Build Faind error(crash) on packaged game when trying to set scalability to epic

Works fine in pie

[bleak wraith]

sorry for not being clear also.

[versed sun]

try #packaging , we havnt gotten that far

[vapid ice]

Kk

[supple dome]

no, unless its very arcade, (ie a tank in a turn based grid)

[agile ridge]

In that case, you'll want to get AllActorsOfClass(BP_TopDownCharacter) then you'll want a ForEachLoop that checks for that value. Then in LoopBody, Branch that checks if LoopIndex == Self(True, do nothing (as in don't plug it into anything), False (Get PlayerIndex(LoopIndex) then on the GetPlayerCharacter(PlayerIndex = LoopIndex). For this to work, you'll want to check for that value on BeginPlay and have PlayerIndex be a dedicated Integer Variable. It should work fine from there, assuming that there are only 2 actual BP_TopDownCharacter Actors in the actual scene. If there are more than that, the logic will get more complex.

Edit: You can also have the Variable just be an Object Reference for BP_TopDownCharacter and just plug that directly into the AIMoveTo Target.

[pine tiger]

I've got an actor component with a ptr to another actor in the level. Changing any values on the property at runtime causes the property to be remade, which seems to copy everything across except the reference, which goes nullptr.

This ONLY happens when the actor is part of a blueprint object, and doesn't happen when just placed on an actor in a level.

Any ideas of where I should start looking here?

Do I need to mark actor components with something other than BlueprintReadWrite properties? Seems like changing ANYTHING recreates the entire actor for every change.

[bleak wraith]

like this one ? https://www.youtube.com/watch?v=-wlmiQ5KpoY&t=215s
5:21

[agile ridge]

Yeah, sort of like that. Though you won't want the ForEach Loop to loop back onto itself. If the Branch doesn't find the correct index, just let it move on because the ForEach Loop will progress to the next index naturally once the code for the one it's on has resolved. Assuming you're talking about this up here:

I have to go work 5 hours left for sleep but thanks to you finally I can go sleep at piece XDD

[queen dagger]

Is there any reason why when casting to the playerstate that i cant call the player struct from the player state?

[dawn gazelle]

Because it's called Splayerprofile

[queen dagger]

ahhhh

so the real reason this didn’t work is cus im stoopid

[wise ravine]

Hello, so I'm making a game where the player rides a train between different stations. After a certain point the previous station will delete, and the next station will load, but it will be slightly different (like an anomoly). I was thinking I could store the different types of levels in an array, and somehow randomly spawn stations. Is this the best way to do this?

[dawn gazelle]

Not sure about the best way, but it sounds like it would work.
If you want to mimic Exit 8, you'd use an array as you mentioned and shuffle it, then pull from index 0, remove it from the array and load that level. If there is nothing at index 0 (you've run out of levels to load), you repopulate the array and shuffle again. You may also want to keep track of the array through save games, so that if there are unseen levels when they leave the game, save the array and use that the next time you load up so that they can continue to see the unseen first.

[wise ravine]

This helps a lot, especially since I'm just getting into arrays. I've never had to load and unload levels before, would that be something like sublevels explained in this video? https://www.youtube.com/watch?v=z5Yjnr7ryuA

[dawn gazelle]

Not 100% sure on that, but so long as there's some kind of seamless loading (you're not moving the player between levels) then yeah, that could be a potential solution. Alternatively, you could use actors to represent your levels and just spawn and destroy them as needed.

[wise ravine]

I see, would I have a 'hub' blueprints that spawns and destroys actors when needed?

For the alternative option....

I know you don't know for sure, but does that sound about right?

[dawn gazelle]

You probably always need 3 levels loaded.
The one behind you, the one you're in, and the one that is in front of you.
As you cross the threshold to the level in front of you (which can be an overlap collider), you can communicate with whatever to spawn your next level. Doesn't need to necessarily be a separate blueprint, but coudl be the gamestate if you want.

If you really wanted to mimic Exit 8 then going "backwards" usually indicates you saw an anomaly, so based on which way you go, it either increases your score or resets it if there actually was an anomaly or not, but in either case, it loads up a new level.

[undone galleon]

I'm having trouble understanding why I can't find this class. I can drag it onto the pins of a function and it'll assign properly that way, but I need it in my structure so I have a handy package of information of a perceived target.

An example of forcing it into a function pin; It's clearly available, but I can't pull it up in the var dropdown

[wise ravine]

I’ll keep this in mind. Yea i’m not too worried about copying another game because I’m still a very new game designer. I’m just worried performance wise, about having 3 levels loaded when each level is about 50k triangles

[hasty shard]

I have a question. I have a mesh, basic character without any clothes... I get a way to add cloth on it by creating another skeletal mesh on it (the cloths) so I juste need to change the asset into this one... and they share the same animation blueprint... is that a good way to do it, or it have better way?

[junior quest]

Where can I add to my show only actors list?

[wise ravine]

unrelated question: how do you change the color of the interface?

[junior quest]

its a plugin, its either darker nodes or electronic nodes

I bought it because I personally think it makes reading the graph editor easier

[dry pecan]

did I do this right? bullet will spawn and move in a single direction, floating like a bubble

[odd kiln]

On "Begin Play" take your "Scene Capture Component" and you should see a "Show Only Actors" Variable I think. Connect an "Array" of Actors into it

[trim matrix]

How does interfaces work?

[odd kiln]

Be careful you are using the "Set Timer by Event" node in the same "Event" again and again.. I don't think it's a good idea

[dry pecan]

why's that?

[odd kiln]

What are you trying to do ?

[odd kiln]

I think you have to have an "Event_01" to call another "Event_02" that is "Looping"

[dry pecan]

well I'm trying to have this actor here via blueprints spawn an object each 2 seconds that will float across the screen slowly

[odd kiln]

At which rate do you want your bullet float across the level ?

[junior quest]

Show only actors isnt showing up in the BP, i can only see it in the 3d viewport and I want to select the mesh of the BP

I want to use the 2d render as UI when the player opens the menu

[dry pecan]

I'd say at a walking pace, so 3 mph

[odd kiln]

Don't you have this node ?

[junior quest]

ye but not really

[dry pecan]

did I mess up?

[odd kiln]

Pull out from the "Scene Capture Component 2D" node at the botton and search for "Show Only Actors"

[dry pecan]

should I have used a different transform node?

[odd kiln]

To make your "Actor" moving each tick, you can use "Event Tick" in the BP of the spawned Actor

So in the actual BP, just spawn a bullet each 2 seconds like that

[junior quest]

I dont know what im missing

[odd kiln]

Then, open in the spawned BP, make your bullet moving "each tick" with the "Event Tick" node

[junior quest]

Im trying to follow but i dont get it

[odd kiln]

To be sure that I'm understanding correctly, you want to set a list of actors for the "Show Only List" right ?

[dry pecan]

so you mean to say I should have my bullets move on their own?

[odd kiln]

Isn't that what you want ?

[junior quest]

I put the 2d capture component on the BP to capture what would be a character ig, then when the player opens the UI or a speaker has text I want that character to show up in the UI. I want to set the mesh in the BP as the actor in the same BP

but im starting to think I might not be able to do that and I might need to separate things out?

[dry pecan]

can I ask how I would activate both custom events?

[stoic ledge]

sequentially call the events?

[odd kiln]

Is that what you want ? https://www.youtube.com/watch?v=BeX9Cobo3_c

[odd kiln]

You can call your first event to "Spawn" your bullet each 2 seconds whenever you want. On "Begin Play" for example

Then your event that is moving your bullet will be called inside the bullet Blueprint itself, when it will be spawned

[dry pecan]

so will the charcater I want to activate the bullet spawner call activate or the spawn evemt?

[dry pecan]

pressing K but my debug string isnt showing

[odd kiln]

Try to make a "Print String" and tell me if it's showing

[dry pecan]

odd still nothing

[junior quest]

ty that works, I was using a render target instead of a canvas render target

i think it will work at least

[dry pecan]

maybe it has to do with my enemy bullet?

[odd kiln]

Glad that it worked

[odd kiln]

Are you sure that when you press "K" something happens ?

Try to set a "Print String" just after your "K" pressed

[dry pecan]

I did and still, I even used event beginplay

[odd kiln]

So nothing is showing when you press "K" ?

