blueprint

[red berry]

I'm copying tarkov's inventory system. So a backpack can have multiple groups of grids in them. So a backpack with a 1x2, 2x2, 1x2 would have 3 of these StorageTileParts. If I try to add a 2x2 object, it will try to add it in the 1st which will fail, but then should succeed in the second group.

StorageTilePart is basically row, column and an array of ItemDataObjects. That array is the one that gets started as a 2x2 (4 item array), but then gets to a 1 item array for some reason (what im trying to fix).
Edit: I only have 1 compartment in my backpack for now, its just a 2x2. Items larger than that don't fit in which is expected.

[dark drum]

If you pull from the root component and search for collision, it should show you the right node.

[dark drum]

So your trying to make a spacial grid based inventory system?

[red berry]

yes

[upper badger]

All I'm getting by pulling from Root Component is Get Component Bounds tho (plus some landscape stuff?)

[red berry]

I haven't checked if the array gets reset upon me picking up. So I will try that now. If I pickup the bag, is the array reset already? Or is it still 2x2? I have to know

[echo storm]

Can I disable input for a single instance of a Blueprint Class instead of the entire Blueprint Class?

[dark drum]

That would depend on how you pickup the bag.

In all honesty though, there's a few issues with how your going about things. The for each loop on the first screenshot is pointless with how you have the function setup for resizing the inventory. In addition to this, you change the inventory size on begin play but you should be setting the inventory sizes in component defaults when you add it to an item. (your backpack in this case)

I'm still not convinced the resizing is working, adding to this, why do you even need to resize 'ItemDataObjects' array?

[frosty heron]

yes but you should never have any input on seperate classes to begin with

Keep your input in your player controller/character

[dark drum]

Well this would depend on what your doing. I would say this is a soft rule but generally this is good advise. However, if your using enhanced inputs, this isn't much of an issue if you using seperate mappings for other actors.

[dark drum]

sorry, take the root component and cast to primative component, this will give you the nodes for the collision.

[upper badger]

great, I can move now with the item attached to the character - Thanks!

[red berry]

I managed to find where my code is bugging but its still not fixed. Does breaking a struct passed in as an argument to a function create a local copy?

[tawdry surge]

Unless it's pass by reference yes
However structs (like most things in BP) are copies anyway.

[red berry]

So if you have a struct with an array, then its impossible to alter that array? Every time you try to reference that struct or break it, its a copy?
Is there any way to break a struct without making a copy?
Seems like I have to redo some of my code to use Objects instead of Structs, because blueprint structs don't work well with arrays.

[frosty heron]

Try splitting instead breaking? Iirc breaking gets a copy

[red berry]

Won't let me split a struct

[versed sun]

Nothing can be plugged into the pin you want to split

[frosty heron]

I'm not in editor, is there no get by ref?

[red berry]

Get only seems to work on an array of structs, which you can then split. But if you have a single struct on its own, it wont work.
Edit: Im wrong. I created a local variable of type struct and you can split it.
Edit2: I'm giving up on structs. They dont play nicely with arrays at all, even if I removed all the breaks and use splitting. Passing a struct into a function just makes a copy whether you pass a ref or not.

Hello, I have a map with 3 different lighting levels and i'm trying to make the map load with a specific lighting level enabled when I select that specific lighting in the menu and load the map, but so far I can't seem to get the lighting to stream in properly.

^the beginning

It should work from what I can see but it doesnt load the lighting.

The lighting levels have been properly added to the map in the levels window, and the streaming mode is set to blueprint.

[frosty heron]

how to live without struct?

Get by ref (Diamond shaped one)

passing an array to function always pass it as reference by default

[marble tusk]

Breaking definitely doesn't get a copy because this works and sets the transforms in the source struct

Also a common issue people have with arrays of structures is in not knowing the engine's "For Each Loop" macro gets a copy, and you can just double click it to open it and verify. Then you can copy it to your own macro library and swap out the get (copy) with a get (ref) and use that instead

[lunar sleet]

Get makes a copy, the normal one

[red berry]

You're a godsend! Thank you so much! I was about to refactor my code using objects instead of structs because I couldn't figure it out. But checking pass by reference in my functions fixed it for me!
Edit: @marble tusk I can attest that breaking doesn't get a copy too. I tried it on my code and the struct's array can still be edited perfectly when passed by ref.
@frosty heron I'm not sure that arrays are passed by ref as default, didn't work for me I think. I had to manually check it.
Edit 2: Actually arrays are passed by ref as default. You can't uncheck it.

[echo storm]

What is the best way to change the item a character is holding? Add it as a component to the blueprint and then use the "activate/deactivate component" nodes?

[frosty heron]

Yup , it greyed out the option

[west gate]

I have a requirement where in, when the game is started, there should be a certain movement (as if player is walking some distance) and then the game will start.

I understand I will have to write a blue print event on game start and adjust the position of the player capsule component.

Please suggest me how to get this done.

But I am not able to implement this as “move component to” functionality is available only for static mesh.

In short I want to mimic the joystick navigation for some 10 seconds initially

[lunar sleet]

You’ll need to possess it with an AI controller and use an AIMoveTo

[torpid juniper]

Hey, i'm trying to still get my head around how data assets work and how and when i will be able to use them and when i need to use actors with components or such. If i have a data asset class (primary data asset) which has a function for storage containers like chests and stuff that has an on interact which will open the interface for that chest. What is the best way to do that? Am i able to do it all through the data assets? Or will i need to use the inventory component and just have the data asset function deal for opening the widget and pointing it at the chest i am clicking on and then stuff will be redirected to the component?

[winged zephyr]

How do I allow a widget to have childeren

[dark drum]

If its just a straight line, just add movement input (the same as you would with inputs). You'll need it to be called each tick until you want it to stop.

[worldly breach]

Hey, I come to you with questions about game architecture (ie how unreal wants us to do things) as a complete unreal noob. We generally want to program in C++ but I suppose this question would be the same regardless of using bp or c++, and I'd like to prototype this in blueprint first. Consider this situation: we are making a game where the player needs to place cards on a square-grid board. These cards are like in tetris: they are the size of multiple tiles on the board, just like tetris blocks contains multiple squares. Once the card is placed, we no longer really care about what tiles belong to what cards; only the tiles really need to keep existing and we can effectively remove the concept of cards altogether. While placing, it would be nice to have them grouped such that the player can perform actions: movement, rotation, etc.

It seems to me the most logical thing would be to make each Tile a separate Actor. However, if we want them grouped, it would make more sense to make Card an Actor and each Tile in the Card a SceneComponent. I think, not sure. We will be generating the card shapes from scratch during runtime. What is the best way to group these actors together, in your opinion?

[winged zephyr]

Oops meant widget not canvas

[fiery ridge]

Where do you guys think it's best store stats such as character upgrades for singleplayer? So that they can be saved and accessed across different sessions/levels

[thin panther]

I would use the game instance, and then save them to a save game object

[fiery ridge]

Thank you

[dark drum]

You can use both. You can have a card BP that has static meshes to denote the tile type (driven by vars) and when placed, you can use this information to spawn the actual tile BP. Once all tiles are spawned you can destroy the card BP.

[dark drum]

The player state would probably be a better place. As you stated it's single player, it doesn't really matter but if there might even be a small chance you could add multiplayer in the future, go with the player state.

[worldly breach]

This does make sense, thanks!

[fiery ridge]

I plan for SP only, in that case, gameinstance better right?

[dark drum]

In singleplayer it doesn't really matter but if you want different saves/play through, player state might make it easier to manage. The game instance gets created as soon as the game is loaded which could cause problems if you try to do stuff before the world has loaded.

[fiery ridge]

Then gamestate can get loaded before anything happens yeah?

[proud wasp]

this is the first time seeing this type of issue , what is wrong with it?

[dark drum]

i cant remember the load order of the game state. I think it loads after the world has loaded. (I could be wrong though) The player state is loaded when a player controller is created.

[fiery ridge]

Thx

[median whale]

Hello, I'm currently a game tester interested in transitioning to game development. I'm a bit confused about whether to choose Blueprint or C++. I'm seeking advice on this matter from a seniors.

[thin panther]

both the answer is always both

[limber citrus]

editor

[thin panther]

don't really need aa senior to tell ya that tho

[dark drum]

What CuppaTea said but if you've not really done any programming before, blueprints will probably be easier to start with. Once you have a better understanding of the engine, you can start looking at things that you can convert to C++.

[frosty heron]

https://landelare.github.io/2023/01/07/cpp-speedrun.html

[dark drum]

That'll be why. The game mode doesn't exist until you start the level.

[limber citrus]

is there any work around, like something I can use without the need to start the game

I just want something global, so I can save some variables in, and read them inside other editor bps

[proud wasp]

anyone got an idea?

[limber citrus]

I gues game state and game instance will have the same problem

[echo storm]

Is there any way to set static mesh to "none"?

[dark drum]

Correct, they don't exist until you start the game. What sort of things are you wanting to save/store?

[limber citrus]

3x string arrays

[dark drum]

What for?

[dark drum]

Leave new mesh blank/none.

[limber citrus]

they contain level names, for each array there should be specific logic related to the editor tool logic

[echo storm]

I tried it like this but it doesn't work

It just keeps the mesh that was selected before

And there is no option for "none"

[frosty heron]

What are you trying to do?

[frosty heron]

with BP probably not possible. with CPP maybe you can use EditorSubsystem, I haven't use it my self. You can ask in #cpp

[lunar sleet]

Or #editor-scripting

[dark drum]

The one that shows 'Select Asset' isn't connected but is what you need. If you have already selected something in the drop down, you can click clear to remove it.

