Just change the rotation, delay .01, check to see if W is still down, If true plug back into the change rotation

inner igloo
#

Do I use a branch for that?

#

I mean for checking if W is still down

mellow folio
#

Yeah

inner igloo
#

So this ended up working

#

But I don't understand why it works lol

#

When I didn't have the delay, it crashed, but when I added the delay, it succeeded?

#

I'm not sure how that works

mellow folio
#

You forgot to plug the condition into the branch

inner igloo
#

Ya I got it

mellow folio
#

You needed something that Introduces time

inner igloo
#

I don't know if that's the best way to do it but it's working as I want it to

mellow folio
#

While loops do not do that

inner igloo
#

Oh

#

How do I make the equivalent of a delay to a frame passing?

#

Would I put world delta seconds in the duration of the delay?

#

Ya that seemed to work

#

Ok I think I'm getting it

#

Thanks for your help. Blueprints seem really... confusing lol. The logic of traditional coding is there but the execution is way different it seems

#

I'm mostly learning Blueprints because I want to see if it can help me form ideas into code faster than just coding traditionally

#

And also if I want to get others to help me with my projects and they don't know coding, I'm hoping BP is easier for them to grasp so they can help with a bit of coding as well

#

Anyway I'll keep working with BP. I think the hardest part rn is translating what I know from coding in C# and JS and try to translate it to this

Hi, is there a quick way to get the player actor associated within the player state? or I need to manually store the actor reference in the PS on possess

#

Also I think it's ridiculous how I can't undo after compiling code, but w/e I'll try to compile less often

#

What do you mean by fighting race conditions? Sorry still pretty new to game dev

odd ember
#

race conditions is when you have an arbitrary starting order, and two elements that are dependent on each other have to wait until the other one is available

#

"race" comes from the idea of "who will get there first"

#

for instance, if you have one actor that has a reference to another actor, and needs to use that reference on beginplay, but the other actor hasn't spawned in yet (we're talking frames of time here), then that would be a race condition as the reference would return null

#

so a quick hack to ensure both actors are spawned and ready is to put in a delay by e.g. a frame

#

the correct way to do this is to have the other actor register itself to the first actor on its arrival

#

or, alternatively, have the first actor spawn the other actor

inner igloo
#

Oh I gotcha

#

For my case with using delays as a means of looping through checking the w key, it wouldn’t matter if I used world delta time right? Since the floor actor is always present and spawns when the game starts?

odd ember
#

using delays with loops doesn't make sense

#

if you're looking for something to execute at intervals, use a timer, a timeline or tick

inner igloo
#

Ok I’ll have to look into that

#

I think it’s a lil different here since when I programmed in Unity I put most of my stuff in the update function, so the ticking was taken care of for me. Here in Unreal it seems a lil different but maybe that’s because I’m still trying to understand BP syntax

vague dome
#

can anyone see a reason why this would not work? The event runs on owning client but it fails to add the widget to the screen

unknown.png
#

its getting called in the pawn, and added in the playercontroller

odd ember
inner igloo
#

Oh interesting

#

I’d rather use something that stays in line with the frame count

#

So I guess timeline would do that?

odd ember
#

timelines update values based on tick, and are usually used with an alpha value lerp to move something over time

inner igloo
#

Oh ok

odd ember
inner igloo
#

Oh ok

odd ember
#

you can use timelines as well if you really want to, but it's a bunch of extra setup for something you might not need

inner igloo
#

So when you say “tick” are you referring to Event Tick

odd ember
#

yes

inner igloo
#

Ok

odd ember
#

in BP, events are functions without a return value

#

so think void

inner igloo
#

Oh ok got it

#

My main issue with my prev problem was getting UE to read keyboard input each tick, but couldn’t get that to work with both Event Tick and the W key press event

#

I’ll have to try again tomorrow with using Event Tick

odd ember
#

is this for multiple keys being hit at the same time?

inner igloo
#

Yea

odd ember
#

you don't need to poll for that

#

you can just check if the other key is being hit at the same time as your first key

inner igloo
#

Oh sorry what I mean is if keys are being held down

odd ember
#

right okay

#

yeah in that case you'll have to poll somehow, unless inputchords work in this case

#

I've not used those however

I've been looking to re-create a music control system that I saw a YouTube video about. I pasted the files into my project, and realizing that I couldn't use them in that state, I saw to recreate the process piece by piece. I copied in a Struct it uses some time after creating a possibly identical Struct of my own.

