi can someone please tell me why when i use Set World Location in the X channels it does nothing but using the same wires into the Y it works fine ?

This is what the mapping for that control event looks like

[kind willow]

Are you sure the X axis movement triggers? Also, do you really need 2 set world location nodes for this? I feel liek you could do it in a single one, although I'm not sure

[crude dew]

V you might be right i didnt think to use one set world location tbh ... XD but i tried to print string the X and it printsout 0.0

[kind willow]

It prints out 0 directly from the event?

[cunning juniper]

No i cannot add a break point as the skip button is suppose to remove the widget

[crude dew]

Printing the X shows 0.0

[kind willow]

Then it's gotta be your input settings somehow. Make sure the buttons are bound to actions and that your axises are facing the right way

[kind willow]

Yeah, I have no idea what you are trying to achieve mate, sorry

[crude dew]

Yes for some reason the Y does print -1 / +1

but X 0.0 not sure why though

[cunning juniper]

Ok no problem

[crude dew]

i thought the mappings looked fine

[kind willow]

As I said, it should print out a value as long as there's input. If there's not value, there's no input. You have to make sure it's set correctly

[versed sun]

I dont think you want to swizzle all for

[crude dew]

Ahh im not too used to the enhanced input so not sure what i would need to use, Any help is appreciated thanks 🙂

I used Vectior2D which i think is correct for X and Y movement

i thought the swizzle would send either -1 or +1 as values.

I kind of think of it like a virtual joystick for values

[kind willow]

I don't know much about it either, but I'll check how my project has it set up

[crude dew]

im not using a Character as my player is a cube which just moves around with inputs so i have no Character movement component for Add Movement Input

[kind willow]

It should still use the same input though, no?

[crude dew]

I would have thought so but not sure.

Not sure why Y is sending values but X is sending nothing makes no sense.

[kind willow]

Huh, tbh I have no idea why is mine working either...

[crude dew]

ye very odd.

You can see I press all the buttons W,S,A,D and X never changes from 0.0 but Y does.

Your D has no swizzle axis I assume D is back

so maybe dont need it for Forwards and Back

[kind willow]

D moves right, I think it's positive X axis

[crude dew]

Ohh ok seems like for me I didnt need the Swizzle Axis in W,S

as X is now sending values, Thank you for your help!

bit weird but works xD will have to remember it lkol

[kind willow]

Glad I could stumble around with you until we found a solution, lol

Hello everyone, i'm very new to UE. I've been Following Reid's InventoryGridSystem wich ends up with a "event actorbeginoverlap" as a pickupsystem, i'd like to change that to work with a bind and a linetrace but here is my issue : when i setup a lanetrace like i usually do, i can't get it to recognize the item. (On my other project the same system works, but here it doesn't). During the tutorial, Reid make us add a Gamestate, would the issue come from this ? Might anyone please help me debug this situation 🙏

[radiant wren]

ah....

[devout egret]

Are the collisions on the pickup and trace set to block

[grave relic]

Without SDK or login. I know someone who just uses "Player State" and "Get Player Name" to retrieve the Steam account name.
It has a game and a leaderboard, it doesn't use anything other than what I said above. It's possible or not because I have another guy who tells me no so I don't understand...

Hi. I am controlling a ball's movement using the "add impulse" node but it moves different distances each time. I have a constant target location and dynamically calculate the starting location. However, the ball doesn't move the expected distance, even with a static starting location for tests.
Is the "add impulse" node FPS dependent? How can I accurately control the ball's movement?

[dawn gazelle]

Without the Steam SDK you wouldn't be able to retrieve data from Steam at all.

[steel crag]

As you can see here they aren't i use a sphere collision, to be honest i don't know how to set the trace to block, but as i said when i do the same system on a new project i have no probleme it goes recognised. (BPC_ITEM is my parent class for all pickable Item)

[devout egret]

collision would be in here

youre using visibility trace

[steel crag]

Hey, first of all, thanks for helping out ! indid i use visibility for now, is that a problem ?

[devout egret]

open the collision preset, is visibility blocked?

[devout egret]

might be because its overlap, im not exactly sure, I dont know the most about collision but try making the collision preset custom and then making visibility blocked

let me know if that works

[steel crag]

It does ! Damn you saved me right now, it's been hours of TS hahahah

what print? show more code if oyu have

you might be overwriting the same Material 3 times , and returning the last one(2)

[raven gyro]

for that return value they both print out dynaminc material instance_0

[maiden wadi]

You might want to double check what this person said. Because you 100% need to be using the Steam subsystems and stuff and have it all enabled in the inis. The login happens automatically if you set up your inis correct, and the engine ships with the sdk. If they are using GetPlayerName and getting the user's Steam name, they're using Steam. As Datura said, you cannot access Steam's API to even retrieve the user name, let alone pass leaderboard info and such without the SDK.

[devout egret]

where is the print statement

[raven gyro]

all of them print out like that

i have like 20 objects i want to fade away, but making like 20 dynaminc instances is just too much QQ

Hiii. anyone help please 🥺

I´m trying to make an interaction with an object, I´ve already made that if the linetrace hits the interatable object the UI appears saying "Mouse Left button to interact" , but now I don´t know which nodes can I use to say that if the UI appears, and they clic the MLB, go to interact.

I think this should be fairly easy but I can´t seem to find what is missing there I can´t add an event there can I?

[steel crag]

The best would be to make a function that start an event that would be usable on all actor right ? If that's so i'm looking for the same thing :).

[rare inlet]

well right now if I connect the top add to viewport with the Interact node, when I have an interactable object and I hover over it it will interact it works but I need it to ONLY interact if I press the LMB over an interactable object

[steel crag]

May you show me your interact function ? I'm not gonna help you, but you will help me 😂

Interact input event -> gate -> interact interface event. You can open and close the gate depending on what your line trace returns.

[dawn gazelle]

When you do your line trace and find an interactable actor, promote that actor to a variable like "Interactable Actor". When you don't find an interactable actor, set it to nothing.
On your mouse click event, you can now call your interact event and feed in the "interactable Actor" variable.

[frail onyx]

Anyone know how i would go about trying to add a homing missile like this into my game? https://www.youtube.com/watch?v=Z6qBeuN-H1M My end goal would be have a point that spawns a new rocket every like 20 seconds or so, and then the rocket that is spawned homes toward the player that is moving, but its possible to dodge it in time if you dodge out of the way fast in front of a wall so the missile will hit the wall and blowup since it wont have enough time to turn. Kinda like this type of rocket from dani's vid at 6:10 https://www.youtube.com/watch?v=WU_V6vp9sAc&t=210s

[maiden wadi]

You make a new actor class with a ProjectileMovementComponent. When your thing that spawns it ever 20 seconds spawns it, you set the homing target as the player. After that it's just about tuning the homing parameters and stuff to make it turn the way you like. If the player dodges, it should try to turn but probably hit something while trying to.

