Its basically what you are doing here manually

tall salmon
#

oh

hexed pecan
#

Read the document page

#

Google "unity getaxisraw"

tall salmon
#

unity explains it weirdly imo

#

ill try

#

ty!

spring creek
#

You could also just do... GetKey...

tall salmon
#

getkey how?

spring creek
#

No up or down
But yeah, GetAxis is preferable

tall salmon
#

instead of down you mean

#

oh yes

#

you mean that

#

kewk

spring creek
tall salmon
#

and how does that change it?

dense tusk
#

GetKey checks for every frame the input is true

#

GetKeyDown only checks for the first frame the input is true

tall salmon
#

ohhhhhhhh

#

makes a lot of sense

#

so im just dumb

#

that also makes sense

tf is wrong with this?

I have this weird bug where if I overwrite the code during in game, dictionaries can no longer be found, they are in void start(), and could only be found or referenced if i start the game again

Sometimes clicking regenerate project files helps 🤷‍♂️

#

It can have issues on some systems. I wouldn't say that makes it shit though

faint nimbus
#

when i overwrite the script, they lose reference to dictionary

rigid island
faint nimbus
#

it is very weird UnityChanThink

fervent furnace
#

the reference wont automatically be null unless the garbage collector has bugs
this is key not found exception

cosmic rain
#

Do you have assembly reload and stuff disabled?

faint nimbus
cosmic rain
#

It's ok, but that would explain the code breaking.

dense tusk
cosmic rain
#

Hot reload and similar features have their limitstions

hexed pecan
#

Static and non serializable variables (like dictionaries) reset to default when you reload scripts

faint nimbus
#

would the bug happens also if game reloads (like changing levels)? or only happens when changing the script?

hexed pecan
#

Wdym game reloads?

#

Like restarting it?

#

Or loading a level?

faint nimbus
#

or does void start() mean the game or exe starts?

hexed pecan
#

Start is after the object was created

faint nimbus
#

im trying to replicate a similar scenario where scripts would do the same when it was edited in unity but in game, or it wont happen?

cosmic rain
#

Actually, I'm not sure if hot reload is a thing by default. Disabling domain reload shouldn't allow you to edit the script at runtime and make use of the changes.

hexed pecan
cosmic rain
hexed pecan
faint nimbus
#

unity reloads script when saving also

#

it is like dictionary becomes empty when it is reloading

#

but when i run the game again, it functions normally

cosmic rain
faint nimbus
#

hmm, it continues it for some reason, I use it sometimes to check if script is ok also

cosmic rain
faint nimbus
#

not sure if it becomes empty or it cant find it

#

but works ok if i reload the game

cosmic rain
faint nimbus
#

ah okok, but it is a scary bug, should i be worried of it happening in the game (without unity editing)?

cosmic rain
#

You can't edit code in the build, so it's only relevant to the editor. Not to mention that it's not a normal workflow.

#

I feel like you have some kind of plugin or asset that allows it

#

Because it shouldn't allow you to stay in play mode on script reload normally

faint nimbus
#

not sure how, i havent touched unity settings, but is useful sometimes UnityChanOkay

#

but also, it shouldnt happen i think

#

thank you everyone UnityChanSalute

mellow sigil
#

It's a setting you can toggle. It's off by default nowadays I think but used to be on by default.

unnamed.png
#

I suggest you turn it off because it causes more trouble than it helps

cosmic rain
mellow sigil
#

It does, if it's set on "Recompile And Continue Playing"

cosmic rain
#

Oh, didn't notice that.

#

So it's basically hot reload

mellow sigil
#

yeah but it's not very good at it so it causes issues like this

hexed pecan
cosmic rain
#

Yeah, I didn't know that was an option. Only knew about domain and scene reload options.

faint nimbus
#

I fixed the code UnityChanOkay

#

instead of .rotate, because it adds it, i dont like it adding, I used interactable.transform.localRotation = Quaternion.Euler(rotationValue);

#

so it stays like how it should be

odd cape
#

im tryign to implement an undo function to a blockpush puzzle game, any guides?

knotty sun
odd cape
#

could u elaborate a bit more

#

how do i save my game state and stuff

knotty sun
#

I presume you have a grid array which contains the current state of play

odd cape
#

i dont think so

#

im pretty new so i just follwed a tutorial for the bascis

#

this is what i followed

knotty sun
#

ok so that is the first thing you need to implement.
So you need an array which contains the state of each point in the grid

orchid abyss
odd cape
#

im also not sure how to differentiate between the different boxes

knotty sun
odd cape
#

how is GameObject[3, 3] like

#

how is that defined

thin aurora
# 
GameObject[,] grid = new GameObject[3,3]
#

Depends on use case but it's explained in the link

thin aurora
odd cape
#

is htere like an article on this so i dont have to like consntatly come back to ask

thin aurora
#

The whole point is an undo feature, right? Or is this about the video?

odd cape
#

theu ndo feature

#

i think i understand the video

thin aurora
#

And you want to undo the last change in position? The position is an XY value?

odd cape
#

yes

thin aurora
#

You can use a Stack containing Vector2 values, and each change in position is added to the stack

knotty sun
#

sounds like he first needs to learn about using Arrays

thin aurora
#

A stack is a LIFO collection, which means the last value that goes in is also the first to come out

#

Oh, I assumed that this is known considering the channel

knotty sun
#

I think not based on his earlier question

thin aurora
odd cape
thin aurora
thin aurora
#

But if arrays are new for you you should really learn about these, and collection types in general

odd cape
#

but if i have like more than one object that moved on each turn then would i have a stack of arrays or something

knotty sun
odd cape
#

for hte previous one iwas just confuseda s why a gameobjec can take a [3, 3]

knotty sun
orchid abyss
odd cape
#

do i still need to do like the save scene or the grid thing u said earlier

#

if i can just do this

knotty sun
odd cape
#

but the gameobject is not an array right

thin aurora
# orchid abyss it does

Please properly share the relevant !code so I don't have to try and retype whatever you wrote

tawny elkBOT
knotty sun
#

It is an Array containing GameObjects

odd cape
#

oh so the type in the array is gameobjects and each square is either an object or empty

#

ok

knotty sun
odd cape
#

and then this would be like each scene

#

and hten i have a stack of all of these scenes?

knotty sun
#

Scene? Each Turn

odd cape
#

yeah like the posiiton of everything each turn

knotty sun
#

yes so you have

GameObject[,] turn = GameObject[3,3];
and
Stack<GameObject[,]> turns = new Stack<GameObject[,]>;

so you can have one array per turn and add the turns to the Stack
when you read the Stack you get the previous turn array back

Hey @wicked river , we've released Muse Behavior 0.5.10, can you let me know if that helps some of the issues you had? Still happy for you to DM if needed 🙂

Also there is now a Muse-Behavior tag for questions in the #1202574086115557446 channel 🙂 (although I'll admit I keep more of an eye on the discussion pages as I mostly use Discord for personal stuff)

i have a platformer with moving blocks. my issue is that blocks can very easily move to slightly offset positions (eg 1.02), so my player and other things that move get caught on weird overhangs on colliders that are not really visible.

