blueprint

[novel ice]

Oh

Thanks

[fiery swallow]

Do you know what I mean by that?

In your situation it doesn't look like a montage is necessary, a simple play animation should be fine

Destroying an actor in the middle of a line executes everything else immediately. Maybe moving it to the end will fix your problem

[pale orbit]

does anyone have any idea why is my movement like that when theres a camera on the actor?

in the second part i take the camera off

and its smooth

[proud sable]

I'm very new to UE and trying to set up a HUD switching system. The game has 3 characters, with eight total abilities each. The player can switch between them and hold shift to access the other four "secondary" abilities.

Right now I have 6 different HUDs that I swap between when a different character is possessed and when the shift key is held. I know this is probably super incorrect but I haven't been able to find anything digestible for a beginner online to help with this.

How do I improve this system and hopefully get it to work with only one HUD blueprint? At the minute the main hurdle is figuring out how to swap out the icons and portraits for the appropriate player character, and bind the AI health/ability cooldowns to their widgets.

Is there somewhere I can read up on this to get up to speed and do this right?

[shut hinge]

having a problem with a state machine in the commander pawn. Doesn't appear to be working. I think hes using third person character's inherited state machine because when I plug in the state machine in the commander, hes not responding to it.

Anim instance is listed as his parent class for his state machine.

[proud sable]

Thank you! I don't fully understand but knowing it's possible and the terminology to use when I google it helps. Before I look into it more I'm guessing this button is how I reference a variable for the image?

Oh sorry I didn't see the bind button above the image selection, thanks 😅. I'll watch some more tutorials, the course I was following only covered the attribute bars and cooldowns for the main player character

[unkempt musk]

Anyone have an idea as to why my camera wiggles to the side for .5 seconds when I change directions?

[odd nova]

hi. im trying to implement easy balistics, but the bullet dont go to the center of the screen (TPS). any ideas where to look? cant find any option for that

[shell ember]

if you want the bullet to go to the center of the screen then you should use camera for aiming not the player

[odd nova]

ok thx

[faint pasture]

@odd nova first or third person?

[fluid rose]

What's this node?

[faint pasture]

If it's third, welcome to hell. Getting the design tight will be a bit of work but it's doable. You need to think about how to determine the depth of the intended hit.

[faint pasture]

Vector x Float

[odd nova]

@faint pasture, TPS. i have a working solution, but i wanted to use easy balistics, but, no, going back to my working solution lol

[fluid rose]

I can only do Vector x Vector

[faint pasture]

@odd nova the ballistics don't matter. Presumably you just feed it a start point and direction for the shot. Calculating those is what you have to worry about.

[fluid rose]

Found it, thank you

[faint pasture]

Is that ue5?

[sand shore]

the best way to do TPS OTS aiming with the projectile leaving the gun is

1. Run a sim from the gun itself
2. Run a sim from the camera
3. Do some kinda lerp between the two and have the visual element follow that

And you can do some magic to get a better aim point for the gun

[smoky elm]

Does anyone know how to use the AI MoveTo function on a model which doesn't have animations?

[faint pasture]

Animation shouldn't matter but.i think that node only works on Character

Don't quote me on that but I think it uses the CMC

[sand shore]

AI Move To should be using pawn interface (eg, SetMovementInputVector or w/e)

[smoky elm]

Any way to do something similar not on a character?

[sand shore]

Ought to be able to consume that input vector and drive locomotion that way

[delicate folio]

hi just a question that i was wondering - is it possible to involve the landscape design into the blueprint for example if you have a forest landscape can you make it so when the player character goes into the forest their movement is slowed due to the landscape they have entered?

[sand shore]

But you have to play nice with the navigation mesh too - so no flying stuff

[sand shore]

easily a dozen ways to do this

probably no single best way to do it, try out your first idea for how to do it

[delicate folio]

i havent really got an idea of how to do it in the blueprints i just thought of it being possible right now tbh but i shall try if anyone does know of a way or has any tips then much appreciated and thank you

[sand shore]

I could give you a solution, but I prefer to nudge others along the path instead of just teleporting them

Also my solution is going to be harder for you to understand/implement

[zealous cave]

Good morning everyone, I'm not understanding how to reference actors. I've reviewed, https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/ProgrammingWithCPP/ReferenceAssets/ , but this hasn't been very helpful.

The level I'm working on is a basic ThirdPersonExample. I have a character starting on a small platform above the floor ready to drop, and a cube floating next to him with physics enabled so it'll fall at start.

The idea is when the cube touches the floor it disappears, but when the player touches the floor it gets teleported to the start platform.

I'm hesitant to create all of these conditions at the Level Blueprint level, thinking its best to create these actions per object in either the class or the object. Since they are class specific. This would also be helpful if I have multiple players or objects that should respond in different ways to colliding with the floor.

[sand shore]

Start here https://www.youtube.com/watch?v=EM_HYqQdToE - don't use C++ stuff if you're doing it all in BP

You want to take advantage of "natural" ways to gather/store references to objects.

Eg. Begin Play -> GetGameState -> GameState->RegisterTrackable(this)

Eg. SpawnTrackable -> SpawnActorOfClass -> RegisterTrackable(SpawnedActor)

All that is reliant on Game Framework knowledge

You can also GetAllActorsOfClass but it is the laziest way to do things

(other than GetPlayerCharacter(0) which is great until you do multiplayer)

[zealous cave]

Thanks @sand shore I'll check this out.

[zealous cave]

the tooltip says its slow, so I'm opting to stay away

[slate apex]

Does stuff like this take too many resources?

i'm making a 2.5d Game

so nothing really takes alot of muscle to run

but then i have event tick like this

yes even italians are mad i murdered spaghetti like this

but uh

yeah.

[maiden wadi]

Realistically, you should avoid using any GetAllOfSomething calls. Create the widget once, place it in a pointer. On overlap check if that's valid, if so if it's on screen, do nothing. If not on screen add to screen. Then on end, check if it's valid and if yes, remove from parent.

Even better. Put this functionality somewhere common like the HUD or Controller. Then you can reuse it multiple times for multiple interaction things instead of putting it in every interactable.

[last abyss]

well its not a loop, you only disable the outline on the last stored target

you could use an array, store the enemies in it when they are hit by the multisphere trace then when you disable it use the array with a for each loop

and ofcourse clear the array when the loop is completed

nope. So you check if you hit an actor with the branch (hit actor == none). Off of the true you can do the for each loop the same way you're doing it right now.

[trim matrix]

Hello

Can I change the postprocess setting using a blueprint?

[olive sedge]

Guys I've been at this forever now, I'm not getting a reading on my spline rolls. I have made a minimal example here: https://blueprintue.com/blueprint/e975kcyq/
I would expect a reading of anywhere close to .17 but I'm getting 0.0

[last abyss]

yeah, that's what that would do. is that not what you were trying to achieve?

And how are you calling the 'set target enemy' function? on a timer, tick (i guess tick is a timer xd) or on click?

[frozen needle]

Need a quick help. What am I missing? This worked fine before, but now it gives me an error on end overlap

[sand shore]

When you cross wires between the major paths, you are using the other reference

[frozen needle]

Should I set a reference to the character after cast then?

[sand shore]

So, say you have many things overlapping your actor after you start overlapping the right thing.

That cast node failed on anything that isn't a BH_Milo_BP - when you use the reference on End Overlap (when Moving In is true, notice the top node references the cast which is from Begin Overlap) you get nothing

Or vice versa

[frozen needle]

should I use get all actors of class instead?

[sand shore]

Oh actually you're always using the other reference

[sand shore]

No

[frozen needle]

What is the solution then? If I have multiple casts going on

[sand shore]

I'm getting to that

[frozen needle]

Oh ok

[sand shore]

I've split this into two sections, 1 and 2.

The sections are roughly defined by the output of the nodes (Say the result of the Casts) and whether they originally run from Begin or end

Orange here represents a typical End Overlap path

See how the node you hit at the end of 2 references data from the start of 1 - all the time?

The solution is to only reference things from a like path - either 1 references 1 or 2 references 2

That means you can't do this thing where you cross execution wires over this line

[frozen needle]

Oooooh

[sand shore]

do this

[frozen needle]

I see what you mean

Yeah just done that

Thank you

[sand shore]

and don't do these (at least like this)

If you need to do a return, you need to find a way to not cross data

[frozen needle]

I just want a way to prevent my camera from snapping if player goes out and back into the trigger box quickly

[sand shore]

I see

Hrm,

[sand shore]

Maybe just doing the data wire fix here will be enough.

Try keeping your call to Return

(but, the reason why that might work is because the values of the move are stored when you start it... maybe)

(Not real familiar with that node)

(in general, what I've said is true - you don't ever want to call a regular node with crossed data wires -- async nodes are a little special)

async nodes always have this icon (so you can tell the difference)

[frozen needle]

The thing with bools don't work 100% cause it still doesn't help from rapid spamming, but hopefully in normal ADHD-free conditions it will do the job

Why is it bad anyway?

[sand shore]

Crossing wires?

