blueprint

[jovial steeple]

You typicly dont want to be using the mesh for collision (many times people littearly disable all collison on the actual mesh).

You would want to check against the capsole componet.

[frosty heron]

not really... you do want to use the mesh collision for an fps game for example

you do want to account for headshot, arm damage, etc when you actually hit the proper area

if you actually want to trace againts the body parts, then use mesh for the collision

otherwise you can just trace againts the capsule component

[jovial steeple]

Im not sure what the default collison settings are for the default capsole, but i beleive its a pawn object type?

[frosty heron]

like an RPG game where you don't care about hitting the head, you can just simplify the combat by hitting the capsule

[restive radish]

pawn type

with visibility channel set to ignore

[jovial steeple]

I really need to open unreal so I can tell you exactly what function to put D:

[restive radish]

well, it does work now

[jovial steeple]

Hard to remember the names ontop of my head

Well yes

If you want to just set the capsole compnets visility to true

That works to

[restive radish]

i did.

[frosty heron]

set it to overlap, not blocking

[jovial steeple]

Awesome!

[restive radish]

oh it doesn't work now

[frosty heron]

if you need to trace againts the mesh collision, e.g. looking to shoot a headshot, you will just have to make a new custom channel

[jovial steeple]

Oh yea thats right

Hit and overlap are two different things

You would need to be able to HIT for a linetrace

[restive radish]

i did make a new custom channel for explosion

[jovial steeple]

You may want to setup a new collision channel for this.

Then linetrace by that chennel!

And set the capsole collision to block that channel

[restive radish]

i have that setup already, but then i need every new wall or object to block this channel as well

so do i just make it default block?

[jovial steeple]

Yes, you can set up the default value for that channel to be block

You can even customize it to be block only for certian presets

I also see another potential bug

I dont see a point in using the find look at rotaion / foward vector formula to find the end point of your linetrace.

You can simply start at the center of the grenade, and end at the potentialy exploding actors location.

Currently, your linetraces are extending 450 units, past the exposion radius of 400

[restive radish]

i did do it , and then i added this forward vector section because i thought that the character is "escaping" the line trace by jumping

i will remove it

[jovial steeple]

Not as this would be causing a bug right now. But could be a bug in the future as you adjust values

[restive radish]

originally it was from grenade origin to player origin

[jovial steeple]

Awesome

[restive radish]

thank you for the help! @jovial steeple @frosty heron @dark drum

[jovial steeple]

I've seen this happen before when there is some massive invisible collider blocking the spawning area (Possibly some mesh with weird collision). Ive also seen it happen if you override some of the framework functions for FindPlayerStart and such incorrectly.

Most of the time its just some invisible collision though, and the game trys to adjust the players spawn point outside of it.

You may be able to check for that using the player collison debug draw mode.

It seems as if you have a suspicious water mesh all over your spawn room 🤔. Confirm it has no collision

[olive yarrow]

I.... Help, I didn't - how would I?

[narrow sentinel]

so I need some suggestions, I have this pod thing which player gets into when moving to and from the reactor however as it moves either one of two things are happening

there is a glitch in the movement code so can be times it may move back to where it thought it was but isn't, or the player isn't moving with it quick enough and as such the player is trying to catch up at same time it's roughly moving and causing the glitchy feeling

would it be advised I have the player sit before it moves to prevent any odd things happening ?

[west crescent]

I have been using the Asset Manager to load Primary Data Assets like this. However, this will load all assets of the given type and I have now come to the point where I would like to load only some assets of the given type. Maybe only from a certain folder. Is that possible?

I guess I could filter the Primary Asset Id List by asset name before loading the actual assets. That feels a bit like a workaround though

Or if I had to rephrase my question: How do you group/sort Primary Data Assets of the same type and load them by group instead of all assets?

[foggy arch]

HI everyone.
I'm new to UE, doing blueprint-only project, and currently don't even know what and how to google and where to look for an answer, thus I'm here

I'm currently implementing a 2D map for the game that has nodes (like a combat node, event node etc), and the player can interact with those nodes by clicking on them. The system every roguelike game have. All those nodes are Widgets. And I need to draw a path (line) between the nodes that are available to the player to show where they can "move" and which nodes are available.
And I don't understand how to find one node (widget) from another node without too much hustle.
Sure, I can create variables and manually assign "neighboring" nodes by hand, but that's just too much.
When the map was 3D, I just did box/capsule trace around the node to find surrounding nodes and draw a path, but how do I do this in 2D with widgets?..

[jovial steeple]

It seems that you are attempting to use front end user UI to manage a backend data system.

This is an example of how you would typically implement this:

• There is a backend NodeManager class. This is just data/code and is never seen by the player. This node manager stores data about each node, it has a function to retrieve nodes at certain cordinates, add nodes at cordinates, etc. It would store all this data in some sort of list of all nodes.
• There is a front end UI class. This is the visual node map the player will see. It makes calls to the NodeManager to find out which nodes to draw in which spots. This UI can always ask the node manager to find nodes closest to another node.

Also, the benifit of using this sort of seperation between the backend data, and the front end user display, is that you can change the user display to anything without actualy affecting the backend data.

Meaning the same backend data manager class could be used to power both a 3D map, like you previously had, and this new 2D map.

Devs often do things like this to speed up itteration time, for example if you decided to change your map to 2D all of a sudden.

[foggy arch]

I see
But how do I input nodes into the Manager? By hand? That's what I don't want to do
Regardless if it's backend or frontend, the question is how to operate it, how to find nearby nodes.
From what I can guess from your idea, I make something like a coordinate system where I can state the coordinates I want? But still, I'll need to input the nodes by hand first, which I really really don't want to do

[undone bluff]

if the nodes are placed on a canvas panel you can retrieve position

you can iterate over the other nodes and see which are in range

just subtract one position from the other

and see if the resulting vector is below a threshold

[foggy arch]

Oh, that's it!
I can just grab all nodes from the class, get a list, and iterate from the list to compare coordinates and see if they are in range!

[jovial steeple]

• You can either input new nodes into your manager by hand, or have a GenerateRandomNodesMap function call the AddNode function on your NodeManager a bunch to generate new nodes through code.
• There is not really a clear way to retrieve nearby nodes using the widget system alone. It depends on how exactly your widget is setup. Using a NodeManager with an actual retreive nearby nodes function would handle this.
• You could use a cordinate system in the node manager or anything else. It can be done in many ways.

[jovial steeple]

This is a hacky enough solution to work yes.

[undone bluff]

that's a lot of nothing

[thin panther]

It also sounds oddly GPT

[jovial steeple]

It would be a custom system made by him designed for his need. I dont know what he wants exactly its just an overview

[stray lark]

In case you're interested, I did end up replacing all my trace logic using CPP, which was equally slow.
I found out what the problem was. Turns out unreal's Paper2D turns every tile in a tilemap into its own box for collision, so my entire 100x100 map's ground is made up of 10,000 separate box colliders. (Whyyyy doesn't it combine???) It's normally not a problem, but I guess the fps issues surface when trying to trace against all those colliders. Turning off the tilemap's built-in collision and replacing it with a single regular plane fixed the entire issue. I can run 400 line traces per tick without any slowdown now.

[remote cairn]

Where should i start learning blueprints

Bro anyone there

Help me

[thin panther]

Bruh be patient

A whole two minutes of waiting

[remote cairn]

Ok

[atomic salmon]

@remote cairngo the the Learn Catalog and filter on Beginner or search for Blueprints: https://academy.unrealengine.com/totara/catalog/index.php

This may be a good one to start with:

[remote cairn]

Ok thank you

It means a lot

[atomic salmon]

You can also check out here: https://dev.epicgames.com/community/unreal-engine/learning even if at the moment I am getting a 400 error

It may just be an issue on my side though

[woven lark]

pls help how do i fire it only one time? do once node doesnt work

wait nvm i will move logic to the eventbeginoverlap and use hit only to update hit direction and location

[narrow sentinel]

so i'm having an issue where if I attach my player character to a scene component within my BP actor and the have my BP actor move my player gradually glitches to outside the NP actor and being pushed off into the void

for context the BP Actor

the longish box in middle is the seat component that player can interact with where the following code is ran

Thats whats happening

also might want to turn volume down as there sound with the vid that may be little load

so from what I can tell it's like the actor is lagging behind so the component players attached to is moving but in that tick the actor hasn't moved yet so techinally it's not there with player ending up on the outside of it

anyone able to help me refine this to see what I've got incorrect

please

[candid blade]

Hey all, I’d love some suggestions on something I’ve come across for a board game I’m working on. Ive been trying to implement rolling dice with impulse, full physics. The issue is that it doesn’t replicate accurately on other clients which means the results are always different than on the server-side. Besides a pre-determined approach where I would simply fake a dice roll with a timeline and some variable that has a result stored in it already, is it possible to get that physical aspect to replicate properly across all clients?

[narrow sentinel]

Anyone able to help me with my issue here please 😦

not sure whats going on like but

[mellow pike]

why would this be a problem ?

[dawn gazelle]

One is a component, the other is the actual mesh.

[prisma iron]

i have a function to grab an object and now i want to that i can move the grabbed object back and forth with mousewheel up and down, can someone help me with that?

[mellow pike]

NVM I see it

[turbid arch]

Quick question, is there anyway to check with blueprint nodes if I'm simulating game or in regular play? Or is that only possible in cpp

[plucky dome]

does anyone know why the top line of text isnt right-justified? is there a way to achieve this with richtext?

[sick sky]

check text justification

by default its left

[plucky dome]

whoops. thank you

[lunar sleet]

Nice. I didn’t know you were doing Paper2D or that it does that to the map but good to know

[languid hemlock]

They both work properly, but i wonder are these same things?

Debugging says resolver node is a "pure cast"

[dawn gazelle]

Kind of.
This will work only because you're calling the loading of the asset first. If you didn't load it first, then it would return none and cause an error when attempting to set the mesh. That said, casting to Static Mesh isn't the worst thing in the world.

[languid hemlock]

Got it, so result is always same if i use it on "Completed" output

Because it will return valid object if its completed ig

[narrow sentinel]

Anyone know why when I do this code it seems to fail, it seems like the character ends up grtting move further then the actual component it's attached to it moving leading to player being pushed outside vehicle and falling through the void

[dawn gazelle]

It should yea.

