blueprint

[lofty rapids]

thats your problem

your using local variables to your game state

i think you need to watch blueprint videos a bit imo

idk how to explain it any simpler

literally what i posted is what you need to do it's super easy

it just requires you to understand your variables and whats going on a bit

[chilly thicket]

its just a communication thing tbh im not really interpreting what your typing and converting it to what im looking at, i defiantly need more knowlege but just need the direction in a different format personally

[lofty rapids]

watch a youtube video on how to use game instance

and try to apply it ?

[devout yarrow]

am i asking this in the right place?

[lofty rapids]

tbh most often with a plugin you would hope they had they have there own discord

or some sort of contact

[chilly thicket]

i have a couple udemy courses im working thru but for this specific project this is my last bug before its completed so i was trying out some different fixes before i have to change too much code around

[lofty rapids]

ya it's literally like 4 more nodes, and it's actually 2 nodes just repeated

[chilly thicket]

i did what i thought you said and i was still having the issue but i couldve dont it incorrectly

but again im still new so i couldve misenterpreted

[lofty rapids]

you definately misinterpreted, i just don't know how

^

anyway this is all you need to do

and you don't need to do anything else

to fix this problem

[chilly thicket]

i did that for the objective array varaibles and i lost the objectives in gaem entirely

[lofty rapids]

so most likely you have defaults

and you need to transfer them

but show what you did anyway to see if it's correct

[lofty rapids]

right, because your gamestate array probably has all the stuff in the array to start correct ?

and your game instance one is probably empty

[chilly thicket]

it is

correct on both

[lofty rapids]

you need to populate the gamestate stuff on the game instance now

you can copy it at the beginning of level1 as well

but you just need those defaults in there

and your good to go

[lofty rapids]

you also showed just one function ? make sure you changed it in both

[lofty rapids]

yes like that

you get the defaults in the array ?

hopefully you didn't have too many objectives to set up

[chilly thicket]

and this is in my instance

it doesnt they dont show at all

hmmm

[lofty rapids]

any error ?

[lofty rapids]

ya thats the problem

the instance reference isn't valid

do you know what i mean by that ?

[chilly thicket]

probably not lol

i think the reference the arrays come from?

variable

[lofty rapids]

the game instance reference

where do you set that ?

[chilly thicket]

i dont think i do set it im just getting it, in my gamestate atleast

i have to set it in my game state?

[lofty rapids]

did you see the picture i sent you 2 hours ago ?

lol

because thats what you need to do

yes in your gamestate

[chilly thicket]

like this?

[lofty rapids]

yes

[chilly thicket]

i just ploped it in her

[lofty rapids]

try that

[chilly thicket]

https://tenor.com/view/always-sunny-frank-oh-my-god-i-get-it-gif-22328165

[devout yarrow]

ah ok, I will see

[chilly thicket]

youre the fucking goat!!!!!!!!!!!!!!!!!

[lofty rapids]

see it was pretty easy tho

once you know how it works, things are so much simpler

i like the game instance, it's the only thing that can do that

[chilly thicket]

thanks alot! and yes it helps alot to work thru an issue that was actually really informative for me i really appriecate it. check out the game im gonna send you a key in a couple days when they come in!

[graceful sage]

I'm still having a hard time on how to do my money depletion/building system

I've moved my depletion to money and money to an actor component attached to controller

{
    Super::TickComponent(DeltaTime, TickType, ThisTickFunction);

    if (Money != MoneyTarget)
    {
        Money = FMath::FInterpConstantTo(Money, MoneyTarget, DeltaTime, 50.0f);
        if (StatBar)
        {
            StatBar->SetMoneyText(FText::AsNumber(FMath::RoundToFloat(Money)));
        }
    }
}

I'm not sure how I should do the progress and determing when its ready

I know the money at start is wrong but I'm just not sure how to handle this

I suppose I need a variable to adjust the interp speed to but not sure how to determine the speed

[graceful sage]

anyone?

[tawny hedge]

what's the best way to filter a single hit per actor with multi sphere trace? currently I get multiple hits per actor. Is it just a matter of filtering the hit results?

[graceful sage]

why not use single trace?

[tawny hedge]

because it doesn't give the same shape and I need multiple actors as an array but I need only 1 hit per actor

[graceful sage]

id say youd just loop through the results then

[steel shadow]

Try and set things up so that you have one component per actor of the object type you trace for

[celest crown]

Does these BP lines have any name? I know the type of them, but are they named anything other than lines/exec lines?

[dark drum]

I call the white line the exec line. Any other colour, var lines. Blue being objects, green floats, purple class, orange transform, yellow vector, grey blue rotator etc...

[celest crown]

alright thank you

[spark steppe]

they are named spaghetti

[lunar sleet]

also known as noodles

[dry wave]

Ok I have a strange issue my code works fine testing in editor bot is bugged whith the built version, I'm not sure why

[dark drum]

You'd need to show your code and describe what should happen and what does happen. Someone might be able to point you towards the possible cause.

[dark drum]

Does anyone know why 'Remove From World' gets called when closing the PIE window? I would assume it should be the 'End Play In Editor' instead. I am using level streaming so i'm not sure if its a bug with that.

[formal topaz]

Hey guys, I am trying to make a similar mechanic to deadeye in Red Dead Redemption. I used billboard components to set up the marker placement tracing. Evertthing works great sxcept when i shoot the bullets it shoots in all the markers instead of shooting one by one

how do i fix it?

[lofty rapids]

loops run pretty fast

[formal topaz]

speed can be fixed later on. just need a fix for spawning multiple bullets in the location with the loop. I want them to appear one by one

[lofty rapids]

well i'm saying thats why they shoot at once, a loop runs fast

it looks like at once, but really its one by one, just fast

you can set some delays based on the index

to slow it down a bit

or you can make a macro that is a foreach with delay

[formal topaz]

ah i see. let me try it

[gusty crater]

im making a wave spawner, have a datatable with my enemies, and i set a weight to them. How can i use that weight to then decide which one is picked? i cant work out how to set it up

[lofty rapids]

so you want a weighted random ?

[gusty crater]

i think so. certain enemies unlock at certain waves. And i want a heap of "grunts" some elites etc...

[lofty rapids]

yes a weighted random is great

[gusty crater]

i always want atleast 1 elite at certain wave intervals too

its hurting my brain xD

[lofty rapids]

i don't think weighted random can do that, that would be something you spawn other then

you would just always spawn an elite, after or before you spawned random

but you can do random with weights it's not too bad

[gusty crater]

hmmm, or should i do them a set amount, then just multiply per wave and round down or something

[lofty rapids]

do you know anything about programming languages ?

[gusty crater]

only basics, mostly use bp's

just dabbled in a few here and there

[lofty rapids]

weighted random is the way to do it if you want to be able to increase/decrease rarity

[lofty rapids]

i've never used a data table

i use maps for weighted random

[gusty crater]

i can move it to a map pretty easy

[lofty rapids]

so if you have a map, like string to struct

then you can get a random, and pull the struct

which is better then what i did, which is use two different maps

lol

[lofty rapids]

function weightedRandom(items, weights):
  // items: a list of items to choose from
  // weights: a list of weights, corresponding to the items

  // 1. Calculate the total weight
  totalWeight = sum(weights)

  // 2. Generate a random number between 0 and totalWeight
  randomNumber = random(0, totalWeight)

  // 3. Iterate through items, subtracting each weight from randomNumber
  //    until randomNumber is less than or equal to 0.
  //    The item corresponding to the weight that causes randomNumber to
  //    become less than or equal to 0 is the chosen item.

  currentWeight = 0
  for i from 0 to length(items) - 1:
    currentWeight = currentWeight + weights[i]
    if randomNumber <= currentWeight:
      return items[i]

  // Should not reach here if weights are correct, but handle
  // potential rounding errors.
  return items[length(items) - 1]

this is what the googles says about it

does any of this make sense ?

https://blueprintue.com/blueprint/fb605rdt/

this is my weighted random in bp

i just made it the other day

you basically get a radom number between 0 and totalweight-1 ...

then you check if that randomnumber is les then or equal to the weight at the current spot in the loop, if not subtract from the randomnumber continue loop, if it is then the current item is the selected one

[gusty crater]

legend thanks mate

[lofty rapids]

with that function i find it better to pass in the total

because if you run this a bunch of times you don't want to keep looping over and over to get the total

get the total before the loop, and pass it in for efficiency

what i should of done is just used one map, and set a weight in the item struct

lol

[dark drum]

Another option is to add x number of entries to an array (local) for each item and then use the random array node to get one at random. You do sacrifice precision but for some use cases can be nice and simple.

[lofty rapids]

thats a neat trick

[lofty rapids]

the only thing i worry about is array size

[dark drum]

Yea, i tend to use it for simple weight stuff. Definitely not recommend if you want more complex weights.

[lofty rapids]

makes sense

[dark drum]

If you wanted a 1% chance you'd need 100 elements which might not be great. If you're only interested in 5% you can get way with 20. If that makes sense lol.

