Guys I need help with PCG. When I scale pcg volume it comes with an error. Surface sampler says something like too many points created. So how can I fix that? How can I scale that volume up to the landscape. Also when using "unbound" option same goes.

[lunar sleet]

Try #pcg-framework

[snow drift]

Thx

I put an important struct in there. The struct is a database of objects and i imagined it would be stupid to put it in every cell, so i decided to just put it in the grid and make the cells access it when they need it.

hey people i have a doubt regarding a project i'm working on as i got struck in the way , i made a project based on a plugin where i drag and drop from the UI which created using data assets , i made a pillar blueprint and attached a component(bridge component) using socket method and in bridge blueprint i made it to attach to another component i.e, tracks to attach to it using same socket system . now all i can do is i drag a pillar it appears in scene and when i drag bridge part it attaches to the pillar and when i drag tracks it attaches to the bridge only but all this happens to the first pillar once i try to add another pillar from UI components attached to 1st pillar stays with the pillar, and when i try to drag bridge/tracks from UI it straight-up goes and attaches to the 1st pillar only all i need was everything happens with 1st pillar should happen to the 2/3/4/5....so on pillars. can anyone tell me how to work on this?

[fathom basin]

@pine mesa use get player controller and make it on possessed and not on begin play

I think it should work

[outer frost]

@short ivy AFAIK the UniqueID you get on interchange nodes is only in the context of the import.

Interchange = customizable import.
In short: Interchange Base Node is temporary representation of imported data, before call of factories to create assets. You can access and modify those nodes if your create a custom pipeline that you add to the pipeline stack used for import of your file. Not all file formats supported by UE will import through Interchange.

In Long:
Context: new framework to import (export will come later) data into UE. Currently supporting Textures, gltf/glb, MaterialX, Obj, FBX (experimental), some CAD file format (experimental)
Benefits of Interchange is that it is highly parameterizable: more import settings are exposed, you can create and store different presets for your model imports.
Interchange breaks imports in different steps:

• Translation of your file into an intermediary node base representation carrying the payload from the data
• Creation of factory nodes to generate assets and actors (in case of level import)
• Execution of factories to actually creates the assets

Blueprint usage with Interchange can mean two things:

• how you call Interchange functions to trigger imports: https://dev.epicgames.com/documentation/en-us/unreal-engine/importing-assets-using-interchange-in-unreal-engine#importanassetusingblueprint
• how you can now hook inside the import process and perform operation on the intermediary representation, on factories settings or on post import assets. This is here you will have use for the Interchange Base Nodes. Look at how to create a custom pipeline here https://dev.epicgames.com/documentation/en-us/unreal-engine/importing-assets-using-interchange-in-unreal-engine#createacustompipelineusingblueprints or here ( section on "Create custom blueprint pipeline", doc a bit old now in some parts) https://epicgames.ent.box.com/s/r6yhe2uzme1x6orisfwwqas0a3d6e6rk

Hey guys is there a way to flip the gravity upside down for my player character?

[fathom basin]

You need to create black board conditions for all the sequences I believe

For example for the first patrol It would trigger if robotstate is not equal to attacking

[grave relic]

I have load level instance in my Level BP but it does not spawn my instance of the level. Anyone knows why?

Hey guys, I’m new to Unreal Enginge and I’m trying to make a little carnival shooter game in unreal engine 4.27 where you shout cans and stuff over some water.

It’s pretty much done, but I’m missing the effect where if my cans or my bullet (the standard UE bullet) fall into the water, a splashing effect triggers.

Now sure how to get this done and I’d really appreciate some help.

[frosty heron]

@misty quail https://m.youtube.com/watch?v=yzvq8aonDYQ

Not a tutorial or gives u what u exactly need

But he goes over the idea how to make the ripple effect

[mystic edge]

This could be useful @misty quail https://youtu.be/dMGJv23ezrc?si=V2JAzfowaKiKYT2p

Not exactly what you want but it could help you start

[gritty wraith]

Why don't this work

Theres clearly an error with the binding, i did a few tests.

and no, the cast is not failing.

[gentle urchin]

Ohh yes

Listen once delegates

[fathom basin]

Set the gravity to negative

[misty quail]

Hmmm okay, thank you

[misty quail]

Alrighty, I’ll take a look. Thanks!

[silver blade]

Is there sort of an 'if actor of class' node I can use to check the attached actors of a pawn?

[tepid raft]

how can i make it so once player reaches 0 hp they die and game end

[gritty wraith]

ok nvm i can't stream my screen aparently...

[silver blade]

https://www.youtube.com/watch?v=ZpQmL_TzSPo

Or tie the hp to a variable, and once that variable reaches 0 > open level (set the level name to your level name)

[tepid raft]

tanks

https://tenor.com/view/leopard-tank-tank-attack-gif-15994800

[silver blade]

no problem, alternatively you can also use the Open level by object reference; that's probably easier

[silver blade]

I realised my problem from yesterday stems from the attached quests information not being relayed, but I need a way to find the quest in editor

it work

[trim matrix]

ofc

[tepid raft]

hallo

why say ofc

[rapid helm]

i don't mean it literally

i want to be able to jump and other stuff while i'm flipped

negating the gravity only makes me fly

[lofty rapids]

casting, or maybe == ?

[tepid raft]

how would i make an abillity that would summon a wall and has ui that will count down till u can use it again

[limber parcel]

do you expect us to write a full tutorial for you or what?

[tepid raft]

didnt mean it like that mean like where would i start with smth like that

[limber parcel]

i would start by summoning your wall

[tepid raft]

im bad at writing

sry

[lofty rapids]

you could use maybe a boolean for enabled, when its enabled run it and disable it, then on a timer set the boolean back so you can use it again

[tepid raft]

ok thank you

[fathom basin]

Make jump z velocity negative too and add to the rotation of your capsule component by 180 degrees to flip it

[rapid helm]

You can't negate jump z velocity

[fathom basin]

Oh

[rapid helm]

And i did rotate my capsule component by 180

[fathom basin]

Can you show the code if you don’t mind

[rapid helm]

it's just what you wanted me to do

Been stuck for a while

Oops forgot to connect the target on gwr

[mild wharf]

I am facing several issues while char is sitting. One of them is Head Rotation. Usually it will be be controlled control rot yaw. Even though turned of control rot head movement is also stops rot.

Worked head rot movement with control rig and anim BP by getting world rotation

How can I achieve this ?

[lofty rapids]

Why couldi not find these tutorials when i look them up 💔

[limber parcel]

its because google uses garbage algorithms that focus on showing you ads instead of the results you want

[crystal flax]

hey can anyone tell me how can i make phone like gta 5 in unreal engine i cant find any tutorial related to it hope you find

[thin panther]

The GTA phone is just a widget, that will switch it's current widget based on which button you press

Try not to look for tutorials for things like that

build the foundational knowledge

Someone that makes a tutorial for that, doesn't do it for a quality learning resource, but instead tries to ride the wave of name dropping the game.
At least in the current state of unreal community resources

[cobalt gulch]

I can help with that

dm me

[dark drum]

For a small fee of £29.99 an hour... 😄 lol

[cobalt gulch]

fr

i already have one made

not even joking lol

wait ill load it up rn

[mental sequoia]

Is there a way to spawn both a regular character and a vr pawn in a level, and switch between using them, using blueprints? For instance, the player character could be played on a monitor, while the vr pawn could be played in a vr headset, and running a function switches between using those two.

A video explaining a possible solution would be nice.

[cobalt gulch]

I wasnt joking

Last year i tried to make gta

btw whats the easiest way to do a random out of 5 different things

[lofty rapids]

maybe an array ?

what are the "things" ?

[cobalt gulch]

spawning an actor

[lofty rapids]

arrays have a built in random

[cobalt gulch]

I just need to spawn a random actor

pretty much

[lofty rapids]

you can have an array of classes

and spawn it based on the random one

[cobalt gulch]

okie dokie

[trim matrix]

Struct array element is not set
Anyone spot a fatal flaw in my logic, or know of any reason why the values in this array struct are not being set?
(Racing checkpoint system trying to support multiple local players so that they can track their own checkpoints cleared to test against them when starting a new lap / crossing finish line. Everything is as expected up until this point where I am trying to set a value but I am 2 arrays deep and they are structs...)

[fathom basin]

Make an array and place a random array node

[cobalt gulch]

How can I set the rotation to either 90 180 360

On a random basis

[frosty heron]

random int in range and select node

[frosty heron]

random int in range is not random float in range

also that's not what i mean

[fathom basin]

And make it from 1 to 3 and make a branch to see if it’s equal to 1, 2 or 3

[crystal flax]

i thi k that way only but isnt it to bee too many widget for one phone and later it create performance issue i am just worry that only

[thin panther]

Of course it wouldn't be.
Don't measure performance on a guess. Measure performance on something

[cobalt gulch]

Im not sure

[thin panther]

The only time it would become problematic if everything was on multiple canvas panels, but in that case you were shooting yourself in the foot from the getgo

[gentle urchin]

Random int 0-3 * 90

Oh, 270 was not an option

[crystal flax]

okay rest i all know how can i make that phone i was just looking for some other way i will try it thanks

[cobalt gulch]

all 90 multiplications are fine

aslong as its 90s

[gentle urchin]

Kk

So random int then * 90

0, 90, 180, 270 - 0 to 3

[cobalt gulch]

gotcha

[fathom basin]

👍

[cobalt gulch]

Is there any way to set a variable within the spawned actor?