[frozen needle]

Yeah

[sand shore]

You can easily get the error you just got lol

[frozen needle]

ah

[sand shore]

But also you can easily get bad data (that is either stale or has not been initialized yet)

If you want to cross data wires over execution lines - store them as variables

[olive sedge]

Can someone confirm for me that this is broken?
https://blueprintue.com/blueprint/e975kcyq/

or tell me what I'm doing wrong

[sand shore]

you can click on these, btw

take you right to the node reporting an error

[frozen needle]

Yeah it didn't really show what exactly is wrong

[sand shore]

It does though, hah

[frozen needle]

I mean it didn't stop on the vector and rot variables which were the issue, just snapped to the "move to"

[sand shore]

you make a spline mesh that has no length (starting and stopping at point 0)
you make a second spline mesh that covers the entire spline length (but uses local space coordinates)

If the issue is that you don't see any spline mesh at all - you either forgot to specify a mesh (click on the Add Spline Mesh Component node, see if you configured the template properly), or you should be working in world space coordinates (check right next to world origin - if you see the spline there, that's why)

[olive sedge]

@sand shore oh, you're right. what should be the end position of the second (last) spline then?

[sand shore]

play with it?

Change the coordinate spaces?

Get the final point along the spline?

[olive sedge]

I did all that

[sand shore]

¯_(ツ)_/¯

I'm not an expert in the spline API

[olive sedge]

the issue is just that I get 0 readings on the roll

but yes.. I probably need 3 spline components anyway

I'm gonna update and report back

[sand shore]

I've heard roll is hard with splines

like some kinda bug with that

[lament night]

Good people I need help.
Seems simple maybe but I run out of hair to pull.
I have set BP for RTS camera to switch to 3rd person character.When I'm in RTS mode everything is fine(camera movement,edge screen movement and rotation).But when I posses 3rd person character my Mouse X and Mouse Y do nothing.
As you can see in image ,event are called and values are set 1 in binds,but there is not rotation.
When I change binds to random keys, rotation works fine.So rotation logic seems Ok.
If it's needed I can upload image of Possesion BP.

[zealous cave]

This was super helpful! Casting was a massive help. I'm only 30min in, and I've already solved both original questions.

This might be a n00b questions, but why is the ball sinking into the floor? I should clarify that it fell from above and thats where it stopped after bouncing a couple of times.

[olive sedge]

@sand shore I updated the post

https://blueprintue.com/blueprint/e975kcyq/

the generation is sound now but the reading is still 0

to everyone.. I can't get a reading from the GetRollAtDistanceAlongSpline and it seems to me like this is a bug. Can anyone confirm this?

[sand shore]

The channel pins have some useful things

[dawn gazelle]

It maybe has something to do with this setting - it would be on your spring arm or on your camera.

[lament night]

It's on,
Thing is,when I set for example Q key for x rotation it works fine.Only when I set Mouse x for rotation it doesn't work.But Mouse X works for camera when I'm in RTS mode.
I'm guessing when I posses new character player controller still hold mouse x for RTS camera interaction,but can't find issue.

here is my Bp for character possesion

[narrow kelp]

@lament night If you're possessing a new pawn, then any input code will need to be on the new pawn too

or on the controller instead

maybe thats whats going on?

[lament night]

I'm possesing default third person character(which has movement component) and rotaion BP is there, and Possesion BP is on controller

[narrow kelp]

Could be a couple things, might not be possessing it correctly, might not have your inputs set up right, or it could be a problem with your camera setup

those would be the first things I'd check

[lament night]

is one character automatically unpossessed when another is possessed?

[sand shore]

yup should be

[eager agate]

hello! is there a way to check the collision of a specific component in a blueprint?

i am trying to cast to a character, but i dont know how to check the certain component that needs to be passing

[dawn gazelle]

You mean at runtime?

The "Other Comp" would tell you what component it was that caused the overlap/endoverlap.

[unkempt fjord]

Dumb question here! I’m using completerpg as a game template. I’m duplicating the main character blueprint renaming it and plugging in my mesh and anim bp. BUT some functionality is broken. In general should I avoid ctrl c ctrl v of complex integrated blueprints and as a general rule create a child instead?

Or at least use the original blueprint but overwrite the skeletal mesh and animbp?

[dawn gazelle]

Probably best to make a child if you're not entirely sure what you may mess up. You can always override functionality if it's not behaving how you want it to.

[loud cipher]

Hey guys what is the blueprint to set an anim class?

I want to set an anim class on begin play

[loud cipher]

Thankk youu

[eager agate]

would you mind sending an example? im trying to check if a specific component is overlapping but i cant get it right

[dawn gazelle]

This would be how you could check for a specific component on a specific character.

[desert juniper]

Don't know if you've solved this or not, but check the level or game mode BP

[eager agate]

tysm

[desert juniper]

Sometimes they have an event for the input action of that key and it doesn't allow the input action event to propagate correctly

[lament night]

@desert juniperHave no BPs there yet.All clear.

[desert juniper]

If you're able to change the binding to other keys, then likely something is hijacking the keypress event, and not allowing the event action to be called

also, though you may not have written any code, the BPs have to exist

[lament night]

it looks like it's being called

and since other actor is unpossessed,the rotation for it shouldn't interfere with this

[frozen needle]

@sand shore So what about crossing stuff if it's something like this?

should I still make a copy and do it all separately or these variables are fine?

[dawn gazelle]

Generally pure nodes (like the GetPlayerController and the Self reference) are fine to span across like that. For cleanliness in your BP, especially if other people are going to be working on it, it's nice to keep whatever variables are required on your execution path to that execution path, and in some cases, it's required as you may be trying to call a reference to something that doesn't exist on your execution path which may cause errors to pop up that will be harder to track down.

As it is, there is nothing specifically wrong with what you have right now in that image - it will work 100% of the time, so long of course as your casts succeed 🙂

[sand shore]

yup

pure nodes can't even cross like I was saying

[frozen needle]

I see. Thanks!

[sand shore]

@trim matrix

because the pure node isn't triggered from an exec line

due to the nature of how they work

I'm explaining it terribly

but it's the thing

ykno.

THAT behavior

Anyone who needs a better explanation of the thing... I did a video that actually explains the mechanics

[dawn gazelle]

There was this audio software I used to play around with some time ago...

[sand shore]

in the pins

[trim matrix]

I used level streaming for foliages so instances would be handled seperately

anyways I set it up looks okay in editor when I play none of the levels get loaded

couldn`t find any thing online about it ugh

and its not even client side yet

it does this on offline as well

[sand shore]

sounds like you need to load your levels (because they aren't always loaded)

there's a node to do it

[trim matrix]

yeah i kind of found something about initally loading but that option no longer exists

I thought world composition handled this automatically tho

[sand shore]

oh I have no clue on WC

[tall jacinth]

Anyone know where I can find some good tutorials on Blueprints/Visual scripting with Unreal 4?

@dawn gazelle thank you

[loud cipher]

Hey all

I have setup a system where my game displays the coins gained from picking up a coin

I have created a text binding that gets a reference of the coin

then gets the integer of the coin amount added

and then its plugged into the text bind output node

However i was wondering

it just displays the full integer value

how can i have it display a +

along with the integer

[desert juniper]

append the text

have the display text bound to a text variable instead of an integer variable

and use an Append String node to append "+" to the coin count ref

[loud cipher]

Tysm

Yeah

It worked

[desert juniper]

np 🙂

ah the variable was already a text variable. great cuts out an extra step

[daring cradle]

So...the event Blueprint Initialize Animation in my AnimBP has just stopped working

Cant seem to figure out why 🤔 wondering if this is a shared issue?

[dry pewter]

Maybe sharing a screen of the node setup might help to picture the situation? or telling wym by "stopped working"

[trim matrix]

Is there any way to split foliage instances.

I have too many and removing / transforming one of them gives massive drop to FPS

[daring cradle]

This event just stopped firing. And this AnimBP is used on a spawned character...so you'd think it would initialize 🤔
Stopped firing as in previously it would function as a "beginplay" type event. Now it doesn't fire, even put a breakpoint on it

[trim matrix]

I tried level streaming with foliages split into different levels but that didn`t work as it still dropped even with 1 instance on one level

[daring cradle]

Hm...nevermind it does fire! But...well there's some other issue now lol i'll figure it out

[dry pewter]

I think you don't want to use the "get pawn owner" node but the "get player pawn" node, pretty sure!

Isn't that a question for #cpp ?

[smoky wasp]

Q: Hey guys, im trying to create a 'repeating conveyor belt' of cubes but when i 'teleport' object at end of line to the start, theres a lag in the timing. I uploaded a youtube vid that makes it easier to understand than any description i can come up with. Even if delta speed is constant there will be gaps in between cubes:

@dry pewter wasnt sure - I can move the question there.

Maybe someone there can help you 🙂

[ripe rose]

i have a thing in a bp that i'm trying to rotate to face each player looking at it. meaning, on your screen, you see it facing you. on someone else's screen they see it facing them.

how do i get the actor or controller owned by the local client? i need to get that so i can get the owned player's camera location so i can rotate the object to face them.

or maybe there's a different way to do this that i'm not realizing

edit: solved. seems to be "get player controller(0)" -> get controlled pawn, to do what i want

[opal ivy]

If I've got a Static Mesh component in my Actor, how do I make it so that the component's variables show up in the editor?

Specifically the mesh and material(s)

[thorny relic]

You mean when you have an instance of the actor selected in the world?

You can select the component from the tree on the right, above properties

[opal ivy]

yeah

https://i.imgur.com/Y5XSpX1.png

[thorny relic]

Or are you asking how to make them appear on the properties of the actor itself, without selecting the sub-component? Because I wish I knew that myself

[opal ivy]

I want to be able to click on the instance of the actor in world and edit the mesh inside a static mesh component

[thorny relic]

Click on the mesh component in the list to view/edit the properties of that component, instead of the actor

[opal ivy]

Right, I want it to be doable on a per-actor basis.

I don't want to inherit an actor just to change a mesh

[thorny relic]

This is on a per-actor basis

You select the actor in the world, and change its instance of the sub-component in the world

[opal ivy]

OH

Oh, I'm dumb.