[lofty rapids]

^ for sure

[dark drum]

Random weight stuff can get complicated at times. I was looking into random loot once and damn. The moment you add rolls as well. 🫣 It can become its own system.

[lofty rapids]

i've used it in a few projects, i like the ability to just adjust the weights and it adjusts what spawns

and how often, it's really perfect it you have say common, and rare items

i wrote one in c++ and one in blueprints

the c++ code is actually much simpler looking

[dark drum]

I can imagine.

It can be nice would you have something setup for random weights though.

[lofty rapids]

it's great actually, way better then just a random number

[dark drum]

I went down the root have having it as objects. So you create a 'Loot' object, pass in the data and it has the relevant functions to do what it needs to do.

This allowed me to change how its handled in different scenarios more easily.

[lofty rapids]

so you could pass it different loot setups ?

i just used a BFL and made a function

[gusty crater]

what if my array ends up being like 300 long? is that big in the scale of things

its endless waves, so will keep increasing until the game cant handle the fps anymore i guess xD

[lofty rapids]

if your just picking a random item 300 is pushing it but not too bad

bp loops are reiculously slow imo, you may if you can want to offload this to c++

it will handle 300 np

[gusty crater]

id be calculating the weights til it hits 0 and picks one 300 times. i can just get the total weights once though

[lofty rapids]

but i would try it in bp

[gusty crater]

the wait time is fine, as i can delay the wave starting by 10 seconds or something

or have it calculating the next lot of enemies whilst the players are fighting the current lot

[lofty rapids]

unfortunately if you pick a weighted random you need to loop through them all

but if you break out or return when you find the one, it could make things faster

[gusty crater]

i just dont want to have to define every wave, i dont mind doing it for say 30, which is when that level will technically end, but then i want an option to play on until they die, which could be 150 waves or whatever

thats why i was thinking weighted

[lofty rapids]

how many different types will there be ?

for instance you spawn 300, but out of what pool of enemys ?

[gusty crater]

still unsure, maybe 20?

[lofty rapids]

thats 6000 execs worst case scenario

thats quite a bit

i would definately suggest using c++ tbh

but if you can offload it like you mentioned thats good

but also the loops can crash at a certain point depending on how long they take

you'll get "infinite loop detected" in bp

[gusty crater]

mmmm

[lofty rapids]

where in c++ it will freeze the game, and continue

[gusty crater]

ive done a tiny bit in c# years ago, but c++ looks like a beast i dont want to touch haha

[lofty rapids]

ya just try it, see whats its like

[gusty crater]

actually i could always keep the current wave, then just add extras each one

that would cut the looping amount down a lot

[lofty rapids]

yes, it would, if you could make that work that would be better in theory

bp just not great with loops the less you have to do the better

[gusty crater]

yeah, i just dont think im ready for c++ yet haha, starting to get semi confident making or working out how to make most the things i want to in bp with no tutorials or anything, but learning c++ would just slow my progression down heaps at this point

[lofty rapids]

i use bp as much as possible

untill i "have to" use c++ for some performance issue

so i understand that

it is difficult to even setup, then program

[gusty crater]

eventually when im happy where the game is, i will learn to optimize and im sure ill have to go down the c++ route for some things

[dark drum]

What sort of weights are you thinking? If you have an array with each possible spawn (one entry each), that's 5% chance to pick any of them.

[gusty crater]

still yet to be determined. Its a rougelite style game

maybe i can have a preset amount, and then just scale it up each wave, and on spawn give them a % chance to be "elite" and that chance will go up based on the current wave number and difficulty

so many ways to go about it, just dont know what is going to feel the nicest

[lofty rapids]

that sounds more efficient then respawning them all each time

i just wonder how random it would feel ?

[lofty rapids]

this is very common in programming, trial and error ftw

[gusty crater]

yeah this is true

[lofty rapids]

what bp is this ?

[dark drum]

Its an actor component on an actor placed in the streamed level.

[lofty rapids]

this is what i found online: "The reason is that PIE is destroying a world instance, while standalone is terminating the entire application."

[merry mirage]

Hoi, a question regarding AnimNotifyStates :
do you know whether AnimNotifies are instanced per actor, per animation or per ActorPerformingAnimation? I seem to run into some issues when I have several actors running the same animation in a level and I was curious if it could maybe be due to how data is instantiated?

[lofty rapids]

does it say quit on standalone ?

[dark drum]

I'm not sure what you mean. I was just playing in a PIE window and when closing the PIE window is triggers the removed from world but I would have thought it would have been the one specific to closing the PIE window.

[lofty rapids]

right, the official docs say: "EndPlayInEditor When the world is being unloaded because PIE is ending."

[lofty rapids]

check the actor, not the component, what does it say on end play ?

[dark drum]

That says 'Removed From World'.

[lofty rapids]

interesting, did you try in standalone, this might change to quit

the docs aren't clear on when they show up, but the brief description would make you think it should say so when pie quits

[dark drum]

I think its a streaming level issue. I believe the character gets unloaded first which means its no longer in the streaming volume which triggers it to unload, despite the fact it should be closing everything.

Or maybe not. 🤔

I really don't fancy having to dig through the source but I think I might need too. 🥲

Although it does seem like something to do with level streaming. The one with the UID is placed in the persistent level and the other is in a streamed level. 🤔

[ornate trail]

How does this get registered? These functions provide property access to the component but are never explicitly called.

[unique timber]

not sure where to drop it so will just put it here
its a plugin that allows for something similar like blueprint to be used in runtime and also be executed there it went open source on github after i talked with the main dev (he stopped selling it, and closed the discord etc.)

[inland walrus]

Anyone know why this is happening?

[faint pasture]

my brother just reuse the getter

no need to drag blue lines all over the place

[inland walrus]

wym haha

[faint pasture]

that makes it awful to read

[inland walrus]

my b someone told me a while ago that reusing is bad

[faint pasture]

they were wrong

it's the same logically, the computer can't tell a difference

but it's a PITA to read

[inland walrus]

They told me it uses more process

I wont do it anymore if thats the case

[faint pasture]

Anyway, you should make your UI more modular.
Make a widget that represents everything about a single room, and then put multiple of those widgets in an outer widget that has 1 entry per room, etc

your widget should be set up in such a way that you can pass in a room ref to it so it knows what to read and modify

make this 1 widget bp that can be told a room to care about, MyRoom

then it can locally do whatever to MyRoom

Say you called that WBP_RoomDetails

the outer widget that's your UI here would just spawn a WBP_RoomDetails and tell it what room it cares about.
Like pressing 1 would go like:
ButtonPress -> if WBP_RoomDetails is valid -> remove -> spawn widget WBP_RoomDetails -> tell it what room to care about -> add to some box or something

the only difference between what 1 2 and 3 do is tell the widget to care about different rooms

like imagine you were doing HP bars

you wouldn't have 100 widgets in some master that manages all their hp values etc, you'd make 1 hp bar widget, and spawn 100 copies of it, feeding each one a different unit to care about

same idea

All your outer widget should do is tell the inner (the details widget) what room it cares about

[inland walrus]

Alright I'll try brew on that and see what I can come up with

How do I seperate what each button is referencing? in local variables?

[faint pasture]

I mean you can hard code for now but eventually you'd fill the button box up with buttons based on get actor of class or whatever so theres 1 button per room

and the button would be a widget you make that has a room ref

for now though, this is at least 3 widgets I think

Blue holds Red and Green, and it manages them, telling them what they care about

when you press 1 the blue widget refreshes the green one with its new room it cares about

Blue is the thing that knows about the 3 rooms, green just knows about whatever room blue said it should be handling

right now the mapping between 1 2 3 and the room actors can be manual, eventually you'll want to get actors of class Room and then spawn and add the buttons 1 2 3 4 5 x x x x etc based on the result of get actors of class

[grim sand]

I'm having a persistent issue with retrieving the world space transform of an instanced static mesh. First pic, I calculate the world space transform and use it to add an instance to a programmatically determined ISM collection.

Then having setup a "get hit result under cursor" function to retrieve the specific instanced mesh world transform, I get a different result. See pic 2. Blue is the location of the tile based on the retrieved data from the calculated position from the logic in the first pic. The pink text is the impact location of the hit result under cursor. Ignore the slight difference on the X as not pure precision from my mouse location.

Does anyone have a clue what might be going on here? I have been stuck on this for a few days now and have narrowed it down to this point. I just don't know from here what the problem might be

In the second pic the Y coordinate is almost 1400 units off from what the transform of the ISM collection reports back

Shit I have been a silly goober

Or at least I think so.. Instead of retrieving the cached value (pic 1), I am retrieving the transform out of the actual ISM collection (pic 2). At that point I get matching transforms. So I guess something in my caching logic is wrong?

Yep, I am caching the wrong value. I don't how or why, but I have confirmed that this is the actual cause of the problem.