[languid hemlock]

Thankss

[dawn gazelle]

Your snap settinsg should probably be set to keep relative rather than snap to target.

or keep world

[narrow sentinel]

so if I do keep relative my player ends up way underneath in the void

[narrow sentinel]

wouldn't keep world mean it won't move with the component it's attached to ?

[dawn gazelle]

No. It defines how the actor is moved when attaching. "Snap to target" means to move the actor to the location of the actor it's being attached to for example.

[narrow sentinel]

i'll give keep world a try see what happens

[proud mauve]

Thanks, that works. My videos are all 3840x2160. How can translate that resolution to the plane that plays the video?

[tight pollen]

hi, why Slot Group doesn't work in Linked Anim Graph?

[frosty heron]

They do

Can you click on your anim graph and show the settings?

[frosty heron]

You probably want to slice them. Divide the task into multiple frames instead checking all of the 10k collisions in a single frame.

Keep the func in cpp if you are going to loop that much, at least you don't pay for the bp overhead.

[flat coral]

Is there a way to get all actors that have a certain controller class? Working on stealth shit, basically need the list of everything in the level with a brain

[unique bone]

you know what i never see explained in any introductory videos on unreal? references/deleting/force deleting assets.
It kinda seems nonsensical. I have the starter content for first and third person templates loaded for example as a fun little task, going through all their blueprints and figuring out how they work/recreating my own versions of them. but when i go to delete the first person/third person folders after, the only option is forcedeleting due to a reference i apparently have. whatever that is.
and i go through all my blueprints and go box by box looking for any mention of a variable or input mapping or function defined in the third person blueprint and find nothing.

[thin panther]

References aren't always in a blueprint, or in the level.
If you find those references are gone after an editor restart, it just means you had them loaded into memory by some mechanism or another, not that it's necessarily going to mess things up.

Fortunately, if you use source control, as you should, permanent issues are hard to come by, you can always revert if you keep committing and pushing things

[unique bone]

i'd have to know what references actually are, along with what you mean by references being gone, or source control to get what you're telling me

i don't have any error saying references are gone. I just can't delete something in the content browser that isn't in use in any way as far as i can see

[thin panther]

Yes. A reference refers to the thing being loaded in memory. All it can mean is "Yeah, it isn't in any blueprints, but we still have the asset somewhere in memory, so here's the warning"

If you find you don't get the popup after an editor restart, that's what it will have been.

Source control is a way of keeping all the versions of your files on the project. If you do something bad and it messes something up, you can just revert back to a stable point. Think of it like time travel.

[unique bone]

ah ok i see

whatever memory constitutes, you'd think it'd be "what's actually being used in the game"

so for example-

yknow it's weird. maybe it's just because google can't find a damn thing these days, but any time i look up p much any proper noun from UE - like "memory" or "referencing". "memory reference", etc all i get is incredibly dense, highly technical jargon posts that feels like trying to read an untranslated foreign language by brute force and guesswork. you'd think there'd be exponentially more questions asked at an entry level of knowledge before people fall off and the number of people sticking with the engine winnow down

[thin panther]

It is in a way. Memory constitutes the things loaded into your RAM.
These assets are in RAM, despite them not necessarily being in the level or a blueprint.

[unique bone]

you mean at the time of using the editor or at the time of running the executable were you to make one?

[thin panther]

To be honest, it's because these are generally pretty technical subjects.
The engine as a whole is targetted for AAA so a lot of resources and documentation assume the baseline knowledge. It sucks, but it's the reality in a lot of cases

[thin panther]

At the time of the editor

It doesn't know what will be loaded in the packaged game, it only knows what references exist now

[unique bone]

so in other words when it simulates the game, that simulation is asking for x file to be present

[thin panther]

You fall into a sucky category for this engine a lot of times.
Tutorials that cover fundamentals well don't tend to be algorithm friendly so are hard to find. Tutorials that skip needed knowledge and charge in with flashy content do better and push to the front.

A lot of personal blogs aren't SEO friendly so don't appear on search results, and the documentation is aimed a lot more to it's AAA clients

[unique bone]

it's kind of a sliding scale between dense AAA jargon and garnering a bad reputation from being "too accessible" and having asset stores that are "too easy" as if that's a bad thing. like unity

[unique bone]

ig that makes sense that people working in those projects would be working with them daily and asking way way more questions online.

[thin panther]

Again, not quite.

It just means that at some point, of the editor being open, this asset was loaded into your RAM. for convenience with assets, it doesn't unload them so you get a nice smooth experience without hitches.
If those warnings disappear after a restart, you can confirm that all references have been properly removed and the asset is safe to delete. If they don't disappear, look around again or restart the PC

[unique bone]

ahhhh ok. i see.

thank you that clears it up very well

am i on the right track then thinking it'd be something similar to a function/variable/input etc

(there's prob more i'm just not acquainted with yet)

[thin panther]

No worries!
Again, worth a look into source control. It's your safety net. There's a guide in the pins of #ue5-general

It's useful if you ever make a mistake that does royally screw something up, you'll always have a restore point provided you keep committing and pushing changes.

[thin panther]

How do you mean?

[unique bone]

as in that's the kind of thing that'd make a persistent reference between restarts

[unique bone]

i've been operating on skyrim modding mentality of testing every thing i change before i save it lol. i probably should get on that

[thin panther]

It shouldn't make a persistent reference. Once the program has exited, your OS and the engine should clear up the space in RAM that it used, thus getting rid of the asset from memory.
If the error persists between editor sessions it means it is still in use somewhere by some other asset, or it's an odd transient error that a PC restart would fix.

[unique bone]

that's more or less how i'm imagining it.

[thin panther]

It could also mean it has a redirector living somewhere potentially that hasn't been freed up, so try fixing up redirectors in the folder and if you're extra sure, just hit the force delete. It shouldn't do anything bad, but it can, and that's why we have source control.

[unique bone]

gotcha.

this has been very helpful

[thin panther]

A redirector if you're unfamiliar is a special type of asset that gets made when you move something, it essentially lives at the old location, and tells the engine the new location of the asset. Its a stupid system and I hate it, and you won't be used to it from other engines, because things like unity just use things like .META files

[unique bone]

looks like you were right abt restarting the pc. that seems to have wiped it from memory. i guess i did get everything that was being referenced

[thin panther]

yay!

[unique bone]

i'll add that to my personal study doc

[thin panther]

an editor restart should be enough in most cases, but the editor can be a little funky sometimes and a pc restart is needed 😆

[unique bone]

now to do the same with the weird levels it asked me to save when a previous version of ue5 made you save a weird level file when using save-all

those unfortunately still get referenced in memory🙄

totally outside the scope of this q&a tho

[woeful yoke]

I want to deactivate the niagara component Door Shield, for some reasons I am able to activate it with this technique, but it is not getting deactivated when active. Is there something I am missing with niagara deactivation?

[lunar sleet]

Are you certain your code is reaching that point? Did you use breakpoints?

[woeful yoke]

yes, the code is reaching there, I used print string, I think it is due to Inactive Response of Niagara System State, selecting Kill solved it just now.

[obsidian coral]

is their a way to add a conditional check for if an actor in a map should be created? I want to give maps a world state, and only load certain actors depending on the player's world state for that zone. I know in beginplay i could do a check on the actor and just destroy itself if it's not part of the current world state, but that feels a bit inefficient, i was wondering if their might have be a better way to go about it?

[woeful yoke]

Btw, I did find that Blueprint Communication tutorial, it looks really loaded with information even though it's pretty old. Thanks a lot for the suggestions! Being new to blueprint, this helped me a lot!

[lunar sleet]

Yeah, Niagara’s got all sorts of finicky things 😅

[lunar sleet]

I mean you could do the opposite and create it if needed, rather than destroy it if not needed

[obsidian coral]

well the problem with that is then i can't just place the actor in the level right?

hmm, i could technically have a level data asset which has a list of actors to track/spawn on map load, then i could mark those actors as editor only actors, so when i package the game the level data would be aware of what to spawn in/where for the map.

[lunar sleet]

I prefer spawning over placing anyways but that’s just me 😁

[obsidian coral]

hmm i see, well this idea might work well enough for what i want, thanks.

[lunar sleet]

it's a shame that you can easily copy functions and components from one bp to another, but can't select all variables and paste them in the same way 😦

[idle rivet]

anyone has any idea how i can set the graph on a new PCG graph instance that i just created on disk? i cant seem to find any node that works, i tried casting to all sorts of PCG objects but nothing seems to work yet

[spark steppe]

imho the best thing they could do would be copy the variable scope when you copy a function and ask you to create the missing variables in the same scope

[lunar sleet]

right? It already prompts you to create missing functions, why not vars

[lunar sleet]

I'd ask the #pcg-framework crew

[idle rivet]

good idea

[lunar sleet]

I have to go look at each greyed out var and right click Create Variable and hope that I got them all before I hit Compile and the engine yells at me 50x times 😄

[tiny ember]

Hello
I am attempting to do the following:
Object collides with an actor with a collision box
Object is attached to the actor
A copy of the actor nearby spawns a copy of the object, and attaches it to itself
Then the copy object matches location to the original
But when I attempt to do it it spawns in the centre of the copy, and I cannot get it to move to the correct relative position.
Is there a math issue here, or is there an easier way to do this?

[lunar sleet]

Sockets?

[keen copper]

Why can't I trigger this damn thing? Either I get an error, when I don't get an error, the system doesn't work.
I tried to do it with a flat reference but it didn't work, so I tried with the interface and it still doesn't work.
Basically what I'm trying to do is : Make a weapon blueprint that will parent the others and just trigger it without adding code to my character.

[lunar sleet]

First you need to understand what the error is telling you. Then you need to learn how to debug your code. Then you'll be able to fix the code on your own 🙂

but just to save you sometime, that error means your AS BP Weapon Base is None (nullptr), so you are not setting it properly at the time it is being accessed. Or it's not set yet, in which case you need to have an isValid (?) check to mask the symptom

as for when it doesn't error out but still does not work, you'll need to use breakpoints to find out where the logic stops. You can't follow the code through an interface call though, so you'll need to put it on the interface event or on the message

[tiny ember]

I need it to work with multiple objects with physics,, so no unfortunately

[lunar sleet]

because...they're not SKMs or why

[tiny ember]

they are actors, and I need the object to enter the field, create a copy, then delete it when it leaves, and have as many do this as I want

[tacit bloom]

Hey, can someone help me solve this problem?. My character just spawns in the middle of nowhere

[lunar sleet]

what is this proxyInterior

[tiny ember]

its the copy of the actor: A copy of the actor nearby spawns a copy of the object, and attaches it to itself

[lunar sleet]

I could be blind but I don't see anywhere in your screenshot where you are setting that variable

[tiny ember]

Its set elsewhere

in begin play

just know its the copy of the object with the box collision

it has to be spawned on runtime, so its set in beginplay

[lunar sleet]

in my short xp with attach actor to actor, it'll attach to its center unless you give a socket. You can try attach actor to component with an arrow component or such maybe.

