blueprint

[frosty heron]

It's probably consumed by some other bp

Have you check with print string if your E works or not?

[desert juniper]

i like to recommend C# because it's a much easier language to understand than C++. Unreal uses C++ but it's like learning to drive a manual transmission for your first car. may be a bit easier if you start off with something a bit more approachable.
Conceptually almost everything up to 27 is applicable.
Implementations are not. but that's not something you don't have to be concerned with until you actually need it.

I do get a lot of hate for recommending C# as a foundation to programming in this specific discord server so that's just my take. I used to teach, and my method was to make learning more approachable, instead of telling everyone to dive to the deep end right away. take a look at both sources. and see what you like. either way you'll definitely have a better foundation going forward

what i strongly believe (and im sure most would agree with me here) however is that you shouldn't follow blueprint tutorials to learn programming. I have yet to see a good course that actually teaches you how to good programming concepts / principles.

[faint creek]

No it doesnt work

[faint creek]

how can I see it?

🥲

[minor creek]

is this wrong? it doesnt destroy some of the spawned actors

[frosty heron]

You will have to look around where you use the E input. Ctrl f type the key and click the binoculars

Then check for every bp that uses it. Click on the event input and see if consume input is ticked

[faint creek]

Binoculars?

[frosty heron]

On top of that your widget may also consume inputs

So that's another thing to check

[faint creek]

Yes is consumed in two flibook actors

But only when the player is begin overlap the box

[frosty heron]

Well if your key is consumed somewhere, the same input most likely not gonna work in other places

Because it's consumed

[faint creek]

Is there a way to consume it in multiple actors?

[desert juniper]

you can untick consume.

[faint creek]

I tried but it doesnt work

[frosty heron]

Like @desert juniper shows but usually if you have to do that. You have design problem

[faint creek]

It doesnt work only in this specific BP character

[frosty heron]

That's all I can think of tbh.

Either keys are consumed by other bp or UI

[faint creek]

I'm putting all E key to not consume

[frosty heron]

Might be a needle in a hay stack if you have inputs everywhere

Check your input mode?

Might be set to UI

For it to work ,input mode must be at least game. Or game and UI

[faint creek]

Nothing

All happens when I created two actors, and then I change it making the "Reparent blueprint"

[frosty heron]

Is this done in for loop? Because for loop happend in a single frame.

If that's the case, only your last actor most likely get destroyed.

What you can do is set a life time in the actor being spawned it self, no need to tell it to commit the unthinkable from the "spawner"

[minor creek]

it spawns the actor when bullet hits to surface

i want that actor destroyed after some time

[marble tusk]

Try using "set life span" on the spawned actor instead, that way the spawned actor will be responsible for destroying itself

https://unrealdirective.com/tips/actor-life-span

[faint creek]

Anyone know a solution?

[desert juniper]

again, something is likely consuming E.

look in your character BP, level BP, etc

[faint creek]

Ok but I uncheck everything and it happened also at the start

[faint creek]

ooook it works

I didnt see in the level blueprint

[mossy hemlock]

can someone help me with ads?

[faint creek]

Thanks a lot guys 🙈

[frosty heron]

For sanity sake, don't pop inputs everywhere

It can be a needle in haystack

[faint creek]

But what is the best alternative?

[frosty heron]

To do what

Normally inputs are binded in player controllers

Or characters

Depend on your game

If you just want to do some test, use either of those two and don't place it else where

If E is to interact I would have that in the player controller

Characters if you have different character you can posses , e.g. a car or a plane

[faint creek]

wow okok

Yes maaybe its better🤓

thx 🥹

[frosty heron]

You want to avoid level bp, they are ok to test around tho. You can always use custom event for that as well.

[desert juniper]

1 step above literal key inputs is action mapping. and another above that is the enhanced input system

[frosty heron]

💯 I don't use those legacy keys beyond testing

Enhanced input just inheritly soo much better

[desert juniper]

(not a architectural solution to how to handle inputs, just as a replacement for hard coded key values)

Just realized unreal's deprecating action maps

[maiden wadi]

Also less deprecated.

[frosty heron]

is Enhanced input being deprecated?

[maiden wadi]

The old input actions are.

[frosty heron]

oh yeah

I'm 100% sure it's not going to be completly removed tho

[maiden wadi]

Eh, 7.2 maybe.

[frosty heron]

wouldn't mind using them in empty project without the extra steps to setup IA

[maiden wadi]

You can still use the direct keybinds for quick stuff. They're just debug marked so won't work in shipping.

UE5 is killing me with these context fuckups.

[mossy hemlock]

anyone know how to get rid of the error?

[maiden wadi]

You're using the not valid side of the IsValid node to do things that should only be done when it's valid.

[mossy hemlock]

idk why but before it gave me more errors now no9ne thx,

would you happen to know why its not adsing? i have the event and input for it

[maiden wadi]

You plugged the set node in?

[mossy hemlock]

yes i have it on the one i showed the anim one too along with it turning on and off in a BP

[frosty heron]

just show the latest code

the fixed one

[frosty heron]

your ADS pin is still not plugged in

what's the actual issue here apart from that?

[mossy hemlock]

what do i got to set it to?

nothing erlsew the error are gone it just wont work

[frosty heron]

Brother don't do multiplayer when you are at this level

it's making learning many times harder

oh wait

[mossy hemlock]

yeah that dident work

[frosty heron]

you want to set the ADS in your ABP to the character ADS

drag and drop the isAds from the variable window to an empty space, select set

it seems like you are following tutorial or some sort and blindly as well on top of that.
you need to actually understand what the code does and the purpose, informing the ABP of the ADS variable change is a start but not a sure fix, you do need to check where in your anim graph the boolean are actually used

[mossy hemlock]

ok. thx

[weary nimbus]

How do I get my character to not try to walk downwards when I point the third person camera is pointed down? I know that somewhere the player controller is basing pitch off my camera view, but all the Use Controller Rotation ____ options are turned off on my BP.

All the solutions online are for first person cameras which isnt working for me

[maiden wadi]

Deleted GetPlayerController, GetControlRotation, GetForwardVector, and GetRightVector.

Find the nodes GetActorForwardVector, and GetActorRightVector and use them instead.

[weary nimbus]

Issue with this, character no longer strafes but now spins in circles when I hit A or D

I also still need it to go in the direction the camera is facing when I hit W

[maiden wadi]

Then you have some form of auto turning on which is inconsistent with the term strafing.

[weary nimbus]

I just put in strafe for my own organisation

That's just for me to remember

[maiden wadi]

You could put your old nodes back. Create a Rotator from XVector from the Forward and Right vectors, and break that rotator. Make a new rotator with the same Yaw, but Pitch and Roll at zero.

Also consider using GetController instead of GetPlayerController.

[weary nimbus]

How come, what would the difference be?

[maiden wadi]

GetPlayerController gets the first playercontroller on the machine. If you have splitscreen or are a listenserver, this can cause issues. Less of an issue for singleplayer or clients in a multiplayer game. But it's still good practice to understand that you want to use THAT pawn's controller instead of some random one.

[weary nimbus]

Oh yeah that makes sense

Don't plan to make it mp but I'll keep that in mind

[weary nimbus]

This method works though, thank you so much

[civic oar]

Hello all,

I am trying to make a racing game with a vehicle control scheme akin to Halo’s vehicle control. I did this successfully in Unity Engine around a year ago with some online help, so just translating this to blueprint and Unreal’s animator is my main issue.

For those who have not played Halo, the right thumbstick controls the camera orientation and the left thumbstick Y-Axis controls the throttle and brake. The steering of the vehicle always orients the vehicle to the direction that the camera is facing. Would anyone mind pointing me in the right direction for achieving this in Unreal?

(For reference, I made the C# code provided by the user in this link work for my purpose in Unity: https://discussions.unity.com/t/has-anyone-ever-made-a-vehicle-control-scheme-similar-to-halo/464094/2)

[zealous moth]

what's a good method to make an AI not move and later move on demand?
I tried using a BB condition, but somehow it didn't work.
Unpossessing and repossessing doesn't make the AI BT work either.
My dumbest workaround is to set the movement speed to 0...

[lunar sleet]

There’s a StopMovement node. You can also StopLogic from the BrainComponent if you want to stop the tree entirely

[zealous moth]

apparently the service has to be spammed at the action instead of the head selector in the BT, which is stupid... but it works...

because at the head selector, it is only called once

[lunar sleet]

What service

[zealous moth]

this

[lunar sleet]

Well yeah, the tree doesn’t get reevaluated above the first selector since you have no decorator or additional branch on it (and the active branch would have to abort entirely to go all the way up)

[jolly oracle]

Curious Question: Does the Timeline, "Finish", Execution Pin fire when it's being reversed? Does it finish when it reaches the Beginning?