[distant hollow]

Hi all,
I used a "Async Load Asset" node to load a Static Mesh soft reference (using blueprints)
Past the "Complete" pin, I did a "IsValid" check on the output "Object", it returned True and even returned the name of the Static Mesh that was supposed to be loaded.
However, when I tried to set it to a Static Mesh component, it keep giving me a waiting message "Waiting for static mesh to be ready 0/1.".
Can someone tell me what is happening, and if there is any way I can check and confirm that the Static Mesh has indeed been fully loaded into memory before I use it, without having the disruptive "Waiting for static mesh" message appearing?

[frosty heron]

Show picture

[frosty heron]

Set the static mesh here on the completed pin

the picture that you showed doesn't reflect on what you write

[distant hollow]

I am capturing the essential parts in essence

[frosty heron]

Not really

i still don't see you setting the static mesh after it finished loading

you most likely got the error because it's not resolved yet

[distant hollow]

Essentially it is checking whether it has been previously loaded, before Async is called
If it has been previously loaded, it goes directly into casting, otherwise I add it to a reference list for counter-checking

In any case we can confirm that it reaches the Set Static Mesh node, because that's where the "Waiting for static mesh to be ready" box appears.

[frosty heron]

not entirely sure the order of what you are trying to do but here is a simple way to async load soft ref

I see that you have array as well

[distant hollow]

Yes, that is exactly what I did.

[frosty heron]

you have to becareful when doing Async stuff using a function

lets say you call the load function twice

if the first mesh is not loaded yet and second mesh get loaded then first mesh get loaded after

you won't get the latest mesh

[distant hollow]

There is no "latest mesh", I am trying out only with one mesh even.

[frosty heron]

try this then, see if you get any error

i mean disregard what you have right now and just do the simple version

[distant hollow]

That was where I started out with and it gave me that error, which was why I went further to do the checks and all.

[frosty heron]

There's a few stuff going on in your code that could possibly break things. You have delay and pins that go all the way back.
Try to load something with the 3 Nodes I showed above, see if you get any error

just have a test bp

and write that one function

[echo storm]

Silly me forgot to connect the node.. thank you

[frosty heron]

If u don't get error then it's the extra logic you applied when doing the load imo

[frosty heron]

Huh, why is it editor promt?

is that even related to the async load

[distant hollow]

Because I am running it in the editor ?

As in PIE

[frosty heron]

In Pie is fine

This is not PIE tho?

Not sure about that promt, I never had it but totally looked like the one that pop out when saving stuff in editor

[frosty heron]

which doesn't have anything to do with packaged version

[distant hollow]

Nothing to do with Packaged

On package it would simply get stuck

[frosty heron]

well that was never mentioned :

[distant hollow]

Which I don't want it to get stuck

[frosty heron]

I think you are still applying it in your function

it's most likely what break stuff

[distant hollow]

Which also should not get stuck since it is supposed to set to static mesh after Complete

[frosty heron]

you should just try to load it to Test

just with 3 nodes

nothing else

then you can probably deduct if it;'s your function that mess things up

[distant hollow]

No, as you can see, the function was skipped, it was done with that three nodes above

[frosty heron]

I'm still seeing many nodes which i don't know does what. My only suggestion is to do it in seperate BP and detach your self from what you have right now

because it work on my end with no problem whatsoever

[distant hollow]

Ok, thanks for trying anyway

I appreciate the gesture

[frosty heron]

gl, I am also doing the same thing right now

loading soft refs for my character customisation

[distant hollow]

If you can instead point me to a way to confirm that an output Object from the AsyncLoadAsset node has been fully loaded into memory, that would be very helpful

[frosty heron]

You can type the command to see what's loaded to memory

obj list class=staticmesh

For example

[distant hollow]

I'm using Blueprints

[frosty heron]

it's console command

you will see the result in your output log

[distant hollow]

I will need something that can return a value which I can use in the blueprints, not just reading in the logs

As in

I will not try to set the Static Mesh until I confirm that the Object has fully loaded into memory

[frosty heron]

it should be resolved (or loaded to memory) right after the completed pin

safe to load it

[distant hollow]

Well apparently it isn't

It should, but it isn't

Which is why I am trying to find a way around it now

[frosty heron]

you can check from the output log for debugging purposes

as mentioned

@distant hollow Try to write the command

you will see if your static mesh is actually loaded

try to restart your project first tho, incase if it's already got loaded. Because anything that the Editor loads will stay loaded till you restart the editor

[junior prairie]

So I've got this so far, does this look reasonable and how do I get a force in the direction the character is facing?

[frosty heron]

Try get forward vector

then normalised it I guess? not sure, I drop out from hs

[junior prairie]

yeah I tried this but it doesn't seem to be working

[frosty heron]

@junior prairie Try this

[fringe junco]

does anyone know how this node is used?

Im passing my grid data into but the pathfinding seems to use the navmesh and not this navigation grid thing

[junior prairie]

still nothing :/

[frosty heron]

no idea them, hopefully others can help. does hard coding even do anything?

if it doesn't then I would look at the add force node

[junior prairie]

I switched it out for Add Impulse and that seems to work, but even though I set the friction to 0 the player slows down so much

so now trying to figure out how to fix that

[twin path]

Does anyone have a tutorial on triggering events with a stream deck? Activating lights, niagara effects, animations?

[ruby cobalt]

something's fishy.. new project.. almost completely empty. I'm trying to add a widget to test things.. it won't show up.. so I dumb it down to "event begin play: print hello" and it won't even show?!?!

[supple dome]

did you place the actor on the map 😄

[ruby cobalt]

even begin play in level bp won't print

i must have done something weird somewhere idk

[lunar sleet]

Restart engine

[frosty heron]

If restarting don't work, check if you have print to screen ticked

[ruby cobalt]

ah it seems to be related to my game mode

and possible related to dlss

[lunar sleet]

That doesn’t make much sense but 🤷‍♂️

[ruby cobalt]

as soon as I removed my game mode.. hello showed up

[frosty heron]

could be just bugged, it wasn't showing up for me too yesterday

but it shows up in outputlog

can't remember what I did but i think restarting fixed it

[ruby cobalt]

LogGameState: Error: Mixing AGameState with AGameModeBase is not compatible. Change AGameModeBase subclass (BP_GameMode_C) to derive from AGameMode

[junior prairie]

that's a common mistake. If you're using GameModeBase, you need to use GameStateBase. if you're using GameMode, you need to use GameState

[ruby cobalt]

ah i must have changed that inadvertively

[lunar sleet]

Did you try to extend GS into a GM?

[ruby cobalt]

i don't use game state and player state much..

yeah changing it back to gamestatebase fixed it

[desert briar]

I want to reuse something, let's say a model + a light, as a component in multiple other blueprints. What are the options? ActorComponents don't render. ChildActors for some reason can't be edited in the editor. Do I really need to write code for this???

Goal is that I can edit the light in one single place and have it automatically updated in all the blueprints that use it

[lunar sleet]

Just place multiple instances of your light and on switch get all actors of that class

[desert briar]

I want to use it as component in blueprints. In some blueprints I'd like to adjust parameters of it

[lunar sleet]

Why does it absolutely need to be a component ?

[desert briar]

Because I generate a level with blueprint building blocks

I could add scene components to the blueprints, add tags, have code get them, bla etc

[lunar sleet]

What’s that got to do with not being able to use actors

[desert briar]

I'm looking for a way to not write code for this

One should mean the engine supports that use case

I could write code

but do I really need to

[lunar sleet]

Maybe I’m confused by what you’re aiming for. You just want to reuse an asset for a static mesh?

[desert briar]

i think questioning the use case doesnt make sense

could be anything

lets say you have a level part that has ... turrets

level partS that have turrets

you'd like to reuse the same turret everywhere, but would like to adjust the range or something for each level part

[lunar sleet]

Change variables

[desert briar]

so i'd expect to go in each level part blueprint, add a child turret component there, edit its properties

yes, but that's ass

[lunar sleet]

Use OOP

[desert briar]

that's also ass

is there an actual good way?

Not using it but I think even a garbage engine like Unity had nested prefabs

[faint pasture]

Hey we talking nested prefabs again?

[desert briar]

seems like it! let me search the channel

[thin panther]

Prefabricator is what you're looking for in this regard

Unreal's support for this kind of stuff is shockingly lacking

[desert briar]

Thank you!

[remote meteor]

huh

level instance/packed level instance is pretty much prefabs though

[true zealot]

I think this depends on how you want to do that....
I have a loupedeck so I'm not sure if stream decks specifically have an API or anything....
but I've done in this past by triggered json events that hit an HTTP listen server from built in loupedeck commands and then have also just done this with hotkeys.
You also might be able to use OSC to do it. I think your best bet is to figure out what/how you want to do this, and then zone in on a tutorial that targets that method from there

[dark drum]

Using your turret example, what I would do is setup the turret but use a data asset (or something similiar) that it gets its default variables from. That way you can create presets for the turrets. You can then place them where you want and just select the relevant data assets.

[dark drum]

In all honesty, I've never once felt the need for prefabs. Whilst I can't speak for everyone else, I can only assume the majority haven't either. With how old the engine is, if it was highly requested, it would have been added.

[twin path]

I would like to trigger a niagara fx 🙂

[faint pasture]

I'm doing modular vehicles and I do one part as one actor, and I just attached them at run time.

My game has a vehicle editor so if I want to pre-make vehicles, I just use that.