#

While building, I noticed this little oddity

Set local rotation

Unfortunately it seems there is no “SetLocalRotation” node, and the only way to rotate an object on it’s local axis is to use the “AddLocalRotation” node. I want an object to match the Z value rotation of another object, but to rotate on it’s local axis instead. Niether SetRelativeRotation or SetWorldRotation seem to work this way. Does anyon...

Yeah I'm not seeing anything specifically with the code you've shown that would throw that error. You've validated the variable already, and if it is invalid, you're populating it, so it should be functioning ok.
This is where the error message directed you to when you clicked on the "Ubergraph BP_Base_Player_Controller" link?

hey yall i was looking to get some help on my lock on system

#

this whole mess of things is what i have and whats happening is that it locks onto the closest target, whether you can see them or not

and was wondering if there was a way to make it so it would only lock onto ones in view

dawn gazelle
# glass magnet hey yall i was looking to get some help on my lock on system

Instead of getting all actors of class, you could do a multi sphere trace within a certain radius, then from the hit actors you can loop through them, check if they are the correct class, if they have been recently rendered, and if so, check their distance to the player's character etc. as you have near the end here:

unknown.png
torpid mulch
glass magnet
dawn gazelle
#

Sphere trace around the area of the player within a defined radius (ie. the range in which you want the targetting to work), and those hit results, check class, rendered, and distance for closest.

glass magnet
#

for sure and would it be a multi sphere trace by channel?

dawn gazelle
#

Any of the traces - whichever works best for you. for Objects could be used too.

#

Just as long as it's a multisphere trace

glass magnet
#

why multisphere

dawn gazelle
#

It returns multiple hits.

glass magnet
#

I'm trying to get the targets in front of player

#

a sphere sounds like the same thing to me

#

im sorry im confused

dawn gazelle
#

One only gets a single hit the first thing hit. The other returns a whole bunch of hits.

glass magnet
#

ok but if i change it to multisphere i cant check if its the target with the specific class

dawn gazelle
#

Recently Rendered allows you to check if it's within view of the camera.

glass magnet
#

it doesnt really fit as i am not able to check nearest target without the actors of class array

dawn gazelle
#

The hits are what is telling you the object and the distance.

grizzled peak
#

why can't I transform a static mesh inside a construction script of a blueprint? i can't use offset or transform or location nodes to modify the placement at all.

glass magnet
dawn gazelle
#

If you want to check for anything directly in front of the actor, that'll require some kind of comparison of the location of the target and the forward vector of the actor. Probably some kind of dot product, but I'm not sure of the math needed myself.

faint pasture
#

@glass magnet Datura is right. You want to sphere trace or get overlapping actors on a sphere collider, then filter and select from the results however you want.

glass magnet
#

even for in front of the character

faint pasture
#

Yes

#

Use the dot product to filter out objects in a cone

Has anyone made an edit system for structures? I have an idea about using object states to load different models based on the edit selected.

My main question is, during model selection i capture which object the cursor is over, hit "manipulate" that brings up a "grid model"

how do I make sections of said grid selectable ? Once the selection is finished the state check would happen and load which ever version of the model correlating to that manipulation.

Would I make an object model of the grid in Blender and animate ALL different combos per piece?

Since I have a neutral (none selected) , selected phase, and a messed up (incorrect selection phase) would each of those need their own model?

faint pasture
weary ridge
# faint pasture Like buildings?

Either buildings or walls, stairs , think Fortnite layout. I want a game thats basically only building and none of the other stuff but Fortnite is missing a ton of shapes that I want so I thought I'd make a system that transfers my building/editing to a new game

faint pasture
#

You'll have to make all that. I'd start with some sort of a grid and actors or meshes on that grid.

#

It's basically the same as a tile system but in 3d

weary ridge
#

So would the grid be its own mesh? and each phase be its own mesh? or

#

a tile system , didn't know thats what they're called

faint pasture
#

No, a grid would be abstract.

#

You'll want to start from the very basics. Start by making a mode to place cubes, where you can only place them at 100 unit increments

#

In fact start with just pressing a button to spawn a cube, then make it align to the grid

#

Then add other options rather than cubes

weary ridge
#

Yeah I know that. I'm talking specifically about the edit part

faint pasture
#

Then add other grids based on the nearest "structure" or whatever

faint pasture
weary ridge
faint pasture
#

Yes I have.