[lunar sleet]

It finishes both ways last I checked

[lunar sleet]

But it’s Completed not Finished, no?

[primal hare]

Yikes! I didn't know that nodes which are not even connected with execution pin get loaded in memory! https://youtu.be/EQfml2D9hwE?si=3N4r95O6V9dUz9FI&t=650

I thought anything which has no execution was ignored. Or is it just for Cast nodes?

[jolly oracle]

Sorry about the delay! The Timeline I'm looking at the, "I'm done", pin reads, "Finished"

[gentle urchin]

Finished is in both directions

Accompanied by the output direction enum

[worldly skiff]

Is there any efficient way to pass parameters to an event that is called by a timer? A global won't work, because it might be overwritten before previous timer is finished.
Some sort of hashing would work, like saving an int on a timer key, but then again there is no way to get an elapsed timer from an event.
The only idea that comes to my head is to spawn an Object that holds all the logic (the timer and the data), but that seems like an overkill.

[gentle urchin]

This looks a bit flawed?

Wouldnt the cooldown reside in the skill or skillmanager?

And you can get elapsed time, by the timer handle

Then ability or ability manager would have a dispatcher for the UI to signal its cd is done (and update cd tick)

[maiden wadi]

Or just using GAS where these systems are already made for you. 😄

[barren tangle]

hey i try to use the trace sphere by channel

sometime it trigger lot of time when it touch the target

i don't understand why

so the basic movement is like that

blue vector, and with the impact point of the radius of the sphere trace

it generate the normal to change the direction of the sphere

most of the time it works well

[sudden monolith]

how do I do a infinit loop?

[barren tangle]

but sometime it act like that

[maiden wadi]

While(true)

[sudden monolith]

oh ok

[sudden monolith]

you mean use a while loop?

[barren tangle]

sometime it act like that

[maiden wadi]

I guess so? Why would you want an infinite loop?

[barren tangle]

like if there was multiple collision point at the same time 🙂

[sudden monolith]

no it gives an error saying that its an invinit loop and that it doesnt work

[barren tangle]

😄

[sudden monolith]

basicly I have a flashlight and I want it to flicker like every 1-10 secounds

[barren tangle]

show us the blueprint 🙂

[gentle urchin]

Definetly 😆 Perhaps a tad more complicated tho

[barren tangle]

maybe you call a function during a function and call back the same function again. it's also a way to generate an infinity loop

[maiden wadi]

Less complicated than anything he's making. Make ability. Apply CD GE, move on with life.

[sudden monolith]

basicly this is what I have rn so I just connected the last pin to the first which doesnt look clean at all

[sudden nimbus]

better to use timers for this

[gentle urchin]

Connect it to ui, block with tags, , Damage calc etc etc?

But yeah it quickly piles up even with custom systems

[gentle urchin]

Sounds simple on the surface, but once you start thinking about it in detail... 😅

[barren tangle]

this will always the same value

[sudden monolith]

?

[barren tangle]

so you will always go to false

[sudden monolith]

yes

but this is not the loop I meant

[barren tangle]

but if you always go to false you are into an infity loop

[sudden monolith]

yea I fixed that

but I meant

this here

like if that is possible with a node

[barren tangle]

put a print after the random int float

[sudden monolith]

instead of connnection the last pin to the first?

[barren tangle]

to see if the value change on each loop

[sudden nimbus]

yes it's called Set Timer

[sudden monolith]

it didnt there but i fixed that

[sudden monolith]

oh ok

[sudden nimbus]

you can set a timer once with a random delay instead of a loop so that you get some random timings instead of the same interval every time

[maiden wadi]

All the more reason I say GAS. The foundation is already done for you and all you have to do are those extra things. GAS isn't any more complicated than any other system would be if you needed the same things and you don't even have to use a vast majority of it. Rolling your own ability system is a daunting task that always seems easy at first. And then there's that next little thing. Before you know it, you're months of work out creating and debugging code that is literally handed to you already in the engine.

That said. I do still hope they're planning on helping their scripter implementations. Would go a long way to be able to have attributes not from a third party plugin. Doesn't bother me, but it would help the perception about it a lot.

[sudden monolith]

set it by event? or by funtion?

[sudden nimbus]

by event ensures you can still use async nodes like delay and makes it easier to see all at once

by function will require you to make a function which cannot be async

[gentle urchin]

Im surprised they didnt out of the box. But then again, they still only got header previews. Feels like they'd be able to make native c++ classes from bp base classes already

Along with enums, structs, and heck, attributesets

[barren tangle]

what is that node

[gentle urchin]

Intensity?

[sudden monolith]

it set the intesity of the flashlight

[barren tangle]

ok

[sudden nimbus]

it do the flicker 🙂

[sudden monolith]

I did it now like this but it gives an error

[barren tangle]

you plung the beging play to the set timer by event

and you create a new custom event that you link to the event of the node

[sudden monolith]

oh ok yea I see what u mean

[barren tangle]

like that the timer will call the LoopEvent on each Time

[barren tangle]

no one have an idea about that sphere trace by chanel?

[maiden wadi]

Sphere trace won't cause that. It's just a simple trace that'll go til it hits something and stop. If you have multiple hits like that, it's your own logic calling more than one sphere trace.

[barren tangle]

but that can be related to the speed of the object before hitting something

[sudden nimbus]

kind of hard to follow but this picture makes me think you are receiving multiple sphere trace hits when you only expect one. a sphere trace gives you all overlap hits and up to one colliding hit. the collision presets define what is a colliding hit and an overlapping hit.

[barren tangle]

yes but if my object move faster. than expected? will the collision point be unique?

[maiden wadi]

What does an object's movement have to do with a sphere trace?

[barren tangle]

sphere trace will tell me when i have an impact

[maiden wadi]

Why doesn't the object tell you that?

[barren tangle]

if my object move fast he is not able to tell me that. someone suggest me to use trace for that

but it's the same in fact

[sudden nimbus]

are these projectiles?

[barren tangle]

it's a pawn with a component : FloatingPawnMovement

and i increase the pawn velocity over time

but with faster velocity, the collision are not detected properly anymore

so the object go though the wall or things like that

[sudden nimbus]

if they are projectiles (meaning anything that is "shot") and they are moving very fast, then you can miss an impact event when they have collision response, indeed a sphere trace would avoid that because you are effectively doing a trace projectile instead of a physical projectile. You can also enable continuous collision on the projectile which sometimes helps if you don't want to do a trace projectile

[sudden nimbus]

sounds like you might want to try continuous collision

[barren tangle]

and when i touch i change the direction by the normal of the impact

[maiden wadi]

You're using last frame's velocity?

[sudden nimbus]

also, setting velocity directly will exacerbate this issue, if you can instead apply force you may get a better result

[barren tangle]

i use only the

[maiden wadi]

Why not just use a PMC with no gravity or slowdown?

[barren tangle]

don't know the last frame's velocity

[maiden wadi]

You set it above after your trace.

[barren tangle]

what is a PMC?

[maiden wadi]

ProjectileMovementComponent

[barren tangle]

is it better?

i will test

[sudden nimbus]

it is purpose built for fast collidables, but are you making a billiards game or something? if so, I wonder if PMC is going to work for that

[gentle urchin]

Ccd only works so far. Traced projectile cant really miss with a decent implementation

[untold fossil]

Does anyone know why in my datatable, sorting doesn't seem to work on ints? https://i.gyazo.com/ffe6a8da453ffd77e505a6c7f5b8eda6.mp4

Unreal Engine bug? 😦

[sudden nimbus]

looks correct to me, if the field is a string

[untold fossil]

the field is an int

[sudden nimbus]

so it's not that it's not working

it's that it's sorting it's string representation

[untold fossil]

well shouldn't ints be sorting from small to big and vice versa?

[sudden nimbus]

think of these like strings not numbers

[untold fossil]

hmmm ok but why is there a sort button then? 🤔

[sudden nimbus]

if they are strings, it's sorting correctly. I'm not saying thats desirable for you but that's what's happening

[untold fossil]

Is there a way to change it so it sorts properly?

As in from small to big and vice versa?

[sudden nimbus]

good question

[untold fossil]

I could probably export the datatable to excel and sort it properly there, but bit tedious

[gentle urchin]

Less than the alternative

In-editor sucks 😅

[untold fossil]

yeah that works, I'll just make the entire DB using excel

in-editor indeed sucks, full agree lol

[lost sky]

Why can't I give a static mesh to my blueprint actor?

[floral quarry]

I've dealt with velocity based clipping, ad there are a few ways to fix it

[barren tangle]

Yes?

