blueprint

[brazen pike]

It's not going to be created at the start of the game, so you need to find a path to it

which is why I suggested referencing the actor which creates the widget

[zealous fog]

This might be a silly idea and I'm no professional, but couldn't you save the ismixed on the player character

[thorny rover]

Hello! I have a question about Navigation Data Object referece.
I have 2 separate navmeshes (navmeshbounds) on different sublevels. I want player to switch between them (and place player on the correct navmesh afer switch).
I want to use "Get random reachable point in radius"
But seems that Nav Data is not compatible with Nav Mesh bounds, i get error:
"nav mesh bounds volume object reference is not compatible with navigation data object reference"

Is it somehow possible to convert navmesh bounds volume into Navigation data reference?

[brazen pike]

That assumes there will only ever be one button. If there are multiple then it will be "is mixed" true for all of them if its done in the playercharacter.

[lusty wraith]

ok, I did what you said, referenced the pc_int_wb in the pc_bp (which is where the WB is created) but it still says none in the default value. Also now, im not sure how to call the boolean

[brazen pike]

If its done in the individual BPs, then it can check for a specific button

Can you show slightly more of the PC_BP

[zealous fog]

Yeah that's true

[lusty wraith]

sure

[zealous fog]

Difficult to say what's the best option without knowing what system you're trying to make and what the gameplay context is

[brazen pike]

So you have the same issue. What you need to do is drag out the variable onto the graph and select "set"

then you can tell the variable what it should reference

and the input of the "set" node should be the output of the "Create widget"

[lusty wraith]

ok, so like this

[brazen pike]

Yes

[lusty wraith]

thank you, i'll see if this works

[brazen pike]

it won't work unless you have set the PC variable properly

You can now find the widget from the PC, but you also need to be able to find the PC from the vending machine

[zealous fog]

Interface could be a good option there

[brazen pike]

I'm not too sure about that, my best guess would be an event dispatcher but then again still need to reference

[undone surge]

this is a parent class, what node do i use to get a specific chilld class from this

[brazen pike]

Do you know how to set an instance editable variable from the viewport?

[brazen pike]

Cast to (Child)

[undone surge]

thank you

@brazen pike what does convert to pure cast do

[zealous fog]

Why not? When you perform the action that needs to check the ismixed bool you can get player character, use the interface to get the reference and then get the bool

[lusty wraith]

unfortunately no.

[brazen pike]

Just that you don't need to put it onto the execution line, and it will assume that it is valid rather than giving you an success and fail exec. If it could ever fail but a branch into the boolean output it gives

[undone surge]

ahh so basically it will run whether condition is valid or not

and if it isnt it will error

[brazen pike]

yeah

[undone surge]

ok thanks

[brazen pike]

Well I'm sure it COULD be done that way. I'm just not sure how since you need a reference to the pc

[lusty wraith]

i think this is it actually?

[brazen pike]

yes that's it

[lusty wraith]

ok, ima see if i can figure this out now

[brazen pike]

Now get the PC variable, then get the widget variable from that, and finally get the boolean from that

[brazen pike]

What would you use as an input?

(that is one of my interfaces)

as an example

if you didn't already have a reference

[lusty wraith]

omg, thank you so much, it works ❤️ ❤️

@zealous fog thank you also for your suggestions

[brazen pike]

I've just looked into it, and a slightly better way of doing it would be to use an event dispatcher. But I'm not telling you to change it, just letting you know what to google if you would like to slightly improve it

[lusty wraith]

I did wonder that to begin with, i tried to do it but couldnt get my head round it. Why would it be better? is it less expensive?

[brazen pike]

I believe so, but I couldn't tell you why

I think memory usage, might need someone more experienced to confirm though

[lusty wraith]

I will have to learn them eventually i guess

[zealous fog]

Get player character

[brazen pike]

The PC isn't the player character though

Its just an actor

[lusty wraith]

🤔

[zealous fog]

Oh lol

The abbreviation threw me off

[brazen pike]

Yeah, add on top of that the widget is called PC_Interface

[undone surge]

@brazen pike is this blueprint correct ? i have a parent weapon class for which i created different child classes to keep it organized but i have my custom event(Fire) in the child so i did casting but this isnt working. did i cast it right ?

it only works if i put my custom event in the parent class and it uses variables only from parent class then

[brazen pike]

what does that code look like

I mean in the character

[undone surge]

this is inside main character blueprint

event graph

this is child

[brazen pike]

yes but I assume to get it to work with the parent, you are no longer casting to the child

[undone surge]

i need it to work with the child class but it wont work

so i was wondering if i did casting right

[brazen pike]

It looks fine to me. Are you getting an error?

[undone surge]

no it just doesnt fire the gun

[brazen pike]

Where does the execution fail, at the cast?

[undone surge]

first it was firing but it was using parent variables which i didnt want so i made fire event inside child class

it wont go past cast

the red line thing

when i play

it stops at cast and wont go into the custom event

[urban haven]

Hi all, Variant manager question: Can I duplicate objects/Blueprints using the variant manager? Like I would want 2 or 3 cars instead of 1. Is this possible?

I think it is similar to regular spawning an object?

[thin panther]

Whats in the weapon variable

[undone surge]

its a class

parent

[thin panther]

If its a class then the cast will fail

You need to give it an object

[undone surge]

Ahh

how would i do that

[thin panther]

When you spawn and attach the weapon, set its the variable to its return value

You need to tell the cast which specific instance of the weapon you mean

So you need to store the reaukt of the spawn

[peak summit]

why is it standard practice to move your mesh down to align with a capsule collider instead of bring the collider up? "Show floor" is half way inside the capsule in preview.

[trim matrix]

Hey Guys, i need to scatter loads of coins in a transparent container... how would you do that? i tried physics but can't freeze the position

[undone surge]

i see

[thin panther]

Because you cant move a root

[peak summit]

works for me ;P

[thin panther]

Typically your collision will be the root

[peak summit]

good note..

lol

[worthy carbon]

When i try to attach my backpack to the character it doesn't attach and it gives me this error

[undone surge]

@thin panther i would do that here right after the final node ?

[keen schooner]

I could be misinterpreting, but should you even need to cast to the parent class? I use something similar with my item pickup system, in that the base item class has an Interact event, but Backpacks function differently when picked up than other items. I used Override on the backpack blueprint's Interact event, wrote what I needed in there, and it defaults to that overridden event instead of the parent class's Interact event. No casting needed.

[thin panther]

Youve already done it?

Does ak 74u inherit from bp ak

[undone surge]

ohhhhhhhhhhhhhhhhhhhhh

it

doesnt

xD

let me see

[thin panther]

You need either your master weapon bp, or your specific weapon

[undone surge]

yes

it works now

thank you so much

[thin panther]

Np

[trim matrix]

guys, i would like to save the position of some componentActors after a simulation, do you know if it's possible to do so in a BP?

[sly forge]

Hello, is it no longer possible to change pins order in blueprint functions in unreal engine 5?

[odd ember]

what do you mean by component actors?

[odd ember]

it probably is but they have probably found a new way to make it more obscure

[trim matrix]

Hey so im working right now on a modification of a Game and i need a way to get a distance from my pawn to the closest player pawn.
Somehow the code doesnt show the distance to the closest player.
I hope someone can help me.
UE Version 4.21(I know its old).

[odd ember]

if you just want a straight distance, there are nodes for that. I'm not sure what you're doing with that segment node. I assume that's custom made

[real notch]

Not too familiar with BPs, is there a dummy object I can place in a BP to just use as a way to get a vector3 location as a spawn location for construct/scripting ? I see arrow?