[frail onyx]

Do you know what parameters I can change cause all I could find under the homing section was the acceleration force and the checkbox to make it a homing projectile

[frail onyx]

Would I achieve a more satisfying result if I use physics to fully do it?

[stark patio]

does anyone know how i could make this kind of camera rotation?
https://imgur.com/a/A72dxNC

I have tried changing the control rotation which works until i move left and try to look around, in that case it locks the camera to being horizontal for some reason.

(here is an image of the code, the float going in to it all is the players sideways input)

[rugged wigeon]

Put the camera on another actor whose sole job is to swivel like that

[dawn gazelle]

You wouldn't want to necessarily use control rotation for a visual thing like this, you probably just want to add some roll to your camera. Why it's getting stuck is beceause you're forcing your control rotation to be whatever your current control rotation is, so it prevents you from rotating your pitch and yaw.

[stark patio]

that would work but it feels like there should be a better way

[stark patio]

i see, but whenever i try to change the cameras roll or rotation in any other way it doesnt change

[uneven girder]

hey there ladys and gents, i have not looked into blueprints that much. i spent quite some time online trying to figure it out to no avail, so I ask you, how can i fix my cast? I am trying to create a simple level with a keycode door

both casts to the FirstPersonCharacter fail

[dawn gazelle]

You need to connect "Other Actor" to your cast.

Not Component.

[stark patio]

that is because first person character is not a component. You are currently dragging in "overlapped component"

[uneven girder]

oh, ok. thanks a lot

[dawn gazelle]

Try using this node instead.

[uneven girder]

works out for me, that was the fastest i have got an answer regarding an issue here, much love 😄

[stark patio]

nothing changes when i use it, the camera rotation stays the same :(

it does change if i turn of "use pawn controll rotation" but then a bunch of other stuff stops working

[silk cosmos]

That's probably because your camera is set to orient to your contorl rotation. Uncheck that setting on your camera and try attaching your camera to a spring arm that is set to orient to your control rotation.

[stark patio]

ah that did work

thank both of you guys :D

[stark patio]

[trim matrix]

how to get the camera rotation applied in an animation BP so that we are able to pass that number to a control rig.?

I dont get what you are trying to do, but you can easily communicate back and forth between anim bp and character bp, by using custom events.

Getaniminstance gives you the anim bp from character

Get owner gives you the character from anim bp

Can I extract audio from .uasset file with javascript?

Is there some reason AssetActions->Export is not what you want, why javascript?

[cold sorrel]

I want to create .uasset store web site

I can show thumbnail image of file

If file consist audio

I want to play it on web browser

how can i do it?

[stone field]

i think it might be simplest to ask uploaders of the uassets to include a heavily compressed sample in mp3 or something

[cold sorrel]

Thank for your helping. The issue is to extract from .uasset file

there isn't another solution?

[stone field]

well, you could theoretically have a server running unreal and code up something that does the extract to .wav, then encodes it to mp4, then adds it to your database

[cold sorrel]

Someone suggest me to use uasset-reader.js

[opal snow]

New to splines and I can't seem to get my actor to follow the path I created in the editor. Is something wrong with this logic? https://blueprintue.com/blueprint/ihb0lq4v/

[stone field]

Assuming you have visual studio : Rightclick the CallURL node and check the source that it is not some editor specific module or something?

If no clues there, I would add print strings around the area to verify urls and see if it returns anything

[stone field]

log out the Lerping values to see what's going on, are B and Alpha values what you expect?

[opal snow]

Not really sure what they're supposed to be because I don't know how to get the coordinates of each individual spline point I set up

but right now my actor just heads towards the first point and keeps going past it infinitely

doesn't follow the other points I set up

[thin panther]

editor only nodes can only be called in editor only actors, i.e. editor utility actors or editor utility widgets

[stone field]

I see, so shouldn't be possible to try to call it wrong ( as long as the node is declared correctly, not just code inside ifdeffed )

You can certainly manipulate bone transform in control rig. Look up IK foot implementation in default third person template.

[trim matrix]

Dw, the screenshots are just to understand but they aren't really important

[frosty heron]

I know buts it's annoying to see it

[trim matrix]

You can get the rotation but cant add the value (the quat)

[frosty heron]

Don't know what you are talking about.

You can set the bone transform, period. Look up an example that is already done in third person template.

Nothing to do with quat or w.e . Quat is just a data type to be used when rotating something and you don't want to be limited to gimbals lock.

[trim matrix]

What i want to do is kind of "add controller yaw input"/pitch but in the control rig so a bone rotates...

And not the entire mesh

[frosty heron]

What bone exactly? The head?

[trim matrix]

Yes

[frosty heron]

Look up some tutorial on head tracking

And you don't add anything you just set the bone to look at a specific point.

[trim matrix]

Maybe the node aim math

Ok thx

[trim matrix]

Look where? It ahould be added to the current bone rotation

And there's no video about that

[frosty heron]

#blueprint message

This is how I do my head tracking. Got the code from the internet too. If that doesn't help getting what you want, then I'm throwing my towel.

[trim matrix]

The head of the character doesnt track anything, it should just rotate depending on the mouse (2d vector)

Maybe its not possible bp only 🤷‍♂️

[frosty heron]

Totally possible in bp

Convert mouse location to screen space if it's a top down game

And that will be the point where your head look

Actually using world space will work too

[trim matrix]

Im using a 3rd person camera which is attached to the head socket and rotate with it...
I need to find a way to rotate the bone

[frosty heron]

Again, set bone transform in anim bp

Can't tell if you are just trolling or lazy at this point.

[trim matrix]

You cant change bones in an anim bp

[frosty heron]

You can rotate bone in anim bp or set its transform

I did it many times

[trim matrix]

Are you talking about the transform bone node?

I swear i never heard of it.. thx, i'll try to make it work!

[frosty heron]

Getsockettransform or something like that. To get your bone transform.

Socket name is your bone name

[final python]

is there any performance issues if you do very simple animations in code rather than making an animation?

like I am making a first person game and the character doesn't have a body, and I am keeping the style of the game stylized and simple, and so when they use a weapon I just wanna add rotation to it when you click

[versed sun]

once you get to a few hundred timelines running you might see some fps drops

[final python]

haha, so I take it as not too big of an issue for my project then

I am a long ways away from using that many to begin with, let alone having them all be running at the same time

[versed sun]

as long as you code responsibly

[final python]

yea for my plants growing I created a plant manager that just runs 1 timer and updates a few random plants, instead of having a timer for each plant. So I am already a bit cautious. I just wasn't sure if code based animation could be a catastrophe or not

Ain't as simple as plugging the pitch and yaw or w.e value you get that from...

These are valid and the mesh is rotating but it looks like something is blocking it

It jitters to his original position

[raw spindle]

is there no way to define a comparator to sort arbitrary objects in blueprint? 😦

[rugged wigeon]

Just make a function?

If you really need it to be a static concept then yes you need cpp

[rugged wigeon]

eh. It's kind of a pain.