[dawn gazelle]

Your player controller can do "Get controlled pawn" to get reference to the actor they are controlling, this will work on both server and client.

On server, you can do "Get controller" on your pawn. You can't necessarily do this on clients as they don't have access to all controllers, so in the case if you're doing get controller on a pawn, and it's controlled by another player, you'd get a null pointer reference.

If you're dealing with UI, you can use Get Owning Player which would return the player controller.

[opal ivy]

That does lots of weirdness with my construction script.

[ripe rose]

yeah those are all in reference to the pawn of the bp you're looking at though, not the pawn owned by the client

whereas what i was doing was getting the controller of the client from within a bp not owned by the client

[opal ivy]

How about this then... Is there a way to create an HISM that takes all the properties from a static mesh?

[prisma stag]

Hello, I have a 3rd person game and am currently setting up a placement system with it. As of right now you can make a selection, the menu disappears and you can click somewhere to make you placement. However, when the cursor is enabled for this, it moves the camera as well which Im okay with, but if you right click, it stops the mouse from affecting the camera and in order to make a selection you have to double click.

[opal ivy]

https://i.imgur.com/1Keufyw.png okay, but if Generate Collisions is true, why no collide-y?

[dry pewter]

Sounds like you want to set up your actor controller rotation

[prisma stag]

Its not the rotations thats bad, its the fact that when I right click I have to double click the viewport to make the selection.

[dry pewter]

Are you playing on the unreal engine viewport or standalone game? when playing on the viewport you gotta make some extra clicks

[prisma stag]

Oh I didnt know that. Let me test real quick.

[prisma stag]

The issue still persists.

[dry pewter]

Maybe the cursor is getting caught in some transition between affecting the menu or the placement system, is your "set input mode UI/GAME" correct?

[main halo]

Guys, please. I am on a frustrating problem here. I am for the first time doing melee combat and I have set a collision preset to Enemy, Player, Weapon.
I want to the weapon hit the enemy. Simple and generate a hit event to simply print on my screen (HIT)
I have create a blueprint to my weapon and when the game starts that blueprints is spawned in the world and attached to my player hand. That is working fine.
My Enemy is on my front and when I walk on my enemy I cant generate the hit event. I havent even filtered to only show me the hit when hit the enemy by casting.

Both the enemy mesh+Capsule component are with hit event and with type Enemy. Collision enabled (Query and physics) and hit result + overlap events true.

My weapon is with a skeletal mesh. Why it dont work? I know I can use a box collision but I prefer to not.

[dry pewter]

Yo i think i can help, wanna pm me?

[main halo]

Sure

[prisma stag]

Ok. So I kind of fixed the problem, but it brings 2 new ones, one I think I should be able to find online, the other is one I need help with.

I have it set up so that when tab is pressed, the input mode is changed to ui so that I can make a selection, then when it is released it goes back to game. Now for some reason it is still toggle, but that's what I will fix later.

The problem is, if I set the released to change inputmode to game & ui the placement works, but it doesn't make sense as when you make your selection for some reason the ui and cursor automatically disappear, and then when you place your selection it seems to be set back to game mode on its own.

[dry pewter]

Remember to follow the "set input mode" node with a "show mouse cursor" node

[prisma stag]

Yea, Im looking at my code and following the steps to see what is happening. Might have found it.

[near flint]

Hey guys, Is there a way to launch a character to a specific location? I want to make my dash action more accurate - and set the lunch by distance and not by force

[dry pewter]

Maybe "move to location"?

But that moves the actor in a straight line, so maybe setting various move to location to get the effect you want, there might be a better solution tho

[narrow kelp]

@near flint You could use some kind of interpolation. Theres lots of ways to move a character, it really depends on what exactly you need it to do.

[dry pewter]

I've got a question guys, so i have my Widget created and added to viewport, now can i "spawn" a text block on that widget?

[spark steppe]

yes but no

you would have to make your own custom widget which has an textblock in it

as you can only create userwidgets on runtime

[dry pewter]

kk, will try

[frozen needle]

the gate doesn't close on end overlap, which results in me being able to use interact outside of the trigger box. What is the issue?

[spark steppe]

did you debug if the event doesn't fire or if something before stops it from running through to the gate closing?

e.g.: if you change your mission bool in the area, your branch wouldn't go to false

[frozen needle]

it dies after this

that's weird

ah

yeah I just need to remove the bottom bool

[trim matrix]

I have a question I already know how to make a basic fighting combo system but I want to make it so that if I press the attack button and im in the middle of the first one then I hit the attack button again whilst in the middle of the first anim itll play out the last 2 no matter what.

[narrow kelp]

@trim matrix make a queue

[rough wing]

When I change the relative rotation of PerkScene, FloatingPerkSphere doesn't rotate relative to PerkScene but rotate as if it was a seperate object.

Doesn't make sense at all. When I rotate PerkScene in the blueprint, it works as it should (FloatingPerkSphere revolves around the center), but in-game it acts as if it isn't relative to PerkScene

[sonic pine]

Hiho I have a problem about Add to viewport on servers. I have already been told that widgets do not work on the server, but the UE forum tells me something else, but it says you just have to set the widget correctly. Unfortunately I can't find anything specific about it and I would have liked to have fixed it, I've been annoyed with that for long enough ...

1. Why do I get the Add to Viewport error before logging on to the server ???

2. What EXACTLY do I have to change so that add to viewport works (Healthbar, Minimap, Inventory, Character stats and so on)?

Oh yes, please talk about widgets if you mean widgets and HUD if you mean HUD and not widgets ^^

[dawn gazelle]

If you're doing dedicated servers, widgets don't exist on them, so you can't create them and add them to the viewport. They should only be created and added on clients.

Example: Begin Play -> Has Authority (remote) -> Create Widget -> Add to Viewport

[sonic pine]

in the third person character, so it should be on the client, i think ^^

[dawn gazelle]

Nope

Your third person character exists not only on your client, it also exists on the server, and any other clients.

So each of them would fire begin play when that actor begins play.

[sonic pine]

ok...

but the thrid person character is the point who should be able to see the widgets

[trim matrix]

thank you and uh Can you elaborate on that

[narrow kelp]

Sure, you could for example make an array of inputs that you add to while the action is going on, and when the action is finished you look at the first input and do what it says

[dawn gazelle]

Eg. I join a dedicated server. I'm the only player online. The server spawns a Third Person Character for me to posses- this Third Person Character is replicated to me. The "Begin Play" fires on both the server copy and the player copy.

You join the same server, now we're both online. The server spawns a Third Person Character for you to possess. The server replicates your Third Person Character to me, and mine to you. The "Begin Play" fires on the server for your copy, on my copy, and the begin play fires for my character on your copy.

[narrow kelp]

Then remove that input. You can add timestamps or limit to the last input depending on what you want

[dawn gazelle]

So it gets even more complicated when you're using Characters to create UI.... Because MY character will create a UI for me. Then when your character joins, it's going to create ANOTHER copy of the UI for me...

[sonic pine]

ok should i use something like a "widget_Component" to include to the ThirdPersonChar?

[white crypt]

if you want to add widget to the owner then make a custom event, set owning client

and add widget on that event

or you can also use is locally controlled and a branch

or

[sonic pine]

ah ok

[white crypt]

https://cedric-neukirchen.net/Downloads/Compendium/UE4_Network_Compendium_by_Cedric_eXi_Neukirchen.pdf

and read this

it's a must

@sonic pine pinky promise me that you will read it

and do your widget stuff inside player controller not your character

for second example to work you would need this, but better if you stick with the first example

[dawn gazelle]

I had to reference this diagram so much while I was learning... Now it's second nature XD

[white crypt]

i've learned it's much easier to work with dedicated servers

don't have to deal with the client/host being on the same machine

and you can use get pc/character

[jaunty orbit]

anyone know why this doesn't work

[white crypt]

did you include that montage slot to your animbp?

[jaunty orbit]

No how do I go about doing that?

[white crypt]

probably you just have the default one

so make sure it looks like in my example

[jaunty orbit]

so like this right? But it wont let me add the montage to it

[white crypt]

yup like so

now go back to your character bp

drag from mesh and type - get anim instance

then drag from anim instance and type play montage

and use that montage node, then it will work

[jaunty orbit]

still nothing :/

[white crypt]

show what you have

it was montage play, not play montage

[white crypt]

add a print string at the end

and see if it prints when you try to attack

[jaunty orbit]

it prints

[white crypt]

does your montage works when you open it?

[jaunty orbit]

i did retarget the animation from a paragon character by following a video

[white crypt]

because my last guess would be that you are using montage on the wrong skeleton

[jaunty orbit]

and yes it works

[restive dagger]

When I rotate the spring arm the camera does not rotate
any reason for that?
even the spring arm does not rotate

[white crypt]

@jaunty orbit does this slot inside your montage

is the same as in your animbp?

defaultslot

[jaunty orbit]

no in the montage it says upperbody and not defaultslot

[white crypt]

so inside animbp

change it to upper as well

and you should be good

[jaunty orbit]

thank you so much!

It's working

awesome, np

Hello.
How i add random float in material?
Pls, without using dynamics.

[white crypt]

that should probably go in #graphics , i could only give examples using scalar parameters

since i dont work with that stuff so no idea if there's another approach

[restive dagger]

Any way to get rid of the camera lag

stitching^

[dawn gazelle]

This generates a random float between 0 and 1 per instance of the material without creating dynamic material instances.