#

Are you asking how you'd do a building mode?

weary ridge
#

No, just the edit phase

faint pasture
#

Explain that because I still have no idea wtf that means

weary ridge
#

Have you ever edited a wall in Fortnite?

faint pasture
#

Played it like once.

#

Anyway just describe what you're wanting to do.

#

Edit an existing structure?

weary ridge
#

ah yeah that makes more sense

#

yeah

faint pasture
#

I mean it's pretty simple. If "editing" just replaces parts then remove old spawn new part. If "editing" changes stuff like color or size of individual parts then just make some interface to enable that across all the buildable meshes.

weary ridge
#

but there's a phase in between so for simple example, a floor is placed , hit manipulate and a 2x2 grid appears.

How would I make that grid and make it react to mouse selection

#

idk can I post a clip here?

faint pasture
#

Or some post process shader stuff

#

Can be anything really.

weary ridge
faint pasture
#

You need to come up with some function to determine where in 3d you want to consider the highlighted "cell" is.

#

That's all up to you. Fortnite probably does some sort of sphere trace to determine where in 3d it considers you to be aiming

#

You already need some sort of function to decide where in 3d you're aiming for any part of a building system. Start with that.

weary ridge
#

I'll just wing it after I get my animations rendered and go from there. I know I'll be back with a ton of questions as I'm just understanding logic and watching tutorials.

my big concern programing wise is I want to use a lot of if statements which I'm sure is not effective

faint pasture
#

Just make sure you understand 100% exactly what and why you're doing what you're doing when following tutorials. Learn to paint, don't paint by numbers.

weary ridge
#

if I didn't want an edit ability I could just have a huge library of parts for all of the edit types , but that isn't fun

torpid mulch
#

Do we have this but for components?

unknown.png
glass magnet
#

what kind of component

faint pasture
torpid mulch
#

I'm kinda lost to be honest, I wanted to set the location of the component on a "offset" way, keep track of the parent but with certain distance, but whenever I use "Set World Location" the object gets stuck on the vector location of the world I set.

If I get the location of the parent and add the offset, the component flies away as the amount keeps being added.

weary ridge
# faint pasture If you make a building system you'll pretty much have the edit system right in f...

For the building system its way different than an edit system. But I think if I use the grid mesh and figure out the color option it'll work.

Because when you go to edit say a wall, the wall model vanishes and instead an edit grid is displayed (assuming its the model ) , what tiles you select would be saved as a state, and that state just loads the new model piece.

actually making the edit grid will still be an issues.

as far as assets no I have 0 because I want my pieces and textures based on carbon fibre and exotic materials (realistically could make a rectangle and replace the object later)

spark steppe
#

@torpid mulch theres set world location and relative location for components

#

relative is an offset from the parent, so if your actor is at 10, 20, 30 and you set the relative location to 0,0,0, the component will also be at 10, 20, 30

torpid mulch
#

So basically relative location would work like the "local transform" on Unity? (just for example, as I'm recently changing from Unity to Unreal)

spark steppe
#

most likely yes (idk about unity tho)

#

so i guess that's kinda the same

#

the same exists for rotation

torpid mulch
#

I'll try it right now, you probably just saved me tbh, I was trying to discover how I could achieve that for a long time, thank you so much!!!

spark steppe
#

keep in mind that if you have a spring arm between the camera and actor, that the spring arm may also introduce some offset

#

so with a spring arm it can get kinda fiddly

gentle urchin
#

i like spring arms

#

they're nice

torpid mulch
#

Oh I don't have it, the camera component was more of an example

spark steppe
#

yea, they are indeed nice, just saying that because i struggled a bit on those as beginner 😄

gentle urchin
#

giving you a free socket, auto rotating relative to its core rotation etc etc ^^^

torpid mulch
#

It works perfectly now, thank you so so much 😄

Is there a way to add more 3d widgets with a construction blueprint than just what you premake as variables? Do I have to add child actors or something?

#

Simple example, I have a blueprint where I want to have a start and end widget which will will place static meshes between the 2 points. Could I make it so I can add more rows with their own start and end points adding new control 3d widgets

astral epoch
#

You could set the variable as an array/list so you can dynamically add and remove them?

zenith pond
#

Ahhh forgot arrays do widgets

astral epoch
#

Arrays work for most, if not all variables that I'm aware of.