The gist is that you're going to want to play a montage to trigger the animation to get in or out of the car. You're probably going to want to use "motion warping" to make sure the animation snaps into the right position while it's playing smoothly. You're going to have to think about how you're going to animate the car door opening too. Hope you have car mesh that isn't just one solid polygon.

But realistically that's going to be a lot of nitty gritty work for a level of polish that is probably beyond your understanding right now. You'd probably be better off just not animating getting into the car.

just make the guy disappear and magically start controlling the car like most games do

[bronze badge]

I used Motion Warping but the animation does not work.. i tried to enter the vehicle without animations and it works.. i was looking at this guy https://www.youtube.com/watch?v=uUi2Yz7JTM8&t=1765s&pp=ygUhZ2FtZSBhbmltYXRpb24gc2FtcGxlIGVudGVyIGV4aXQg but something is off and i don't really understand what bcs the BP_Interaction is not doing anything.. i will try to call the door and move it with the timeline and use motion warping for the anims.. if you are on a high level in unreal maybe if i can't do it this one more time, you can take a look and help me a little if you would be kind obv..

[bronze badge]

also i decided to work in the city sample with all the system they give for the car so im not actually using the city sample vehicle pack..

[cedar sparrow]

What is the point of the Save Game in structs? can you not save a struct in a SaveGame object without that?

[lunar sleet]

That checkbox is there for many things. It asks if you want it to be captured by the savegame object when saving

[cedar sparrow]

Automatically so I don't have to pass it to the SG object?

[primal zenith]

noob question, can i use a blank scene component as a folder within a blueprint actor's components? Will previous logic respect the associated objects i re-root under it? The top root object won't be changed, just child components

[lunar sleet]

Uh, you might need to turn some things on, I don’t rmbr.

[cedar sparrow]

Ah ok thanks. I'll take a look.

[frosty heron]

for CPP use, in context of serialization

[ruby tendon]

So I am trying to make it that if I move the mouse Y position like lets say 500 pixels, the arrow rotation goes from 0 to 90 degrees. I have no clue on how to make this work i also tried using the screen resolution which kinda worked, but it doesnt work when its windowed. Anyone know how to do this? (the video is a demonstration of what I want, but this doesnt work. If anyone can help me that would be amazing!

[dark drum]

It doesn't do anything unless you're using C++. It's a flag that you can use to get if the property should be serialized. It can be useful when you want to serialize an entire object ready to be saved.

In BP, any variable placed in a save game object will be serialized and saved to disc (when you call save game to slot) regardless of whether the flag is ticked or not.

[queen heron]

anyone got an idea about why the random float in range from stream gives the same vector output no matter the value which the Spline Side Location has?

this setup is set to offset the spawned actor along the right vector of the spline at the current distance

I'm using from stream to test a feature I've made for the player character

Random Point Along Spline is also randomized from stream, and it works just fine when I change the stream variable values, and its not the same stream variable

yet somehow, using the Seed Random Stream makes it work just fine

ah ok, I figured it out
I print stringed the random stream, and saw that I was getting a different stream seed

I actually thought that setting the random stream variable manually would work

but it looks like it works alot different than I expected

using the Set Random Stream Seed does the trick

Anyone has tried using the camera attached to a socket? Im having some problem

[devout tide]

Restarted the editor?

[trim matrix]

the problem is that node, which blocks and doesnt actually rotate anything

[brittle wind]

Okay I figured it out

What a pain in the ass, lemme double check some things and ill explain

[devout tide]

Well if your camera is attached to the head bone and the headbone is controlled by your animation blueprint, its absolutely normal this would happen. You need to ajdust your animation blueprint and logic to support what you are trying to do here

[devout tide]

^

But in any case, for the camera to be controllable by input you need to check Use Pawn Control Rotation on it

[trim matrix]

It actually work and rotate a bit, but then something blocks and it goes back to the original position and its jittering

[brittle wind]

If anyone else every wants to use primary data assets
First you Need to make a C++ base class, as none of this wil work in blueprints.

UCLASS()
//Use your games name_API, and name the class however. Mine is ItemPrimaryDataAsset
class STRANDED_API UItemPrimaryDataAsset : public UPrimaryDataAsset
{
    GENERATED_BODY()
    
public:
    
    FPrimaryAssetId GetPrimaryAssetId() const override{
//Write the name of your assets here, mine is Items
        return FPrimaryAssetId("Items", GetFName());
    }
};```

Now create your blueprint based off that class.
Next create a field in the asset manager with the name you used "Items" and whatever blueprint class you built off of it. Make sure to NOT check 'has blueprint classes'

And that's it. Done

[trim matrix]

Pretty sure the node is broken since i selected "add to existing" so the rotation should be added but it doesnt seems to work

you don't add, you set

you should knoww where your head is looking

set with interp

You dont, its the mouse that tells you

[trim matrix]

I feel like its impossible

[frosty heron]

head rotation is easy actually

just try to understand the math to begin with

it can be as simple as using Find look at rotation

[trim matrix]

it always jitters to its original position

Like the top of a tank should rotate but not the body..

[willow gate]

Is it still not possible to manually change the game mode at runtime? With my level load system, my loading level has a different game mode than my regular levels (because they require different pawns and functionality). This is causing irritating issues.

[trim matrix]

Search on google, theres many videos and docs

[rugged wigeon]

Levels have their own game modes.

if you load a level, you're going to load it with it's desired game mode

check world settings

[willow gate]

Right. I have the normal game mode set in my persistent level, which is the same game mode for most of the game play. But my playable loading level has a different game mode. So I can't actually load a level in the background while letting the player interact with the level unless they have the same game modes or I guess I have to override the default spawning behavior.

[willow gate]

I definitely did my due dilligence before approaching this forum. Thanks though.

[rugged wigeon]

Idk off the top of my head but it sounds pretty niche to have a "playable loading level" that is so substantial that it requires it's own game mode. Why is your game loading so much?

like, if it is that substantial, do you really need persistence from the main game? Can you just load the meshes and stuff and make those persistent?

[willow gate]

I set up a new game mode anticipating that I might need some custom stuff in the controller but really right now it just serves to spawn and possess two different pawns. So I think probably the answer here is just to override default spawning behavior to spawn the loading pawn and the regular pawn where desired.

[willow gate]

Yeah that may be a good option as well. Thanks. I have a better starting place to rework this.