[floral quarry]

One is you need to make a way bigger collision box on your object

second is you change the FPS of the object to natively higher than the FPS of your game

so it'll check between ticks

Other is, depending on the size and length of the object-- say you got an arrow. You want the collision box to be at least a 1/4 longer than the object

There are other things like continous collission

OR set up your detection through a function instead of through the tick, because a function event is more reliable because you can set up the time between checks

[barren tangle]

But is it the collision the issue or the lack of collision because of the speed

I extend my collision box

[floral quarry]

its the speed

[barren tangle]

And notice the collision is inside the box

[floral quarry]

If you're going too fast and using event tick, it'll only check on that tick

So

If the object is going too fast, and moves too much bewteen ticks, you need to set up a function that checks twice as much as your FPS
like

If you make a function event and set it to loop and set the timer to .0167(120FPS) and set your games play rate to 60, it'll stop having issues with detection. Unless you're going excessively fast

but I was able to set up my vehicles to collisde properly going at 50,000 UE units without issues.

BUt

you have to set up your worlds collision to continuous. Not only your character or object in question

[barren tangle]

So there is an impact on the performance? How do you set up the world collision to continuous?

[floral quarry]

A small impact, depending on how you perform the checks

Event ticks take more performance than event functions

and

a event function can be set to check only when needed. Event tick checks all the time until the object is destroyed

[crimson prawn]

hello, I would like to invert the turn rotation of my character to see his face. Can someone help me please?

[floral quarry]

use the controller control rotation node

[barren tangle]

ok thanks i will try to change my approach

[floral quarry]

If it doesn't work I can probably show you, later

[barren tangle]

i think i will manually set the limite of my world position

[crimson prawn]

do you mean "Use Controller Desired Rotation"?

[floral quarry]

Yes

SOrry im terrible with names

[crimson prawn]

by cheking it changes nothing :/

[lost sky]

Why does this event not work for me?

[floral quarry]

Does your character have a movement componenet?

[crimson prawn]

sure

[floral quarry]

ok

Does it have a boom and a camera?

[crimson prawn]

yes

[floral quarry]

I think you can check in the boom to do it directly

[maiden wadi]

This actor has not had input enabled.

[reef tinsel]

can anyone confirm without a doubt if blueprints suffer a performance impact from having many calls to the same variable or not?

sometimes having just one call makes too much spaghetti

[maiden wadi]

They do not, sometimes. It's a BP thing with how it executes nodes. Sec

[reef tinsel]

right, they're pointers, thanks

[maiden wadi]

Pointers?

[reef tinsel]

a reference to the variable, the nodes aren't holding a value

[maiden wadi]

Still, this might showcase better how BP handles that. These aren't variables, but variable access works the same as a pure node.

[reef tinsel]

ahh, good to know. got it

so in this case, the + operators are like pure functions and it takes the original value on the second call

[lost sky]

How can I enable it?

[lost sky]

This still doesnt work, I also tried on the controller

[maiden wadi]

Correct. At least per executed node (node connected with white lines). Basically execution runs the executed node. Before it runs it's logic it will go through each of it's parameters and call connected pins, which will call their input pins. But if the node has already ran for that specific executed node it will just retrieve a cached value since it'll be the same value anyhow. It's neat to learn how BP works like that because it'll save you a ton of performance costs. Specially when it comes to things like a pure node returning an array and using it in a ForEach loop, only to realize that the thing getting the array is being ran every loop iteration.

[maiden wadi]

You didn't pass the PlayerController you want to enable the input for.

[tiny monolith]

**[HELP]**I'm trying to scroll down by holding down the button in the combobox, I wrote the necessary code, but it doesn't work on the phone, it doesn't see the press button of the button, I opened the setting from the project settings, I opened the touch click setting, but it doesn't work, I can't get interaction on the buttons I tried touch input, it doesn't work in the combobox, it doesn't work in other places, it works in other places, I tried to write into the button, it didn't work again, what to do to make it work on the phone

[lost sky]

https://youtu.be/KE_8OwmHY-A Can you please look at minute 8:17 ?
This guy doesn't seem to need to enable inputs yet it works

[maiden wadi]

That is in his possessed pawn.

[lost sky]

And I can't figure out how to reference the controller blueprint

[maiden wadi]

It has input enabled from possession.

[lost sky]

I'm confused

Why do I not have possession?

[maiden wadi]

Because what you created isn't a pawn.

[floral quarry]

You need to set it up in the begin play of your character

Otherwise

you can use the Debug key

Those work without input

[lost sky]

The video is also an Actor
but I even tried on pawn, it didnt work still

[lost sky]

this is pawn

[maiden wadi]

Eh?

[lost sky]

what do you mean?

[floral quarry]

the "debug key [instert key name here] node

it's for testing

[maiden wadi]

Debug keys still require input enabled.

[floral quarry]

Does it?

[maiden wadi]

They do not require an applied context mapping. But they do require the actor to have input enabled.

[floral quarry]

Maybe set up enhanced inputs

[lost sky]

Okay but pawns don't require enabling right?
why does it not work on my pawn then?

[maiden wadi]

Is this blueprint specified as your player character in your GameMode?

[floral quarry]

^

[maiden wadi]

Pawns require possession to have input enabled. Consider something as simple as a character and a car. You don't want inputs in the character when you possess a car. Likewise when you exit the car and repossess the character, you don't want the car to drive off when you hold W expecting to run. Thus possession enables and disables input based on which pawn your playercontroller is currently possessing.

Well, require is a bad phrasing. They don't "require" it. But they do it automatically.

[lost sky]

I need to watch some videos explaining this stuff
there's alot i dont know

[maiden wadi]

#GameDevLife

[lost sky]

the unreal learning library is so overwhelming though
where do you recommend I start?

Is this the place to start?

[warm fern]

Is Blueprint composition the wrong path to be taking in Unreal? I am a new Unity convert and have been approaching Unreal designs using my Unity understanding, but have hit some walls I don't understand. I have built out two Blueprints; one for a "Collection Zone" that holds references to anything that overlaps it with a specific configurable component and one for a "Hand" that the "Collection Zone" would be attached to. I then created two "Player" Blueprints and added the "Hand" Blueprint to both as a child then added the "Collection Zone" Blueprint to each underneath the "Hand" Blueprint instance. In the "Player" Blueprints with the "Hand" and "Collection Zone" Blueprint instance children I cannot change any variables like the "Handedness" value on the "Hand" or the "Collection Zone" class to check for. Any pointers on how something like this would be done the "Unreal Way" (and not have to manually setup everything in each player)? Side Note: Both the "Collection Zone" and "Hand" Blueprints have Actor Components on them for their functionality.

[lost sky]

Or this?

[maiden wadi]

Honestly that is a loaded question no one can really answer. Many many factors. Personally I recommend just finding some shitty tutorial to follow for a couple days. Something with a bunch of short 30min sessions that has 10-30 in them. Some "Build a survival game" or "Build a city builder" thing. Follow them. Do exactly as they do. Immerse yourself in the engine. When you're done. Go back through it step by step and do it again but stop and pause to learn why things are being done. You have a lot of concepts to learn still and no single guide will cover them all.

[maiden wadi]

For starts, a single player character blueprint. You can spawn multiple instances of this, one for each player.

If you cannot edit the properties of the component within it's actor tree, then the property in it's initial BP needs to be marked as InstanceEditable in it's own class.

[barren tangle]

does the projectil movement component affect the collision of the actor??

[maiden wadi]

Affect, no. All any movement component does is sweep the root component of the actor.

[barren tangle]

ok so i had a root scene that was not good with a sphere. i guess there was an issue like that. i remve the scene and only keep the static mesh and it's ok

[slender mural]

there should be a node for this

[maiden wadi]

For what?

[slender mural]

checking against table rowstruct

[maiden wadi]

Not really sure there's a big point for it? You're already checking it with the GetDataTableRow.

[slender mural]

unnecessarily checking against the hashmap to do so.

Data table row handles are a very neat feature, and would be worth fleshing out

[maiden wadi]

You can check if the Datatable is not null and that the FName is not "None". There's a helper for that in C++. But it won't specifically tell you if that row actually exists in that datatable without checking it same as GetDataTableRow does.

[slender mural]

I can make a custom thunk in c++ in an hour that will do exactly what I want. I'm mearly voicing an oppinion.

[compact fable]

Does anyone know much about collisions? I am attaching an actor to my actor and setting that actors collision to query only but it's affecting the character movement as if it still have collision on

[bold torrent]

In blueprints, how would you move a primitive component around (with Set World Location etc) while keeping world collisions enabled?
The Sweep boolean works, but once a collision is detected it doesn't update until the collision is lifted

[gentle urchin]

Lifted as in backtrack a bit?

[bold torrent]

I'm setting an objects location with the crosshair, and if I drag it into the ground it registers the collision when Sweep is true, but if I drag to the left or right from there nothing happens, until I lift the crosshair up from the ground

With Sweep off, the object just clips halfway through objects around it

[gentle urchin]

Couldnt you offset it with the sweep result ?

If thats the behaviour you're looking for..