[true zealot]

so my guess is you'd want to make a command that sends a web request, or presses a hotkey, and then in unreal you'd want to listen for that request or hotkey combination and then activate the effects from a BP how you normally would once that event is received 😮
Sorry I don't know any more of the specifics

[orchid spoke]

im a bit confused about the animation blueprint here.. I added a notification in the animation to indicate when the character can start its attack. However, in the blueprint this notification is nowhere to be found. I've tried all 4 abps that come with my template, and searching for others in my content folder there doesn't seem to be one. (i also have a sword animations pack downloaded). I suppose it's recommended i make my own blueprint? It's just weird the blueprint doesn't exist with already fully functioning animations. Or is there some other issue here? Thanks
Maybe the issue is my sword animations use a different skeleton than the one used in the animation blueprint? But i can't seem to edit what skeleton is used in the preview.

[desert briar]

No, clunky for my use case. I spawn the turrets alongside my level parts, so it's convenient if they're part of the level blueprint. I can use child actor components for that. I'm tweaking the turrets a lot, pretty much for each level part. But for tweaking variables per turret I now have to use blueprint in each level part (because child actor components don't expose properties), and also can't debug the child actor turrets in the editor

I could also set some variables in the level part blueprint, spawn turrets as actual actors on runtime, bla. Everything is possible, it's just inconvenient. I'm I was looking for a workflow-friendly solution

[radiant imp]

What could be the reason for world location to be 0,0,0 even thou i have a valid player controller?

Or what causes the return value to be 0?

[dark drum]

What are you using the level blueprint for?

[dark drum]

are you doing local multiplayer?

[desert briar]

Sorry, I managed to make progress here with the answer of @thin panther (thanks a lot), there's no value in discussing my use case further, need to work on my game

[grizzled sparrow]

there's a way to make the arm of the default dummy follow the mouse while pointing at it?

[dark drum]

What type of notifier? A skeleton notifier or custom anim notifier?

[radiant imp]

Yes exactly

[remote meteor]

tfw we have Actor Pallete and Level Instancing and we are still lacking

[orchid spoke]

custom

[dark drum]

how have you set up the custom notifier?

[radiant imp]

It's super weird, i do have mouse events on the same player controller at the same time. The player controller is valid and after switching players it works fine

[dark drum]

Well from my understanding (I could be wrong) there's only ever one cursor which I would imagine the first player would get so anything other than index 0 would probably return 0,0,0.

[orchid spoke]

just picked the moment the swinging stops in the animation i added a notif called canattack

[ruby cobalt]

as "cast to skeletalmeshactor" expensive? like should I avoid running it at event tick?

i could easily cast as skeletal mesh before event tick and use a branch somewhere to run the static mesh version or the skeletal mesh version of my thing

[dark drum]

That looks like a skeleton notify event meaning it'll only show on the animBP setup to use that skeleton.

[dark drum]

What are you trying to do?

[orchid spoke]

ah so it is as i thought.. Is there some way to easily find what bp is used for this skeleton?

[remote meteor]

https://intaxwashere.github.io/blueprint-performance/#3-do-not-use-cast-its-expensive

[dark drum]

It looks like the old UE4 manny. I don't think it has one setup be default. Im pretty sure it's only in there to help people retarget from the UE4 to the newer manny and quinn manquins.

[ruby cobalt]

attaching objects together using physics.. but if the parent is a skeletal mesh, I care about the bone and its position.. if static.. no bone..

[radiant imp]

Ok, thats very likely the problem then. I'm doing shared keyboard and shared screen and messing with CustomViewport. Annyoing to debug 😭

[orchid spoke]

ah so i just need to 'retarget' and it'll fix everything then? I'll figure out how myself as long as it fixes it : )

[dark drum]

I believe retargeting will create a copy for the new skeleton, you would need to add the notify for the new animation but should then show in the animBP. (assuming it's using the manny/quinn skeleton.

[dark drum]

Personally, I would avoid casting on tick as its an extra check. I would need to see more of what your doing to suggest an alternative.

[orchid spoke]

great thanks for the help 😃

[dark drum]

no probs, i only learnt about skeleton notifiers the other day haha.

[ruby cobalt]

makes sense.. I have the same "situation" for 2 functions so I feel like this might be quite generalized..

I want to be able to set either a static mesh or a skeletal mesh as a target or parent.. but I only care about the bone if it's a skeletal mesh.
Suppose I need the location of my target.. if it's skeletal, I want to use a specific bone.. if it's static.. I can't use a bone.
That's the system I'm trying to build.. make it compatible with eithe rstatic or skeletal

[dark drum]

I need to know more about what your actually doing on tick.

[ruby cobalt]

okay in one of those function.. I want to focus my camera on either target 1 or target 2.. either target can be either static or a skeletal (for which I specify a bone)

I then have a crossfader to let me change my focus from target 1 to target 2. so On tick, I get the location of both targets.. and pick the value that would be either on one of them or somewher ein between

let me clean up the BP and screenshot

[dark drum]

You can just use the 'DoesSocketExist' node. It takes in a scene component so will accept both static meshes and skeleton meshes.

[ruby cobalt]

oh that's a good idea

thanks

i have another kind of dumber question. here,s the system that only cares about a static mesh (no bone nothing)

Is it worth it here to use the branches? or should I just use the lerp way at the end?

(this thing runs at event tick)

[radiant imp]

Heey, thx for the help. The problem was actually that that the first local player wasn't the one being shown on screen. Shared screen with several local PlayerControllers is a nightmare in unreal 😬 😅

It's working perfectly now 👍

[dark drum]

that looks fine with the branches. I usually do a similiar thing.

[ruby cobalt]

great

and now to make it care about possible bones.. I'd add this in there instead of the basic "get actor location"

[dark drum]

This might help you, this is how I get my player characters head to look in the direction of stuff. Doing the calc to just get the location can be better as the updating stuff would then be the same regardless of if its a skeletal mesh or not.

[radiant imp]

why do your blueprints look so straight?

[ruby cobalt]

thx.. do you run this with event tick to animate the head as things move around?

[ruby cobalt]

flat node plugin (free on marketplace ) for the flat nodes..
electronic nodes plugin (paid on marketplace) for the straight lines

[radiant imp]

cool

[dark drum]

Yea, and the animBP gets the value to update the relevant bones.

[ruby cobalt]

maybe i care too much about optimisation

[remote meteor]

i dont think you need the top 2 branches?

[ruby cobalt]

yeah I see.. but considering the new code replacing "get actor location" would be heavier.. it makes sense to not get the location of actor 2 unless i need it no?

[remote meteor]

at the cost of checking 1~2 floats equal to something and a branch though

[dark drum]

O yea, he's using Lerp, i thought it was interp lol. @ruby cobalt Yea, if your using lerp, you won't need the two branches.

[remote meteor]

anyway, indeed its overthinking about optimization at this point

[ruby cobalt]

yeah probably

[remote meteor]

if we are that focused on every tiny bit, might as well do it in cpp

[ruby cobalt]

but I think it's worth it to learn things the proper way on the long run

I've been able to do weird stuff with tech without being a programmer because I care about optimization.

[lunar sleet]

It’s a fine line

[remote meteor]

if i remember correctly

[lunar sleet]

Premature optimization is just as bad tbh

[remote meteor]

comparisons are kinda slow compared to straight forward operations

cus of cpu branch prediction yada yada, idk how true is that these days

if branch predictino misses then pre-fetched cache is wasted kinda stuff

[ruby cobalt]

during play, I won't change those actors.. so in theory, if I check at begin play and use a simpler branch at event tick.. things would be lighter?

I know in practice it migh tnot make a difference

[remote meteor]

i would suggest not to take away flexibility too much though

if the code only runs this part, it works perfectly fine

the only question i would ask is whether if it needed to be on tick

[ruby cobalt]

good advice

well.. actors can and will move

and I need the focus point to stick to them

[remote meteor]

if actor A and B are constantly moving target

then now the question is what is the use of focus point?

camera focus point?

[ruby cobalt]

yes i want my camera focus to follow a bone.. but then be able to crossfade that point of focus over to a 2nd bone or actor

i use very short depth of field too.. so it makes a big difference

[remote meteor]

is the camera component on the focus point or a separate actor?

[ruby cobalt]

they are seperate.. this code runs within my custom cine camera bp.. the focus actor that I move around is a basic sphere thing that I usually hide

[remote meteor]

because when it comes to game engine level, the stuff about branch prediction yada yada i mentioned is probably ignorable

needing to update the transform and the scene of focus point actor is probably 10x heavier than some variable checks

because if its just the location that you need to know, it doesnt need to be a whole actor

the camera can figure out where it should point at by knowing the location of the 2 actors and the crossfade variable

the camera on tick, would still do the lerp between their location, and project from location to where it should be, to be able to look at the point

[ruby cobalt]

here the first screenshot checks at begin play

and this would run at event tick

[ruby cobalt]

yeah no doubt..

[ruby cobalt]

oh yes of course! I will do this.. and then I can just move the focus dot there only if I need to see it to troublehshoot.. that's good advice..

[remote meteor]

if both actor are supposed to have a "watch point" for the camera

i would make an interface for the actors to return a location, GetCameraWatchLocation() or something

[ruby cobalt]

ah wait.. that's why I've been doing it this way..

So I'd need to change it to manual I believe?

[remote meteor]

the actor itself will know whether it is a static mesh or a skeletal mesh

the camera doesnt need to check every tick whether if you are static or skeletal

[ruby cobalt]

so you'd set that "watch point" in the actor itself?