Hey when I add this bit of code to my replay player controller it crashes when I try to record a replay, this is so so so odd to me.
Some logs: [2024.08.05-15.15.30:959][179]LogWindows: Error: === Critical error: === [2024.08.05-15.15.30:959][179]LogWindows: Error: [2024.08.05-15.15.30:959][179]LogWindows: Error: Fatal error: [File:E:\Epic Games\UnrealEngine-release\Engine\Source\Runtime\CoreUObject\Private\Templates\Casts.cpp] [Line: 10] [2024.08.05-15.15.30:959][179]LogWindows: Error: Cast of DemoNetConnection /Engine/Transient.DemoNetConnection_0 to LocalPlayer failed [2024.08.05-15.15.30:959][179]LogWindows: Error: [2024.08.05-15.15.30:959][179]LogWindows: Error: [2024.08.05-15.15.30:959][179]LogWindows: Error: [Callstack] 0x00007ffc2321aafe UnrealEditor-CoreUObject.dll!CastLogError() [E:\Epic Games\UnrealEngine-release\Engine\Source\Runtime\CoreUObject\Private\Templates\Casts.cpp:10] [2024.08.05-15.15.30:959][179]LogWindows: Error: [Callstack] 0x00007ffc1a308254 UnrealEditor-UMG.dll!UUserWidget::CreateWidgetInstance() [E:\Epic Games\UnrealEngine-release\Engine\Source\Runtime\UMG\Private\UserWidget.cpp:2401]

This can't be intended right? Why does it need this replay controller if it is used simply for the playback part, not the recording part????

am I missing something?

I see, I've read a bit on it and this controller is for recording?

nvm, it is only for playing the replay, this has me utterly confused as to how this could be a problem and why the replay player controller starts existing whenever I start to record a replay

I don't have SetViewerOverride set anywhere for the record

[bold plover]

i think you should check your spring arm settings, you might have camera lag turned on (assuming the lag behind the player is what you are talking about)

[trail root]

Sorry if i described it wrong, what i mean is my camera position is affecting my character move speed, when i had Get Control Rotation instead of Camera in my blueprint screenshot the speed of character was okay but movement (controls) was never adapting to changed camera position (check video). Now the problem is camera angle is affecting my character speed. Please let me know if you want me to better describe something, thanks.

I'm sure camera lag has nothing to do with it and the lag itself intentional

[bold plover]

yeah I misunderstood your thing but I get it now. I think what might be happening is the forward vector of your camera is scammed because it's facing you. You might wanna level out the roll of the camera and get the vectors of that instead.

[steel crag]

Hello company, I'm back! Can one of you help me find a solution please? Here is my problem: Here I have a Graph which when I walk on an object (BPC_Item: parent of all SM type objects collectable in the game) this one transforms into another class (BPC_ItemObject) which this one takes the form of an icon in my inventory. Everything is made possible by, if I understand correctly, graph number two (in BPC_Item too). Except that I want this event to be triggered not by walking on it but by means of an input triggering a Linetrace which from its HitActor will identify if the object is of the Collectable class (BPC_Item). My blocking point, at least I hope so, is that my BPC_Item obviously does not set my BPC_ItemObject when I release my input (3rd image: Graph of BP_ThirdPerson). Some more info in terms of graph Inventory_component is part of BP_ThirdPerson and in image 4 here is the TryAddItem function. So if you have the solution, I am certainly interested, but already if at first one of you could confirm to me that the problem is indeed the one that I identified or in any case give me a direction because I am rather lost and going in circles 😅 ! I'll be back

[dawn gazelle]

It should be something like:
Input (On Character or Pawn) > Trace > Call Interface passing in interacting Character/Pawn > Interface on object handles adding object to interacting character/pawn inventory or whatever the interaction should handle.

Alternative using an Actor Component:
Input > Trace > Attempt to get Interactable Component > If Component Valid > Call Start Interaction Function In Interactable Component > Component determines what should happen based on the settings of the actor it is attached to

@steel crag This part is confusing as normally inputs are present on your pawn/character or controller, but you have Item Object as a variable there where this should probably be something that is associated to the item actor you're trying to interact with.

[steel crag]

Hey Datura, Thanks for your answer, are you speaking about the function TryAddItem being confusing ?

Maybe i wasn't clear or maybe i don't understand you completly and i'm sorry about that i'm quite a beginner. i try to have itemobject as a reference of the icon that appears in my inventory once the "item" is deleted

before*

[steel crag]

So to me it's what i'm doing already on the graph you linked, but maybe i should call a function that call the tryadditem function ? Wich is already in one of my components

[empty marten]

Hey peeps,
I've got a small arcade game I'm working on and each level has a timer on it starting at either 1 min, 2 min, 3 min or 4 min. At the end of the level the timer is stopped. The variable types I'm using are Timespan's. What's the best way to calculate the difference between the starting time of the level (example 1 minute) and the time remaining at the end of the level (example 25 seconds)?

[dawn gazelle]

In this image you have an input (the red arrow) and it's attempting to call the "Try Add Item" function with an "Item Object" reference (blue arrow) . This doesn't make a lot of sense as inputs normally would be on the pawn/character, and there shouldn't be a predefined variable of "item Object" that exists on the pawn/character, or within any other component. You'd want your input to communicate to the object you want to interact with, and that object would then do what it needs to do.

Again, normally it'd be as described...
Input > Trace for Object > Object can be interacted with (True) > Interface with Object or Access an interaction Component > Have the target or the component do what is necessary.

[steel crag]

Allright once again, thanks Datura, i'll now try to find a solution about that !

[blissful hound]

Is there an easy way to set the default values of all child blueprints to the default value of the parent blueprint? I have a lot of child bp`s and whenever I change the defaults I have to go through each one of them and reset them to parent default.

[wild sage]

Is there a delay that works independently of time dilation?

[steel crag]

So Maybe you don't care, but i finally made it ! After something like 8 hours of trying ! So glad hahahahaha

[crude dew]

Hi, Im not sure how to solve this so maybe someone can provide me with an answer please, I have recreated Pong but I am finding sometimes depending on how you hit the ball it can get stuck in the middle of the playing field as seen here

Any suggestions How i can ensure that this doesnt happen please?

[crude dew]

This picture kind of shows the trajectory of the ball which seems to me like the ball is having some kind of "spin" which is affecting how it bounces off the walls, Not sure how I would fix this I tried lock rotation on the ball but it done nothing.

[versed sun]

If (Ball == Stuck)
{ don't (); }

[crude dew]

lol sorry @versed sun Not sure I understand 🙂

[trim matrix]

😂

[versed sun]

was joke, reminded me of

But, i would cheat and tilt the black floor slightly tward the bumper

[crude dew]

I did notice that when it first hits the wall with velocity its -711, 3191, 0.000 but thne reduces the X (loses speed with each bounce)

and eventually settles at X : 0.00

So was wondering could i negate X and Y upon contact with a wall to reverse the direction of it ?

[versed sun]

does the ball have projectile component?

[gaunt lion]

hey I just changed my movement animations and now dont have a jump animation here is my jump blueprints. Can someone please help me fix this?

[final python]

I think this node may need some work done. Whenever I print string of my array of all overlapping instances it spits out an appropriate amount of indices as expected, but when I hook the node up it only removes 1 instance. I have finally come to realize though that it is in fact removing more, it's just when the array resizes after removing 1 the other instances are across the map in varius locations.

I mean now that I now what's going on it's an ez fix, but I just feel like since blueprints are more catered towards beginners and sorta ease of use, it would be nice if this node automatically handles the array resize for you.