[sonic moss]

I've used arrows and billboards in personal projects.

[worthy carbon]

Hi everyone! does someone knows how i can attach items to the character if its in the inventory?

[keen shard]

can anyone theorize as to why this works:

and this doesn't work (doesn't fire)

[odd ember]

almost certainly some multiplayer server client issue

[keen shard]

it's all in one instance. no replication

like, this is the player running as server.

[maiden wadi]

Seems like it's called too soon. The binding allows it to call later?

[keen shard]

basically, there is a bunch of server config that happens, and this other actor needs to know when the gameinstance is done doing that configuration when you're host

the actor waiting for this to be called is an actor in the level.

the order of operations is this. InitPawn spawns -> configures player, tells game instance to configure server -> Game instance configures server -> calls Server Ready

[odd ember]

which blueprint is this in

[keen shard]

two important actors on the level. the InitPawn and GameAutomator (that's waiting for the Server Ready to be called).

GameAutomator is in the level

so I thought, the GameAutomator have it's begin play happen AFTER Server Ready was called, totally possible.

so I added a 1 sec delay to the Server Ready call in GameInstance to make sure.

still no go

so then i did bind on ServerReady (in the GameAutomator actor), removing all delays, and it worked

[maiden wadi]

What is calling the Server Ready?

[keen shard]

GameInstance

[maiden wadi]

What event?

[keen shard]

this is in game instance

if i bind to the event* in InitPawn or GameAutomator (which exist on the level) then they are called properly.

but if i use the green button thing

it doesn't fire

[tranquil elm]

is their a way to pass props or txt and make them into script ?

[keen shard]

like i'm waiting for someone to tell me that you just can't do the green button event thing with specifically the GameInstance

and if that's the case, should i just never use this green button feature?

[maiden wadi]

What exactly is the GameInstance ref you have there? That's not usual to be binding things like that. Usually that green button is used for binding children's delegates. Like using a Button inside of a UserWidget.

Chances are the binding is the problem. Whatever that ref is, it might not be valid at binding time.

[keen shard]

OHHH i think i got it

yeah, i'm doing this

so when i do the green button bind, it's binding to an empty reference

[maiden wadi]

Yeah. That'd be way too late for that delegate. You'd need to bind that yourself after that Beginplay set.

[keen shard]

because the delegate is bound on construction of the actor, not on begin play

begin play happens after

[odd ember]

don't think delegates can be bound in the construction script

[keen shard]

i mean, just whatever the default behavior is, the green button event node is connected to the initial GameInstance var, which is empty

until begin play, where I set it

[maiden wadi]

On a side note. I encourage not bothering with ref keeping so much. It's a waste of effort, and can in some cases cause memory garbage collection problems. GameInstance is global and very fast to get, and always valid.

[echo salmon]

Hello guys, i was wondering when the checkbox is checked it doesnt play the sound i have assigned ?

[keen shard]

this green button binds to the empty reference. because it's empty before "begin play" and this green button binds the event before begin play

[ionic raft]

hello, sorry to interrupt, but is it possible to set fullscreen to different resolutions? so like have the game be in fullscreen mode but have a low resolution, for example. I'm using the game user settings and the "Set fullscreen mode" and "Set screen resolution" and "apply settings" nodes. Whenever I try to set the resolution lower than the desktop resolution, instead of keeping the game fullscreen, it makes the window go smaller and fill the top left corner of the screen. Also, when I switch to windowed and back to fullscreen then change the resolution to a larger one, it fills the space with black. Am I just trying to do something impossible?

[tawdry mural]

you can "play sound2d" in your function

[ionic raft]

i think check sound only plays specifically when you click on it

[echo salmon]

@ionic raft i guess yes

[maiden wadi]

Don't test stuff like this in PIE. Try keeping graphic setting tests like this to Standalone. PIE will react oddly to a lot of settings.

[keen shard]

Thanks @maiden wadi . It's good to know why this is happening and not that it's a weird bug. this will be huge in helping me avoid similar issues in the future. as far as using these references, i use them so I don't have to cast to my custom class all the time. which game make the code super verbose. the reference should die when the actor dies, so i'm not sure if that is too much of an issue in this case. but i wouldn't consider myself a garbage collection expert

[neon orbit]

Hey ya'll! I’m very new to UE and am looking for help with some VR work I’m doing with Blueprints in 4.27. I want to utilize morph targets on a hand skeletal mesh I made that I’ve assigned to the Oculus Hand Component. Any suggestions for how to get this working?

[maiden wadi]

Make a static BP Library function that returns your casted game instance. Much better to create framework for your projects.

[ionic raft]

thank you... yup it works in standalone.

[keen shard]

good advice, appreciated

[proper dagger]

hi! when I create a widget and add it to the viewport with a trigger box it makes my character character move forward on it's own. Stop Movement Immediately doesn't work.

[trim matrix]

hey guys

does anybody know how I could make a timer that activates when the line trace hits a target?

and when the timer hits 3 secondes

it will activate the custom event (stunned)

[proper dagger]

add a delay of 3 seconds?

[trim matrix]

Wow its that easy?

[red fossil]

Anyone know why this is not working? I'm trying to get my character to pitch and have it replicate to other players. I was using "set actor rotation" before which worked but apparently I'm supposed to use "set control rotation". But no luck so far

I need it to change the control rotation depending on the camera angle

[maiden wadi]

Depends on what you want in the end. If you want to line trace once and stun it after 3 seconds regardless of whatever else may happen, then yes. Otherwise you need a different approach.

[maiden wadi]

You set control rotation locally on the owning client. Control rotation is a user's desired look direction. Depending on your use case, you have to use GetBaseAimRotation, or create your own implementations from replicated states to do what you want. GetBaseAimRotation only uses Replicated Pitch. It uses the pawn's world yaw and replicated float as pitch. Your movement component, animbp or character tick would still need to handle visuals locally in every client from these inferred or replicated states to get the kind of view you're after.

[trim matrix]

I want the animation to activate when the player is holding right click for 3 seconds

[red fossil]

The setup I have is not working at all even when playing as listen server

Semi sure you can just set them to something very high and low.

[small halo]

trying doing that but then player starts loooking backwards

[trim matrix]

@maiden wadi can you help me bro pls

[red fossil]

I got it I think? This works and replicates perfectly

instead of set control rotation

[loud badge]

Guys quick question, can I set a property on my gamemode blueprint class through the editor? (child from c++ gamemode which has a Uproperty editanywhere), can't find it .. I might be doing something wrong.

[maiden wadi]

Sounds like a tick gate. Right click opens, releasing right click closes. On tick trace. Hit Target, Set float to current game time, set actor ref to hit actor. If any trace misses, set float to -1, and the hit actor to null. If hitting the set actor ref you have saved and it's valid, then check if the current game time is > SavedFloat + 3.0

[fluid lagoon]

Hey guys! Im trying to put a cap on the health at 0 when the player reaches that, the first image shows them all being set to 0, and the other is the test damager. The health still goes below 0 anyhow, Just wondering if anyone had an idea?

I feel like it might be how Im minusing the health?

[trim matrix]

U mean hit target right?

[true lake]

Hello, does anyone know why on the top down template the character doesn't go right on where we click ? It's 50 units aside of the clicked point.

[fluid lagoon]

Instead of checking to see if its 0, should I use this instead and set it as the health?

[maiden wadi]

Movement acceptance radius.

[tawdry mural]

the value wont go below 0 if you use clamp

[maiden wadi]

Also. Clamp is Fine, but Max is quicker, and a smaller node.