[bold torrent]

You are probably correct, I was just about to test it out 😄
When a collision is detected = Offset the primitive by a unit or something to keep it moving

[gentle urchin]

I think you can figure out penetration debt from the sweep aswell ?

[bold torrent]

Probably, but I don't think I need it for what I'm doing. As long as the object keeps moving alongside the surface when the target vector is penetrating another object I will have achieved the intended behavior I'm looking for

[graceful kite]

Sigh. New to Unreal 5, the whole enhanced input is driving me crazy. I've used the old methods before but something as simple as moving a camera doesn't want to click for me. Yet to find a tutorial that just starts from scratch with oet yet either, even trying to reverse engineer the premade projects hasn't gotten me far

[slender mural]

Input-Action Object == Actions as you would define them in the project settings.
Input-Mapping-Context Object replaces that entire menu

So you need to Add->Input->InputAction for every single key-press/Event/input action you need.
MoveForward, MoveRight, Jump, ect...
Bind all of them up in an Input-Mapping-Context

*Enhanced Input Local Player Subsystem needs to be called from a player controller

[thin panther]

Often, a crash

It means something went wrong, bad

[fallow osprey]

Nothing, if it's a shipping package

[burnt badger]

anyone know any tutorials to add button panning to increments of say 90 to rotate camera around person or could help me with code to do what i want it to do?

[fossil wharf]

Hey.

I made an animation. My goal is to play animation on button press

The problem is with the first one

I dont know how to freeze it

At the last frame

[slender mural]

I think if you want to freeze it like IA->press hold IA->release you would need to create a state machine.

[fossil wharf]

What for?

I found something about notify event

[slender mural]

Animation montages play single fire animations. If you want to hold a state you probably want to blend a pose in your animation blueprint

Notify events are events that fire in your animation BP. They are triggered from animation montages

[fossil wharf]

Ah

[slender mural]

might try this actually

these are in Anim bp

there is also this event in the character

[copper chasm]

If I were doing something like D&D stats, and I wanted to make each stat its own struct so I could modify it and track those modifications - could I slap all those structs into an object and put them on the character as a component?

I'm pretty sure I could and I could test quickly, but I like asking first so I don't feel disappointed when I dumb it up 😄

[slender mural]

Arn't D&D stats as simple as an integer value?

[copper chasm]

Well, the stats themselves sure - but what if your item gives a bonus, a buff gives a bonus, whatever - you could probably stick those in as they go but I'd like to streamline that calculation

[sudden monolith]

how do I change a widget size in the blueprints?

[copper chasm]

size box, set the width and height as variables

[slender mural]

buffs have a lifetime, and items are equipable.

[copper chasm]

ok

[slender mural]

In my mind your stat struct would look like {BaseValue=10,ItemValue=0,BuffValue=1}

[sudden monolith]

I cant drag it into the text?

[copper chasm]

right click on the text, wrap with -> size box

[slender mural]

and then getStat(ID){return BaseValue+ItemValue+BuffValue}

[sudden monolith]

and how can i set the textsize wiht that?

[copper chasm]

I guess my question was more about the component aspect, as I haven't used them very often - I know how I'm setting up the stats and whatnot, but instead of putting them in as variables directly on the character base bp, I could make an object that has them, and add that object to the character base so I can call on those structs as needed instead of having them sit in the variables list

[slender mural]

Components are good and useful lol. the lend towards a modular design.

It doesn't really matter where you put the logic

[copper chasm]

but like, that is how that works, right? info in object, add object as component to character

i guess I was looking for a very specific very dumb answer lol

My blueprints were messy as sin so I'm recreating them all in a new project and trying to make it more clean, now that i know it works

[fossil wharf]

@slender mural

this might work

since fuckyoustop is like reversed animation

[slender mural]

yea that's workable

[fossil wharf]

[copper chasm]

on the text object itself, in the details panel - this might be a video you need to watch tbh, I don't have any widgets available to screenshot

[slender mural]

probably not very scalable

[fossil wharf]

i mean, there's not gonna be many ia -> play montages anyway

[slender mural]

sounds like a situation of if it works it works

[fossil wharf]

But there's a problem.

Animation doesn't play till the end, really. It's just playing to the half of all frames

In such flow

[slender mural]

bro learn how the Notifies work

[fossil wharf]

Like here xD

Even though it's full MM_Idle2

It doesnt play till the end ;-(

Ah maybe it's because of the blending out or something

[slender mural]

you can create an animation sequence from a single pose.

and then add it into your state machine

or you can do the montage thing the way you have it setup, add a notify, and see if it spits out the right name

[fossil wharf]

This works really good

I just turned off blend out from first montage

[slender mural]

If you do it that way I would add an interface for the AnimBP add a three functions called Pose begin, PoseHold, and PoseEnd

select by enum, and utalize that pause montage function I showed earlier

that way you can hold the pose at any arbitrary location

[languid cliff]

So there is string to color
and it have a flag for returning false if it was unable to identify the color
there should then be a list of named colors that unreal use to check that against,

do anyone know where I can find that list of named colors?

[slender mural]

scratch that I forgot you can add sections

[balmy viper]

When my character hits a trigger it starts simulating ragdoll physics, which works, but it also seems to get a large impulse applied. Any ideas?

[languid cliff]

oh i think i understood it wrong, saw it and assumed that "red" "black" "green" type sting would be used

[slender mural]

yea, that doesn't seem to be the case

[languid cliff]

this looks to take in the actual rgb as text and parse it

[azure walrus]

Hello, the pedestrian is supposed to run away when a gunshot is fired, but currently he runs away at every sound. I wanted to control this via a report noise event with the tag Gushot but unfortunately the sound is not filtered - any ideas?

[lunar sleet]

🤔 maybe you can use an EQS test to filter the sounds, haven’t tried it tho. Use #gameplay-ai for these questions, there’s people there with more experience

[fossil wharf]

Problem here is that I can fire this in the air

And the character freezes in air as long as I hold the button xD

The idea is to check first if the character is basically idle or something

or like in the state of being on floor

if that makes sense

[lunar sleet]

There’s a built-in isFalling Boolean that goes True as soon as your char is in the air. Use it.

[fossil wharf]

Thanks

Works great

Now the replication part

[blissful moat]

Hello, is there a way to create blueprints in my level that is separate from the Level Blueprint? I want to create a manager to assist my AI in the level. The idea is that the AI checks if a manager is present in the level and then spawns one if there isn't one. I know I can do it by spawning an actor in the level but that feels a bit hacky. Is there a better and cleaner way to do this?

[iron idol]

I have a variable on my characters for spells to keep track of what spells they have. When I remove a spell from the array variable on the character and wipe save, the character has spells I didnt assign to it. Does anyone know if this could be because the array is a class reference as opposed to an object reference?

[hollow yacht]

Does anybody know how I can reference this actor to set up a texture/material update?

The issue I'm running into is that this object isn't treated as a traditional mesh object and so the Dynamic Material Instance method (which seems to be the most common thing I find online) doesn't work for this particular object.

[brazen stirrup]

hey guys for a ledge detection system i was thinking of doing a sphere trace, if it hits something then do it again, and if it still hits something hit again until there is nothing that the sphere tracec

would this be performance heavy if its done every 3-5 seconds based on the ability cooldown?

I should rephrase my question

I meant edge detection, so if the player is aiming for a edge of a object, they are teleported to the objects surface instead

kinda like a aim assist

used in games like aragami 2 and spiderman ps4 as well as sekiro

[balmy viper]

@outer echo "This also leads me to believe that the event on tick is also working correctly." - Don't be led to believe ... put in a PrintString in the OnTick. If you see 50ish messages a second, you know that code's being called

[outer echo]

I'll do that for sure

[balmy viper]

Eliminate 1 unknown at a time

[outer echo]

Thanks for the input

[balmy viper]

np

[outer echo]

I'm testing rn where or not manually changing the angle on the make rotator node is actually reflecting in game

[outer echo]

also, I really do appreciate the swiftness and cordiality of your response. I wasn't expecting that and was expecting people to be much more difficult to work with

[balmy viper]

some people are, but there are also more ... understanding people ... we are all on the same road, at different points along it

Did you add the tracewrite? What happened?

[outer echo]

I'm testing the printstring now. I'm kinda split attention wise between multiple things (kids) and this so it takes a minute

[brazen stirrup]

ok so here is what I came up with:

I think the sphere is only picking up the object once, even if its set to overlap

[balmy viper]

What happened to all the other nodes in the Tick?

[outer echo]

oh, I disconnected them for simplicities sake

[balmy viper]

up to you ... didn't have to do that ... just insert a print string between the Tick and your first node

So this Event Tick is in the event graph, right?

[outer echo]

yes, it is

[brazen stirrup]

what if I trace one upwards, then one inwards to see if the place is indeed a surface

[balmy viper]

have you dragged an instance of this blueprint into your scene?

