Good old “turning it off and on”, yes

Position is a vector entity but it only represents a point. Vector in general means direction

meager siren
#

im trying to replicate this but for position

and or vector

meager siren
#

wait I think I just figured it out

#

nope

#

im a dumbass

I don't know where the code is wrong but I don't have the "on collect effect" part like in the tutorial

why is it ide, i remember doing it?

hot wadi
#

Lol it’s still not properly configured

#

Clearly something is missing

#

No wonder the vs code did not show up

#

The option is VS Code, don’t mistake it with Visual Studio

Hi guys. Since I couldn't find shader channel, I ll post it here. Is it possible to do 2022.3.62f1 URP shader that occludes everything behind a plane except skybox? I never did shaders and forums & otherwise havent helped much.... Found some which made ghosting, so the skybox would make artifacts...

#

Or really any other way to hide something from both sides, so its not visible in either direction behind a plane. Does not have to be a shader.

timber tide
#

wouldn't everything behind a plane occlude anyway

#

or is this like some seethrough plane mask you mean that unrenders things behind it

long scarab
#

Transparent plane

#

so skybox is visible

#

Apologies for not specifying

timber tide
#

Only objects behind it?

long scarab
#

Yes

#

Yeah the use case is basically for a mod to a game where two side spawns shouldnt see each other for first X time.

#

so I thought about adding two planes in between and occluding everything but skybox/terrain etc

queen holly
#

im new to unity but i cant find out how to makea door. I have watched a few videos and none of them have seemed to work, would anyone be able to help?

long scarab
#

but the othe side needs to see the objects near them

#

hence why it must be invisible just for one side

#

and vice versa

timber tide
#

This discord server* doesn't really like to discuss modding unless specifically about your project, but you'll probably want to look into stencils and using this transparent plane to update the stencil buffer

long scarab
#

Doesnt stencil mean the materials on all the objs must be also adjusted?

timber tide
#

it means all objects you want to cull must be a buffer value of +1 (where 0 is default)

#

meaning the plane updates the buffer from 0 to 1

#

plane must be in opaque queue too

long scarab
#

Okay-ish 😄

#

I ll try to investigate thanks

#

Albeit also never using stencils 😄

timber tide
#

rather the objects should be 0, if you made them 1 then it would be a reveal shader, but rather you increment it to 1 from the plane meaning all further pixels behind must be 1 or they wont render. I forget if this causes problems with the skybox though hmm

#

alternativley you can just write to depth but not draw... but I think this wouldn't draw the skybox either

#

if the stencil idea doesnt draw the skybox it means you should render the skybox twice for both buffer value 1 and 0

#

anyway, complicated stuff

long scarab
long scarab
#

it would take me ages to do probably 😄

timber tide
#

I mean, stencils are more difficult in concept

#

you have the tools already available

long scarab
#

Well, thank you for pointing me in the right direction!

kindred dome
#

if ive got a script that says

private Renderer renderer = null;

void Start()
{
    renderer = GetComponent<Renderer>();  
}``` does it matter if i leave renderer unassigned or assign it null?
#

im guessing it probably doesnt matter

timber tide
#

that's fine

#

I would use awake though for when you're doing initial component referencing

InputActionMap with path 'UI' in asset "" could not be found. The Input System's runtime UI integration relies on certain required input action definitions, some of which are missing. This means some runtime UI input may not work correctly. See Input System Manual - UI Support for guidance on required actions for UI integration or see how to revert to defaults.

how to add UI to actionmap fast?

Hey, Im starting to learn coding in unity and I was wonderign about this sample code:
Is tooltip a custom function, or a comment? It has information that would be more helpful for a programmer than a user, but i thought comments were made with //.

image.png
sour fulcrum
#

tooltips show up when you mouse over those fields in the inspector

#

so it's kind of like an engine comment yeah

light star
sour fulcrum
#

Both! It's a function defined in another script built into unity 😛

The syntax of [SomethingRather] above a class, function, field etc. is called an Attribute, It's a C# feature Unity uses in a couple places

#

In this case, When you select your WeaponController instance in the editor, when Unity runs its code to show you it's current values in the inspector it will look for those kinds of attributes and if they exist, use that data to best render those values for you

polar acorn
light star
#

alr, thank you !