[remote meteor]

the actor will return the correct watch point that it should have

[remote meteor]

ah, auto focus, havent been using that much, but im guessing there is an option for location or distance/focal length

[ruby cobalt]

a believe manual works with a distance from the camera..

[remote meteor]

that works

[ruby cobalt]

true

[remote meteor]

you can figure out the distance between the camera and the watch point

[cosmic storm]

Someone could help me understand this program in detail, especially the get player controller and the Subsystem :

[ruby cobalt]

and even offset it.. and then move a visual debug focus dot there if I need later

[remote meteor]

yeah but then 😅 all these work probably doesnt really improve performance that much though

one less scene update

thats about it

[ruby cobalt]

yeah I see

but on the long run.. if I learn good tricks now.. this will carry over to thousands of little things

[remote meteor]

yeah good to have arsernals of tools

i would probably take it as exploring the possibility

[ruby cobalt]

yeah

it's a matter of having the time to invest

[remote meteor]

though in production, it doesnt make anysense to do such premature optimization

having unlimited time is always the best

🥲

[faint pasture]

the Mapping Context is the mapping from actual inputs (buttons etc) to input actions.
This code is adding a context for player 0 on begin play

[ruby cobalt]

yeah I'm actually somewhat short on time

[thin panther]

It doesn't make much sense in bp. Your biggest performance game would be writing this in C++.
Make the thing and then profile it to see if it needs to be optimized

[faint pasture]

Yeah you'll see about a 100x speedup going from BP to C++. If it's that important, do it

Trying to go branchless and playing nice with the predictor in BP is a fool's errand. Although it still makes sense to keep certain performance considerations in mind like not putting unnecessary stuff on tick etc.

[thin panther]

Yeah, a good sensible practice from the getgo is very importantly not a premature optimization, but things like this is, when you have much lower hanging fruit

[terse trout]

hey folks, i'm creating a dynamic material instance here and using it to set parameters right away. but the MI Level Badge is not valid after being created. any idea why this would happen?

[lunar sleet]

Did you use breakpoints to see the code flow?

Does it just always go to invalid? Where is it being run? Is it possible you’re unsetting it somewhere else

[terse trout]

i've been following my logs every step of the way (i have to test this in build, the functionality doesn't work in editor). i create the dynamic material instance on widget preconstruct and i check it later here in the function i posted above. it always goes to invalid, attempts to create a dynamic mat again, and when i use it to set a parameter -- it's still invalid

[lunar sleet]

Why doesn’t it work in editor?

Idk about creating it preconstruct, you can’t save an instance before runtime

[terse trout]

because i need to connect to the server to pull info, etc. long story. i'm trying to fudge it to work in editor rn

[lunar sleet]

#umg knows more about this stuff but afaik widget preconstruct is like construct for normal bps. Can’t really create instances at that stage from what I’ve seen so I doubt it’ll ever return valid for you

[terse trout]

ok so can confirm, it works in editor but not in build. i stepped through with breakpoints and the dynamic mat instance gets created with no issues in editor. i'll ask in umg too. thank you!

[wet sonnet]

heyo, new to Unreal here. I'm trying to make a widget that has 4 custom slider inputs on it. When one changes value, the other 3 adjust their values so that they always total 1, or 100%.

to do this, I'm listening to their onvaluechanged events from the parent blueprint, and invoking a NormalizeSliders function, passing in the index of the slider to adjust the others relative to.

However i'm having trouble understanding the limitations of Events and Event dispatchers.. I would like to say "When slider 0 emits its onvaluechanged, call NormalizeSliders(0). When slider 1 emits its onvaluechanged, call NormalizeSliders(1). When slider 2 emits its onvaluechanged, call NormalizeSliders(2), etc." But i can't seem to find a way to execute arbitrary code (i.e. invoke NormalizeSliders with some value) in response to an event emitted by the slider objects. All i can do is bind events to events, and their signatures *must* match, so there's no opportunity to insert that contextual slider index.

here's the rough shape of what I want. (but without needing a separate customevent for every child slider)

[pulsar pulsar]

whats the best way to save inventory related stuff? I'm trying to stay away from tutorials as it's just do this do that and I feel i'd learn more by´trying to figure it out

[frosty heron]

You should look at how others implement such system if you have no experience at all

[pulsar pulsar]

so

[finite maple]

the tile/platform itself has no blueprint of its own, i just refrenced it in the button blueprint with an object reference variable

[pulsar pulsar]

tutorials lol?

[frosty heron]

Or marketplace stuff like dynamic combat system, that's where I learn to do stuff with inventory

I can't recommend any tutorials from YouTube for actual system

[frosty heron]

Hmm then relative to what?

If you target a component with no parent then it has no relative transform imo

[dark drum]

You can bind an event to a function. If you use the 'create event' node, you can create a function (or event) that matches the dispatcher signature.

[dark drum]

That would depend on how you're doing your inventory and what type it is.

[finite maple]

what can i do then

[frosty heron]

Show me the detail panels of the platform

[pulsar pulsar]

is it free? I can't afford anything atm so I'm kinda limited.

[frosty heron]

Want to see the hierachy

[frosty heron]

Nah it's not free

[frosty heron]

But you said earlier the platform has no bp?

@finite maple

[wet sonnet]

that's the thing. the dispatcher (which is the event the child sliders emit) doesn't know its index within the list of sliders, so it cannot include the index in its signature. therefore a matching signature would be lacking a variable i need (the index). ALSO, making a separate function or event for each slider seems... unideal? like shouldn't i just be able to get a control pin out of the "OnValueChanged" itself and use that to do whatever I want? let me know if i am not making sense haha

[frosty heron]

You can have payloads when calling dispatcher

[finite maple]

yeah? i mispoke then

srry

[frosty heron]

@finite maple so which one is the platform? The box or the static mesh

[finite maple]

the static mesh

the box is a collision box

[dark drum]

You could create a widget that just has the slider in it that binds an event to the on value changed which calls a custom event dispatcher with an addition input. You can then have it pass it's assigned index you give it when your create the widget. You then use this widget in your main widget for the slide and bind to the custom dispatcher.

[frosty heron]

One way to do it is to cast the object ref to your bpfloor tile, get the static mesh from there and set the static mesh relative location

@finite maple

If you don't want to cast then there is get component by class route

Tldr you want to update the relative location of the static mesh

[finite maple]

how do i get the static mesh from my cast?

[wet sonnet]

that sounds like more of a mess instead of less, but it would at least make the parent code a little cleaner.

i mean at the end of the day, this does look like it works:

[frosty heron]

You need to cast to bp floor tile

[wet sonnet]

it's just such a mess. like there's no way this is the right way to do this. no way this is canonical blueprints

[frosty heron]

Then from the blue pin you can drag and get static mesh

[finite maple]

ohh i see

[frosty heron]

Looks shocking

If you need the custom progress bar to have index, you should just have a variable called index inside the custom progress bar and make it instance editable

Then in your main widget, select each progress bar and assign the index accordingly

You can also make dispatcher that return it's reference, index and value. And call it on slider on value changed

[dark drum]

Probably just how I explained it but in essence, my method is just making a wrapper widget for the slider so you have a new slider widget that gives you more information for the on value changed.

Also the method you have will issues depending on modified slider index. The normalize sliders would just use what ever the value is when it's called.

[wet sonnet]

oh right i forgot to mention that - is there a way to just drop a constant into the blueprint graph? i only seem to be able to make variables that have scope beyond the control flow i use them in

[dark drum]

There's local vars in functions and literal values for some variable types.

[frosty heron]

@finite maple your platformtoactivate variable

[finite maple]

https://tenor.com/view/giygas-cat-melon-cat-psychotic-gif-25770926

[frosty heron]

You still haven't change the target to static mesh

[wet sonnet]

also yeah, the sliders actually already are custom wrapper widgets that contain functionality - i just wasn't satisfied with the "give them their index onconstruct and emit the index with the value changed dispatcher" solution, because it's a similar amount of mess but more compartmentalized, as well as because it's coupling the custom slider widget with this one specific use case which shouldn't be necessary, as well as because it's distributing concerns across multiple classes instead of the one class that actually cares about this behaviour.

if I could just say "when slider 0 emits this event, do this", this whole thing would be significantly easier to code and to understand. So i was hoping there was a better way. And i still yearn to this day

[frosty heron]

From the blue pin drag and type get static mesh. Then from that static mesh you got, drag the blueprint and type set relative location

[pulsar pulsar]

ah okok

[finite maple]

that worked 😭 😭

thank you

[frosty heron]

No worries but your code will only work with bp floor tile since you cast

If you want to make it more ambiguous, you can use get component by class

[finite maple]

is that only a problem if i want to make a button activate multiple platforms?

because it's not my intention

but i'll keep it in mind anyways

[frosty heron]

You should contain the logic for the activation in the bp floor tile if that's the case

Then from your gameplay manager bp you can just activate any platform you like

[frigid swallow]

how do I change a character's animation based on what they're holding? For example, when holding a sword, it plays a different running animation.

[frosty heron]

Blend posses by enum

You can create enum that hold the state of your character.

Eg short sword, long sword, spear, etc

In your anim instance, you can have various blend spaces that will get played according to the enum

https://docs.unrealengine.com/4.27/en-US/AnimatingObjects/SkeletalMeshAnimation/NodeReference/Blend/

Jump to blend posses by enum

[lunar sleet]

I’d no idea that existed

I haven’t really touched animation tho 😅

[frosty heron]

Just another thing I picked up from dynamic combat system 🐋

[lunar sleet]

How much did that cost ?