[dry pecan]

weirdly

[odd kiln]

Maybe you set the code in the wrong Actor

[dry pecan]

I only use blieprints

[odd kiln]

You have to "possess" the actor to make the inputs working

[odd kiln]

Did you try to set a "Print String" on the Begin Play node ?

[dry pecan]

yes

[dry pecan]

I thought it just happens on its own? thats what I was hoping for

[odd kiln]

If nothing happens it means that your actor is not spawned in your World

You have to put your Actor in your World (Level) to make it running code

[dry pecan]

but I placed it into the world though

oh it is working

I think I may have done this wrong

[odd kiln]

This is in your Bullet blueprint ?

[dry pecan]

ye

[odd kiln]

The "Begin Play" node is executed only once

To make something moving continuously, you have to use a "Timeline" or the "Event Tick"

[gentle urchin]

Projectile Component ftw

[dry pecan]

like this?

[trim matrix]

Is there a game mode base for each map created?

[gentle urchin]

you could have

but its not made by itself

[gentle urchin]

this makes the bullet move 1 uu per frame

so at 20 fps you move 20uu/s
while at 100 fps you move 100uu/s

[dry pecan]

crap, I need it to move 5 mph

[worthy jasper]

Depends on your game. You might use the same game-mode for all maps

[trim matrix]

yea true

[gentle urchin]

5mph = 5 / 60 miles per minute = 5 / 3600 miles per second

oups

1 mph = 0.44704 meters / second
5 mph = 2.2352 m/s

so you want to do
GetActorForwardVector x Speed(2.2352) x DeltaSeconds

[dry pecan]

vector * float * float?

[dry pecan]

right or wrong? still not moving slowly

[gentle urchin]

You'd want to add that to the actors current position

so getActorLocation + (the result of your previous math)

[dry pecan]

ok they're moving but way too slowly

[odd kiln]

I think because in UE the default unit is cm/s

Try to set your speed to "253.52" maybe

[dry pecan]

IT WORKS!!

[odd kiln]

Glad for you !

[dry pecan]

I just need to get colision to work now

[odd kiln]

Tick the "Sweep" on the "Set Actor Transform" node

Whether we sweep to the destination location, triggering overlaps along the way and stopping short of the target if blocked by something. Only the root component is swept and checked for blocking collision, child components move without sweeping. If collision is off, this has no effect.

[dry pecan]

did I do this right? it checks the object iy hit and applys damage

[gentle urchin]

good catch, me forgetting to * 100 converting to cm 😛

[odd kiln]

I guess, try and see if it works

[dry pecan]

is there any way to have the bullets spawn in the direction of the spawner?

[odd kiln]

Get Actor Forward Vector of the Spawner

[dry pecan]

would I do that in spawner of bullet?

[odd kiln]

Yes you have to do that where you spawn the bullet

[dry pecan]

odd their still moving forward world wise but not to the spwaner

[dry pecan]

did I do it wrong?

[odd kiln]

You need to set the rotation into the "Spawn Actor" node

[dry pecan]

odd I dont see rotation

[odd kiln]

Right click on the "Spawn Transform" and split it

You will see Location, Rotation and Scale

[odd kiln]

Exactly

[dry pecan]

okay now this weird, the byllets arent facing the direction the spawner is facing

[odd kiln]

So what are they facing ?

[dry pecan]

the direction I rotate the spawner I placed in teh scene to, I use an arrow to show its front

[odd kiln]

So you mean if you hit "Play" and then rotate the Spawner the bullet is still facing the default rotation of the spawner ?

[dry pecan]

so the bullets would also move in that direction. also the spawner is already positions as needed, its just my bullets moves forward on the screen and not the direction the spawnder is facing

[odd kiln]

So the issue is the rotation when they spawn or the direction they move ?

[dry pecan]

direction

[odd kiln]

So they spawn correctly ?

[dry pecan]

yes

they spawn and move as they should

just not in the direction I want

[odd kiln]

So the bullet spawns with the correct rotation but don't move forward ?

They should move forward related to the code

[dry pecan]

essentially what I want is if the spawner faces left, bullets move left, spawner faces right bullets move right, same for up and for down

[odd kiln]

I need some screenshots of the issue

If the bullet spawns with the rotation of the spawner it should work cause the bullet moves forward itself

[dry pecan]

as you can see they are not moving in the direction my spawners arrow

[odd kiln]

The bullets are on the right ?

[dry pecan]

yes those object moving forward are bullets

[odd kiln]

And your spawner arrow is the red one ?

[dry pecan]

yes

[odd kiln]

And if I see it correctly their rotation are good, right ?

[dry pecan]

yes, its just direction

[odd kiln]

So they don't move forward related to themselves

Show me the code of the direction of the bullet please

They seem to move in the direction of the player

[odd kiln]

Can you split the "New Transform" and just set the location

[odd kiln]

No sorry I mean set the whole math thing

But only in the location pin

[dry pecan]

all pins?

[odd kiln]

I mean the math you did earlier to set the speed etc..

Take the pin of the "+" and connect it to the "New Transform Location"

[odd kiln]

Yes

[dry pecan]

still forward

[odd kiln]

Delete the "Set Actor Transform"

And use "Set actor location"

[odd kiln]

Yes connect it now

[dry pecan]

there we go!

ok now I need damage to work

seems that its not working, the moment it spawns it destroys itself

[dawn gazelle]

Could be because it's colliding with whatever spawns it. Add an owner or instigator to when you spawn it (it can be set to "self" as this then makes whatever was spawning it the owner/instigator). Have your overlap check if "other actor" != either instigator or owner (whichever you use) and only apply damage/destroy if true.

[dry pecan]

You mean via a branch?

[long breach]

you can also offset the spawn location for the actor so it doesnt overlap with the shooting thing

[edgy axle]

is there a way to do something like
const FVector Location = whatever
in BP, so it's read only for the rest of the BP but I can still set it at the start

if I try set it to Read-Only then I can't set it at the start of every tick like I need

[jagged sedge]

so it's read only for the rest of the BP but I can still set it at the start
can't set it at the start of every tick like I need
That means it's not read-only, that's a mutable variable

[edgy axle]

yeah I didn't explain that well

I need it to be hidden from the rest of the BP

[jagged sedge]

Do you mean local variables perhaps?

[edgy axle]

I can use like a pure function or macro to grab it but I don't want anywhere in the BP to be able to set it apart from a specific function

[edgy axle]

nah it's a normal variable

I mean this is pretty much what I want to do, but then make it so you can't set those variables anywhere else in the BP

only be able to read them

[jagged sedge]

I mean the UpdatedComponent is exposed right? You can just have pure functions to get those. That's about as encapsulated as it gets.
Do you need it as a variable explicitly?

Aside from that, you can't encapsulate a BPs variables from itself

[edgy axle]

I would prefer to use the variable

I guess the only other way would be to add a seperate component to handle that

[jagged sedge]

Seems overkill to add a component just for that

[edgy axle]

yeah I was gonna say that

[jagged sedge]

Would help to know what exactly you're trying to achieve with those variables, and why they would need to be read-only for the rest of the blueprint?

[edgy axle]

well it's for a movement component and I want those variables to be guaranteed safe so you get the same value anywhere in the blueprint

meaning it's kinda gotta be read-only in the rest of the blueprint

and I'm just being abit picky as well cause I don't like calling Get World Locatione etc every time I need it

[jagged sedge]

Why do they need to be read-only?

• Because they need to be read-only.
  Not helpful 😄

I'm just being abit picky as well cause I don't like calling Get World Locatione etc every time I need it
What would be the issue in doing that?

[edgy axle]

I just said why the needed to be read-only wdym?

[edgy axle]

^

if it's not read-only then it could get changed somewhere in between so the variable couldn't be considered fully safe

[jagged sedge]

Running in circles here 😄

[edgy axle]

not really

[drowsy anvil]

Hello, I made a moving projectile that hits an enemy, but nothing gets print stringed with this code when they hit? what type of collision do I need or what to fix? nothing seems to work to make it print

even with block all, the bullet still goes thru the floor

[maiden wadi]

I'm 99.% sure that the root of your actor does not have a blocking collision.