#

Is there an easy way to check in my project, where a variable is referenced?

sour fulcrum
#

In visual studio you can right click the variable name and click find references

fiery canopy
#

If it is a property, there is a small text that says references above it too

grand snow
#

(if this feature is enabled in visual studio)

#

Most IDEs have a way to find references of some variable or type

light star
sour fulcrum
#

Well it doesn't search your Unity project because we're talking about a variable, It just looks through all your project's scripts

Can someone help me? Why don't these red images scale properly with their parent object when I change the viewport size?

From my understand, I'm using the Vertical Layout Group and Content Size Fitter properly

#

Doing that stretches them all the way to the edges

image.png
#

I just want them to be in the center

grand snow
#

what do you actually want them to do 😆

#

you need to describe it better in some way

wispy bison
#

To look like this

image.png
#

At all viewport sizes

#

And when I add more, they'll stay in the center

grand snow
#

thats too vague

#

how are the anchors set for the white box parent?

#

If you want padding on the left and right of the red elements then set the padding values on the layout group

wispy bison
#

The anshors on the parents are just at the edges

image.png
grand snow
#

That means the white box and thus the red elements will resize width and height as the screen changes size

wispy bison
#

So I added the padding which helps with the horizontal space, but the vertical space gets weird at some sizes. And if I check "control child size" the boxes just disappear

image.png
grand snow
#

when control width/height is OFF then the width and height set on each child rect transform is used

#

otherwise when control is enabled it will force expand width/height if enabled OR use settings from a layout element component

wispy bison
#

Thank you, I'll look into this layout element component

grand snow
wispy bison
#

I'm just having a hard time because every UI element I make scales correctly except these red boxes

#

Every time I change my window size, they change size

#

Only solution I can think of is to switch to a specific resolution

image.png
grand snow
#

Its just because you miss understand whats happening rn. The parents anchors make the parent size change but the layout group children by default will just keep their width and height defined on their rect transforms

#

you can enable child width/height control and disable force expand so it will downsize when they would "stick out"

#

you can play around with it all in editor to see

guys when i start the game it makes me facing right even if i am mooving left this the code

void animationState()
{
if (movement.magnitude > 0.1f || movement.magnitude < -0.1f)
{
mooving = true;
}
else
{
mooving = false;
}
if (mooving)
{
anim.SetFloat("X", movement.x);
anim.SetFloat("Y", movement.y);
}
anim.SetBool("Moving", mooving);

if(movement.x < 0 && isFacingRight)
{
    transform.localScale = new Vector3(-1, transform.localScale.y, transform.localScale.z);
    isFacingRight = !isFacingRight;
}
else if(movement.x > 0 && !isFacingRight)
{
    transform.localScale = new Vector3(1, transform.localScale.y , transform.localScale.z);
    isFacingRight = !isFacingRight;
}

if(movement.y > 0 && !isFacingUp)
{
    swordSP.sortingOrder = 0;
    isFacingUp = !isFacingUp;
}
else if (movement.y < 0 && isFacingUp)
{
    swordSP.sortingOrder = 2;
    isFacingUp = !isFacingUp;
}

Yea, seemed like I was doing everything wrong, but once I found this setting it just works

#

Not sure why it's not on by default, my god

earnest patio
#

idk why unity is yelling at me about object reference not set an instance of object.

for my player i have:

public static playerMovement instance;
//Update to player branch
private void Awake()
{
    origSize = transform.localScale;
    body = GetComponent<Rigidbody2D>();
    boxCollider = GetComponent<BoxCollider2D>();

    if (instance != null && instance != this)
    {
        Destroy(gameObject);
    }
    else 
    { 
        instance = this;
    }
}

for my enemy base class i have:

protected virtual void Awake()
{
    rb = GetComponent<Rigidbody2D>();
    player = playerMovement.instance;
}

for my lizard enemy i have:

protected override void Update()
{
    base.Update();
    if (!isRecoiling)
    {
        transform.position = Vector2.MoveTowards(transform.position, new Vector2(player.transform.position.x, player.transform.position.y), speed * Time.deltaTime);
    }
}
#

so like the player is a singleton, why is it not letting me access it

#

enemy base is mono behaviour, player is too. lizard inherits from enemy base

sour fulcrum
#

enemy awake probably is running before player awake

earnest patio
#

how would i fix that?