#

I don't know the expense of doing that mind you, but I use it for storing several characters in a single controller if said controller is meant to swap between them.

hi, so i have a problem where my character would lock onto nothing i thought it was a minor thing, i sorted that out. but then i made a compass with some objectives, you can see the objective on the right but the compass is showing the exact same area as what i used to lock on to. Ive looked at this area and there is nothing there on the map. If anyone could help me i would appreciate this and let me know if you dont understand this, i cant really explain it well. https://gyazo.com/f6295ef3a480d52efb4dd77e66cbd940

# undone surge how do i get these 2 metal and roughness params

You make them. Press 1 in your material graph, then rightclick on it and convert it to a parameter, then name it "metal" or whatever you want.
Or you can click S to create a scalar parameter directly.

This is a better question for the graphics channel though.

undone surge
#

thank you

teal dove
hushed gazelle
#

but its doing the exact same thing for my compass too

#

thats what im confused about

teal dove
#

If you go through the blueprint for the compass and the character, there should be a part that tells the character & compass to lock onto something. So my best guess is that there is an error in that part, where it does not feed the correct location into the lockon function.

#

You can take a screenshot of it and show us

hushed gazelle
#

thats the position of the points for the compass

#

thats the lock on

teal dove
#

Why are you using a spheretrace for the lockon?

hushed gazelle
#

tutorial, i didnt know how to do it

teal dove
#

^^ what do you want to do exactly?

hushed gazelle
#

wdym

teal dove
#

So I can see if I can simplyfy / fix it

hushed gazelle
#

itll show that

#

so u can see that my object is on the right, but on the compass its fixed on a point thats right in front of me

#

idk why it does that

teal dove
#

the object is that glowing wire thing?

hushed gazelle
#

yeah

#

no matter where i put it, it will still fix on that point

teal dove
#

And you want your character to always face where that glowing thing is on the map?

hushed gazelle
#

no no

#

its just a compass

#

its hard to explain

teal dove
#

aaaaahhh

hushed gazelle
#

without showing

teal dove
#

So that thing is an arrow that should point into the direction of an object?

hushed gazelle
#

yeah, the icon should be fixed on where the object is

teal dove
#

icon?

#

You mean in the compass?

hushed gazelle
#

yeah

teal dove
#

ah okay, so 1. the arrow in the world should point to the objective direction & 2. the compass icon should do the same?

hushed gazelle
#

no no, just the 2nd one

#

could i add you and could we maybe take a better look in a call at 11.30?

#

ive got a meeting rn

#

"Character" in both cases refers to the character holding the gun, of class Abs_Character

#

This is in the abstract gun blueprint that other weapons will be derived from.

#

Reason for Physics Assets is that I think having one on while attached was causing physics stuff to happen to the character.

odd ember
#

set simulate physics should make detachment happen automatically even. my take is that this is a replication error given it's multiplayer

#

also detaching "self" does nothing

Okay I'll try just the simulate physics.

But yeah might be some replication nonsense going on. Still trying to figure out how to use it properly.

Okay simulation didn't help. I'm almost tempted to just destroy the actor being held and spawn a new one but I know that isn't exactly the best way to do this.

odd ember
astral epoch
#

Aye. I think modern processing is probably good enough that the spawning/deleting of actors isn't too bad. It will be on weapon drops, so either a character dies or a player picks a weapon up... so its not like its going to be dozens of times per second.

Afternoon all, does anybody have any experience with getting dynamic physical material output from line traces from landscape automaterials? Trying to use the 'Landscape Physical Material Output' with no luck 😦 Tried a few things but doesn't seem to be working, just returns 'default physical material' even though I have all assigned in the node

Hey guys! I've a problem. I've build a blueprint that switch a combination of meshes with a parameter.
I've animated this parameter in the sequencer timeline, and if I scroll the timeline it works, but if I launch a render the meshes don't update.
I have to attach the construction script to a specific event to render this mesh switching properly?

Thank you"!

Are you tracing up to the wall, or past it? If you're tracing the wall, you're up to float precision errors on whether it'll hit or not. If you're tracing past it, you have a settings or collision primitive problem.

devout geyser
#

up to the wall

maiden wadi
#

Yeah, you need to add a slight amount to that. Tracing to the wall is nearly like trying to directly == a float. You're gonna get some crazy results.