[fossil wharf]

@lunar sleet alright, replication works

[brazen stirrup]

or am I just reinvinting the function here

[fossil wharf]

also made the animation so i know the workflow now etc

great :-D

[outer echo]

So, embarassingly, I can't get the scene to function at all. When I hit play, even before I made any changes, the whole thing stops responding, so I've been testing it by deploying the mod and running the game. However, all the other changes I've made work flawlessly

[balmy viper]

It freezes on Play-In-Editor?

[outer echo]

Oh, well, it didn't this time, I just see a black screen and hear music. I'm using a world that someone else made for the mod that I'm now expanding upon

[brazen stirrup]

nvm figured it out

with one sphere trace

[balmy viper]

What's the game and what's the mod?

[outer echo]

Mechwarrior 5 mercinaries, mechwarriorvr

[balmy viper]

Well I don't know ... you may be reaching a little outside the sphere of your current capabilities trying to mod a game like that. Debugging a situation like you've described, with black screens / freezing etc ... is probably a little beyond the scope of this forum. If it were a game you'd made, it would be a lot easier

with someone else's project it could be anything going wrong

[outer echo]

I gotcha, I'll keep chipping away and see what's up. I've moddified another blueprint in the same mod and deployed it and it works flawlessly, so I'm optimistic

[past hull]

hello, how to check if a reference is empty or not ? I tried with is valid but it doesnt seem to work, my function here always goes to the print string function.
The function should simply check wich weapon slot is available and return 1 for primary, 2 for secondary, or 0 if both are referancing a weapon.
the final goal is to have a 2 weapon system for my fps game

[iron idol]

make a print string with the name before it fires

if it gets the name then it understands the reference

[past hull]

I am dumb, I inverted true and false with both branch node for primary and secondary

thank you ahah

[iron idol]

no problem. happens to the best of us. Glad you figured it out.

I have an array variable on my characters that tells the game what spells they have. I'm trying to add a spell in game, though a new spell is added, it doesnt seem to recognize the spell and its blank. Could someone tell me what I'm doing wrong here

[orchid loom]

sorry, I follow a tutorial in youtube, is from lisowi the inventory tutorial, and i want to ask for a method to only allow certain type of item to enter the hotbar, can someone help me pls?

[balmy viper]

also there are two versions of IsValid ... one is just a boolean .. the other one has a built-in execute node

can save a bit of space / less nodes

[chilly hazel]

Est qu'il y a des gens qui parlent français ici

[unborn orchid]

I must be missing something really basic: Can anyone tell me why my line trace + niagara beam is not ending when it hits something given the logic that I've set up here?

[lunar sleet]

For starters make sure your param name is exactly precise no extra spaces or whatnot. Then print the actual impact and see if you actually get what you want

[unborn orchid]

Param name is correct!

[chilly hazel]

S'il vous plaît please si oui on peut m'aider a comprendre s'il vous plaît

[unborn orchid]

right so for some reason the impact point does not change which is confusing given the fact im moving the laser around the world.

[lunar sleet]

Now you know what to debug

Also your line trace has an actual draw

Set it to duration or permanent to visually debug

[unborn orchid]

yep that doesnt look right

I guess I am missunderstanding how to set the vector paramater node because if I break the execution line before that, it works exactly as intended, the debug draw and the actual beam are right on top of each other.

[reef totem]

any better way to do this to allow the bucket to properly collide with physical cubes?

[unborn orchid]

So apparently if I split the pins of impact point and take only the x value of that vector, the beam points into the intended direction agian but it still goes right through any object even though the impact point x is now the new beam end. I am not sure where I am going wrong right now.

[tulip anvil]

are you locking the cube in place somehow so it doesn't bounce out? in my testing a physics actor normally just stays on top of a moving platform.
alternatively you could put in a box collision and move all actors in the collision along with the basket.

[reef totem]

no im not locking anything, just for some reason it doesnt move up

im going to try a different aproach and attach the basket with a socket/constraint

currently its just a staticmesh child to the main body

[dawn gazelle]

I'm not sure if this is the answer, but try changing the tick group on the timeline to during physics or post physics.

[reef totem]

ill give it a try thanks

[crimson prawn]

Hello Is there an event when a controller is just plugged in?

[reef totem]

sadly did not work :/

[unborn orchid]

Okay after some further experimentation, I simply do not understand why impact point X is always the same even though the line trace is moving. Anyone has an idea why that might be?

[tulip anvil]

if you just drive around without moving the basket up/down it stays in without glitching through and freely moves around within the basket?

[reef totem]

yes

[tulip anvil]

that is very odd

yeh i got nothing, because if it was the case that it simply doesn't detect the collisions of ur child mesh properly it would fall out when moving too, and moving it up should detect the collisions phasing into eachother and then pushing back out.
if changing it to a socketed mesh works idk if i'd be more or less confused.

[reef totem]

here is the hierarchy if that helps

[reef totem]

im really inexperinced with socketed meshes. So things are NOT* going great with that lol

[mental trellis]

You should probably ask in #multiplayer

Oh. You did!

[unborn orchid]

Okay so I figured out that the impact point was being detected INSIIDE the mesh of my enemy. I fixed that with the Actors to ignore input on the line trace by channel node.

However, this logic still does not seem do be shortening my niagara beam.

I can see that the impact point is being correctly detected now but me setting the vector parameter x value of the niagara system does not set the beams end point correctly. If anyone has a pointer I'd really appreciate it!

[tulip anvil]

try hooking up Y and Z as well

[unborn orchid]

that just seems to offset the entire beam in a really weird way instead of shortening it.

I think I may be missunderstanding how the paramater node works.

[mental trellis]

Have you tried taking the hit location away from the start location and getting the length of that vector?

And then using that as your X.

I'm assuming X is "forward" for the laser.

[unborn orchid]

it is.

[unborn orchid]

Will try that out now!

Okay so that is definitely working somewhat

But it is also creating some really wonky behavior

this is the logic I am using now.

[mental trellis]

Don't just use X.

Use the entire vector...

What you want to do is, on the output of that - node, use a vector length node.

And plug the result of that into your X parameter.

And use the entire vector, not just the length of X.

[median kiln]

Thanks lol! Ill delete this one

[unborn orchid]

That worked perfectly, thanks a bunch, I've been sitting on this for a while now!

I assumed that if I just plug the impact point from the break hit into the x param of my set vector param node it would work.

[mental trellis]

[bitter folio]

I have a health system and I'm wanting to increase max health without messing with the current HP How may I do that? (This is under a Pickup) Im pretty new and im trying to learn, any help is apricated!!

[rugged wigeon]

You are currently calling Set Health

You want to call Set Max Health

[bitter folio]

Right but how do I make the Varible Max Health actually effect the max HP?

[rugged wigeon]

max health should be the max hp. you might be meaning to ask how do you make the max health get reflected in the game ui?

[bitter folio]

so what I have done is create a variable in ThirdPersonCharacter called Max Health and set it as a Float. Then I went into my pick up-able and set what's in the image above. I also have a Debug Keybind to read current Health, So I pick up the max Hp pick up then heal my self using a healing box I made, yet the hp stays at 100 and does not go to 110

Id assume its bc I need to do something more with the variable?

Here is what it looks like currently

Do I need to set Max Health as the Health variable's max Healh?

[tulip anvil]

how are you increasing the health when healing?

[bitter folio]

yeah, I just realized I put a cap in the healing box my bad. Im figuring out how to cap it to the max hp elsewhere rn

[tulip anvil]

when healing compare health+heal amount to max health, if (health+heal amount) > max health set health to max health.

@bitter folio

[bitter folio]

Thank you

Thank you both for your help, its all working!

[dawn gazelle]

Could just use a clamp node to always clamp the value of health to max health

[bitter folio]

had no idea that was a thing

How may make it so when this gives me health it updates my health bar?

[frosty heron]

You can have widget listen to the change using event dispatcher

Btw make your nodes less of a spaghetti, a few more nodes and it will be unreadable

[bitter folio]

Yeah sorry working on it, just started like 4 days ago with a friend, pretty enjoyable experience so far though

[granite dome]

a item i want my character to place only show up in a certain hieght and i dont know how to fix

[obtuse kiln]

I can understand my own spaghetti fine even when it's true chaos, but I should probably still get better about commenting just so I can understand what the hell is going on when I'm plugging in something that someone else came up with, from a tutorial or forum post in 2015 or whatever...

also should probably start setting variables and using them instead of dragging whatever object or float off an event like ten times...

[frosty heron]

Just don't make spaghetti

Use reroute node, make it pretty

[maiden wadi]

Functions help a lot with this, if you don't need latent nodes.

[rugged wigeon]

if you don't need something outside the scope of an event, you don't want to make it a variable.

You maybe want to make it a local variable in a function.