#

Any suggestions on a good approach to address this?

frail dust
#

I have 3 types of items which I wanna spawn, they have circle colliders and box colliders. Now I want a system to be developed such that no item should spawn very close to each other or touch each other (or appear on top of each other). The system should be aware of all items instantiating and be responsible to have a distance between every item respective of each item's size. How do I approach this?

#

why not

#

it works fine in my games

#

show what you tried and how it failed

frail dust
#

can i share my set of code here

leaden ice
#

if you want help with it, that would be prudent yes

frail dust
# 
    {
        Vector2 spawnPosition = new Vector2(xPosition, yPosition);
        // Get the collider size of the item
        Collider2D itemCollider = itemPrefab.GetComponent<Collider2D>();


        // Check if there's any coin too close to the spawn position
        Collider2D[] colliders = Physics2D.OverlapCircleAll(spawnPosition, itemCollider.bounds.extents.magnitude + minDistanceBetweenCoins);
        Collider2D[] boxColliders = Physics2D.OverlapBoxAll(spawnPosition, itemCollider.bounds.extents * 2, 0f);


        if (colliders.Length == 0 && boxColliders.Length == 0)
        {
            Instantiate(coinPrefab, spawnPosition, Quaternion.identity);
        }
        else
        {
            // If too close and attempts remaining, adjust the position and try again
            if (maxAttempts > 0)
            {
                AvoidCloseSpawn(itemPrefab, xPosition,Random.Range(-5f, 5f), maxAttempts - 1);
            }
            else
            {
                // Max attempts reached, do something else or log a message
                Debug.LogWarning("Max attempts reached. Unable to find a suitable position for coin spawn.");
            }
        }
    }
#

so i tried this

#

but the items never follow this logic

#

they sometimes spawn on top of each other as well, or very close to each other

#

basically im making a 2D endless runner game

leaden ice
frail dust
leaden ice
#

your code doesn't reflect the reality of your prefabs

frail dust
#

is this the only thing i gotta change?

leaden ice
#

well there's also the presumption here that your colliders match the visuals of these objects

frail dust
#

yes they do

leaden ice
#

you also need to incorporate the offsets/centers of the colliders if such exist

frail dust
#

what about the polygon colliders

leaden ice
leaden ice
#

either a box or circle

frail dust
#

oh

leaden ice
#

and rather than using GameObject, I would make sure there's a script on all these things like PlaceableItem and it should have a public property like PlacementCollider which directly references the placement collider

#

that way this script doesn't have to do anything like dig around in the prefab for colliders and guess which one is which