[tiny ember]

I know its setting centre, im fine with that

in the same frame I try to set it to the correct position

[lunar sleet]

you can't do that, it's attached.

[lunar sleet]

it is attached.

[thin panther]

Seems you have one already in the world set to auto possess

[tiny ember]

thats why im trying to set relative

spawn at 0, then force to the correct position before physics take effect

[lunar sleet]

Have you tried setting the xform manually and maybe checking what comes through

[tiny ember]

relative does not seem to fire tho

xform?

[lunar sleet]

Doesn't break on breakpoint?

[lunar sleet]

transform

[tiny ember]

interesting the breakpoint fired before collsion somehow

there we go now its fired properly

[tiny ember]

I ran the breakpoint and the spawned copy is not visible when it ran

does the spawn actor have a delay?

[lunar sleet]

depends how heavy it is, but usually no

[tiny ember]

bottom is the copy

[lunar sleet]

why is the set relative disconnected now?

[tiny ember]

I was testing something

[tacit bloom]

how?, i didn't understood

[thin panther]

You can place your character manually in the world. Make sure you don't have one.

[tiny ember]

I was just testing some different relative math, it was wrong, but its back now

[lunar sleet]

so you're back to visible but not being able to move it?

[tiny ember]

no I just moved to next frame, as you can see the nodes are no longer active, its like it waited a frame to spawn for some reason

[thin panther]

Where are you appearing in relation to the rest of the map?

[keen copper]

No, there is a fundamental problem here that I cannot solve. I opened a new blueprint, I tried both normal cast and interface, I can't even trigger a simple print string with my character. I don't remember experiencing something like this before, where am I making a logic mistake?

[tiny ember]

run a test off the cast node, it could be failing

[thin panther]

Yes, the issue here is your knowledge of references.

The owner of your RogueBase is probably not a NewBlueprint, thus you cannot cast it to it

A cast is a type check.

In this, you're asking if the owner of RogueBase, which is probably nothing, is a NewBlueprint

[lunar sleet]

wdym "no", no what?

but also if you're having weird issues, restart Unreal for sanity check

[violet spoke]

How to quickly drag drop nodes in between others?

[tiny ember]

?

oh with execution pins?

[violet spoke]

yes

[tiny ember]

ususally I just drag off when creating it

[violet spoke]

A - > B
you drag and it auto connects
A -> C -> B

so just with menu?

[lunar sleet]

yes

[tiny ember]

ye

I dont think theres an automated way to do it with existing nodes*, I havent found one at least

[lunar sleet]

there isn't

that's the closest to automatic you'll get

[violet spoke]

why would you want easy node connection in node framework

lol

[tiny ember]

its probably so you dont create a mess by accident

[lunar sleet]

eh, bigger fish to fry

[lunar sleet]

that too

[tiny ember]

the nodes are huge, so they might overlap multiple lines

eg sequence

[violet spoke]

mouse is small, just add shift modifier :<

[keen copper]

Can you simply tell me, how I can trigger an event in another blueprint with my Character?

[violet spoke]

interfaces or event dispatchers

[thin panther]

You need to get a reference to the blueprint

[tiny ember]

it needs to be cast correctly, otherwise it has no idea what its looking for

[thin panther]

Then you can call a function on it

casting isn't looking for anything

[tacit bloom]

from here

[tiny ember]

eg looking for type sorry bad wording

[thin panther]

casting is checking to see if something is the correct type, and return a converted reference if it is

[tiny ember]

he has some sort of reference there but its failing

[tiny ember]

is that 0,0,0?

[thin panther]

What is that volume you appear to be spawning in? The only thing I can think is that the engine thinks you are "inside" something and it's trying to move you out

[tiny ember]

^

[tacit bloom]

i''m 99% sure

[thin panther]

Turn on your collision view

See if you're trying to spawn in a collider or something

It's an odd one

[tiny ember]

pause quickly, then press F8 and select your character, it will give you the coords

also check what your character is

also, check if you have multiple game starts

could be set to the wrong index

[high grove]

Why doesnt this work??

[thin panther]

...it does?

Define doesn't work

[faint pasture]

Because by the time the delay has happened, the component might have started overlapping something else

other actor is the THING TO TRIGGER THIS SPECIFIC OVERLAP

[high grove]

It doesnt apply the damage

[tiny ember]

it should still fire tho, it has the references

[faint pasture]

there's no guarantee that OtherActor will still be the same thing by the time that delay finishes

[thin panther]

Also make sure you're actually receiving damage somewhere

[high grove]

Yeah I am

[thin panther]

I've seen people before think that health and damage works automatically :P

[high grove]

Ok

[thin panther]

Then yeah, what Adriel said

[faint pasture]

This is exactly what that code will do:
Something Overlapped!
wait 0.6 seconds
Damage the last thing to have overlapped.

you could overlap 30 things in one frame

[tiny ember]

maybe store it temporarily

[faint pasture]

get it to work without the delay first

[tiny ember]

altho nvm because it would get overidden

[thin panther]

There's a better collision viewer. click where it says "perspective".

Should show everything in solid colour blocks where colliders are

[high grove]

Yeah it works with out the delay

It just doesnt when I add the delay

[faint pasture]

then its exactly the problem i laid out

[tiny ember]

youd need to stand in the field for 0.6 seconds to get damaged 😛

[thin panther]

could always wait on receiving the damage :P

[faint pasture]

What are you intending it to behave like?

[tiny ember]

maybe set up a timed event

[faint pasture]

that you get damaged 0.6s after entering the area, no matter what? Or that you have 0.6 of grace period before it hits you

[high grove]

Grace before it hits

[faint pasture]

You need more logic than this then. First off, you want to filter out all the overlaps you don't care about.
You can do that by casting or refining the collision settings or various other ways.

[tiny ember]

one quick thing you could do is just move your player start somewhere safe and test that

like on its own out of the map with a platform

just make sure its not collisions

[tacit bloom]

i've have only one player start in all my project

[faint pasture]

Do you care about hitting anything besides the player's pawn?

[thin panther]

sorry, said the wrong thing 😆
Meant where it said lit

Keep the perspective view

[tiny ember]

its just in case, sometimes Ive done that and its messed up a few things

[thin panther]

My concern is it's adjusting you to the bottom of that green collider there

[tacit bloom]

i've aleready done that, still not working

[tiny ember]

ok thats weird

[thin panther]

If it isn't, I haven't a clue

[tiny ember]

maybe delete the start and create the character manually

[tacit bloom]

the thing comes like this. I've done all this tutorial says https://www.youtube.com/watch?v=yea9YP3lPcw and it didn't worked, so I revert all that settings as the default settings of unreal engine, but after applying that tutorial stuff my character just spawns there

[tacit bloom]

how can i do that?

[high grove]

Yeah I just wanna hit the player

[tiny ember]

delete the game start and just place the character in the world

with auto possess

[faint pasture]

Looping or 1 time per entry?

[high grove]

One time per entry

[faint pasture]

if im standing in area do i get hit once or once per x seconds

[high grove]

Just once @faint pasture

[tacit bloom]

should I follow this tutorial?
https://www.youtube.com/watch?v=dgkQGUeWKSA

[tiny ember]

all pawns come with autopossess

[unique bone]

how would you efficiently make a tap sprint? ie sprint until you move backwards in first person or until your movement abruptly stops/you stop touching analog/wasd

as in- how do i either trigger that condition to run my simple Terminate Sprint function without continually looping and checking for the stop conditions, or only check while my character is sprinting

[faint pasture]

Easiest way I can think of

BeginOverlap -> check if it's players pawn (cast, equality, however) -> set timer
EndOverlap -> check if it's players pawn (cast, equality, however) -> clear timer
Timer -> dmg the players pawn or all overlapping actors or whatever

[faint pasture]

Multiplayer or singleplayer?

[unique bone]

single but i'd happily learn both lol

[faint pasture]

I mean in multiplayer you don't make a sprint in BP at all

[tiny ember]

multiplayer is a bit special 😄

[tacit bloom]

that worked

[unique bone]

more of a come back when you know c++ kind of thing?

[tacit bloom]

but i can only play with the current camera location

[faint pasture]

multiplayer movement is a big topic

[unique bone]

ic

[faint pasture]

but ignoring that, assuming sprinting is just setting max speed on CMC

you gotta check

[unique bone]

cmc?

[high grove]

cant I just make it so that it only overlaps with pawns? in the collision settings or something?

[unique bone]

oh, my question was how to efficiently end the sprint

[faint pasture]

something somewhere gotta do some checking. If you don't alaready have events for releasing input or stopping or slowing (from something else checking), then you gotta check.

[tacit bloom]

although before i spawned in 0,0,0 with both views

[tiny ember]

that might mean there is another pawn somewhere in your world also trying to possess, and placing it manually overrode it

oh ok

[faint pasture]

Yes, but if you have AI then they are pawns too

it all depends on what you actually want the rules to be

[tacit bloom]

ok, that helps a lot. How can i locate and delete this pawn in order to spawn my character from the player start?

[tiny ember]

I dont know if theres a quick way

but if you mentioned you still spawn at 0,0,0

it might not be

[faint pasture]

You're already handling inputs on tick anyway, it's dirt cheap to just check if input is still in the forward direction and velocity is still above some value

[tiny ember]

hmm maybe make a temporary new pawn and possess that

[unique bone]

blame minecraft java brain for assuming like 6 things on tick will ruin the game lol

[tacit bloom]

ok, i'll try that

is there a way to only associate my chacter with the player start?

[tiny ember]

if you still spawn as your third person character, then something is overriding it

[tiny ember]

think thats set in gamemode

[faint pasture]

Whether or not the character should end sprint is fundamentally a "check it each frame" problem. Something, somewhere, has to tick and check.