[undone bluff]

yea use lots of functions

you don't even need to make local variables for inputs

you can place them as get nodes as is

optimally you avoid wires long enough to even need a reroute

[bitter folio]

having trouble figuring out how to do this honestly 😅

[faint pasture]

Save PercentFull = HP / Max
Update max
set HP = Max * PercentFull

[bitter folio]

I have that understood, the issue is updating it to my widget when healed

[faint pasture]

When does your health bar update normally?

[bitter folio]

at the moment on damage

[faint pasture]

Keep that same energy

negative damage is healing

bam, done

[bitter folio]

I had that thought tbh was hesitent to do it bc I had no idea if that was a no no xD

[faint pasture]

I always prefer to keep things consistent

The only thing that makes it feel weird is that the node is called Damage

if it was called ModifyHP then it'd be a no brainer

but I'd do it that way

why have 2 ways to change HP and trigger a UI update when you could have 1

[bitter folio]

well wait, maybe im just brain fried atm but im not using damage I dont think

just subtracting health

Im seriously overthinking this 😅

[faint pasture]

What happens when you subtract a negative number?

That looks fine, but you would instead want to use a clamp instead of that branch

Damage -> HP = Clamp(HP - Damage, 0, MaxHP) -> update bar -> if HP nearly equal 0 or whatever your test is -> kill self

[bitter folio]

yeah it still don't update it, I have the blueprints for "healing" in the blueprint for my healing box, I think I need to just cast what happens there to my health bar widget, But im soo lost on how to do it exactly, ive gotten a few responses but im not sure how to do it as I haven't used some of the things they are telling me to use before

[bitter folio]

thank you

[faint pasture]

Just have healing box do damage with a negative number

[bitter folio]

I think it is

[little orchid]

Forgive me I'm somewhat of a noob, but I need to know how do you call the play or reverse from a timeline, that need to be connected to a branch so for example from the true branch you're going to call Reverse, and from false you're going to call play? Nvm, figured it out..

[faint pasture]

I mean literally call the add damage node

don't modify hp

[bitter folio]

ah

[faint pasture]

then it'll go through your current damage handling code, just with a healing number

[bitter folio]

Thank you so much, Have a wonderful day 🙏

Though now if it ticks 2x it kills my character

[flat warren]

Beginner here, anyone know how to make this rotation happen more gradually? I tried a timeline but couldn't get it working. Any tips would be appreciated

[frosty heron]

Timeline for fixed length,
Interpolate with tick if no fixed length

that's your only option

[flat warren]

how do I get the return value of Z to affect the timeline. Its currently rotating an npc

[frosty heron]

You use timeline when you need to get from point A to point B at SPECIFIC lenght(time)

is that the goal here?

meaning, the start and the end rotation is already pre-determined before the timeline start

changing them on the fly will give different result

use Interpolation on tick if you are not trying to get to A to B in X seconds

[bitter folio]

Anyone have an idea to why giving my self negitive damage on the second tick it kills my character instead of healing it?

[flat warren]

Sorry I am a bit confused, Ive got the rotation it needs to get to (which is the find look rotation), and I just want to rotate the npc to that direction

[frosty heron]

still haven't answer the question if that action needs to be done in specific time length or not

if you just need to look from A to B at constant speed, use interpolation

if fixed time (e.g. you want it to go from A to B in X seconds) then use timeline

I can't suggest to use timeline or to interpolate on tick unless you tell me what you want

[flat warren]

It doesnt need to be done in a specific length of time, but also could be. Whichever is easiest. I just dont understand how I use the values when using a timeline, the only input is "new time"

[frosty heron]

It's not about easiest but using the right tool

I'm just repeating my self over and over now

Timeline only works if the length are specified. Length being the time in seconds

Any other use case interpolate on tick

[flat warren]

How would I use the timeline, because the changing value is predetermined right? I need to be able to input my end point

Thank you for your help

[frosty heron]

Set the start rotation and the end rotation b4 you execute the timeline

Start rotation being the current rotation of the actor

End rotation would be the end rotation ( so the look at rotation ) in your case

Have a go at that then post your code @flat warren

[flat warren]

@frosty heron I still don't understand how to connect them

[frosty heron]

You need to cache them as variable

Have a start and end rotation variable

Since you just care about the z you can use float here

Call it start z rotation and make another variable called end z rotation

[gentle urchin]

Tick is more appropriate here imo

With an optional gate if its conditional

[bitter folio]

So this is a pickup that increases the max hp of the player, how may I make it so it also updates the health progress bar to show?

[dawn gazelle]

Your UI should be trying to read its values from the relevant actor that has the health, or listen to event dispatchers that you would call when the value changes so that the UI can just update itself.

[bitter folio]

Not sure how to do that exactly

At the moment it only updates off damage I think

[orchid loom]

sorry, I follow a tutorial in youtube, is from lisowi the inventory tutorial, and i want to ask for a method to only allow certain type of item to enter the hotbar, can someone help me pls?

[frosty heron]

Look up blueprint communication video by matthew and some material/video on event dispatchers

[bitter folio]

Thank you

[frosty heron]

You want the widget to listen to event being broadcaster when the hp is changed

[gentle urchin]

And ypu want to create a method for changing hp, so you always call the correct stuff when it changes 🙂

[bitter folio]

"Look up blueprint communication video by matthew" Am I suppose to follow this? it seems kinda outdated, maybe My thing is set up poor but I cant do some things he does

[frosty heron]

the point is to understand how to communicate between different blueprints. It's not outdated, regardless of the date, the basic principle of OOP remain the same.

[bitter folio]

The one by Matthew is clearing up some things

[frosty heron]

for what you are doing, event dispatcher will do wonder here, but you will struggle to use it if you don't know how to communicate between different blueprint classes

[bitter folio]

I hear ya, I know this is beyond basic lol It'll probs take me a little for understand this

thank you for helping me

[bitter folio]

I had somthing funky going on, its all good now sorry

[orchid loom]

how i can get a local variable in other blueprint?

[marble tusk]

so does this Download Image node not support webp? Or am I missing something because this always fails

I did try directly pasting a working url into the pin too

I'm assuming it doesn't support webp, but I don't need it to since I replaced webp with png and it works

It's still odd how Discord uses webp for avatars, emoji and all kinds of stuff, yet you can't send webp images in chat

Luckily they do have png versions

[raw kite]

How do I get a blueprint to update in the editor when an object it's referencing is tweaked?

In my case, I want to move an object in my blueprint using the transforms of a camera, which I'm referencing using a Cine Camera Actor object varaible. But the blueprint doesn't trigger when the reference camera is moved around, only when I directly edit variables using the details panel. I'm using a construction script, but it looks like none of the default triggers in the event graph would be helpful either, updating only during play (which doesn't help me in the editor).

Hi, how bad is using get all actors with interface? I've got an ability on my character that when active I want to send a message out to other actors so they can do their own stuff if the ability is active or not.. is it best to use an interface for this or event dispatchers? i'm trying to remove some dependencies because right now im making all the changes to these other actors from my character class when really the actors should be doing them themselves

[mental trellis]

Get all actors is just bad in general.

I'm not sure if interfaces are hash bucketed like regular classes, though.

[prime stump]

What's the alternative to using get all actors, if you need to get all the actors? and how's best to do this kinda thing, i wanna send the message out that the ability is active so these other actors can react to it without having everything referenced making them all dependent on eachother which i dont think they should be

[mental trellis]

You may actually have a good use case for get all actors of class. It's rare people actually need all the actors of a certain class and just abuse it.

"get all actors of class for my main character" 👍

[thin panther]

This honestly sounds like a thing for a dispatcher.

If you want to broadcast an event. If you're willing to go third party, there's also the gameplay message router, which allows communication between unrelated actors

[prime stump]

So the dispatcher would go on my character class and call it when the ability is active, but then wouldn't every actor that needs to know about it need to be directly referencing my character class to bind to the dispatcher? i dont mind going third party either lol as long as it can do the things i want it too 😂

[thin panther]

Sure, however a direct ref to the character is a lot better than the character directly reffing everything else.

Your character will always pretty much be loaded, the other thinfs won't be

Though I really don't know why gameplay message router isn't a core thing in the engine 😔

Your method will work, btw, I'm just giving alternatives

[fiery swallow]

btw it's totally fine to have direct references to base classes, you could put the event dispatcher there and still call it on the actual actor that activated the ability

that only matters if youplan to go with his alternate method

[prime stump]

Thats a good point actually i didn't think of it that way.. yeah i tried the interface method n it did work but i just wanna figure out what's the best method to use with performance in mind and trying to keep dependencies down

[jaunty badge]

hi there
how can I change things then, the sphere don't rotate around the cube even if the cube moves fast?
the relationship between them is a simple physic constraint without any change.
sphere mass is too high but it seems that gravity could not handle it.
I want to sphere to be under my cube all the time. think that a helicopter is flying(cube) and moving some object(sphere).
would you help me?