As this is from a random spawn actor

[gentle urchin]

Yes

Either create a base class, which the array uses as class, and expose the variable onnspawn (preferred)

Or cast the class to your baseclass and set it that way (less clean)

[cobalt gulch]

How can I do the latter

[gentle urchin]

Do the former instead 😆

[cobalt gulch]

nah the former sounds a pain

ahaha

[frosty heron]

pain is part of the game

[lunar sleet]

But why do you look like penguinz0? 😀

[cobalt gulch]

alr ill look into this tomorrow

[cobalt gulch]

new hair cut

[lunar sleet]

Uncanny 😀

[gentle urchin]

Its litteraly the same work

[dark drum]

What type of variable?

[outer torrent]

Hi guys

I'm making a thirdperson game, and I wanted to make my character spawn a meteor in front of him. But I'm failing to do the calculation to get the front of the character. Does anyone have any tips or ways?

In the end, the idea is that the meteor always appears in the direction the character is looking, at a height X and distance X from the character.

[thorny elbow]

im not too familiar with blueprints and my vector math is kind of rusty, but i would assume to at least get it in front of the character, get the position of the character, then add that to the foward of the character times the distance

[lunar sleet]

Get actor forward vector

Times distance + location

[outer torrent]

Okay, I'll try, thanks for the help🤘

[limber parcel]

you can get your characters forward vector and multiply it by the distance you want

[thorny elbow]

^add it to the character's current world position as well

[cobalt gulch]

Float

[bitter star]

hi guys, I'm trying to have an actor appear when I trigger an OSC control and disappear when I press it again. Should I spawn the actor then destroy it or add the actor BP to the scene and toggle the visibility?

[valid mesa]

you can use level blueprint but if number of actor is too many it will be unoptimized. Can you explain the system a little more?

[gentle urchin]

Id rather put the spawn logic in its own actor

LevelBP is deprecated

[bitter star]

i have a static camera and i want to have an object (actor) appear when i press a button in resolume (message sent through OSC). When I press the button on object should appear then disappear when i send the same OSC command

[gentle urchin]

And generally shouldnt be used.. not many scenarios is it a good fit for

[bitter star]

I'm controlling all my OSC messages in a BP (not level BP)

[gentle urchin]

So you basically wanna spawn / destroy an actor when a specific message is sent

Youd need tonget a reference to the camera (i assume this was relevant) and can use that as a basis.for the spawn location (?)

[bold cypress]

Could anyone give me ideas why the hp bar would be set as the asset while the body isn't seen? I ended up putting the widget there and setting the visability off as a quick "Fix"

[low shard]

Hey guys, is "Draw Debug (Mesh)" supposed to ignore the alpha channel in it's color?

[bitter star]

Lets say I want to spawn a cube in front of the cam at 0,0,0. I got the logic working for this with spawn. Then I want to have 2 cubes in front of me instead of the 1 cube. I can spawn 2 cubes with new coordinates the same way but when I link the exe out of spawn into the destroy of the one cube I get error messages.

[gentle urchin]

Remember to store the references

[bitter star]

how do I do this?

[gentle urchin]

Promote to variables (or add to variable array)

Right click return value -> promote to variable

[warped juniper]

So, I'm making a function to detect when the player is falling down. I wanna use this to detect the apex of a player's jump for gameplay purpsoes...

Since for whatever reason, the default apex jump seems to do nothing.

Also using it on "start falling" just makes it trigger as soon as you jump, because falling counts both going up and down.

[bitter star]

I get the following message: "Blueprint Runtime Error: "Attempted to access GasCylinder_C_0 via property Gas1unit, but GasCylinder_C_0 is not valid (pending kill or garbage)

[fathom basin]

Make it a less than node instead of a less equal node

[bitter star]

Gas1unit is my variable for my "1 cube", not sure what GasCylinder_C_0 is

[fathom basin]

@warped juniper

[gentle urchin]

Show code

[warped juniper]

Actually since I want the apex it IS less than or equal since the apex of a jump is the moment it has 0 movement along the vertical axis.

[bitter star]

sorry for the pic, I dont know where the screenshots are stored on PC (looked in the pictures folder but i have nothing...) :/

[warped juniper]

@fathom basin Other than that, how else can I make use of this?

Or is there a default function that does what I want.

[fathom basin]

But when you’re on the ground you also have zero z velocity

So make a branch with is falling before you check for the z velocity

@warped juniper

[warped juniper]

Hmmm true

In that case

I should make a separate bool that returns true if the velocity becomes 0 from a positive value.

@fathom basin This is the new version.

[fathom basin]

Does it work?

[gentle urchin]

You shouldnt cross wires like that

Dont cross pins from different exec paths

Grab new ones, "Get whatever"

Then chevk if they exist by using IsValid

Then destroynif they're valid

[bitter star]

could you show me an example?

im not super familiar with the isvalid variables

[warped juniper]

I don't know how to start using this properly...

All I can do is call the function, thing is I want the event to just fire away on those conditions...

But I cannot just have it on Event Tick.

Though it does work in that case.

[gentle urchin]

Isvalid is a node used to chevk if a variable is not nothing, but actually points to live instance of the thing it references

[faint pasture]

use win shift S

then just paste here

or print screen and paste here

[faint pasture]

isn't apex already an event on CMC?

[faint pasture]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Character/OnReachedJumpApex/

If you must do it yourself you'll have to just check on tick

which is exactly what the CMC is doing

[warped juniper]

Hmm...

It's not too clear in engine.

Thanks for showing me that though.

[eager thicket]

I want to get each int in an array and compare it agaisnt a single number. How would I do this effeciently?

[warped juniper]

Alright, here's the current state of my jump.

[faint pasture]

oh you're messing with gravity during a jump

[warped juniper]

Yeah

[faint pasture]

see if the notified apex still works

it might

[warped juniper]

I'm making a platformer kinda thing...

I'm really unsure how to better improve it

It's just so floaty...

This is all I can add there.@faint pasture

Doesn't seem to do anything.

[faint pasture]

Have you hooked it up or is this as far as you got

[warped juniper]

I have

I just used a simple print after binding and returns nothing.

[rain wraith]

Are blueprint interfaces not able receive multiple targets inputs? I have an interface which works fine when the target input is just one input but as soon as I add a second (I want to have 4 target inputs total) the compile throws an error. The target input node itself is able to receive multiple inputs though

[warped juniper]

Ah! Wait...

[faint pasture]

That's probably just some syntax sugar on making the interface call on an array of targets

foreach your targets and do the call on them

[warped juniper]

Alright!

I did it

The notify jump apex needs to be toggled on / off whenever going to and from falling

Weird that it doesn't do that by default...

[rain wraith]

So instead of having one call to the BP interface that intakes all four targets to one target input, just duplicate the BP interface call four times in a row and input each target alone into each target input?

[warped juniper]

@faint pasture Sorry for the ping, but for doing some debugging I need to calculate time elapsed between 2 functions getting called... Do you have some feedback on achieving that?

[faint pasture]

you can do a loop

[faint pasture]

You gotta get the current time in each function then do math

FirstFunction -> ??? -> FirstTime= GetGameTimeSeconds
SecondFunction -> ??? -> PrintString(GetGameTimeSeconds - FirstTime)

[warped juniper]

Ah, fair. Thanks for that.

I'm trying to clean up my jump programming process..

[rain wraith]

Hm not sure what you mean by that. Sorry this is my first time ever using BP

[faint pasture]

get all of your targets in an array

for each loop

[golden kite]

ARe you looking to find the index at which the first occurrence of that Int occurs? There's a FIND node for that

Otherwise if you're looking to do something every time you find that specific int in your array, you can use a for each loop on the array.

But I'm suspecting this may actually be a symptom of a higher-level architecgtural decision. What exactly are you trying to find an int match in your array to do?

[eager thicket]

This is what I'm trying to do.

I have a spline road BP with a default mesh set to each element.

There's also an array of integers. Any numbers in the array will be compared against the spline BP elements, and if any match, it overrides the road for a new mesh.

Currently works for one number only.

[golden kite]

What's the role of the array of integers. I mean, why did you choose to do it that way? @eager thicket

[gentle urchin]

This doesnt really work does it

Wait, i prob misunderstood.

[golden kite]

What do those integers represent? Are they associated with that "tile" or element of the road?

[gentle urchin]

If they're executed at different times and not in the same chain, then yeah it would

[eager thicket]

A designer can select what numbers to change in the BP spline via that array of integers

in the details box.

So like "I want segments 8, 12, 16 to have this specific road mesh"

etc

[golden kite]

How do they associate the mesh they want with the integer. And why an integer and not a string like "road-with-tree", "road-right-turn" etc

(if you're trying to be designer friendly I mean)

[gentle urchin]

That sounds a little troublesome

How about a custom editor widget instead, which can act on directly selected meshes /instances ?

Add some pcg to this and you have a neat little tool

"Randomize this section"

[eager thicket]

I haven't gone boilerplate enough to figure that out. Currently I'm just building functionality one little bit at a time, starting with being able to change any section of road you want with a single mesh override.

[golden kite]

"pcg"?

[gentle urchin]

Procedural

Content

[golden kite]

So explain the defualt road structure to me. It's a pline with a fixed amount of nodes or?

[eager thicket]

It's a BP road spline that can be set on construction, and it can have as many or as little spline elements as you want

depending on where you drag it

[golden kite]

and the array of integers - does it have to correspond 1-to-1 with the number of spline elements?

ie: if you drag the spline and it creates a different amount of elements, now you have to go in and re-edit your array of integers?

[eager thicket]

I'll check.