[drowsy anvil]

here's what I have, I've tried mixing what is blockall or overlapall or making them both the same, idk really what I am doing, which object should I make what?

I tried without the added sphere and box collisions too

[jagged sedge]

DefaultSceneRoot is your problem I think

[drowsy anvil]

when I search for collision, it says I cant add one?

just gives me this

[jagged sedge]

Replace the DefaultSceneRoot with your "Projectile" static mesh by drag & dropping it onto the DefaultSceneRoot

[drowsy anvil]

seems the code is now doing something, things get deleted, but the bullet became huge

[jagged sedge]

Call it a feature

[edgy axle]

it reset the scale because you changed the root

[drowsy anvil]

it almost works now, thanks for the help

[jolly oriole]

Hey everyone, I'd like my actor component (AC_TargetingSystem) to handle its own "get overlapping actors" call. The problem is I have no clue how to give (ie, feed through) the actor component the collider I'm using in the given blueprint.

I wish to use any collider, box, sphere, mesh, in the future.

This is important because I'd like the targeting system to run on its own tick every frame and check for things without relying on the parent actors to run it on tick.

Is there a parent object type I could feed through? My only other solution rn is to feed through an object using an interface or base class, which can be asked for stuff in its range. Then its just a case of making various of those objects.

[dark drum]

You could get owner and get components by class using Primitive component as the class type. You could further refine it by adding a tag to the primitive component you wish the targeting system to search for on the component.

[jolly oriole]

Oh hold up, that's really smart, using tags to find the correct component. The only potential issue are situations where I want to use a mesh as a collider (overlap) rather than primative. I suppose I could use logic via tags, or just some simple checks, to determine what kind of object it is?

[dark drum]

A static mesh is a child of primitive component so will be picked up.

[jolly oriole]

That's really cool. I guess the only way to make the component self sufficent is to have it try and find that prim, right? From what I can tell, there's no way to configure it in editor (similar to the 'instance editable' thing)

Other than running some kind of initialization function where I feed it that primative

[dark drum]

On the begin play of the actor component just run something like this. It would then just be a case of adding the tag the the primitive you want it to use in the actor. Of course you should add some additional checks to make sure it finds a valid prim.

[jolly oriole]

Amazing!

[edgy axle]

Apparently there's a issue with Catch2, I just found out cause I tried rebuilding the project completely and it said the same error as in this: https://forums.unrealengine.com/t/ue-5-4-compile-error-catch2/1770453/12 I'm pretty sure this is the thing stopping the project from properly being re-generated.

just wanted to put that here in case someone else is having the same issue

[jolly oriole]

Looking good; this also allows me to have multiple colliders if I want, which opens up some future stuff. Probably won't use it but it's a nice to have.

[dark drum]

Yea, the get component by class nodes are very powerful and add a lot of flexability.

[compact fable]

Heys guys! Would like some advice on how to set up end of level rewards.

Currently when a level ends, a score is calculated, the player returns to the home base.

Best way to implement how to get the score if its high enough will unlock the reward

[jolly oriole]

Where is your score currently calculated and stored?

[compact fable]

currently in the end of level widget

[jolly oriole]

It'd be good to put that logic somewhere else with a more "global" scope, perhaps your level blueprint or even on your character, and then do the final calculation there too

And you could just do a greater than check on your score vs your threshold to determine if it's met the requirement to get the final reward

[compact fable]

the check, would that be in the player character as well?

[dark drum]

I wouldn't do it in the level BP, this will just result in a lot of copy pasting logic.

[compact fable]

what about the game mode?

[dark drum]

I would probably create an actor component that manages the score and place it on the game state. When the level is completed, this component will then check the score and decide what UI it should show and if nessasarry, give rewards to the player.

[compact fable]

gamestate?

[dark drum]

You can create a new BP using the game state as the base class and then you can set your level to use it in the Game Mode.

[compact fable]

@dark drum could I use the same gamestate for every level?

[dark drum]

You can if you want too, you would need to include some logic in the actor component to determine what level the player is currently on so it can check the score correctly and give the right reward if needed.

[compact fable]

is does mention best not to use game state for player specific things

[edgy axle]

technically, you're wanting a level-specific thing

end of level reward isn't player specific

[compact fable]

okay, so game state is okay here?

[maiden wadi]

GameMode should house the granting logic along with the level ending logic. It's authoritive and should be server only.

Scores should life on PlayerStats. GameMode should be able to get playerstates and grant rewards based on the end of game's current state.

The data should also be put in a data asset for better data oriented design based on what gets granted for what scores, etc.

[edgy axle]

^

[compact fable]

so you are saying should be stored in a player state class?

[dark drum]

What determines the score? is a global score or specific to the player?

[compact fable]

the remaining health, amount of time elapsed, amount of items collected

[maiden wadi]

These all feel player specific.

[compact fable]

they are

[dark drum]

I feel like only the health is player specific haha. The other two could be specific to the level. You could just put the actor component on the game mode itself.

[maiden wadi]

Players can take different amounts of time to complete, and collect different amounts of items.

[edgy axle]

time elapsed is the only one that doesn't sound player specific to me

items collected are pretty specific

time elapsed could just be from the level time

[maiden wadi]

Not always.

[edgy axle]

depends on how they're calculating time elapsed

ig

[maiden wadi]

PlayerA can die, stop, finish before PlayerB in some game cases.

[edgy axle]

might be a singleplayers game

[compact fable]

it is a singleplayer game

[maiden wadi]

We can just put it all in the level blueprint then. 😂

Kidding. Please don't.

But in that case it doesn't really matter in the end unless you want to follow common design. But yeah time taken becomes more global at that point.

I use my own premade systems so I'd be inclined to just use my inventory component for the collected items.

I'd use GAS's attributes for the health. But in BP only land it's fine enough just to have some floats on a player related class. But it should probably go on the character or the playerstate. Character if you never really die or only care about the end health. Playerstate if you kill off the pawn for like restarts or whatever.

[compact fable]

@maiden wadi I guess playerstate then

and is there an easy way to get that data from the playerstate into the end level widget?

[maiden wadi]

GetOwningPlayer->PlayerState

And cast it, cause that will be APlayerState level

[dark drum]

The widget probally won't need to get it. The component managing the score at the end of the level would decide what widget to display and pass the relevant data to it to display.

[compact fable]

okay, will give it a try

giving it a try with the health scoring first, how do I keep them updated?

this is how I am getting the player health score in the PlayerState

I think it is best to get this scoring at the end of the game?🤔

[frosty heron]

Are you getting health or setting total score?

Why the function name

Not sure if I would ever use interface for something forward like this too

Why not just get player state, give me my health

[compact fable]

yes sorry thats what I might do

I just copied what was from my widget where I originally got the scores

this is my player state though

[frosty heron]

I'm not understanding then, player state is where you would have your attributes live, if you are going with player state route

So maybe you want to keep your health in character but score is kept in player state?

[compact fable]

yeah that is what I am doing I think

[tulip anvil]

Does anybody with a brighter mind then mine know why this doesnt work:

But this does:

[versed sun]

Case Sensitive name ?

[tulip anvil]

capitalization is correct.

[versed sun]

avoid By Name, it just adds headache later

there aren't any Inputs on DealDmg , is there ?

[tulip anvil]

well i can easily just make it an event. and thats not really the issue. but as far as i can find in the docs and in tutorials, this should work.

[tulip anvil]

there are but the entire function is never called in the first example. Even the print string is never printed

in the example images i just had not hooked the char ref back up.

[versed sun]

yah , Timers dont work with Inputs

It cant remember what the input was after the delay , or something like that

[tulip anvil]

but that still doesn't explain why the entire function isn't called does it?

like even if i remove everything and leave only the print string it doesn't print it

[versed sun]

the Set Timer By Event used dmgtemp, with no input , thats why it works

[maiden wadi]

Likely reason is the argument.

[tulip anvil]

and when in debug view it is visible the timer gets called but the function does not.

[maiden wadi]

Yeah, what Ryck said. 😄

Also, you should prefer to never use written names like that. At most use a CreateEvent node.

[tulip anvil]

okay but then why does this also not work?

i will just swap to an event for it, but i'd really like to know why it doesn't work when every example of this shows it functioning like this.