[white crypt]

you no longer need to create dynamic mats though

i know its irrelative, but learned this recently myself 😄

[restive dagger]

https://gyazo.com/eb1aa37ad7cdea44369aabf283342433

[icy dragon]

This channel is specifically for BP stuff.

[trim matrix]

okay

Im trying to create a Weapon swap system in my project much like how Enter The Gungeon works. it rolls through a list of weapons in order then once it gets to the last weapon it starts the list over again.

ill send pictures of what i have so far

one minute

Logic for checking Which weapon is Equipped

oh wait i think i just figured it out myself

Function for switching Weapons

Im not trying to save the Current ammo or mag size of the weapons at the moment. I would like it to just switch

Currently it switches from the Rifle to the Shotgun fine, but it wont switch from the shotgun to the Sniper

I think im missing information on how switches work, or im using enums improperly. but i cant find much on it.

[dawn gazelle]

Don't convert an enum to string. It's bad form and it won't work in a packaged game ._.

You may also want to use a select node rather than several branches.

As for what you have not currently working, your branching logic in the screenshot is broken.
You're checking if the current weapon is rifle, and if false, checking if the current weapon is again, rifle.

Last bit of advice is to not use tick at all for this. Wherever you're setting those booleans is where you should be calling a function to swap the weapons.

[trim matrix]

Thank you for pointing that out

Ok, I have it hooked up to a on key press, so instead of having the logic outside the function running on event tick, i should run the logic inside the function correct?

that makes sense when i type it out

Thank you again

[dawn gazelle]

Ooh and when doing the swap to the different class - that can be simplified too:

No need to use a switch statement if you are doing the same thing for all weapon types.

[shadow saddle]

i have no idea why launch chara only works well in Z direection

but never in x and y

in Z if i put 700 i can see i jump high

if i put 5000 on x or y it moves a tiny bit

[fiery swallow]

Wouldn't the simplest method be to use a multi gate and eat time it's called the weapon changes to the next one?

[shadow saddle]

if i put 50k to 100k it teleport to the desitnation

[trim matrix]

Oh what,

[fiery swallow]

Did you try overriding xy? @shadow saddle

[trim matrix]

sorry ill wait

[shadow saddle]

ye

[fiery swallow]

What are you trying to do? Launch character isn't really for XY only

It's kinda meant for launching which is Z

[shadow saddle]

ok so basically

im trying to add some force to my AI boss so when my chara is far away from boss, it perform an attack( animation) that launch himself to me

but the animation distance is short

im trying to push the chara in the animation

to make the AI travel further

https://www.youtube.com/watch?v=EJ0czOU1h5M&t=95s&ab_channel=RaymondN

@fiery swallow

check 0:20

[fiery swallow]

Launch Character is Additive. This is mind you'll move further XY depending on z

[shadow saddle]

which mean?

if im hanging mid air

i go further in xy ?

[fiery swallow]

depends on if you use override

[shadow saddle]

should i overide or not if i want to do whwat u said

[shadow saddle]

this

[fiery swallow]

If you are falling and then try to launch your character, without overriding, you'll likely just keep falling

https://gyazo.com/97103a299aea904e527a101bf9b62703

https://gyazo.com/3412df9997e18f854770d6c96aef9c16

One is with Z and one is Without Z, You can see the effect Z has on launch character

[fiery swallow]

If you're already on the floor, and not moving then you don't need to override. If you want the same launch results almost every time then yes you'll want to override

[shadow saddle]

ok tq

@fiery swallow

what is ur default global gravity z

[fiery swallow]

I don't know what you mean, All characters have a gravity scale and the default is 1.0

[shadow saddle]

nvm forget about it

i should try turn it off

[fiery swallow]

Yeah you should probably just keep things default unless there's a specific reason you need to override it in the world

[shadow saddle]

ah yes

now i know why things wouldnt work

i set gravity scale to 5000000

becuz last time jumping up took too long to drop to ground

thanks anyway

[elfin abyss]

Why does my cast to always fail?

[icy dragon]

This might help:
https://youtu.be/fVFo52cDKXY

[tidal marlin]

Thank you

[fiery swallow]

Because an actor is not a level. (Assuming that cast is a level due to it's name)

[elfin abyss]

They're both actors, i just named the other one ProcLevel cause i'm bad at naming

[fiery swallow]

is the actor overlapping that component either a parent or child of the actor you are casting to?

[elfin abyss]

No

[fiery swallow]

There's your problem my guy

[elfin abyss]

Oh

Fair point

[fiery swallow]

"other actor" grabs a reference to the actor that overlapped it

[elfin abyss]

I want my current blueprint to be a trigger collision box and once the third person character starts to overlap i want to call a function from BP_ProcLevel

[fiery swallow]

You'll need a different way to get a reference to the bp_proclevel actor in the world

[elfin abyss]

A variable like this?

[icy dragon]

Yes, then in BeginPlay, use Get Actor of Class node to get object reference to the BP in the map.

[elfin abyss]

It worked, thanks

Much appreciated

[trim matrix]

Hey I have a problem after my first Animation is ran and the attack is saved when I press my Left mouse button to execute the othe animation nothing happens here are pictures

[storm vigil]

May I ask regarding how to disable certain inputs? I am playing an animation after using an item so it hides the active UI to show the FPP character animation but I want only those related to movements to be enabled like WASD and mouse look around. Is there a way we can disable the rest of the interaction/keys? Thank you

[fiery swallow]

You're setting your attack number to 0 after you use 0 so 1 will never be hit

it's just gonna be 0 everytime

[trim matrix]

Ok ill set it to 1 and 2 rn

[elfin abyss]

Is there a way to remove all the instanced meshes from an actor?

[fiery swallow]

https://gyazo.com/b60f92cda2239d093630b373dd1f66d4

Or you can add a boolean

[trim matrix]

Hey moxie after I finish the second attack now he just keeps doing the second attack only it never resets back to 1/first anim do you have an idea on why

[pine idol]

I want to create a inventory system, where every item is unique. Like items will stack in inventory slots, such as apples, but each apple, could have a different level of freshness, poison, etc. What would be the best way to do this? I don't mind using mysql or the built in save system to do this, I'm just not quite sure how I should go about this, as I know I'll have a ton of different properties for different items.

Just looking for some suggestions. 🙂

[fiery swallow]

set the second one to 0

[trim matrix]

k

[fiery swallow]

Do you understand what's going on?

[fiery swallow]

First you need to determine how fast the apples last before becoming rotten

[trim matrix]

I seem to be getting consistent frame rate drops in the editor and in game every 5 sec or so. I looked it up and someone suggested to change the input pooling settings in the .ini file but before I try changing it, i was just wondering what it will actually do?

[fiery swallow]

You can do that with a timer, a day cycle, it can randomly go bad, etc. You'll need a integer that holds the number of fresh and bad apples you have

[fiery swallow]

I would open a new project and see if you're getting frame drops there too

[trim matrix]

It looks like i am getting it in both projects. so its got something to do with my computer.

[fiery swallow]

You can try setting the graphics to minimal, like PS1 graphics, if the frame drop keeps happening then yeah it's your computer and not the engine

[trim matrix]

I think my graphics card is overheating but ill try that as well

[trim matrix]

Um not really Not matter what number combination I put in it continuously plays one of the anims

[fiery swallow]

So you press it once and it just keeps on looping?

[elfin mauve]

i want to jump while crouching but animation dont want. what should i do

[trim matrix]

no like I press it and for example if i press it again itll only keep doing the second or first anim

[fiery swallow]

It's likely that your delay is not long enough, try to use launch character instead

Your jump animation will automatically play when it's ready, assuming you are using "isInAir?" Boolean in AnimBP

[fiery swallow]

https://gyazo.com/909e0c26334a76b1b101044e28a24b68

You have 0 and you have 1

Switch on int will output whatever Attack number is

so if attack number is 1, it will always output the second animation

[trim matrix]

Ok I see what you mean now I will test my possible solutions now

[obtuse plinth]

Hi,
I want to set the visibility of static meshes with tags, but nothing is happening:

[fiery swallow]

https://gyazo.com/d05857ef40d772dbe0cc467505742006

Your problem is that set visibility only works on scene components, without casting it to a scene component it won't work
2. I don't know why you're able to connect an array to a single target. Didn't know that was possible

[blazing delta]

hello,
has anyone seen a timer video on youtube that uses timespan variables?

[lunar holly]

Where should I put the functions which keeps track of the levels? I have an array of levels that I use to play the levels in a specific order. If the player has completed one level the game loads the next level. One problem I have is that the function is written on the my custom "GameMode" class, which makes so I can not access the function if I am using another "GameMode" class. For example when I am in my MainMenu level I'm using another "GameMode" class. Where should I put the functions which keeps track of the levels?

[obtuse plinth]

Thx, but I get a Note, that I already have a scene component and I can still set no visibility.

[lunar holly]

@trim matrix Okey thanks. I can try with game instance, because I don't know c++

[fiery swallow]

It means you don't need to cast it because it already inherits the scene component class, so that means it will always cast successfully, so you can remove it

Connect Array Element straight to visibility

[olive sedge]

https://i.imgur.com/eQf6iby.png

Can anyone explain to me what the rotation values are for?

[obtuse plinth]

Somehow it stops within the last loop. Also checked the spelling of the tags.

[fiery swallow]

Then theirs no components with whatever tag you typed in

[obtuse plinth]

In the Outliner they are "static mesh components (inherited)" and got tags

[fiery swallow]

Did you accidentally put any spaces in the tag or something?

I just tried this and it worked for me

[obtuse plinth]

No. Copy and pasted it. Maybe the issue is, that the meshes are parented/linked to the default scene root component?