I'm using 5.2 though, so it may be changed in later versions

[maiden wadi]

What do you mean handled the array resize for you?

[final python]

like

{0, 1, 2, 3, 4, 5, 6}
all of these are static mesh instances in various locations. Say 3 and 4 are right next to each other and you want to remove both of them. when you remove 3 the array will then resize and when you loop again the next time around it will in fact remove 5, because everything got shifted down

so then 5 is like off in narnia and it gets removed but 4 is still sitting there because it was essentially skipped over. It's an ez work around you just have to save the min and max values first, but I just figured unreal would handle that for you

[maiden wadi]

That has nothing to do with InstancedStaticMeshcomponent, that is the Loop. And that is normal behavior.

There is also a version of that that takes multiple instances which you should use.

[versed sun]

Dont remove , set the ISM instance scale to 0, 0 , .01 @final python

[final python]

I know what a loop does, yes the loop causes it to happen. It doesn't seem too hard to have a bool on the node for if you are looping you can check

and it handles the shift for you

[maiden wadi]

I mean.. loops are expensive enough in BP as is. IMO I don't want one more BP check there. As I also said there's a function called RemoveInstances, for plural. So you don't need to loop to remove them one by one.

Also loops 101, if you're doing destructive things to the array you're looping, reverse loop.

[final python]

oh yea remove instances is kinda the whole thing I was complaining about lmao

literally just takes an array and does it for you lmao, I was looping myself

[dark drum]

Remove instances in reverse order. 😉

Edit: Authaer beat me too it lol.

[versed sun]

If you just set the scale of the ISM small to not see it , you aren't changing the array at all

[maiden wadi]

Also on a side note. Try not to spread out ISMs too much. They still have bounds, and they still lose rendering performance if their bounds is too big. If you can occlude them easier or have like a top down camera where you only see so many at a time. If you ISM them all, they don't occlude well, and you still pay heavily in visibility checks.

[final python]

yea that's probably what the remove instances does, sometimes it takes a minute for tricks to cross my mind

[final python]

its foliage with the foliage tool

[maiden wadi]

Ah. I think that grids it automatically then.

Maybe. Can't remember

[dark drum]

As far as im aware, it just adds hierarchical instance static mesh component to an actor. One component for each mesh.

[maiden wadi]

Maybe. 🤷‍♂️ But yeah you'll pay dearly in dynamic shadow costs for occlusion checks and such without some gridding in ISMs sometimes. One great thing about the new PCG tools is that they allow very easy gridding for their areas.

Hello, im making a menu 2D with widget component & gamepad friendly like AC Mirage with the mouse cursor can be moved with gamepad thumbstick, but how can i make my A button simulate a Leftmouse click button ?

hey! I have a countdown timer. I have it set up so that when the countdown reaches 0 it's game over, but I don't want the countdown to start until you reach a trigger box. How can I set that up?

I realize that event tick doesn't work when I check to see if the trigger box is being overlapped

[bold plover]

if u wanna use physics like that you can but you should create a physics material to make it so it won't lose speed. However physics for something like this might have other issues or be inconsistent at times.
You could also do an on hit event or use line trace for faking the collision, and use mirror vector by hit normal to have fully consistent velocity changes.

[brazen pulsar]

How would I change my mouse cursor icon while in game?

[waxen blaze]

Hi, I have this BP graph. For some reason I get different results printing the result from the random node and after that from the Parse Into Array node. But both should be the same.
The combination printed from the parse node isn't even in my default values which you can see on the right side in Details.
Please, I'm dumb and at this point I can't see what I'm doing wrong, please?

Here are the results:
Prague,New Delhi,Sydney line comes from the Random item in array node print (and this line is correct as you can see in the details).
Prague, Beijing, Sydney comes from the Parse Into Array node and it's an incorrect and also non existing combination as you can see in the details panel on the right side.
Then at the end I print Selecting city: Prague, Seoul,Sydney which is just printing with a for loop what is inside a new array after parsing. As you can see it's a new combination which also doesn't exist and the most confusing part is that all these three should be the same.

[versed sun]

You need to do the random only once , and save the result

[waxen blaze]

Oh, every time it goes into the main nodes it does it anew?

Oh I'm stupid I understood the BPs completely wrong..

[stone field]

If you are using the physics engine for this

• ensure friction is 0 so ball does not slow down
• zeroing spin sounds like a good idea, but spin might be fun in some cases

[versed sun]

yup, any Pure node gets recaculated after each white Exec

[stone field]

back when i made a pong from scratch, we just wrote a very simple physics engine for it in which we forced the ball to always keep out of a certain range of angles. perhaps something like that may be necessary

[waxen blaze]

Oh I see, so the For Each Loop doesn't source the array just once but calls that branch every time? Like here in this:

Thank you so very much, I thought it was making local variables for these side branches. @versed sun Thanks!

I tried but it doesnt work

[radiant wren]

oh :/

[faint creek]

The cast is of a task in my behavior tree

so in the AI

[trim matrix]

Beuh

[faint creek]

AI behavior tree

[trim matrix]

Taks isnt the player

[faint creek]

??

[trim matrix]

Where is your ai behavior tree?

In thr picture, it seems like you think that ai behavior tree is in your player..

[faint creek]

In my AI

[trim matrix]

Find a way to get that actor

[faint creek]

Ok I have to specified that my behaviuor tree is not "in some actor" , I just call it in my BP_Ai enemy

[faint creek]

I've tried to get teh behavior tree and also the actor but nothing

[trim matrix]

Where is your code at?

Like in what bp

[faint creek]

In my Ai controller

But it doesnt work

ok I solved and it compile

However it doesn't disable input 🫠

[faint forge]

what would be the better approach for one mouse that is controlled by 2 Player Controller by Turn? for a Turn base game. I starting setting up everything for 1 player and now I just added this code to the game mode. 2 Player Controllers are added, but when moving or clicking mouse only the PC_0 (Player1) is printing its Display Name

so kind of setup with custom events or rep notify that take the input always in PC 0 but pass it to PC 1 when is Player 2?

[radiant wren]

Not sure how I'd go about this, anyone know?

[faint creek]

It works directly in the task

[karmic rampart]

I'm trying to have a sprite emulate a Billboard but keep the axis rotating only along the Z axis. This seems to work until I walk beside the sprite, then it's not rotating. When I get behin the sprite, it turns and faces me. How can I always keep this on the camera?

[spark steppe]

you'll most likely hate it

just use the camera rotation (yaw) for the sprite

that's it

unless you really want to take the actor location and whatnot into account

[karmic rampart]

I'm really new to Blueprints and was following a YouTube tutorial. Can you show me an example of what you mean?

Like just get GetActorLocation(self) and connect it to Find Look At Rotation?