[tawdry walrus]

I didn't use it before but I think there are variables in the physic constraint component

in the details panel

[jaunty badge]

there are some and i have changed them but did not get the result i wanted

[past hull]

hello,
How can I get the object reference from the "Weapon to spawn" Class reference please ? On the second image it is used in the spawn actor node and it returns the object. But what If I want to object before spawning it ?

[tawdry walrus]

try to change the Angular Limits in the physics constraint component

[iron idol]

I seem to not have the new ue5 mannequin in my 5.4.2 project. I cant seem to do the in engine animation. Anyone have an idea as to how I might fix this?

[mental trellis]

You may need to expand on what a "basic horror character" is.

[jaunty badge]

the problem is sometimes the helicopter is in front of the object and I want to catch it so I should set the angular limit to at least 90 degrees. if I do it can rotate as well too! if I don't it won't go under my helicopter
idk what should i do
maybe i should set the location in Tick based on the helicopter location

[bitter folio]

Right so im trying to learn event dispatchers, I have an asset called HealthPickup and im trying to just play a sound for now when ever the character goes over it. This is what I have atm but it wont do anything, if anyone knows why that would be amazing

[vernal lotus]

what on earth is this??????

how does this work?

I'm just stunned rn

[gentle urchin]

looks about right, tried calling the delegate again?

[vernal lotus]

I need someone to tell I'm not the only one seeing this

[bitter folio]

wdym

[gentle urchin]

the binding is setup on beginplay, so.-. are you sure the delegate is called after beginplay ?

[bitter folio]

oh, how might I go about fixing that?

[gentle urchin]

well.. what is triggering your on overlap ?

if you had to walk somehwere for it to trigger, then you'd know it'd be after beginplay

you can add print strings at both places, and see which order they show up in

the lower one came first (so add context to the string being printed, so you know who's who)

[bitter folio]

Ohhhh that clears alot up, let me try to see if I can implement that

[bitter folio]

So as soon as I start the level The event BeginPlay one is firing instantly, how could I make this fire when I overlap with the pickup? Sorry I know in the scheme of things this is super beginner

[gentle urchin]

you want to bind to the delegate as soon as possible usually

Well, you have the pickup right?

[bitter folio]

correct

[gentle urchin]

which triggers some overlap and interaction with the character?

Hopefully through a public function ?

[bitter folio]

When player overlaps with it, the max health is increased

[gentle urchin]

so

this is not a public method

[bitter folio]

ah

[gentle urchin]

you should encapsulate the logic that belongs to the character inside the character bp

while externals may call exposed functions (public ones) on your character, you shouldn't let them manipulate internal variables!

Reason being exactly this, in your example;
You want several things to happen when MaxHP Increases on the character

if you were to manipulate this externally, you'd need to make sure you update every single thing you expect to be updated, when this variable changes

While if you wrap it up in a function inside the character, it's done, forever!

[bitter folio]

Ohhh

[gentle urchin]

and if you have a bug, or wanna expand it (call extra delegates, start auto regen or whatever), you only have to fix in one place.

[bitter folio]

I see my bad, i've been using tutorials online to figure out somthings then applying what I think I need to make things work, had no clue it should be like that

[gentle urchin]

While they show you some ropes, they usually bring along bad practices

you may still follow them to get a grasp, but I'd at the very least suggest trying to always consider how the logic could be encapsulated into it's owning class

after all, thats why we have all these classes

[bitter folio]

So, should I make a event dispatcher to call the max hp being updated?

[gentle urchin]

separation of concerns

[bitter folio]

At the moment my Hp Updates inside the Character off of damage

[gentle urchin]

In this case you want to :

• Create a function for manipulating MaxHP in the BP_ThirsPersonCharacter
• Inside the function , you manipulate the MaxHP variable, and call the MaxHPChanged delegate

[bitter folio]

Inside the function , you manipulate the MaxHP variable, and call the MaxHPChanged delegate This being in the thirdperson character still?

[gentle urchin]

Is that who owns the MaxHP variable?

[bitter folio]

yes

[gentle urchin]

there's your answer ^^

encapsulating logic is a general principle, and I'd advice you to strive to follow it as best you can

[bitter folio]

then I can just bind the event to the HealthUp pickup right?

[bitter folio]

thank you

[gentle urchin]

your binding can just stay as it is

not really sure which BP is binding to it, but it should normally work from beginplay (unless you start already overlapping the MaxHP booster thing)

[bitter folio]

It would of been this I think (this is in the thirdperson character)

Anyways thank you for your help, you have taught me alot just now 😅

[gentle urchin]

which bp is this tho ?

[bitter folio]

?

[gentle urchin]

oh nvm i read below not over pic

xD

[bitter folio]

xD

[gentle urchin]

so

~~ encapsulating the pickup logic~~

The character shouldnt react to an overlap like this

since the character dont really know what iti's overlapping

so pushing MaxHPBarUp isn't something you wanna do

you only wanna broadcast it when MaxHP changes

and with your new encapsulation, that happens automatically by now

due to this;

which should call the AddMaxHP function

and not touch internal variables from externally*

[bitter folio]

You kinda just lost me ngl, I had not exactly set any of it to work yet, I was just trying to make them communicate first

So the MaxHp being changed from the pickup should be defined in the Player BP?

[gentle urchin]

The underlying logic for changing MaxHP should reside in PlayerBP

so inside a function

then the pickup thing should call this function

gimme a sec ill open a dumpster project

[bitter folio]

thank you

[gentle urchin]

In the PlayerBP;

[bitter folio]

Oh I see

[gentle urchin]

and then inside the pickup thing;

Now if you were to... only have like 3 different pickups for max HP, I would take it one step further

Lets call them Small, Medium and Large

I would possibly create 3 more methods (or add some enum or gameplaytag to identify which one )

doing this would once again achieve that any update to these settings would only need to be changed 1 place

[bitter folio]

and this in each Bp for Small medium and large?

[gentle urchin]

this example would still be inside the PlayerBP ,

then the pickup would simply call the correct one

[bitter folio]

Ohh

I think I get it now

[gentle urchin]

third option with tag would use something like a switch internally

[bitter folio]

Alright

Thank you so much for the help, this was eye opening xD

[gentle urchin]

100 ways to skin a cat, ofcourse

[bitter folio]

yeah lol

also a cool way of doing it

[mental trellis]

But only 1 of them spawns landscapes on tick.

[past hull]

dumb question , how do I create a variable proper to a function in blueprints ?

[dawn gazelle]

You mean a local variable? A variable that only exists within that function?

[past hull]

yes

[barren tangle]

hey, with a pawn, is there a way to find the number of the player controller that control that pawn?

[dawn gazelle]

With the function selected, you'll have an option for creating a local variable.

[barren tangle]

if i spawn pawn, for multiplayer (local) and i need to find the number of the controller that is used by the pawn.

[past hull]

I cant find it

[dawn gazelle]

Sorry it's when you have the function open.

[past hull]

oh nice, thank you

[gentle urchin]

Why you cry Datura ? You dont like the tag to health switcheroo? 😅

[lunar sleet]

Leave the poor cats alone you savage

[gentle urchin]

Woops. No cats where harmed during the experiment !

[dawn gazelle]

yea painful T_T wish there was a select node that could take a gameplay tag.

[gentle urchin]

Ah yeah that'd be something !

[reef totem]

Found the solution. I was using complex collision. I made a simple collision box and it works. For some reason collision wont work when moving objects using set location with complex collision 😠

Edit: NVM not sure what fixed it... I some how broke it again

[eager thicket]

does the delay node in blueprints continue to time out if the game itself is paused?

[steady night]

hey guys need help

im trying to launch character away from a location (this not launches away from player)

[rugged wigeon]

(get player character location - target location) -> Normalize

[steady night]

?

@rugged wigeon

cool seems to work

[bitter folio]

is there a way to decrease the size of the red health when my max hp goes up without the bar getting bigger?

[gentle urchin]

Its height?

[bitter folio]

no like say I have 100 hp then I gain 20 max hp, I'd like red being the current Health "lessen" and then there be room to get 20 more hp without bar size increasing

[patent mango]

why do you wanna decrease the size when hp goes up ? like shouldnt hp be directly propotional to the bar ?

[bitter folio]

im having a hard time saying what but I think thats it

[patent mango]

create a function , whenever your max hp increase set your bar's ratio to current / (max + hp gained)

[dawn gazelle]

The bar can always be thought of as a percentage, so a value between 0 and 1.
If you have 100 HP to start, and your max HP is 100, then the value is 1 as you're taking Current Health divided by Max health = 1.
If you increase your max HP to 120 but leave your current HP as 100, then the value would be 0.83.

So yea, as sherlock said, every time you modify either of your health values, you'd want to recalculate the percentage bar's displayed value by current divided by max.