[fiery swallow]

Probably, you could just set up one custom event that will set the visibility of the parent

Hey guys! What's the best way in multiplayer to bind a UMG nameplate to each player ?

[fiery swallow]

Widget component inside of the actor bp

[dusky harness]

So i have InputAction event on R key that works both for weapon reloading and level restarting. My issue is that when character respawns he immediately starts reloading. How can i avoid that?

[devout geyser]

@dusky harness Use a branch maybe? | Can reload? True \ False | True -> Reload | False -> "Can't reload magazine full"

[dusky harness]

Well yes, it makes sense. But when respawning character saves it's current ammo variable so there easily might be a case when character respawns + able to reload

[fiery swallow]

Upload a picture of the line

[devout geyser]

@dusky harness Is valid node? maybe

[dusky harness]

Valid what?

[devout geyser]

it will check if the character is valid (exists) if so it will go with true else false

[dusky harness]

Welp. Player Character is always valid. It never deletes him. Just loads all saved data in it

[devout geyser]

The respawn event, right after that you can tick the can reload node to True,

[dusky harness]

Yea. CanReload boolean might the most simple solution

[obtuse plinth]

No, got nothing to do with parented objects. Tried it with a static mesh as root (UE4 2.62), same issue.

[fiery swallow]

Did you insert skeletal mesh or static mesh?

You'll need to insert the correct component type

I believe yours are static meshes but I dont know. You'll have to click on them and see

[obtuse plinth]

My class (from get all class) is "static mesh actor" and the component Class is "Static Mesh Component"

[fiery swallow]

If the walls are static meshes then you need to select that in the class option

Get components by tag

[shadow saddle]

can u launch chara during the animation?

[icy dragon]

As in propel the character upwards?

[shadow saddle]

yes

any form

i added anim notify

so what next frame does is plunge atk

but it doesnt push my chara forward

launch my chara forward i mean

[icy dragon]

Yes, either using root motion or add impulse.

[shadow saddle]

only Z axis ?

[icy dragon]

All 3 axis if you want to.

[shadow saddle]

but my chara when doing the anim wont launch

oh nvm it seems that if rm is on

this wont happen

tq

[obtuse plinth]

In the component class, you can only choose "static mesh comp" or "scene comp" without errors - both do nothing. When I delet the last loop I can at least print a string, but no change in the visibility. Maybe a bug?

[dusk ether]

Hey guys im recieving an error on my bp setup

I have setup a system whenever i overlap a sphere collision it retrieves a name variable that is set in my parent ai

then in the children bp which are these cats

i have named the name variable cat

So then in the UI widget i get a reference to the parent and get the name and plug into the bind text

It works well but when one ai dies

then it gives me a pending kill error

I was wondering how can i make it see them as individuals so i can retrieve data from each individual cat not making them rely on one

so if one dies then it doesnt affect my whole bp setup

[elfin abyss]

In an actor, i'm using a box collision and from that i get the extents and divide them by the size of the mesh to get how many of the mesh i can fit inside the box. From there i just place an instanced mesh at the coordinates its supposed to be in order to fill the box collision(for now). Is there a way to remove all the instanced meshes inside the box collision or, even better, remove instanced meshes based on coordinates?

[frozen needle]

I've been trying to solve it for hours and I can't figure out what's wrong
I have a door that should unlock after certain dialogue with the character, then behind that door I save the game
All my variables are saving except the last one that says if door is locked or unlocked, and after I load the game this variable is false again
Here's the blueprint of the character that I need to talk to

this is after that line that opens the door

the door itself

variables I'm saving

and variables I'm loading

I check this "foyer unlocked" on loading the game and it says false

and I can't figure out why this variable isn't saving

all the others are saving and loading just fine

how to play a sound that follows an actor as it moves

[icy dragon]

Spawn Sound Attached

[trim matrix]

i get no sound at all from this

[icy dragon]

You need to have a component to be attached on (that Attach to Component input)

The location input is largely for relative offset to the component that the sound is attached on.

[pine idol]

Yes, I know that I can simply add a property to every single item, such as apples having a freshness variable. But let's say I have a gun, and I need them all to have unique serial numbers too. The gun doesn't need the freshness variable. I'm trying to see if there's a good way to create meta data for items without every item possessing every single possible variable that might exist.

[dry pewter]

Hello everyone, i have a widget with 100-ish text blocks, i need to do a for each loop with those, how can i get a reference to the 100 things?

[odd plume]

Make an array?

[dry pewter]

Yeah, but how do i get the text blocks in the array?

On the event graph i can get the images in the widget but not the text blocks

[odd plume]

You would add them to an array when wherever they are. Kinda Like this

[dry pewter]

But how can i get reference to the text blocks? they don't appear on my event graph

[odd plume]

Cast from the class they are in

So lets say they are in BP_GameMode, cast from there

[dry pewter]

They're in the widget blueprint where i intend to make the loop

Tought i don't need to cast to the self class?

[odd plume]

Can you share your screen in Programmer Parlor?

Aye let me see

[icy dragon]

You could also get children from the parent container of thr 100 text blocks

[twilit heath]

@dry pewter select your textblock in the designer, and top right, above the details panel, check IsVariable

[dry pewter]

Yeah, made that with the help of @odd plume , thanks 😄

[dry pewter]

Tried but couldn't figure it out

Also as the parent container, in this case the canvas panel contains other like 10 elements, this solution fitted better

[odd plume]

👍

[gentle urchin]

Sounds weird that the parent is canvas for 100 text blocks but ok

[dry pewter]

Maybe i get it wrong but this is the hierarchy

[gentle urchin]

Yuppyupp. Im surprised you added those manually in the first place 😅

[dry pewter]

I tried to "spawn" them but idn't find a way of doing so

Now that i added them manually i had to make more work yes, but the blueprint will be much much simpler

quick question -- when it comes to 3D audio, what actually is receiving the sound -- player camera or pawn or something else?

[verbal bobcat]

How do I cast to a pawn that is not controlled by the player?

I need an object for the cast @trim matrix

and idk what that object is if that pawn is not controlled by the player

[dawn gazelle]

Casting is only meant as a means of making a less specific reference more specific so you can access the variables and functions of the more specific reference. For example, you can have an actor reference and cast to "Drone" so that you can access those variables you want.

What you need is a reference to the specific Drone object that you're looking to get those values off of.

[trim shuttle]

Quick question does anyone know if a layer blend node will work with a break material attributes to the final master material output

[verbal bobcat]

Ok good to know ,but how exactly do you do it so I cast only to that specific Drone object?

[dawn gazelle]

You need a reference to that drone object.

[verbal bobcat]

just a drone reference? like the variable one

[dawn gazelle]

You can create a variable but it needs to be populated with the reference to the drone that you're trying to pull these stats off of.

[full hare]

Heya its me again so i am making a tower defense and i need to spawn a wall but i also need the nav mesh to update when the wall spawns that would be fairly easy but how do i update nav mesh (setting nav mesh to dynamical breaks the ai they basically move in the correct direction but twitch to sides) is it possible any ideas?

[earnest tangle]

dynamic should work.. just make sure your actors that aren't supposed to affect navigation have the "affect navigation" checkbox turned off

that's most likely the cause of the weird navigation problems

since that checkbox defaults to on for most things

[full hare]

they bug out even if they walk fowards thats what makes it weird and it only happens if i set dynamic even if i dont add anything at all with static they walk foward to end point with dynamic they walk there but they keep twitching even if i dont spawn anything else

randomly turning around and etc (the goal is right infront of them they are standing almost beside it

could it be because they themselves make a hole in nav mesh ? (i never noticed it until i used the dynamic so it would check out)

its fixed 😄 thank you so much it turns out i had a tiny cube of scale less than 0.01 in all of them to act as like a center point for hitbox and i forgot to turn off collisions

also i am using on component begin overlap to target enemies the problem is It always targets the last enemy to enter range any idea how to make the turret attack the first one ? or to attack the one thats closest to the end (The map isnt a straight line so if its possible that the closest to end calculates distance using nav mesh and not just a line)

[fiery lark]

Is there any way to fire an event when a boolean changes?

I have an animal I sacrifice and when I sacrifice it I want the horde mode to start, but I can't figure out a way to do that

[dawn gazelle]

Fire the event instead of changing the boolean.

[fiery lark]

Damn it im an idiot

Thanks bro

[dry pewter]

I think on turret defense games the defenses attack the closest enemy in a straight line, going above walls and holes?

[full hare]

they attack enemy thats closest to the end (counting by the path)

[dry pewter]

In such case, use get overlapping actors to have an array of every enemy in range, then make a for each loop and have some math to calculate which one is the closest

[full hare]

closest to the end or to itself ?

[sonic silo]

Wtf are this nodes

[dry pewter]

What do you want the turret to attack? the closest to the turret or the one further ahead?

[full hare]

the one thats closest to the end but it needs to be calculated by the distance needed to get there

not just a straight line since 1 sec i show you

the turns are the problems since if turret checks distance to the end it will think the one where i said -further away- is well not first even though its closer to the end than the -closer-

[dawn gazelle]

Make literal float is exactly what it says it is - you're just creating a node that has a float value defined in it that isn't stored as a variable.

Max will select the highest value out of the inputs.

Normalize converts a vector's x y z values to a range between 0 and 1, where the highest value input is considered 1.

[dry pewter]

I understand that the map changes during gameplay and the route might not always be the same, right?