tight oak
#

Stupidly simple question I'm just having a hard time finding the documentation for the UI Toolkit and style-sheets: how would I go about making my button-hover scale ONLY on the x axis? Like when I hover the mouse over it the button gets wider?

image.png
sour fulcrum
tight oak
#

Oops- thank you! I shall scoot over there sadok

sour fulcrum
# earnest patio how would i fix that?

could move from awake to start
could manually make player earlier than everything else in Project Settings => Script Execution Order
could reference the singleton directly instead of caching it

earnest patio
#

could you help me with the 3rd option

#

how would i go about referencing it directly

#

not exactlhy sure what caching it means here

sour fulcrum
#

(you already do that when you cache it in awake)

#

caching is saving the reference for later so you don't have to do the work every time (if there is work to be done)

earnest patio
#

oh so i could just use playerMovement directly

#

still giving me an error

#

i honstly dont know how i got this error. what i did worked perfectly some time ago

earnest patio
#

can anyone help me with my player, base enemy, and enemy code? i cant seem to get my enemy to reference my player despite the player being declared as a singleton

where does unity load that list of dlls from when you try to add a precompiled reference to an assembly definition file?

Could maybe run a project wide search in vs code or something

languid pagoda
teal viper
languid pagoda
#

where does unity build the asmdefs out to any clue?

#

i bet i can find them there

teal viper
#

The player and editor ones are probably in the library somewhere

#

Searching for one of the names in vs code or similar text editor tool, might find you a file that has the mapping of name to path.

#

But it could also be working on the basis of include paths, so the editor searches through the include paths for these names and doesn't have an explicit mapping anywhere. This is very common in build systems.

#

In Godot, Search Help and documentation was amazing. I could just look up what I wanted to do and it would explain clearly what something does, all the properties, functions, etc.

In Unity, I'm meant to use the Unity Documentation Website the same way, right? (and, is there a dark mode version?)

every error keeps happening

astral void
#

Hey y'all, I'm trying to make my variable set privately in only the same class but gettable in any class. so I thought solution would be to make a property? but it doesn't seem to work. here is an example.

 public Bounds TestArea { get; private set; }
    private void TestFunction()
    {
        TestArea.center = new Vector3(4, 0, 0);
    }

I would like to edit the value of TestArea.center, but I cannot.
I have looked at the error message.
"Cannot modify the return value of 'GridManager.TestArea' because it is not a variable"
It seems odd but I guess I cannot change TestArea in parts (like one field in it), only all at once.
Here I have an alternative that seems to work to avoid this issue

 public Bounds TestArea { get; private set; }
    private void TestFunction()
    {
        Bounds newArea = TestArea;
        newArea.center = new Vector3(4, 0, 0);
        TestArea = newArea;
    }

but I'm not a fan. I think I've found a solution to the issue but it feels messy and unnecessary. Is there something that just lets the first example work? or a nicer solution? I'm very new to properties so there's a lot I'm probably missing. I would just like advice or any suggestions of how to do this differently if possible.

I am aware of the alternative of making a private field and then getter methods to get them in other classes, but this is my attempt at an alternative to that because I don't like it much :p feels even messier tbh

You just modify testArea in the script and other scripts get the value through TestArea

i have a problem

#

in this video are a lot of bugs

#

like there are 4 UI components one for health, one for the time one for cooldown fo the dash abilty and one of the score being the number of enemy killed

#

then the enemies, their bullets dont work as expected

#

then the buttons i have a button animation that when applied makes the button bigger than wanted

#

in other words this has a load of bugs

#

should i restart from zero or is this still savable ?

its important to learn how to salvage a project you think is broken

so how can i salvage it, its a burning pile of trash that if i change a singular line of script the whole game breaks

A tool for sharing your source code with the world!

knotty river
#

but as a you can hear when the bullet spawns it stays in the enemy

eager spindle
# knotty river it doesnt fully get out

When you spawn a bullet, I assume you're setting the velocity of the bullet to enemy's position minus the player's position. The concept is right, but you also need to consider that the enemy is moving.

Think of it this way; when you're running and throw a ball, the ball's speed = the speed you're running at + the speed that you throw the ball.