frail dust
leaden ice
#

what do you mean by that

frail dust
#

i didnt really get how to do that

#

or how would i code that with the logic I want

leaden ice
#

What part are you confused about

frail dust
#

like the whole logic

#

how would i achieve it

leaden ice
#

that's what our whole discussion has been about so far

frail dust
#

lmao

#

okay so

#

what do i do first

#

the simplest way to do that

frail dust
#

excuse me for being a little silly but can u explain that a bit more

leaden ice
#

I'm just saying all your items should have a script on the root of the prefabs

#

like

public class PlaceableItem : MonoBehaviour {
  [field: SerializeField] public Collider2D PlacementCollider { get; private set; } // assign in inspector
}```
And then this code you shared above can say like:
```cs
void AvoidCloseSpawn(PlaceableItem itemPrefab, float xPosition, float yPosition, int maxAttempts = 5)
if (itemPrefab.PlacementCollider is BoxCollider bc) {
  // do an overlapBox
}
else if (itemPrefab.PlacementCollider is CircleCollider cc) {
  // do an overlapCircle
}```
frail dust
#

would this code automatically do this for all the instances that get randomly instantiated

leaden ice
#

You would be calling this to decide whether the spot is ok to instantiate

frail dust
#

so every prefab would have PlaceableItem script, so when I reference it, what instance of the script it would refer, like to which item's script

#

because there are total 3 prefabs

#

every prefab has its own spawning script

leaden ice
leaden ice
frail dust
#

yeah

#

im making one script that works in the hierarchy

#

that manages all 3 prefabs

#

but the thing is i want to have 3 different spawn logics for all of them

#

for coins, they do spawn more

#

for cars, they do but frequently less

#

for pickups, they will have a lot of if else conditions to decide when shall a pickup item should spawn

leaden ice
#

ok but the concern currently is the placement logic

frail dust
#

yes

#

a hierarchy

#

which

leaden ice
#

so... it refers to whichever you refer to

frail dust
#

decides where to spawn an item if its gonna collide with other item

leaden ice
#

you know you make a reference like

public PlaceableItem[] placeableItems;``` and drag and drop them in the inspector for example
frail dust
#

shouldnt i make one instance of this script and put it inside the same gameObject in the hierarchy which has the other 3 spawning scripts. And this script should have all the colliders of all prefabs. then other 3 scripts can refer to this same instance

leaden ice
#

I don't see why that makes more sense than putting it on the prefab. it represents a placeable item and has information about itself

frail dust
#

i want this script to automatically get all the colliders and their size as well, because cars will have different sizes right, colliders will have different sizes, so this script will have their collider size, and then other scripts can refer to these sizes maybe

Since I have a custom physics engine, I have the luxury of being able to insert corrections or special cases into any part of the process.

#

Is it maybe better to add conditional movement to try to grid-align specific objects?
Or maybe a special case for things to not get stuck on tiny ledges? Both?

Anyone have recommended reading material (preferably with practical examples) of creating a flexible weapon system? I want to be able to create weapons that can have additional effects (damage buffs, visuals, sounds, etc).

I've used Scriptable Objects for simple use, and I get how I can use it to manage number values for the weapon. I'm scratching my head though when it comes to additional visual effects since I don't think Scriptable Objects really deal with that.

Hi @everyone hope everyone would be fine!

are you ever resetting velocity to 0?

Creating a flexible weapon system

versed spade
#

Trying to make a jet like player movement for the 2D game I am making and am hoping for some guidence. Currently I made a system that will steadly decrease the velocity after its provided some with the press of the W key, but its very laggy, looking less like it is slowing down, and more like its teleporting each step.
Here is the code:

public class V1PlayerMovement : MonoBehaviour
{
    public Rigidbody2D rigidbody;

    public int ForwardThrustSpeed = 10;
    public int ReverseThrustSpeed = 10;
    public int LeftThrustSpeed = 5;
    public int RightThrustSpeed = 5;
    public float decelerationFactor = 0.99f;

    private void Update()
    {
        //Vector2 currentVelocity = rigidbody.velocity;

        //currentVelocity *= decelerationFactor;

        //rigidbody.velocity = currentVelocity;
        Debug.Log("Current Velocity: " +  rigidbody.velocity);
    }

    public void ForwardThrust()
    {
        rigidbody.velocity = Vector2.up * ForwardThrustSpeed;
        Debug.Log("Providing forward Thrust");
    }
}```

#

#

ForwardThrust

versed spade
#

so here under my player object

#

Its a Onpress event

#

*No idea how to handle holds yet

rigid island
heady iris
#

i think Zane meant actions that you hold down for a while

#

like movement

#

you wouldn't use the "Hold" interaction for that. The Hold interaction is used for an action that fires after you hold the button down for long enough

heady iris
#

what method are you actually calling, though? it has to take an InputAction.CallbackContext

#

and ForwardThrust doesn't

versed spade
#

I co figured it through the events dropdown, so I made one under my player action map within that dropdown and added the Forward Thrust function to it. Not quite sure about the Input Action method as the guide I followed didn't mention it

rigid island
#

Ohh I only learned the way I've seen done on Unity FPS demo, so for held button I do as follows : I set Action type to Value instead of Button then use bools like so
Since i use Send Messages mode btw.

 public bool Fire;
 public void OnFire(InputValue val)
 {
     Fire = val.isPressed;
 }```

#

Do you want to constantly set the velocity as long as the button is held?

it sounds like what you really need to do is distinguish between things whose colliders will not change and things whose colliders will change

it is just a monobehaviour that needs to be notified when the shape is different

so when exporting to WebGL, none of my videos work.
google tells me i need them in a folder called "StreamingAssets".
for some reason, whenever i put a video file into that folder, its immediately corrupted. putting video files elsewhere in my project works out fine.

im on linux and i know it comes with some weird things with unity's video support so it might be important.

modern creek
#

webGL doesn't support reading from files, so you'll need to download the file using a WWW request

tawny elm
#

so have a link instead of a file on the videoplayer component?

#

also these are the errors that it gives me with the corruption stuff

image.png
modern creek
#

I'm not familiar with the component (VideoClipImporter) but you'll probably need to write the code yourself to get the byte stream and send it to that component

amber forge
tawny elm
modern creek
#

If the app were a windows app you could just drop it in /StreamingAssets and read it in code - but IO operations aren't allowed in WebGL

tawny elm
#

heres a video showing the weird thing with the folder incase this provides more information (ignore the goofy pics of my mate, i was using them as placeholder assets)

modern creek
#

I'm not familiar with this component but it looks like you should just be able to drop those clips in your /Assets somewhere, link them to the component, and do myVideoPlayer.Play()

tawny elm
#

they play in the editor

#

but in WebGL they juts do nothing

#

some youtube video said i just need them in the StreamingAssets folder but thats being weird and glitchy as i have shown

modern creek
#

Don't put things in StreamingAssets - the video clips are imported by unity (I imagine) and compressed into a format that it can use.. but in StreamingAssets - it's a special folder that says to unity "no touchy" and it won't import them (or do anything with them at all)

tawny elm
#

ok that explains the corruption

modern creek
#

well "some youtube video" is probably not a great source 🙂 but if that's what the youtube video is telling you, it's probably also saying that you'll be needing to read in the content of the clip via code

tawny elm
#

for him the videos just import normally with no corruption

modern creek
#

it's not really corruption, per se.. it's more that it's not importing the clip in a format unity can use in that folder

tawny elm
#

so i figured i had something very wrong

tawny elm
modern creek
#

So you'll need to read up on VideoClipImporter and do it that way

#

And it even looks like the docs say specifically that you need to use video clips via URL in webGL:

image.png