[golden kite]

Not that I want to complicate your life, but this really sounds like a construction script kind of thing, or maybe an editor-widget, where you can select the spline element and change its mesh interactively

[eager thicket]

Thankfully, no. dragging out the spline doesn't require the other array any editing. nor does it change the overridden mesh positions

[golden kite]

Okay, my spidey-sense is still tweaking that there's probably a better way to architect what you're trying to accomplish that makes it even more artist-friendly, however...

A siple implementation would be to have two arrays:

Scratch that.

A simple implementation is to create an array of static meshes.

[eager thicket]

🤔

[golden kite]

So that way, the artist doesn't have to remember what the ID of a particular mesh is. Let me post a quick example to see if what I'm saying makes any sense

[eager thicket]

Im gonna quickly run downstairs and grab some cereal, but i'll be back in 5 minutes

but I am interested

[sage lagoon]

Since I can't put macros into a function, what would be the next best thing? I could use custom events, but time delays within custom events are often ignored.

Like this, for example:

[golden kite]

I'm thinking something like this might be artist-friendly:

(If I could spell "element")

[golden kite]

Are they though?

[golden kite]

Anyway, I wouldn't use delay for that, I'd use a Timer

[sage lagoon]

How do I use a timer within a function? I haven't tried those before.

[outer torrent]

Guys
I'm trying to make my meteor follow in front of my character (thirdperson) when it's spawned, but I'm not able to "rotate my forward", it's "stuck on a single axis"

I will send an image of what it looks like in the blueprint and a video

[lofty rapids]

probably because you multiply by 0.0

but i don't download videos, maybe use something like streamable

or think discord will embed it if it's a certain type, but i don't know what type of video it needs to be

[golden kite]

I think it depends on whether you need to pass a parameter to the timer.

[fervent breach]

sorry for the late reply, if I create enemies when they are needed, how would I go about special instances where an enemy would have different variables than their default? Would I just place all the enemies in their room, assign their variables, then have my spawners copy the enemies and destroy the originals? Or would it be something like, place all the enemies in the room, set the variables, and then make a blueprint of the entire room? Which I guess would be fine, though it sounds like a pain to go back and fix anything, and I would imagine it could easily get in the way of testing 🤔

Sorry if I worded any of this poorly. I'm mainly having trouble getting the custom variables to the spawned enemies. Not helped by the fact many of my enemy classes have their own very unique variables, so just making a general script only gets me so far (I have an enemy parent class, but that mainly just holds any universal information, such as health, armor, damage, detection radius, etc...) Like, how do I store these custom variables as well as what specific enemy I want to spawn and where they are meant to be placed.

My first guess would be placing the enemy in the level, changing their variables and then... I don't know... as far as I am aware I can't make a temporary instance of an object that can be created and destroyed during runtime (ex: having my spawner make a new blueprint of a custom enemy, destroy the enemy, and now create the instanced enemy with all the changes to its variables intact)

My next guess would be a struct of all variables that can be changed, and sending any editable variables to the EnemyParent - but 1) that just sounds like a hassle and I feel I am missing a better solution, and 2) all of my enemies will now have access to a ton of otherwise needless variables - it's not the end of the world or anything, it just makes me think I am overlooking or unaware of some function that would work better

[sage lagoon]

To be more specific, I want to put in a delay between when text appears in a message box and when a clickable "next arrow" appears; and a five-second delay for pictures to pop onto the screen once those are done. I have an On Key Down function so that the player can use a keyboard if they'd rather hit a key to bypass dialogue text.

Unfortunately that doesnt work because the four targets I want to input are different pawns so they cannot be stored in the same array

[lofty rapids]

if i want to use a timer, i just use an event and call it

[lofty rapids]

you can store different pawns in a single array, not sure what you mean here

[golden kite]

The variables and all variations are stored in the enemy's blueprint class. So you might have a BP_Generic_Enemy and then a BP_Enemy_With_Cake. and they might all inherit from a parent blueprint eg BP_BaseEnemy. that parent blueprint sets all the defaults, but then your spawner script can select which specific variant of enemy to spawn, and they each have their own overrides where appropirate

[sage lagoon]

So would I use Set Timer by Event?

[golden kite]

They need to all inherit from the same bases class

[outer torrent]

That was exactly the solution, thanks for the help!

[lofty rapids]

ya, and i put it inside an event, then call it from the function, because i don't think you can do that in a regular function it needs to be an event

[golden kite]

So your array is made up of BP_BaseEnemy classes and then you can put whatever specific variant you want in there

[sage lagoon]

Something like this, then?

[golden kite]

right? So in your example, maybe HumanPawnObject is the base class and AviatorPawnObject inherits from that

[golden kite]

And then you can wired up to the event that gets called when the timer expires via that red dot

[lofty rapids]

but you need to go out of the event in the timer, and set the action in there

its not going to be a delay

you need a delay ?

[jaunty solstice]

What happened to OnMouseUp? Simply tryinmg to detect the end of a Mouse Drag operation in a Construction Script.

[golden kite]

Doesn't mouseDrag fire an event when you end the drag operation?

[sage lagoon]

Like this?

[lofty rapids]

no what are you doing with the delay ?

[golden kite]

Yeah you don't need the dela- the timer is replacing that

[lofty rapids]

the timer will fire after a certain amount of time, and the custom event is where you run the code you want to run after the delay

[sage lagoon]

Oh. What should I attach, then?

[eager thicket]

hmmm. is this performant?

[golden kite]

No reason it wouldn't be. It's actually less work because you're skipping an intermediate lookup step

[sage lagoon]

I could put in a custom event that causes the "next button" to appear, but what if I wanted a timer that extends so that more images will pop up? Should I just set the time to twice as long?

[eager thicket]

How does it work exactly? Like, to add a new part of the road, I don't drag out the road mesh, but I click the "+" on the details?

[golden kite]

Furthermore, I'd put it in a construction script and actually create those mesh elements rather than do it at runtime, unless you absolutely have to.

[rain wraith]

Question then. The reason I was trying to add all the pawns of four different pawn classes into an array is so that they can be used as a target input for a blueprint interface that transfers a var from the level blueprint to the pawn classes. Is it worth re-setting up the pawn classes in the way you're saying, as opposed to just doing four calls of the the blueprint interface that transfers the var - one call for each of the four classes. Like this (only 2 shown here)

[lofty rapids]

add the stuff you want to do after delay in the custom event, think about it you are running the function, you call the event, it sets a timer, and after the timer hits the custom event runs, which is where you could put the code you want to run

[sage lagoon]

Okay, so I think I know what I'll try. One second.

[jaunty solstice]

Thanks. What am I missing? Can you not set Mouse events in Actor Blueprints? Can't find the Mouse Drag.

[golden kite]

You're probably ovecomplicating that. The level BP should be able to get references to all its Actors anyway...

[rain wraith]

The level BP cant directly send var data to BP classes without cast or BP interface

[golden kite]

I know the input system changed in 4.x so if you're used to legacy input handling there might be some changes.

[sage lagoon]

Something like this?

[lofty rapids]

i hear a lot of "don't use level bp" on here

[golden kite]

I'm not sure about that. The Actors can all get a reference to their level, so they should be able to access any public vars on the level BP

[golden kite]

really eh?

[lofty rapids]

right then in the function, call the event

[lofty rapids]

yep

[sage lagoon]

Okay. I think I have an idea on how it works. Thanks, and to @golden kite too!

[golden kite]

Good luck!

[sage lagoon]

Thanks! I still have a bit of a ways to go, though.

[jaunty solstice]

Ah yes, the new 'Enhanced' input system 😂

[gentle urchin]

Not in BP they cant

Unless thats brand new

[gentle urchin]

Why would the level BP have this var, and not say, the GameMode ?

[lofty rapids]

i been storing everything in game instance or the actual character

i'm just learning about playerstate, gamestate

[rain wraith]

Great question. I have no idea. This is my first time even touch BPs

But I mean performance wise is there any reason I couldn't do what's in that image? The BP seems to execute fine

[gentle urchin]

I generally recommend people to stay away from LevelBP. While it may look tempting, and have cool direct actor access (from those spawned in the level) it's not often a good approach or place for logic to reside. Another thing to note is LevelBP's deprecation status

Performance is not part of the equation

Level bp wont be slower than other bps

[lunar sleet]

It just can’t talk to any other bps

[rain wraith]

No not the level BP itself, but just the fact that I'm calling the Blueprint Interface four different times, one to transfer the same var data to each of the four different targetted pawn classes

[rain wraith]

By GameMode, do you mean storing it in a BP GameInstance?

[gentle urchin]

Surely it can, but nothing else can talk to it ?

[lunar sleet]

Sorry other way around lol

[gentle urchin]

GameMode, GameInstance, GameState,

Depemds on whah this is exactly, but they can all be valid candidates

GameInstance is persistent

[lofty rapids]

i like the game instance because of that

[gentle urchin]

So if this was something like a setting from the main menu, that you need your pawns to read, then GameInstance would be a valid choise

[lofty rapids]

it's persistent

across levels

i use it for globals

[gentle urchin]

What you could do in such a case is to simply let your pawn read the data from the game instance. Elther on Beginplay or some other suitable event

It simply then goes :
Beginplay -> GetGameInstance -> Cast to MyGameInstance -> get var

[rain wraith]

Ah mkay. I mean my current BP works fine using multiple calls to the BP Interface for each pawn class its transferring data to. So as long as it's not a huge performance concern I'll just leave it as is

[gentle urchin]

Its up to you if you wanna accrue tech debt, and if you're willing to pay the price ;p

Extension, changing levels etc requires the same implementation over and over , as an example

If you were to add a 5th class, then you'd need to add yet another node in all your levels.