But I am only doing it wrong for 2 out of the 4 types of tiles 🤔 Yet the logic for caching is the same for every type of tile

[grim sand]

Simplified the caching to this logic, but the problem persists. I would expect the same result for each ISM collection, but instead I see that for the collections containing the water shallow tiles and the coast tiles that the cached location vector exactly matches the location vector that is present in the actual collection. For ISM Base Tiles and ISM Mountain Tiles it is not, except for the very first row that is generated of the grid

[arctic egret]

how do i get the momentum of the player to follow the camera direction while jumping?

[grim sand]

Set air control in the character movement component to 0.0 for if it is a first person game. That way the player has absolutely no control over their momentum direction whilst in the air

[faint pasture]

with no inputs except aiming?

or holding W and aiming

[gentle quartz]

Does anybody know how I can set my interrupt mode on my set database to search node to do not interrupt only when the idle animation is playing

[faint pasture]

#animation is probably better

[gentle quartz]

gotcha, ill post it there

[ionic skiff]

I need a good system to switch between first and third and fixed cameras

[modest sentinel]

Is there a more elegant way to define the table marked in red as opposed to hardcoding? I tried to connect my "Data Tbl" to it (far left) but got an error:

[uneven crest]

Is there a way to curve a projectile

Like side to side

[uneven crest]

Are you trying to make it so it could be like modular

Like have a variable, and change it but keep the same row info

[sage lagoon]

I'm in the process of creating the battle sequence for an RPG. The earliest form, at least. I'm having trouble getting the program's Turn Sequencer to function. (Image 1)

So far, the program does seem to know when it's the player's turn and when it's an enemy's turn. But then, when I stop a test run, an error appears. (Image 2)

Here is the part of the program that invokes the Turn Sequencer in the following link: https://blueprintue.com/blueprint/j1_pcacu/ It is found under the Game Mode BP for the program.

I have been following a Zevna tutorial on making a mini-RPG but I made a few changes of my own as well. So, if anyone is still not sure on what I'm talking about yet would like to help with the program so far, please send me a DM and I will have a .zip file ready.

[surreal peak]

The GameMode variable you use in that screenshot is invalid. Where are you setting it? Also the UI variable you are casting is already of that type and the cast is redundant.

[sage lagoon]

@surreal peak This is really because I've been trying to get the program to create the widget just so it has the information to work with whenever it is invoked. I was following a tutorial, but I'm not totally sure how it became invalid since it worked before. It might be because I decided to use a separate widget instead of one attached to the player like in the tutorial.

I did it this way so the widget would always be on the screen and from any camera angle.

[surreal peak]

Well it's mostly about the GameMode variable. And you didn't answer where you are setting that variable

[sage lagoon]

@surreal peak I thought I did. Sorry. Anyway, which variable are you talking about? The Turn Sequence one?

[surreal peak]

The GameMode one that is reported as invalid.

[sage lagoon]

After looking at the main BP, I just realized something. I don't think I've properly cast the player BP when I should have after Event BeginPlay.

[surreal peak]

Well this isn't even about the Player BP.

You never set the GameMode variable.

[sage lagoon]

No, so I'll have to cast to that and promote it to a variable.

[surreal peak]

I would also suggest not casting and caching stuff like that on BeginPlay.

It's reasonable to cast and cache something locally before potentially running some loop that would just cast over and over again, but casting and caching on BeginPlay, especially with Object that might not be valid or change later down the line, is not a good idea.

If you need the GameMode to call Turn Sequence on, then just do GetGameMode -> Cast -> TurnSequence in that place.

Also you should get used to adding Parent calls for events/functions that you override.

Rightclick that and click on the "Add Call To Parent" option or whatever it is called

And call that at the start of the BeginPlay node.

Otherwise, you will be fully replacing the code of the parent blueprint's BeginPlay.

[sage lagoon]

Like this?

[surreal peak]

e.g. if you now inherit from the BP that the screenshot is made of, and you add BeginPlay like this, none of the CreateWidget code will be called until you add that parent call.

Yes

[sage lagoon]

So the Parent call is one way to give information whenever anything is being cast to?

[surreal peak]

No. The Parent node calls the code that is in the Parent BP.

This is about overriding events and functions of parent classes.

If you struggle with the concept of Inheritance, casting, overriding functions etc., I would suggest reading up on it.
Blueprints are, in the end, C++ in a very simplistic form. Lots of the same rules apply, so you can't avoid learning those.

[sage lagoon]

Here's what I have now:

[surreal peak]

The "Cast" is only necessary here, because "TurnSequence" is a function that first exists in the BPThirdPersonGameMode and not in the parent classes.
GetGameMode only returns you the GameModeBase parent class, so you gotta cast to BPThridPersonGameMode to be able to call that function.
Casting is just checking the type, since those Pointer variables (called references in BPs to be extra confusing) can point to either nothing (which yours is doing right now) or an instance of the (BP) Class that is either of the same type as the Pointer or a child of it.
Meaning you can have it point to BPThirdPersonGameMode since that is a child or grandchild of GameModeBase. But you also only have access to GameModeBase variables and functions, since the Computer doesn't know that the instance that the variable points to is actually a BPThirdPersonGameMode. The cast then basically check the type and either works or fails, based on what you are trying to do.

[sage lagoon]

Saved your response as an added comment so I don't forget.

[surreal peak]

If it works, you gain access to everything exposed in BPThirdPersonGameMode and above.

I would very highly recommend learning this Inheritance stuff before even continueing with your project.

It's the absolute core of C++/BP programming and if you don't understand why you have to do certain things, you'll cause one bug after another.

[sage lagoon]

Duly noted.

Well, I'm not getting any more errors now. Thanks for the tip!

But I still have much else to fix.

[opal apex]

question: is this a good practice? passing the 'DamageInfo' from the first custom event that triggers a timer by event, into the timer's custom event directly?

[surreal peak]

No, quite the opposite.

That's not a concept even possible in C++. You are just lucky the EventGraph allows it and that pins in nodes are actually holding their state, at least in theory.

[opal apex]

i hoped :( hahhaha

ig i need to make the inputs as local variables after all

[surreal peak]

Try doing that with 2 separate functions. You'll instantly notice that the inputs of function A aren't available in function B.

You need to set the DamageInfo as a variable once before starting the timer and then use the variable in the other event.

C++ would actually allow you to capture the value as a copy for the timer function but blueprints only allow timer events that have no inputs.

[opal apex]

thanks, and yeah i thought so

[surreal peak]

The problem is basically if you start doing that in other cases where the first event is called again before you use the pin.

It would override the pin value.

E.g. if you have a BeginOverlap node and instead of using the OtherActor pointer instantly you use a Delay node with e.g. 1sec. This will work until someone else overlaps before the delay is over. Then the OtherActor will not be what it originally was.

[opal apex]

hmm

[surreal peak]

If you have any kind of function input that you need to use "later" - later being anything that is not within that initial exec pin scope - you should cache them. And you might even need to block the variable from being set again before "later" happened.

[tiny tundra]

I have a Widget on my actor, and I want to affect the class in the Blueprint - 1. to be able to change the class potentially, otherwise at least I'd like to send info to this instance of the class. Can't seem to find a way to do this..

[tiny tundra]

Figured it out. In a nutshell I just did this. Create Widget, then push the class I want into here, and then assign that as a widget component variable to be able to change the properties.

[surreal peak]

In theory you should be able to just get the user widget from the component directly.

And if you would want to change the class on it you should be able to do that via a set widget class call on the component, which should internally respawn the widget.

[tiny tundra]

"in theory" yeah, you''d think so, but after banging my head against the wall for longer than I'd care to admit, there didn't seem to be a way to do that (via blueprints, anyway). Which is fine, this works well enough for my purposes and doesn't seem to add any extra work-overhead either way. It just wasn't very intuitive to figure out, fortunately I found a blog post where someone mentioned this method.

[surreal peak]

Well plugins would be c++

Blueprints are def not capable of doing what you wanna do here

At least in the sense of properly including stuff

[spark steppe]

i'm pretty sure that it works in BP Oo

there's at least the GetWidget() node to get the widget instance from the component

[tiny tundra]

Well it is definitely working (with the BP method), fwiw. As far as editing properties & swapping out the class, tested them both.

[crude glacier]

Any idea why my accelrtation script doesnt work, if i connect scale value to a constant value it works fine

[surreal peak]

Is that a Character or a Pawn?

[crude glacier]

pawn

[surreal peak]

AddMovementInput is usually not meant to be used like that.
ScaleValue is supposed to be something around 0 to 1. Potentially higher or lower, depends on the usecases.
The underlying movement system/component usually takes that MovementInput and multiplies Acceleration into it and then uses DeltaSeconds to update the Velocity.

If you still want to use it like that, then I would suggest removing the GetWorldDeltaSeconds part.

[crude glacier]

ahhh ok thanks very much

[sharp ferry]

is it possible to place another BP actor as spawn in a differnt spawn point and level?

[lofty rapids]

you want to spawn it into another level ?

if your using streaming perhaps

[sharp ferry]

YES

yes*

[lofty rapids]

are you streaming ?