[tight pollen]

what do you think about storing widget references in Data Asset? I know that's not how it's done, but if at the beginning of the game I cleared the arrays of references and loaded them from SaveGameObject and put them back into the DataAsset?

then I can easily access a given widget from any widget, I don't have to do Cast To or create a variable with a reference

[stone field]

It seems like an interesting idea, for some commonly needed widgets. Maintaining a full list of everything in the game might be cumbersome though

[tight pollen]

I would use Map variable

each widget would have its own unique ID

DataAsset is only for Client side?

[lunar sleet]

A good question for #multiplayer

Widgets are client side tho afaik

[ruby cobalt]

Here is a workflow question.

I need to cover a few cases using parent and child classes)

BP_driver (lets me move the actor manually in smart ways using pivot)
BP_physicsControl (let me use physics control so attach and move the actor)

Some actors would need both classes, and physics should be the child of driver.
Some actors only need physicsControl as their parent..

How do I organize this to be able to pick one or the other or both?

I think I could change it so PhysicsControl wouldn't need to be the child of driver.. but I don't think physicsCOntrol should be the parent of everything

[lunar sleet]

Can you implement this stuff in actor components instead?

[ruby cobalt]

maybe I don't know what that means

they kind of are interdependent (physics control's child that I attach to various actors, is the pivot I'm using in BP_driver)

I have a video example where I built both physics and driver in the same parent class to attach a camera to a skeletal mesh.. maybe that would make more sense

I'm looking for ways to make this more modular because I feel like driver and physics both in the same class is a lot of stuff and not modular enough

https://www.youtube.com/shorts/h6aZphAkW3g

Here the camera is a child in orbit around a pivot (using bp_driver stuff)
The pivot is then attached to the hand using Physics.

[lunar sleet]

That’s what actor components are for. Modularity

They’re pieces of logic you can attach to actors dynamically

[ruby cobalt]

i'm watching the wadstein video on the subject.. hopefully I can figure out how to adapt to it

ahh I see.. damn this is a lot of work to plan all of that out

[surreal juniper]

I have some collision boxes set up for ledge grabbing purposes. The ones circled in green work, collide with the line trace and all that. The rest just don't. The two that work were also the first two I set down and every subsequent one I set up doesn't work (copy+paste, drag from content drawer, doesn't matter) and they are all the exact same actor. Do I have too many? what do I do to fix this?

[lunar sleet]

Welcome to game dev 😀

[snow skiff]

Hey! Is there a way to SetRelativeLocation only for one axis?

[lunar sleet]

Depends, check the collision settings on all of them

Break the input pin

[surreal juniper]

They all share the same collision settings because they're all the same actor?

[lunar sleet]

Feed the existing vectors into the other 2^

[snow skiff]

Okay so if i leave them unconneted they just refer to the number on the node?

[lunar sleet]

They’ll default to 0

If you want current, get relative location, break output, plug the ones you don’t want to change

[lunar sleet]

Draw debug your line traces

[snow skiff]

Okay i get it now it works thank you

[surreal juniper]

Yes I have, and they are not colliding at all

[lunar sleet]

Show

[lunar sleet]

🤔 Maybe your trace is too short ?

You can also use show collision console command

[surreal juniper]

I don't think it's an issue with the trace. The boxes are all aligned exactly the same with the geometry, and it works fine for the two green circled boxes

this is the working one

[lunar sleet]

Maybe, but your trace looks perpendicular to the ground so I’m confused as to where your trace start and end are

[surreal juniper]

starts slightly in front of the model and ends same distance from model but down on the z axis

[lunar sleet]

Why

[surreal juniper]

to catch a box in front

[lunar sleet]

I thought the boxes are above?

[surreal juniper]

as they're falling

so the boxes would not necessarily be above

I can change it if I need to but it's not really an issue

just a number change

[lunar sleet]

Maybe you should use an overlap instead

[lunar sleet]

It’s obviously an issue if it doesn’t work lol

[surreal juniper]

But it does work

Do you think the issue is with the line trace?

Why would it be working with some but not other collisions

I'm not saying you're wrong, I just want to understand

[lunar sleet]

Simple test, print your hit actor, if it’s anything other than your collision box and you’re 100% sure the collision settings on each box are the same, then yeah prly

[faint pasture]

How do you detect a ledge? This looks lie you trace out, then down?

Explain your algorithm for finding the edge of something

[surreal juniper]

one moment

[surreal juniper]

I did this. When I collide with the boxes that work, it prints a message. It doesn't do this with the ones that don't work

[lunar sleet]

So it’s not hitting

Which we’ve established

[surreal juniper]

Yes

[lunar sleet]

I’d try a collision box in front of your char and use onComponentBeginOverlap

[surreal juniper]

I created a new trace channel which is exclusive to these boxes for the purpose of ledge grabbing. There's a line trace that draws out and if it hits one of these boxes it puts the player into a ledge grab state (no gravity, etc)

[lunar sleet]

But maybe a diff trace algorithm would work too

[surreal juniper]

I can substitute the line traces for box traces

[lunar sleet]

Maybe that too

If you do switch to overlap, rmbr to adjust settings from block to ovelrap

But if you want precision to make sure it’s facing the right way, then yeah better to keep trace

[surreal juniper]

I think the issue with box collision is it could hit multiple boxes

[lunar sleet]

Also pls show line trace code just for sanity check

[lunar sleet]

What’s connected to hit hit actor

[surreal juniper]

that's the print

But I'm sorry! The line trace wasn't colliding with any of the boxes at all

Apologies

[oak fable]

hey there i need some help with setting up my animations
im making a combo system and its working fine but i get a glitch in the anim montages
which is i have anim notify for resetting the state of my attacks and others for saving them so now if i play one anim montage but something interrupts it like doing left hand attack or maybe change the to other movement state it wont reset so how can i check if im in attack state but no animations playing for like 5s and then it should reset the state

[surreal juniper]

I'm sorry 😭 I will try to troubleshoot

Thank you for help although it was an impossible task

[lunar sleet]

Did you make sure that your boxes are set to Block the LedgeGrab channel?

[lunar sleet]

Np, collision likes to mess with you that way 🙂

[lunar sleet]

Have you tried #animation ?

[oak fable]

i mean like any way to check if there is no mouse input for 5sec and the state is set to attack then i can reset it

[oak fable]

its more to coding then animations

[oak fable]

but yeah i posted there just incase

[lunar sleet]

I saw anim notify that’s why I asked, those are a bit diff but it looks like it’s something else

[oak fable]

im kinda not good at explaning what i need XD

[lunar sleet]

If I understand this correctly, you want to not be able to do something while an animation is playing?

[oak fable]

yeah

or at least until one of the notify hits

[lunar sleet]

How about settting an isAnimating bool to True and back to False when the notify hits. And only allow the new one to go through if that bool is false

This way you don’t have to worry about precise time which involves dealing with frame dependency etc

[oak fable]

how excatly i can set that up

it should be false in the anim notify or the function inside it ?

and when to set it to true

[lunar sleet]

You can have it False by default, set it to True when you begin animating, back to false when your animation end notify hits

[oak fable]

okay but where do i call it ?

[lunar sleet]

Call what, the branch?

[oak fable]

the isAnimating bool

[lunar sleet]

You can’t call a bool, if you mean the branch that checks if it’s False, you put that right before attempting to do the other attack or w/e it is

And even before the same action so you can’t interrupt it by pressing the same button

[oak fable]

like in attack input key before i call the perform melee light attack ?

[oak fable]

or inside it

[lunar sleet]

Input -> check if animating -> if False -> perform action

[oak fable]

it will be true when i start the animation and when it end i should set it back to false

looks like i got the idea thanks ❤️

[lunar sleet]

You can do it either way, and can use a NOT bool if needed

[oak fable]

sure thanks

[lunar sleet]

Wait, didn’t we go over this yesterday ?

[wet sonnet]

I have a group of sliders in a widget. When one slider's value is changed by the user, i am modifying the values of the other sliders. This causes an infinite loop of OnSliderValueChanged events. Is there a way to set a slider value without triggering that event, or to distinguish between the two sources of the event?

[lunar sleet]

Yeah we did, I rmbr you pointing at the wrong node when we told you it’s Set Health that’s the issue

Might have been two days ago but it looks like you just skipped our replies

[lunar sleet]

Show code

[wet sonnet]

1. user mouse-drags a slider, which is part of a custom widget wrapper.

2. the onvaluechanged event of the slider triggers an event dispatcher from the child widget.

3. that eventdispatcher is observed by the parent widget, and invokes a function that adjusts the other sliders in response to the user's input.

4. at the end of a bunch of irrelevant math, the adjustment function calls [CustomSliderWidget].SetValue, which in turn calls Slider.SetValue inside the child widget.

(4) is triggering (1), causing an infinite loop.

lol i hit enter early

1 sec

okay there

i EITHER need a way to check if (1) was triggered by the user or by my code

OR a way to set a slider value without triggering its OnValueChanged

[faint pasture]

If there isn't then make your own UpdateSliders event

[wet sonnet]

could you be more specific? there's a few parts here i might call an "UpdateSliders event"

[faint pasture]

Act as if there's no such thing as OnValueChanged and make your own function

then you can only manually call it when you want to

Or try this

[wet sonnet]

if I want it to trigger when the user changes the slider, i have to use Slider.OnValueChanged, right?