(Ofcourse you can get around this by grabbing the parent class instead)

[lofty rapids]

if your staying on one level np, but having to create everything for each level sounds like a pain

[gentle urchin]

GetAllActoesOfClass(Character) -> send interface event message

[rain wraith]

Yeah valid points. Something to keep in mind for future endeavours. This is just for a simulation for one of my univeristy classes so its just a one and done thing in its entireity

[rain wraith]

Yup thats how I currently have it. Just four of them for each targetted class

[gentle urchin]

You dont need to target the specific classes if they all get the same value

Just target Character (or whatever common parent they got) and send the message in one single loop

Then you could add 100 new classes to your project, and still not have to update that piece of code

[rain wraith]

They dont use the same parent class though so that doesnt work

[lofty rapids]

so you are having to get actor of class for each ?

[rain wraith]

Yup

[lofty rapids]

using a parent class makes that a lot easier

you can get all the actors of the parent class

[rain wraith]

True its just a matter of redoing the pawns that way

[lofty rapids]

are you just doing that on begin play ?

[rain wraith]

"that" being calling the BP Interface to transfer the var?

[lofty rapids]

the get actors of class

on begin play ?

[rain wraith]

It will done once every minute

[lofty rapids]

how are you looping them ?

get actors of class, then plugged into foreach ?

[rain wraith]

Set Timer by Event (looping) -> Custom Event -> Get all Actors of Class -> Call BP Interface

[lofty rapids]

makes sense

you have the array plugged into the function ?

i always forget you can do that for sure i'm not used to it

[rain wraith]

Yes the BP Interface target input accepts arrays

[warped juniper]

Hey, I have a quick question regarding controllers.
Do you reccomend rotating the controller, or the actor itself, when making a player character that turns to nearby targets for aim assist?

A projectile spawns from right in the front of the player to hit towards the current target.

[jaunty solstice]

Noob question. Is it possible to target a Pawn from within an Actor Blueprint?
I'm trying to add the new 'Enhanced' input system to detect Mouse up to an existing Actor Blueprint.

Or should I redefine my Actor BP as deriving from the Pawn class instead?

[outer terrace]

anyone able to explain to me or help figure out why safe divide is returning as not in scope?

both A and B are giving proper values

[lofty rapids]

what is self actor ?

what kind of class ?

[trim matrix]

GetPlayerController not GetController

[outer terrace]

^

GetPlayerController should fix that issue

for the life of me.. idk why this keeps getting out of scope everywhere i call it

like.. my 2 variables are very obviously set at 1... but both safe divide and == bool both return out of scope

and than it just passes as true in function ShouldInterpGhostBar and never gets set to false.. so its constantly trying to interp

[lofty rapids]

whats the magnifier all about ?

[warped juniper]

Hm, for some reason my function isn't turning the player towards the actor...

[outer terrace]

@warped juniper your Get Overlapping Actors doesnt have a class defined.. so technically it wont ever fill your array of checked actors

so you're not setting your firing target

[warped juniper]

Alright...

So, how can I get overlapping actors by tag?

[outer terrace]

by tag is is something completely different.. that would be a gameplay tag.. for instance if you want to make a game that has No friendly fire... and singleplayer in the most basic terms.. you would give your enemies a gameplay tag Enemy.. or w/e you want to name it

[warped juniper]

Okay I'll word it different.

[outer terrace]

than in get overlapping actors by tag you would search to see if they had that tag

[warped juniper]

I want to search for any actors, get the nearest one with X tag.

And make that the target.

[lofty rapids]

you want to search all actors ?

[outer terrace]

define an actor.. you could easily put someting like AActor class in that box.. but i really woould highly suggest not doing that

[warped juniper]

Only the ones within a range.

[outer terrace]

because it will search every single actor.. not just your players

[warped juniper]

Eh, guess I really picked a bad kind of game to make...

[outer terrace]

what are you trying to target?

[lofty rapids]

you could go with all within a collision sphere

[outer terrace]

objects and players, or just players? or objects?

[warped juniper]

Enemy actors, or stationary targets based in context.

[outer terrace]

do they share a parent class?

[warped juniper]

I sort them with a tag so I can differentiate enemies from other objects you can break.

[outer terrace]

if so. the parent class is what you would search against

[warped juniper]

I don't have a parent class for all of them...

[outer terrace]

if they all share a tag

[lofty rapids]

probably a good idea

add a tag and get all actors with tag

[warped juniper]

But they don't have a parent class

[outer terrace]

^

[warped juniper]

I haven't made any yet.

[outer terrace]

if they have a tag. you can just search by tag

you just are using the wrong getter

[lofty rapids]

but it's still a lot to loop through, how often will you be doing that ?

[warped juniper]

Hmm...

In that case

[warped juniper]

I should use get all actors with tag

Return the distance of the closest one

And if within X range, get that target.

[outer terrace]

i personally am a huge fan of creating an interface and giving all my interactable objects / characters that interface

[warped juniper]

Although I also want to add some control based on player orientation...

How complex could it be to instead use a cone of sorts to detect the actor?

I can't find something like that.

[outer terrace]

that would be sweeping detection methods

like creating sphere traces

[warped juniper]

Yeah I'd like a sphere trace that gains radius as it approaches the end.

[outer terrace]

so something like that.. you'd do a sphere trace.. it it has a hit it will detect if the actor has the tag.. if it has the tag it will add to your array of actors

you can stack the traces and do multiples using the same concept

[warped juniper]

Hmm, I still need the cone aspect though...

[outer terrace]

the cone aspect would be doing a multiple traces

[warped juniper]

The idea is that the player would prioritize targets by proximity, both to the player actor, and to the forward vector.

[outer terrace]

you'd have to do some vector math.. but thats the concept

and if your math is slightly off.. a good failsafe is to do a check to see if the actor is already added in the ArrayOfActors, and if so, ignore (dont add a 2nd time).. just incase your traces overlap

[warped juniper]

Hm well...

One moment

Okay, so Epic gave away some marketplace stuff

There's this asset called Line of Sight Dynamic mesh

[outer terrace]

yea. that method works as well

they have an invisible mesh in the shape of a cone and use OnOverlap ... than just do a linetrace to the object that overlaps to see if it gets a hit on the visibility channel

[warped juniper]

Hmmm...

Though with that method, I'm not sure how to return the proximity aspect.

The idea is that enemies closer to the player vector should have higher priority.

Maybe I should just do it on a proximity based system, I don't think it would be that bad to have nearly fully automated aim...

[outer terrace]

2 different things.. you want your functions in programming to do very distinct things. your detection function does 1 thing.. it detects.. have another function that fires off after that takes the actor location of only the actors in your ArrayOfActors and calculates its distance and targets the closest one

[warped juniper]

Yeah that's a good point there.

Regardless I still feel unsure regarding my project, once I'm actually experimenting with stuff here.

[rapid hollow]

Hello, I'm developing a project with blueprints and I'm getting an error when I try to cook that I cant figure out how to fix, would this be the right place to post that to see if anyone can help?

[faint pasture]

dot product my man

[warped juniper]

Ahhhhhh yes dot product, I remember it now

[faint pasture]

Sphere trace -> some metric based on distance and dot product -> now you have the closest most aimed at thing

[warped juniper]

I used that for making a DMC input system.

It actually works shockingly well.

Though, say... You think making a Mario 64 meets Metroid style of game might be shooting a bit too high, coding wise?

[faint pasture]

if it's single player nah

you can do all that in BP as long as you're not doing anything too fancy

The hardest thing about cloning Mario 64 would be the movement modes

If I were doing a single player platformer I'd probably just use physics

[warped juniper]

Well it's not cloning specifically movement of Mario 64

But the idea, 3D platformer across a series of levels you explore and collect stuff in.

[faint pasture]

If you're using Character, the further from walking around you get, the harder it is

[warped juniper]

Well the wildest idea I had was a movement move where gravity doesn't affect you at all for a moment...

As far as movement goes.

[faint pasture]

that's pretty easy

[warped juniper]

Yeah just get current Z post, lock the player to that until X happens.

[faint pasture]

for single player that can be BP only

locking and gravity not affecting are different things tho

does gravity turn off or does Z stop changing?

[warped juniper]

Hmm..

So you know how the flash can run over water?

[faint pasture]

sure

[warped juniper]

Pretty much that.

[faint pasture]

What happens if it's over a hill or staircase

do you float forward and NOT go up the hill or do you follow the hill?

[warped juniper]

Ideally, slide up if it's a slope.

If it's a wall, just don't move at all.

[faint pasture]

see it gets tricker and trickier

a simpler way to do that mode might be that you can now walk on things you couldn't before

like water

and of course you can do anything with the animation, you can move it up to be floating

but fundamentally, the capsule is still just walking

[warped juniper]

Yeah, but I imagined mostly it'd be used in crossing gaps and the like

[faint pasture]

Turning off gravity would work for that. What happens when you walk down a hill?

[warped juniper]

That's the neat part, nothing.

You just walk as if the ground remained at the same height.

[faint pasture]

So the rule is more like "Collision only moves you UP"

or, gravity is off and you're flying with collision

[warped juniper]

From the two, the former is the more accurate one.

Ah wait, I have a perfect example.

Have you played Super Mario Odyssey?

[faint pasture]

i know about it

[warped juniper]

Alright, there's a mode where Mario turns into a bullet bill.

While in this mode Mario has a fixed position along the Z axis.
Ramps slide him up, but cliffs and gaps are ignored.

That, minus the whole "explode on touching a wall" is what I'm thinking about.

[faint pasture]

So the thing to figure out is if you can do that sort of stuff with Character in blueprint

you probably can

if not, make your own movement system or use physics

[jaunty solstice]

Thanks!! Explains why my cast is not working!