You need to set the bullet's velocity to the speed of the enemy + the speed of the bullet.

hey i'm having a bit of a struggle with the unity input system: when unity reloads scripts at runtime it obviously resets all the references set in awake my question is: do i have to set the references that i set in Awake in OnEnable again - since something inside me tells me that this can't be how its being done - even tough it does work then. (and please ignore the unused method) https://pastebin.com/xEK9MSh3

make sure you only have one Instance

#

also you are assigning the object 2 times, in Awake and OnEnable

tired junco
#

but isn't that the case here - only having one instance

frail hawk

it is, but you are not checking if Instance is null, otherwise you are overriding it

ur right but this did not rly answer my question - do i need to reset it when unity recompiles the scripts

How to Set Input

To set Active Input Handling, go to:
Project Settings > Player > Active Input Handling

• Input Manager (Old): Use the original Input settings.
• Input System Package (New): Uses the new input system package.
• Both: Use both systems.

you are using the Input class which is for the OLD input manager

hello i have this script here and it's very simple. it should on collision destroy the gameobject it collided with, if its called "player"

i have a collider on both the sphere and the "player" being collided

#

and the sphere has a rigibody

#

i launch the game and it when it collides nothing happens. no logs no nothing even

did you assign the Tag to the Player

do you have cooliders on both objects and at least one rigidbody

And I'll jump ahead a bit here - you can't do Input.GetKeyDown in FixedUpdate either 😛

    }
}```
wintry quarry
#

You need:

public class buttonScript : MonoBehaviour, IDragHandler```
#

(P.S., the convention for class names is PascalCase, so ButtonScript)

#

Also there aren't really any delegates in this code

ivory bobcat
# vast talon player moves, the camera doesnt.

So just for clarity, the camera's x and y values are properly updating whereas you've got its z value set to zero. The camera should be following the player relative to x and y unless... you're moving sometime else.

vast talon
#

The player moves perfectly

#

I checked its transform its fine

#

The camera dont move

#

At all

#

I think my codes autistic

ivory bobcat
ivory bobcat
# vast talon The camera dont move

The object is moving according to the logs. Concern would be if it's your actual camera. Another concern would be if you've got constraints with the camera.

tired python
wintry quarry
tired python
sour fulcrum
#

(You also might be combining the terms event,delegate and the concept of events together)

wintry quarry
tired python
wintry quarry
#

The only thing special about an event is that it can only be invoked by the class that declared it

#

otherwise it's identical to all other delegates

#

there are no special rules about how it is called

tired python
#

oh wait

wintry quarry
#

some code must simply invoke it

tired python
#

so like....a is basically a list which holds functions and when you call a, you call all the functions present inside a

wintry quarry
#

yeah, sort of

tired python
#

what's Action type?

#

or is it a data type

wintry quarry
#

just a delegate type - it means a function that returns void and has no parameters

tired python
#

or a modifier

wintry quarry
#

delegate types describe the "shape" of the functions that can fit in the variable

#

Action is any function with void return type and no parameters.
So:

void Hello() {}```is an action but:
```cs
int Blah() { return 5; }``` is not
#

You can also do like Action<int> which would be any function that returns void and has a single int parameter'

#

e.g.

void Goober(int x) { print(x); }``` that would fit in `Action<int>`
tired python
#

aight, another question, how do you begin to decipher this? as in, for you guys, looking at this makes you understand exactly how you can use it, to me, it just seems to be unrelated stuff.

image.png image.png
grand snow
sour fulcrum
#

So first of all, the second screenshot is called an Interface, hence the naming convention of it starting with I

#

Are you familiar/comfortable with inheritance currently?

tired python
#

as in, you can only inherit one type, but you can inherit multiple interfaces

sour fulcrum
#

ok so you get how inheritence works with normal classes then

tired python
#

you can inherit the parent class's methods and stuff

sour fulcrum
#

interfaces are like a primitive version of inheritance where the Interface defines what the deriving thing will have, like a promise

#

then when some code has a reference to the interface (eg. IDragHandler), it can call those promised functions knowing whatever the interface actually is has some implementation of those promises

#

Interfaces exist because very different things can share similar behavior

#

here's a cursed example

# 
public interface IPromiseToKillMyselfOnRequest
{
    public void Die();
}

public class Car : IPromiseToKillMyselfOnRequest
{
    public void Die()
    {
        Explode();
    }

    private void Explode()
    {

    }
}

public class Human : IPromiseToKillMyselfOnRequest
{
    public void Die()
    {
        HaveHeartAttack();
    }

    private void HaveHeartAttack()
    {

    }
}
#

a Car and a Human are very different things, but both share the idea that they could "Die" in some shape or form

#

they have very different interpretations of what that means, as you can see

tired python
#

demn, it turned rly morbid all of a sudden

sour fulcrum
#

i've been up awhile forgive me

#

anyway, going off that

#

lets say we have this

public class WorldManager
{
    public List<IPromiseToKillMyselfOnRequest> AllKillables = new List<IPromiseToKillMyselfOnRequest>();

    public void KillEverything()
    {
        foreach (IPromiseToKillMyselfOnRequest killable in AllKillables)
            killable.Die();
    }
}
#

this WorldManager does not need to know if something is a Human or a Car or whatever, that's not it's job to know

tired python
#

👀

#

aig-ehm....aight

sour fulcrum
#

but because of the promised Die() function in the interface, it can call that on all of them knowing that whatever has implemented that Interface, has provided some sort of answer for that function

#

so going back to your draghandler

unkempt tundra
#

hey i have a question if i have a big scene with many objects rendering in the scene. instead if i converted all the fbx files to stl and made a mesh reader and render all the object dynamically would that be better in term of memory or performance?

sour fulcrum
#

you would implement that interface (eg. class ButtonScript : MonoBehaviour, IDragHandler) and provide an answer to that promised function OnDrag() and whatever Unity has to manage the dragging systems will call that for you when it finds it

blissful stratus
wintry quarry
#

shadows don't render past that distance

tired python
wintry quarry
#

It will get called by the game engine when you are dragging things.

#

not as part of Update though

#

Maybe you mean "every frame"?

tired python
#

so for every frame that i am dragging, it gets calles right

sour fulcrum
#

Update() is completely unrelated to this.

Unity has some way of finding all the things that implement IDragHandler that currently exist and will iterate through them and call that function when relevant

wintry quarry
tired python
#

and it does so outside of the update()?

sour fulcrum
#

update or frame

tired python
#

for every frame that i am dragging

wintry quarry
#

you can see this in the profiler

sour fulcrum
#

At most I think every frame yeah, but as mentioned in that doc every time the cursor is moved so on frames where you haven't moved the cursor and are still dragging it won't fire

#

Worth pointing out just in case that the frequency of when the OnDrag function is based just on how that specific interface was implemented in Unity, nothing fundamentally with interfaces as a concept defines when they will be called

tired python
#

it's an actual mystery the fact that unity can call the correct stuff inside every update method available across all the scripts in the right order

sour fulcrum
#

Once you get more comfortable with Unity you'll be even more weirded out with how Update, Start, Awake work etc.

#

it's certainly not standard / "good" practice

#

Also there is no "right" order btw, it just depends on how your code is setup for if it will or will not be affected by a "bad" order

glad dagger
#

i finished my double jump mechanic but when i double jump and then go a bit down i can double jump again what should i do to fix it

  private void Update()