[faint pasture]

set some bool in SliderValueChanged, some bool that would be gettable from everywhere that cares about it

[wet sonnet]

so it doesn't matter if i wrap it in another layer of abstraction

[faint pasture]

Branch on the bool, set it false, do your math, set it true

do that branch in all bindings. A trigger of the OnValueChanged should be blocked until the end of the initial update logic.

that should block your on value changed stuff from running until the end of the update/modification code

[wet sonnet]

okay, that works. Is there really no way to set a slider value without triggering the event?

feeling like unreal BP is 95% working around weird limitations like this but i can endure

thanks though!

[oak fable]

i tried but dont know why its not working

it only play the animation once

[lunar sleet]

Use breakpoints to make sure it’s getting set back to false

[oak fable]

yeah it should be

i dont why but when i set it to false it works

[upper jackal]

Quick question, have any of yall had the issue with input actions dissapearring after you reopen the project in the editor? I've saved the blueprint and the project several times and it doesn't save it

[surreal juniper]

I had a player blueprint that was working fine until I changed absolutely nothing. Now, I'm pretty sure it's saying it doesn't exist. When I start the game, the model is missing, I can't move anything except the camera, and when I quit the game it shows me a billion error messages.

Really frustrating because I didn't change anything. I've restarted the editor a couple times

[lofty rapids]

the one where you set it to false is the notify event that you set ?

[oak fable]

i set it to false using the notify

[lofty rapids]

AN_ResetState ?

[oak fable]

yeah

also tried to make one for it

but not working

[lofty rapids]

did you check to see if the event was even firing ?

that you had the right node

[oak fable]

yeah it fires but still dont know why its not working

[lofty rapids]

is the cast failing ?

[oak fable]

idk

[lofty rapids]

drag out from the cast failed and do a print string

[oak fable]

but seems like it

[lofty rapids]

see if that shows up

[oak fable]

okay one sec

[lofty rapids]

i would of started with a print string out of the event too

just to be sure

[shy canyon]

how can I rotate something but use a custom reference as my pivot?

[fringe junco]

does anyone know much about how these Add Local Navigation Grid for Points nodes work?

i can set them up but they dont seem to do much lol

[oak fable]

the cast in the anim notify not showing while playing

[lofty rapids]

so it's not showing failed

[oak fable]

nah

[lofty rapids]

you put a print string comming right out of the event ?

[oak fable]

yeb

[lofty rapids]

what is reset state ?

[oak fable]

what i found is i need to have it more away from the save attack anim notify and i would need to click real fast to be able to do the next attack

[thin panther]

Do me a favour and open the character blueprint and click the character movement component. Confirm for me if it is completely blank and shows nothing

[surreal juniper]

In the details panel? it is blank

[surreal juniper]

^

[thin panther]

thought so

You've run into the super fun and not at all annoying engine bug of 5.3 known as "why did my character just delete itself"

[surreal juniper]

guh

yes the skeleton mesh is also gone

[thin panther]

so you have a couple of options here.
1 - roll back in source control (if you aren't using it, set it up now)
2 - check to see if you have any previous autosaves
3 - remake the character

[surreal juniper]

What is source control?

I did check for previous autosaves. No such luck

[thin panther]

basically version control on steroids

you keep submitting your changes, and at any point you can roll back to a previous change

you can also branch off into multiple avenues of the project and seamlessly switch between them,
source control has a lot more use for code, but for any project its a nice just-in-case

oh if you set up the engine integration you can also "diff" blueprints, which is seeing the difference between your file, and the same file at any other point in time

#ue5-general has a great guide on setting it up in the pins. Ignore the bit about GitHub though, that's not a good host, you want to use the bits that mention Azure DevOps

[surreal juniper]

Okay thank you

I'm going to have to remake the character

Is this a common bug?

[thin panther]

i wouldn't say it's common, but I ahve dealt with 3 other users with the exact same issue, who also did nothing to trigger it

not that anything you could trigger should do this

you can't just delete all the properties of a c++ component

so rare, but frustratingly so

[surreal juniper]

I hope the next update comes soon

This bug was devastating to my morale!!

[lunar musk]

Any idea why vfx look like this?

[hardy fable]

looks like the material is either not compiled, or broken

[noble ledge]

Inventory Widget Ref is a UUserWidget. How is it able to call a interface function?

[dawn gazelle]

If the actual widget stored in the Inventory Widget Ref implements the interface, then it would attempt to access the interface on the widget that is stored in that variable.

[noble ledge]

hmm ok

[dawn gazelle]

What that node does is basically check if the reference passed in implements the interface, and if so, would return the array as defined in the reference's implementation of that interface.

[noble ledge]

Yeah I was just confused because its a default UE type and its calling a interface function and I couldn't see any connection.

[dawn gazelle]

Yeah that's the beauty of interfaces. It's a means of predefining functions and letting other classes handle their implementation of those functions, so even if you use a generic reference, like AActor or UUserWidget, if the actual class of the reference implements the interface, it will properly execute it as it was defined to do.

[noble ledge]

What if it was a widget that did not implement that function?

[dawn gazelle]

Then it would still attempt to execute it, but in this case, the array would return empty.

You can use a "Implements Interface" check before attempting to access if you want to make sure you know your reference does utilize the interface.

[noble ledge]

Oh ok cool. Thanks for the help

[dense badger]

I'm having an issue with my character camera / spring arm. I have a pretty standard 3rd person camera setup with a camera on a spring arm with some camera lag. It's also set to affect the players control rotation. The issue is when I teleport the player I can't seem to find a way to reset its rotation to match that of the player. All attempts to manipulate the camera post teleport seem to fail.

[tough atlas]

I just started building an object grabbing system, but am stumped trying to getting the PhysicsHandle to release the target if it gets to far away from the player, any iteas?

[hardy mango]

for whatever reason i'm not marrying this logic here.... i'm trying to setup a spline (ultimately splinemesh) to draw from this TargetActor (has a hit detection to ground - END POS) back to the character (Yellow DebugSphere). I cant get the position to go to the character for the life of me.... What am I missing?

[frank sundial]

Hey so I made a sprint feature ealier today ( I was tryin make a slide) and i was wondering if I could copy most of it, add some nodes and get a slidign feature out of it. Would anybody know what i would need to add?

[rapid helm]

hey y'all i'm havin a lil trouble with this, which node do i connect this with?

[hardy mango]

whatever your AreaWithEnemies is...

[rapid helm]

It's a collision blueprint

[hardy mango]

Do you not have an object reference?

I"ll assume by picture its the CubeCollision ?

[rapid helm]

It is Ya

[hardy mango]

why are you casting to it then?

Where is this code located? In the bluepring WITH the cubecollision?

[rapid helm]

This code is in the third person blueprint

[hardy mango]

do you have an object (or expect to have one) in the world of type AreaWithEnemies ?

[rapid helm]

there should be albeit that's the problem because I have no idea how to get the reference

I don't understand lots rn

[hardy mango]

GetActorsOfClass(AreaWithEnemies)

Will return an array. Iterate that array (ForLoop) AND MAKE SURE you do a validated get first - otherwise you're prone to crashes

that is of course - if you cannot get a direct reference to the exact one you're wanting to obtain.

[rapid helm]

I'll try it out

Thanks brother

[frosty heron]

Like 50 bucks 🫠can't say it's a really good one but it was very valuable to me as It can be picked up and used by people whom are learning.

There are things like input buffer, inventory system, skills, buffs, combat system including block and parry.

[lunar sleet]

Nice

[oak fable]

im trying to make a dodge based on the direction so all the other directions works find but the backward doesn't
is the values right ? or im mistaken

[spark steppe]

is it possible that some of the other conditions also fulfill the condition for backwards?

[oak fable]

i believe no the direction when i click on the backward key is 173 or something close to that

[spark steppe]

it would be more readable if you used in range at least for the ones which don't flip over

yeah, but does it play no montage at all or another one?

[oak fable]

no montage at all

that means the calcs of the direction isn't right

[spark steppe]

the animation is assigned to the variable?

[oak fable]

yeb

[spark steppe]

then i have no idea

[oak fable]

what is the angle for the backward

or backleft to backright

[spark steppe]

that depends on where you take the sample, e.g. if the character can face any direction in a 3D world and you take the character rotation, then backwards will always be another value

eventually you want something like the dot product of forward vector and 0,0,0 and work with that (nvm that wont give you the left/right direction)

[oak fable]

it face one direction

so the forward always 0

back always 180

[spark steppe]

well then the range is correct for your backwards dash

[oak fable]

then why its not playing
when i debug it
it stops right on the branch

[spark steppe]

with which value for Dodge Direction?

[oak fable]

thats mean the direction i have which was 173 isn't true
for the branch

[oak fable]

the branch is
direction >= 135 and direction <= -135

[spark steppe]

oh

you have a condition which can never be true actually

[oak fable]

why

[spark steppe]

it can't be >135 AND <-135

[oak fable]

oh i see

i used the or before but that didnt work for the left and right

[spark steppe]

screw it, too late for math 😄

[oak fable]

that worked

[oak fable]

i hate math

but i have to learn

[spark steppe]

but that's also true for all other dashs

[oak fable]

how

[spark steppe]

nvm

[ancient basalt]

i have i problem in passing an vector value from an weapon component to a controller bluprint using interface and casting

the vector value in controller blueprint is 0 0 0

[oak fable]

should i do a and bool
so it will be
Direction >= 135 and direction <= 180
or
Direction <= -135 and Direction >= -180

that should work

[spark steppe]

no i think in your case the OR is fine

[oak fable]

it worked

[oak fable]

also the or is fine XD

[spark steppe]

also i would change a bit of that code

to cover all values, currently there are small dead zones of 1deg if i'm not wrong (again)

unless you want it like that

[oak fable]

there is not dead zones i believe

from 0 to 45, 46 to 134 and 135 to 180

[spark steppe]

45-46 are dead tho

[oak fable]

how

[spark steppe]

their range isn't covered!?

e.g. 45.5 will never trigger a dash

[oak fable]

got what you mean

[spark steppe]

that CAN be desired tho, but in a fast game i guess a wrong dash is better than no dash

[oak fable]

Xd

will try to fix it

[spark steppe]

use >45 AND < 135 for right dodge

and < -45 AND > -135 for left dodge

that will solve it without overlap

[oak fable]

so that wont be an issue with the forward dodge ?