#

So yeah, you'll have to upload your video clips as separate files from the game, and get the content via a URL.. so look for tutorials on that (how to download a file with C#, how to use a webrequest in unity, etc)

tawny elm
#

so do you think that setting in the component would be it then?

image.png
#

URL

modern creek
#

maybe? I don't know that component but.. read the docs, follow the instructions, try it out and see :p

tawny elm
#

for some reason the "browse" button for the url is a file explorer thing

#

ill just upload the video somewhere and use that

#

as you suggested

#

jesus christ ive only got half an hour to sumbit this these videos better bloody upload : ))))

solemn raven

hi i keep getting weird false warning " variable is assigned but its value is never used" it's actually being used, if i remove the variable i get an error right away

tawny elm
heady iris
# 
int x = 1;
x = 2;
#

that's the most likely scenario, at least

#

Even if you assign to the variable again later, you never actually use it

how do I make this variable nullable, meaning it wont always be assigned.

grave tundra
#

GameObject? game2; ?

cosmic rain
gloomy rover
#

I wanted to not show on the console the errors, do I just ignore it?

cosmic rain
#

No, you handle the errors

#

It being nullable, doesn't mean you can ignore errors

Make null checks before accessing the variable

when i have to go and implement a new system, i find it easier to do a little sweeping up than expending the mental effort implementing the system

I know the limit for vertices in a mesh is 2^16... is there a limit to the number of triangles in that mesh?

Hi, I'm currently using a for loop to add sway to multiple child Transforms using this code:

    {
        float mouseX = input.LookInput().x * (inverse ? swayMultiplier : -swayMultiplier);
        float mouseY = input.LookInput().y * (inverse ? swayMultiplier : -swayMultiplier);
        Vector3 targetRotation = new Vector3(mouseY, mouseX, 0f);

        // For some reason, this stops working after switching weapons
        for (int i = 0; i < targetTransforms.Length; i++)
        {
            targetTransforms[i].localRotation = Quaternion.Slerp(targetTransforms[i].localRotation, Quaternion.Euler(targetRotation), smooth * Time.deltaTime);
        }
    }

Only one of the targetTransforms is active at a time, but I've noticed that sometimes its rotation will just stay completely at 0,0,0. This is just running in Update with nothing else on the script. Any ideas?

cosmic rain
#

What's the smooth value?

crisp bronze
#

The interesting thing though is that despite the other targetTransforms being inactive, their rotations still get adjusted (which I would expect from the for loop), but the currently active transform doesn't. Weird

#

I can "fix" it by adding the script to each individual transform, but that seems needless

EDIT: This has been fixed by setting the Animator component on the targetTransforms as "Root Motion". Not sure why that fixed it since I don't use any root motion on the transforms but whatever...

Hi! So I've been trying to make a backup of my project. I have had no problems making or opening a backup before. However, recently after switching to Unity's newer input system. I have been getting errors when opening backups in regards to Unity's input system. My normal project is fine, this only shows up when I try to open my project backup and it opens in safe mode with these errors. It leads me to believe that something is wrong with the PlayerInput. Does anyone know the solution to this problem?

mightve found two problems , whenever i grapple forward then change my direction backward and grapple then , sometimes the player wont jump to the position but backwards , and the second problem at the end seems like the rope doesnt get destroyed after grappling , its not there visually but it still makes the player not go anywhere , only within the grapples maxDistance radius , im not sure how to fix it

lean sail
# wind wren mightve found two problems , whenever i grapple forward then change my direction...

you may have to clarify more, like where these issues are in the video because its really hard to see whats wrong. Im assuming the first issue is due to just physics, the player has velocity in one direction and then the sprint joint is not strong enough to immediately force them in the grappling direction.
Did you get this code from somewhere? it looks like standard youtube hardcode mixed with AI comments

wind wren
#

Also you mentioned one of the issues , the player if he grapples forward then changes direction backwards and then grapples , sometimes the player doesn't grapple to the direction or it sends the player back. The second issue is the rope seems to still be there even tho it's not there. Like it doesn't let me move after I hit the grapplers maximum distance radius so I can only walk in that radius

#

Not really sure how I can explain it better. But I hope you understand somehow

lean sail
#

yea meant spring joint. I havent seen Dani's content but dave's has always been just duck tape and glue while putting on a brackeys impression. Probably better off to not use his stuff and just create your own.
The first issue to me still just sounds like physics as i initially described, where the players existing velocity messes with the joints attempt to bring it closer. If you want it to feel snappy, then maybe set the players velocity to 0 before creating the joint.
The 2nd issue sounds like you could really use a state machine here, or at least something similar rather than all the code being just mixed and matched.

Hopefully setting the players velocity before creating the joint fixes the first issue lol

So I recently added an action buffer system to my game. But I have been running into some problems with it when I playtest it versus when I build it. I have a feeling that it has to do with the way I made my system so I was actually wondering if anyone had any resources or tutorials for a good action buffer system. I can't seem to find one the fits my game.

GetComponent<T>() is not working in Start()
after running a few tests, it turns out GameObject.Find() is working just fine, but grabbing the script component seems to go wrong
ignore the weird objectC stuff, it works the same

image.png
#

I have no idea what's going wrong...

#

i feel like i'm missing something big

#

also, the code used to work, but some magic caused it to fail. I still haven't restarted Unity to test if something went wrong there

mellow sigil
#

For one that's not GetComponent<T>(), that's GetComponent(string type)

#

and elaborate what "not working" means

icy depot
#

oh, that's a different class, it just looks different

#

the string finds the object, it works th esame

mellow sigil
#

what?

icy depot
#

in essence, the moment I get the component, it returns null

#

so I'm stuck with a null reference

#

this is the objectC jargon

image.png
#

im gonna remove it someday, it used to be my idea of splendid code

#

caching all my objects and connecting them to a string dictionary

mellow sigil
#

ok but does it work with the standard GetComponent? If it does, the problem is with the cache manager

icy depot
#

unfortunately, nope

thick terrace
#

so can you be sure that the object returned by that is still valid etc? if you're caching the reference maybe it's old, the wrong object, etc

icy depot
#

that was part of the tests i ran before coming here

#

GameObject.Find("GameUI").gameObject.GetComponent<GameUI>(); returned null, yep

mellow sigil
#

Then you'll have to show the inspector of the object and the code you used

icy depot
#

i still havent restarted Unity, this might be some silly error

if that was the problem, sorry for wasting your time

#

restarting unity didn't do anything unfortunately

#

attach the debugger and have a look at the object returned by GameObject.Find("GameUI"), you can see which components it has there in case it's different at runtime for some reason

i'll check

#

wait, attach the debugger?

or put in logs, whatever floats your boat

icy depot
#

nope, UI is UI

in fact

it's returning that little UI object

for some reason

this is just conjecture, but see how the parent Game connects to the child UI? there's no way...

#

well, none of your objects are named GameUI 🤔

icy depot
#

it's below Cursor

thick terrace
#

oh, right

icy depot
#

I'm going to try seeing what changing UI's name does

#

From this issue, I got the following: If you have a parent named Bob, and a child named Sally, doing GameObject.Find("BobSally") actually gives you Sally, according to this issue

#

this shouldn't work, but it does

thick terrace
#

yeah, by the docs you should have to write "Bob/Sally"

is it possible to change whether it's the cursor or some other object that collides with a Button? without using colliders*

#

I have a custom cursor that does funny things, such as changing size a bit when clicked (an animation), and being able to change sensitivity in-game