[warped juniper]

Actually I sort of figured out a way to do it...

Not sure if it's ideal though.

I'm still considering if perhaps going for other ideas would be better for a 1 month proof of concept. This one I chose at first because it felt exciting, but is it unique, fresh, original...?

[faint pasture]

I mean you have to have something beyond moving and collecting to make an original platformer

[trim matrix]

because the input type is wrong, if you want to get the player controller WHICH YOU ARE DOING, you have to use 'Get Player Controller', the getController node is another type and will not work with the cast you are using

[warped juniper]

Right, of course... The base idea wa to mix the Metroid elements with a 3D platformer.

[faint pasture]

Because it's probably getting clobbered by whatever is normally setting your character rotation

[warped juniper]

The metroid franchise was always leaning more towards platforming than castlevania, so they have a native synergy.

[warped juniper]

Haha, yeah someone already helped me with that!

[jaunty solstice]

Yep thanks. Progress. Still something wrong though. Even when I wire ALL my EnhancedInputAction outputs (Triggered, Started, Ongoing, Canceled, Completed) to Print Strings I see nothing!

[trim matrix]

because something is wrong with your code / input ...

I dont know what tho

it can be a lot of things

[lofty rapids]

this is on your player ?

[jaunty solstice]

Just a Pawn Class.

I think the issue must be either with the way I've defined the actual Input Action and or Input Mapping Context.

I need to get examples of each I KNOW are working and then reverse engineer why mine isn't. Maybe the Marketplace has a sample?

[lofty rapids]

look at one of the templates

but idk if that will work if the pawn isn't possessed

i would first try with a hard coded input

like a key press

see if you can even trigger it

[junior prairie]

If you want only certain child blueprints to have variables and be able to set those variables when you spawn them in, you should set the variables to “Instance Editable” and “Expose on Spawn”. You can find that in the class settings or class defaults, I forget which. Then when you use the spawn ai or spawn actor blueprint node and select that child blueprint, you’ll see the variables as input pins and you can plug in whatever you want

Or you can go the struct route and that would be fine too

[celest trench]

Is it possible to make the character head always face the camera look vector exactly? I am using the lyra character in a true fps view and the head does not fully tilt with the camera or will look around during idle animations even though the camera stays straight

[hidden cedar]

Is there anyway I can attach my PLAYER to the CINE camera?

I need to make a small trailer, and my enemies are sprites so they must be looking AT the player so that we dont see them from the sides. I've made a sequence with my camera and my enemies dont look at my camera because they only look at the player

[gentle urchin]

Are they not all "Pawns" ? Children of Pawn?

If they're all direct children of Actors then id suggest a simple reparent. Doesnt nees to chabge anything, just reparent them so you have a common editable base, where you can add overlapping logic

(Id suggest that if they're all pawns aswell, really. Or Characters.)

[jaunty solstice]

Enhanced Input confusion.
Need to simply define input for the end of a Mouse Drag operation, so even Mouse Up might work.
Third person Template has some working Input Actions and a Input Mapping Context.
But how to define either Mouse Up or Mouse Drag detection?
Nothing in the Input Mapping Context I can see.

[warped juniper]

Well time to test something else...

What kind of variable can I use to store up to 3 values, and then run a specific function based on the values inputted?

[lofty rapids]

array ?

or struct maybe

[warped juniper]

Yeah I guess an array "works" but does an array also care about the order?

In the way I specifically want to use it.

[lofty rapids]

wdym "care about the order" ?

[warped juniper]

Yeah I need a specific example here

Sorry about that.

[lofty rapids]

you can store three values

then use the index to get the value

so index 0 is x, index 1 is y, and index 2 is z

something like that

[warped juniper]

The player use 2 inputs to insert a code to cast a spell.

So the values possible are 1, 2 and 0 (If no value was inputted in that array)

If the array has 3 slots, then 100 would run A, 110 runs B, 111 runs C, etc.

This is checked when pressing an input.

[lofty rapids]

i'm not understanding, what is 1, 2, 0 <-- these will be in an array like when you press each one it will be one or the other ? also what is 100 ?

[warped juniper]

The values of the array

[lofty rapids]

110, 111 ?

[warped juniper]

1, 0, 0

[lofty rapids]

what do those numbers represent ?

idk wym by 100 and 110 or 1,0,0 but an array can store multiple integers or floats

but you have to pick the type and all the array is that type

[warped juniper]

It would be ints.

Okay I know now

This is a morse code style system.

The code should "read" what the player inputs using morse code and perform an according action.

@lofty rapids Sorry if I failed to properly explain this..

[lofty rapids]

i see so your going to do some morse code stuff

1 short, 2 long or something ?

[warped juniper]

Yeah pretty much

With 0 for n/a, in case the player sends info under the array limit.

Probably would be nice to have a way to slot the arrays differently...

So that the 3 values of the array are the 3 most recent values.

That way it updates dynamically.

[lean compass]

are child actors bad for performance if they dont tick? i wanna use it for spawning in character cosmetics and attaching it to the player character mesh

[dark drum]

It'll probably be fine but why would you need them to be actors? If they don't do anything, you can just add a static mesh component or skeletal mesh component as needed.

[lean compass]

i was thinking if i added particle systems and maybe sounds too it it would be way cooler

and i want some of them to be animated too

just more freedom

[outer terrace]

anyone able to help me and figure out why this divide is showing out of scope instead of the result which should be 1? im so confused...

[dry sleet]

If you're gonna spawn them in at runtime I'd avoid the Child Actor Component and just spawn and attach the actors manually.

CAC is weird and janky.

Then if they don't tick you still get overhead from attach transform updates, but that's of course the "cost of doing business"!

[lean compass]

yeah i was doing that but then i was having problems with setting the actor hidden only for the client i was using set actor hidden in game

maybe the code was wrong but it was set to run on owning client only and it was setting the actors hidden in game

the actors are replicated so i dont know if that had something to do with it

ill try it again

[warped juniper]

@lofty rapids The main challenge now is the branch / gate based on the values of the array

[vestal acorn]

Is there a a better/more organized way to do this i.e. take a flot and disregard a certain range of the float ( between -5 and +5 ), then clamp to normalize depending on -/+

This feels a bit clunky

[lean compass]

fixed it with a rep notify

[chrome pumice]

https://www.youtube.com/watch?v=asgpEgJ8NTQ

ive just watched this video about substractive materials and i wonder if i can do this inside of a actor, does anyone know?

Right now im dooing it like this

[dark drum]

Generally pure nodes won't show the value as it doesn't know until it's been called/evaluated. That's why it shows out of scope.

The other ones show the values because they're an actual variable.

[outer terrace]

so i'd have to promote a local variable, set that and reference that than?.. just to get the bool in scope?.. weird. ok

thanks

was trying not to create more variables for one-off calls but i guess i have to in this case

[dark drum]

But then it would only show the value when it was last stored.

[outer terrace]

which is fine. whats happening is i'm receiving a broadcast when an attribute changes in my attribute set.. when that happens i'm setting a local variable "Target" and than instantly firing a event that calls this function to change bool bInterp to true.. than does a while loop to interp the percent of my progress bar until it reaches the same value as Target.. than setting bInterp back to false

[jaunty solstice]

ThirdPerson template has a excellent example of Enhanced Input system.
I took this and simplified it to just detect Mouse Up and Down.
Created a new Pawn Blueprint and pasted the attached logic.
Dropped in a blank level and presto, works.

Now I migrate this (Input Action, InputMapping Context, Pawn Blueprint)
to a blank project and it stops working. Of course Enhanced Input plugin is enabled.

Why doesn't it work? What else is necessary for input actions to work?

[outer terrace]

it works when i set a local variable..

just weird that i had to do that instead of just using my GetPercent blueprintPure function

[frosty heron]

@outer terrace delay on tick is pretty useless

U r just delaying the process initially

[outer terrace]

correct

its to run a delayed bar behind my HP bar

thats it functioning properly now.

just a cosmetic thing

[frosty heron]

And that's the wrong way to do it

[warped juniper]

Okay game 2 of the prototype and testing phase.

The goddamn projectile won't collide with anything.

[outer terrace]

how would you do it than?

[frosty heron]

Interp on tick is right for the ghost hp bar.

If you want to add some delay before the hp start dropping down, use timer

Not on tick ofc

[outer terrace]

the HP is being changed instantly

the only thing thats delayed is the gray bar that trails the HP as a visual effect

but yea i guess the more i get off tick the better

its the only thing running on tick

[frosty heron]

Won't matter tbh, depend on what u r doing

This is pretty lightweight imo, don't optimise prematurely

If something needs to happend every frame, do it on tick

Eg attribute trails

@outer terrace actually I read your blueprint weong

I don't know when the delay is called, I thought it's called every tick

[outer terrace]

nope. the delay is only called when i recieve my broadcast from OnHealthChanged

[frosty heron]

Ahh ok

That's fine then

And the video show that everything in order too

[outer terrace]

i set my Attribute value.. than after 2 seconds i set a target attribute.. than on tick i have a bool if my attribute and target != it interps until they ==

[frosty heron]

Probably near equal for floats if you run to any hiccup by any chance

[chrome pumice]

Guys im thinking abt making whole maps on blender, should i use complex collision or is there any downside?

[keen iris]

Anyone know how i can fix that?
when there are two blueprints I can't click one of the buttons, when there is only one left I can click it, what's the problem?

blueprint: https://blueprintue.com/blueprint/f7a_pnue/

[dawn gazelle]

You don't want to make whole maps in Blender. A lot of your geometry is likely to be reused which means you could leverage things like HISM and LODs in Unreal to reduce the performance impact, but only if you use mesh "parts" and build your map within Unreal. If you have your entire map built in Blender, then all of the geometry of that map will always be considered fully visible and not be able to use LODs or HISM.