[full hare]

yep the black line under the start is the only place u can rn build a wall

[dry pewter]

I don't know if there's a way of calculating the distance needed to traverse that but i can think of a workaround

[sonic silo]

Thanks for help

[dawn gazelle]

Negate Vector is literally the negative version of the vector (so each axis is multiplied -1 basically)
Vector Length Squared is basically XX + YY + Z*Z;
Ceil rounds a float up to the next nearest integer (-1.6 becomes -1, 1.6 becomes 2)

@full hare What i think, make a grid on the ground, with invisible no-collision actors that work as "checkpoints". now make another invisible AI actor that has to walk the same route the enemies would, but much faster, like, isntantly, and have that invisible enemy give an increasing number to each "checkpoint" it touches. Now you have the checkpoints every enemy will need to traverse where the highest numbered is the closest to the finish line. from there, you can check every checkpoint to see if there's an enemy above it's location, start counting from the last numered one to the lowest and attack then... i don't know if i am clear

[full hare]

maybe i get it 😄 i think

also the invisible enemy that increases their number walks there only once right ?

[dry pewter]

Once everytime the map changes so it cna find the route

[dawn gazelle]

COSd is Cos(PI/(180.f) * InputFloat). Has to do with trigonometry.

[full hare]

phew that will be a tough one to do especially with me being a beginner

[dawn gazelle]

Dot is a bit more complex than I'm willing to explain... https://mathworld.wolfram.com/DotProduct.html

[dry pewter]

Some things on UE can be much simpler than they sound on paper 🙂

Other things might be much harder tho...

[sonic silo]

@dawn gazelle thanks for help

[full hare]

well i will maybe try it later (i am running low on time deadline soon so i have to finish up the rest first and then i will try to do it haha thank you for help lets hope )

[cinder smelt]

i'm trying to play a sequence and swap to a character after but the camera seems to switch back to the viewport camera and not the one attached to the character controller

it switches properly on the keypress though

[dry pewter]

Try this: before the posses node make a get player pawn and unposses

[cinder smelt]

thanks @dry pewter

[unreal token]

am i asking too much for a noob?

Vampire game: how would i go about creating a very customized day / night cycle, such that day is only 10% of the time and night is 90% of the time.

is this too advanced for me?

someone told me i need to be a full on programmer for that

[icy dragon]

Not really.
You can pull it off in BP.

[dusky harness]

How can i delete all particles on level from blueprint?

[icy dragon]

Get All Actors From Class -> For Each -> Destroy Actor

[dusky harness]

Well, particles are not actors. They're just spawned emitters so i can not delete them that way

[unreal token]

and for me?

timeline? or is that just for animation

[cobalt slate]

Hey guys. i haven't found an answer to this online so i thought i would ask on here. Is there a way to enable/disable something in the project settings/defaultengine .ini through Blueprint? Specifically, i want the option in my menu to turn raytracing on or off. I want to be able to trigger r.raytracing = true/false in the ini, and then prompt the player for a restart, all from BP if that's possible?

[fiery lark]

Hi guys, I'm doing an overlap and I want to make a special event happen ONLY when it overlaps the player character, not when it overlaps the enemies. How could I do this?

[cobalt slate]

i'm guessing out of the overlap "other actor" it's casting to the enemy BP?

@fiery lark

[fiery lark]

I figured it out right after I posted it lmao, but it doesn't cast to it it just plays a sound on where it overlaps

I fixed it by setting a branch, and making overlap actor == player char

[cobalt slate]

You can do it that way or you can have it cast to the player BP to verify that it's the player if it is, then execute command, and on the "cast failed" pin, you could have it cast to and enemy BP to see if it's them, then execute it's code.

if both fail, then it does nothing

this is techinically better in case UE decides to change how the player name is displayed on the == in a package build. I've had that happen before

[fiery lark]

I hope that doesn't happen in a packaged build lmao

Also, do you know how to clear a timer by event?

[cobalt slate]

yes. one sec

just make in event timer a variable then you have all kinds of options for it. you can even pause and unpause it.

and yes, in a package build, UE names things slightly different when called. For instance, in the editor, if i were to print "get object name" it would say BP_Hero. In a package build it would print BP_Hero2736538294

i believe it does this for unique instance for multiplayer

[dawn gazelle]

If you're doing a straight comparison of two objects, I'm pretty sure it would be comparing them by pointer reference, not by the display name of the object.

[cobalt slate]

exactly what i'm saying. that's why i do a cast to off of an overlap as shown above, vs getting an object name. I've seen lots of people make this mistake and even i made it back when i didn't know.

[spark steppe]

there's a node which can run console commands, maybe that helps?

so you would save a bool for raytracing in your custom config and run the console command on start to turn it on/off

[cobalt slate]

But how do I access the custom config? That’s what’s getting me. Console commands only seem to work in the engine will the editor is running. Once you exit out of the editor, those commands default back to what’s in the config file.

[spark steppe]

for my project i just made a custom save game which contains the config variables

and yea, you would need to run the console command everytime you start the game, that could be done in custom game instance in the Init Event

i'm just not sure if it will work for raytracing, but it's probably worth to try

[cobalt slate]

Okay. I’ll dig around there

Thanks for the idea!

[stuck fossil]

Im not sure if this is the right place to ask about material blueprints, but I was wondering if anyone knew a way to set up a material where only part of it is emissive? For example if I wanted to make a building that was all one texture, if I had say a separate image file with just the insides of the windows, could I make my material emissive on only those sections?

[icy dragon]

#graphics is also for material

But in regards to your question, yes, you can have a part of your texture emissive, and multiply it. Though extra workaround is also needed, because you have to mask away potential compression artifacts.

[stuck fossil]

Okay cool, thanks for pointing me in the right direction! I'll fiddle around with it some and see what I can come up with

[amber nova]

is there someway for a child actor to be parented by a different parent actor . because my dumb brain been working on an AI_npc_Enemy that is a child actor of the player actor blueprint . the thing is , i wanna replace all the attack animations and such but if i do that , it will affect my player character too cause i put all the attacking animations in the player parent actor blueprint . so i was wondering , if i just duplicate the parent actor , is there a way for me to reparent the child actor to the duplicated parent actor so i can change stuff in there instead

[trim matrix]

Hey I have a question would I make the hurt boxes first or the health system first

[dry pewter]

Now, you need to double click a blueprint to open up the editor, and from there you click File >> Reparent Blueprint

This is taken from answershub from a topic where the user deleted the parent class, try and see if you can work this

[amber nova]

thanks it works

[ashen basin]

How do i grab interface output data?

i have set input data in another blueprint and i want the output in seperate bp

[dawn gazelle]

Implement the interface and use the provided pins?

[ashen basin]

says i need to add input

[dawn gazelle]

So if you have it set up like this on your interface, when you implement it in another BP, it would have "interactor" as the output from the interface node.

If you have it set up like this, then it would return the value to the calling BP.

[ashen basin]

yeah i dont have the event as a option

removed the output and was able to get the event

though doesn't work out

[surreal peak]

With the output you have to check the interface section on the left of your bp

It will list the interface function there

Usually rightclick and then implement function does the trick

[ashen basin]

you saying add interface in the class settings?

than on left under interfaces?

[sonic pine]

Hiho i did this in the Playercontroller, but the errors are the same ^^

[dawn gazelle]

I think this might be what you want to do? The hit results seem to return several hits of the same actor on my end, and can hit multiple actors, but it projects forward from the point on the screen where you're clicking. Just make sure your trace channels are ones that overlap the actors you're concerned about.

[white crypt]

@sonic pine im pretty sure if you sent an image of your code, it wouldnt look the same as mine

so try comparing them again and read Cedric's networking guide

[sonic pine]

My Problem is the Login

[surreal peak]

Yop

[ashen basin]

yeah done that

[white crypt]

@sonic pine i've only helped you on how to add a widget for a local controller, don't know anything about your login issues

[sonic pine]

This code is in the game instance. I think that it has to be in the gameinstance, because the login menu has to be loaded before the actual game is loaded.
Login-> Server selection -> Character selection -> start game

I know ^^

[violet wagon]

My camera rotates with the player model, but i want the camera to rotate while the player model stays still. any solution?

[surreal peak]

Make your camera use control rotation and the character not use it

[azure sparrow]

I am trying to access the rotation of the sun, i already have accessed the direcional light (sun for me) and trying to access the y axis value of the lights rotation how can i do that?

i dont think i am even doing it right

[icy dragon]

Just split the Return Value.

Right click -> Split Struct Pin

[dawn gazelle]

This is why you need to change the collision profiles so that any intended targets of this trace are set to overlap and any not required are set to ignore, with only possibly the ground set to block.

[hushed flame]

If I'm having 2 different Blueprint actors (like BP_Foo and BP_Boo) which only has InstancedStaticMeshComponent as their root, will they be good performance wise?

[surreal peak]

Ehm

I guess? :D

You should probably just use it and only worry about optimization once you need to

And then use the profiler/unreal insights to check what is actually expensive

[delicate folio]

hi so about this question that i asked and was told it is possible , the easiest way i can think of doing this is obviously with trigger boxes and overlap events but this wont be as accurate to the landscape so i was wondering if theres a way to directly reference the layers from the landscape in order to slow the player down once they overlap with / walk onto one of the specific layers

[hushed flame]

Your Landscape can have Physical Materials applied on them and when the player is walking, trace down to find which physical material is being hit. If it is your forest physics material, slow down the player

[hushed flame]

Yeah I think I'll do that 🙂. What if I place multiple instances of same Blueprint (like 100's of BP_Foo)

[surreal peak]

You will have to find out :P

Hey guys, go another big wall in front of me right now. So i'm trying to do a common dialog system with ST and DB.

thank you very much i have managed to get it working as someone who doesnt do much with landscapes i didnt even know about the physical material thing but that is really useful thank you very much

[proud sable]

Is there a way I can access a variable from the level blueprint in other blueprints? I've read the documentation on casting and I don't fully understand it. I have a character switching node tree in the level bp that cycles between 3 characters and I need to reference which character is active in another bp. I'm pretty new to UE4 so this is a bit of a struggle for me, sorry for the basic question

[hushed flame]

I wouldn't suggest using Level Blueprint at all. Instead you should use Player Controller to switch between your characters. That way you can always use GetPawn to get the active character since Player Controller can only possess one pawn at a time.