#

Unfortunately, it doesn't align with the system cursor, and as a result the button picks up the cursor information of a hidden cursor different from that which the player sees

#

I was hoping I could trick unity's Buttons to look at the custom cursor instead of the system cursor, without having to rely on colliders

# wicked scroll How can we help you find a system which fits your game if you didn't tell us any...

Sorry just any basic buffer system. My current one is a little weird. The gist of it is I have a queue and coroutines for blocking an action. For example, playerController.StartDashLockCoroutine. This method would be called in other scripts usually in the logic for another action. For example, I put it in my MeleeAttack logic and it's telling how soon the player can dash after attacking. It honestly works fine in the playtest, but the roadblock I have is that the time does not match up in a build, which leads me to believe that it is due to the logic behind the execution of the buffered actions in the update method. I kinda just thought of this method of action buffer just because I didn't really find that many tutorials or resources.

Update and the coroutines are located in my playerController, which acts as a state/action manager

there is an options list

I need to update the list (and for it to actually show in the dropdown) based on the text in an input field

you can create options and add it to the list

How can i do curve based procedural recoil system? have any tutorial for this?

hexed pecan
#

What I do is I have a struct, RecoilImpulse. It has knowledge about the curves it uses and its start time
Every time the gun is fired, I generate a new RecoilImpulse and add it to a list

#

Then in Update/LateUpdate I sample each impulse and their animation curves, and rotate/move the gun according to those

#

And remove the impulse from the list when its startTime > Time.time + impulseDuration

Hmm that look's good way. I'll try it 🙂

Hey guys, I'm moving a game object that is a child of HorizontalLayoutGroup (using OnDrag and changing the loacalPosision), and when OnEndDrag is called I'm trying to reset the position of the object to the position that it started with, I tried storing that location and manually change the localPosition, but it's not resetting to the location that intended When I was trying to figure out I noticed if I paused the game And just moved that child with the mouse it will try to move but will rest to the location that I want (the inforced location by the laoutGroup), Any Idea if there's a function that I could call It will reorder the children?

And I cant use character Validation because "." is correct separator and "," is not correct one and I cant use dot at all when Character Validation == Decimal.

clever leaf
#

but it does not mean that it will update in real time

fervent furnace
#

then it is nothing related to the tmp dropdown
if you need updating something dynamically look at the callback of tmp input field

I figured it out already, it had nothing to do with the input field but with the fact that refreshing that damned dropdown is tricky

Surprisingly I cant find anything on this: I have an object moving towards a transform but the issue is I don't want it going through the ground. I went at this with spherecasts which.. partially worked? It worked at first until the spherecast would constantly hit the ground and never move again

I suppose what I should be asking is if there's a more efficient way to do what I want to do that actually works?

#

I'm not asking for code just pointers in the right direction

#

It cant be a rigidbody by the way no objects have one

dawn mauve
#

Can anyone point me in the right direction on how to implement Strategems from the game Helldivers/Helldivers 2? A player holds a button (say left bumper) which lets them input up, down, left, right. If they input a correct sequence of input they can use an ability.

For the uninitiated, you can see the mechanics in this video (ignore the speaker): https://youtu.be/IxrZ5MYM4SU

How would I even begin to implement such a system? I can only imagine how monsterous the if/else if/else statements would look if I went with that approach

quartz folio
#

Why would it not just be an array of buttons and a current index within it?

dawn mauve
quartz folio
#

That's literally what I'm saying

#

array of keypresses and the one you are up to is just an index within that

dawn mauve
#

Erm… I mean there are like 40 stratagems each with a unique sequence (4-8 directional inputs). Assuming a player could input any valid sequence from the 40 options, how would I know which stratagem the player wants to use?

quartz folio
#

Another loop. There's 40 of them, that's nothing

#

If you had thousands I would suggest a quadtree, but you don't.
You could have a set of currently valid indices into all of the options, and whittle that set down until it is 1 long and the current length is the same as the length of the last option left

dawn mauve
#

Erm, I'm still not understanding the solution you're proposing

fervent furnace
#

4-8 input should be nary-tree btw

#

one treenode can have 4 -8 children

dawn mauve
#

I'm curious about the "another loop" solution though.

quartz folio
#

If you want to do that, that's fine. Personally I wouldn't think it even necessary and would just loop over the options and compare them with the current sequence, whittling down a set (which could just be a list)

dawn mauve
quartz folio
#

Yeah, and you'd only need to check the latest keypress at the index in the array of inputs

dawn mauve
#

I'm following.

quartz folio
#

Building a tree also works and may just be easier, it doesn't have to be a performant version and can just be class references

fervent furnace
#

tree traversal should be easier then maintain bunch of candiates.....

surreal blaze
#

you could literally do it with a bunch of bools

🤷 at this scale literally any implementation works

Hey, I am currently working on a small game with a friend for a school project. its going fine so far and we have implemented our first networking solution.
it uses gRPC for normal communication (requests, logging in, fetching servers, etc) and uses a TCP Socket for real-time data such as movement updates when on a server.

The Problem we have now: every time a player moves the Memory jumps by atleast 2GB, I made a Memory Snapshot and noticed that most of that is "Managed Memory" marked as "Unused Heap space" is there a reason why that happens? is that somehow preventable?

dawn mauve
leaden ice
#

Unused heap space just sounds like the game is reserving heap memory for later use. It's probably the engine eagerly gobbling up available memory and probably hardware dependent

south hawk
#

for each move. but it doesn't happen when packets are sent but only when they are received

leaden ice
#

that being said - TCP is not generally suitable for realtime data, most realtime frameworks would be built directly on UDP

south hawk
leaden ice
#

ok yeah that's not normal

#

Are you using the memory profiler?

south hawk
#

yes

#

I will send a screenshot in a sec, just had to force quit unity

#

and before someone asks: yes it also happens after I build the game

leaden ice
#

go to the other tabs and dig into it

heady iris
#

I don't see "unused" here. do you mean the 2.12GB "untracked" section?

leaden ice
#

i.e. the All Of Memory tab

south hawk
heady iris
#

ah

south hawk
#

that's from the all of memory tab

#

its reserving it for some reason

#

but it never stops reserving

#

it continues until the game is completely unresponsive

leaden ice
#

Well I don't really know how to get better details here but maybe sharing your code would shed some light

#

seems like you have a pretty serious memory leak of some kind

south hawk
#

well I don't really know where to start, I can start sending some movement related code snippets maybe you spot something off

#

trigger warning tho: the code is meh

dawn mauve
leaden ice
south hawk
#

I really hope you guys find something that seems weird

leaden ice
#

Well one thing to note:

var buffer = new byte[_client.ReceiveBufferSize];```
Are you customizing `ReceiveBufferSize` here? By default it's 8KB which is a huge amount of data to allocate for every packet you receive
#

that can add up quick

#

#

#

Can I ask a silly question - why are you building the netcode here from scratch?

thick terrace
leaden ice
#

Just overall I'm seeing lots of inefficient/questionable things like the use of managed strings over the network, use of TCP, use of json serialization/deserialization

#

you will save yourself lots of headaches if you used a premade network framework

heady iris
#

TCP is a bad choice for multiplayer.

#

A single lost packet will completely block the stream.

south hawk
# leaden ice Can I ask a silly question - why are you building the netcode here from scratch?

Well the biggest reason is: Learning purposes.
But the other one is: there is nothing similar to what I am trying to build.