[sharp ferry]

i want to spawn in a differnt level a differnt BP character

no why?

wym streaming?

[lofty rapids]

when you say spawn in a different level ?

you want when you goto that level it spawns ?

because i don't think you can just spawn into a level if your not streaming

[sharp ferry]

i just want to spawn a differnt character on a differnt starter point

and control it

in another level

[lofty rapids]

ok so i would just change the game mode

create a new game mode, set it as the level override

and set the default pawn class to the new player

in the override

and use player start

player start will be where the char loads in

basically when that level loads, it will load that game mode, load and possess the default pawn, and place the pawn at player start

if you want this point to be dynamic

you may want to look into the GI for storing the point

[sharp ferry]

because what i have to do is change the clothing of my character but im gonna change also her anims idle and walk so i need her as a new BP

[lofty rapids]

sure you can do this np

like i mentioned with the override

[sharp ferry]

but i also need to do that when she press E near the door, she teleport and spawn that new BP character

[lofty rapids]

does the door take you to the next level ?

i'm not understanding what your saying about this door and teleport

you can spawn the character at any point

but if you want to use it in the next level, i suggested what to do

i would use a parent class for your character

and have the children be different ones

so you can keep common stuff and not have to copy it every time

[sharp ferry]

yes

[lofty rapids]

or use the player controller actually as well

for your inputs

to not make the parent to heavy

[sharp ferry]

i want to do that when my BP 1 character interact with the door, it telport and spawn a differnt BP character (its her with differnt anims idle and clothing) in the new level

[lofty rapids]

so then do what i said, but when you interact with the door, just open the next level

should be good to go

[sharp ferry]

it seems hard as hell

[lofty rapids]

did you create the character ? @sharp ferry

[lofty rapids]

first thing i would do is setup the second level so when you open the level, your using the new character and where you want to be

then open the level with spacebar, or E or something that your not using

if that is working

then just open the level when you open the door

[inland walrus]

Anyone know why it is destroying room1's when I try change room2's?

[sharp ferry]

once i get to UE i will re read all ur infos and try to figure it out

[lofty rapids]

i can't read any of those images

[inland walrus]

my b it's an ultra wide, I'll post them on bp paste

[inland walrus]

https://blueprintue.com/blueprint/cnhd3k_p/

It's gotta be to do with the updater

thats where its destroying

[lofty rapids]

so what is guild room target ?

on updater, where you destroy actor, this is the problem its destroying the wrong one ?

you create something with new var

but if you create another one, you set the same var

i'm looking at the code, i'm still a bit confused about it lol

[inland walrus]

oh so guild room target needs changing to new var?

[lofty rapids]

is this intended to spawn the two of them when you run update ?

or it's intended to spawn one

[inland walrus]

Basically what should happen it shouldn't affect other rooms, for e.g. if I put a training room as room01, then change room02 to a storage or something, it deletes room01s

[inland walrus]

This video here shows it

[lofty rapids]

i think because new var was the created room right ? so when you destroy newvar your destroying the last room you created

is this code on each actor ? or like a manager ?

[inland walrus]

Yeah pretty much, but I thought a set on room name would change which is being targeted

& There is no manager, this is all their is, it works fine with just one but not multiple

[lofty rapids]

as far as this is all there is, this is on each seperately ?

[inland walrus]

Sorry I dont follow

[lofty rapids]

what bp is this code on ? you have three actors, or this is one actor ?

[inland walrus]

just one actor component which is on the player

[half field]

Need a little help here. So i have an item system set up, where equipping an item creates an actor, attaches it to the player's hand socket, and plays the corresponding montage for the player holding the item. The problem? For some reason, it bugs out, and while visually the right arm does play the montage, the actual bone transformation remains the same, like it's still using the idle/walk animation. This causes the item to appear where the hand would normally be if you don't have an item. If you walk/run around, the item follows where the right hand would be during those animations. Any ideas?
And going to the animation itself with a preview mesh added to the right hand socket, it does display it correctly, so this might be an issue with how blending animations works, but i just cannot figure out how to solve it. Also, attaching it to the hand also doesn't work, since it seems like it's not just sockets, but the entire right arm that is affected by the montage still thinks it's in the idle/walk/run animation, and only visually changes .

[lofty rapids]

so guild room target is the one of the three your using ?

i see so you spawn in there

[inland walrus]

yeah

[lofty rapids]

and since this is the actor component, on your character

it deletes the last one

which is in the first bin

you may want to store these vars on the guild room targets themselves

so that each one has it's own to add/remove

- new var
+ guild room target -> new var

altho i would call it something other then new var tbh, try to make variables as descriptive as you can imo

but this way when you go to do the check your checking against the current one your interacting with

so it will remove that, and not just the last one you interacted with which could be in either room

[lofty rapids]

#animation ?

[half field]

honestly i'm not sure if it's caused by the montage itself or the animation blueprint, that's why i also posted it here

[inland walrus]

Alright I'll try that , thank you, I'll let you know the progress

[inland walrus]

I've done that but it's not not destroying any

[lofty rapids]

well i see your still using new var on the == check

[inland walrus]

ah yea

[inland walrus]

top g

thank you

[inland walrus]

Quick one, if I wanted to remove only 1 from my map, how would I do it?

[lofty rapids]

you want to remove a specific one ?

[inland walrus]

So lets say the map is like this:

Class / Interger
Training room: 0
Storage: 2

and I want to remove 1 storage room, how would I set that storage to 1

[lofty rapids]

i'mnot sure i'm following

you have a map with two key/value pairs ?

class key, integer value

[inland walrus]

Yeah

[lofty rapids]

and you want to remove one

then select the class

[inland walrus]

I want to remove a value

interger

[lofty rapids]

ok you want to change one of the integers

[inland walrus]

yeah

[lofty rapids]

change it to a different value ?

[inland walrus]

exactly, I'd like to find which one the user is wanting to remove, i.e. storage -1

[dark drum]

Readd the entry but with the new number, it'll override the value.

[inland walrus]

This is what I was thinking

I'm not sure how to set the new value

[lofty rapids]

so i don't think you need this loop

just do add

and pick the key

and set the value

it will overwrite it

[inland walrus]

ohh, I see

[dark drum]

Also, be careful with the 'Get Key Value by Index' as maps are unordered so when you add a new entry, there's no guarantee the order will be the same.

[inland walrus]

I thought Add would just do this:

Storage: 0
Storage: 0 rather than change Storage: 2

[inland walrus]

Got you

So the 1 is the amount to add? I thought it was the entry ID

Even then there isn't a subtract node

[lofty rapids]

if you want to subtract one

then find

it first

then subtract, then add it

[inland walrus]

So it's like this?

[lofty rapids]

yes

[inland walrus]

You'd think they'd just have a subtract node xD

Thanks though I'll try it out

[lofty rapids]

what with the room to integer ?

you may want a struct, for more information per room

[inland walrus]

Yeah I've been thinking of moving over to a struct, I'm going to try continue how I am and if it get's to a point where I'd rather struct I'll switch over

but so far it's doing everything I need it

[lofty rapids]

makes sense

[lofty rapids]

yes, most things in bp are a copy, if it were a reference you could do something like --

[inland walrus]

I think the add is setting it to 1 rather than adding 1

[sharp ferry]

im trying now to add it as new character to spawn

[lofty rapids]

yes it is, it's adding a key/value pair, not add to the current one, you need to find then add, then "set" using add

same as with the other where had to find it first

[inland walrus]

Got you

[lofty rapids]

find gets the current value, the add node will "overwrite"

because maps have unique keys

so when you "add" with the same key, it overwrites the value

[inland walrus]

Got you

Thanks man

[lofty rapids]

well wouldn't you use the passed class in the find as well ? and pass the guildroom target -> class when you call it ?

you could do that, or hardcode it like the bottom one, but the mixed thing on the top one is odd

but one thing is to be consistent in how you do it

[charred girder]

is there a node or setting that makes a socket not have influence over anything? just for cosmetics, i have a sword that gets attached to a hand socket and it works, but i want to add my other hand to the sword to two hand it but dont want it affecting anything

im using the vr template

[inland walrus]

Yeah I know what you're saying and I could do it exactly like the bottom

[crude glacier]

Are there any good resources to make any auto spline pcg that keeps make spline forward

[polar barn]

How do i make it when the Score reaches 1 it spawns an actor BP
I have it where I gain 1 score when my AI is destroyed
I just don't know how to make it when the score = 1 a Actor BP is spawned

[sand shore]

Instead of directly modifying the score variable, you can make a function like "Increase Score" or "Change Score" that you'd call instead of incrementing or whatever you're currently doing.

That function could spawn the actor if the score was lower than 1 and will now be higher than 1.

It might be a good idea to avoid spawning actors directly within that function, because the function needs to reference every actor it spawns, so that means those actors would always be loaded. You can separate things out with event dispatchers - you might have an event dispatcher that includes the Old Score and New Score, or you could just broadcast that the score has increased with only the new score. Lots of stuff you can do there.