[proud sable]

Thanks, I'll give that a shot instead. I was adapting some methods from a tutorial I had seen and they used the level blueprint for some reason. I would still need to communicate the GetPawn result to my HUD blueprint though, would that be a job for Cast To or am I going down the wrong rabbithole?

[hushed flame]

Is your game multiplayer?

[proud sable]

Single player

[hushed flame]

Then in your HUD Blueprint add a Get Player Controller node and then from it add GetPawn node.

[twilit heath]

HUD has GetOwningPlayerController/Pawn

that works just as well in SP/MP

[proud sable]

Sorry yeah I confused it with something else, thanks! That gets the active pawn, how would I get the individual non-controlled ones? I can do this in the level blueprint but not in the HUD one which is why I've been wondering how to cast to other blueprints

[hushed flame]

Your non-controlled ones, are they dynamically spawned at runtime or you placed them in level?

[proud sable]

They're placed in the level yeah

[hushed flame]

Then in your Player Controller Blueprint in Event BeginPlay node create a Get All Actors of Class node with class set to your pawn. Save the result to an array and you can use it to get non-controlled pawns

[proud sable]

Thank you 😊

[ashen basin]

Speaking of communication between blueprints

Can some one send me a demo of interface

Need array from one bp on another thanks

Either dm me or tag me as ill checking back tomorrow appreciate the help

[woven kelp]

How can I "lock in" the value of this array?

when I print it I get a different result each time

The random float node is being evaluated each time the array is accessed

[dawn gazelle]

Create a float array variable and set it to the value of the array you're making.

[woven kelp]

thanks! I ended up making a macro that just sets a local variable and then returns it

[sand bloom]

Hmm does anyone know a good way to handle rotation, I got left and right rotation of something to work fine with a lerp rotator and timeline, but the issue is when I want to do up and down rotation it doesn't work

i'm assuming because i'm using another timeline and lerp rotator

and it leaves the other values 0 instead of ignoring them and only using the values i want to change

the top part is for up and down rotation

should i try and use break rotator

im not sure how to do it

as you can see up and down works fine

but it resets when using left right

does anyone know of a good way to do this?

like if I split it I do get separate axis which is great but they are floats..

like how do I use a float to set rotation

🤔

ohh ill give that a try

omg I got it to work thank you so much, I didn't know that node existed

I used make rotator because it seemed the easiest route haha

ah that's good to know 😄 thanks

i'll have to keep that in mind for the future

It's not something that would constantly happen, it's just a cannon object that won't get used much but that's fair yeah. If this was something constantly being used like a character i'd probably have to make it less wasteful like you said

ah yeah true haha

I'm just not very good at blueprints and this works, i'm not quite sure how to get it to become one line

[surreal siren]

If I'm trying to cast a variable what is the object input for? The cast node is still a mystery to me as a beginner. I have a boolean variable in BP1, I need it in BP2 for a branch node condition, but I need the object input for the node to work.

I know it doesn't work but, why isn't this enough to get the value?

[odd nova]

thanks!

[coarse lantern]

When binding events in a loop how can i use the object reference of the element inside the event? Right now it always uses the reference of the last element of the loop

[fluid rose]

Does it print out the last element of the loop several times or only once?

[coarse lantern]

It's printed once the OnClick event is fired but it's always using the Button reference of the last element of the looped array

[formal prairie]

hello ! i'm starting to work with gameplay tags now, the issue is that it dosen't work. i've set up my tags, set it inside my actor, and ask the other actor tio check the tag of the actor that entered the collsion with i, but it dosen't react... the collsions are working i checked with prints. did i forgot something ?

[pale orbit]

What do u guys think is the easiest way to spawn a projectile that moves in the air as i move the camera

Are you going for a laser guided missile effect?

If he sends the projectile by pressing X, he also wants to be able to send it left by holding X and moving his mouse left, even if a wall's blocking a raytrace from the player to where the projectile is

[trim matrix]

Hi everyone, i am using a platformer template to prototype something so i'm trying to add an health blueprint when the character "touch" some spikes, the spikes are already animated within the template so i have added health variables ecc now i'm watching a tutorial wich show that i should attach the event actorbeingoverlap to the "takedamage" class i have created

but i have already an event beginplay node

i'm trying to figure out what should i do

the actor is called BP_Spikes but inside of them there are other staticmesh that are currently the arrows

[true marsh]

The cast node is to communicate with other blueprints. The object is the target of the cast and the cast type is a compatible actor class.

Based on your screen shot you would need to save the character as a variable than connect it to the object input.

[unkempt musk]

@trim matrix Maybe something like this?

[fluid rose]

Is there a variable type for any keyboard key? I'm trying to create a map using keyboard keys as the key and want to listen to any keyboard press (found the "Any Key" event) and see if any of them are within the map
Key -> listen to Any Key, thank you regardless

[maiden wadi]

@true marsh Careful with the phrasing, that wording confuses a lot of newer people when learning object control. That is not technically correct. Casting just changes a pointer type. It doesn't actually communicate or do anything. An object that is a character is also a pawn, and an actor and an object because character inherits from those. If this character is passed around as an Actor pointer, you can cast it to Pawn or Character to get access to those variables and functions, but it is still the same object, just treated different. Think of casting nodes as a "Treat as" node.

[zealous spruce]

hey guys! i was wondering if i could get some help?
im trying to make an interface so people can connect to an ip or host from their ip, and i was wondering if anyone here knew how to make it so the input mode is UI only, and make it so that the mouse cursor is visible

i already know that it works i just need these things for quality of life

[unkempt musk]

In your player controller, use these nodes

[zealous spruce]

:0

where do i find that set mouse cursor node

i cant find it

[unkempt musk]

Same place. They only show up in the controller class, or when you drag off one.

[zealous spruce]

aight

i got the nodes

sooooooooooooooooooooooooooo, what now?

[unkempt musk]

When you spawn your widget, after AddToViewport, have those two run immediately after.

[surreal siren]

i made a a jump walk run animation but its like looping very bad. i can sendt ss of blueprints

[zealous cave]

Hello All, I'm following the "How to make Pong in UE4" tutorial that is in the channel pins. I'm on Part 4, "Finalizing Paddle Movement." The problem I'm having is my paddle is continuing halfway into the top while his stops right at the paddles edge. I don't know if over the past 6 years since the video was made that coordinate system has changed. A simple solution would be to adjust the value of when the paddle stops to half the size of the paddle from the limit. But I'd like confirmation that it was a change since his 4.7 vs my 4.26 or if its another reason. Maybe I missed a step. https://youtu.be/u8KOg-IZtQk?t=283

[zealous spruce]

soooooo... my addtoviewport is in the level blueprint, not in the character controller, as this is a thrid person game

[unkempt musk]

I'd recommend moving your logic to a GameMode(better) or GameInstance(best). UE4 has a built in controller associated with all players. But that's not accessible from the level blueprint without additional steps.

[zealous spruce]

this is a bit more complicated then i thought it would be

i was litteraly just following this tutorial https://www.youtube.com/watch?v=1MA9_U3XRZs and he said to do these things so i was like, cool idk how to do this, ill ask some people on this discord

[unkempt musk]

@zealous spruce It does work in level blueprint. My bad.

[zealous spruce]

:00000 Thanks dude! :]

wait now i cant click back into the game

how do i switch back to the game :[[[[[

[nova ledge]

Hello everyone! I'm trying to make it where my flying character can land only above a certain height from the landscape (if I don't do that, when the main capsule component hits the ground and you try to land, you'll be stuck in flying animation). I was going to use line trace by channel once, but it would only get the coordinates of the landscape and not the actual heightmap of it, so I ended up using box collisions. However now that's acting weird. I was using 4.26 before but now I'm using ue5, so I don't expect everything to run smoothly, but I wanted to know if this looks right, or if I should add/subtract something from it. Or is there another way to fix this by somehow using heightmap?

[unkempt musk]

@surreal siren Try clicking this button on your animation sequences and see if that helps. If not, change it back.

[sturdy herald]

Hello!
I try to use a button on widget to rotate something.
When the button is pressed, then the rotation should start to determined direction, and when released, the rotation should stop.
I tried this method, but it only add 1 to the rotation, the loop doesnt work well.
On the link u can check the actor's blueprint and the photo shows the widget.
https://blueprintue.com/blueprint/-nx0sew0/

[unkempt musk]

@sturdy herald Maybe something like this?

[frozen needle]

What could be causing the Cast failure to player character? On the screen I have an object that player hides behind. The object on the right works perfectly, but the copy of that object on the left returns failure of Cast on leave the hiding. What am I missing?

here's the blueprint

It's the same object, but for some reason it doesn't work in that particular spot where the left copy is

So is there a way to check why exactly the cast is failing or something

I found out it's somehow related to the area this object is in because the cast fails on the other blueprint as well IN THIS spot

But I can't figure out why exactly

Because it worked all fine before

[unkempt musk]

Try GetDisplayName of the "OtherActor" and see if that gives any clues.