[maiden wadi]

Capital T

And if people are using examples using the named version, they're bad examples.

[tulip anvil]

thats the auto capitalization of the node if you look at the function in the list its not capitalized

[maiden wadi]

Should technically work. I'd be curious to know if it works as an Event instead of a Function.

[tulip anvil]

as an event it works perfect. even if i call the function from a custom event and timer by event it works. just not directly from the timer by name

[compact fable]

@maiden wadi sorry to bother you again, I was able to move all the end of level scoring logic to the Player state, tested and it works on the end level widget.
I was wondering how to do the end level rewards if any.
The reward is pretty simple, the player will unlock a new character skin if they get a high enough score, Also the skins if they are unlockable are set in the save game as booleans

[maiden wadi]

🤷‍♂️ Dunno. But I'd still really avoid using the named one. Someone can cause a bug by coming along and renaming the function with no immediate issues showing. CreateEvent is an easier way to not use a custom event node. And it'll only let you pick the functions you can actuall call.

[tulip anvil]

thats very useful. will do that from now on.

[maiden wadi]

As singleplayer I'd probably just keep the savegame object around in the game instance and write to it as necessary. Then your end of game can just grab it and set your skin thing to true of it wasn't already.

[compact fable]

I don't think I have a game instance 😓

[tulip anvil]

minor follow up question, as the function does not show up in the create event list?

oh wait does that also not support inputs?

[versed sun]

you cant use a Function/Event with Inputs

[compact fable]

Think it has to be a custom event not a function

[tulip anvil]

in which case how do i cast the damage to the player?

[tulip anvil]

i'm just asking to improve my workflow, as i can hack it together with a custom named event. but if there is a better/more optimal way i'd rather learn that 😄

[tulip anvil]

hmmm whats the advantage of this over directly hooking the event into the timer?

[versed sun]

Clutter and preference

[tulip anvil]

fair point

[versed sun]

thats perfect for that use, but sometimes the red wires clutter up the graph

[jagged sedge]

Whether you like nodes or wires, yea

[tulip anvil]

yeah that makes perfect sense. thank you so much for your time and explanations both 🙂

[tepid raft]

https://www.youtube.com/watch?v=khjUY5To7qI&t=1094s i used this video to make a inventory system and now want to make it so if i use something like a door key thats in there it goes away and not sure where to start do i start making a door lock and key or wat very confused

[wise raven]

is there actually a way to expose these constraint parameters into the graph?

[versed sun]

they usually are, what are they in?

[wise raven]

physics constraint component

[versed sun]

hmmm, I dont see it, might not be exposed to BP

[wise raven]

so its true that its not exposable to bp?

[versed sun]

Sometimes it is inside a struct that you have to change , but i dont see that either

[wise raven]

neither do i

[compact fable]

My game instance isnt working.
Created the game instance and have a save game and load game function.
For testing purposing saving and loading one unlockable skin.
Then in my skin selection widget, I call the load game. which should load the game.
but when clicking the button to select the skin its returns false

[wise raven]

did one of the engine devs forget to make it exposable to bp?

[versed sun]

maybe , or there could be something about it that would break if changed in game , so the didnt expose it

[blazing kiln]

sometimes the var is boueprintReadOnly for the purpose of limiting your excess to it, but there might be a helper setter function for it

you can have a struct to store data but never expose it for BP if there's a posibility of braking the logic with direct setting of the data

if you really want to get excess you can make a child of the class you're working with and add a setter function

not always a good idea though

[wise raven]

a setter function ?

[blazing kiln]

yeah

[wise raven]

it doesnt offer a way to set in bp

[blazing kiln]

yep, but cpp can do it )

[wise raven]

https://forums.unrealengine.com/t/set-angular-rotation-offset-through-bp/113762/8

just found this, and yeah it mentions changes in cpp as well

then i wont be able to update the engine

[blazing kiln]

nah you dont have to change engine code

idk the specifics but

[frosty heron]

you extend it in a sense

[blazing kiln]

if there's a class you use, like camera manager, you can make a child of it, add some logic there and use it instead of the engine default class

[frosty heron]

from the link

[blazing kiln]

yeah

[frosty heron]

no touching the source code required

[wise raven]

ok understood

[wise raven]

sounds fine then

[blazing kiln]

yeah that's exactly what i'm talking about

[wise raven]

so ill have to replace all my base constraints with the new cpp version?

[blazing kiln]

sorry if i mess up the explanation, not a native speaker )

yeah you can do that

since it's a child all cast will still work

should not be any problem in most cases

[wise raven]

i see

[blazing kiln]

just dont forget to call any parent super's if there's any

[wise raven]

parent supers? i didnt get that XD

[blazing kiln]

let me recall the BP name...

this

but you should probably call those in cpp child if you're extending the logic

[wise raven]

isee

[wise raven]

yeah that should be done automatically

[frosty heron]

if you are not overriding any function, don't worry about it

[wise raven]

ill give it a try and let you all know

[frosty heron]

make sure you have source control

installing required components to add c++ class might take you a while

[blazing kiln]

protected:
    virtual void BeginPlay() override; 

void ATZ_EnemyBase::BeginPlay()
{
    Super::BeginPlay();
}

like this

[trim matrix]

wut

[wise raven]

i have visual studio

[frosty heron]

still need the required components as stated in the doc

but gl anyway

[blazing kiln]

he'll probably have to override some if he's extending, no?

[trim matrix]

I think that
virtual void BeginPlay() override;
shouldn't be there

[frosty heron]

From the example, it's just a setter and getter function

not overriding any existing function

[blazing kiln]

probably true

[frosty heron]

can always call Super if paranoid

[wise raven]

tbh ive never touched cpp much at all before so idk how tricky this may be lol

[frosty heron]

good time to dip your toes

[blazing kiln]

for your case this is pretty simple to do and no overrides needed

[wise raven]

lmao i guess

[blazing kiln]

well you probably gona hate it for some time XD

but it's super nice to have cpp at least on a basic lvl

[wise raven]

ive always hated it

[wise raven]

yeah

[frosty heron]

can't really code without plugin

Intelisense is broken and can't understand Unreal Macro

[blazing kiln]

i hated cpp really bad before i droped VS and switched to Rider

it's much more friendly imo

[blazing kiln]

yep

i still get some stupid errors sometimes as most people do XD

today had the module missing in build.cs and i had no clue that it should be there )

[wise raven]

rider is an easier way of visual studio?

[blazing kiln]

imagine intelisense working for starters )

[frosty heron]

same thing, it's just preference. JetBrains have the plugin for Visual studio, it's called Re-Sharper

[blazing kiln]

it also adds includes and offer making basic things without you doing it manualy, i't just quality of life things

[frosty heron]

if you are student, you can get the lisence for free in the meantime

[blazing kiln]

but not if you're a student of a wrong coutry lol

[tulip anvil]

That is not source control.

you should really look into setting up source control as a priority if you do not have it yet.

[dense thicket]

what is a "Switch Case" called in UE ?

[versed sun]

Switch on Int
Switch on String
Switch on ENUM

Or Select if you want Values

[dense thicket]

perfect.. haha thanks, thougth there was just a "simple" on, so didnt try those

[undone nebula]

hey, would anyone know what i would have to do to make this blueprint only activate if a specific mesh overlaps with it instead of any?

[waxen mason]

From the "Other Actor" pin, use a == node and plug the specific reference you want

[undone nebula]

thank u

[tepid raft]

trying to make keypad door but for somereason when i walk it opens the door

[thin panther]

it helps if you show the code that actually opens the door :P

[tepid raft]

sry

[thin panther]

Even if the door hasn't been opened, you're closing it on leaving.
So when the door is it's neutral state, you leave the box and open the door backwards

you aren't checking to see if the door has been opened, before you close it

[tepid raft]

Ah so I pulled a stupid

[prisma crag]

Having an issue with 5.2.1, When I'm going to promote something to a variable it doesn't also let me set the variable. This is what it ends up doing (Even though when I'm trying to promote it to a variable, I keep dragging it off from "As Unit Base"

[bleak wraith]

anyone know why ? 🙂

[prisma crag]

this is what I'm trying to make it do, since I know I didn't explain it very well

[dark drum]

If I use the add component node to add a component to the actor, who is the owner of the actor? the BP that called the node, or the actors it's been added to?