[true lake]

And where do you find this value please ?

[fluid lagoon]

Nice, should I plug this into a set statement for the variable in my tick event?

[tawdry mural]

you can use it anytime the value changes, it dont need to be at tick

[maiden wadi]

I'm not sure. I think that template uses SimpleMove. Not sure how to affect that. Normally you specify it on the AIMoveTo nodes.

Would probably just do some prediction math and place the point slightly past the cursor from the pawn.

[true lake]

Thank you very much for your answer ! I will look for more infos

[trim matrix]

im too visual bro

can you show me an example

[undone surge]

what nodes would i use to change rotation of camera

[loud badge]

stuck here :x its possible to have custom properties on a gamemode? beside the default ones?

[dusk cave]

Hey yall I'm trying to figure out how to use the for loop. For some reason, this only does what I want once.

[tawdry mural]

because delay

for loop touches delay 9 times but it only shoots further once after 2 sec

[dusk cave]

im confused. what do you mean it only shoots further once

[tawdry mural]

for loop shoot instantly 10 times

[dusk cave]

oh

[tawdry mural]

it doesnt wait for delay

[dusk cave]

so if I wanted to make something change materials every 2 seconds, i shouldnt use the for loop?

[tawdry mural]

no but you can use timer by event/function

[trim matrix]

@maiden wadi

I tried this for a test to display the time that I hold down right click but it doesnt work

No time display

[plush ridge]

Any way to change the default rotation of an animation that has root motion enabled? It seems to use the same rotation no matter what I do. I tried changing the root's rotation on frame 1 and setting a keyframe there but no luck

[tawdry mural]

import rotation should work

[plush ridge]

It makes no difference, sadly ;/

Only if root motion is disabled

[worthy fern]

Does anyone know how to modify the post process properties of a scene capture component in order to dim it?

[fallen glade]

Is it possible to sample a curve from the editor like this without creating a variable for it?

[misty tulip]

Hey everyone I'm following a tutorial for creating an inventory system. It's from Ryan Laley on youtube. Everything is working great. But the way he has it set up is one item that the mesh gets set when the item is created. You set this through exposed variables. I have this all set up.

But my issue is that I cannot see the items when setting up the map. Only when I play the game. Is there a way to show the selected mesh in the editor without the need to play. Then I could see where I'm placing an object. This is how I see the items in the editor now.

[desert juniper]

BeginPlay only runs when the game actually plays, hence why you can't see them in the editor

you can separate the logic to a function or event, and then just call that in both BeginPlay, and in the construction script if you'd like

[misty tulip]

That would require cpp right?

[desert juniper]

no

take a screenshot of your entire editor

I meant the bluepint you had that logic on, but found a screenshot on google

that's the construction script tab.

[misty tulip]

Ok I see that

[desert juniper]

Any logic you do on construct will run as soon as any values are modified in the editor

to make it simple for now, just copy/paste your code from the BeginPlay, into the construction script

[misty tulip]

Oh wow

Ok but I should keep the same code in begin play?

Oh I understand. Make all my code a function then place in both so changes apply to both

[desert juniper]

best practice is to separate it out to a custom event, or a function, then you just call that event/function in both places

yup. you got it

[misty tulip]

Wow the construction script is great to know

Thanks for your help!

[desert juniper]

🙂 no problem!

[scarlet arrow]

Does anyone knows how to stop a function?
I have a health regeneration going on as a function on Event Tick and i'm trying to add a cooldown to that HP regen every time my character receives damage

it should be like this

If character receives damage, health regen stops for 5 seconds, after 5 seconds health regen starts again

[dusk cave]

i'm gonna guess you'll need to use a branch and some bool variables

[scarlet arrow]

i did that already and it's not working

[dusk cave]

shouldn't my branch be looping if it's in Event Tick? I want whatever is happening in false to repeat until true

[faint pasture]

On Tick

Health = Health + DeltaSeconds * Regen * bCanRegen

On Hit

bCanRegen = false
set retriggerable delay or time to set it back to true

[faint pasture]

Bruh if you're putting a delay in event tick then you're fucking up. What are you trying to do here?

[dusk cave]

im trying to make something look like it's flickering

until the player does something to stop it

[faint pasture]

So do you want to flicker by swapping materials or changing a parameter on the material?

Typically it's done with a parameter

[dusk cave]

oh i haven't figured out how to change the parameter through blueprints

[faint pasture]

But you can do what you have there with a delay or timer

Or a looping timeline if you want to parametrize it

Try this, make an event StartFlicker and event StopFlicker, drag in a Gate and your material setting nodes and a delay, and you'll have all the stuff you need to make it happen

Startflicker -> open gate -> enter gate -> set material -> delay -> set material -> delay -> back to enter gate
StopFlicker -> close gate -> set material

[dusk cave]

okay gonna try to set it up

[dusk cave]

im not understanding the gate node. so start flicker connects to open gate, then enter?

[white elbow]

How do you make a surface show the another camera's view? I'd like to make a scope like that (from Unturned)

[faint pasture]

Yes use a sequence to first open the gate then enter

gate is just like waht it says, its a gate. you enter, and you either proceed or don't depending on if the gate is open or closed.

[faint pasture]

Render target

[white elbow]

A good start, thank you

[dusk cave]

like this?

[faint pasture]

@white elbowSpecifically, put a camera component right in front of the scope with a narrow square field of view (like 5 degrees or so), and capture it to a render target (forgot the node name). Then use that render target in a material somewhere (prolly at the other end of the scope

[faint pasture]

Yeah, now do the rest and try it

[dusk cave]

I think I'm doing this wrong

[spark steppe]

well, all i can say is that you are doing screenshots wrong

who is supposed to be able to read that?

[faint pasture]

Nah that looks fine, what does it do?

[spark steppe]

start flicker => set flickering material
stop flicker => set not flickering material

[faint pasture]

He doesn't have a flickering material

he's flickering by swapping materials over time

[spark steppe]

then he should make one

[dusk cave]

I need to it to start flickering when the game starts so it's not doing anything atm

[spark steppe]

then call startFlickering from BeginPlay in the same actor

[faint pasture]

BeginPlay -> StartFlicker

[dusk cave]

sorry how do i screenshot these better

oh its working

thanks @faint pasture then all i have to do is call stop flicker wherever I need it?

[faint pasture]

Yes. Start just trying stuff before asking lol. That's how you learn, just yolo and try stuff.

[thin panther]

yup, ask for the help when it doesnt work, not before you've tried

[dusk cave]

i did try a couple of ways and now I know to use a gate node

[faint pasture]

There's 10,000 ways to do this. The takeaway isn't "Use a gate node to make something flicker", the takeaway is that now you know what a gate node does and you can use it in combination with timers or delays to do complex stuff. You could use that exact same setup to make a machine gun

[mild pine]

Hey guys, I've setup the ability to shoot physics objects, but I'm getting warnings when I hit objects that aren't set to movable. Is there a solid way of checking for what actors to apply the force to, other than casting to every single physics object I have? 😅 I guess I should make one parent in that case

https://gyazo.com/b9fbdb6d2e35967107a41653d97a1798

[faint pasture]

There's an IsSimulatingPhysics node

Show what you do when you hit something

[mild pine]

Target is HitComponent

[faint pasture]

Check if hitcomponent is simulating physics before impulse

and you prolly only wanna do all this on the server

[mild pine]

The gun's triggered by the server 🙂

That worked neatly, thank you! Didnt know about that check 🙂

[faint pasture]

@mild pineYou shouldn't need another RPC to do damage. Do it like this
Event Hit -> Authority check -> deal damage -> physics check -> apply impulse

Only the server projectile will pass the authority check to deal the damage and apply the impulse

[mild pine]

Oh, is it not the same if I do the authority check before I spawn the projectile?