*Then print it

[sturdy herald]

I need 12 buttons thats works like this, so i thought its better to avoid event tick, but if i cant make this timer thing work, then i dont have choice. Thanks for advice.

[frozen needle]

Thank you

[true quartz]

If I wanted to make a level end when all objects are collected how would I do that?

[unkempt musk]

@sturdy herald There is also a rotating movement actor component. Changing the RotationRate will change the speed. Anything that rotates will have some form of tick to get it to update.

@true quartz collected how? Total number? Specific values with each?

[true quartz]

Yes so I have x amount of each object to collect and when all are collected I want the game to end.

To be specific I have two balls three spacemen and five pieces of laundry that I need to collect for the game 10

For game to end

[sturdy herald]

Thats true. Thanks for answers:)

[unkempt musk]

If all important items are the same BP class (I reccommend), you can use this.

[true quartz]

@unkempt musk it's a game for school in which a character goes and collects all the items and then after doing so is awarded a gold star per set of items. I am trying to figure that out and the finishing the game

Ahh I c

[unkempt musk]

Ahhh... give me another moment then

[true quartz]

Ok ty

[unkempt musk]

It the character I add this. It gets the list of object references to collect...

[true quartz]

Ok

[unkempt musk]

I made a BP_Collectible that can be laid wherever. Once you overlap it, it'll remove itself.

If you want to store individual names in the items, you can add variables for a more specific checklist. But that should be most of the functionality.

[true quartz]

Ok thank you. I didn't know if there would be a way that would work with the HUD or not. I have the collectibles set up and a HUD that displays count. I thought there would be a way that when items in his = 0 trigger game over. And then I figured I could award the star per set of items.

See like this and then I reveal the hidden widget.

[unkempt musk]

You'll have to run a check function after each pickup, or bind to an event, but that's a bit more technical.

[true quartz]

O... Well damn

[unkempt musk]

Computers don't know anything changed unless you tell them

[true quartz]

Yes I just figured I could hide the stars and in hide them upon the count reaching 0 per item set

Then I could make a variable has 3 stars to end game

[proud sable]

Is there a simple way to mark a character as active/possessed with a bool variable in the player controller? I have character A B and C and want to appropriately mark the "Active_A" "Active_B" and "Active_C" bools as true/false when the player is controlling them. I've been pulling my hair out with this, I've tried so many things to get it to work

[snow halo]

halppp. Is my blueprint corrupted or? I can't delete this Timeline comp

[dawn gazelle]

You can test whether or not a pawn is controlled by a player:

[snow halo]

i'm fairly certain it is not in my graphs

When i double click it, it opens the bloody timeline under it which i am actually using

[dawn gazelle]

Right click on it and select "Find References". It'll give you a listing of where it's used and you can double-click on the results to find where it is. Nevermind... doesn't work 😛

[snow halo]

@dawn gazelle ya i did that o course

it's def not in my graphs

Even if it was, i should still be able to delete the comp

No it's def not inheriting a timeline either

it's base class is AActor

[dawn gazelle]

You typically can't delete components this way. If you did it with a mesh component it wouldn't let you delete it directly.

[snow halo]

If i double click it, it opens the timeline under it ScaneTimeline

how weird is that?

[dawn gazelle]

Try typing the name in the search:

[snow halo]

it's like some broken reference

ya i did that too

just renamed it to Timeline_0

[true quartz]

Would that be possible @unkempt musk

[dawn gazelle]

Did you hit the compile button afterwards?

[snow halo]

yup yup o course

tried rebooting the project also

It's gotta be some bug because there's no scenario where i should be double clicking that comp and it opens a different timeline

[trim matrix]

Just checked it out yes it seems like a bug

it happened after I deleted and undo it

[dawn gazelle]

Try searching just for the name of the Timeline.

[trim matrix]

I do

yeah

it found

that way tho

odd

[proud sable]

How would I use that to toggle the appropriate boolean though? I'd show what I have right now but I feel like I'd just get laughed at lol.

[dawn gazelle]

Whenever you need to check if the pawn is controlled by a player you can call that function and it'll tell you if it is controlled by a player or not.

[unkempt musk]

@true quartz Something like this?

[true quartz]

Yes

I did that and it didn't work. Hmm

[unkempt musk]

What does it do?

[dawn gazelle]

So what you can do for your test, is just check by reference of the character that you want to test. This boolean will be set true/false automatically based upon whether or not the character is possessed by a player.

[proud sable]

Thanks, I had something similar but I think it's an issue with my array. I'm not in the level bp so I can't reference the pawn directly, I'll give that setup a shot soon and see if I can figure it out

[dawn gazelle]

What BP are you in?

[proud sable]

I'm in the player controller blueprint, but I'm trying to cast from the HUD blueprint

[untold dust]

Hello everyone, newbie question here, I created a script that load widget directly without passing thru a Hud and for myltiplayer I use the function get all widget of class and I select the widget I use, but I try to implement my code to a hud, but my function get all widget of class return nothing because the widget is in the hud... someone know how to get all particuliar widget in the hud ?

[dawn gazelle]

You can get a reference to the specific character you're controlling, in which case you wouldn't need to test which pawn the player is controlling. The Get Player Character node is fine to use single player, not great to use in multiplayer.

[untold dust]

It's a chat BP that I made and I loop from all the player widget to send the text

but in the hud can't find the widget

[true quartz]

@unkempt musk nothing

@dawn gazelle i found out how to reproduce the bug

So if you try and copy some BP logic that contains a timeline to another BP, but a custom function you are trying to copy does not exist in the destination, you will then get a message asking you what u want to do about that... if you then hit cancel, nothing gets copied EXCEPT that bunk timeline component variable (with no actual timeline in the destination graph)

[dawn gazelle]

oof

[snow halo]

so you are then perma screwed w a corrupt BP or at least that stupid variable

is there a way to change a game sessions name?

i have on overlapp begin on a missile , i check owener of other actor, it say "pc_gameplay" if its the host and "pc_gameplay1" for client 1 and so on. wich is great. but i als want to check owner of the missile itself, if i use self reference on get owner i get "bp_character" instead of "pc_gameplay" how to check owner of the missile itself?

[dawn gazelle]

I'm going to assume that pc_gameplay is actually your player controller. I imagine you're spawning your missile from your character and setting the owner there (with a reference to self) which means the owner would be the bp_character.

That said, when dealing with multiplayer, owner should be the character, not player controller as clients aren't aware of other player controllers so checking for owner when it's set to a player controller may return null references on other clients.

Same with your overlaps - you don't want to check the owner of "other actor" if the owner is a player controller. The "other actor" reference itself should be sufficient.

I'm going out on a limb here, but I think you may be trying to figure out if your missile is hitting the person who fired it and if you want to make sure your missile isn't hitting the owner, then all you would need to do is check if "other actor" is != the owner of "missile".

exactly, how to check owner of "missile "

[keen prairie]

is there a way to swap out textures in a material graph using a blueprint? or change a const3vector value?

[dark crow]

Dynamic Material Instance?

[spark steppe]

yes, if you create a dynamic material instance you can change texture/scalar/vector values

[dawn gazelle]

That would be "Get Owner". To set the owner when spawning it, the spawn actor node has an option to set the owner, though it's hidden unless you click the little triangle at the bottom. If nothing is set there, then no owner is assigned it looks like.

[keen prairie]

thank you very much! i'll look into this :)

thank you

Hi i wanted to know if there was a better way of Un Crouch to sprint without having to use a delay basically i have a crouch BP that uses a timeline to lerp between the normal capsule half height to the crouch height and the only way i made this work was delaying the 0.5 or else the sprint code isn't ran?

[dapper dagger]

am I missing something?

was just watching https://youtu.be/K0ENnLV19Cw?t=3116 and Mr. Allen showed this little example but his pins wouldn't connect and he blew past it.. so I decided to try for myself and yeah, needs that cast which kinda defeats the purpose if I'm thinking about it correctly

[ember veldt]

It depends. Soft references for something like meshes/sounds can be useful. Soft referencing things like data assets and casting it to its class only makes a hard reference to the base class, not the individual assets

For example i can have a dat asset of Item that stores a string, mesh, icon and sound. The mesh, icon and sound are soft references. When an item spawns it takes the soft reference of the asset, loads it, then loads the dependencies only if they're necessary. For example only the icon needs to be loaded if its in the inventory. If it's then put in the world it will load the mesh.

I can have 500 items with different meshes and icons and sounds, and none of them will be loaded until they are actually instantiated, and even then they only load the specific necessary assets instead of loading everything involved with it

Casting to actor class in this case does not create a hard reference as actor will already be loaded and is not a specific different class.

Hey guys!! I'm looking at creating a choose your own adventure game which practically amounts to creating a binary tree via blueprints. I had a look at structs, and while they're what I need, they seem incredibly bulky and unmaintainable. What are some of the better ways I could go about creating a binary tree data structure so that it's maintainable into development?

I've tossed up making a class object but that kind of has the same issue - authoring and managing the binary tree. I also considered using something like JSON or XML but it seems there's only C++ versions of those tools available.

[severe turret]

@jolly oriole creating a Graph system is the way I've seen it done best. I'd check out some of the free plugins like Not Yet Dialog Plugin. Its a good example

[zenith escarp]

I've done it with structs and data tables before, but it was not the most user-friendly thing. For that kind of stuff now I tend to use a free plugin called 'GenericGraph' which works better for trees/graphs and is blueprint accessible.