[placid cove]

hi guys, i have this float that i want to divide whenever the boolean is true, any way i can do it without making a branch?

[dark drum]

Select node, set the divisor to 5 if true, 1 if false.

[thin panther]

Looks like this might be a mixamo animation?
Anyway, it looks like the pelvis is your root bone, and it's not a root motion animation, so the root bone remains locked in place

[placid cove]

yeah, perfect thanks

[bleak wraith]

yes its from mixamo and I retargeted before and it was working well however, when I made another BP for enemy npc it started behaving bad. How can I fix it exactly?

[thin panther]

you'll probably want to enable root motion

[bleak wraith]

this meaning it has active root motion?

hahahhahah now it get more funnier

[undone nebula]

is there a way to activate an input within a blueprint? So that after a trigger occurs, the menu opens up naturally without the player having to press Esc to do so?

my game is within VR and I have used the VR menu where it appears on the players left hand and you use the right hadn for navigation (pointer)

so its not like a main menu or anything

[rotund barn]

incase no one gives a better answer in a timely manner, ill give my 2 cents (im a complete beginner), there is a blueprint node called "press key", which allows you to select a key press internally to happen when whatever you hooked it upto triggers.

i just hope im not completely misleading you

[undone nebula]

youre not

i think this would work

but i cannot find the oculus quest keys within that list for some reason 😭

[broken wadi]

You mean like a custom event?

[undone nebula]

kinda

[broken wadi]

How should it get triggered in the first place?

[undone nebula]

once completing the game, the menu pops up

[rotund barn]

well you could add an extra button in the DMC and use that, i think

[undone nebula]

idk if youve ever used the VR template before

[undone nebula]

yeah that is what i was gonna do

[broken wadi]

Okay so once completing the game you just call a custom event that does the same thing as your input is already setup to do.

[undone nebula]

if i just add escape to this it would work

ill give it a try

[broken wadi]

Escape will close the PIE window but works in a packaged build.

[undone nebula]

ah yea

ill just use P

[broken wadi]

I setup two keys, escape and another for testing

yeah

[undone nebula]

if you use P within VR then its a them problem at this point

i got 7 hours until deadline for this assignment and i quite frankly couldnt care if thats not an industry standard

ive had too many issues with packaging to care about this now

[rotund barn]

good luck! and as long as things work, it doesnt matter what happens under the hood.

[undone nebula]

thank you for ur help

both of u

[undone nebula]

did you mean like this? or am i doing it wrong

as it does stop other actors from overlapping and triggering the vent

but it also stops the gold bar (which is the item i want to overlap)

from triggering it

[waxen mason]

I´m not sure why the Bar is not triggering it, but instead of selecting it, try and create a reference to the gold bar itself and plug it

[thin panther]

Don't focus on calling the input, just invoke the code that the input invokes

instead of key pressed -> do thing and something happens -> fake press key
just
key pressed -> do thing and something happens -> do thing

[waxen mason]

Wait a sec, how exactly are you trying to open the door, because usually you get a collision box that activates with a specific actor (in your case the mesh) but in the BP i see Actor Begin overlap

[waxen mason]

Try to add a collision box and use "OnComponentBeginOverlap" see if it works then.
Place it in the place you would drop the gold bar

[undone nebula]

this blueprint is within a pressure plate, after this pressure plate is activated it opens a door

i’ll show u it all when i get back on in 2 min

Pressure plate BP

this is in the door bp

[undone nebula]

alreadyhave this

it worked perfectly with any kind of actor that overlapped it before i added the ==

[thin panther]

That will be checking for a very specific actor.
What do you want this to respond to?
A certain specific instance of an actor, a certain type of actor, or a certain mesh contained in an actor?

[undone nebula]

okay so

in the game, its an escape room for VR

you find a gold bar in a hidden room, you pick it up and then drop it on the pressure plate which allows you to open a door

[thin panther]

and it has to be only that one gold bar?

[undone nebula]

yes

well theres 3 of them in the game

[thin panther]

And any of them can be used?

[undone nebula]

yep

[thin panther]

Do all 3 need to be used?

[undone nebula]

no

[thin panther]

Or just any 1 of them on the plate

[undone nebula]

just any of the 3

yeah

[lofty rapids]

is that >= the same variable ?

[undone nebula]

yes

[thin panther]

Does the gold bar have a base class that isn't an engine class?

[undone nebula]

just realised

[undone nebula]

dont know what you mean

[thin panther]

I.e. did you make a base class for it in bp?

or is this just a static mesh placed in the world

[undone nebula]

nop

its a blueprint just placed in the world

i can add it to a class and then reference the class instead of the bp in the code?

[lofty rapids]

any reason why you don't cast ?

[thin panther]

So, you could cast other actor to the type of the blueprint

[undone nebula]

because im shit at development lol

i have to finish this course to get the degree anyways

i prefer 3d arts and technical arts

[prisma crag]

Any clue why it's not letting me select the UnitClass on the BattlePosition?

[thin panther]

Alternatively, add a tag to each gold bar in the world, and check if other actor has the tag, with the ActorHasTag node. It's not scalable, but if there's only ever 3 gold bars, and this isn't being used across levels, it's not an awful solution

[undone nebula]

so this?

[thin panther]

You could also have an array of actors on the pressure pad, click the eye icon, and then add each gold bar to the array on the pad in the world. Then check if other actor is in that array on overlap

[lofty rapids]

is it comming back not valid ?

[waxen mason]

The GoldBar also has to have that tag if you are going for that approach

[prisma crag]

It's just not appearing as an option at all, it should be appearing as a drop-down menu on the battle position units to choose what one will spawn, though it's just not appeared at all

[lofty rapids]

what is is enemy placement boolean supposed to be doing ?

it's a variable you set, but i don't see where you use it

[lofty rapids]

oh are you saying unit class is not in the defaults ?

probably because it's private

[prisma crag]

Nvm, I sorted it-- I forgot to make it Instance Editable

sorry again

[remote rapids]

i need help in blueprint in unreal engine
can someone help me?

[lofty rapids]

possibly

blueprint*

[undone nebula]

yeah ive done that

thanks

[maiden wadi]

It's usually best to just frame your problem and expectations. If someone can, they'll reply.

[remote rapids]

https://www.youtube.com/watch?v=zt13VcimeyI&t=2740s

so

[remote rapids]

when i done this everything work like the video

[remote rapids]

go 58:00

[remote rapids]

and my problem is here
after i finish that the enemy doesnt move at all
and the perpuse in this blueprint is that the enemy will chase me

[maiden wadi]

You're missing a white line.

[lofty rapids]

you chase is missing an execution line comming from it, unless you disabled it for some reason ?

[thin panther]

If he doesn't move, ever at all, do you have a navmesh as well?

[remote rapids]

i fix that now and the problem is not solved

[remote rapids]

i did exacly like the video

i dont know how to solve that

[ocean pier]

Anyone know why it is only putting the image on half of the screen? I have a curved monitor if that is doing anything to it

[remote rapids]

i am waiting... thunks

[remote rapids]

fix and not solved i steal have the problem

[lofty rapids]

is the ai moving to 0,0,0 ? and is the problem that your running chase but it isn't doing anything ?

it would most likely move to 0,0,0 and just stay there

[remote rapids]

the problem is that before i wrote that

the enemy was moving

like in the video link that i send

[remote rapids]

and after i wrote that image

my enemy doesnt move at all

and he should chase me

like in the video link

https://www.youtube.com/watch?v=zt13VcimeyI&t=2740s 58:00

when i run he should run to me and when i stop he should stop with me

[lofty rapids]

well your chase just says to goto 0,0,0

[remote rapids]

so why in the video that i send

that work for him

when the Destination is on 0,0,0

that work for him

[lofty rapids]

does your wander work ?

does the ai move around ?

[queen dagger]

question, can you overide the default spawn actor to relate to player controllers?

im struggling to get the character selected spawn working

[lofty rapids]

the target actor is your player character, are you possessing a character ? or is the camera free flying around ?

[remote rapids]

i dont know, i am steal learning the software, can you call me maybe in private and i share screen

?