[acoustic tundra]

Hi, i've had an issue for some time now but haven't been able to find a fix.
I have a main menu that pops up in a cutscene (made with the sequencer). This all works. However, I'm not sure how to bind an event from the widget bp (play button in this case) to an event in the sequence director (in which I can tell the cutscene to stop playing).

[icy dragon]

Event Dispatchers / Interfaces.

Or alternatively have your GameInstance store reference to the cutscene and go through it

[mild pine]

Hey guys, is there a better method to disable backwards sprinting than setting a bool on W (that could be bypassed by changing input keys, but anyway) and checking if that's true when sprinting? Right now I can initialize my sprint while holding W, and then I can, while sprinting, use S to run backwards. I've read someone say "You should compare the forward vector on you character with the actual direction it is going. Take the dot product of the vectors and see of it's lower than your threshold before setting your maxspeed." - but is this best practice? Would prefer not running this on tick. Getting the axis value and checking if that's -1 (backwards) would've been a nice way to go about it, since that value is already being set per tick for movement, but that also allows me to bypass it by holding sprint & changing secondary input.

Edit: I added a boolean check in Input MoveForward & set a bool that would be run through a check in the sprint code, but that -also- didn't stop me from bypassing by changing input while running. Am I overcomplicating this? 🤔 😆

Moving this slider basically moves the start point along the spline to whatever value you set here. But the most important part for me is it does this in the editor without having to run the game. So its definitely some construction script thing

[ember mortar]

Hey, someone knows why this might be throwing infinite loop exception?

[faint pasture]

Because it's hitting the max loop iteration

What are you trying to do? While loops do NOT operate over several frames if that's what you're trying to do here

The frame that you press that button, that while loop will iterate like 100k times, crap the bed, then throw that error

[ember mortar]

Oh, I am trying to make it that the longer you hold the button down the stronger your throw will be... I just need to add some value like every second to a variable until you release the button. Guess I´ll have to use something else than while loop

[faint pasture]

Try a timeline

play timeline on button press

Or you can store the time when pressed and check the stored time when releaseed

depends on if you need a visual/auditory feedback of the throw strength or not

[zealous fog]

Timer would be another option

But I probably love timers too much I use it for so many things lol

[dire timber]

Hey can anyone help me with adding water, like on an island that goes on forever, that works on a huge open world map?

I tried ue4s water sytem but the map is too big for that

[acoustic tundra]

Tried this. Any clue why the cast to the GameInstance fails?

this is in the GI_Game

[ember mortar]

Yea thank you! This was all I needed, two nodes... no need for any loops and stuff

[zealous fog]

Do you have the right game instance class set

[faint pasture]

Released should do the actual throw after/before stopping

[acoustic tundra]

good point ahah think i forgot

works now, ty <3

[zealous fog]

Ah cheers!

[zealous moth]

@ember mortar why a timeline?? Use a timer and enable on press and do repeatable event in it at interval and stop when released. Timeline makes little sense imo

[ember mortar]

Hmm seems like it is working just like I needed though (Code shown at the end of the vid.)

[faint pasture]

You are calling play montage on update

which happens immediatly

and every frame the key is held down

honestly I'm surprised it's not doing something obviously wrong but it's 100% not working how you want it to. What happens if you just hold the throw key for like 3 seconds?

[ember mortar]

Yes yes, I noticed the montage started playing immediately since he changed the stance a little... it works perfect now after the readjustments you suggested. It should be ok like this right?

[torpid mulch]

How can I check if this is valid or null as a condition? I tried "Is Valid" but I don't really get it :(

[earnest tangle]

Note it's returning an array

So you need to check the array's length

[torpid mulch]

I wanted to return a single component (as it only has one with this tag) but someone told me to get the 0 index as it is the only one it could have on the array

[earnest tangle]

Yep that should work

[torpid mulch]

Does 0 count as an item on the array or it needs to be 1?

[earnest tangle]

Arrays start from index 0, so assuming there is at least one item in the array, this should work

[torpid mulch]

Weirdly I'm receiving this even after verifying the array

[faint pasture]

@torpid mulchWhat are you trying to do?

You might be trying before player pawn exists, idk

[earnest tangle]

^this would be my guess as well

the error you're seeing is from the get player pawn node's return pin, it says the value there is "None", so it can't use the get components node

[torpid mulch]

This is the test I was doing, I'm not very used to the blueprints system yet, but shouldn't the error not exist as the branch verifies if the player exists?

I'm sorry I'm still a bit lost with the flow of the blueprints

[dawn gazelle]

Array Length returns 0 if the array is empty. If your check is >= 0, it'll return true if it's empty, so getting array index 0 will cause an error if the array is empty.

That being said, if your player pawn doesn't exist when this code is called, then it'll error out as you're already seeing.

[torpid mulch]

Oh, my bad, the engine I used before -1 was empty and 0 was an item, that’s why I was trying to get the player on “0” and also verifying for >= 0, it was the same count on both

I’ll fix it right now, tysm for explaining it to me :)

[south pier]

Hello, I created a Niagara system, but was wondering how I could attach that to a line trace to act like a bullet trail

[oblique vigil]

Hello, I am currently working on a project with a light puzzle and I need to make it so completing the light puzzle opens a door. I have everything working, the only part that i don't know how to do is detecting that the puzzle is completed and making that open the door. Any help is apricated

[faint pasture]

define light puzzle

what's the win condition?

[oblique vigil]

its a 3x3 grid of tiles and when u step on one of the tiles it lights up the tiles and the adjacent ones

the win condition is lighting up all the tiles in the grid at the same time

[faint pasture]

Oh ok, well you have some sort of Update function on the puzzle that sets all the new puzzle state, whenever that is called, check if they won (Are all tiles lit up?). If so, call Event Complete or whatever and do the stuff that happens when you complete it.

[oblique vigil]

ya i understand that, but i dont know how to check for them all being lit up and than using that send a signal to the door making it open

[faint pasture]

Do you have a Puzzle Actor or just a bunch of PuzzleTile actors?

is there something that knows about all the tiles?

[oblique vigil]

there is one tile that i duplicated 8 more times

[faint pasture]

But nothing has a reference to all of them? Something has to handle the logic for the puzzle being done

[oblique vigil]

oh ok, how do i do that?

[faint pasture]

is a puzzle gonna be a common thing or is this just a one-off thing?

[oblique vigil]

1 off

[faint pasture]

K then just make a LightPuzzleActor and reimplement the logic in it

that's what I'd do

should be simple

OR

make a LightPuzzleManager actor assuming you already have the lighting up logic done with your seperate actors

have it have an array of all the tiles

[oblique vigil]

ok imma be honest i am very new to unreal so could you give it to me in laymans terms?

[spark steppe]

you make a new actor blueprint, which handles/manages all your tile actors

the manager could also spawn the tile actor to the level

like a manager in a company tells it's employees what to do 😛

[oblique vigil]

ahh ok

thank you very much

[trim matrix]

the branch is connected to Event tick
does anybody know why this is not working
so basically what im trying to do is if I hold down right click and let go its supposed to display on the screen for how long in seconds I was holding down right click
this is just a test to see how I can later implement an action where If I have a line trace on an actor while holding down the right click for 3 seconds it will freeze the AI

[oblique vigil]

i got that working, but now how to i make it so it actually detects when the puzzle is complete (all the tiles lit up)

[spark steppe]

how do the tiles know when to lit up?

or rather, when a tile lit's up, notify the manager about it, the manager then checks if all tiles are lit, and decides if the game was won or not

[oblique vigil]

this is what i got in the tile

[stuck hedge]

When you 'get current level name' while using level streaming, does it return the name of the parent level or does it return the name of the current streaming level you might be standing in?