[tacit bloom]

ok, thank you very much. I'll manage to delete the pawn that is overriding my character. Now i have a clear view of what problem i have and how to solve it, so thanks

[unique bone]

good to know. is there fundamentally no way to run something on tick but only if bool is true?

i mean i guess it sounds like one of those fundamental issues

[tacit bloom]

and thanks for you too @thin panther

[faint pasture]

tick -> branch

I mean you're ticking anyway

[unique bone]

gotcha

fair enough

[thin panther]

No worries! Apologies I couldn't be more help!

[faint pasture]

Now if sprinting was just dependent on the button then it'd be a no brainer, but it's dependend on some derived state (velocity, input direction), that can change over time

[lunar sleet]

@dark drum @frosty heron for future ref, the missing SKM in Standalone was due to some weird char corruption. The fix was reparenting to Pawn and back to Character (after many other failed attempts at a solution)

[high grove]

I got it working, thanks so much for the help @faint pasture

[thin panther]

glad you managed to fix it

[tacit bloom]

don't worry, youtube, chat gpt, and unreal engine's foroum either

[tacit bloom]

if i can't find the pawn that its overriding my charcter i'll have to start a new project

https://tenor.com/view/shoot-me-shoot-me-now-king-of-the-hill-hank-hill-water-gif-16249718

[true ocean]

Hey is there a better way to use "local variables" in events? Since impure function calls cache the values of their output pins, I'm using them to fill that role

[lunar sleet]

You mean inside the functions ? Cause you can just GET the input anywhere in that graph

[true ocean]

no i needed to save the starting location so it can be used throughout the timeline, which i would have used a local var for in a function, but this has to be an event

[honest arch]

hey guys, when im holding down right click to pan my graph, sometimes when i release the mouse button it opens the node picker panel, and its kind of annoying when im trying to navigate.
anyone know how to stop that from happening on accident?

[unique bone]

any idea why the part in pink can't be used to detect if the character is stationary/moving backwards?

more specifically it can't detect motionlessness

it treats either motionless or backwards as correct. whichever fired last. so if you tap s and let the char idle you'll get a correct printing of the stationary/backwards string nonstop, but the exact same can be said for w, s, d

[odd kiln]

Hi all

Is there a way to use a single "On Component Begin Overlap" node for multiple Collisions in the same Blueprint ?

I have 10 Box Collisions on my Blueprint Actor and I'm wondering if I need to call "On Component Begin Overlap" for each or I can use something to use only one node ?

I guess I found it, sorry !

[unique bone]

so i'm getting weirdly fixated on this weird little quirk that evidently just doesn't sit right with my brain

i'm sure when i do see it it'll seem really stupid but right now my dissolving brain just doesn't comprehend how this doesn't print string number 2 when i move backwards with s.

it's not like it's a third person problem exclusively. i'm using a cheap first person button for this where i use controller rotation yaw and stop orienting rotation to movement when the player enters first person so i'd assume that messes with output of the forward vectors in my previous image

and even then it detects the greater-than and not-equals in the middle of the second pic as identical for purposes of checking if the player is going backwards in first person and should ostensibly have a negative y value

is that velocity relative to the coords of the level instead of the player char vector? do i need something other than get velocity?

[lunar sleet]

There’s a get/set velocity in local space

[unique bone]

got an exact name? doesn't wanna come up for me

in google either because google

[lunar sleet]

That was supposed to be the exact name

[unique bone]

damn

[lunar sleet]

Ik I’ve had to use set velocity in local space iirc

But also why do the velocity check?

[unique bone]

it's for detecting backward movement as an immediate way to end sprinting

[lunar sleet]

Oh hang on

You’re doing equals or not equals zero on a float

You can’t do that

It’ll never be exactly 0

Use near equals

[unique bone]

oh weird. i just sorta assumed there'd be a point where 0.0000 whatever would just snap into 0 for some reson

[lunar sleet]

Nope

[unique bone]

wait but the part acting up is the greater than

in fact that equals actually seems to be working

even in first person if i stay still, move left or right with no other inputs (not analog), then stop moving, it correctly prints not moving

[honest arch]

aha having this on is what made that issue

[olive yarrow]

@thin panther i diiiid iiiiitttt

[thin panther]

congrats!

[unique bone]

can anyone tell me why this is behaving like the selected absolute value is being ignored?

this works with the exception that velocity x is returning a negative value when going left despite the ABS

how is that even possible

[hardy merlin]

Do components have constructor scripts?

[unique bone]

i don't even understand constructor scripts so i'm leaving them alone for now

[thin panther]

no

[unique bone]

oh ok so it's the velocity. it's using world coordinates not local space

i still can't seem to get local space velocity

[thin panther]

construction script is just something that runs slightly before the actor appears in the world. It's more of an editor time convenience and is stripped out of shipping iirc.
Say you wanted to randomize a material, or construct a spline road. Construction script is your friend

[unique bone]

oh ok

but yeah this whole thing is just supposed to return no if staying still or going backwards and yes if going forward or to the side 😭

[hardy merlin]

I have a component that spawns and attaches a weapon actor amon begin play. I want to be able to have the weapon he present at edit time. How can I do that?

[thin panther]

the short answer is that you don't

you could use a child actor component for a visual placeholder only, but don't use it for your actual weapon logic

[unique bone]

i'm losing my mind
how do i get my local velocity

[lunar sleet]

Weird I guess you can SET but not GET it in local space ?

[unique bone]

i guess but that set was only for projectile movement evidently

[hardy merlin]

A preview is a good idea. Would the placeholder just get destroyed on begin play?

[thin panther]

not automatically. You could hide it in play.
Just remember to strip it out

[lunar sleet]

Oh, that makes sense. I guess I was dealing with projectiles 😅

[unique bone]

why is this incredibly basic simple thing off limits completely 🥹

[lunar sleet]

Maybe you’re approaching this the wrong way

[unique bone]

how do we have local coordinate systems on actors and we CANNOT get any info from them

why are they there

[lunar sleet]

Why are you doing this again? In simplest terms

[unique bone]

return 1 if going forward left or right
return 0 if going backwards or staying still

that's the whole thing

[lunar sleet]

Break your IA into 2

W/S and A/D

That will at least narrow it down to W or S only

[unique bone]

i guess??? but i'll still need to know my velocity relative to my rotation like a thousand more times with the things i have lined up in my queue to learn to do

[lunar sleet]

Then, if using negate when pressing W or S you should see 1 or -1, 0 for idle

Velocity shouldn’t be relevant unless your character drifts after releasing input

Is this a car or something ?

[unique bone]

it's an adaptive first or third person character

[lunar sleet]

So not a car

So it stops moving forward if you stop pressing W right?

[unique bone]

yea

[lunar sleet]

Good, so do what I said

Velocity is not a factor

[unique bone]

wait that still doesn't fix it because this is something i need to detect on tick, not on tick but ONLY if pressing an IA button
sideways movement should still keep the sprint/dash active even if you've let go of W and vice versa

so yeah

maybe i'm asking the wrong question and nobody knows wtf i'm asking because it's such a basic thing idk how a game could even be made without knowing it.

How do you normally detect your character is going forward, left, right, diagonal, etc from their perspective

[lunar sleet]

I don’t understand, you still want the char to run after releasing input?

[unique bone]

yes

[lunar sleet]

#blueprint message

You said the opposite here

[unique bone]

as in you can let go of shift, not w

[thorny kestrel]

you can put the logic after you press the IA

[unique bone]

like update a variable after completed/canceled?

yeah i guess that could work in a roundabout way

[thorny kestrel]

yes

[gaunt stirrup]

does fab not automatically add the shit into your project?\

[lunar sleet]

#fab but I don't think so

[faint pasture]

unrotate global velocity by your rotation

[pulsar osprey]

dot products and cross products of vectors

[spark steppe]

i think the plugin does

[idle vigil]

im unable interact with the 3d widget even though the debug sphere of the widget interaction component is on top of the button

are there any common gotchas that anyone know of?

im calling these nodes on the widget interact component. the print node also fires when i left click

[stray lark]

I wasn't trying to check against 10k box colliders. I just didn't know that the paper2d tilemaps split them up into 10k of them.

I ended up not trusting paper2d to create colliders and went from 10k colliders to like 30 on a small map like that. I can run like 500 line traces per tick without going under 600 fps on standalone. Lesson learned about tilemaps.

[frosty heron]

Sure I'm just saying if you do have a gigantic task, split them up between frames.

[stray lark]

Well this was for UI so I needed it to be responsive on the tick. Not much I could have done there.

And I WAS wondering why starting PIE took like 10 seconds, I think it was rebuilding collisions every time

One thing I did consider was batching these line traces in CPP, looking at the code for AI perception, but that's for a different channel

[spring lodge]

so i have this issue where i want to use the sword locomotion state machine only when i have my sword equipped and use the other animations when i dont have it equipped, i made a bool that updates when i have it equipped or not, i thought i would just put a branch node but didnt know it doesnt exist in animations, can anyone help how i can do this

[dark drum]

You're looking for the blend by bool node.

[spring lodge]

also if i have a bool in bp_thirdperson i can get it into animation bp by having the same name right

[dark drum]

No, that's not how vars work. You would need to get the value from the third person character and store the value to be used in the animBP. In a lot of cases, this would have to be done each time the animBP is updated.

[split salmon]

The static meshes has collision and camera is all setup, event so, overlaps with the static mesh. What am i missing here?

[frosty heron]

Increase the probe size, but even so it's not a really a fix

That is because you need more elaborate formula to find the best placement for the camera

Spring arm will never look good

[split salmon]

tyty

[frosty heron]

@split salmon 1st video is using spring arm.
2nd Video , there is calculation done every frame, to check how much the camera penetrate something, then offset it for the best placement. Final location is defined by a curve. (The code is from Lyra sample game)

I can see you are in C++ server, if you want better camera system, just steal lyra's code

you can look at penetration feeler and camera manager

[split salmon]

Neat Stuff! Thanks!

[young meteor]

How do I go about handling Save Game files once I have my game uploaded to Steam, and then upload a new version of the game?

I mean if the Save file contains variables and such that may have changed in the new version?
Could be stuff like:
Enum entries no longer existing
Stats (floats) now rolling in a different range to balance game.

[frosty heron]

well if the enum entries no longer exist and none of your code use the enum anymore, you technically shouldn't run into problem?

You do have to keep in mind the difference between the old and the new save file.
There are times where some things gone wrong for different save files for me.