[thin panther]

Have you ever dragged a navmesh bounds into the scene

You'll know if you have

[lofty rapids]

i noticed you set the target so it 0,0,0 should be fine if your character is there

[thin panther]

In fact, just show your scene outliner

[queen dagger]

thats what i got so far

[remote rapids]

you mean that @thin panther

[thin panther]

yep, so you've got one

[remote rapids]

i did like in the video everything shpuld be good

[dusky cobalt]

Try to create event from the start or set these functions again. Not sure why you have different names. Try to call it again.

[lofty rapids]

i'm just going through the debuggin i didn't and am not going to watch the video, it could be several things

[ocean pier]

Anyone know why it is only putting the image on half of the screen? I have a curved monitor if that is doing anything to it

[remote rapids]

how to do that/

?

i am new in this

[lofty rapids]

i don't think the curve is a problem, it does this when you pie ?

[dusky cobalt]

Try to check in the right top corner settings in the widget you have settings like desired size etc. use full size or something like that, if you have set desire size

[remote rapids]

can someone call me on private pls and share screen with me pls

i want to finish that

and move on

[dusky cobalt]

1. Delete all 3 events you have that are called Chase.
   2.Create new red custom event, call it Chase.
   3.Call this event in these 2 places.

Also I might see the problem. Do you have 2 characters one is called Player and one is Enemy?

[remote rapids]

you mean to create 3 custom red ? and call them chase?

[dusky cobalt]

No, create 1 event called Chase

and then call it

[remote rapids]

i have that

[ocean pier]

this?

[dusky cobalt]

Yeah, here, and you can try to play with your size, maybe try to do 1920 1280 or something like that.

[ocean pier]

oh ok thanks

[remote rapids]

like that?

[dusky cobalt]

yes, but delete it and do it again

[remote rapids]

i delete those 3

and did that again

is that good?

that steal not good

i have the problem

[dusky cobalt]

go to view port (where you see your player) and click P

and send me screenshot

[remote rapids]

v

[dusky cobalt]

from the level, from your map

[remote rapids]

that?

[dusky cobalt]

yeah

where is your Player Start?

[remote rapids]

i dont know

[lunar sleet]

Did someone steal it? 🙃

[dusky cobalt]

put it into the level, on the map

[remote rapids]

omgggg

thunks

that worked

what was the problem??

[lofty rapids]

you were not possessing a character

[dusky cobalt]

this is reference to the ''Player Start'' in simple words

and not to the BP_Player1

if you wanted to put BP_Player1 in the world

thn you would have to change it here

to instead Get Player Character, use for example Get Actor Of Class

and then you choose class BP_Player1, of course its not perfect way but it's brute forcing 😄

[lofty rapids]

if your on a video and something seems wrong, you'll most likely need to go back over it you missed something, or even i have seen sometimes they correct mistakes later on which is a pain

[dusky cobalt]

Also my advice, watch video first on 1.25x, cut your hands with knife

and then watch it again slowly and repeat things from video

i can guarantee you if you try to follow video step by step, you learn nothing

you are not paying attention to what he is saying, how it works, your brain only cares on repeating what you see

[remote rapids]

i understand thunk you very much!!

[remote rapids]

yh but i didnt know where i was srong becuase everything was looks well

[lofty rapids]

i learn well from videos, i just pause it and try to understand and mess around as i go

[remote rapids]

i didnt fukky understand you, can you explain me again how to learn well from the video?

[dusky cobalt]

yea it can work if you already are familiar with basics 😛

[dusky cobalt]

You can watch video on 1x speed or 1.25 speed first, but don't try to repeat things that the guy is doing in the video. Just watch. When you finish, watch again, this time repeat what he is doing.

[remote rapids]

ok

thunk you

you realy helped me a lot

[dusky cobalt]

https://www.youtube.com/watch?v=79MM83fnFUI&list=PLziQlhUd357jEk5y77AHniPa2ywcMExlG&index=1

[remote rapids]

and @lofty rapids thunks us well bro

[dusky cobalt]

I recommend this for the start

[remote rapids]

okay

[dusky cobalt]

https://www.youtube.com/watch?v=IipvT6aGinM&list=PL2A3wMhmbeAq3WOT7kQ0EGby1YMb0zj5_&index=1 and then this is really good

first is short things you need to know, and 2nd one is really detailed one and slow so you can take time and understand everything

[hearty tartan]

I want to populate my variable in blueprint by passing it in on the command line:

mygame.exe ?charactername=Bob

[lofty rapids]

probably c, but you usually don't use a url query like that on the command line

ig it wouldn't matter you can parse it, but i'm not sure you can do it in blueprint

[random pulsar]

guys hello

i am trying to make a door that opens if you rotate correct a few objects
i have a door blueprint and a claw Mechanism blueprint ,i just can get how to link this ,i made also a blueprint interface and a trace in character

can anyone explain how i link them

and also how to store the correct combination

and where to check it

[main lake]

is there a way to make BP nodes linked together with the exec pin + other pins align itself only on the "exec" pin when pressing "Q". Because it keeps aligning by taking the average of all the pins and it doesn't look perfectly aligned when it does that. Here's an example with 1 node + a branch you can see the white line isn't perfectly aligned nor the redline

[dusky cobalt]

https://www.youtube.com/watch?v=YFtLd-bKl-U

[dusky cobalt]

If it happens you can discconnect the boolean or others that might collide with the Q and then connect it again. I know it's not the best solution. Also search for flat nodes in unreal market place, they are a little bit better.

[lofty rapids]

you could have them in an array, and loop through checking the rotations, just put them in a specific order, if they all match switch a boolean or something

match against an array of rotations, or even a variable for the state if you hard code the rotations

[main lake]

I already do that but I want a final solution to not have to do that over and over again each time. I already have the plugin "Electronic Nodes". I don't like the esthetic of "Flat Nodes".

[latent venture]

Does anyone know why are those variables private?( first pic)
I created this widget blueprint: (second picture)
when i change the title in the blueprint it changes, but when I go to an another widget blueprint i can`t use it? why?

[upbeat magnet]

I just have to say, after spending a couple of days creating materials and having the cleanest looking material graphs that I've made in years, I sure wish normal blueprints had named reroute nodes.

[storm stream]

Hi, does anyone know why my branch doesnt work property? I want to select enemy data though percent change and for this i generate random float and use operator with branch on loop, but code somehow still selecting data what has 0 % chance to select.

[young meteor]

I've been cleaning up Blueprints with custom events and calling those. Maybe that might be something for you too?

Not the same, but still..

[young meteor]

Is it on purpose you are setting "Tool tip text"?
(First screenshot)

[latent venture]

you are right

that was the problem, it was a mistake :)))

[dawn gazelle]

Pure nodes are executed for each "pull" off of them. You're basically getting different random numbers a bunch of times from here.

[storm stream]

Why branch detect 0 > 0.1 as true :_: what wrong with my code

[dawn gazelle]

The solution is to promote the random number to a local variable and use that to feed into your GET.

[storm stream]

Ohh! I do that to float, but forgot about integer

[remote rapids]

when i opened my saved project i have black screen

why is that?

@dusky cobalt @lofty rapids

[lofty rapids]

your level is named Untitled ?

the outliner doesn't show much thats odd

[remote rapids]

i need to drag testing4? this is the last save

[lofty rapids]

file open

[main flume]

Does anyone know how to make my own procedural road system with intersections and traffic lights? And roads that I can connect, like highways and such, especially with road markings and such?

[broken wadi]

Would this be part of gameplay like a city builder? Or is this more like an editor tool so that you can speed up development times for making static meshes in a desirable layout? If its the latter then check out #pcg-framework that's going to be helpful.

Oh cool just saw that you can use PCG at runtime now in 5.4

[maiden wadi]

You can use it at runtime in 5.3 too.

[broken wadi]

PCG at runtime seems like it would cause some massive hitches. There has to be some sort of pause in gameplay for it to work properly imo. Something like the way level's load during an elevator ride in the half-life games.

[faint pasture]

What's procedural about it?

[faint pasture]

where the roads are? Or just the placement of things along a set road?