[spark steppe]

pretty sure it get's the name of the persistent level

[stuck hedge]

Thanks.

[dire timber]

Hey anyone know how to make the ue4 water cover a large land mass?

like not just that small spot

[spark steppe]

the problem is that you can stream multiple levels in the same place if i'm not wrong

so there wouldn't be a reliable way when only returning one string

[stuck hedge]

I suppose that's true. That's fine, I can just do it by index

[rough cedar]

Is it possible to visualize a sequencer triggered event in the editor without running or simulating the game? Like if my camera reaches a certain distance on my spline have it trigger an event and let me see how that’s looking in the viewport. I know it’s a tall order 😩

[spark steppe]

no

[rough cedar]

I figured

[icy dragon]

No. Sequencer events only work in runtime tick, not on editor tick.

[vast kindle]

Anyone know of a clever way to get around the issues of Map variables not being replicable?

[unkempt harbor]

hey folks, i updated to 4.27 recently and the console command t.MaxFPS used to work properly when used in conjunction with Execute Console Command in 4.24.
Now in 4.27 there is no way for the user to change their maxFPS because the console command no longer works if its processed through Execute Console Command. That being said it still works if I use the tilde key as a developer and input the console command manually. Anyone know a workaround?

Oop nevermind, figured it out. I was altering Game User Settings in the same function and Epic added Set Frame Rate Limit between 4.24 and 4.27. Problem solved!

[still rain]

i discopnnected the parent construction script, but when i compile it still call it

anyone help?

[dawn gazelle]

Closest you can kinda do is make a structure array of your key and value type, then populate it with the contents of your map and replicate the array.

[shell heath]

Not sure if this question belongs here so please forgive me if I’m wrong.

I was wondering, if I do a data sheet for a list of my characters. Do I just enter their stats there or would I have to make a stat structure and then attach it to the data sheet?

I’m trying to maximize work efficiency without too much clutter.

[teal gull]

when you create the data table, it asks what struct it will gets its collums from. I have done this for weapon stats

[shell heath]

So should I make a character data sheet that just lists their name?

Then make a separate structure that holds all of their mechanic details (lvl, exp, health, etc.)?

[dawn gazelle]

A data table is read-only at run time so it's not really useful for keeping track of things like level, exp, health, etc. It can be used as a base for initializing characters though if you want to use some data driven design to create your characters rather than using several child classes.

As far as saving the data for later use, you'll want to use a save game object and this is where a structure could come in handy as well, as you could then have a map variable set up with a key for the character, and the value set to that structure, so you can easily save and load their stats.

[shell heath]

Hmmm, I’m still learning UE so what you just said went over my head.
I keep running into videoes where people say to make a structure for stats (which I assume would be just about every stat possible like prestige’s and such) but I guess I don’t know how to make the different characters without a data sheet for the game to know who has what stats.

[stuck plaza]

Is there any way to check where particular even dispatcher/delegate was subsribed to, for example a list of all blueprints?

[icy dragon]

I think those are usually bound at runtime, so except reference viewer, maybe there's no way to tell in editor

[urban haven]

How would you make a row of BPs?

[icy dragon]

wdym by row of BPs?
Is it bunch of actors stacked in a row in the map?

[urban haven]

I have a variant manager which controls parts of a BP, but simple duplicating the BP does not update the changes that the variant manager makes... So I need a way to make a row of BPs, but they need to follow the original BP... If that makes sense @icy dragon

[tribal stream]

How do I do events based on an integer's digit?
Or how do I select and print a digit of an integer?

like:
13
I want to print 1 (first digit)
or print 3 (second digit)

[thin panther]

Convert it to a string

And print string

Then you can just access string[0] or string[1]

[tribal stream]

How do I access it?

I am using BP (obviously), is it possible there?

[tribal stream]

some pointers would be appreciated.

Tried to google stuff, but came out empty handed.

[thin panther]

Jeez ya gave me a whole 3 mins

But use the get substring

Digit 1 is index 0

Digit 2 is index 1

Length will be one

Damn i think this is one of the first ive seen that c++ makes easier

[fiery knoll]

Is there a way to go 'into' a map check error to get more info?
I marked a BP as deprecated, and got a map check error which indicates the BP is still present in a map (I think).
However reference viewer shows no references from any maps.
Would be handy to see which map triggered the map check warning.

[fiery knoll]

You could also do a 'Find in blueprints' search with the name of the event.

[trim matrix]

idunno why my projectile tends to fall through the floor randomly at low framerates. Any ideas?

[urban haven]

I have an idea: If I have a parentclass and change that through Variantmanager, will the childern of that class adapt those variant change?

[mellow folio]

is it using the UE projectile component?

[thin panther]

What exactly are you trying to do

[urban haven]

I have a variant manager which controls parts of a BP, but simple duplicating the BP does not update the changes that the variant manager makes... So I need a way to make a row of BPs, but they need to follow the original BP... If that makes sense

[trim matrix]

No

I've been having to use addforce it give it its own gravity cause I need it to hit the floor sooner than the player

[mellow folio]

then post pics of the code

[thin panther]

If you copy paste a bp it should definitely be the same

[trim matrix]

oh yeah lol

[urban haven]

That is correct, but not when using a variant manager... The copies remain in the same state as you copied them...

Can I force them to update somehow?

[thin panther]

When you update tje manager just get all of the bps and update them

[trim matrix]

The big cylinder simulates physics but sometimes it just doesn't work, even at 60fps + it can still fail, rarely but it happends

[mellow folio]

You might need to turn this on on the Root Component

[fiery knoll]

I think your casting does not succeed (don't see the print happening when the cillinder falls throught the floor)

[trim matrix]

No the casting does work I've checked

it prints landed succesfully every time

[trim matrix]

I'll try this

that seemed to work thank God. 💀 only thing now is when it touches the ground it kind of bounces forward too much. But this is a great starting point, thanks alot

[mellow folio]

so basically when things are moving, particularly either very fast, or when framerates are low (therefore causing each frame to push the object very far, which is a type of "speed') -->

What happens is, an object can pass all the way through the thing it was supposed to hit from frame A to frame B, meaning that the 2 things never actually overlap

[urban haven]

Apperently not, I think you have to attach each BP to the variant that is being called...

[mellow folio]

Consider that landscapes have essentially 0 volume vertically, so a "bullet" shot at a landscape would frequently never "overlap" it

[trim matrix]

I see, I figured it might have something to do with the verticallity aspect. thanks for breaking that down for me, really appreciate it.

[mellow folio]

another solution would be to increase the size of the projectile

whatever the overlapping component is

by increasing its size, you could effectively ensure it doesn't move greater than its own radius in any given frame

but CCD should work too...

[thin panther]

You dont

If you do what i said

So get all of the bps and change the resukting vars

Hinestly this sounds like something you want an editor bp for

[hot lotus]

If you have a small projectile you could linetrace also, depending on the projectile count. If you linetrace previous frame position to current frame position. Something like melee linetrace

[trim matrix]

Hi everyone! do you know how to kill/delete staticMeshComponent (spawned in a BP) that are outside a specific geo?

trying

is it working with staticMeshComponent too?

[faint pasture]

There's a bulk edit thing

[hot lotus]

I think there is a component overlap function that takes two components, how is your geo defined?