30% of my dev time is spent on bug fixing and patches. Some patch does a check for save files that get broken from previous patch

[young meteor]

I have a skill tree with skill nodes set up based on Enums with a float right now.
Say I no longer want that node in the skill tree to be available. But the player chose it before the update.
Actually it is linked with a "Name" now that I think about it.

[frosty heron]

use gameplay tags over name

anyway the .sav file can be though of as a JSON object or a text file

how you read and write is entirely up to you

[young meteor]

my names are just numbers basically.

0, 1, 2 and so forth.

Don't understand the JSON object part.

[frosty heron]

I don't know the context but that's why enum exist. Basically a number but with descriptive name.

but in almost all casses, gameplay tag is just simply better

no typo and you get the description of the state

[young meteor]

I will keep the gameplay tag part in mind and use it whenever applicable.

[frosty heron]

this is more or less what youe save file look like if it's readable

[young meteor]

okay. So "0" would be the slot?
And the rest is pretty much just variables?

[frosty heron]

@young meteor Saving is just storing data to a file. You can play around with modifying save file and updating your game.
It's hard to explain but you will understand how to address this more when you have testers. I've released my game for free on itch.io, the countless bug reports I get, I needed their .sav file to debug and make patch.

[idle vigil]

after hours of testing i was able to narrow down to issue a bit more: widget interaction works when there is only one player but when i increase the number of players to two it doesn't work anymore as soon as the second player spawns in. What kind of setting could be causing this behaviour?

[dark drum]

The data saved would be exactly the same, the question is whether or not you use the data in the same way.

I had an instance where I had to regenerate all the GUID's used for all pre placed world items. This meant all saved data retaining to world items broke.

[young meteor]

Okay, thank you.

My biggest fear is I'm considering uploading the game with a Demo on steam.

Right now I have some Structs as part of the Save game function.
If I change it later and they run into bugs that is just a hassle.

I'm thinking, what if I try to map everything to generic stuff if possible instead?
So I just try to save floats, integers, gameplay tags, etc. and then I map it to whatever I need when the file is loaded.

Then the Player might suddenly have a new skill node chosen in the skill tree for example, but nothing breaks. (He can even reset his skills anyway and pick what he wants)
The same for balancing puposes. If he finds an item with +7% damage for example. Instead of saving that 7 directly as a float or int, I could calculate what the "roll" number would be instead (say the item could be 5%-10% damage), and save that number.
Then even if I change the possible roll range later to 10%-20% I would just get his roll and map it to the new range?

[dark drum]

For further context, sometimes, it can be a good idea to include a save version number that can be checked before anything else is done. If it doesn't match the version number its expecting, you can attempt to convert the save data into the new format where possible.

[young meteor]

Good point.

[frosty heron]

I can only speak for my experience as a solo dev. No matter how hard I think of all edge cases between the diff between old and new save file.
In the end , users will always report bug anyway.

Considering any game or project out there have dozens of bugs, I do like to think it's just something we have to face.

Lets say you cap the level to 45 in your old patch

but you changed your mind because you think thats too high

[young meteor]

I understand (and agree)
Just hoping for some best practices or things to avoid to minimize issues.

[frosty heron]

So you changed the level cap to 30 when a user save.
But the people that plays the game before new version already reached lvl 45

so when they load their character they will still be lvl 45

You can make a patch for example in your new version that checks for character level

and if it's higher than the current max cap (30) then clamp it to 30

then re-save the save file I guess

[young meteor]

Right. So in that case a version number might be very useful to include like pattym suggets.

Then I should only have to do all that kind of stuff if the version differs.

And then save it as the new version after the clamping and what else might be needed.

[frosty heron]

For sure, but maybe there is more elaborate process in studios. I dunnoe

[young meteor]

But is there a standard answer for "how bad is it" if the save file does not match?
Are we just talking the Player might not have an item, achievement, unlock, etc., or will the game often crash and be unplayable or something?

Guess that is highly dependent on the actual issue 😄

[dark drum]

There can be a lot of edge cases for this type of stuff that normally have to be handled on a case by case basis.

[young meteor]

Right. Glad i tried to keep my scope small for this first game 😄

keyword being "tried" xD

[dark drum]

As another example, for a project I had worked on, there was a section where a car would turn up at a certain point. If the car didn't turn up you couldn't progress. There was an issue where the data for this wasn't being saved correctly.

Whilst I fixed the issue, I had to also include additional logic to check if the player had already reached the specific point where the car should have arrived and if so, trigger it and the required data wouldn't have been in previous saved.

[young meteor]

Right. I can see how that kills the experience for the player quickly

[little prism]

Hi,
I am trying to get direction vector by using "Get Unit Direction (Vector)". When I draw a debug line from moving objects the line is not aligned with original object... Can anyone point me into direction what is missing?

but if I move central object to V(0,0,0) it works like a charm

[pine bridge]

Hi, im trying to set a boolean in an array but somehow it applied to all the array. Am i doing it right?

[split salmon]

you need the Direction*1500+ActorLocation not just the direction

[little prism]

yeah, I figured a mistake in simple math...

Does anyone know how mass is affecting the "Add Force"? I am adding Force vector (0,14,0) using add force at tick to mass of 100Kg and it's barely moving - > I can see a fraction of 10th of movement every second or so

even if "accel change" is ticked to skip mass the movement is minimal but Add Impulse (at begin play) makes a big impact

[gaunt stirrup]

My unreal engine just randomly pauses moving and gets rid of my cursor every 3 seconds

Any help?

Everything was fine last night

Something's happening with my Unreal Engine where it gets rid of my cursor and doesn't let me move every three seconds for like two seconds. So something happened. I'm not sure, any@help?

how to launch a character in multiplayer?

Anyone know why "Set Material" is not causing any visual change? Is there any function I have to call to make the renderer actually respect the change?

[proud bridge]

I want to create a timer. not set a timer. the text written here that says setting an exisiting timer will reset the previous one. i dont want it to reset even if its set again, rather it creates another timer. how can I do it?

[lunar sleet]

It will create a new one if you don’t run that same line of code again and instead set another timer by event

[proud bridge]

but I dont know how many times this event will get triggered. so when this event gets triggered twice, the previous one is getting reset. if i knew that this event will only gets triggered twice i can set another timer. but i dont know how many times will it get triggered

this is an event to show what type of score i got to transmit to UI.

[narrow sentinel]

so not sure whats happening bt I seem to have an issue where if player walks through this trigger box doesn't seem like it's actually triggering

[crimson geyser]

Is it possible to make a hexagon grid based on these Cube Coordinates (not sure if I can link it: https://www.redblobgames.com/grids/hexagons/) with Blueprints?

[barren dove]

yep, I made a system that generated a hex grid, it wasn't very bad
just make a "cube grid" with every other layer offset by half the diameter and it should line right up

[crimson geyser]

I'm definitely not an expert, but isn't this the Offset coordinates approach instead of the Cube coordinate approach?

[barren dove]

you tell me

I started with a cube grid, you can see the grid coordinates on each square
I then changed the physical representation of the grid to a hex and offset every other hex row's physical actor

[crimson geyser]

It definitely looks cool haha! But I do think it is the Offset coordination. I want this:

[barren dove]

you need the hex grid first, you can calculate what tiles are within your perimeter or those lines with math

you're leaning too hard on hex grid tiles, the math behind the scenes is very, very similar, just use a square grid until you're more familiar

in my case because the entire game was in hex, i could use world coordinates, just make each hex 10(lets say) units across and I could tell what tile the walking actor was on based on simple math

at one point I put a collosion on each tile to spawn and despawn the tiles around the actor so i didn't have a million hexes loaded in memory at once (see the video) but it wasn't really necessary

[crimson geyser]

My game should be a 1v1 just on that specific grid, no more tiles needed. And someone mentioned to me that for pathfinding and calculating if an ability hits a character on a certain tile, the cube coordination is easier to use (once you’ve got it up and running haha). But maybe I can better go with the offset and see how it goes from there. Thanks for your input!

[grave crow]

Check collision channels setup

[narrow sentinel]

yeah I did that and wouldn't work, only would work if I made my own where I use Box Collision which is what the tirgger box uses but just didn't want to do it's stuff

[grave crow]

dont now what are you trying to do but you probably want queue-based approach instead

[proud bridge]

Yesss. Correct

How do I make this queue based?

Can it be solved using logical coding or there is already a function or a way to do it?

[barren dove]

if all you need is like 50 tiles, just make /offset them manually and number them

[zenith jungle]

has anyone tried to get common ui working in 3d world space. It does respond to my mouse inputs but it doesnt get gamepad focus for some reason. I have set focus on the first button element and it runs when firing the on activate event

Does anyone know what's causing this issue?

[zenith jungle]

select a few nodes and press Q to line straighten the connections and wrap them in comment boxes and/or collapse them to nodes with a small description of what the collapsed node does

Looks fine. I like to go like
Begin play
Start game
End game
Next round
In that order tho.

[icy gust]

This is a probably a really easy problem but I'm stumped so if someone can help that would be awesome.
I have a Sound set to play when my jump button is pressed and it stops playing when the jump button is released (think jetpack thrust sound essentially). Problem is that when the game starts it plays the sound immediately after loading and I want it to wait until the first time I jump to play the sound.

this is how I have it setup right now

[dawn gazelle]

Did you add the sound as a component to the blueprint? If so, there's a setting on there "Auto Activate" which would need to be turned off.

[icy gust]

I literally just found that as your notif popped up lmao

thank you

that's exactly what i needed

[faint python]

I might just be dumb because I apparently cannot figure it out. How exactly does the straight shortcut (Q) work? I feel like half the time it raises/lowers the side I don't want. I thought maybe mouse position or something but I don't know I couldn't seem to figure it out aha

[zealous moth]

more of a conceptual question: would anyone have any idea on how to reproduce bebebese like in animal crossing or golden sun?

[bronze mirage]

Does anybody know how to get a reference to the grass meshes that are dynamically created by LayerGrassTypes at runtime? i need to swap the material out at runtime, but I can't even find the actor to do it. i assume it's part of the landscape actor?

[dawn gazelle]

I've never played Animal Crossing, but am aware of what the characters sound like. You'd probably take some samples of common phenomes, then speed them up, then play each sample based on the words that the character should be saying.

[zealous moth]

@bronze mirage why not use material parameter collection and change it up?