  {

#

presumably you tried to save data to a project id or player id that you don't have permissions for

#

or maybe the access token itself is bad

timber mesa
#

Could it have something to do with the fact that I'm testing it in play mode? So I'm signing in anonymously and could not have a player id?

#

Because the function is on CloudCode, it should have access to everything

wintry quarry
#

Now would be a good time to start debugging

#

print your access token, project id, and player id

timber mesa
#

all are not-null

wintry quarry
#

are they even nullable types? It's not about if they're null

#

it's if they're valid and sensical

timber mesa
#

Yeah they're valid, I probably shouldnt send a ss of them right?

wintry quarry
#

The server is clearly telling you that you're not authorized to do what you're trying to do

#

see if there is any other data in the exception

#

there should be a message

you're using accessToken

is there a way to call StartCoroutine in an abstract class? I'm seeing a lot of "no" and it ruins stuff ;-; basically I'm trying to run a function in a class that inherits from an abstract class, polymorphism stuff, and in that function i want to call a bunch of coroutines. I'm thinking I could switch to an interface instead of polymorphism and that might fix it but hoping for other solutions

wintry quarry
#

just note that StartCoroutine is a method on MonoBehaviour, so you, as always, need a reference to a MonoBehaviour instance to call it on

astral void
#

yes... but i get "An object reference is required for the non-static field, method, or property" error

# 
public abstract class ActionClass
{
    public abstract void Activate();
}

public class NewAction : ActionClass
{
    public override void Activate()
    {
        MonoBehaviour.StartCoroutine(MatchManager.instance.ChangePhaseVisualRpc("phaseName"));
    }
}

example code, error here

wintry quarry
astral void
#

oh I read your message wrong oops

wintry quarry
#

you need an actual instance to call it on

astral void
#

yeah...

wintry quarry
#

it's not a static method

#

StartCoroutine(MatchManager.instance.ChangePhaseVisualRpc("phaseName"));
This is a code smell

#

is there a reason you don't just start the coroutine right there?

#

MatchManager.instance.StartChangingPhase("phaseName"):

astral void
#

because i want to yield return it (forgot to put that in oops)

wintry quarry
#

then on MatchManager:

public void StartChangingPhase(string phase) {
  StartCoroutine(ChangePhaseVisualRpc(phase));
}```
#

no, look

#

this is how you should do it^

#

and call this

#

MatchManager.instance.StartChangingPhase("phaseName");

astral void
#

I want to run a few coroutines and have them happen in order, I don't know how to do that with your method

wintry quarry
#

I just showed you

#

Use the MatchManager instance to run the coroutines

astral void
#

ok lemme edit it to better show what I mean

wintry quarry
#

MatchManager is a MonoBehaviour, right?

wintry quarry
#

just FYI

astral void
# 
public abstract class ActionClass
{
    public abstract IEnumerator Activate();
}

public class NewAction : ActionClass
{
    public override IEnumerator Activate()
    {
        yield return StartCoroutine(FirstRoutine());
        yield return StartCoroutine(SecondRoutine());
        yield return StartCoroutine(ThirdRoutine());
        //function that called Activate will now continue their own code since this has finished
    }
}

this is more what I'm trying to do, I hope it's clear enough-

astral void
wintry quarry
#

Yes it's very clear, but you need a MonoBehaviour to run coroutines

astral void
#

ok yes yes

#

got that

wintry quarry
#

So - you need to create a dedicated monobehaviour for running the coroutines

#

and run them on that component

#

That could be your MatchManager if you want

#

or some other singleton

astral void
#

A big part of the ActionClass though is that it is called from MatchManager and then MatchManager waits for the coroutines to end... not sure how to make the code wait for the functions to end in that case... is there a way to pause a function like that?

wintry quarry
astral void
#

oh yes sorry

wintry quarry
#

then you have no problem

#

You start the coroutines from MatchManager

astral void
#

but I need to know when the coroutines are finished-

wintry quarry
#

you use a coroutine

#

show me an example of how and when you call Activate

astral void
# 
 private IEnumerator ChangeAction()
    {
        yield return StartCoroutine(ActionOrder[CurrentActionIndex].Activate(new PhaseActionParams()));
        CurrentActionIndex++;
        CurrentActionIndex %= ActionOrder.Count;
    }

the code is incomplete and I plan to change this, but currently this is what I have

#

this is in MatchManager

wintry quarry
#

Ok so looks like you're already doing it in a coroutine

#

so there should be no issue

#

but Activate certainly needs to return IEnumerator for this to work

#

not void

wintry quarry
astral void
#

yeah like that

#

wait

wintry quarry
#

Instead of:

yield return StartCoroutine(FirstRoutine());```
You can just do:
```cs
yield return FirstRoutine();```
#