Guys, when doing a LineTraceByChannel, the 'Blocking Hit' or the 'Initial Overlap' says there is something colliding with the LineTrace? I want to trace below my character to verify ground distance, but I'm not so sure. (I'm a newbie on unreal lol)

maiden wadi
#

The trace node itself will have a boolean output. It will be the same as breaking the hit struct and getting the BlockingHit boolean. Either of them mean that the trace hit something.

nope 😦

#

level map game

#

think it might be world but you can't easily do a world soft ref in a level actor.

maiden wadi
#

Is this UE5?

green eagle
#

First you have to go and get a "load map/level" node > click and drag off the input and > "promote to var" that will give you the "world soft obj ref var" then you use it for what ever you needed it for

#

You can't create a world ref var otherwise

green eagle
maiden wadi
#

Because at least up to 4.27.2, you cannot get a UWorld SoftObjectPtr without the right click promote to variable hack, which also breaks fantastically in some cases.

that was a fun little adventure for the day

One way or another I'm no closer to a solution sadly

gentle urchin

basically you must do it yourself,

#

there's no replication for this

crimson saddle
#

Yeah that's what I've been trying

gentle urchin
#

So why no bueno

#

creating it on the client should be identical to the server, should it not

crimson saddle
#

Running the instructions on each client without replication, but for some reason nothing appears for clients

crimson saddle
#

It does work on the server though so I'm not sure what would be preventing the clients from doing their own local stuff

gentle urchin
#

sorta makes me wonder what this mesh really is in the first place, needing to be generated on each client

crimson saddle
#

Attempts at mod support, basically custom user files

gentle urchin
#

Ah

crimson saddle
#

Theoretically everyone has the mod downloaded so they have the mesh and just need to load it

#

For whatever reason it isn't applying on clients

#

I'm hoping I can find someone who has done this sort of thing, because everything I've found is either totally out of date (before the component was in the engine) or is just another post that eventually links back to that other link.

maiden wadi

@crimson saddleI would start by doing this at an actor level to begin with. Disable any component replication. Start with no networking and have clients generate a mesh on beginplay. This should work. Next find the way you want to specify the mesh to clients unless they can infer this data on their own from some other way. There is generally never going to be a reason that clients can't do visual things like this on their own.

Hello! I have a save system implemented to our souls-like game where upon reaching a campfire, the player data (Such as location, level map, HP, etc) is saved to one of three save files. When quitting to menu and opening the save file, all of the data is soundly restored and ok. This will work as many times as you try in the same session.
Upon quitting the application and reopening the game, the save system gets corrupted and the save files are inaccessible and result in crashes.
I have a few different blueprints working together in this system, so it'd be a lot to show in screenshots. But I have a SaveGameObject that holds this data and for some reason I cant figure out the final step of relaying the information back into the file.

Realistically, you could get away with very basic functionality of a 3D modelling program and create meshes and modify vertices in real time, but eventually, with large amounts of vertices and all kinds of math you'd have to start using C++.

Making procedural meshes even with just primitives is already a difficult task in the demoscene realm (especially with size coding where you have to make your own 64 KB engine)

Tips for Improving isometric view

As you may know, we are currently working on ROTE Revolution, which is a 3D game with an Isometric camera and a top down view. In this new version we decided to add 3d elements and sceneries to our puzzle. That idea looked cool, but little did we know that we were running straight into…

If you're talking Dota style creeps just spawn them on a timer

On creep death -> X Delay -> Spawn new random creep

#

the invisible option is viable in this case i think

odd ember
faint pasture
# runic parrot On creep death -> X Delay -> Spawn new random creep

If you do it through the spawn manager you'll probably want something like a queue of upcoming spawns.
A death state might be simpler but you'll have some weird edge cases like if some mechanic deletes the creep like conversion or whatever. Depends on the game design but it's fragile.