[pulsar osprey]

yes its like this

[zealous moth]

@dawn gazelle I was hoping for a sound generating solution rather than getting a phoneme and modulating it. Then again... what other choice do I have

[pulsar osprey]

you can just make a sound for each letter and pitch shift it

itll be awful but it works

thats what cruelty squad did

[zealous moth]

Oh not animalese

Bebebese

It's 1 sound like a type writer

I despise animalese 🙂

[dawn gazelle]

Like a sound effect per character of text?

@zealous moth If the example in the video above is what you meant, then this will do it. Just make sure you have a concurrency class with max count set to 1 for the audio.

[zealous moth]

Oh snap thanks!

I didn't know where to begin but this helps a lot

[bronze mirage]

can MPCs have texture references? i was under the impression that only floats and vectors were valid in MPCs

[zealous moth]

I cannot recall but you might as well have the texture in your material and use a switch like a lerp and swap the scalar from 0 to 1

[bronze mirage]

yea that ain't gonna work, i'm not gonna hardcode every possible grass texture into my material lol

if it comes to that i'll just duplicate the landscape grass type object and override the material, was hoping to avoid a bunch of redundant assets though

[zealous moth]

I was under the impression you had 2 textures. How many do you have? @bronze mirage

[bronze mirage]

more than 2

Hello everyone,
i want to create a child actor in a existing actor in this scane i want to add a A_Elevator_light into A_Elevator which i can achieve simply by using the setChildActorClass method but the A_Elevator_Light has some variables like light color whose value i want to update on spawn, now you will say you can update from child actor template [image-2], yes, i can update their value from template but in order to do that i need to open the A_Elevator actor every time and this will change elevator class value and not only their objects.

so is there any way which i can use to handle child actor variable values on spawn ??

Set elevator light method is called by construction script

[dawn gazelle]

From your "CA Ceil Light" reference, call "Get Child Actor" which then gives you a reference to the actor, then you can cast to your class or use an interface and manipulate it as you need from there.

[trim matrix]

Okay i will check it out thanks

[zealous moth]

I made a day/night cycle and it uses a float to determine hours.
On each tick, it works fine and if I print string it, it works as expected.
On the following logic, I wanted to check if the day/night boolean is the same as the condition for daytime yet for some reason, the time always matches.

I'm either too tired to see what went wrong or my way is just wrong

wait a sec... as i type this i am seeing it. It never excludes the other hour

it should be an AND

yep, it's an AND, thanks Datura!

[spark steppe]

i think there's also a in range node

Hi! when opening projects, it open the browsers with a Fab login prompt

it is safe to login?

[maiden wadi]

It should be. This just means you opened an editor with the Fab plugin installed and enabled. You don't have to accept it either unless you want to use FAB in editor.

[trim matrix]

thanks for that i tried that and it worked now i can set variable values [image-1].

but i think the construction script of child actor ( which calls the setElevatorLight method is called before changing the variable values [image-2], because of that the values which i set in lightcolor and lightIntensity variables is not able implement in the pointlight component and that's why it sets the default values [image-2].

[image-3] i was setting red color for the lightcolor var but it doesn't affect the point light component

[steep sonnet]

Does anybody have an idea why this doesn't work fully? I am following a boat tutorial and basically everything works except the boat movement, when i press any of the movement keys just nothing happens and i pretty much 1:1 copied the tutorial, the only difference is that the code is inside the boat itself, not the player like in the tutorial, i just do not understand why the IA_Move_Boat doesn't do anything

[stone field]

Log out the force vector that is applied. Do the numbers make sense? Can also try just pluggin in values of your own, maybe bigger numbers to see if anything happens?

[steep sonnet]

by IA Move Boat not working i mean it doesn't work at all, earlier i simply plugged in a print string to it and nothing was happening

[stone field]

Maybe your input is not wired up correctly

[steep sonnet]

thing is that no inputs that are setup in the boat work. if inside the boat BP i add a Keyboard F key for example and plug it into a print string that too doesn't work for some reason

oh wow looks like it was one small tickbox in the Boat BP details, changed Auto Receive Input to Player 0 from Disabled, now the boat moves

[gaunt stirrup]

i messed up something with the snapping / rotation and now i can only look right and left not up and down

any help? i forgot what i clicked

[daring merlin]

Only took a quick glance at your post bcz of time constraints, but I'll throw it out there, anim instances have a save pose snapshot function that you can use to retrieve saved poses in anim blueprints/graphs. This may only work for that specific mesh however. If posing is the main feature, you may wanna look into poseable meshes, that give direct control over bone transforms, however you lose the ABP functionality.
If runtime flexibility isnt a requirement, you can create pose assets for meshes to save your pre-made poses. Not sure what the actors standing in certain position question refers to exactly.

[hollow pond]

is it normal for component parameters in all my actor instances to reset when I compile the blueprint class? e.g. Box Collision component has a default extent of 500x500x100, place actor in world and change the extent to 20x20x20, compile the blueprint and it resets the extent in all instances of that blueprint to the default value.
https://dev.epicgames.com/community/learning/knowledge-base/oEn6/investigating-blueprint-data-loss-issues-in-unreal-engine#retaininginstancemodifiedvalues according to this, I should not be losing this data on recompile (especially when it's not being set anywhere in the blueprint)

FInterp To for a smooth interpolation, FInterp To Constant for a linear interpolation

[rotund harness]

and i can use these at tick? with the values changing each tick?

[hollow pond]

they're designed to be used on tick, yes

they take tick's delta time as an input

Hey, using "Enable Animation Budget" in event beginplay, the animations on my character don't work. However, when I activate it through an input, it works correctly. What could be causing this issue?

[lunar sleet]

BeginPlay does not have a fixed exec time. Could be the character has not been Possessed yet or something along those lines

[narrow sentinel]

what would people call their game mode that is used at game time so when player is actually in level etc ??

[lunar sleet]

whatever makes sense to them

[narrow sentinel]

just not sure what to name it

[lunar sleet]

you have bigger fish to fry. Name it whatever, you can rename it at any time

fairs haha

[silent stag]

I tried with delay too

do i have to also use this node

🤷 realistically this is something for #animation

[haughty ember]

Hey guys, I'm looking into combining the game animation sample (GAS) into the lyra project.

I thought about trying to replace one of the states in Lyra with the motion matching in the GAS, but not sure how to even do that;
As far as I can tell in Lyra the anim bp inherit from ABP Item Anim Layer Base can only override the asset, not the actual node.
And if I create a new one, I need to override all of the anim layers, not just 1 of them.

Any thoughts?

Hey there, i'm trying to set up win condition so that when the player character overlaps with a component in the BP_WinCondition actor it wins, the problem is that the big ass hitbox on the front of the player character is triggering the win condition (and any other overlap events including the player character) how do I fix this?

[void jewel]

Can you trigger event hit from a trace, or would you have to break out the location and just work from that? (e.g. maybe event hit on some other actor is used to determine what limb was hit, not just that the actor was hit)

[dire stirrup]

you can check if actor you hit has specific tag for instance

anyone knows why im getting this error? if i connect event to my current event for instance, error disappears. i get this error every now and then. usually this works for me

Hi all !

Anyone has an idea about avoiding obstacles in the air ?

I mean I can't use NavMesh in the air

With a Flying Actor

[narrow sentinel]

Making your own logic

There is a flying ai plugin tbf that has the stuff to be able to do what your referring to

[odd kiln]

I thought about making splines between AI and Player but I don't know how to make that spline updating if there is obstacle

[odd kiln]

Or I could make a Box Trace and rotate the AI on the Z axis until there is no obstacles but I would rather creating a spline so I could have the "shortest" path. What do you think ?

[iron idol]

anyone know if Fab's "standard license" is enough to know its ok for commercial use?

[narrow sentinel]

You'd need to make a grid of some kind and then use an algorithm that can create through the grid a path

Or use box traces to trace in directions to find a path until the goal is reaches

[odd kiln]

I'll try that box traces because I don't have any idea how to make this "grid" thing lol. Thanks !

[narrow sentinel]

Well marketplace was anything on there could be used in what ever way providing stuff wasn't redistributed

Bit if what your saying is right then have epic put market place assets behind another licence paywall forcing someone to spend more money to simply use in commercial setting

[narrow sentinel]

Also there is a fab discord channel for that question

[wicked cairn]

Anyone know or have sources on how to build an achievement system? What is going to keep track of many different stats or events? Will it be a component in the player state? I’m trying to make a skill tree system that unlocks nodes based on tasks asked of the player and it needs to keep track of stuff like areas explored, things done during or before combat, stuff eaten, etc.

I know I’ll probably need to create an event that gets called during specific actions that pertain to the achievement or task needed, but figuring out how to structure this has been difficult.

Any advice appreciated ^_^

[surreal peak]

It's usually a combination of your existing systems having proper callbacks/delegates/event dispatchers for everything, and some manager with Objects.
In blueprints only land you are pretty limited in what you can do, but I would probably either work with the GameInstance or the GameState in Singleplayer, and the PlayerState in Multiplayer I guess.
Have a Component as the Manager of the Achievement Objects. It would be the access point for getting all achievements, handling saving and loading the progress either from the hard drive or the OSS if you use one (depends on the achievement itself too).
Each achievement object would handle its own state, subscribe to said callbacks, increment some values, etc. really depends on the achievement itself how they would function.

An achievement object would then have a name, an image (texture), a description, maybe some dynamically generated progress text, to display it in the UI if wanted. Then probably some key for the OSS to unlock the actual achievement. If the keys differ between e.g. steam and egs you'd have multiple.
Achievement Object, when it deems itself as unlocked, can ask the outer manager to talk to the OSS and unlock it. Or report some number progress if the given achievement works like that.

Saving and loading could be done with a single SaveGame object that has an array of InstancedStructs (they should be available in Blueprints). Manager could then ask each achievement for their progress, where each achievement can provide a custom struct if needed (due to the magics of the InstancedStruct). Might want some unique identifier to store alongside the struct to later load the data and assign it to the right Achievement.

But that's kinda all I can give you for now. Achievement systems are somewhat similar, yet vastly different between games. And blueprints, as usual, have very limited options to make things pretty and easy to work with

In c++ I would probably work a bit more with DataAssets and Instanced UObjects

[wicked cairn]

This is extremely informative!! Thank you lots for this! As you said I’ll definitely see what I can do about storing achievements in objects and having the manager activate and analyze the id of the inputted achievement when needed! I’ll look into using data assets since my game is a mixture of c++! (I’ve only been using c++ when complexity or specific scripting calls for it lol)

[surreal peak]

Sure. For the skill tree your individual object can simply talk to your skill tree system and unlock a node when it's completed

If the nodes are uniquely identified then you can easily set that identifier up as a another variable and put the skill tree related communication code into the parent achievement object. If only some of the achievements should do that you could make an in-between class that skill tree specific achievements inherit from.