[random pulsar]

i made the array and compared in for each loop like you told

[dry scarab]

i need help my code doesn't change my box color any idea , As u can see in 2nd picture it def has random color its just refuse to aplly to box

[faint pasture]

The general form for things like this is to check for success whenever something changes

[random pulsar]

and the door rotates even if the clows are not 0 0 0 grades

[faint pasture]

because your code will open if any single one of them is at 0 rotation

Literally make a function called CheckForSuccess

in there, do your check. Have it return a bool

It'll be like this:

For each Thing -> is it in the success state? -> false -> return false
-> loop finished (all of them were successful) -> return true

[dry scarab]

i just found this cant put my m_color in

[lofty rapids]

did you fill the array anywhere ?

[dusky cobalt]

Get Material > Create Dynamic Material Instance > Set Vector Parameter Value > Set Material

[lofty rapids]

you created the instance but where did you actually apply the texture ? or set material ?

[random pulsar]

i made it instance editable in the door and assigned each of them

[dusky cobalt]

@random pulsar this is wrong way to do it, but for each thing that you did correctly, you can add it to array, when the array length is equal to 3 then you set boolean true and open door

[lofty rapids]

or even just a count

integer

[dusky cobalt]

so in each item that you have / can interact with you have function that increases the count or array

[dry scarab]

so im following this guys code lol, i gueess he has other code else where https://youtu.be/4Tnbf44NjXo?t=370

[dusky cobalt]

You forgot to Get Material before your vector, did you not read my response?

[dry scarab]

i did but i dont understand cos im very new 😄

[maiden wadi]

There are also getters that make that easier.

[dry scarab]

is this seapret code? cos he dosnt have that in this code

so u want me to add it before this

[maiden wadi]

6:25

[random pulsar]

like this?

[remote shard]

Just wanted to ask for a quick second: Would it be preferable to make a 'On Death' function a custom event, or an action input? Need to know since I'm not too sure on which is preferable in this situation

[dry scarab]

what about it

i have all code he has other than widget

[dusky cobalt]

Event probably

[remote shard]

Alright, I'll do that

[dry scarab]

like this?

[dusky cobalt]

yea try it

[dry scarab]

nope

i did plug the forgotten pin

[dusky cobalt]

what are you setting as color?

[dry scarab]

😛

[faint pasture]

no, return a boolean

return false if any are not successful, true if the loop completes

[dry scarab]

i think this is the issue?

[dusky cobalt]

@dry scarab this value, what is inside variable?

what are you connecting here

and what is default value of that variable that you are connecting

[random pulsar]

?

[faint pasture]

If it fails, return not successful

if the loop completes, return successful

do you understand what I'm describing?

[dusky cobalt]

Create new Variable, search for Color (it's type of variable), Compile blueprint, go to default value and pick color, Get variable connect it with the Value.

[faint pasture]

Enter function -> loop body -> did this one fail? -> yes -> the whole thing failed
-> loop completed -> the whole thing succeeded

[lofty rapids]

are you looking for something like this ?

use local variable

so it resets each time it runs

[dry scarab]

sorry where

[dusky cobalt]

Value

hold ctrl and drag onto value

[dry scarab]

wont this get rid of the random color?

on enter

[faint pasture]

you don't need local variables or anything

it's literally this simple

[dusky cobalt]

why would it get random color, try it, if everything is well conected maybe it will work

[faint pasture]

Enter -> loop body -> did this one fail? -> return false
-> loop finished -> return true

return bails out

if you hit the return false the loop will not continue

[dry scarab]

so its default m _clor now its, ill try a diff color lol

[wise ravine]

Just to clarify, this is how to make a game state right?

[paper smelt]

How do i do something only if a specific actor is hiting something

[faint pasture]

Which actor and how do you know?

is the actor of a certain type? Is a it a specific set instance of that type?

[paper smelt]

My custom actor

[dry scarab]

nope that's not workign either,im in voice chat streaming if u wanna watch

[paper smelt]

its just actor

[random pulsar]

oh shoot

[faint pasture]

Cast to see if a thing is an instance of another thing

[wise ravine]

Through a box collision and a cast node most likely

[random pulsar]

i dont have local variables

[faint pasture]

Hit -> cast to YourCustomActorClass -> ??? -> profit

[random pulsar]

4.27 doesnt have them?i thought it has

[dry scarab]

im on vc if u wanna watch stream

[faint pasture]

It's that simple

[paper smelt]

Well

That didnt work

😂😂

There

[random pulsar]

yeah made it

[faint pasture]

yup so you know if OtherActor is AN axe

[paper smelt]

with a == node?

[faint pasture]

why branching

The test is if the other thing is an axe, right?

[paper smelt]

If it is an axe do something if not then dont

Its a VR game so im just making sure the axe is the thing hitting the tree

[lofty rapids]

so if the cast succeeds then you know it's an axe right ?

and if it fails then its not

[paper smelt]

It should but idk how to make sure it is

[random pulsar]

wow

magic

its working

[lofty rapids]

if it succeeds then it is, as long as your casting to that bp

[paper smelt]

What do i put in red pin though?

[random pulsar]

thanks for everyone who helped @lofty rapids @faint pasture

[lofty rapids]

in the branch ?

[paper smelt]

Yeah

[lofty rapids]

you don't need a branch

[paper smelt]

Really?

[lofty rapids]

if the cast succeeds or fails can be your branch

[sharp python]

Hmm... I successfully made a spline and spline mesh (chain) at runtime. So far so good, but I want to move the end points of the chain around during gameplay and have the spline mesh adapt to it, and apparently the recommended way is to destroy and recreate the spline mesh every frame??! This can't be right, can it?

😦

[wise ravine]

I dont understand why I can have a box collision component when I cant drop a Game State in a level

[paper smelt]

Ohhhhhhh Im slow sometimes thanks lol

[dusky cobalt]

hold ctrl, take mesh and connect it to Get Material

now it will work, sorry

[sharp python]

You can add actor components to a game state, which is pretty handy. The collision component is one of them. 🙂

[dry scarab]

why is my cicon different

his is thi sone

[sharp python]

Corporate wants you to find the difference between these two pictures

[dusky cobalt]

It's the same

[dry scarab]

lol

other than the blue

😛

[wise ravine]

Yes, but how do I utalize the collision component if I cant put the actual game state in a level

[dusky cobalt]

you have such a mess in your blueprint, no wonder you get lost what you doing

[sharp python]

You don't

[dusky cobalt]

you didnt have something connected and that is why it didnt work

[wise ravine]

so how is a box collision supposed to be used in this case?

[dry scarab]

nah

from what his code was i def had all conneted

urs im workign on still

[wise ravine]

why is using the level blueprint 'bad' again?

[stoic ledge]

its not good to put stuff where it doesnt belong?

[dry scarab]

this is how it set the color

[wise ravine]

But why doesn't stuff belong in the lvl blueprint?

[eternal spruce]

Hi there! I'm currently using the Collab Viewer template to do a test on some VR and Desktop working together. Everything is working as it should but when I press the VR button it takes me to the player start but like way above where it is on the level (high in the air). I've tried teleporting the player pawn back down to the start location but cannot get it to work. Any solution you may have?

[stoic ledge]

scope and design

[stoic ledge]

things that are part of the level should be in the level code.

[dusky cobalt]

change location of the Playe Start in the viewport of the game?

[wise ravine]

okay i guess

[dawn gazelle]

Code put into a level blueprint cannot be reused. Almost everything you make in a video game could potentially be reused in some way. Even the things that you'd think would be great to have the level blueprint do could probably be better handled by an actor.

[stoic ledge]

@wise ravine i read above, what objects are colliding?

[eternal spruce]

I have and it spawns correctly but when I try launching in the VR view is when it teleports me say 30 feet into the air.

[trim matrix]

dropping a game state in the level? wut

[stoic ledge]

@wise ravine i suspect the object colliding should also handle the collision.

[wise ravine]

I know it's not possible, I just dont understand why a box collision component would be needed in a game state if the actor can't be placed into the level

[trim matrix]

not sure what you mean by this

an actor can be placed into a level, but not the game state

[wise ravine]

Basically, what is the purpose of a box collision in a game state?

[wise ravine]

Yes

[wise ravine]

The player and the hitbox

[dawn gazelle]

There is none. The only reason you can add it, is because it is an "Actor" blueprint which accepts scene and actor components.

[dry scarab]

still nothing haha

[dusky cobalt]

You sure you using the same node?