#

Or if it falls off the map and hits the killz or any of a million other bugs

#

I would just do
On Destroy -> notify manager
and let the manager sort it out

runic parrot
#

Yeah, i don't want to keep the creep alive if posible because it's referenced in various places.
I'm just gonna do an array of vectors with death time and go in order

Hell, Dota just checks for occupancy on a timer and calls it a day lol

that's where camp stacking came from

nah Dota's an infinitely better game. Was probably an engine restriction from WC3 days that became a mechanic

Sounds lazy to me : P
Lol made his own engine

odd ember
#

the other thing you could do is spawn an object that sticks around just for the delay to trigger

and then sends a message to the spawn manager

but it's less elegant than using the spawn manager directly

Hello, I'm trying to make a game where there is a FPS-like character. (move, shoot, aim), come of them are player controlled, and some I would like to directly control with specific "button presses" mimicking the player character. So if the player character moves forward, the AI bot does, etc. I basically spawn in an AI actor with a null/void behavior tree, and then call the movement functions manually. I've gotten this to work with 'button-like' inputs, like move, jump, shoot, but I'm having trouble with aiming controls. These are tied to the functions like AddControllerYawInput (https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Pawn/Input/AddControllerYawInput/) And they just Crash when called, and the player is not possessing that character with error: "Accessed none trying to read property ControllerRef" -- is there some other way to directly emulate this kind of aim setting that doesn't use this function?

Guys, I'm trying to do this work, I have set the collision overlap correctly, but when my character overlaps the object nothing happens. Does the collision inside 'PlayerController' have to be the root object?

My PlayerController component collision type is set to Pawn, and the object that should receive the overlap (from the screenshot) overlaps to Pawn and has Query Only as collision type.

You don't do collisions in the PlayerController

My bad, as the name of my player blueprint was "PlayerController" every time I used PlayerController for things, Unreal was thinking it was its own controller blueprint, the one used to input. Now that I changed the name fo my blueprint it is working on all the methods you mentioned

#

Thank you so much for your help though!!! I appreciate all the interesting methods to make it work! When you mentioned just verifying with the equal, is it better on performance?

dawn gazelle
#

Well, it's not really about performance - it's such a tiny small difference in this context it doesn't really matter. It's more a matter of you're comparing the "Other Actor" to make sure it's actually the player's possessed character. When you're doing a cast, when it's valid, it's just telling you that it's the right class, but it's not necessarily the player's character.

Let's say for example, you had the player's character using the same class as other actors in the scene and used a cast method instead - then any of those actors could trigger that overlap.

Is there a way to get the default values of a component from a class that has those components added to it?

I'm trying to optimize dev time by being able to create a block "object" (for example) that has multiple components added to it (potentially several hundred) and the easy way to do this is to create each one in the editor as though it is its own stand alone actor.

I'm then looking at going through each of these actors and pulling the data from them and then turning them into instanced static meshes dynamically, adding in equivalents to each component (some of which will run code).

Is there a way to do this without instantiating at least one of each actor? I may also find myself with the need to instantiate the actors as actual objects though that would be at least somewhat limited.

#

Oh, and for performance reasons, just creating a new instance of the actors isn't viable. I'm looking at potentially instancing many thousands.

surreal peak
#

You can grab their default object if you only need to read data

#

The class defaults in BPs are however a bit limited

#

So you might need to expose the actual default object via a small CPP function

#

If you need to modify those instances then you gotta spawn them

#

If a few thousand are needed you might need to start pooling them

The pre spawning is also runtime but usually at the startup of your game, hidden behind a loading screen

But I'm still not sure what you are actually trying to accomplish

But the vehicle itself is a actor in the scene right?

But they are also just objects, so no components allowed. Would only allow for variables and functions.

subtle blaze
#

Yes but each vehicle will be made of up to several thousand parts and said parts can be interchanged by the player.

Think legos as parts so most parts are simple.

surreal peak
#

Right. Yeah then try it with the CPP class defaults to get your hands on the components of the actor bp

Just don't modify that :D

Hey guys. i'm makeing a VR bow game. so far so good. but now i'm trying to implement some target practices at a shooting range giving points on how close to the center you hit the target. in most cases it works great but looks like if i hit some specific place the hit location gets set to the origin of the target actor any idea why this is?

You could also probably do it via some actor that hooks into dispatchers. Really depends on what you're after.

#

Elden ring is doing fine and you can just walk past the tutorial. I wouldn't bother rearchitecting my entire system to support "pause and wait for input" if it was too much work.

gentle urchin
#

Thats what i was thinking aswell! So doing a custom manager sounded like it would be sufficient

maiden wadi
#

I'd personally probably handle that in a specialized widget. Widgets can negate any and all input to controllers, which means zero input in gameplay classes. You can pass the tutorial key to it and only do the callback if the widget registers that key on PreviewKeyDown. Else return Handled and don't allow input to anything else.

My character default runs but when I press the input to make it sprint it starts walking. Looking for any solutions

Widgets are also addable and removable easily. It's a very clean implementation without any extra work for gameplay stuff.