If you're not doing gameplay stuff, and are only doing renders or something, I don't think it would matter much. If the map is very small (like a small indoor room of a house) and doesn't have a lot of repeating details, then it probably wouldn't matter either.

[supple dome]

hmm.. i think the input action nodes may be consuming input, click it and check the details panel, disable consume input

[noble ledge]

I have an array that is of type WBP_MyWidget. When I drag off of it and type get I only have the option to make a copy. What dictates whether or not I can get a ref or copy?

[chrome pumice]

Thanks !

[frosty heron]

You are getting a copy of the memory address

It's going to point to the same object

In bp land, don't think you can get ref. Everything is pass by value

[bitter star]

Something like this seems to work but I get a bunch of Blueprint Runtime Errors. Does it look correct?

[lunar sleet]

If you get errors, then no, it is not correct

[bitter star]

Ok, let me rephrase... do you see where the errors could come from?

[frosty heron]

showing the error log would be helpful

[warped juniper]

Hey there everyone, is there a function or node that can return a specific function or event based on certain criteria within an array?

Basically I have an array with a set number of values.

It's a system similar to a morse code... I'm using ints. 1 is dot, 2 is line, 0 is empty.

[frosty heron]

TMap for pairing values

[warped juniper]

Oh thank you... I'm not too familiar with TMaps so I didn't think of them

How do I use them exactly?

[frosty heron]

you make a pair for 2 types of variables

in your case it's <int, string>

[warped juniper]

Ah sorry, I'm not exactly returning a letter off of this...

[frosty heron]

where int is the key and string is the value

[warped juniper]

This is morse code in input for the sake of gameplay.

[bitter star]

Hope this helps

[frosty heron]

Yup, it tells you what the error is

[warped juniper]

This is the current setup I'm talking about.
The array stores the last 3 values received, reset every few seconds by calling it again with a retriggerable delay.

[frosty heron]

Gas1Unit , Gas2Unit and what ever listed there are not set yet when you are trying to access it

[frosty heron]

I can't connect the dots

[warped juniper]

Basically each array combination returns its own assigned event.

Or function, whatever.

So an array of [1, 0, 0] exectures Function A, an array of [1, 1, 0] returns Function B, and so on.

[frosty heron]

probably just use branch and call the relevant function then

[dawn gazelle]

In other words, you're trying to do a combo system?

[warped juniper]

Is there a clean way to do a branch like that?

[warped juniper]

Yeah, pretty much.

Are you familiar with Magicka?

[dawn gazelle]

Nope

[warped juniper]

Are you familiar with dota

[tame grotto]

A wild thought - you can store as strings and make a SwitchOnString gate

[warped juniper]

Hm, how exactly would that work?

[tame grotto]

You cam easily convert back and forth string and int

[bitter star]

I'm using the BP to spawn 1 gas can or 2. When there's one there cant be 2 and when there's 2 there cant be one. Then I have another command to destroy all actors. Where should I place the "set" so I dont get these errors?

[warped juniper]

How do you convert an array of int into a string, though?

[tame grotto]

Where do you get your input numbers? From keyboard keys?

[warped juniper]

The input numbers are assigned on button hold and tap.

1 is tap, 2 is hold, and 0 is for no input.

[frosty heron]

that's on you to do , as in you have to think about your design.

All I can say is you are trying to access it when it is not set. So set the variable where it make sense.
You have to think on when to set, when to access and when to dereference them

[tame grotto]

So you do string append each input and count to 3

[frosty heron]

Used to be immortal, but what about dota?

[warped juniper]

The system I have here is similar to Invoker.

Except that instead of 3 inputs with order being ignored, this is 2 inputs that care about order.

[frosty heron]

Why do you have reset to begin with, just wondering

when the input is pressed, it should just get rid of the oldest key and add the new one to first index, then move the rest by 1

[warped juniper]

The reset is so it can be rest after X seconds of not performing an input.

As well as resetting it manually if I need to do some debugging.

[warped juniper]

Yeah that's waht it's doing, currently.

[warped juniper]

I can't find how to do that, context sensitive search shows nothing

[tame grotto]

Thats the node. Ignore the circle, took that from google

[warped juniper]

Ohhh I see

Hm how can I just use that one?

I'm using for each loop appending everything one by one.

[tame grotto]

And then you just make switch on string gate with hardcoded combinations

[warped juniper]

Yeah that seems good.

Given the system I have hardcoded combinations isn't bad at all.

Since that's the whole mechanical point of this system.

[tame grotto]

You make a string var append to it each loop and after 3 loops you just reset it

[warped juniper]

I ended up just doing this.

[tame grotto]

You could do it more versatile like for each loop with break where break on certain loop count exits the gate and resets the string

[warped juniper]

Hmm, what are the advantages of that method?

[tame grotto]

You could store more numbers in array and its more automated

[warped juniper]

Wouldn't for each loop be more expensive?

Though if I wanna add more inputs it would get sorted automatically, so that's an upside.

[warped juniper]

This 100% needs me to make a string variable, right?

Ah, also how can I make that string based gate?

[tame grotto]

Its negligible on such small scale and as you can see it'll be more scalable if you add more inputs

[tame grotto]

Switch on string in flow section

[tame grotto]

Yep for the gate switch

[warped juniper]

Alright, got it.

I'll tweak it

@tame grotto Okay, here's the current status

[tame grotto]

Looks good but if you have an array of more than 3 you'll need a loop with break

[warped juniper]

Currently this is what makes the array, it cannot hold more than 3 values currently.

Huh, nothing is resetting the string

It's when I call the function to clean it up and only get the current array

[tame grotto]

Yeah my bad

So all is left is that gate

[warped juniper]

Yeah way ahead of you

Yeah this looks ugly as sin

Sadly it's still the most efficient solution I found, hah

[tame grotto]

In cpp you could do it nicer with a pointers but it'll do as long as it works anything goes. You can collapse the nodes after that so it won't look this bad on main graph

[warped juniper]

I'm not opposed to adding a bit of CPP for efficiency and clean running...

Currently, maybe not given this is a concept...

[tame grotto]

It's always better to prototype in BP tho

[warped juniper]

Yeah of course.

[tame grotto]

And I'm sure theres a much nicer solution somewhere the longer you think about it 🙂

[warped juniper]

It's just much faster.

Mind telling me about those pointers though?

Also, how do you reccomend approaching the character casting a different spell on each case?

Should each spell be components stored together, or maybe just functions stored in the player

[tame grotto]

You just make an int32 pointer and then fill it depending on outcome

[tame grotto]

Making an actor component to store all the spells in one place its a first

And store all spell casting functions in it

[warped juniper]

Hmmm yeah

Like currently I have a simple fireball projectile actor

It has the standard properties and all

Thing is I also need to modify that projectiles qualities.

This lets me recycle spells between players and even enemies, with unique properties for each to differentiate them.

[tame grotto]

For some generic reusable formulas you can make a blueprint library

[neat stream]

Anyone got a second to check over som BP code i have for healing and anti-healing? I want to make sure I'm on the right track and need someone to double check my math.

[warped juniper]

Well just post a picture or blueprintue link and someone should give their two cents

[warped juniper]

Not enough of a coder to know much of that, sadly

[tame grotto]

Its an asset you make just like regular blueprint. Basically a collection of functions that can be accessed from any actor without the need of casting

[short ivy]

Thanks a lot! I think this is not really what I need at the moment though. My problem needs a different solution apparently. A bit of context, I am trying to mount a pak at runtime on server and clients and make it replicated so that all players basically know that this mounted pak was basically the same one and that any asset of it spawned will be displayed correctly as if an asset from the base game pak was spawned. I could send you some logs of the packaged build if you want to dive into it as well but I would prefer not doing it in public channels. Let me know if you are open to that.

[warped juniper]

Huh, that's pretty interesting... How do you set that up? Sounds very useful.

No need for making it a component either?

What's the difference?

[tame grotto]

Nope. The downside it cant have any variables of its own. You right click in asset panel and iirc it'll be in the blueprint section

[warped juniper]

Huh... Not sure why should I use components over it then.

[tame grotto]

It cant have any variables so mostly like basic calculations

Kinda like simplified cpp library

[warped juniper]

So for instance, a formula for damage falloff on weapons and whatnot

[tame grotto]

Yep you just make a function there with inputs for damage. Its a very handy thing

[neat stream]

Thanks. I didn't know we could post pics. I'm trying to create a stacking disease system that lowers incoming healing. Each stack of disease (disease multiplier) = -20% incoming healing.

[pure heron]

What the hell am I doing wrong?
I construct a new viewmodel in the gameinstance and add it to the collection, I do a global binding in the widget, but when I try to use this collection the cast just fails...?

Just straight up cannot find this thing

[warped juniper]

The clamp makes it so there is always at least 1 stack of disease. Is that intended?

Also the screenshot is really small, I can't properly ready anything

[neat stream]

It comes after a check to see if there's greater than or equal to 1 stac. It's a redundancy that also clamps the stack to max stacks. I hope this is better.

[dawn gazelle]

This part seems like it has some unnecessary math. You shouldn't need to multiply by 100 and divide by 100 and then store this as another variable. You should be able to use "Disease Multiplier Total" directly.
Let's say your disease multiplier is 0.2
1 stack would mean Disease Multiplier Total = 0.2
100% can be represented as 1.00 so all that would need to be done is 1.00 - 0.2 = 0.80

2 stacks would mean Disease Multiplier Total = 0.40
1.00 - 0.4 = 0.60 etc..