[polar barn]

ok thanks ill try it later today or tomorrow

[peak trail]

I use a blueprint to spawn an actor with a mesh when i click the mouse
When the actor is spawned my WASD movement is disabled
If i delete the actor then i can move again.
Why is this happening?

[lofty rapids]

this sounds really odd, if you don't spawn the thing the print string fires off, but if you disconnect the execution to the spawn, your wasd still work ?

[peak trail]

fixed it. was a collider issue

thanks

[hardy merlin]

If I use the Set Game Paused node, how can I unpause after N seconds elapse? Seems like all ticks and timers stop.

[lofty rapids]

you can tick while paused

[crude glacier]

can anyone give advice on how to make a loop adding a spline point forward every second, the thing i need help with is to get the location to put it in and stuff

[lofty rapids]

get transform on spline by distance

[crude glacier]

ok thanks

[hardy merlin]

Is that a setting?

[lofty rapids]

yes
https://www.youtube.com/watch?v=rsVTM8_sMzg

[lofty rapids]

so basically you move along the spline increasing the distance

if you need to loop around set it back to zero when you reach the length

[crude glacier]

yes thanks

[tired tartan]

I need help, the blueprint function keep telling me it needs physics to add force eventhough the object I'm trying to add force to has simulating physics turned on

[lofty rapids]

so your adding force but it's not applying ?

where does it "keep telling" you ?

[tired tartan]

well, Im using a function from a blueprint function library that simulates physics on a object, but when it tried to add a force to it, it throws me an error that says I need physics enabled on that object, also they both on a sequence node

[crude glacier]

what am I doing wrong, Im tryna make it so every second a spline is added

[lofty rapids]

wdym "every second a spline is added" ?

[crude glacier]

so theres a for loop and a point is added to a spline making it longer and so on

[lofty rapids]

and your sure it has physics enabled ? is it an actors component ?

[tired tartan]

its an primitive component

[lofty rapids]

so you have a for loop, or this is supposed to add points to a spline ?

[crude glacier]

omd i forgot to add it

ive been on ue5 too long

[crude glacier]

I dont know what im doing

[lofty rapids]

i can see that lol

i'm kind of confused at what your trying to do tbh

so i initially thought you wanted to move along a spline

but you want to add stuff to it ?

dynamically in a loop ?

[crude glacier]

Im trying to make a loop, that gets position of the last point and adds another point and repeats

[lofty rapids]

so the idea is that either way it's set to simulate physics ? if is simulating then you go do some stuff, if it isn't then you set it to simulating. btw i can't really see much with that spaghetti

[lofty rapids]

this is how you get the last points location

[crude glacier]

ooh thank you very much for your time

your a goat

[lofty rapids]

then you can add a spline at the end

in that location, but you'll need a forward or something

or some offset, like y - offset or something

[tired tartan]

I have a branch that will do nothing if it isn't simulating physics, but when I disable that and run it, it gets me this

[lofty rapids]

i mean you code shows that you check if it is simulating physics and if it's not, then set it to simulate physics,

[lofty rapids]

and your sure that has simulate physics checked in details ?

[tired tartan]

yes

but, it's still not applying any force

[lofty rapids]

looks like kircorner, and kitfloor

these are components of singlefloorHouse ?

[tired tartan]

yes, the meshes are parented to a simple scene component

[lofty rapids]

can you try the node set simulat physics to true and see if it works ?

[tired tartan]

its not a physics object btw

I used to have it added to every mesh, but it was taking too much resources and tanks performance, so I have as the parent of the meshes

[lofty rapids]

so you have simulate physics on the parent ?

idk what you mean by this ?

[lofty rapids]

are you saying simulating physics on all the meshes was too much ?

what are you doing that you can't shut it off ?

as far as turn it on, then turn it off later

[tired tartan]

no, its that having to add a scene component that tells how close to the object it needs to be in order to simulate phyiscs
and needing to add it to every mesh is too time consuming, so I made a blueprint function that does that, but having it all fire at once especially if I want hundreds of houses would destroy the game's peformance, so I instead put the meshes to the scene component makes it so much easier, less peformance issue, and less time consuming but now I im having trouble trying to make it work

[lofty rapids]

i'm still confused, but you need simulate physics on

in order to add force

[tired tartan]

a house that has dozens of meshes and pieces

[lofty rapids]

and they all simulate physics ?

[trim matrix]

I need a job💔

[tired tartan]

well, the thing is, it only simulates physics when its close to an certain object

I think I should make a blueprint component that has a static mesh along with some number variables and a bool variable

[lofty rapids]

and it's close but isn't simulating ?

[tired tartan]

yes

even though its simulating

[lofty rapids]

it's not simulating most likely

the code is most likely logically not setting it to simulate physics

unless it's a bug in unreal

[tired tartan]

its still tells me that I need to give it physics inorder to add force, even though the physics is enabled

[sage lagoon]

I would like to post this forum link. Any help is greatly appreciated: https://forums.unrealengine.com/t/when-is-it-my-turn-rpg-turn-order-question/2599980

[tired tartan]

unless I have to make a c++ component that renders a static mesh that includes some variables in it

[lofty rapids]

so you have a turn, which sets the player turn, i would then see who's turn it is and show if it's the current player, like if your player 1, and it's player 1 s turn, then it should show ?

[lofty rapids]

idk how you can avoid simulating physics if you want to add force

the chances are high that the function isn't working correctly and not setting the physics to simulate on

[tired tartan]

also how can I create a component that is similar to the static mesh component, but has a few variables such as float variables (for like health of the object), and bool variable (that can say if it's alive)

plus I cant make it as a actor

because I need to use child actors which can be problematic

[lofty rapids]

you could store a map of mesh to struct @tired tartan

then just find your mesh, and get your settings

on the actual house that contains them all

[sage lagoon]

Not only that, but when it's a party member's turn the widget with the buttons should appear. When it's an enemy's turn, the widget should stay collapsed.

That's what I want it to do, anyway.

[lofty rapids]

ok, so you need to know what members are in your party ?

the way i do turn based is a ready system, when all players are ready, it switches to the next player

[sage lagoon]

No, I just need to know how I can control when the commands appear and when they don't.

[lofty rapids]

when, or how ?

because the how is pretty easy

you need a reference to the widget

[lofty rapids]

on player change, check if it's in your party

if so show the widget, if not hide it

[sage lagoon]

So, what nodes would I need to set and where?

[lofty rapids]

what is the widget name ?

the class name

show where you create the widget and add it to viewport

i'm assuming you do it on begin play or something ?

[lofty rapids]

do you have any way of determining who's in your party yet ?

i see your organizing the characters by speed

[sage lagoon]

Yep, and the turn counter too, as shown in the forum link.

[lofty rapids]

it looks you may want to use "begin turn"

your calling this on the actual character ?

i'm guessing it's a parent function or event

[lofty rapids]

what about the widget

[lofty rapids]

^

the one you want to hide/show

[sage lagoon]

This is under the CharacterBase BP.

And on this link is the code of a status widget which calls the button one.

https://blueprintue.com/blueprint/tr9ionbj/

[lofty rapids]

i see you have the persons turn at the top right, is this correct ? and can you use the same event ?

[sage lagoon]

The top-right shows whose turn it is and the left shows the statistics of the specified character.

Those are part of the BattleStatus widget, which initializes the BattleUI one.

[lofty rapids]

so the battle ui is what you want to show hide ?

this is the buttons that you have ?

[sage lagoon]

Yes. That's the one with the buttons.

[lofty rapids]

ok so character base is the parent class, and you call begin turn when it's a persons turn

this is a parent function ?

[tired tartan]

Uhh

[sage lagoon]

Yes, the CharacterBase BP is a parent one, as it sets the parameters for party members and for enemies, as well as behaviors.

[lofty rapids]

well when you call begin turn

thats when you want to check for who's turn is it

check if it's in your party

but do you have a way to differentiate party members from other ?

[sage lagoon]

I only have one for the time being, and for the demo too. There will be up for four in the future retail version, though.

[lofty rapids]

https://www.youtube.com/watch?v=cf25ekO-AFs

[lofty rapids]

well i would put a boolean on the parent

partyMember

and set it on the children that in your party

then on begin turn

check if you or a party member is playing

[sage lagoon]

Huh...I think I know what you're getting at. So I just declare the Boolean variable and then assign it to the player character BP?

[lofty rapids]

assign it in the children

if they are partyMembers

then it will be true

[sage lagoon]

Like, call the parent function and Boolean in the child - in this case, the player character BP who will also be a party member.

[lofty rapids]

if they are not then it will be false

then you can get the current player, check it's boolean

[lofty rapids]

your already calling the parent function begin turn

get self, and check the boolean

this will be the childs boolean value

does that make sense

get current player from characters array

check if the boolean is set

and i would set it to true on the original player as well

just for less code

you can just check for partymember instead of current player as well

[sage lagoon]

So here's what I have, under the CharacterBase (Image 1).

And here is the BP under the ThirdPersonCharacter whenever the Attack button is clicked (Image 2).