If there are a lot of different combinations of unlocks but they are still somewhat repetitive and often used (like one unlocks a skill, another gives 5 attribute points, a third one does both), then either have a strong base class, or work with a bit more composition by having an additional set of objects on the achievement object that reacts to the achievement being unlocked (could be just an array the achievement loops over). Makes those things a bit more reusable.
For that stuff, Instanced Objects are a lot nicer, as you can write reusable UObjects instead of creating a bunch of BPs/Classes.

[surreal peak]

If it blocks the channel the trace is tracing for, yes.

[idle vigil]

in my card game i have this enumeration for ability cards and descriptions for them but turns out i cant access the descriptions in blueprint. Whats a good way to store this info? gpt suggested data tables which im not familiar with. just asking to see if data tables is the best option. i also read about data assets

[frosty heron]

best is subjective, you can use Data Table or Data Assets

either one will work

if this is a static information with just a key and pair value (name and description), even a Map will do the job

[idle vigil]

the map would be stored as a variable in gamestate for example and all the other bp would have to read it from the gamestate right?

also for future reference is there a data type where i could import this key value pair info from excel for example? that would be very useful

[frosty heron]

I can't answer where to store the data, it has to be in a place that make sense, and that is different per project

if you want to import to excel, then use Data Table, it support CSV import/export

[idle vigil]

alright thanks

[spark steppe]

a DataTable is pretty much a map

so rather use a data table than a variable in some BP, you'll have an easier time editing a DataTable

[idle vigil]

yeah thats what ill go with, watching some yt tutorials about it rn

I am dealing with an issue with a very slow subtle camera shake causing jarring micro snapping of the camera when it is starting and ending, like the camerashake takes over the camera controls and offsets it like 3 pixels and then when the effect ends it snaps back 3 pixels. I've played around with the fade in/out timer and all of the diffrent camerashake types, also using a timeline to fade the scale to 0 manually at the start/end but to no avail.

has anyone seen this before?
here you can see the end of the camerashake segment

Get Assets by Path works good on the other hand

[mild galleon]

hello!
i have an interface.
On the entering side, i need a reference to the target. Do i have to cast now to define that target?

i wanted to save the actor in a reference,

but to get the widget, i need to cast to it, and i cant get the "cast to" option for that widget.

okay. i have resolved it like this for now.

(it allows me to get the ref i need from a different BP actor, who already has it, the widget reference)

still, i find it unintuitive, i cant cast to it directly, and also, just for interest, i do this once in the construction script, that should be sufficient i believe (?)

if i did it "on begin play" i wouldnt be sure it works for all instances.

[green barn]

Found out what was going on, though hindsight the info i gave was way to vague probably for someone to be able to troubleshoot this. But still just replying in the 0.01% chance someone has the same problem and finds this, so what was going on is that we have a top down game where the camera is exactly on the 90° axis - looking down, and when we introduced camerashakes the camerashake rotation would send the camera into Gimbal lock, as the camera shake rotated the camera over-90° it snapped to some totally diffrent rotation values. tilting the camera by 1° so it was at the 89° was enough to give the camerashake room for tilting without overextending into gimbal lock. hope this helps anyone down the road

[cedar sparrow]

Is there any way to make the Character Movement Component more lightweight? It's hogging over half my resources when I have more than 20 characters in a level. All they have to do is walk.

[shadow flame]

Is there a relatively easy way for a packaged project to launch two fullscreen windows with different viewports? I'm building a kiosk that has two monitors and needs a separate window per monitor

[lunar sleet]

20 seems a little low for it to be that expensive, although it depends what half of your resources means, for all we know it’s half a potato. Did your profiling say it’s due to the CMC?

[cedar sparrow]

yeah. I get solid 120fps until 20 characters, then it drops to about 90fps by 50 characters. after that my game starts to crawl and everything moves in slow motion. It's just an empty level with just the mannequins walking. I have a 4090 and 9800x3d and 64gb of ddr5 ram so to slow me down takes a good amount

[lunar sleet]

Ok so you didn’t do actual profiling to see if the CMC is the problem though

It could be anything on that character

Animation is usually a culprit

You can make some CMC optimizations but most of them require modifying the source code and usually it takes a few hundred characters before it’s necessary

So first I’d narrow it down to precisely what the issue is, profile in standalone with named events ticked and so on

[cedar sparrow]

Is this not the profiler?

[lunar sleet]

That’s one of the tools yeah, but I’m talking about Insights tracing so you can see details

[cedar sparrow]

oh ok

let me look into that and see where it gets me

thanks

Hello there ^^
I am coming to you with a fun issue about collision on spline mesh components that are created in the constructions script. No matter where I set them to BlockAll (in the mesh spline node, separately after I spawned them all, etc), they still remain as ethereal beings. I found an old issue for UE4 marked as "Won't Fix", but I can't bring myself to believe, that something as simple as collision on spline meshes (that aren't even deformed) would not work or at least have a workaround.

Hey there, I need some help...
I have a simple piece of code that changes the camera from the player parented camera to a camera actor inside the level.
How can I change it back to the player camera after a 1 second delay?

I can't figure out how to cast the player camera back into being the current camera...

Well I tried something weird but it worked

Plugging the player actor directly into the view target counts as a camera actor sicne there is still a camera as a child of the player BP... thus counting as a camera actor

[wicked cairn]

I'm trying to create a Zone system for an open world with different weather in each zone.

Would it be efficient to make a custom mesh from Modeling Mode and add a component with an event for when the player overlaps, itll display the name?
I'm just trying to figure out a way to do this system and have custom colliders on my map that envelop each different zone for identification.

Any ideas appreciated!

[faint pasture]

Does it need to be that detailed of a shape?

What sort of shapes and how big?

[wicked cairn]

Basically solmething like this! It'll not be TOO detailed but obviously shaped like a polygon and have walls around the zone

Like when a player goes into a new zone in games like valheim, or world of warcraft, etc. and that information gets updated

I assumed there would be some kind of collision or walls around the zone itself stating it's information

Only way I can think of doing this is by creating a custom mesh in the Modeling Mode and editing the collision and making it into an actor for that specific zone

But then Im curious as to how they make it for games like Valheim where the zones are procedural... ;u;

[pulsar osprey]

i imagine they might use a texture to paint biomes on the map

[wicked cairn]

True, but are they like tracking what texture is on the map to coordinate to what biome they're in?

How to override a file in ue5?

I am trying to create a json file with data. i save it to my dir like this:

this is the file, it is called Game with out an extension

What if i want to create more than one file? what if i want to modify/override a specifc file?

[frosty heron]

This seems to be a plugin, so not much people would have access or use the plugin.

You better off reading the docs or join the discord for the plugin if there is any.

If you want to write a new file, we'll don't overwrite the old file.

You can increment index everytime you create a new file so it goes like file_1, file_2 and so on.

[maiden wadi]

It's worth noting that you can make a volume at runtime using the dynamic mesh components. But it really depends on your world gen code and how you're doing things. You need to know what biome you're in to set correct textures, spawn correct foliage, pick correct events for gameplay, etc. A lot of world gen just does it by generating and saving arrays of data as chunks based on an algorithm. And each grid space just contains it's own data. So whether you're sampling data from a chunk's location, a texture, or creating a dynamic mesh around the area, all work, all have bonuses and drawbacks.

[remote meteor]

Va rest is just a json + rest, pretty basic. Write file to path overrides all content everytime.

Hey guys, I got a small question
When I use the "Any Key" Node and print the displayed Key, how can I check only for keyboard keys and not the mouse buttons?

Got it, I used the "Is Mouse Button" node to make the check! 🙂

[dusky gale]

Hey mates I know this may seem lame but i really cant figure out what i have done here and it doesn't work

Supposed to be a simple Switch and Door, the switch detecting me being there and when i press the interact button checks if im there and does the function of the timeline i added (on a previous door and works)

I did it for pressure switch and worked fine i dont know what im doing wrong here

[dark drum]

Make sure the actor (in the case the door) has been set to recieve inputs from the player controller. With this sort of setup you would normally enable it on overlap and then disable it when the overlap ends.

In addition to that, you also want to make sure that an Input Context Mapping has been added to the enhanced input subsystem that contains the interact input action.

[dusky gale]

I was looking around and saw the on component overlap

is that something more apropriate ?

[dusky gale]

i put some print strings and it appears the InputAction is not doing it

here is the mapped input

[dark drum]

You need to enable input on the actor so that it'll recieve inputs from the player controller.

[dusky gale]

the actor on this context would be the Switch how could i do that ?

[dark drum]

So when it's overlapped, enable input. When the overlap ends, disable input.

[dusky gale]

ah like this ?

[frosty heron]

legacy input 😦

[dusky gale]

ye it's 5.0.3

[frosty heron]

Enhanced input exist since long time ago

[glossy holly]

hey guys i mistakenly deleted my bp class please how do i recover it (edited)

[dusky gale]

i have to use this one because thats where we were told 😦

[frosty heron]

sounds like you didn't use source control.

set one up now to avoid damage in the future

[glossy holly]

yappppp

unfortunately for me

[frosty heron]

Who told you that? and you don't always have to listen to anyone that giving you this advice

[glossy holly]

?any help

[frosty heron]

this is considered bad practice tbh, you want to handle input in a centralized place ideally.
Giving input in other actor here and there will be debugging nightmare.

[maiden wadi]

You can check the Project\Saved\Autosaves folder. But that's about the best you'll manage without source control.

[dusky gale]

i'm being graded for uni, we have to use this version because that's what we are going to load into a specific hardware later

[glossy holly]

yh how do i put it back in the folder

bcs it doesnt show up wen i lunch the engine

[maiden wadi]

Content folder is the base of your project folder. So put it back where it was in that folder.

[glossy holly]

yh i did that

i should put it in content folder

or the folder it was in content folder

[frosty heron]

we are not talking about unreal engine version though, you are using UE5 so the enhanced input is available for you.