[onyx token]

is it very expensive to make every function a component?
Like doing an action - component
moving - component
inventory - component
equipping stuff - component

Hey guys, I have a nooby question about arrays.

TLTR:
-Made an Array with 2 SM (short 100cm, Long 300cm)
-First and Last Mesh can be set by me
-Middle Mesh is Random (Array Item from Stream) Instance Mesh

How could I get the Mesh Item for each Loop and change the Y Location accordingly, to make it fit to the last random mesh?

[brave robin]

I'm still struggling with the "loop delay" problem
But when I put a breakpoint on the same delay, it just doesn't work.

[gentle urchin]

Loop delay?

You'd need a custom macro for that if you ain't got one yet

[brave robin]

I don't quite understand why I need to make a macro
Will this reduce the "noodles" of the nodes and make complaints about the node disappear?

[gentle urchin]

The default macro doesnt give you delay funcionality per array element

Assuming thats what you're after

[gentle urchin]

The branch here doesnt make any sense . Youd need to multiply the index by the distance the item should be displaced with , in the direction from Start to End

Id also suggest some rules to either fix diatances, or have some code to morph one of the pieces to fit a finer displacement

you can't. components work with actors, not other components

you can use a timeline a lerp between rotators for components

I mean im sure it will be fine without the delay

nope, spawning thousands of actors with forloop freezes the editor untill its done

Still not working

[little trench]

multiply forward vector value with a float (like 10000) and add to player controller location, becoz it needs to locations, forward vector is not a location it's just a vector, then set that to target

[leaden dock]

is there a bp node to do a modulo?

[native terrace]

i think you'll have to write small macro for modulo

[leaden dock]

is this actually modulo?

just wrongly named?

[little trench]

i think your particle effect has it's own local rotation, like 90 offset or something.

try change this value and find better rotation

[south pier]

Well sometimes it shoots to the left of the line trace and other times it shoots to the right of the line trace

[little trench]

you can use trace start location and end location to find look at rotation node as well, maybe it will give better result

[south pier]

Negatory

[analog hazel]

Hey guys Is there any other options for setting set control rotation with a different node other then the "set Control Rotation" node?

[grand valve]

For yaw, you use UseControllerRotationYaw, but pitch is more suitable for something like an aircraft where the pitch of the entire object actually does change. Instead of UseControllerRotationPitch, you should attach a camera to the Pawns head, and set "UseControlRotation".

You can set it to "ignore" collision on that type of object. If you need you can go to your project settings and create a custom tag for those items and then set them to ignore in your character

[steady night]

@red fossili change it to "no collison" at all but then the simulate physics dont work :/ ?

[red fossil]

No you don't want it to be set to no collision, make it "custom" collision mode in your character bp, then change your items to "ignore"

one sec

https://youtu.be/ohR5P_zzgtc?t=630

He shows how to do it here^

Ah it's called Object Channels

So make a new object channel, go to your item, set the object type to that new channel, then in your character collision, tell it to ignore that channel

Hi guys!

Is there anyone here with experience of working with world composition and how to handle loading screen from a main menu to the world? Currently it just looks really scuffed when loading in unfortunately, as you can see some of the world popping in when it's "finished" loading

[karmic shadow]

I have a huge amount of AIs covering the world but Only certain of them are move, While the rest detect the move they should move to but Don't move, Please help me

Simply start the timer if the timer is not already running, and the target is the same

Personally id have this logic in the enemy so it'd be easier to handle

Ans you can easily have different reactions on different enemies

I'm running a setText function on the Construct script of a widget (it's a button) - in the parent menu, these widgets are added as part of a loop - but what is confusing to me is, it's setting the text for the button as though I'm passing through an index but I'm not -

So it works, but it's not supposed to - for example, the 2nd item in that enum is Par Check - but when I create the widget, I never pass that info in, so it should read the very first item, which is Rescue in this case -

1st image is Construction Script of Widget
2nd is the Parent widget that loops through and creates that widget

Define 'certain points'

Perhaps an example

[ancient vine]

the white dots

[gentle urchin]

So spline Points?

[ancient vine]

yeah

[gentle urchin]

Usually you'd probably wanna go end to end

Otherwise you need extra config for the moving platforms

[ancient vine]

yeah but for what I want to do I need each platform to move to a point and then wait for the player to jump on it before moving to the next point

do you know how to do this?

[gentle urchin]

I can think of a few ways yes

A timeline is prob the quickest

Timeline lerp from spline point to spline point

On complete, update target point. If current point = last point, reverse

[ancient vine]

Thanks gonna try that now

[gentle urchin]

Keep track of the current point outside the timeline loop :)

[trim matrix]

Hey, so i tryed a different design now. And my game keeps crashing.

[odd ember]

makes sense, that looks like an infinite loop

[trim matrix]

ur right

[odd ember]

also that delay on tick does nothing for you

[trim matrix]

okay

[trim matrix]

do u know how i can list all the pawn names in a list? with like a list box?

[odd ember]

what are you trying to make?

[trim matrix]

like a list where all the names are listed

[odd ember]

well you can do what you're doing

but just cut the execution that goes back into it the loop

[trim matrix]

i optimized it a little bit

should i use a list view for this

[grave hearth]

Have I gone* blind, or is there no way to change Datatable row names anymore?

[trim matrix]

Hi everyone! i'm struggling on something.. i want to make the X position of an object to oscilate slowly between -10 to 10... but i can't find a way to control the speed of the oscilation.. how would you do oit?

[stray wren]

hi! so I made a laser for an enemy that does a sweeping type effect but I want to add some sort of damage or burn effect to the ground where it hits, how should I go about that?

https://blueprintue.com/blueprint/syu4af77/ heres the blueprint for the laser attack

[trim matrix]

Hey CE can you maybe accept my friend request?

[odd ember]

no thanks, I don't do that

[trim matrix]

hm okay

[gentle urchin]

Double click the row name?

[grave hearth]

Tried, but not working, right clicking doesn't work either

[frail meadow]

Am i the only person where the UI colors got reset when upgrading to UE5?

my entire UI used to be dark and now its white

[grave hearth]

Composite datatables seem like they work "normally" though

[gentle urchin]

You're in the wrong view are you not

[grave hearth]

OH

You're right

Didn't know there are different ones until now lol, thanks

[gentle urchin]

You never noticed two different panels? 😅

[grave hearth]

I didn't even know you could edit that panel view haha

[trim matrix]

How do i add a collision to my bp character AI

[grave hearth]

Mine's been dark throughout all versions of ue5 I've tried

[trim matrix]

Hey do u know how to list an array inside of an List Box?

[odd ember]

do like you did with the foreach loop

[frail meadow]

but i mean my widget BP's

[grave hearth]

Ah, my widgets are as before I cloned my (4.26) project

[trim matrix]

like this?

[odd ember]

I don't know why you keep adding the loop back yourself

it already loops inside the foreach

you don't need to loop it

[trim matrix]

okay i will remember that

so this will add all actors in a list

[odd ember]

take a look at some tutorials for list view

[trim matrix]

okay

[odd ember]

to see how it works

but other than that

the logic is correct

[trim matrix]

i looked at the documentary. The compiler says theres no Entry Widget Class Specified on this list.

[odd ember]

take a look at a youtube tutorial

I recommend MathewW's channel

[crisp badger]

Hey everyone, just joined because I'm having issues with referencing an actor in another scene. Basically, I have 2 scenes, an interior and exterior - when the character walks from outside to inside there isn't an issue as the spawn place for the character is at the door. But when I move from inside to outside the character spawn sin the default location where the game starts; but I need him to spawn by the door of the building he's just exited - I was thinking of just setting the characterActors location during the loadscreen but I can't figure out how to reference him - any ideas?