Oops, that Set PlayerTurn should be unchecked.

Set to unchecked, I mean.

And sorry, I was going over the BPs to set up what I just showed you.

[lofty rapids]

np, np

it doesn't make sense what i wrote tho ?

you can show and hide it in the same function

[sage lagoon]

Kind of. Do you have any examples?

[lofty rapids]

do you know how a parent variable works on children ?

you can set a parent variable

and when you get and cast, the variable will be the child value

so each one can have a partyMember boolean

but it's set on each child

[sage lagoon]

Oh! The casting wasn't even needed!

Since the ThirdPlayerCharacterBP is a child to the CharacterBase.

[lofty rapids]

so is this something else your doing ?

what is player turn boolean about ?

[sage lagoon]

I'm trying to set up the first form of a battle sequence, from a tutorial on Zenva.

https://academy.zenva.com/course/unreal-turn-based-rpg-course/

[lofty rapids]

your key would be the static mesh class, your value would be a struct with settings, do you know what a struct is ?

[sage lagoon]

But I made some changes to that, such as having a separate widget instead of attaching one to the player character.

[tired tartan]

Oh, I forgot that I can make a blueprint based on actors and other things

[lofty rapids]

i would just keep a map variable in each house actor

[lofty rapids]

i mean what i said is the solution, you can scroll and read maybe look some stuff up

you also need the widget reference

so you can turn it on and off

but basically set that variable on the partymembers, then check for it in begin turn

where ? in begin turn

check: self -> isPartyMember

if true show widget

if false hide widget

[lofty rapids]

you can make a manager actor that holds variables and does things

[fervent jolt]

Hello. I was wondering, when using the select node, does it only run the code to get the selected value? or does it get every value then return the selected one? because in this code GetLeftPath is an expensive function, and I wouldn't want to call it if not needed.

[lofty rapids]

yep, it gets both

i'm fairly positive about that

[fervent jolt]

darn, thank you very much for the quick response

[lofty rapids]

"evaluates all of its input pins before choosing an output based on the provided index." -google

[austere orchid]

Error I've never seen before when compiling a bp
COMPILER ERROR: failed building connection with 'Replace existing input connections' at On Focus End
Do interfaces work differently on actor comps or something?

oh, it seems like i cant plug both an actor + actor comp in to the target

[lofty rapids]

thats your problem most likely it won't know which one to use

[sage lagoon]

Usually, you don't want to use Self for something like that. Try one of the "Get Player" options.

Or, if you haven't already, cast to that BP and promote it to a variable. Then, use that variable and attach it to your On Focus End.

[modest sentinel]

Yeah more modular and streamlined. I already defined the table on the far left, I don't want to have to manually select it again in my Get Data Table node

[trim matrix]

hi ive made this room manager bp for my game where you can vacuum up items like chibi robo, the items you vacuum are working fine but im now trying to make trigger boxes that are like the bounds of each area. like for example if theres a house level, each room would have its own manager bp to keep track of how many item bps are inside the box. rn i have it printing how many are inside the box. but im not sure how id fix it so that i can have multiple room managers and keep their counts seperated

[olive yarrow]

I'm redoing my actor used for drawing splines for my RTS mode - I have a spline and the camera attached to it but i'm at a loss on how to smoothly move my camera along the spline as i scroll wheel.

I'm familiar with splines enough to move AI around them but for whatever reason this seemingly simpler task is... not.. simple? Anyone got a tutorial layin' around?

I have this, i think i'm within the right path

okay this seems to be pretty close, but the location doesn't really move much

here's the spline

[trim matrix]

i got it to sorta work with using last index but now when the player collects an item, the count decreases by 2 instead of one even tho only one object being sucked up (ik the number being 9 is wrong too but its bc i have the array instance editable and its still set to the 9 i had in there previously but i wanted to just use 2 for testing rq but ill be fixing it)

also for some reason after the trace runs once, it randomly runs again like in this clip i only pressed the input once then only the wasd keys and it still kept going off

[scenic crypt]

I dont know if I am just doing this wrong or what. I am just trying to make my clock show as double digit numbers. But the format text wont allow me to. Does anyone know how to fix this / get around it? Fairly nooby with blueprints

[graceful sage]

Second one looks messed up?

[surreal peak]

Can the FormatText even do that? You'd want to call "ToText" on the Integer and set it to min 2 digits in the ToText node.

@scenic crypt

And then connect the resulting text with the FormatText node.

Unless the FormatText node should support this already. Don't think I've ever done it with that.

[scenic crypt]

That worked. unfortunately I have been learning with AI, and it tends to... Have some bad advice sometimes.

[surreal peak]

Yeah, wouldn't suggest learning from AI. Even YouTube tutorials that are potentially outdated or spreading some false info are better than that.

[desert briar]

When I eject from my player character in PIE, I still see the UI. Can I get a "clean" view?

I can open the widget reflector tool, hover over my UI and set opacity to 0

which is a 0/10 in terms of workflow

[drowsy roost]

I love your profile picture

[lofty rapids]

are you trying to move from one point to another, or just a certain distance down the spline ?

[surreal peak]

Ejecting wouldn't remove your UI. I can quickly check what the Console Command for the UI part is.

[lofty rapids]

because 100 is such a small distance you probably hardly notice

[lofty rapids]

what does on vacuumed look like

[surreal peak]

Hm, I can't for the life of me find this. I'm sure there was something. I will need to look a bit longer.

[desert briar]

there is one? i did spend some time looking for it, couldnt find it... i did find forum answers from you though, from 2014!!!!!! you've been around for a while 🙂

[surreal peak]

Yeah, I can't find it either. I went through the FEngineLoop::Tick now, up until the Renderer and there is nothing to prevent the drawing.
I could have sworn there was a console variable that can turn drawing off for Slate.

And yeah, I found that post a few minutes ago too. I did also post a lot of crap in 2014, since that was where I started learning.

I basically learned by answering everything I could find, especially on the old AnswerHub.
I spoonfed people answers by learning how to do the stuff they wanted myself. Can't recommened that but it did its job.

In theory, you can hide it if you get your hands on the Viewport Slate Widget.

But I assume you have no C++ knowledge.

[lofty rapids]

i would just make a button that hides the ui

like click e, hide/show ui

[surreal peak]

Yeah, in most cases your own UI is already set up with a very limited amount of root widgets.

So widgets you, yourself, called AddToViewport on.

And anything else is either added to those via the designer or runtime.

But in the case that you have a very messy UI setup, I can see that adding such a button later down the line can be tricky.

[lofty rapids]

ya if you need all the widgets, hopefully you have them in the HUD

i would make an array

[surreal peak]

AddToViewport calls will ultimately do this:

    else
    {
        // We add 10 to the zorder when adding to the viewport to avoid 
        // displaying below any built-in controls, like the virtual joysticks on mobile builds.
        ViewportClient->AddViewportWidgetContent(FullScreenCanvas.ToSharedRef(), Slot.ZOrder + 10);
    }

At least if you don't add to PlayerScreen.

Which in the end just adds the Widgets to the ViewportOverlayWidget:

void UGameViewportClient::AddViewportWidgetContent( TSharedRef<SWidget> ViewportContent, const int32 ZOrder )
{
    TSharedPtr< SOverlay > PinnedViewportOverlayWidget( ViewportOverlayWidget.Pin() );
    if( ensure( PinnedViewportOverlayWidget.IsValid() ) )
    {
        PinnedViewportOverlayWidget->AddSlot( ZOrder )
            [
                ViewportContent
            ];
    }
}

I don't think that thing is protected or public though.

Ya, would need to test that, but there is an angle of just hiding the SViewport.

TSharedPtr<SViewport> GameViewport = FSlateApplication::Get().GetGameViewport();
if (GameViewport.IsValid())
{
    GameViewport->SetVisibility(EVisibility::Collapsed);
}

But yeah, C++. Guess no BP console command stuff.

[dark drum]

'Slate.GameLayer.ViewportSlotVisible false' would hide the viewport. You just need to remember to set it back to true when you've done as it'll persist.

[inland walrus]

Anyone know why my timer only connects to the hud if I do the wire at the end of the video?

[dark drum]

I would use 'SetTimerByEvent' instead of by function name. Helps prevent mistypes in the function name and handles function renames. (usually)

[inland walrus]

I've tried that but still got the same issue with the hud reference

[dark drum]

As for why it's not working, its most likely that a player controller doesn't exist at the time its first created meaning the cast fails.

[inland walrus]

I see

[dark drum]

Personally, i would just have an event dispatcher on the time manager thing you have and call it when ever the time is updated. The UI just binds to it and knows it needs to do its thing.

[surreal peak]

Aha, there was one after all. Nice!

[lofty rapids]

did you try a longer delay then 0.2 to see if works ?