[bitter folio]

I know theres def somthing wrong here, It seems like it updates the health to the max hp atm but the progress bar is not going above 100

[patent mango]

have you updated the max health ?

wait

[bitter folio]

yes I have a pick up that sets it to 120

Id asume its bc the health bar widget is set up wrong?

[patent mango]

why are you setting max health as max health / health ?

[bitter folio]

good question

[patent mango]

😭

[bitter folio]

😅

[patent mango]

if you have updated max health no need to set it

instead health / max health and send that pin to the input of set percent

that should probably work

[bitter folio]

\

like so?

[patent mango]

dont set

just send that pin to in percent

[patent mango]

if you are setting it will be reducing the current health and that is something you shouldnt want

ok

good

now try

remove

[bitter folio]

no dice

[patent mango]

the set pin

[bitter folio]

oh my b

nah still nothing

Im like 90% sure I have my widget set up weird

[patent mango]

are you sure you have increased max hp ?

by 20 or whatever amount you wanna increase

[bitter folio]

yes I have a debug key to read current hp then when I go heal it heals to 120

[patent mango]

hmm that should be working then

[bitter folio]

here is how my health widget is set up

[patent mango]

why is it multiplying ?

[bitter folio]

tutorials I watched said it would mess up without that

[patent mango]

ok got it

[bitter folio]

would I not need to do somthing simular as I did for health in the widget?

[mental trellis]

Because percent of often represented as 0->1 instead of 0->100.

...for some mad reason.

[patent mango]

i think this is wrong because you have used 0.01 to convert health into percentage but on increasing hp by 120 it will work still the same

so instead of using 0.01 go with the basic approc of dividing it by max health

for example if health is 90 percent will be 90*0.01 that is 0.9 but even if you increase your max hp that function works the same

[bitter folio]

like this?

[patent mango]

yes

[bitter folio]

how might I be able to use the health Variable? do I just create one in this called health?

[patent mango]

why not use one from event

[bitter folio]

true

hm doing the same thing

[patent mango]

can you show the increase max hp function once again?

[bitter folio]

like if I have full 100 hp before picking it up It does not look like anything happens but if im damaged and then I pick it up it sets my health in the bar to max but actual health is not changed

this is in the Third person character BP

[patent mango]

where do you increase you max hp if not in this function ?

[bitter folio]

from the Player Bp I think

[patent mango]

can you show ?

[bitter folio]

First is in player bp second is in the pick up

ah that set percent should not be there still

[patent mango]

why are you setting percent here ? and if you do why create a new function

also dont set percent as max health

thats wrong

[bitter folio]

Yeah I was playing with it before asking its removed now

[patent mango]

i would say in this function set percent to health / max health and remove the above function you wouldnt need that

[bitter folio]

like so?

[patent mango]

should work

[bitter folio]

Ok it worked but, when healing once it remaxed out the bar

also seems like after taking damage the max health displayed it reset to 100

😅

[faint pasture]

Why is an interface involved?

You're making this way more complicated than it has to be

[patent mango]

true

[bitter folio]

I dont know 😭

I just followed a few tutorials over the week on how to set up basic things then did bunch on my own

[faint pasture]

Ok first off, when does the healthbar update?

[bitter folio]

for the current hp?

Should be on damage

[patent mango]

show the damage code .. and healing as well

[bitter folio]

here is this, probs hard to read but at the bottem im doing the x.01 thing id imagine thats an issue

[faint pasture]

why does percent not depend on max health?

[patent mango]

likely

[faint pasture]

First off, forget telling the hp bar to update, just have it poll for now

get it working before worrying about perf problems you don't have

[past hull]

hey, I have an issue here because I want to keep track the Current Weapon OBJECT, so I created a new variable to clone the value but its only cloning the reference. So when calling Destroy node, it also destroys the Old Current Weapon reference wich make sense.
How can I get a clone of the Current Weapon object ? In oriented object programming I would just create a clone method inside the object and make something like this : OldCurrentWeapon = CurrentWeapon.clone();
But what about blueprints ? Thank you !

[bitter folio]

? the health system works its just the bar thats the issue

[faint pasture]

use your max hp in the percent math

[bitter folio]

like so?

[faint pasture]

Sure that should do it assuming 1.0 is considered to be 100%

might need to multiply the whole thing by 100, not sure what range Set Percent expects, if its a 0-1.0 range or 0-100

[gentle urchin]

You ditched my encapsulation comment already 😦

[bitter folio]

I did?

[faint pasture]

Once this is correct, you need to call the same code whenever you change health for any reason (changing the max for example)

make sure ALL changes in Health or MaxHealth make it to the Set Percent code

[gentle urchin]

Well, i guess not since its in the correct bp. But add a function for chabging hp aswell.

[bitter folio]

Ill get to it these are from prior of me learning

[gentle urchin]

Surely it'll be called from elsewhere aswell, so making sure the dispatcher always goes along with it is a good start

[bitter folio]

it seems that one change made everything work

[faint pasture]

In the future, dependenies like this are typically pretty brittle. A better design is to have the health system NOT CARE about a health bar at all. Either the bar queries for the values it needs, or the health system has a dispatcher it fires to let whatever cares know that its numbers have changed.

the bar depends on a health value, the health value does not depend on a bar

[bitter folio]

the health is independent of the health bar already tho

I just could not get it to display correct

[faint pasture]

no its not, go delete that health bar and see what happens when you take damage.
It'll try update percent on something that doesn't exist

[woven pond]

Would some one please help with what I am missing if I am trying to build an array of data assets prferebly by class of a specific PrimaryDataAsset.... im in unreal 5 and trying GetAssetRegistry > get asset(s) by class but it seems to be returning nothing (This could be me failing to build the path as its completely different to any info i found previously if trying to use by path instead of class....)

[bitter folio]

oh I see what you mean

My bad

thank you everyone for your patience

[faint pasture]

If you're jsut starting out honestly just polling is fine

[bitter folio]

I started 5 ish days ago

[faint pasture]

hp bar just has to figure out what actor or component it cares about and it can just read the values on tick

[bitter folio]

ah

[faint pasture]

I wouldn't use polling if I was making WoW but if there's only a few dozen healthbars around it literally doesn't matter.

[past hull]

help

[patent mango]

why do you wanna keep track of the object you destroyed ( sorry if thats a rubbish question im not so experienced )

[past hull]

Because I want to set it to the Primary or secondary weapon slot after the weapon switching

[faint pasture]

don't destroy

or if you do destroy, spawn it again later when you want it back

[patent mango]

so cant you just use class instead to keep track ?

[faint pasture]

I don't think there's an actor clone node but you can store its class then respawn it later

the blue pins are just pointers.

[past hull]

Ok so I used the "Detach From Actor" node and it seem to be working

[faint pasture]

Many people having my address doesn't stop my house from being destroyed when it gets bombed

[faint pasture]

That just detaches, where does it go, just float there?

[patent mango]

never understood better

so about it cant you just keep track of the class.....?

[faint pasture]

Yeah if you had to represent a stored item the class could work

assuming the class as default is how you want it spawned

or you can just hide it

It'd still exist, just be hidden

[past hull]

I mean, switching weapon is just attaching and dettaching from the "Hand" Socket no, and keeping track of the correct weapon with a "current weapon" reference right ?

[faint pasture]

That can work, where does the detached one go?

[past hull]

I dont know ahah

[faint pasture]

find out

does it just float in the air

[patent mango]

how about you send it to some random location no one can see

[past hull]

this is my current function

[faint pasture]

You can leave it attached but hide it, or attach to a back slot, or whatever

You should find out where they are going on detach tho

[faint pasture]

My guess is either they float where they last were or snap to 0,0,0 world coords

[gentle urchin]

Get owner pawn -> cast to firstpersonchar -> bind to healthUpdated etc

[bitter folio]

whats that for

[patent mango]

what happens to detach components usualy ... like they fell off right ...?

[faint pasture]

if you wanted the health bar to be notified of when health is updated without the owning thing knowing or caring

[past hull]

animation is broken but I believe I should fix this in the Anim BP

[faint pasture]

if they're simulating physics sure

look around

[bitter folio]

oh

[faint pasture]

print location on tick in weapon

[past hull]

I am looking but cant find an answer

[past hull]

i 'll try

[gentle urchin]

So char doesnt care about ui, but ui cares abput char 🙂 one way link , the right way

[bitter folio]

this is a function?

[past hull]

yes it goes to 0 0 0

[gentle urchin]

In widgets, yes, get owner pawn is a function

[past hull]

@faint pasture @patent mango thanks a lot btw

[gentle urchin]

Requires owning controller to be plugged in when you create it tho (Create Widget, that is)

[faint pasture]

I still wish a widget had a way to figure out it's inside a widget component and therefor find its actor

I haven't sorted out how to do that