Here's a little example, so as you can see when the exterior scene starts he's in the center of the road which is fine. But when he exits the interior he is then also in the middle of the road

Is there any UE4 bug where a break on an event will not fire even though you are watching the event fire (and are making it fire)

shit

that break never fires

[toxic forge]

Hello, did they change how BP events work in UE5? when i for example want to create OnTakeAnyDamage it makes me bind it manually

[dawn gazelle]

The event is called "AnyDamage"

[open crypt]

Is there something special about widgets that makes them not have breaks fired?

[neat surge]

Hello, fellow devs, I am facing an issue. So I am trying to push the "Sphere Object" when it hits the "Linetrace" using the Timeline code below everything is working as intended when I have set the framerate to 1000 basically Uncapped.

Footage With 1000 FPS
https://streamable.com/mjexou

But everything breaks when i test the code with low FPS in this case 10 FPS

Footage With 10 FPS
https://streamable.com/o7i29h

How can I make sure that the results are the same for every machine no matter what the frame rate is code is below.

Event Tick Code
https://ibb.co/bJMp7xy

Timeline And Setting Velocity Code
https://ibb.co/YBdbH5f

[icy dragon]

Event Tick executes on every frame (at least by default)

[gentle urchin]

This seem like some very odd setup

Especially if tick is playing the timeline from start each tick

[white elbow]

I want to make my gun project a ring that indicates the weapon spread, how do I do that? I'm thinking about either some sort of decal or however those quirky modders make your flashlight a shrek face

Can you make a spotlight project a custom image, or it's something else entirely?

[gentle urchin]

I think you can apply a light function that defines how the light behaves

[open crypt]

This is why you want to not do event based actions on tick

[gentle urchin]

But for the spread of your gun a circle probably suffice?

[icy dragon]

Light functions.

Though nowadays we usually use IES profiles for flashlights, which admittedly not viable for Shrek

[white elbow]

why not?

is it something that doesn't support custom images?

[gentle urchin]

Just go for decal

[white elbow]

actually I guess I'd need something that acts like a projector rather than a flashlight

[gentle urchin]

Decal, there you go

[white elbow]

no idea how to use decals yet tbh, this is gonna be a fun night

[gentle urchin]

It may not even work right tbh

Its projected alright,

But "flat"-ly so

Perhaps some niagara emitter is better

[white elbow]

niagara?

[gentle urchin]

The 'new' particle effect system? Replacing cascade

[white elbow]

so it won't work on two separate surfaces, for example if you're lighting a corner?

[gentle urchin]

The size will be the same on two surfaces at different distances

Which means one of the surfaces will display the wrong spread

[mild jacinth]

hi does anyone know why input would get disabled when using 'set view target with blend'. imagine i have 1 bp actor(non-character, just BP Actor) and i enable input for it at beginplay. but when i use 'setviewtargetwithblend' then the input is not recognized anymore. why is that?

its probs something easy but im not thinking correctly

[lime fox]

hi anyone have an idea how to solve this? like how do i either stop the character from walking off the edge or make him fall if he does.

[mild pine]

So as a way to prevent the issues I've been having with huge framedrops when the player is restarted, I was thinking that instead of using RestartPlayer I could simply teleport the killed player to a spawning location and reset all his variables. Does that sound like a good workaround to you guys? In this case I guess I would be using the GameMode override to get a random PlayerStart location and use that to teleport the player?

[sweet birch]

had to go away for a bit sorry, what do you mean by 'car transform'?

[late agate]

Hi there
I'm pretty new to unreal and I was wondering when I copy blueprints from blueprintue.com, how can I get the variables and components?

[echo salmon]

Is it possible to add meshes icons on Menu widget ?

[tame pecan]

With components, you have to create them, but with variables you can just right click and press ”Promote to variable”

[late agate]

Okay
But in many cases I don't know exactly what component it is.
And is there a way to generate and connect all missing variables automatically?

[tame pecan]

Component is just a thing that lives under a actor. Could be a inventory or a static mesh or whatever

No there isn’t

[fallen abyss]

I am currently implementing a UI mockup I made but my viewport in ue5 is (obviously) not 1920x1080 (16:9). How can I make it that when I play the game it takes a set dimensions

[late agate]

As a simple example
The pasted blueprint had a CapsuleComponent. But it could be a capsule collider or just a static mesh called CapsuleComponent.
I'm a bit confused how to figure out which component was used in the original file

[neat surge]

@icy dragon @gentle urchin so i should try to take out as much code as i can out of event tick?? in this case the SphereTraceByChannel and as for the timeline it is inside the InputAxis Upon Button Press it gets executed

[sharp yew]

how can i make a physics object not interact with another specific object?

[frozen rivet]

how can I see in lyra project how they attaching the weapon to the hands?

[fallen glade]

how do you get the index of an ENUM?

[faint pasture]

It doesn't have an index but you can cast it to an int to get the int representing it. Why would you do that though?

[fallen glade]

Cool, thanks! Just to switch things around, I have a bunvh of stats like health etc that I find easier to keep in mind reading the enum

[obtuse dawn]

so im having a problem where I switch the player mesh from the original and it just goes through everything

heres what I mean

I have tried changing the collisions and it wont work

[fallen glade]

does it have a collision?

[obtuse dawn]

yes

[fallen glade]

is it set to block all?

[obtuse dawn]

yes

[fallen glade]

how do you move it?

[obtuse dawn]

WASD

its on the flying template

[fallen glade]

is it set to collision both

[obtuse dawn]

let me check

yes

[fallen glade]

mmm how do you actually move the ship? are all of these set to block? also, are those boxes set to block all to?

[obtuse dawn]

oh I got it working with a work around

thanks

[faint pasture]

What? That sounds..... really wrong. What are you trying to do?

[fallen glade]

Well it's working, can't be that bad 😛 (probably is) so I have a stat struct and a struct containing all the stats. I find it's easier to operate on them like this when tweening etc @faint pasture how bad is it ?

[open crypt]

sequences don't take delays into account correct?

[rain heath]

What's better, blueprints or c++ for a game kinda like Forza/GTA

[thin panther]

the answer is both

you want to use elements of both

complex systems and tick based systems benefit from c++

simple gameplay can benefit from bp

[dense furnace]

engine is designed for both to be used really

[open crypt]

You want to use blueprints when you have generalists or artist who don't program but can understand some basic logic, blueprint helps make your systems more modular so other people can work on them

[rain heath]

I understand c++ but I'm also making automatic functions that fire off at a certain time in real life.

[mellow folio]

Blueprints are faster to write, and therefore free up the programmer to spend more time building and potentially even profiling performance problems. C++ code just runs faster, and has some additional flexibility.

If you need to program very big systems that change frequently or in ways that require lots of computation, those systems will need to be written in C++. If you need big tools that the engine does not provide, like a large scale custom pathing solution, you'll need C++. Most everything else is more efficiently built in BP.

However, there is a huge difference in performance between bad BP and good BP, so either way you're going to have to git gud.

I personally recommend that general learners should master BP first, unless you want to get into C++ right away to reap its rewards.

[rotund marlin]

Question, If Clients fail to see where server playercontroller is aiming with linetrace, is it a replication issue in BP or is it configs somewhere?

[mellow folio]

If your game is going to be small, or programatically simple using existing tools, C++ will probably just slow you down.

[mellow folio]

Whose controller is it?

[rotund marlin]

Server/Client 0

[mellow folio]

Is it his own controller?