Otherwise, the rest of the math does look correct.
You're multiplying incoming heal by the Disease Modifier, so if we use the 2 stack example and an incoming heal of 1000, you would get an effective heal of only 60% rather than the 100%, equating to 600 for your "Heal Amount".

[neat stream]

So more like this

[dawn gazelle]

You could also just set Final Heal Amount to 1 if you have <= 0 for the amount check, the lowest value possible would be 0, so it would always be 1.

[warped juniper]

@tame grotto Sorry for the ping, but you've been a massive help so far... So I have one last question for the day.
How can I make a projectile spawned by X actor gain access to a set of variables such as damage, speed, instigator, etc...

All I can come up with is methods that end up as dependencies, which isn't good.

[dawn gazelle]

You want the projectile to read the values from X actor or coudl X actor that is spawning it feed in those values?

[warped juniper]

I currently have a function as part of a component that spawns the projectile

I want the and properties of this projectile BP to vary from actor to actor while behaving the same way

[neat stream]

Well now I feel dumb. Lol. I over complicated the hell out of it.

[dawn gazelle]

So have your component have those properties, this allows you to set those properties on any actor that has that component.
When spawning your projectile, you would then feed in the value currently stored on the component into the spawned projectile - this can be done by marking the properties you want as "exposed on spawn" which will then give you pins to input values on the spawn actor node.

[warped juniper]

Currently it's a fireball spell that creates an explosion on the impact point.
The values in question that I want to edit:
Fireball gravity
Fireball speed
Fireball damage on direct hit
Explosion Damage
Explosion radius

Ahhh alright, thank you for that

@dawn gazelle I need to reload the Spawn actors on the nodes to reflect the change... Is that normal?

[dawn gazelle]

Yep, just a refresh of the node

[neat stream]

Cleaned it all up. Thanks for the help.

[warped juniper]

Alright. Thanks for thee help! Such a small thing and yet so important...

[gentle urchin]

Cant you skip the branch, do the regular math and add a max(1, calc) clamp to it

Unless i read the math wrong 😅

So you can set Modified heal amount directly

[neat stream]

Something like this?

[gentle urchin]

Yepp, altho you dont need a full on clamp

Max should suffice

Unless you wanna clamp to max, but max is really current-max ..

[neat stream]

I think I want to keep a clamp. So players can't heal past max hp.

[gentle urchin]

I prefer doing that in the set health function

Thats hopefully in your SetHealth already

Thats the only place it matters

This wont really work anywyas

If you already have 100% health , healing 1.0 more is an overload.

[tame grotto]

No worries. If those actors that spawn a projectile are placed in the world and not spawned themselves, you can mark needed variables as instance editables and then adjust each one manually in the world in details panel

[warped juniper]

Someone helped me out on that, regardless, thank you very much! You are a lifesaver...

[tame grotto]

Was happy to help✌️

[warped juniper]

Yeah I get a bit desperate given I have 1 month and other stuff to juggle...

First idea turned out to be less of a dud, and more "this needs way more polish and experimentation that I have time"

It was a Super Mario 64 meets Metroid kinda thing... Shooting without a reticle feels bad, and having automatic aiming / locking isn't what I wanted to have either.

Making it a top down thing could be a possibility, top down platforming is actually an interesting concept worth exploring, but a bit too revolutionary for what I need to achieve right now.

[keen iris]

@supple dome Thank you so much ❤️

[light glen]

is it possible to diff two blueprints? i want to see why what i did wrong with my implementation from an example

[sick sky]

using version control you can

but i dont think thats what you are doing

[quiet pasture]

hi all, I'm trying to use "set physics velocity" to launch a grenade mesh, but I found in about 1 of 10 cases, the grenade falls directly to the ground with the same velocity set as in other cases - does anyone know how to fix this?

[lethal pollen]

Do you know where is the documentation of the Create Widget Blueprint's node?

[trim matrix]

Is there a way to set if an object is a shadow caster?

[frosty heron]

Set what?

[trim matrix]

Get an object in the world

and change if it casts shadows

[frosty heron]

Change what?

U want to toggle the boolean?

Get a ref to the object and get the property bCastShadow

Not sure if u can toggle that tho, might not be something u can change at run time

[trim matrix]

Gotcha yeah, that's the idea

I basically just want to get tagged objects from X distance from the camera, and disable shadows on those tagged objects past that distance

[nocturne basalt]

devs, how to play a few timelines in row, one after another?

[lofty rapids]

maybe put them on seperate events and run when timeline finished

[thin panther]

I'd use the timeline node rather than directly using it's component though

[spiral ridge]

Try to put delay(equally timeline) between them.

[nocturne basalt]

thanks, it really worked

i thought it's gonna work without any extra code, events and delays(

[lofty rapids]

the issue is most likely the play doesn't wait, it just play then move on

[dark drum]

Does anyone know if there are any debugging tools that show all event dispatchers and any delegates bound to them? I want to make sure I don't have bindings that are lingering when no longer needed.

[frigid summit]

hi guys is there alterntive to the set half size node that doesnt make my charcter stop moving after the roll

[forest summit]

https://i.imgur.com/lsAm6EQ.png
https://i.imgur.com/KgElzQ4.png

You can use this to find refernces to individual diaspatchers

[dark drum]

I was referring more at runtime.

[forest summit]

ah ok, misunderstood

[remote meteor]

to verify, you could use VS local/autos during breakpoints/debug to check whether the delegate still has any object/function reference, alternatively you could have just call unbind all event if you dont want it anymore.

[pulsar vigil]

Hey guys quick question, any counter indication about making a structure in a structure with a map in it ?
Structure inception is that a bad thing ?
Correction its a map that contain a structure wich contain a map is that bad ? will i trigger another big bang ?

Chat GPT answer satisfy me

[frigid summit]

plz help : (

[silent drift]

Hello! What is the main difference between using a component VS doing a parent where I do certain things?

The reason for my question is that I have:

Shared enemy, mini-boss and main boss as three different category types (and I will probably add some more level specific ones as well). These are all based on the "BP_Character_Enemy_Base" and then I have BP_CE_Shared_Base, BP_CE_MiniBoss_Base, and so on.

I have this so I can make them react to different things in different ways and such things when the player shoots on them, and of-course they have a different BT structure and complexity depending on which one they fall into.

Currently to deal with health and damage, I have a BPC_Health_Base, and then children BPC_Health_Enemy_Base, and BPC_Health_Player. And from the BPC_Health_Enemy, I have children depending on the enemy type, BPC_Health_Shared_Enemy, and BPC_Health_MiniBoss and so

I'm wondering, if I should rather in the BP_Character_Base (the base for ALL my characters including the player) add the health to them, and then in then in the BP_Character_Enemy_Base I do what it is different for the enemies and I make a "base way of dealing with taking damage", but then I can over-write it per character if I wanted. Meaning if I have two different bosses they can handle health differently (e.g. one of them might get stunned and get damage, vs one that will never be stunned and get damage).

With my current setup this would be a pain.

Is there any big negative to do this inside of the character BP's instead of inside of a component? I feel like the biggest positive for the component is that I could attach it to anything. But in theory, I could also just do a interface and let that deal with it? + Are the any performance positives / worries with any of these solutions?

Sorry for such a long message, but I was lying a long time this night trying to figure out the better approach and decided I need some help on this. 😄

[silent drift]

Why do they stop? I don't see any reason why they should? But, I also don't see that you are resetting the height after anywhere? If that would matter.

[left badger]

I forgot the shortcut to create a branch for the blueprints. Can someone remind me?

[lofty rapids]

something like hold b, and click ?

[left badger]

@lofty rapids mvp thanks

[limber parcel]

component is something you want to use across multiple actors with different parents

example: i made the health part into a component because i want to use it not only on characters

[remote meteor]

components are mainly use to separate individual features that one actor should have into its own section to achieve a few things

• Reusability, ensuring similar behavior across many uses.
• Condensed, all in one place so you could "see" all of them without disturbance from other features
• Enabling multiple collaborators to work on one actor, as they may just work on the component, and not the actor.

HealthComponent is probably something that will handle almost exactly the same in every entities in the game (e.g. subtracting floats, damage done eligibility, modifiers, callbacks on change). It probably wont be really different across entities. What could be changed are usually stuffs that happens before or after the health calculation, for those cases, having options/configs in the components or exposing a delegate to the actor bp would solve the job, allowing the actor bp to overrides on each child (e.g. different reaction when dying, boss %hp mechanics).

Polymorphism on the other hand is very much more on OOP designs, where each entities has features or behavior that shares among its children. The children could extend or override them to suit their own use. (e.g. Character can jump, Item can be picked up)

[limber parcel]

personally i try to put everything into components and have the least possible amount of stuff going on in the character itself

[cinder tree]

Are the checkboxes for replication client-side predictive & server side reconcilable?

[silent drift]

Okay! It sounds like I should keep my current flow, and make a new child component for each type rather than adding it to the character?

[remote meteor]

usually you dont make child components

[silent drift]

FYI: "Polymorphism on the other hand is very much more on OOP designs, where each entities has features or behavior that shares among its children. The children could extend or override them to suit their own use. (e.g. Character can jump, Item can be picked up) " - Yeah, that is where I'm mostly coming from with the OOP design and such. 🙂

Hmm, okay,

Then I'm not sure what the best solution is right now. 😄

[remote meteor]

what you do is you add the components to the base actor

and on the child actors, either change the component's config (can recieve damage, can heal, damage recieve multiplier), or handle differently when there is a delegate callback (OnHealthChanged, do something different on each child)

[silent drift]

Okay, hmm, I'm still not sure how I want to approach this based on this. 😄 I mean I could still have a health component and then send certain delegates like you said. That is a fair point. Then I would still only have "one" component per type and be able to deal with this.