[spark steppe]

no if you use < and > instead of <= and >= for the left/right

[oak fable]

thank you for the info

[warped swift]

hey 🙂 can someone point me to the right direction? learning ue5 and trying to figure out movement in topDown starter content and I'm trying to change that only certain place in level should be clickable -> in screenshot, with default movement, I'm clicking on the top of the pillar and I want it to change to the position behind the pillar, i.e. certain meshes in level like this pillar should not be clickable..

how would you approach this?

[gentle urchin]

Set pillar to ignore mouse trace channel

Or easier - create a new trace channel for the mouse, and activate it on the actors you want to block it

And set it as the mouse' trace channel

[warped swift]

I cant say I understand, but I will figure it out based on the tips, thank you! 🙂

[gentle urchin]

In the PlayerController theres a trace channel for the mouse

And creating new channels is done in the Project Settings

[loud bridge]

hey all - new to UE - i was hoping to have add navmeshboundvolume's around a spline in it's constructor, the best I can do is Add Child Actor Component and select NavMeshBoundVolume as the class. It does show up in the outliner, but doesn't show up in the editor, and it has no details page when selecting it in the outliner. Is there something fundamentally wrong with what I'm doing here? Should I go about this another way?

[gentle urchin]

I wouldnt add it to a spline in the first place

[loud bridge]

why's that?

[gentle urchin]

Especially not as a CAC

Question is whats the intent.. what do you wanna achieve

[loud bridge]

i want to achieve a navmesh that follows a spline that i can adjust on the fly

[gentle urchin]

Well the navmesh doesnt bend at all

So youd need hundreds of them to resemble a spline

[loud bridge]

right, i was gonna have to deal with that at some point lol

could i instead have some invisible walls spawn aroudn the spline that would act to block navmesh path finding?

[gentle urchin]

Yes

Easiest i found to work reliably was using isms

Theres been an update or two for thensplinemesh since the last time i did this, but atleast ismc work

Maybe spline mesh works today aswell,idk

Was huge issues with collision

[loud bridge]

never heard of isms but you may have given me enough to start reading - thanks!

[gentle urchin]

Instanced static mesh components

Pretty cheap mesh copying kinda thing

[loud bridge]

sweet sweet, thank you for the insight

[ancient basalt]

for refrence

[edgy forum]

just wanted to share an example of how helpful chatgpt is for learning blueprints! i've been using it for a month coupled with youtube tutorials.

[gentle urchin]

Ask it about using event tick

[red berry]

Does getcomponentsbyclass return a child of the specified class? The other similar functions seem to do, e.g. GetComponentsByClass/Interface/Tag but they return an array.
Edit: I think it does even though it doesn't say

[frosty heron]

it will just return the first component it found if you don't get it by array

[red berry]

I think thats a yes? It works for me when I do it. Not the end of the world since I can always use the array version and just get(0)

[frosty heron]

depends on what you want to do. if you need to get specific component, you can add tag to it and just loop through the array and get the one with matching tag

if you know ur bp only contain one of the comp u searched then it's probably safe to get the first one it found

would be an issue if you want to scale tho

Another alternative is to use interface

which is more clean imo

[red berry]

GetComponentByInterface is more cleaner? Would that even be needed if there's just 1 of the component?

[frosty heron]

https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Types/Interface/

at the end of the day is about knowing which tool to pick

which depend on the scope of what you want to do

[gentle urchin]

Its a yes

A child is an extension of parent

And thus also a parent

A child class is also a parent class. But a parent class is not a child class 🙂

Id just get component by class personally

Components are like interfaces with state capability

Interface is more for when you have a bunch of very different actors that you want to share some functionality with

Interaction being a common one

[manic hamlet]

Not really a 100% blueprint question, but is there a way to easily copy something thats in a folder in the outliner?
E.g. I made a city with 5houses,put them in a folder Town01, now I need these 5 houses in a folder in Town02......Back in unity i dupliacte the folder and it would make it just like that, unreal cant ....or im not aware of how to 🙂

[gentle urchin]

Drag assets over -> copy to here

[boreal valley]

Guys can someone help me? I have 3 levels in my game and when i am in my 3rd level, I created a box which if i go through, it gives my character 100,000 score. But when i die to the boss, i respawn into the 2nd level instead of the 3rd level

[manic hamlet]

drag from where to where? 😄

[gentle urchin]

From where they are to where you want the copy

[manic hamlet]

that doesnt work(im hovering Town2 folder here, mouse goes away unfortunately) 😄

I marked them....started dragging ontop of "town2" and theres no menu or so, if i let lose it will just move them.

[gentle urchin]

Ohhhh

You want to duplicate them ?

Group

Hold ctrl

Drag

Get a grouped copy

Move to folder

Ungroup

I thought u were in contenct browser not the outliner 😅 mb not reading

[manic hamlet]

haha no i mentioned outliner specifically, i know how to copy files lol 😄

[gentle urchin]

Yepp, thats the me not reading part 😅

[manic hamlet]

the holding ctrl part does nothing after grouping

still getting the "move into town2" thing

[gentle urchin]

Ctrl and drag in viewport

Not in outliner..

Just like you dupe instances regularly
Could be shift or Alt instead, not at editor so cant verify

[modern radish]

I'm trying to make an asset move when something triggers it, I was instructed to try VINTERP, but it doesn't seem to work, any ideas?

[manic hamlet]

ah okay, Yeah ive been actually doing it(without the grouping) you proposed(its alt-drag^^) I assumed it would be as easy as in Unity and just ctrl+d or so.... well okay, finally can say i found one thing thats worse in unreal than in unity after almost 10month of learning UE 😄

[gentle urchin]

Was this so bad?^^

Group -> copy -> move in folder -> ungroup?

Probably some shortcut for direct duplicate aswell that im not aware of^^

Mayje ctrl c + ctrl v works in outliner? Dunno

[manic hamlet]

Well in Unity its literally...click on folder...ctrl+d and everything is copy pasted 1click +2presses of a button 🙂
Unreal way is at least 15+ actions so its worse 🙂 Ofc it aint the end of the world, just saying thats worse in UE than Unity ^^

[manic hamlet]

nope,tried that 🙂

[gentle urchin]

15+? 😂

[manic hamlet]

I assume there would be something like that.

[gentle urchin]

Anyways

Not something i use often (ever)

[manic hamlet]

Ye.... right-click folder->click "select all descendants"->group->copy->make new folder->ungroup etc 😄

aight more closer to 6 actions i guess ^^

[gentle urchin]

😆😅

10 if every click counts

[manic hamlet]

either way, worse than ctrl+d..thats my point

[gentle urchin]

Ye i guess

Could check shortcuts list

To see if theres some magic buttons

It may even be just not bound

[manic hamlet]

I dont use it often either.... I just made a "small town"-template and made a "big town template" and just put them in the world as placeholders for now. so that I can map out the open world were creating

I didnt want to just use block/rectangular blocked white things there, I like it if it looks nice already ^^

[wild crater]

I feel like structs in BP aren't super user friendly, or at least I'm less inclined to make a struct when working in BP than when working in C++. To get one variable you have to split the entire struct. Do you guys add getters to structs or use data assets in stead sometimes?

[gentle urchin]

Grouping also helps for this^^

[gentle urchin]

Avoid bp structs in general

Risks entire project

[modern radish]

Is there a way to Make a Material node DistanceToNearestSurface ignore a specific mesh? If I understand correctly that relies on a mesh distance field, but how can I disable a mesh do that it's not picked up by that node at runtime?

[frosty heron]

you can hide unconnected pins to keep it tidy

[wild crater]

How so?

[frosty heron]

bp struct can corrupt your project easily. Does a lot of nasty stuff

[wild crater]

Yea I know, but it usually leaves a few pins open still?

[frosty heron]

declare them in C++ and you are good

[frosty heron]

no?

[gentle urchin]

Ton of internal voodoo that can be corrupted

[wild crater]

Really?

[wild crater]

Last time I tried. But I'm in 4.25

[modern radish]

What do you mean by BP Struct? you mean regular structs?

[frosty heron]

means struct that is made in blueprint

instead declaring it in C++

[wild crater]

That's also what I meant

But regardless of that. Getting data from it in BP remains a bit cumbersome.

[gentle urchin]

Yepp

[modern radish]

okay, but Structure Assets are fine?

[wild crater]

And setting by ref

[frosty heron]

@modern radish This stuff is super cursed

no project should have it ever

[modern radish]

shit my game relies a lot on this now

[gentle urchin]

Id rather use an instanced uobject

But then theres replication

[wild crater]

Ah okay maybe the break node offers more options than when it's an output pin on a function!