#

Not to mention it's already a widget, so you can display the key on screen.

Hey guys.. i'm trying to make my 4 characters controllers (1 client and 3 server players) to have individual colours. Currently the colour that displays is the first entry in the sequence set the colour to each individual controller? I don't think it's a replication issue as I previously had each player spawning with their own unique random colour (float based RGB variables). Any help much appreciated!

Its a bit weird naming on those pins imo

not obvious what they are

# faint pasture Several thousand per vehicle? You're gonna have a bad time making them actors, ...

Space ships. And yes, "I'm then looking at going through each of these actors and pulling the data from them and then turning them into instanced static meshes dynamically, adding in equivalents to each component (some of which will run code). " But yes, I am intending on having a system that will simplify the physics geometry. Especially since my expectation is that most of the geometry will be flat. Getting the thing to render at a reasonable rate is a good first step though.

Hi im trying to build an actor (a room) that contains other actors (doors / buttons) and some of them needs to reference each other, ive run into some problems. This makes them child actor components (and i can understand that they are pretty bad?) So what would the right procedure be for them to reference each other so the buttons can open the doors? I want to generate these rooms randomly at runtime and have all the "connections" work out. Maybe not possible with BPs?

gentle urchin
#

Are they placed in the same location relative to the door each time?

#

Letting the door spawn the button could be an option?

#

Or handle them through a common manager

fierce axle
#

the location and amount changes as well each time.

gentle urchin
#

Room spawns door?

#

And room spawns buttons

#

Thus could connect them, no?

fierce axle
#

yeah i guess if i can then place some points in the room blueprint that tells where to put them ?

gentle urchin
#

Yeah

fierce axle
#

hmm ill consider that. thanks!

#

but theres no way of "casting" or stuff like that?

gentle urchin
#

Not directly

#

Youd need a ref

#

could be collected with a mutlitrace/overlap check, or dirty old GetAllActorsOfClass

#

id let the door spawn the buttons tbh

#

and just input locations/transforms for where to spawn them

fierce axle
#

Alright - its gonna be a hassle, but i think i can make it work 😅

odd ember
#

you could also use subsystems that each room registers to and tells where to spawn doors, buttons etc.

#

and let the subsystem handle that

#

but that requires #cpp

gentle urchin
#

^ sounds like a superior solution

fierce axle
#

yeah

#

theres one major issue with the door spawning scenario if i want 2 rooms to share a door. that works now by both having the same door in their list, but if they both spawn it.. thats not gonna work.

gentle urchin
#

Yeah thats not gonna work

#

but

#

would both rooms needs to share it ?

#

or do you mean if a button is placed in each room, that belongs to a singular door ?

fierce axle
#

yeah they would both have to be able to affect it

gentle urchin
#

subsystem ftw!

#

which acts as a manager really 😄

#

then they can all interconnect if you want

fierce axle
#

ill research it!

Hey all, something that has been doing my head in, couldn't find anything by googling, but not sure if this is an "expected" behaviour. Basically I have an actor with a vector variable with editor widget enabled. Just for visualisation I'm binding a capsule to it via the construction script. The problem is, when the widget's location is changed, the pivot doesn't stay in the new location, but returns back to origin, which is super annoying. See gif to better show what I mean

Animation.gif
#

Any idea if this is a bug/setting that can be changed?

#

Because I can't imagine that this is how it should be 😂

odd ember
#

each room is a node, the edges would be doors, windows etc.

#

you could set that up inside a subsystem too

#

but now we're getting really technical

sacred current
#

Hi all, Why "Do Once" node can't be used inside a function?

fierce axle
#

@odd ember Ill try some more low tech stuff first and then see how deep i need to go with it 👍

#

and cheers!

odd ember
#

every time you invoke a function, it's essentially a new instance of that function

jaunty summit
odd ember
#

so a DoOnce would never do anything, since it would always be the first time you trigger it

jaunty summit
odd ember
#

scope can never carry over

jaunty summit
#

I mean it's a new instance you're right, but how then events are different from functions?