[dark drum]

Yea sometimes things are hidden away. 😅

[desert briar]

huge improvement, thank you! it also works with the player canvas via Slate.GameLayer.PlayerCanvasVisible 0

[inland walrus]

yeah I just tried 2 seconds and still errors, The only work around I can think of is if I set it each time in the update ui event

[dark drum]

Same, either there's already an answer or you have little project of exploration. 😅

[inland walrus]

I've fixed it, instead of doing event begin play > create widget in the player controller I cahnged event begin play to event on possess

[wicked cairn]

Anyone got tips or suggestions about how to go about getting ai to climb walls to get to another destination on the nav mesh without using nav links?? Ex. My thinking is that they just start climbing the wall if they’re next to one by tracing for a ‘climbable’ trace channel towards the direction of their goal

I basically don’t want to have to place tens of nav links everywhere they can climb

[dark drum]

Is there a reason you don't want to use nav links? Its what tells the AI they can get from A to B even though its not on the nav mesh.

Also what version of UE are you using? In 5.6 I believe there's an auto nav link option that auto generates nav links.

[wicked cairn]

Wouldn’t I have to place nav links all across a wall if I wanted them to attempt to traverse it but not in the same one spot if it’s just one nav link?:0

I’m using 5.5.4

[dark drum]

Ahh, yea no auto option then. Unfortunately without nav links the AI wouldn't know it can get from A to B when it leaves the nav mesh. You can add nav links to BP's so if you have wall pieces, you could create a template for them with the nav links pre placed.

[wicked cairn]

Ahhh damn okay

Thank you for letting me know!

[cunning zodiac]

Hi all! I'm new to blueprints and am trying to hammer out an issue. I'm recreating a drone camera using a plugin and for some reason my WASD movements arent working. The enhanced inputs are working with the mouse movements. The WASD seems to be pulling from the plugin itself, and the input mapping context and actions are in the details Input section. I imagine I'm probably missing a checkbox or something somewhere. Or I'm misunderstanding what I'm looking at. Anyone have any thoughts?

[lofty rapids]

unfortunately it's a plugin

so maybe they have a discord ?

or some sort of contact

[cunning zodiac]

Okay, I'll see if I can hunt it down. Thank you

[crude glacier]

what am I doing wrong, I just want to test if a spline point is added, sorry for it bieng 3rd time

[lofty rapids]

wdym test if it's added ? it should be added, if you want to test a location use get location at spline point

[crude glacier]

so I add my spline into workspace, when i run it isnt added?

[lofty rapids]

what does the spline look like ?

it should be added

do you get any errors ?

[lofty rapids]

your trying to add a space to the end of a spline ?

[crude glacier]

ye

or any

I need to test it

construction

[inland walrus]

I know my issue with this is metahuman related but I dont seem to be able to solve it there for days now and I wonder if anyone else has/or solved this issue unrelated to metahumans as it's an issue with accepting the EULA.

[lofty rapids]

set both to world

you got one local, and one world

[crude glacier]

still nothing changed

[crude glacier]

it looks the same when i run

[lofty rapids]

this will add it to the end

change the x instead of y

[crude glacier]

ok Ill test

what variable is that?

[lofty rapids]

its an integer

...

[crude glacier]

ok thanks alot for help

[zinc flicker]

I got a small question about Object Pooling, i currently follow some tutorials, most of them use the approach of Bullets Pooling and use Actor Pool.
If i want to pool enemy's would i make my Pooled Manager a "character"? Since some tutorials make the Bullets a child of the Actor and i cant make a character a child of an Actor without bricking everything.

[waxen ice]

Nah, your manager stays an actor, but the objects you are pooling there are of the different class.

[lofty rapids]

the bullets a child of the manager ? or am i misunderstanding because that doesn't sound right

[zinc flicker]

https://www.youtube.com/watch?v=f797l7YTcgc
I followed first that tutorial but i am not sure it requires to make the pooled object a child of the actor so it only works for actors thats what confused me.

I tryed this tutorial https://youtu.be/lpF6HEqr9XI this one worked instant out of the box.

[lofty rapids]

well what he does it make a parent, so that you can pool multiple classes

[zinc flicker]

The only problem i have currently is that if i set the pool to 10 and i spawn all 10 objects and i want to spawn new ones it just puts out an error.

From the first tutorial i copied an "time to live" code to kill the object after some seconds.

This in theory works but isnt there a way to just remove the first spawned actor and put it back into the Pool without putting it on a Timer?

[lofty rapids]

these are bullets ?

[zinc flicker]

For now i just tested out for "Coins" that drop after you kill a monster

[lofty rapids]

you should put them back in the pool when they hit something or reach a certain distance

[zinc flicker]

I first do some coins that drop after kill of a monster to understand the system first before i start applying it to other stuff like footprints or enemys

[lofty rapids]

if your pool length is zero i would just spawn some more

tbh

[zinc flicker]

Yes in his case its bullets that hit a wall but if i want to have coins on the floor they dont really despawn if they are not picked up

[lofty rapids]

^ this will increase your pool to whatever size

you want the pool size to be about the max coins that can spawn at once

[zinc flicker]

On "Object to Spawn" i have set it for now to 10 just to test the stuff so with "Pool Lenght" it would just add more like make 10 to a pool of 15?

[lofty rapids]

if you remove index and there are zero left, maybe add some more

and what begin playis this ?

[lofty rapids]

make your pool size just initially big enough is probably the idea if your going to use a pool

but you can keep increasing it

just in case

[lofty rapids]

i see you remove index, this is going to deplete your pool

[zinc flicker]

You mean something like this where the ObjectToSpawn the "10" adjust depends if you have enough

So if i want to spawn 1 more it changes it to 11

And if i deactivate it it takes 1 away.

[zinc flicker]

Yeah in theory i can just do spawn 200 but i was just wondering what happen if there is 200 in the world, i guess the first tutorial video just makes it into a TIMER so after 10 sec or so it disapears, and the 2nd video destroys it after hitting a wall.

I guess i could put it on a timer when the player is to far away a 10 sec timer starts and puts it back into the pool

[lofty rapids]

basically when they are in the pool you shut them off

no tick, no collision

stuff like that

then when you take them out, you can turn that stuff on

[zinc flicker]

Yes i did that basicaly i turned off Tick / niagara / light everything

[zinc flicker]

So in theoryi could just slap 1000 on it since its hidden it should not eat performance?

Ok i have hard 120FPS when i spawn 1000 hiden objects it goes to 105FPS

[lofty rapids]

yes 1000 is a lot

blueprints doesn't handle this very well

[zinc flicker]

Ok the performance in standalone and viewport are like worlds apart i got like 400 FPS and with 1000 pooling still around 400FPS

[lofty rapids]

right, standalone is more performant for sure

[zinc flicker]

Standalone is similar to a real exported game more or less? (packaged project)

Can i use the same Pool for enemys too that i use for coins or should i rather make new Manager or new "object to spawn" for my enemys?

I mean i could spawn like 200 Coins and 200 Monster just seperate i not sure whats cleaner

I try to make it a "BP_MasterEnemy so i can just swap out mesh / hp to use the same pool for enemys.

But i am not sure i can mix and match coins + enemys

[lofty rapids]

arrays you can only store of one type

so they would have to share a parent

and you would end up casting or something to tell the difference

[zinc flicker]

So i better just make 2nd Manager to keep it clean

[lofty rapids]

since they are all actors you can use just actor

but now you have to determine the difference

before you take out and destroy

so it would be less efficient imo

[lofty rapids]

you could make a functionality in the manager that you set the class name, and then from there it creates the pool

and spawn the class type

if you spawn actor of class you get an actor back

but you can pass an array, and a class type to a function

might be usefull if you want to expand it

[zinc flicker]

BP_ObjectPoolManager i can keep using but i would just use what iset into the image but for enemys

EnemyToSpawn
EnemyPool
EnemyLastIndex

And on event Beginplay i make a "Sequence" with Spawning 200 Coins and 200 Enemys

[lofty rapids]

in reality you'll need another manager anyway for the movement is going to be different and how they work will be different

[zinc flicker]

Basically the Idea was to have similiar swarm mode like Vampire Survivers as an example and i would use Destroy/Spawn but i read, if i want to have 200-300 enemys on screen a pool would be more performant.

[lofty rapids]

yes it will

because your not destorying/spawning them

which is overhead

[zinc flicker]

Yeah the bigger problem is anyway how to get performance since i think after around 1000 monster on screen i dip into the 30 FPS anyway.

I feel like all this Survivor games just use "images" to save on performance.

I even started to remove the shadow of the monsters and replaced it with a Circle Decal below it to fake some shadow.

And i turned all tick off that i don't need.

Because before i dedicate to much time i need to figure out if the main part of the game even works.

[lofty rapids]

1000 on screen at once is a lot

[spark steppe]

profile it and optimize

i guess character movement and animation take up all your gametime

[zinc flicker]

I already simplified it a lot

Basically the Enemy autowalk forward and just change animation on attack and go back to walk

I tried out to make Enemys just actors but they cant move properly.

I tried to do Pawns but in pawns i can use them just as drones the problem is they dont respect collision and basically merge all into each other.

Then i just went with characters and tried to remove all tick that doesn't destroy the function of the enemy.