[spark steppe]

you just get the camera rotation, break the rotator, take the yaw (eventually add 180 deg, if it's flipped) and set that yaw for the sprite

[karmic rampart]

I'm not seeing how that looks in the graph. Is the first part the Get Player Camera Manager?

[spark steppe]

yes, and you can afaik get the camera from that

[trim matrix]

How does it work when the camera rotate but not the mesh?

[karmic rampart]

Okay.

[spark steppe]

i think my "solution" might not look ideal in all cases either

keep yours, and get the camera and use that location instead of the location of the camera manager

[karmic rampart]

I got this far before getting stuck.

[spark steppe]

yea wait, try the last suggestion first

replace the get actor location which is connected to the camera manager with get camera location (if that exists)

[karmic rampart]

This is what I see.

[spark steppe]

starting UE, gimme a minute

[karmic rampart]

Oh, I got it.

It does exist.

I tried running it, same issue. The sprite stays in one spot until I walk around it and then its back side turns and faces me.

I can stand at its side and barely see a straight line of the sprite. I have to walk in front of it for it to turn.

[trim matrix]

How to make it so the camera doesnt rotate the mesh?

[spark steppe]

try this

the upper location is the camera location

and ensure that your sprites forward vector is X (so that the x-axis points forward in the viewport)

[radiant wren]

Hey @spark steppe would you be willing to take a look at this, see if you know of a node that could save me here XD?

[karmic rampart]

What does the return value on the last node go to?

[spark steppe]

to your set actor rotation node

[karmic rampart]

Oh okay

[trim matrix]

@spark steppe Would you be willing to know about this?

[spark steppe]

no, i don't know anything

[karmic rampart]

@spark steppe I don't have a set actor rotation node.

[spark steppe]

make one

[trim matrix]

You do know a lot 😩

[karmic rampart]

Or do you mean Set World Rotation

Ok

[spark steppe]

you can also just rotate the sprite component if you want to, but then it should have no rotation offset (since that will be overriden)

which is why i chosed to rotate the whole actor

[karmic rampart]

Whoa, he's blinking around in 4 places like a circle.

[untold niche]

Question: I'm trying to get a list view widget to update a current entry, rather than adding a new one, I've tried using the node "Regenerate All Entries" but it just seemingly does nothing, I know I'm missing something but I don't know what, any would help would be amazing

[spark steppe]

show your blueprint as it is now

[spark steppe]

yea the top location is wrong

it should be the camera location, not the sprite location

so get camera manager => get camera location

[karmic rampart]

Do you mean up here?

[trim matrix]

🔥

[karmic rampart]

He's moving around when I walk toward him.

[spark steppe]

you probably have a location offset in your sprite component

look in the details of it, is it not exactly in the center?

[karmic rampart]

I had to move the feet up to (0,0,0) but that was it.

[spark steppe]

hm, offset on z-axis is fine

can you show the whole blueprint hierarchy please?

the top part where it lists the components

[spark steppe]

and the actor in the level?

should looke somewhat like this

[karmic rampart]

He's jus standing at 0,0,0

[spark steppe]

with x facing forward

[karmic rampart]

But facing the right (forward x)

[spark steppe]

i can only imagine that it get's the wrong camera

try get player pawn => get actor location as top input

that would face it towards the player instead of the camera

just to figure if the camera location is the problem

[karmic rampart]

He moved from his location to the corner of the room (a table size away), and didn't seem to rotate when I got closer.

[spark steppe]

i would test that on an pretty much empty test level

at least get rid of that wall to ensure that it's not a physics/collision issue

[karmic rampart]

I put him outside. While running the game, the actor moved about three houses down. It rotates until I get to its sides (facing shoulders)

[spark steppe]

so it has physics and gravity enabled!?

and if you swapped the camera location for the actor location, it will ofc, try to align with the character instead of the camera

[karmic rampart]

Gravity is on, not physics.

[spark steppe]

i think your issue now is the collision, not the rotation logic

[karmic rampart]

He doesn't have any collision. You can walk right through him.

[gaunt lion]

hey can someone please explain to me how I would pick up multiple different items off the ground. Can I make one item blueprint and just change what it is. Or does each different item need a new blueprint. Please let me know thanks.

(im trying to be able to pickup rocks and wood off the ground)

[karmic rampart]

So one connector was loose. Still seeing same thing, and now skiing along the snow parallel to him going in one direction, seems circular.

Updated

When I walk toward him, he goes backwards currently.

[rugged wigeon]

You want each item to be a child class of some parent generic "pickupable item"

[karmic rampart]

@spark steppe This helped.
The actor stays in one spot now. But not rotating to face the player camera.

[spark steppe]

that's illegal

the math that i showed works fine for me

so your issue is something else

make an empty actor just with a plane facing x-forward and put the logic in there

and then start to compare what is different to your current actor

#umg

[willow gate]

Yup. It was muted for me for some reason. Thanks

[karmic rampart]

@spark steppe I feel stupid. I moved my old BP nodes downward (the nodes prior to talking with you), disconnected it from Event Tick thinking it won't execute. I spotted those old nodes just now, removed the code, and the actor stays in one spot now. The rotating... I'll have to relook at your original nodes and try it again.

It worked 🙂

Using solely these nodes this time.

Well, he's rotating, but not always staying at the same spot.

And not fully rotating. Wth

[cedar remnant]

Hi all!
Trying to create a grenade that only detonates once it's slowed down past a certain velocity threshold. Trying to take advantage of the following nodes pictured in this message.

I have an initial projectile velocity that is set and then I have the mesh simulate physics so that it slows down and comes to a stop under the forces of friction. The problem I am facing is that the "velocity" never drops. In my print out, the velocity never changes from what I set it to initially. What parameters of the projectile movement component should I be changing to force this to drop?

[karmic rampart]

@spark steppe It works now. I did an old tutorial with the removal of my old nodes. Thanks for helping.

[frank heath]

Hello

I'm worink on archviz explorer, it was using bp_explorerpawn, now without changing the gamemode how can I switch this to third person in runtime with the help of ui button and I need to be able to switch back to bp_explorerpawn

Can anyone help me out with this

[quaint fable]

How could I have it so a countdown timer set "on tick" only starts counting down after overlapping a "BP_TriggerBox"? I created this function, called "Start Time Limit", which checks if the character is overlapping the actor. However, the countdown starts as soon as begin play starts

[dawn gazelle]

A time limit doesn't sound like its something that should really be associated specifically to your character and instead be a part of the trigger box itself.
You could utilize the OnOverlapBegin event in the BP_TriggerBox blueprint, cast the "Other Actor" to BP_ThirdPersonCharacter to ensure that only the character will start the logic, and then have that do a looping "Set Timer By Event" node. You can then have that event check how many seconds are remaining and if there are any seconds remaining, subtract 1 from the count of the seconds. You shouldn't need to keep track of minutes and seconds separately as 60 seconds make up a minute, so you can use some basic math to determine the minutes and seconds of a particular total number of seconds.

[gaunt lion]

can someone please explain to me why this doesnt work?