[modern radish]

But that's so strange, we use it at work a lot IIRC

[wild crater]

well that's a good adjustment I could make already

[manic hamlet]

dont worry i got worried now too cause i use structs A LOT too 😄

[frosty heron]

what work? It's a very common Known issue

[wild crater]

What about data assets in some cases?

[frosty heron]

Blueprint struct is probably the most hot topic when it comes to bugs

there are people not being able to package or have their defaults reset almost on a weekly basis

[modern radish]

Do you have any sources saying we should avoid Structs at all costs? I can't find anything online

[frosty heron]

I didn't say avoid structs at all cost, I cannot live without structs

what you need to avoid is BP structs

structs that are made in BP instead declaring it in CPP

[wild crater]

How can they be so different though?

[frosty heron]

a quick google will show you countless people crying over bp struct

[manic hamlet]

I mostly have issues with structs in WidgetBlueprints though.... each time I start the engine it tells me 2or3 "lost their connection" and i gotta "redo them" (simple refresh node does it though^^)

[frosty heron]

#blueprint message

[frosty heron]

Nothing to do with widgets or non widget blueprint

you just haven't hit the minefield yet

[manic hamlet]

prolly 😄

[frosty heron]

and I consider you unlucky for not stepping into it earlier

[wild crater]

What are you referring to here?

[frosty heron]

because I been a victim and I don;'t want to be a victim anymore

[gentle urchin]

They're singletons tho arent they

[modern radish]

but all I'm doing is storing variables on Structs, and reading them inside BPs

[manic hamlet]

gotta learn another way in the future then, for now I go with it as were still pre-Prototype 😄

[frosty heron]

regardless you shouldn't use bp struct. even adding new element or re-ordering them will destroyed your project

it's been a decade

[wild crater]

You mean you'd lose data?

[frosty heron]

and still the same issue

[modern radish]

My structs are created dynamically every time the game launches

[frosty heron]

You can't package, default values get reset, etc, etc

[wild crater]

Uhm what? You can make multiple instances of a data asset

[frosty heron]

Unknown struct error is one of the common error

[wild crater]

That's so crazy though. I'm working on an almost blueprint only project and there are many structs and this issue never arose

it's also the first time I hear of it

[modern radish]

Same here

[frosty heron]

🤷‍♂️

[wild crater]

Maybe you're misusing structs somehow? But for base use cases they never let me down

[versed sun]

Same here, untill it did....

[wild crater]

Besides the fact that it's a bit cumbersome to create an asset for a simple struct

[wild crater]

well fuck ^^

[modern radish]

Okay, but I think it depends a lot what you do with Structs then? Apparently adding variables to them while they are being used can cause issues, from some google research? But in my case I have the Bp Structs setup, it's empty, and they are populated at runtime. and I only ever read data from them

I can't see how it could go wrong

[versed sun]

Ooo, my struct needs a bool, annnnd its broke

[gentle urchin]

Really? Ive always considered them static singletons

Instanciated by the engine

[frosty heron]

You can stick using it and risk corrupting your project but don't say you are not warned

[wild crater]

Well I haven't looked into how they work, but I look at them as a way to create content through data. For instance I have a recipe to populate the shop in the game and different data assets represent the different recipes.

[gentle urchin]

Right but its just one datasset

Unless you instanciate it yourself

Which kinda defeats the purpose ?

[wild crater]

Oh like that

[tough atlas]

I'm using the Physics Handle component in my game and am trying to stop players from prop surfing, my current idea is to freeze the player for a split second if their movement exceeds the sprint speed.

Anyone know how I can use Character movement velocity x y to calculate a speed?

[wild crater]

So you're saying one data asset of a certain type is a singleton?

I haven't really looked at how it works under the hood

But it does what I want it to

[gentle urchin]

Yes, thats how ive understood it

So if you alter the data, it will be altered on all references to that DA

[wild crater]

Speed is the magnitude of velocity. So just get the length of that vector.

[gentle urchin]

Unless you manually instanciate it

[wild crater]

Okay. But that would be the case when referring to the same object too? The way I interpreted it is that it's an instance of a DataAsset class that exists at edit time. Well even all the time because it's an asset. But when you're referring to it, you're referring to instance of a subclass of UPrimaryDataAsset

Not sure if you'd need the singleton pattern to achieve this

[tough atlas]

What component do i get vector length from?

Not sure how to get it

[wild crater]

In fact it sounds rather cumbersome because that implies it would need to generate code? Rather than just generating an instance of an object containing whatever data is in the asset and having everything refer to it.

[frosty heron]

Character Movement Component -> Get Velocity
That's your speed

[wild crater]

If you have a vector you can just get the length from it. If you just have the two floats, you'll have to make a vector from them first. You might want to consider studying some vector maths though, it's so essential.

[tough atlas]

figured it out alg

thanks

[gentle urchin]

Yes exactly, just like a pointer to the same object would

And since its just a single asset (uobject), its not suitable as a mutable set of variables...

Unless you obv wanna share it (which i do in one project)

Structs are initialized when they're decleared in bp as its own instance and can thus be mutated related to its owner ....

Dunno if i make any sense at all

But bottom line is, unless you instanciate the data-asset yourself, its not a suitable replacement for a struct

[frosty heron]

make perfect sense, Data asset is not a replacement to struct by any means. You can create many instances of the struct each holding their own set of values.
try to do that with a Data Asset lol

[gentle urchin]

You can prob construct object from dataasset class to do the same

But its very meh

Would be the same with uobjects aswell. Its very meh.

[frosty heron]

true but yeah :S

[torpid juniper]

So just reading what has been said. Structs in BP are bad? Is there an easy way to change them all to c++?

[gentle urchin]

No easy way, just the 'do the work' way

[torpid juniper]

ah, fair

Also, how do i even make c++ scripts when the project is in bp?

[gentle urchin]

Its not exclusive

You can at any point add (another) c++ class to the project

[frosty heron]

Tip to help with declaring the struct in cpp

[torpid juniper]

as right clicking doesn't show any option to make script

[gentle urchin]

File -> new c++ class?

I cant recall were we do it initially.. not at pc

[tough atlas]

@wild crater So I set this up and the issue is that while I'm prop surfing the velocity is coming out as 0, even though im moving at thousands of speed units

[gentle urchin]

(As my typing clearly shows )

[torpid juniper]

ha ha, fair. Thanks. will look

[frosty heron]

Tools -> new c++ class

[tough atlas]

I think i need to get the world location of the character in one tick and compare it another tick later, if the difference is greater than my max allowed i drop the physics component to stop prop surfing

[torpid juniper]

Wait, can you make an instance of a data asset?

Like if i have a data asset for an item that is a chest and i want it to hold items

[gentle urchin]

I believe you can yes

But you gotta manage that one yourself

[torpid juniper]

Or whats the best way to go about doing that. As currently my plan was to have data assets for each different item in the game based on what they are. So i have a primary data asset which is furniture and then one under that called storage which has some extra variables for num storage slots. And all those data assets are of type item

So my inventory says i have 3 of a reference to "chest item" and when i place it, i want it to then be able to have its functions and stuff from the data asset and be able to look after itself and have storage and stuff

[gentle urchin]

That's where the issues come in

[torpid juniper]

Or is it better to create actors and add components to them in the process of placing

And give it any details it needs to know about being a chest?

[gentle urchin]

as it's singular, unless you've instanciated it yourself (which still wont give it physical rep), it can't really hold any state

[torpid juniper]

Yeah. Sweet

[gentle urchin]

To get around this, and keep data assets what they are, static data lookup,

[torpid juniper]

time to look that up 😅

[gentle urchin]

It's not a good idea x)

[torpid juniper]

static data lookup isn't?

[gentle urchin]

That part is

[torpid juniper]

Would the actor thing be better?

[gentle urchin]

but when you'd spawn it, it has to be an actor

that actor can have a ref to the data asset,

but the data asset cant , and shouldn't, really manage any state holding what so ever

that's the actors job

[torpid juniper]

Yeah, sweet

I'll have it so when you "place" the item that it will spawn an actor and give it components it needs to be a storage container and pass the values from the data asset

[gentle urchin]

(or pass the data asset)

instead of the values

as that's far more effective

[torpid juniper]

and have a ref to the item it is so when you break it, you know what data asset to pick up

[gentle urchin]

if we care about that in bp world

[torpid juniper]

ha ha ha

true

[gentle urchin]

Im doing some of the same stuff for my quest system

QuestBase is dataasset

thats static data

[torpid juniper]

Yeah, so that will contain the rewards, who you have to talk to and such?

[gentle urchin]

QuestInstance is an instance of a quest, with QuestBase reference, and whatever i need to track its states

[torpid juniper]

all the text for it?

Yeah, i probs need to remember how to code in c++ again as its been a while

[gentle urchin]

so whatever setup im doing is done in the data asset

it has its own uobjects with the fancy EditInlineNew / Instanced property

In theory you should be able to do something similar for your furnitures and whatnot

[torpid juniper]

That picture is from the data asset right?

[gentle urchin]

Where you have a main Item Definition, and Item fragments, which expands on the base item, and adds further functionality

[gentle urchin]

yes

[torpid juniper]

Yeah, ok

My current plan is for the data assets to contain their own recipes as well if they have any

[gentle urchin]

multiple?

[torpid juniper]

So will have some sort of layering like that

[gentle urchin]

that would also be a uobject

[torpid juniper]

Undecided

[gentle urchin]

'recipe'

just like my rewards

since i dont know what a reward is at this point, i've just made the base class extendible with blueprints

keeps it flexible for whoever wants to use this