[rotund marlin]

server can see clients aim, Clients can see server shot

but client cant see server aim point

client just see straight shots.

[mellow folio]

Oh, well clients never have any copies of anybody elses player controller

that is never replicated

only the server has copies of everyone elses controllers

[rotund marlin]

Ment Camera line-trace

[mellow folio]

So that player controller doesn't even exist (on the client who is interested)

[thick palm]

Sorry to interrupt, completely different question.

Does anyone know how I can get gamepad input to manipulate a mouse cursor?

Essentially all I am trying to do is have a simple solution to navigate menus with a gamepad by building an artificial cursor sort of thing. Any insight is appreciated :)

[rotund marlin]

Well panther thing is, its The camera of a pawn, that is controlled by controller, Which fires direction of the line-trace that client fails to see

and its client > auth check > multi casted in start

So.. I have a custom camera I made that I can rotate/zoom/etc with my mouse. If I want 100 characters in my level and want to use that camera on a springarm for any of the characters do I have 100 characters with cameras and springarms? Or do I need to look at dynamically attaching them when the user switches characters? I'm new to UE.

[rotund marlin]

im guessing i can't use Camera as the aim for multiplayer linetracing just

[icy dragon]

Depends on how you setup the camera, really. Spring arm + camera on all of them would barely take a toll on perf, as they're not really doing anything until you possess them.

[flint wharf]

@icy dragon Thanks good to know there isn't a big performance cost I guess that was my main concern. That and I don't know the 'best practices' for anything yet. Not a lot of tutorials talk about big picture stuff.

Does anyone know why my AI is always stuck at the corners of the nav mesh

You will need a lot of good c++ code to pull off a Forza/GTA clone no matter how small in scope

Singleplayer you could maybe make a prototype with walking dude and getting in a car and driving but nothing as complex as those

[thin panther]

thats a fair point

even though there is a way to go about it, that project will be dead before it starts

and definitely not hosting it on your own server's or someone else's

Guys how to refer a blueprint class in c++

[faint pasture]

Not 100% sure but pretty sure you just don't

not as the BP class anyway

[trim matrix]

Got it.Can you plz answer my question in multiplayer section as well

[undone surge]

which character is this a ref to in the new ue5 anim bp eventgraph?

[maiden wadi]

Most likely the one who has the skeletal mesh that is running the anim instance.

[undone surge]

BP_ThirdPersonCharacter or it changes based on the current mesh

[maiden wadi]

You're mixing instances with classes.

[undone surge]

oh

[maiden wadi]

Any Actor, be it an Actor base, Pawn, Character, etc can all have SkeletalMeshComponents. A SkeletalMeshComponent houses the AnimBP. This also means you can have multiple AnimBPs per actor, one per skeletal mesh. This node just gets you a reference to the actor that owns the skeletal mesh that is running the instance. If you're running the instance on BP_ThirdPersonCharacter, you can cast that OwningActor to that and it should succeed.

[undone surge]

i see

thank you

[icy dragon]

You can't.
BP is on top of C++.

Hiya. I would like to have my character enter a puzzle, such as a door combination.

How would I handle this transition? Would I just move the player controller? Possess something different?

[gray lantern]

How do I get the on clicked function from my widget into my blueprint? im doing this atm but it's so dirty

[mellow folio]

Make an event dispatch on the widget

[gray lantern]

so like when my onclicked happens in the widget it fires in here

[mellow folio]

When the widget is clicked, have it call its own ClickDispatch event

When the widget is created, have the BP creating it BINDEVENT to ClickDispatch

[gray lantern]

sorry very newbie programmer

[mellow folio]

that is a BINDEVENT node

you want to CALL the dispatch

[open latch]

How would you go around creating a roar ability

what it should do is let out a "yell" and it should destroy meshes infront of the character ( specific range)

[gray lantern]

Sorry then how do I get this into the BP

[mellow folio]

yeah that's right

now when the Widget is created, BINDEVENT to WidgetClicked

drag off of this

[gray lantern]

yup

[mellow folio]

now drag off that little red pin

and create the event you want to fire

the dispatch should not exist on your BP....

[gray lantern]

This works

thanks so much

just creating a little controller for my Niagara system

[undone surge]

guys one of my animations is moving my character. how do i get character to stay in that location after animation is over? what would i use to set the location to the current location of the mesh

[summer schooner]

@open latch I'd recommend a Multi sphere trace set to the width you want the shout to affect, starting at the source of the shout and then doing the check for X units.
Or if you want to have it move over time(wave like): Multiple sphere traces that grow in radius. Like: Multi sphere trace at location X,y,z with a radius of 10 -> delay 0.5 sec -> multi sphere trace at x+1,y,z+1 with a radius of 20..... for example.

But there's probably a better way 😄

Is there a built-in or preferred way to use config variables such as player-set control mappings, render options, etc?

[red fossil]

I've been trying to straight up add character velocity using my right vector, but it hasn't really worked the way I intended

[open latch]

Where is chaoseditor in 4.27 ?

[red fossil]

Well it did work, but it pushed my character left and right instead of rolling it

[scenic magnet]

I'm sure I could figure out how to manually code what's needed to read/write from disk and populate global vars, but I'm guessing there's already something that does it. Anyone?

[white elbow]

there's AddWorldRotation if that's what you need

how to achieve this option left right?

is this combo box

i mean that medium slider left and right

if left is click turn into easy

if right is click turn into hard

how to set that

Hiya. I would like to have my character enter a puzzle, such as a door combination.

How would I handle this transition? Would I just move the player controller? Possess something different?

[odd ember]

you'll have to be specific

[fleet cedar]

I have a third person character, I want to have him do a puzzle, like jigsaw for example

I've created the interaction events for it, but I just am not sure how to go between him and the puzzle mode

[odd ember]

right but what do you mean by that?

well what is "puzzle mode"?

[fleet cedar]

So the camera would go into First Person, He would hide, but what am I controlling? Do I possess the puzzle? Do I just hide him?

The controller input would change, he no longer walks, just moves a '2d' cursor

[odd ember]

probably a separate puzzle actor pawn

that you can then defer input to

[fleet cedar]

Okay, that makes sense

[odd ember]

you could have it own the puzzle pieces as well

so all the inputs are in the pawn even when you move the pieces around

and you could enable specific inputs only for the puzzle mode

[fleet cedar]

I essentially want to swap into this from third person char

[odd ember]

right so does the above approach not work?

[fleet cedar]

I will try! Thanks

I didn't know whether to put it in a pawn or what... It makes sense to me to move the functionality out of the main character BP since it's going to just get confusing if it's all in one

And I'd have to disable so much of it while in that mode

[odd ember]

yeah if it's truly a "mode" it's always easier to have it separate

[fiery glen]

think of the pawn as what you currently CAN do and the controller as what you want to do

So

Hmmmm

I'm trying to make a custom gravity simulation for my game, issue is that the simulation cannot handle more than abt 50 or so objects (getting slower and slower the more they are added). I'm fairly certain its because the process is not optimised at all, so I would like to try out two body gravity simulation which is that all objects only interact with the gravity of whatever dominant gravitational influence they are in.

IE. Planets would only interact with the gravity of the sun, and moons with their parent planets. Edge-cases are allowed however, like when two planets get close enough for their SOI (Sphere of Infleunce) to overlap and therefore shift the gravitational infleunce from the sun, towards the planets.

Albiet, probably make it so everything still interacts with the Sun's gravity

So erm, anyone willing to help me out with this?

I will admit, I think I gave myself a super difficult task for this lmao

[odd ember]