[languid spear]

you need a variable hooked to the node that says “error”. it doesn’t know what variable to change.

[gaunt lion]

if im storing values for collected objects should it be a float or int

[languid spear]

also that branch doesn’t make much sense

an int should be fine

[gaunt lion]

ok

im trying to get the existing value then increment it up by one everytime it is picked up. Is there an easier way of doing it?

[languid spear]

hook “total stone” to the left side of the increment node. then hook the left side of the increment node to the set node.

[quaint fable]

That makes a lot of sense. Originally I was going to do it through the Triggerbox Blueprint until I watched a tutorial. How can I have the event check how many seconds are remaining?

[dawn gazelle]

Seconds >= 0

If true > Reduce the seconds by 1.
If false > stop the timer, signal that the countdown is finished.

[languid spear]

and get rid of that branch altogether

[quaint fable]

@dawn gazelle so basically what I did here in the character BP, but do it in the triggerbox BP?

[gaunt lion]

its not keeping the value tho. when i pick up 3 stones it just prints 1

did I do something wrong?

[dawn gazelle]

The "Total Stone" variable exists on the actor that you're ultimately destroying. So if you're destroying the actor, then the "Total Stone" value goes with it.

[gaunt lion]

oh ok so where should I put the variable? on the parent bp?

[dawn gazelle]

On whatever you want to use to actually keep count.

[gaunt lion]

alright thank you

[gaunt lion]

I put the variable on the master bp and it still does it do you know a fix?

[dawn gazelle]

You need to store the value on something that isn't going to be destroyed.

[gaunt lion]

so could I store it in my 3rd person player bp?

[dawn gazelle]

Sure

[gaunt lion]

and I just have to cast to it to get the variable?

[dawn gazelle]

Well, you are already using an interface to communicate to the object. You don't necessarily want to use a cast get a reference to your character.

[gaunt lion]

ok

i feel like im really overthinking this, but im trying to make a platform the player can walk on forever- im trying to set the actor location of the cube mesh as the player's x and y, but obviously, this leads to the velocity just getting multiplied every frame. are there any workarounds?

[gaunt lion]

im sorry for the constant questions but how do I use the integer from my 3rd person bp in my stone bp?

[gaunt lion]

I am trying to make a simple pickup system to pickup rocks and save them as an integer. I am running into an issue that when I actually pick up the rock the value doesnt increment up. Can someone please help me figure this out thanks

[ancient siren]

the ++ node is not connected!

[gaunt lion]

what does it need to connect to ?

@ancient siren

[ancient siren]

put this in between destroy actor and print string

the "++" node has execution pins (the arrows) and if those arent connected to a function of some sorts, it never gets called

[gaunt lion]

@ancient siren
so I did that
but the value isnt going above 1

everytime I pick up a rock it just stays at 1

[ancient siren]

oh its because the instance of the rock is getting destroyed, and the value is different for each rock. i would make this a variable in your player

[gaunt lion]

How do I call it from my player to my rock bp

@ancient siren

[ancient siren]

is your game single player?

[gaunt lion]

yes

[ancient siren]

lmk if it doesnt work

[ancient siren]

bump

[gaunt lion]

@ancient siren I dont have the blue target on the last set stone. do you know why?

[ancient siren]

drag out from the blue part of the cast node

[gaunt lion]

i tried and nothing

[ancient siren]

drag out from the "as (player name)" and type in "set total stone" !

[gaunt lion]

ah ok gotchu

@ancient siren now its not picking up

[ancient siren]

idk what that means

[gaunt lion]

Im trying to pick up stone and add 1 to the int

now its not letting me pick up the stone in the game

[ancient siren]

you arent destroying the actor or printing the value to see if it works, but if you are interacting, i can assure you the value is going up

[gaunt lion]

oh im dumb lol

haha thanks

[ancient siren]

bump

[gaunt stirrup]

does anyone know how i can change music on a widget button?

[gaunt lion]

@ancient siren it worked thank you so much

[frosty heron]

Use the on clicked event if you want something to happend on click

As to change the music, get the reference to your audio component, where ever it lives and just change the sound asset.

[frosty heron]

Wdym by a platform the player can walk on forever? Are there any examples from video games?

[gaunt stirrup]

i tried to get a reference to the audio component in the widget blueprint it wont work 💔

[frosty heron]

Skill issue. It's trivial matter

[ancient siren]

its more just a bugfix sort of thing. i want the player to be able to move infinitely in any direction

[frosty heron]

What's stopping the player from moving to any direction?

Having them stand on top of a box doesn't stop them from moving

[ancient siren]

well i could make a box, but boxes cant be infinitely large

[frosty heron]

Still no clue visually

[gaunt stirrup]

not sure what im doing wrong, i can reference it in the level blueprint but not the widget blueprint?

[ancient siren]

well, are there any fixes you know besides just making a really big box?

like, do you get what im going for here?

[frosty heron]

No clue when I can't even picture what the issue is.

[frosty heron]

Don't use level blueprint, other bp classes including your widget can't reach the level bp

[ancient siren]

oh, so the issue is that when the player moves with the code i have, it keeps on setting the location while the player is moving. its hard to explain, its sort of like walking on a surface with zero friction

ill send a video if needed

[frosty heron]

Well that's what Ur code is doing

You Set the location every frame

[ancient siren]

so what do you think?

i was thinking about connecting it to whatever is called when a movement key is pressed

[gaunt stirrup]

i figured it out i think lol

shoutout sequence nodes

[crude dew]

thanks for the reply! , I,ll take a look into that. 🙂

[crude dew]

Thanks for the reply, Not really sure where i would start with writing a physics engine for the ball but definitely something i should at least consider jumping in feels like a tonne of work for a basic ball, (Why did think pong would be basic no games seem basic to me atm lol) 😄 Kind of feels like pong games just use a set actor to "simulate" a bouncing ball rather than actual physics.

[crude dew]

Yes I am using the physics engine for this friction is 0 but I think the spin is causing the bouncing inconsistency's which is causing the ball to enter a weird trajectory, A bit like when you side spin a cue ball in snooker it wont bounce at a flat 90 degree angle.,

[frosty heron]

Don't see how sequence node have anything to do with getting a reference.

[gaunt stirrup]

it doesnt

just expressing my love for them

[frosty heron]

You first want to create audio component.