I want to have a standalone backend responsible for all the user management, stats, etc.

And have the possibility to self host each individual game server.
the current setup is:
Once a game server starts up, it contacts the Backend (which we call Central) and lists itself on the public game server list.

south hawk
heady iris
#

it provides a solid transport layer

#

there's also Unity Transport, too

south hawk
#

maybe its worth mentioning our current backend (which works 100% fine) is written in kotlin

#

GameNetworkingSockets do not have a Java / Kotlin binding

leaden ice
#

self hosting is possible with frameworks like netcode for GameObejcts and Photon Fusion

south hawk
#

Right now the biggest problem is really the memory leak. Switching to UDP is not that hard and probably won't solve the issue

south hawk
#

it works fine otherwise

#

its just the memory leak

leaden ice
#

I'm not saying discard everything you have, just an idea to consider

#

but based on what I'm seeing you're going to have a LOT of hurdles in front of you for realtime interaction

#

and this is a wheel that has been invented already

south hawk
south hawk
#

Movement is synced perfectly and with very little latency (we will implement interpolation once we fixed the leak), Connect and Disconnect events are instantaneous and our very quick weapon demo also worked fine.

leaden ice
#

try reducing the buffer allocation and see if that makes any difference

#

if it does it's a signal that's the right direction

south hawk
#

any suggestions on a value?

knotty sun
# south hawk any suggestions on a value?

none of these

var buffer = new byte[_client.ReceiveBufferSize];
                var bytesRead = _stream.Read(buffer, 0, buffer.Length);
                var packet = PacketUtils.Deserialize(buffer);

should be variables local to the while loop

south hawk
#

Also wouldn't UDP require the client to port forward in order for the server to be able to send data to the client?

south hawk
knotty sun
#

yes, but the variables involved should not be, you are just allocating more and more memory every loop without ever releasing anything

south hawk
#

so like this?

void WaitForMessage()
    {
        var buffer = new byte[1024];
        int bytesRead;
        Packet packet;
        try
        {
            while (_isRunning && _client is { Connected: true })
            {
                if (!_stream.DataAvailable) continue;
                bytesRead = _stream.Read(buffer, 0, buffer.Length);
                if (bytesRead <= 0) continue;
                packet = PacketUtils.Deserialize(buffer);

                switch (packet.PacketType)```?
knotty sun
#

yes, now when you use the variables the previous incarnation will be released, this is basic memory management which you should know if you are doing network stuff

south hawk
#

anything else I can improve?

knotty sun
#

I'm not going to go through your code, but now, at least, you know what to look for

south hawk
#

unfortunately those changes did not help at all: just after like 4 seconds of movement

How do i seperate colissions properly? I have 2 handlers, attack colission handler and body colission handler. In body colission handler, player dies when it touches an enemy. On the attack colission handler, player attacks layer and enemies layer interact to detect hit attacks (by the player). However, when i attack an enemy, my player dies because the body colission is triggered. Ill send pics of my setup.

#

Question: If i have 2 objects, 1 of them is a player which has a body colission handler and is on layer "player". This object has a child which has an attack colission handler and is on "PlayerAttackHitbox" layer. The 2nd object is an enemy, the enemy is on layer "Enemy" and collides with both other layers. Why is my body colission script being triggered when a colission between the attack hitbox and enemy layer happens?

lavish frigate
#

My root object has a lot of children, likes sprite or interaction indicators. If i move the RB to a child object, how would i move the collective group of children?

leaden ice
#

Generally the RB should be on the root

#

Why do you want to move it to a child?

lavish frigate
#

Because my RB is triggering undesired colissions, even though my children have seperate hitboxes and layers

#

I dont want to move my RB from root, but i do need to seperate colissions

#

My enemies are triggers, and my player hitbox is not. So im using entertrigger func to determine how to handle colissions. This leads to my attack move box trigger to also pickup that we are hitting an enemy and the player should die. But when i hit the enemy with an attack move box, the enemy should take damage and player should not die.

leaden ice
leaden ice

#

It seems all of my triggers are called when one of them hits an object. I would however like to only call the script attached to the trigger object. Is this possible?

little meadow
#

That's how it works by default I'm pretty sure... so something's off with your config, I'd guess

#

Are you sure there are no other colliders/triggers involved? Maybe the trigger gets triggered from something other than what you expect.

#

You can do a small repro scene just to test how the physics system behaves, but am 98% sure that if you have a collider + script somewhere not on the root, you would only get triggers events for that specific collider

yep.. that's... pretty much what I said. 🙂

faint nimbus
#

but problem is, I can't seem to put it in my raycast code or integrate, i get confused UnityChanDown

modern creek
#

yeah so.. probably start with something simpler.. this is definitely not a trivial thing

hexed pecan
#

Plane.Raycast exists too. No need for a whole plane object and 'lever plane layer'

#

Just a side note

faint nimbus
#

can there be two different raycasts?

#

or no

#

ah wait

hexed pecan
#

Raycasts are not objects, they are methods

faint nimbus
#

Plane.Raycast means, the raycast from the Plane?

hexed pecan
#

And yes ofc

hexed pecan
#

Or a stuct I think

faint nimbus
#

it is not physical? or I need to put the plane thingy

hexed pecan
#

It's infintely wide tho so you would need to check for distance

hexed pecan
faint nimbus
#

ah okok UnityChanOkay

#

but how to visualize, not sure how it is rotated

hexed pecan
#

The normal determines its rotation

Hi, does anybody have a script for auto card positioning like big cards games have? It would take forever to do it by myself to look good.

#

I mean in hand

#

You draw a card and it is getting placed somewhere, different depending on amount of cards you already have in hand.

#

like here, the position of cards is different depending on how many cards one have

frame_0003.png maxresdefault.png
latent latch
#

you can do it, I believe in you

signal moon
#

sure i can, but it would take a big ammount of time

hollow swan
#

i tried but it just don't work

last coyote
#

anyone used addressable asset pack?

signal moon
#

and since it is something that many card games have, i think there is a ready script somewhere

knotty sun

somber nacelle
#

oh god why are you calling GameObject.Find every frame

knotty sun
#

So why are you using transform.position when you use rigidbody?

quaint rock
#

just drag in the reference, no need for find

#

even if you did need find why every frame

hollow swan
knotty sun
#

man, do you seriously expect us to work with crap?

hollow swan
heady iris
#

yes, and things are failing because you're searching for a random game object by its exact name

knotty sun
#

we know what you are trying to do and you have been told how to do it, but that code reflects none of that

hollow swan
knotty sun
#

why would I care how it was?

hollow swan
hexed pecan
#

Didnt I just show the code?

#

That is for calculating the new velocity

hollow swan
#

that not working sadly

hexed pecan
#

Show what exactly you tried

hollow swan
hexed pecan
#

So is this script on the portal?

#

Other is the player?

hollow swan
#

yeah

hexed pecan
#

Orange is other portal?

hollow swan
#

other is the object touching the portal

hexed pecan
#

So the thing you want to teleport

spring creek
hexed pecan
#

Get other's rigidbody, and set its current velocity to what I said earlier
So that would be orangePortal's transform forward, normalized, multiplied by the rb.velocity magnitude (so that you keep the same speed).

knotty sun
#

also still using transform when he has a rigidbody

hollow swan
#

ok gonna try

hexed pecan
#

Yeah. Should use rigidbody.position to teleport it instead

hollow swan
#

i just done -test and not it bringing me the right way thanks dude ^^

how should I fix that

somber nacelle
#

for starters, why are you saving them as individual floats instead of just Vector3

rigid island
leaden ice
sudden stump
#

Can't think of a script to place that

leaden ice
#

Put a script on the prefab

#

put the variable on it

#

I would call the script Projectile

pliant sapphire
sudden stump
#

But why have a projectile script with nothing except one variable?