[dusky gale]

yeah i have enabled it

[glossy holly]

aurther

[frosty heron]

I would advise you to use that instead

comes with many benefits, including more events such as triggerd, cancelled, etc.

[dusky gale]

How would i use it on this context ? like create an enhanced input im not sure what it should be doing

ah im an idiot

[frosty heron]

You can download Third Person Template and check the settings.

probably faster than absorbing videos

[maiden wadi]

How is it that so many people mess up my name? Aurther, Arthur, Arther, Authear, Authar, Author. It's literally on the screen in plain text. 😦

Gonna rename myself Steve.

[glossy holly]

lol i am sorry

[glossy holly]

@maiden wadi

[maiden wadi]

Do you know what folder it was in before you deleted it?

[glossy holly]

yh

that the folder it was

but wen i launch engine i dont see it

[dusky gale]

if i got it right, I would replace this with this right ?

How do i map which button it is tho, remember on later version i could choose which one it is

[frosty heron]

in your input mapping context

[dusky gale]

on the BP or the project settings

[frosty heron]

https://dev.epicgames.com/documentation/en-us/unreal-engine/enhanced-input-in-unreal-engine

Project settings is for legacy

the input mapping context will be an asset that you create.

[dusky gale]

ye im in there just dont see the mapping thing

[frosty heron]

it's there

[dusky gale]

maybe i have to make it mappable somehow

[frosty heron]

there is Input Action, there is Input Mapping context

you need both

keep reading and attempt first

[maiden wadi]

Not much you can do then. If replacing it from the autosaves doesn't work. 🤷‍♂️ Strongly recommend setting up a simple azure devops with git desktop for version control. Free and not that bad to work with. Alternatively a local P4 maybe.

Guys what's the purpose of the Game Instance if we can save and retrieve the data directly into / from files ?

[maiden wadi]

It's just an object that is created and maintained with the life of the game. It makes more sense if you look at the C++ implementation of it. It maintains some global runtime state, and has some global delegates and such.

[main lake]

I'm good at reading unreal c++ 😬 is it more costly to look into a file compared to RAM and retrieve / write data in it?

[maiden wadi]

HDDs are usually slower.

[frosty heron]

You never make a save and load system?

[maiden wadi]

That said, GameInstance shouldn't really be holding a ton of data. You can load SaveGames, and keep their object alive to hold the data for you.

[main lake]

what bout modern SSDs or NVMEs, etc... ?

[main lake]

nope

[maiden wadi]

Any sort of "hard drive", will always be slower than RAM access.

[frosty heron]

in the context of saving system, you want to keep reference to the save game object

game instance is one of the few object that is not affected by travel

[main lake]

isn't the save game object the Game Instance ?

[frosty heron]

nope

[maiden wadi]

USaveGame is not UGameInstance

[frosty heron]

#blueprint message

[main lake]

clicking doesn't work 👀

[frosty heron]

To re-iterate what Authaer says but simplified, GameInstance is an object that is created when you open the application and destroyed at the end of the application.

the life time is what makes the object a great place to store presistence values, such as reference to a save game object

[main lake]

but still doesn't answer my question regarding why not saving directly in the save game object, rather than using the Game Instance ?

[frosty heron]

You store the reference of the save game object in the game instance

how else will you access the same save game object if you did not store the reference in game instance?

all of others objects would be destroyed on hard travel

[main lake]

save them in a file and reload them on the new level ? 🤔

[frosty heron]

so creating another save game object? why?

why not point to the same save game object already created?

[main lake]

mhhh

[rigid fulcrum]

Take two random numbers between 1 and 100 . Let's call them
A (higher number) and B (lower number).
Need an equation where A always= zero and B always equals 1.
Everything between A and B would be a decimal.

???

[main lake]

you have a node for that called "Random Float in Range" 👀

[rigid fulcrum]

That doesn't solve the problem

[main lake]

wait your explaination doesn't make sense 😄 How can :
A = High Number and A = 0
B = Lower Number and B = 1

There's a contradiction here 😄

[main lake]

What are you trying to achieve, maybe we can help better this way 🙂

#multiplayer

[narrow sentinel]

Anyone able to help me on this, I have this bind event being done in the Enemys Behavior Tree when they meet a obstical. I bind to the disptacher and then do the connected event.

My issue is it seems even though the distpacher is firing and I've checked everything is valid that connected custom event seems to not be firing

not really had this before

[frosty heron]

Running CE fired from a delegate in BT seems very shaddy to me...

[narrow sentinel]

would a create event be better

[frosty heron]

not that I've done much A.I but doesn't sound like what you are supposed to do

a BT should handle Task, procedurally imo

why would you intercept a BT ( if it's even running, could be running different task at any point) and run something from it.

probably best ask in #gameplay-ai

[rigid fulcrum]

Ok.....
I have a temp system in my game... At colder temps things happen(1) at Warner temps things don't happen (0).
I want to be able to set the temperature range with math that always ends in an answer between zero and one (no matter what the temp range is)

[frosty heron]

between zero and one or ZERO and ONE

between zero and one means you want to take the floaing values

so why can't you use random float in range 0 - 1?

that will give you a value between 0 AND 1

[rigid fulcrum]

Because I don't want the result to be random

[frosty heron]

so what if it's 50?

is it going to be 0 or 1?

[rigid fulcrum]

Let's say at 60° your character doesn't chiver(0) and at 32 they chiver allot(1).

[narrow sentinel]

prob take like 3 days to get an answer as it seems people in there aren't the best at responsive, but to answer the other bit I need a callback from the object being interacted with so AI knows when can continue

[rigid fulcrum]

Now, change 60 and 32 and see if you still get 0-1 result

[frosty heron]

Im just gonna answer the original question

if you have minimum value and max value, use map range clamped instead then round the output

[foggy spire]

how do i align a rotator to another rotator slowly at a specified rate?

cuz lerp works as a percentage ;-;

[rigid fulcrum]

"map ranged" ..... Perfect!
Learning a new node today

Thank you!

I was trying to figure out how to do that with math

[iron bobcat]

Reposting, because it got absolutely buries yesterday.

I am coming to you with a fun issue about collision on spline mesh components that are created in the constructions script. No matter where I set them to BlockAll (in the mesh spline node, separately after I spawned them all, etc), they still remain as ethereal beings. I found an old issue for UE4 marked as "Won't Fix", but I can't bring myself to believe, that something as simple as collision on spline meshes (that aren't even deformed) would not work or at least have a workaround.

https://issues.unrealengine.com/issue/UE-93234

[main lake]

did you understand his question ? Because I still don't 😄

[rigid fulcrum]

https://discussions.unity.com/t/how-do-i-convert-a-number-and-a-range-to-another-directly-proportional-number-and-range/188399

I know that's unity but, the math would be the same

Luckily, we have a built in node to do it for us

[vale pine]

How come this options string is returning false? What am I doing wrong with the syntax?

Ah, got it

[twin oxide]

Hey 🙂

I'm trying to create a flying ennemy, that can move in 3 Dimensions. My Parent Class is a "Character" Class. With a classic "Movement Component". I don't know how to figure it out. I've tried to set "Default Land Movement" to "Flying", but it doesnt work.

My goal is to use a Behavior Tree, and use the "Move To" Task. Is that possible for a flying unit ?
Also I tried creating a "Pawn" Class instead, to add a FloatingPawnMovement component, but if I use "add input vector" on EventTick, it ignores collisions.

Thanks !

[pulsar osprey]

maybe you want to use a curve of some sort?

[main lake]

the formula is just :
OldRange = (OldMax - OldMin)
NewRange = (NewMax - NewMin)
NewValue = (((OldValue - OldMin) * NewRange) / OldRange) + NewMin

Let's take for example 50 and you want the range to be between 0 and 3:
OldRange = (100 - 1) = 99
NewRange = (3 - 0) = 3
NewValue = (((50 - 1) * 3) / 99) + 0

NewValue = 1.4848484848

[rigid fulcrum]

I'm not at my desk to try anything at the moment BUT, I believe that "remap range" is gonna do what I want

[tardy ingot]

Hello so I have a puzzle mingame that generates switches in a 5x5 grid (uses 5x5 function that takes the transform location and scale of each switch to place on the interface). I built a 6x6 function and simply set the relative scale 3D of the box itself to be bigger but now the switch positions dont align with the new interface itself. Does anyone have any clue how to do it other than creating new transform variables for the 6x6 grid?

[faint pasture]

Rinterptoconstant

[grave crow]

just lerp values to target over time?

[grave crow]

Use Parse arguments, it supports switches and args as well

[dawn gazelle]

Can you send a screenshot of the appearance of the 5x5 grid and the 6x6?

[tardy ingot]

here is the 5x5 grid compared to the 6x6

[flat coral]

Is this entirely redundant?

I think I made it in a fugue state

[jade lantern]

Hey guys, very basic query. How can I create something like this in blueprint? Single object being duplicated with an offset but with a fixed angle between all instances. I'm stuck figuring out the angle offset, as the new instance should be positioned at the end of the previous. Ultimately I want to expose the number count and the angle parameter and maybe the size of the source object ( which should maintain the relative offset ).

[dawn gazelle]

Yes. If the object is valid, then you should be able to just use the current best target. If it's not valid, then do something else.

[mild galleon]

Hello everyone, good evening.
Hello Datura!
I dont want to interrupt you, so dont mind if you are in a conversation.
I had a question.
I have a villager, and i have a tree standing in the nearby forest.
Now, imagine the villager has successfully harvested wood and brought it back to lumbercamp.
Now, he is empty again, and i want to send him to the very next nearby tree.
I assume that i have to compare world location and search for smallest vector.
but, doing that on all actors seems tedious.
Another approach could be a specific overlap on a big sphere, i guess;
but i already use overlap event to make villagers start fight or work, depending on type of other actor;
so that might not be compatible...

how would you compare the distance, to find the minimum, hence the next nearby tree?

or, would you think i should not follow this approach to check all these trees? or get a random one, instead of a for each loop?

could some sort of raytrace help?

[faint pasture]

[odd kiln]

Hi all

My Actor is following a Spline.

How can I make it to rotate on X axis when it's not going straight forward ? Like an airplane for example

[kind willow]

Maybe try the rotating movement component?

Not sure what do you mean "like an airplane" because X axis rotation would do barrel rolls

[odd kiln]

I mean like a bird for example. When a bird is rotating to the left (for example) he is rotating himself to left a bit, right ?

He is not parallel to the ground