Then you want to pass that to your widget

Then on your widget button click, you simply use the audio component that is passed and change its sound asset

For the sake of simplicity, you can add an audio component to your player character

Use that to play your music

[gaunt stirrup]

this is just in a menu before entering the game

[frosty heron]

You can create an actor bp then

Call it music manager

Place it in the main menu level or where ever you want to have music on

That actor will hold the audio comp

When you create your widget, you can get actor of class, music manager, get the audio comp and pass it to the widget

[gaunt stirrup]

trying to use booleans from game instance as conditions for a couple branch nodes but it still wont work, no errors, am i doing this wrong?

off a button widget

[frosty heron]

Debug

[stone field]

There are a couple of pong clone tutorials on youtube, probably worth taking a look to see how others have fared

[crude dew]

@Karma I,ve found some of them thank you, I didnt realise it would be so hard to create a bouncing ball. xD I,ve managed to get it to endlessly bounce back and forth but the second you put any angle on the ball it either loses speed (With 1 Restitution, 0.0 friction and no gravity) or it with (Max Restitution, 0 friction, no gravity) it speeds up within 2 bounce and go completely bonkers in kind of weird directions, I think others are using Projectile Movement Components which will be my next try as using the Physics engine inside UE seems to produce odd results (Which could be accurate but I dont have a science masters) xD 😄

[grave relic]

Hey!
How can I retrieve a user's Steam ID?
I'm talking about the number that identifies the user's account to target it correctly, not the name of the account?

[primal hare]

I have a danger bar for player. How can I add some random noise to keep the bar animated to convey presence of danger?

Couldn't find any node in BP

https://forums.unrealengine.com/t/simple-1d-noise-function-for-use-in-blueprints/52872

found this, now trying it

[marble tusk]

There should be a built-in noise function. I've used one recently. Forgot the name of it, but it likely has "noise" in the name

[primal hare]

yes found Perlin noise but it is not doing anything. However Random float seems to be doing the trick have to clamp it though

perlin

[marble tusk]

Well, the input value needs to change in order for there to be noise. It's deterministic, feeding it the same input value outputs the same noise value. Random float on the other hand will just get a random float each time

[primal hare]

That is contrary to how noise works in DCC in general. I'm using noise to change the value in first place

Random noise is flipping to fast. How to control the frequency of the noise/change?

trying to use Finterp ease in out node

[marble tusk]

This is why the perlin noise function has an input value. For example, here I used perlin noise to modify the vertices of a dynamic mesh to make the double yellow lines wiggle back and forth. I used the world location's X value as the perlin noise input so the output would be a smooth noise value across the mesh. If it were just random floats it wouldn't be smooth at all

[primal hare]

is there a way to control frequency and amplitude?

[marble tusk]

Multiplying the float going into it for frequency and multiply the float going out for amplitude

[primal hare]

ah cool

[marble tusk]

It outputs 0-1, so you could instead do a remap if you want it in a specific range which doesn't start at 0

At least I think it's 0 to 1. It might actually be -1 to 1. I'm not able to check at the moment

[primal hare]

I need a smooth heaving values to feed my danger meter

everything is fluttering too fast at the moment and is distacting

Timeline is unavaible in WBP it seems

[marble tusk]

Well, feeding it a random float will basically just be like using a random float to start with

[primal hare]

there isn't any time function to change value here.

or atleast I don't know or find

[marble tusk]

So this is something that's happening over time, so time is the input value for the noise. There are definitely functions for time related things you could probably use. I don't know them off the top of my head to tell you though, and I'm not at my PC to search for them

There might be something like 'game time' maybe. I don't know

There's "Now" which gets the real world time, and you could convert that to a float somehow which there might also be a function for

However, if you intend to use time dilation to do slow mo then "Now" probably wouldn't respect that. Also, pausing and playing would probably cause a jump

[trail root]

for future ppl, this is how i managed to fix this - now camera angle is not affecting move speed and character movement is relative to camera postion.

[primal hare]

no worries thanks for your help!

[cerulean mango]

I'm having trouble to add a structure to an array, my E debuff list is still empty, my debuff and turn count variable are both valid, i don't know why this is not working

[faint pasture]

Is this in a function?

[cerulean mango]

In an Event atm but i was about to move it in a function cause this is the only event i have to implement this system

[faint pasture]

Does that breakpoint get hit?

Show more of the code

Also try with a regular add node, just feed it a make struct

[grave relic]

Hey im working with some projectiles and having an issue with them flying through static meshes, I have tried two solutions but neither works. The projectile does not despawn but ignores the static mesh. I dont know if im doing this the right way, but I dont know how I would do it otherwise.

[thick elk]

Hi
I get this error during play test on the built game.
[2024.08.06-09.17.18:701][534]LogWindows: Error: Unidentified failure for object TextBlock /Engine/Transient.GameEngine_2147482600:BP_GameInstance_C_2147482557.None.None.DamageText, hash itself may be corrupted or buggy.

Does anyone know whats that and how to fix it?

[cerulean mango]

Yup the breakpoint get hit, the blueprint is actually super messy but i hope you'll understand, I just switch on my debuff type, and thenapply a flat reduction to my stat, and i manage the remove and timer in function, i also got this in the console

[undone bluff]

slow projectiles? is a collision happening to begin with?

[mild jacinth]

if i spawn a player manually and even after setting input mode to game only, the input only works if i press mouse button. why is that so?

[grave relic]

It is fireing, it does trigger on world dynamic, but not on world statics for some reason, at least not consistently. I have it trigger some times...

[undone bluff]

From what I understand your issue is overlaps not happening which is either due to how the collisions are set up or because your projectile is fast enough to pass through without an overlap?

[novel goblet]

How do I fix this? Its read only so I have no way to right click refresh it or pin it correctly.

Think I got it I went into view bindings and cleared and redid it

[grave relic]

Hey,
I need to do this "curl -X POST -d "key=ID-KEY" URL.com/update-game-data.php"

But not in curl.
I just have to send the "key" and "value" argument how do I do that here?

[candid whale]

how do I get the gameInstance class in the construction script?

[dark drum]

In terms of the editor, when the construction script runs, the game instance doesn't exist at that time so the answer is you don't.

[candid whale]

I only need the class though, not the object. Should be possible?? There's configuration in there that should change my code behaviour :/

[frosty heron]

get the class for what?

well your Game instance will be null if you don't have a game running

can't get the class of a null object

[dark drum]

As far as I know you would have to get the game instance and then get the class from it but I as i mentioned, it doesn't exist until you start the game. Adding to this, you can only use one game instance and you wouldn't be able to change it at runtime.

[candid whale]

hence why I'm having to find an option other than "GetGameInstance". Currently I'm using a BlueprintFunctionLibrary that has a duplicate variable entry for the classOf gameInstance. But that's code duplication and I'd really like to avoid..

as for what it's doing, there's Image references for buttonBackground for example that should be displayed in-editor

the setting is inside the Project Settings, so it has to exist somewhere..

[frosty heron]

setting for what?

[dark drum]

Not that's accessible via BP but to be honest it sounds like the data you're wanting should probably be a data asset instead of being stored on the game instance.

[candid whale]

for design-time elements inside the editor. an example being an image or a string that switches elements on and off

[candid whale]

what benefits would a data asset provide over a simple Image variable?

[frosty heron]

sure, I don't see why you want to use game instance for that

deffinitly not the right place

Try Data Assets

[grave relic]

Its not the speed, slowed them down by a lot(essentially slow motion) and it still went through my static meshes. I think its worth to mention, they are instanced meshes that are spawned.