leaden ice
#

You could also name the script OwnedObject or something of that nature, and it could be reusable for other things that have owners too

sudden stump
#

Can't I just call the script ProjectileOwner? But I feel like having a script with, literally, just one line of code is bad practice

leaden ice
#

You can call it whatever the heck you want

leaden ice
#

You'll likely find that more than one thing will live in this script anyway

#

Generally a projectile would have several variables on it

#

for example DamageAmount

#

Owner

#

any other properties it needs

sudden stump
#

Already have many of those other properties somewhere else

leaden ice
#

where is the "somewhere else"

sudden stump
#

Damage is handled through a DamageOnCollision script

#

Movement is handled through ProjectileMovement

somber nacelle
#

you've got the wrong using statement

pliant sapphire
#

how do i assign x,y,z position to vector3 variable in GameState

leaden ice
pliant sapphire
somber nacelle
#

use the correct Vector3 type. not the one from System.Numerics

rigid island
#

Vector3 from UnityEngine not System

sudden stump
#

Performance wise many of them don't even have an Update or Start function so it won't affect anything

leaden ice
rigid island
leaden ice

I suspect you're not near either of those thresholds

sudden stump
leaden ice
#

there's no hard rule

#

it's subjective

rigid island
#

no..

leaden ice
#

personally I probably would have just had a Projectile script that does all those things you mentioned (movement, ownership, damage on hit), but depending on the structure of your game you might have objects that only have some of those features, in which case it makes sense to separate them out.

rigid island
#

my guy do you know what a namespace is?

So i have 3 box colliders on seperate children, 1 small and 2 big ones. Both are a child of the same parent. When big box collider 1 gets triggered, the small box collider somehow also gets triggered. When big box collider 2 gets triggered, the small box collider also gets triggered. The big box colliders do not trigger eachother. The small box collider is not touched for sure. Does anyone know about this problem or can help me figure out the cause?

Hello everyone!

I am currently working on my dialog system. The goal is that I want to pause the game time while the player is in dialog. With the use of Time.timescale = 0f this works perfectly.

Now I'm faced with the problem that I don't know exactly how to avoid the enter keys globally and cleanly.

The player should only press the space bar, all other inputs do not react. This behavior should continue until the dialog is closed.

How would you implement such a system? I know I could basically set an enum state and create an if statement for e.g. the items, where I check "if player dialog state then return void".

But I wonder how I should implement such a system in larger projects where you have many keybinds.

Does anyone know a concept for an input manager to solve this?

somber nacelle
#

use an event that enables/disables your input

simple egret
#

You'll need to install com.unity.jobs manually from the Package Manager to try and fix it.

I am working on a visual novel rpg. Things I have done so far are room navigation, inventory, and parsing from a text file to display dialogue. Currently when the you go to a new room it just reads the text file assigned to that room. My problem though is with what I think is called progression. How do I structure my game so the game knows what the current state is in. Most games have this progression that as you do things npcs and the world react. How do I do this and keep track? For example I killed a boss and return to a previous room and it triggers a new scene with the npcs there.

quaint rock
#

save data, when you beat a boss, save a boolean somewhere that has happened, when you reach a checkpoint similar idea

#

the other logic can check this data to decide what to show the player or do next

modern phoenix
#

do I need a new dialogue file for each thing like if a have a certain number of items in my inventory?

leaden ice
#

The idea of a "dialogue file" is going to be pretty bespoke to your system. How did you define it?

#

how did you design it to be used?

modern phoenix
#

In a lot of visual novels you have a file like so
'''
Name: "Dialogue" [Emotion, Movment]
'''
And you parse them to display on screen

quaint rock
#

also in this kinda game, like a telltale style game the dialog is more addative. its not 1 totally pre writtne thing tossed at the player

#

but might play 5 of 6 dialogs all after eachother based on the current game state

#

also generally ends up being more of a tree structure where it branches based on game state or certain options

#

then maybe later in the story closes back in on its self

modern phoenix
leaden ice
#

sure but real visual novels are going to get very complex

#

when there's branching and state involved

#

the graph can be pretty complex and a "lets make our first VN" tutorial is not going to get into that stuff

quaint rock
#

so the first studio i worked at was doing a telltale style game

modern phoenix
#

I haven't gone through the whole thing but It seems he is making something very linear. I want to know how to incorportate gameplay into it if I have to juggle alot of variables like an rpg.

quaint rock
#

yeah the dialog tree by the end was enough to cover the walls of the entire office

leaden ice
#

suffice to say you will basically need a way to have conditionals and the abiulity to jump to another labeled place in your graph

Packages/assets are separate. At worst you pay for the asset once, else it's free

well that is only showing installed stuff

it benefits from some pacakges but it not a package

#

you will just want the collections and burst installed to get the most out of it

#

@gloomy thicket desc of that package is that it provides additional jobs types

#

You can add it by clicking the + at the top left of the package manager -> add package from git URL and then input com.unity.jobs

#

Otherwise I think if you enable preview packages from project settings -> package manager, you'll be able to see it from the package manager

could be a untiy version thing too

Is this actually good practice or is it overkill?

I was just having a discussion about this, but ideally if you're doing component searches every Update() or in between, it'll always linear search through the specific gameobject. So, if you have a single gameobject packed with garbo, it'll searc through every single one unless you divide the search a bit more.

spring creek
latent latch
#

Best solution? Layer mask the gameobject with a single component that provides references to other components.

It's very different from traditional object-oriented programming (which unity's design pushes you towards)

sudden stump
#

Isn't inheritance generally outdated nowadays and should be used only occasionally when you need it?

spring creek
heady iris
#

I would not call inheritance "outdated"

quaint rock
#

its a approach i persnally prefer to not lean much on inheritance

#

but its still a tool that can help at times

sudden stump
#

Well, composition removes the need to manage any inherited class too much

quaint rock
#

they do not solve the exact same problems

sudden stump
spring creek
latent latch
#

inheritance helps grouping behaviors, but grouping too much can be problematic

#

you can totally not use inheritance but that means you end up using more comparison logics

sudden stump
quaint rock
#

also its not 1 or the other, like my programming style uses what is most readable and does the best job for each situation

spring creek
quaint rock
#

some of it is very functional, some very composition based and even some oop stuff as its needed

heady iris
#

if you don't use inheritance, you don't use inheritance

#

use inheritance when you need polymorphism. use composition when you need to build things out of small features.

quaint rock
#

like i use langauges that dont have it, and get by just fine without the feature

sudden stump
quaint rock
#

but still make use of it when it is a tool i can use if its suited

latent latch
#

inheritance is technically more performant since it helps lessen ambiguous objects and what they contain, but it's just harder to work with (well, it's more that it's hard to deviate from your original design)

spring creek
sudden stump
#

Well you said it's nonsensical

spring creek
sudden stump
spring creek
#

It's ambiguous and nonsensical.

quaint rock
#

it was kinda implied calling it outdated, but really things never get truly outdated

sudden stump
#

Regardless I didn't come here to fight over inheritance

spring creek
quaint rock
#

concepts like composition are older then inheritance and getting popular again

#

more I use oop the more I prefer just popping out crappy one-track minded python scripts and getting done

sudden stump