it works the same

astral void
#

so it won't move then until the coroutines in MatchManager is done?

wintry quarry
#

that's what yield return does

astral void
#

oh i didn't know that

wintry quarry
#

if you really needed to call StartCoroutine, you can always do MatchManager.Instance.StartCoroutine(...);

#

but it's not needed here

2 questions. 1. is this efficient? 2. How would I be able to discern an actual string and a JSON serialized string?

#

Ok let me ask a different question actually, now that I read this a little

#

Why are you not sure if the data you're getting back is a json string or... something else?

#

are you expecting both things to come back?

timber mesa
#

Because CloudSave will serialize all objects on save, when getting, if the value can be deserialized into a .NET object, it will auto do that, otherwise it stays as a JSON serialized string

wintry quarry
#

Why would the value ever not be able to be deserialized

#

If it's not able to deserialize it, you can probably just give up, and spit out an error, no?

#

Presumably you should know the actual data type you expect to come back you call this I would think

timber mesa
#

Well if I ever had like a custom class/type that I wanted to be saved, it would be JSON serialized on save, but would not be auto deserialized on get

wintry quarry
#

would you ever be saving a raw string that wasn't json?

timber mesa
#

I mean, currently idk, I'm just still setting up the foundation before I dig into actual player data

#

I would like the option to be available if it ever arose. Maybe like DisplayName, that could be a string

wintry quarry
#

For any given key, you will know ahead of time the type of data or will be

#

It's a non issue

timber mesa
#

true, maybe I can just have the Function deal with deserializing and return object, so when saving back it will just serialize

wintry quarry
#

I kinda hate that the api is trying to serialize/deserialize for you

timber mesa
#

Well it has to serialize from what I understand, like you cant just store actual objects. It's like compression.
I did however change my code

# 
public static async Task ModifyPlayerData<T>(
        IExecutionContext context,
        IGameApiClient gameApiClient,
        string key,
        Func<T?, dynamic> modifier
    ) {
        await ModifyPlayerData<T>(context, gameApiClient, key, modifier, false);
    }

    public static async Task ModifyPlayerData<T>(
        IExecutionContext context,
        IGameApiClient gameApiClient,
        string key,
        Func<T?, dynamic> modifier,
        bool deserialize
    ) {
        string playerId = context.PlayerId!;
        try {
            T? currentData = await GetPlayerData<T>(context, gameApiClient, key, deserialize);
            
            var newData = modifier(currentData);

I think I've seen you here for a few days now. You might want to provide the screenshots that you've last had or a link to the latest discoveries. Last I recall, your coordinates were being updated (although extremely high in value) but supposedly the object (camera) wasn't moving. Either it's referring to a different object (main camera etc) or you've got some constraint that prohibits the camera from moving (physics constraint, Character Controller component, code or something other)

You could quickly verify by clicking on a cloned object in the hierarchy and checking it's position, rotation etc

frail hawk

exactly

#

you need to learn debug techniques and analysing problems, this will save you alot of headache

Were those values acceptable? (note that they're all low and negative values)

tired python

why would they show up the right way on the scene but not the right way in game

ivory bobcat
tired python
tired python
#

wait then why does it show up in scene O_O

#

i don't understand, if its below the cavas, it shouldn't show it

ivory bobcat
#

The scene view isn't necessary from the camera's view.

#

Either way, check those values and see if they're acceptable

frail hawk
#

i am assuming something is wrong with your camera, did you change any settings there

tired python
#

ignore the mousescript, it's what i was using before to do this

ivory bobcat
# tired python

Show us the inspector and components of the visible droplet. How does it differ from those not visible?

tired python
ivory bobcat
ivory bobcat

#

i am sorry if it takes me sometime to upload images, my pc is pretty 🥔

ivory bobcat
#

So manually try changing the z value for a non visible cloned object and see if it becomes visible.

tired python
#

this is my mouse position's z component

image.png
#

ya well, it becomes visible

#

my mouse position's z component is under the whole thing probably

ivory bobcat
#

So maybe you ought to edit that value before using it to instantiate your clones or use a edited vector 3 copy of position etc

tired python
ivory bobcat
#

You do understand that converting mouse pointer from screen to world disregards the z component

tired python
#

i need a fix for it...

frail hawk
#

if you really want to use it you need to give it a z value manually

ivory bobcat
#

I tried, good luck.

tired python
frail hawk
#

but i see that as a work around and i woudl not recomend it. instead fix the sorting layers etc

ivory bobcat
tired python
#

so i should just hardcode it then?

ivory bobcat
ivory bobcat
tired python
ivory bobcat

just for clarification, when would you consider hardcoding something to not be a malpractice

may i ask why you are using ui lement to drag and drop but then instantiate a sprite

ivory bobcat
tired python
frail hawk
#

but you can do that with ui lements too

tired python
#

but it's not ui, as in, the object instantiated ain't a part of ui right

#

could you clarify or elaborate what you are trying to say?

frail hawk
#

you can use animations on ui elements too

tired python
#

is a tower considered ui O_O

#

or is ui basically any interactable object on screen

frail hawk
#

good question.

what's the answer O_O

i´d probably use a sprite

why are you getting the world coordinates

#

is this a world-space canvas?

tired python
#

i know world space means the scene coordinate system, whereas local space is the relative position of an object to another object, so...local space uses an object as its origin

naive pawn
#

there is another

tired python
#

O_o

naive pawn
#

two more, actually.
there's screen space and viewport space too, which are both relative to the plane of the screen
one is in pixels and the other is normalized, i don't remember which, probably screen space in pixels

#

what mode is the canvas set to?