[dusky cobalt]

check again, i recommend you to really put these nodes in nice configuration because its a mess

[wise ravine]

That's strange. Anyway, how do I get a game state to communicate with an overlap collider?

[stoic ledge]

for what reason ;D

[dry scarab]

i do have a plugin for it but cant rember shortcuts anymore

[stoic ledge]

an interface?

[faint pasture]

Maybe explain what you're actually trying to do

the thing with the overlap collider can talk to gamestate, sure

or the gamestate can bind some event to the collider's OnOverlap dispatcher

[dusky cobalt]

@dry scarab 1more thing
Click on mesh of your Cube
On the right go to Material
Click 2 times on material, turn it on
and now do this:

[trim matrix]

no spoonfeeding

[dusky cobalt]

search for Vector Parameter

instead of holding 3

name it color

now it will work i can let you cut my hand

[wise ravine]

#blueprint message I explain it in this message. I already got a very useful answer before, but I think I might be misinterpreting it tho or I dont fully understand how to execute the advice I was given..

[dusky cobalt]

it's this node which is wrong

[toxic copper]

im trying to identify the moment my jump has reached the apex so i can change an "is jumping" boolean to false. as I was writing out a couple of different versions (get velocity and Z < 0, vs event "On Reached Jump Apex") to ask you all for pros/cons of each, I noticed a "Notify Apex" tickbox, which mentions an event notifyJumpApex() to controller.

1. how can i access this event notifyJumpApex? not finding it controller blueprint
2. any pros/cons between either of these 3 apparent methods?

[dry scarab]

get rid of go back to old ?

[dusky cobalt]

You choose (cube) when you call it, it's not needed, call clear function

[maiden wadi]

Anim Blueprint?

[trim matrix]

mmh I think I know the game you are trying to do, just forgot the name tho

[toxic copper]

no just regular playercontroller blueprint

[maiden wadi]

What do you need jumping in the playercontroller for?

[dusky cobalt]

just connect the color to the value that i gave u

[toxic copper]

thats where i built the jump logic. its also where im setting variables and calling animation state function

err where i put all my input actions logic

[stoic ledge]

apex function would be more related to the anim

[dusky cobalt]

@dry scarab holy shit bro you are insane, i swear

CHECK THIS 3 TIMES you have wrong connections

you didnt connect material to the return value of create dynamic material

and i swear if you made these nodes be nice next to each other it would be 500 times better for u

[maiden wadi]

Should mostly all be in your character. But what do you need to know the IsJumping for specifically?

[dusky cobalt]

@dry scarab

[toxic copper]

so its for a few pieces of functionality. I've yet to use animation blueprints so not sure if ultimately better there but

[dry scarab]

it dosnt like me lol

[toxic copper]

Essentially I want "isFalling" to be a bit more specific, as it considers jumping the same as falling. so im building an isJumping boolean so that when I call an "update animation" function, it will set flipbook to my jumping flipbook.

however I want is falling (and isjumping=false) to set a falling flipbook. these same two scenarios are also how i was planning on implementing my platform logic

so that when falling (but not jumping), my character collides with platforms, but otherwise overlaps if jumping.. which i suppose could just be simplified to "is jumping = false", but for that i still need to have "isJumping" set to false as soon as upwards velocity stops

[wise ravine]

Exit 8?

[trim matrix]

yes lol

[dusky cobalt]

Getmaterial is wrongly connected

[dawn gazelle]

So to do what I was suggesting, you'd need to use an actor that contains the colliders.
You can either have them directly call to the gamestate and have the gamestate do something, or as Adriel said, you could have the gamestate look for those actors and then bind to their overlap events. You're likely better off having them call to the gamestate themselves as you'd probably be spawning them throughout the runtime of your game.

[prisma crag]

(this is all one line)

For some reason, my camera isn't being set to Camera_Top_Down even though I've set it up for it to do so. Is the blueprint wrong?

[dusky cobalt]

@dry scarab

Get Material first node

Return Value to Target

not to source material

[wise ravine]

That makes a lot more sense to me

[maiden wadi]

Gotcha. The character has an event called OnJumped. You can bind to OnReachedJumpApex there and set jumping to true and set it to false in the event you bind.

[dusky cobalt]

@dry scarab you still used wrong Create Dynamic Material Node 😄 idk why you call Primitive Component

i think its ok this time

connect it

[maiden wadi]

You use too many nodes.

[dusky cobalt]

noo it was good one and you deleted it

good

[trim matrix]

would the game mode be better for these stuff?

[faint pasture]

No, just actors in the world

[toxic copper]

like so?

[trim matrix]

he said in the game state

[dawn gazelle]

Doesn't really matter in this style of game.

[maiden wadi]

Yes but also set IsJumping to true before or after the bind.

[wise ravine]

Would it matter if I used to BP_train to communicate with the gamestate? Because I believe that much is possible, tho correct me if I am wrong.

[trim matrix]

true but it sounds wrong

[faint pasture]

When the train hits the station, the station can tell the GameState or GameMode that the train reached it and the gamestate or gamemode can do something in response

Start with:
Station:
On overlap -> cast thing to train or otherwise detect that it's the train -> get gamemode -> cast to YourGameMode -> do something

[wise ravine]

Which is better in this situation, GameState or GameMode?

[faint pasture]

eh doesn't really matter, it's a matter of taste. Many people like to put logic in GameMode and state in GameState

[still breach]

QQ but doesn't find the answer anywhere, is there a way I can force a call to parent event for my Event Destruct?

[maiden wadi]

Right click on it

[dry scarab]

any way i can give u the project hahaha?

[still breach]

Geez, I knew it was something stupid. Thanks

[dry scarab]

i cant guve u assets tho

i paid for them so there under leincence

[trim matrix]

can we see them ? I'm curious lol

[maiden wadi]

😄 All good. Would be really nice for some sort of small button on the node to put that in.

[stoic ledge]

@toxic copper i donno ;D in your method id think that up or down velocities would work fine, just a check on a int sign right?

if + / -

[dusky cobalt]

idk but im tired

get easier tutorial and learn basics

[maiden wadi]

You just need to restart. You're struggling with an extremely basic concept and you need to run through the tutorial again until you understand why.

[wise ravine]

Can't I do this logic in the train blueprint? because I have a timeline movin the train, so wouldn't I be able to execute that code after the timeline finishes?

[dry scarab]

the issue is it wasn really a tutorial

it was more this does this , he never did the full thing from scrath so i dunno if im missing things uses material etc etc

all its suppsoe to do

is on overlap make 3 random colors and aplly to cube mesh lol

and it dosnt work

[maiden wadi]

The things you're struggling with are all in the screen at 6:25 as I stated before.

[trim matrix]

learn about materials

[dry scarab]

this bit

[trim matrix]

doing it on begin play?

[maiden wadi]

Yes. This creates a new material instance with the M_Color on that StaticMesh

Then on overlap it sets a parameter in that dynamic material.

[dry scarab]

yes and i created a m_color material

[trim matrix]

quick qeustion:
Is it better to do in the construction script?

[maiden wadi]

Not unless you need it at editor time.

[toxic copper]

doesn't seem to be triggering

[trim matrix]

3d stuff seems great

[maiden wadi]

With prints or debug points, you don't get anything from those events?

[toxic copper]

yeah pretty much, i think itd work fine, just thought if there was an internal way to check for the apex, would be cleaner to use that instead

[stoic ledge]

@toxic copper as far as i can tell theres nothing firing that custom event, to state its at the apex?

[toxic copper]

i tried a print and got nothing

[dry scarab]

https://syntystore.com/en-gb

[dry scarab]

ok i got that ish

so what is failing ::D

ill start from 0 again

[maiden wadi]

Did you test that the overlap is running?

[dry scarab]

yes

[maiden wadi]

What about the jumped event?

[toxic copper]

so to be honest, ive never used delegations or binds before, so im not entirely sure how it works. it seems like Jumping ties the defined event to that specific jump, but no idea

jumped event works fine

[maiden wadi]

What do you currently have atm code wise?

[dusky cobalt]

@dry scarab watch video again and @maiden wadi good luck xD

[wise ravine]

Why cant I just promote the variable here, do I have to cast to the game state to get a reference of it?