#

My original question was whether breaking scripts into even smaller ones for composition (see above examples) was worth it or the performance would be overkill

spring creek
quaint rock
#

as long as references are properly cached

heady iris
#

Composition can produce very flexible games.

quaint rock
#

just dont worry about performance, you got a profiler you can use to indentify problems if you have one

heady iris
#

I recently took the plunge on breaking my monolothic "player" and "enemy" classes into an Entity class with a bunch of Modules on it

quaint rock
#

also how far things are broken up is up to you

heady iris
#

it's been a big win overall

#

It does mean that you have very few guarantees, though

quaint rock
#

i persnally feel you can share funcnality better this way then with inheritance

heady iris
#

if I have an Entity, all I know is that it has:

  • a brain
  • a locomotion
  • a body
latent latch
#

absolutely

heady iris
#

Everything else must be checked.

sudden stump
heady iris
#

it might be a player, a lever on the wall, or a spectator

latent latch
#

my rule of thumb -> don't derive more than 2 deep

quaint rock
heady iris
#

The enemy wanted to attack every other entity

#

it failed to actually find a plan, but it was wasting its time

quaint rock
#

though break it down into what makes sense for your game

#

having a bunch of components on 1 object is not going to be any worse then 1 massive component

#

and will be easier to manage and share some of its features with other objects as componetns

#

also composition does not always mean you need new components

#

having regular C# classes you use in multiple places does the same job if they dont need all the extra stuff a true monobehaviour gives

latent latch
#

I'd argue you'd probably want to have a service locator and not search by (linear) component search, and keep gameobjects you want to interact with on their own specific layers.

#

meaning there would be some type of grouping via interface or class

#

i.e. An IEntity interface where you know this object has health, some methods that involve interacting.

spring creek
sudden stump
#

I'm aware that this exists, but would having 30 monobehavior scripts affect performance compared to one big script if all of them don't have update()?

#

Someone a while ago told me this does affect performance, and now someone's telling me the performance is negligible at best

spring creek
#

I mean, EVERYTHING affects performance. So I think negligable is a good word for it

#

"Affect" is just a bit vague. It wouldn't overtly harm performance

sudden stump
#

I mean, it's not like I'm going to have a lot of high poly models so all I have to worry about is code performance

quaint rock
#

or worry about getting the game done

#

would worry about making your code do what its supposed to do and be easy to read before performance

#

if performance is a issue you can profile things and find out where and why

#

instead of jumping at any and everything

spring creek
#

It always depends. So just try things and profile.

heady iris
#

again, this is not a performance problem

#

this is a game design problem

#

I didn't rewrite my game from near-scratch because it was running too slowly

#

I did it because I couldn't express my creative vision (ow that hurt to wrote)

#

i couldn't make the thing i wanted

#

there we go

quaint rock
#

also 15 years of dev, in my experience what people think will be a perf problem is often not, and osmetimes they create a worse problem working around it

#

weather that be a new perf problem or just making it hard to maintain the codebase

#

seen that on both the art and code side

#

had artists cause fillrate issues by over optimizing for triangle count

latent latch
#

and this would be more of a mem problem than runtime performance which you're less likely to run into

#

which is miniscule at most, your loaded textures and models will contribute the majority of what's loaded into mem

How can I override the sort order of an overlay canvas to be below the sort order of another canvas tied to a camera?

latent latch
#

sounds like rendering ordering of the cameras

little meadow
#

I don't think that you can

#

overlay is overlay

heady iris
#

Overlay cameras draw on top of everything else

#

they draw after the camera is done rendering

#

so, you can't

little meadow
#

if you wanna do some hacks, there might be some options... but it'd be more preferable to adjust approach

heady iris
#

What're you trying to make your UI do?

hexed oak
#

I have a UI piece on a canvas that I want to display independent of a camera--so it can display regardless of the current active camera.

#

However, there is a certain case where I want it to be hidden by another stacked camera's rendering

little meadow
#

display it on another always active camera

hexed oak
#

I was holding off trying that solution, though it may work. I'd have to juggle some cameras

little meadow
#

you can probably render some camera to a render texture and then display that on the other with the desired order, but that sounds like more of a workaround

latent latch
#

Are these not two overlay canvas? I would assume you can get by with the ordering on the stacking interface

merry stream
#

can anyone give me some input on making an ability system like this https://gdl.space/qurecuhuke.cs ? This is what I have so far. I want to know if it's worth continuing down this path or would it be better to just code each ability on it's own. I am making an ARPG similar to POE and Diablo and need to have interacting effects such as burning, poison, speed buffs/debuffs, etc

heady iris
#

That's roughly how I've done effects in the past

hexed oak
heady iris
#

I'm unsure about Apply needing to know about a caster, though

hexed oak
#

I think I'm going to have a script that disables the overlay canvases in this particular case

heady iris
#

It makes sense for an ability to have a caster

#

But effects shouldn't demand a caster

#

although, maybe I'm just interpreting "Effect" too broadly

#

that makes me think of basically anything that can happen to something

merry stream
#

yes it is, like SpawnProjectileEffect

#

the projectile needs the owner to know what targets are "allies"

#

for example

#

the issue im running into is passing stats into a system like this

#

and modifying the values of the effects at runtime

latent latch
#

one huge issue I have with ability systems is targeting

#

and trying to keep abilities reusuable

heady iris
#

I'd make the effect just define how to calculate the damage

#

actually, here, this might be relevant to you

#

i made a very elaborate system for a soulslike a while back

merry stream
#

im basically trying to make a very simplified version of GAS in unreal

latent latch
#

as always, I like to pass IEntity around everywhere which includes stats too

heady iris
#

i made all of my stats into scriptable objects, so entities aren't even guaranteed to have all of the kinds of stats

image.png
#

you could replace those with enums

merry stream
#

my stats are already enums

#

and all the stats on my items get summed on my character

heady iris
#

a weapon deals base damage, plus scaling based on your stats

merry stream
#

yep

latent latch
#

well, there's two ways you can do stats

merry stream
#

im doing it slightly different where the item is defined by affixes like poe

latent latch
#

cache the calcs, or do it all on hit

merry stream
#

im doing it all on hit right now, maybe a bad idea?

latent latch
#

or go mid-way and try to cache as much as possible

merry stream
#

for damage

#

for example, i want the damage to change if the stats end up changing

latent latch
#

poe cache's a lot of their stuff (and it still sucks because that game drops frames like crazy)

merry stream
#

like if theres a poison on an enemy and i get a poison boost, the posion should increase

#

therefore it needs to know about the caster

merry stream
latent latch
merry stream
#

should I just not do that? its not really neccessary i guess

latent latch
#

snapshotting sources, vs updating sources

merry stream
#

it could just snapshot

#

yes

#

now that I think about it, i think most arpgs just snapshot

heady iris
#

That's also what I would expect to happen

#

on hit, mash all of your stats together and spit out a number

latent latch
#

snapshot is easier too, so I'd go with that

merry stream
#

that's what I do right now with a very basic attack system, no abilities yet

#

just shoots projectiles that crunch the numbers and apply damage

#

but with this system I can't figure out how to easily pass the "damage" "increase effect" etc around

#

and make it generic at that

little meadow
#

In the last dev talk the Diablo people explained that they're trying to go away from snapshotting, because it allows people abusing systems to gain effects for longer than intended (of course, that's specific to some skill types and combos)