#

you should be able to choose between screenspace overlay/camera and worldspace

tired python
naive pawn
#

is it scaled?

tired python
#

if so, then ya..?

naive pawn
#

in the transform, shouldve been more specific

tired python
#

it's the original

#

i didn't tamper with it...

naive pawn
#

alright, so that all checks out (though tbh, having it as a non-UI object would probably be easier, and then you could keep the canvas in screenspace)

#

have you checked the position of that preview image at runtime at all

tired python
naive pawn
#

this stuff shows up in the inspector, not the hierarchy

#

select the preview image, look at its position, see if that changes as expected when you move stuff

#

if it does, it might just be layered incorrectly

#

Lets say I made a simple little error when initially setting up my project and might have created a 2D project instead of a 3D project. Is it possible to convert it somehow?

naive pawn
#

it basically just affects the default packages installed and the default scene template/scene view setup

#

if you change all of them to how they'd be in 3d (installing the 3d feature, removing the 2d feature, etc) you could "convert" it

#

but it's not really anything intrinsic to the project

rapid spruce
#

Yeah makes sense, I noticed that e.g. its using a 2d renderer etc.

#

if you aren't super familiar with unity yet and you haven't done much work, it'd probably be easier to just make a new 3d project and copy your work over

you're modifying props of the prefab, not an actual gameobject in the scene

so.. why didn't you figure out that it wasn't showing up in the scene because it's not in the scene

that's pretty straightforward

that's not really what i was asking

tired python
#

then i prolly misunderstood

naive pawn
#

the hierarchy is the list of things in the scene

#

if it's not there, it's not in the scene

tired python
#

so what do i do then...create a empty object, attach a script to it, which references this prefab and then reference that script ?

naive pawn
#

no, you don't need to reference the prefab at all

#

you aren't instantiating it at runtime

tired python
#

oh wait a sec then

#

prefabs are gameobjects turned into assets, that can be referenced and reused
right now you need a gameobject actually in the scene

tired python
#

ayo what

#

i copied it, and it doesn't show up O_O

naive pawn
#

you didn't put it in the canvas

ivory bobcat
#

Rect Transform usually indicates that they are part of a canvas

tired python
#

oh ya, i do remember someone telling me to not just yank it outta the canvas

ivory bobcat
#

Order may matter btw

tired python
#

now that i can instantialise the droplet onto the screen, i wanna know how you guys would recommend me to pick and drag those objects...should i use rays or smth else

frail hawk
#

glad you were able to fix it

tired python
#

i also wanna know how you might go about erasing them cus the dragon in the corner, that's a gameobject with an animator component, what i wanna do is basically, if anyone wants to sell a deploye dobject, they should be able to pick it up, then drop it in front of the dragon and then the dragon animation plays and the object gets destroyed

#

oh rob i finally implemented what you told me to use

is it..?

tired python
naive pawn
#

oh, yeah, that's a mistake

#

spriterenderers aren't

#

the mistake is spriterenderer + canvas

#

it's either spriterenderer on its own, or canvas+image

#

but i did mention before, that having the preview and actual placed objects be non-ui objects would probably be easier tbh

#

just the UI things should be UI

tired python
naive pawn
#

im not basing it off of moving or not moving

grand snow
#

here we go again

naive pawn
#

i'm basing it off of what is actually UI

#

UI should be UI
nonUI should be nonUI

#

that's all im saying

tired python
#

is UI considered whatever you can click on

#

yes or no

naive pawn
#

no

grand snow
#

no

tired python
#

O_O

ivory bobcat
#

Anything interacting with the scene would probably not be ui.

grand snow
#

Look at any other game, you KNOW what is user interface and what is not

ivory bobcat
#

UI would be like data input, controller or whatnot

grand snow
#

pause menu? User interface
health text? user interface
unit on the ground? gameplay sprite/model

#

sometimes things mix but knowing when to use one solution over another is important

naive pawn
#

the things in red here are UI. the placement/range preview could be considered UI, but it'd be easier to treat it as not