#

OnButtonClicked

odd ember
#

that's why they can't have return values

jaunty summit
#

I see, makes sense, thanks for the clarification!

odd ember
#

or rather, they are instanced as part of the event graph

#

which is essentially the object itself

odd ember
sacred current
#

good to know I thought the only differences were return and delay.

jaunty summit
odd ember
#

no just how blueprints are treated in the VM

jaunty summit
#

How would you see that

odd ember
#

in cpp kappa

jaunty summit
#

Blueprint nativization is just that

odd ember
#

well no, blueprint nativization is the attempt to turn blueprint nodes into more efficient code. but it's been deprecated

jaunty summit
#

Though it's not that readable

odd ember
#

the VM that runs the blueprint code instanciates everything

gentle urchin
#

Why is it so hard to make the c++ equivalent code readable really

#

the nativization part

odd ember
#

I think it's less about making it readable and more about attempting to circumvent the VM

gentle urchin
#

I guess it's not a focus to have it readable either

obtuse herald
#

Also latent stuff doesn't really exist in CPP like it does in BP

#

And making that conversation readable is probably not easy

odd ember
#

well it does, but it's much more of a faff to setup

#

below the hood it works in the same way

jaunty summit
icy dragon

#

BP Nativisation is like a crude reverse engineering tool

odd ember
#

a latent action is just an automatically bound delegate that gets called whenever some action has ended

obtuse herald
#

Yeah but that gets checked on tick afaik

odd ember
#

it just has a separate interface in BP

obtuse herald
#

I don't mean that

#

I just mean the conversation from delay node to cpp

Is probably hard to make readable

when a timer ticks at subtick time, it will update multiple times on the next tick

#

also why a delay of 0.0 executes on the next frame

#

(because it's the next tick)

gentle urchin
#

so there's an explicit check for 0.0 , else calculate execution(s) during next tick

odd ember
# gentle urchin so there's an explicit check for 0.0 , else calculate execution(s) during next t... 
void UKismetSystemLibrary::Delay(const UObject* WorldContextObject, float Duration, FLatentActionInfo LatentInfo )
{
    if (UWorld* World = GEngine->GetWorldFromContextObject(WorldContextObject, EGetWorldErrorMode::LogAndReturnNull))
    {
        FLatentActionManager& LatentActionManager = World->GetLatentActionManager();
        if (LatentActionManager.FindExistingAction<FDelayAction>(LatentInfo.CallbackTarget, LatentInfo.UUID) == NULL)
        {
            LatentActionManager.AddNewAction(LatentInfo.CallbackTarget, LatentInfo.UUID, new FDelayAction(Duration, LatentInfo));
        }
    }
}```
#

it's not a check, it's just the nature of how things work

#

things only update on tick

gentle urchin
#

Gotta go deeper than that to find the check

odd ember
#

but coroutine like behavior runs in the background regardless

gentle urchin
#

the Action hander would probably have it

#

anyway, not important at all

#

it works as it works^^

#

like you described

well if you can show the code feel free

Hey peeps, looking for some advice regarding the procedural mesh generator.

I am wanting to implement the formula:

r = sin(a * φ)^b + cos(c * φ)^d + sin(e * θ)^f + cos(g * θ)^h

to describe representations of spherical harmonics. I was able to get something similar working in Blender's Serpens system, but don't know if it's possible or how to achieve this in the procedural mesh generator.

Can you offer any advice on how to get started / what the basic setup will look like?

#

Is it possible to create a BP function that accepts an event delegate similar to Set Timer by Event ? Other than using CPP I mean

earnest tangle
#

Not really but also kind of yes

#

If your function has a delegate pin in one of the nodes it uses, you can drag from that pin into the function's start node, which should trigger it to generate a delegate parameter pin for the function

#

But you can't really do anything with it, other than pass it into a C++ based node which does something with it

Thanks!

when you close the inventory you call Hide event ?

I don't

#

the inventory open/close is build on the character, while the rest is built on the inventory UI graph

dusty rune
#

I made something similar and it worked

#

the added child is disappeared as soon as the parent are removed from view

unique cloud
#

so if you open the child and close the inventory without closing the child, re-open the inventory the child is not displaying?

#

I have no issue with the child removed from view when I close the inventory, its when I re-open the inventory, the child is still open by default and stuck there

dusty rune
#

ah sorry i thought you meant it stuck on screen when you close the inventory

unique cloud
#

Could be due to my bad english 😅

dusty rune
#

so you just call the hide event when you open the inventory then

#

it might get an error for the first time so put an if valid before removing from parent

#

or change it to Set visibility to hidden

unique cloud
#

instead of a custom event for hiding it, should I make a BPI to call it from the character?