I tryed to find a middleground but i really feel like the Movement Component etc probably uses a lot of performance

I use stylized figures so they not like AAA ultra qualty and i changed the textures from 2k to 265 since they far away anyway. But 1 enemy in memory is like 200 kb with blueprint and textures so i think i reduced that far down.

The bigger problem is that when monsters die they should drop some coins so there is always an "object" in the world.

I tried to make the coin a niagara effect this way its more performant.

[waxen ice]

Hi guys!
Is there a way to disable/enable all currently active Input Mapping Contexts?

I have DefaultMappingContext added at BeginPlay in Player and in InventoryComponent (which is added to the Player) at BeginPlay I'm adding to the PlayerController InventoryMappingContext. But when I call DisableInput node it seems to disable only inputs from DefaultMappingContext.

[crude glacier]

anyone know how to add a one second delay before adding spline point, I tried putting delay and set timer event before add spline point but it didnt change it , the same striaght after construction script, should I make my own timer or is there a good ndoe for it?

[languid pagoda]

Hello Everyone, could use some help if anyone is available. I'm trying to set up a "stop time" mechanic in my game. I used almost identical logic for slow time and it works, but stop time is proving difficult. I want my PlayerPawn to be able to move freely while time is stopped. I have this within my CustomPlayerController logic and this in my actual pawn to override the time stop. I also have "tick even when paused" as true for all components.

[lofty rapids]

you have two of the same event ?

[languid pagoda]

kind of, one pauses time and the other is giving my pawn custom time dilation

[crude glacier]

i think its sm with red input

[languid pagoda]

but both triggered by the same IA

[lofty rapids]

so your doing it in a loop, so multiply the timer interval by index

[crude glacier]

your so smart

thanks

[cunning zodiac]

Hi I'm feeling dumb. I'm trying to get my game to start with the bp pawn camera class i created. Its put into the default pawn class in the world settings. But it keeps loading under player start.

[lofty rapids]

wdym "under" player start ?

[cunning zodiac]

its going to the default player start position instead of the Pawn i made

[spark steppe]

is the pawn set to be auto possessed by the player?

[lofty rapids]

because you set default pawn class, the pawn will start at player start

wdym "instead of the Pawn i made" ?

[cunning zodiac]

In world settings I changed game mode default pawn class to the pawn I made

[lofty rapids]

and that spawns it at player start

thats what it's supposed to do, what are you trying to do instead ?

[cunning zodiac]

I'm trying to get it to spawn in the drone camera I made

[lofty rapids]

is it moving around and you want it to stick in there ?

[lofty rapids]

so you placed one in world, and this is where you want to spawn instead ?

[crude glacier]

woah, u can edit nodes wow

[cunning zodiac]

sorry, I'm new to blueprints so I must not be explaining correctly

[lofty rapids]

it's just that what is happening is the way it works where it spawns at player start

if you want something different there is different ways to go about it

[mental trellis]

You've explained yourself fine.

When you hit play it shoudl spawn your drone and possess it for you.

Should

[cunning zodiac]

I supposed I'm assuming the drone camera isn't working because the inputs aren't working. The mouse is moving around but the others aren't. But when I change the inputs to other things nothing changes, so I thought that meant it wasn't loading the BP_OpalHoverDrone at all

[languid pagoda]

look in your outliner when you hit play to see if it spawns

[lofty rapids]

and you have a player start ?

is there a camera on OpalHoverDrone ?

[languid pagoda]

The oddest part of this, is I unintentionalyl had it working when I set up my actual pause menu. My camera would move while paused

[cunning zodiac]

yes

[cunning zodiac]

doesn't look like it

[lofty rapids]

player start is where it will spawn

[languid pagoda]

take my advice with a HUGE grain of salt, but maybe drag an instance of the BP right into your level?

[lofty rapids]

when you hit play is it still the free flying camera ?

[cunning zodiac]

it's there

[cunning zodiac]

It just can rotate in place but cannot move otherwise

[languid pagoda]

and you set up your IMC and IA to move it around?

[lofty rapids]

you don't need to do this

this will make another player just in the world

setting default pawn will spawn

[languid pagoda]

This is how I set up my WASD for my free camera BP

[lofty rapids]

so it seems something with your inputs, can put a spacebar event in your character, and print string hello

so that if your character is possessed it should print hello

make sure your receiving inputs at all

which you should be

[lofty rapids]

set your player controller class here

your cast is probably failing because you have the wrong player controller in override

[languid pagoda]

yeah set a Print String on your "cast failed" to if it's failing like @lofty rapids said

@lofty rapids no ideas for my little problem?

[cunning zodiac]

okay thanks guys. I'll try that

[lofty rapids]

are both of these in the same bp ?

[languid pagoda]

negative, one is custom player controller, other is BP_Freecam

[lofty rapids]

^ this is probably the issue from what i can tell

[lofty rapids]

does bp_freecam have input enabled ?

it's really strange to do it this way as well btw

[languid pagoda]

like Input Actions?

[languid pagoda]

I wouldn't doubt that lol. I basically set global params in the Controller and things specific to the FreeCam (player)

[lofty rapids]

you can try this

but i think pause disables input

and thats the issue ?

[languid pagoda]

@lofty rapids this is my "slow time' that is working. First pic is in the BP_Freemcam, second pic is in the controller

[languid pagoda]

ok let me try that

[lofty rapids]

the difference is your not pausing

pausing the game disables input

[languid pagoda]

ahhhhh

[lofty rapids]

you may want to make a custom pause state

[flat coral]

I'm having a bizarre issue where an event dispatch from one class is being received like 11 times by another class. Look at the logs, one dispatch, received over and over and over again by the same actor.

It starts to get polluted by errors going array out of bounds, but that's just because it's only supposed to get ONE call and instead it's getting like 15

[lofty rapids]

neither of these images show very much, what is the accessing array of ?

[pallid cypress]

Hey Guys
I want to use the Level Blueprint to creat a click Event on the mesh insde the Blueprint on the level.
So in Level BP create something that clikc on the Mesh troso in the MetaHuman Character BP that is on that level. How to do it? Sorry I don't know if I'm telling everything clear

[flat coral]

Doesn't matter. The issue is the one-to-many Dispatch / Received

[lofty rapids]

you probably don't want to use level blueprint for this

[lofty rapids]

the issue is your accessing out of bounds

[pallid cypress]

what you suggest better?

[flat coral]

It's causing other issues too, like queing the same dialog 15 times

Yeah but I'm only accessing the array out of bounds because I'm getting 15 calls which each result in an "index++" operation when I hsould be getting 1

[languid pagoda]

@lofty rapids your solution worked, but its super blurry when I move the camera while paused. is that just an Unreal thing?

[lofty rapids]

create an actor, add a mesh component

use click on actor event

you may need to enable click events in your controller

[pallid cypress]

What I want to do is after you click on the Mesh the player cammera will come closer to that mesh

[lofty rapids]

yes you can do that i have done something similar with a zoom, where it zooms in on where your cursor is

[lofty rapids]

first thing you need the click event of the mesh

but you got to get it in the scene as well

are you spawning it, is it in the scene yet ?

[pallid cypress]

not spawning it's on the scene

[lofty rapids]

ok so do you have a custom player controller ?

[pallid cypress]

yes

[lofty rapids]

something to do with the setting you changed i would imagine

[pallid cypress]

so BP_Actor is the character where we have that mesh that need to make click action

[lofty rapids]

so you don't know what the player controller is so i'm guessing you don't have a custom one

[pallid cypress]

and this action will make the Camera manager change the camera location

[lofty rapids]

anyway you need to enable click events

in your controller

which you can do on begin play

[pallid cypress]

ok

[lofty rapids]

so goto content browser double click, the bp_actor

and on begin play ...

get player controller

[pallid cypress]

I have custom player conroller

[lofty rapids]

ok

in the details

enable click events

make sure it's checked

you don't need to do anything on begin play

if you have a custom controller

just make sure the box is checked

[pallid cypress]

?

[lofty rapids]

you don't need to do this

read what i wrote

[lofty rapids]

^

if you have a custom player controller

[pallid cypress]

ok I have

[lofty rapids]

don't enable touch events

[pallid cypress]

it's gonna be use on mobile later

[lofty rapids]

ok you can try it

double click on you bp_actor and go into the bp

right click and get event actor on clicked

then put a print string hello on that

and see if the click action works

[pallid cypress]

like this?

[lofty rapids]

yes

then run it

and see if it shows up when you click

run in viewport

or pie

so you can see the print

[pallid cypress]

yes works

[lofty rapids]

ok so thats the first thing you needed so that works

nice, so now do you want to go straight in ?

like zoom in ?

does your bp_actor have a camera ?

[pallid cypress]

no

camera have BP_Player

[lofty rapids]

huh ?

[lofty rapids]

camera is a seperate actor ?

ok so this is your camera actor

[pallid cypress]

my Default Pawn Class

[lofty rapids]

ok, so how is that setup in the bp viewport ?