[frigid summit]

i dont know why it stop

[silent drift]

I'm just not sure if the polymorphism isn't easier to maintain. 😄

[limber parcel]

but when ure using a component already, do you even need delegates?

[frigid summit]

and yes i reset it after the roll complete but still stop

[lofty rapids]

if you don't change half height, does it still stop ?

[remote meteor]

if we take HealthComponent as an example each entities that uses health component may handle differently when their health reach 0, some dies, some dont, some destroys, some triggers some event. these are the times where you use a delegate to call in the HealthComponent to inform the actor bp that "hey, this has happened, do you want to handle something?"

[limber parcel]

its completely different use cases imo

[frigid summit]

if i dont change the hight at all it will block my way without rolling i mean the obstacle

[lofty rapids]

i mean to see if it's that setting or something else stopping you

its possibly another reason

[remote meteor]

in this case, we are separating the general tasks that a Heath feature should have into its own component, if there are anything unique things that should happen based on what entity the actor is, the actor should be responsible for knowing what it is.

[frigid summit]

i dont really know im changing the hight just to make the obstcle dont block

[limber parcel]

yeah but the component can just call a function on its parent instead

[silent drift]

Well, let me give an example what the use-case is.

I have two projectiles fire and ice.

When I hit the enemy with fire, nothing happens.
But if I hit the enemy with five ice projectiles, it's freezes
then when I shoot fire it will explode and instant die.

However, for other enemies they will just take different amounts of damage (I have a damage multiplier I use to check this). So fire deals 10 hp damage and ice 5 hp damage.

So some enemies should be stunned, and others shoulkd not, etc.

And it will be different depending on the enemy type.

That is why I wonder if the component approach is a bit "too" limited. but I honestly don't know.

[remote meteor]

then you couldnt use it on any actor you want? you need to know the class type to call a function, that defeats the purpose of component, and also circular dependency is bad.

[lofty rapids]

your saying that code makes it stop, it's possibly not that node

[limber parcel]

but you already have circular dependency when u attach the component basically

[remote meteor]

uh, the components will have 0 idea who it is being attached to lol

[frigid summit]

yea i dont know whats the cause i jusst roll over the obstacle and the charcter suddenly stop and the animation still going for run

[limber parcel]

but it still shows in the size map

[lofty rapids]

is your walk/run in a blendspace ?

[frigid summit]

i mean like this

[frigid summit]

hold on let me check

yea it does

[remote meteor]

in this case, what you need are some configs, usually i will have a StatusEffectComponent for these kind of stuff, you have stuff like whether it is resistance to certain elements, whether they should just take damage instead of applying the status effect, etc etc

[lofty rapids]

is your character stuck on that glowing thing ?

[frigid summit]

no its stuck wherever the obstacle that i roll over

[lofty rapids]

does it snap back or the animations are all smooth ?

[silent drift]

Hmm, interesting.

[frigid summit]

i dont know how to know this

[remote meteor]

you could integrate them in the health component, but i usually separate them

[lofty rapids]

when you roll over the object, are you stuck at the spot where you started or finished the roll ?

[frigid summit]

yes

[lofty rapids]

hmm

[frigid summit]

i finish the roll and it get stuck

[limber parcel]

thats not really a question of which one is better, polymorphism or components, i would use both in this scenario

[silent drift]

Yeah? How would you use both?

Sorry as in how would you suggest to combine them

[limber parcel]

firstly i would use polymorphism to make the different projectiles, and i would use a component to handle their impact on actors

[frigid summit]

i set set half hight of capsule because someone suggested me this

[limber parcel]

so if my projectiles hit an actor, they check if that actor has a health component, and then interacts with it

[silent drift]

I think I will need to go back and think through this design a bit, and how to best do it. But is there any performance difference between the component vs the polymorphism that I would need to wory about?

[lofty rapids]

ya but what i'm saying is that may not be whats actually causing the stop, if you could show a video or a gif or something of what it looks like and also some code maybe someone might spot something

[silent drift]

That it already does. If check if it has a health component, and then does apply point damage. 🙂

[frigid summit]

ok i will

[limber parcel]

if you need more complex interaction you make an interface

[lofty rapids]

if your using a blendspace based on speed, it's weird it would be running

does it run when you don't press the key ?

actually what does the anim bp look like ?

it may be the play montage also hard to tell without seeing

[silent drift]

I mean it sounds like the component is the better approach, from what I hear from you guys. 🙂 So I will liekly stay with that, but need to figure out how to make it easy to add / stop certain actions depending on the enemy. I assume having tons of "settings" is the best approach based on this. E.g. CanBeStunned, if yes, it will get stunned after X hits and so on.

Rather than adding more code to the characters BP's.

[limber parcel]

yeah u can handle all that stuff in your health component

[frigid summit]

ok

[frigid summit]

its the default third person anim bp

[lofty rapids]

looks like your stuck in the floor

notice your roll is a bit low

sticks you into the ground

try jumping out

[frigid summit]

i tried it didnt do anything but i can switch lanes still

[lofty rapids]

well your stuck in the floor

[silent drift]

Yeah. Just need to add quite a few settings.

[limber parcel]

my component looks like this now xD

you can do a lot with gameplay tags

[frigid summit]

why this only happens when i change the hight

[lofty rapids]

#animation may know why it's doing that also

[remote meteor]

you could think of it in 2 parts, applying effects (having some sort of tags or identifier that the effect is happening), and reacting to effects (reading the tags or identifier and reacting accordingly).

The following bracket'd parts are reaction to effect.

Fire projectile applies a Melt Effect, (but its condition is Freeze is required on the Target)
Ice projectiles applies a Slow Effect, (when Slow Effect stack reaches 5, it Freezes its target)

When Melt Effect happens, (depending on the config either it would be instant death or take a multiplied damage. If stun in a unique behavior that a unit has, you can use a delegate to let the actor know that Melt event has happened, and it should stun itself. or you could just have another config to say whether should stun on Melt)

[frigid summit]

ok ill ask there

[lofty rapids]

thats why i said to just disconnect that node and see if its actually that one thats doing it

[silent drift]

Thanks to both of you! I will try and fix this.

Regarding GameplayTags though, don't I need to check for changes to that inside of a "tick event"?`There is now event called "GameplayTagchanged or such right that I can use?

[limber parcel]

yes

[remote meteor]

uhh FGameplayTagContainer?

[limber parcel]

you can use gameplay ability system

[remote meteor]

i dont recall they have any sorts of changed delegate

[limber parcel]

no but GAS handles a lot of that stuff for you

[remote meteor]

that is only a thing in the UAbilitySystemComponent, because adding/removing tags is through the ASC, so it is possible to have these delegate

are you using GAS..?

[remote meteor]

But is there any performance difference between the component vs the polymorphism that I would need to wory about?
Nope.

[silent drift]

Thanks! And currently I'm not using GAS.

I have been looking into it, but not really gone into it

Is there a way to make a delay happen, but then also allow the delay to be interupted?

My use case is that I have a UMG conversation between two characters. When one character speaks, a flipbook starts playing the selected animation. I only want that animation to play for a short while (the delay) while the character is speaking, then revert back to the default pose.

However if the player skips over the dialog before the delay finishes, I want it to cancel the delay/revert to default pose, so that it doesnt interupt the new post that was intiated by reading the next dialog line.

[frigid summit]

i think there is delay with break

[remote meteor]

its called a ⏲️ ||Timer|| !

[mortal jay]

Ooo, this is probably what I want. Thanks 👍

Might sound like a silly question but how do I basically copy/paste an event? obviously it wont let me but how can I call an event in multiple places an tie it to other functions so one event can fire 10 things with out having to drag a gigantic noodle across my graph

[frosty heron]

why do u want copy paste an event?

[remote meteor]

you make an event that call that 10 other events

[gray lantern]

😭

Ahh well can do that

[remote meteor]

then you call the "thicc" event when you want to call those 10 events

[gray lantern]

I suppose its cause if you copy/paste it's not clear then which one fires first

that makes sense now

[frosty heron]

runs from left to right

it would be observable what run first

add breakpoint if need be

[gray lantern]

no but I mean, that's why they don't let you just copy/paste lol

[frosty heron]

u can copy paste event, just not with the same name

because then, it don't know which to call

[gray lantern]

All good I'll do my super event 💯

[mortal jay]

Am I using the event timer correctly? When watching it while playing, I can see it hitting the Set Timer by Event node, but I never see the print statement show up after that.

[remote meteor]

set Time to tell it to run after x amount of seconds

[mortal jay]

Shouldnt it fire immediately if set to 0.0?

[remote meteor]

hover the node

0.0f means canceling the timer

[mortal jay]

Ahh

thanks 🙂

[remote meteor]

if you want it to run immediately, call the function immediately right after

[mortal jay]

I dont want it to run immediately, but was doing that for testing purposes. Makes sense though, thanks!

[remote meteor]

and to "cancel" it, cancel from the FTimerHandle that this node returns.

[limber parcel]

i was using it for some time, but it doesnt make much sense in a blueprint only project so i went back to using my own system

[mortal jay]

Oh, one more question. Do timers work when the game is paused? Guessing that might be my last issue...my UMG conversations happen while the gameplay is paused.

[remote meteor]

oh uhh....

no unfortunately 😅

[mortal jay]

Ha, dang. No worries though. I've been meaning to implement a psuedo-pause for that anyway
