do you see this Image itemPreviewImage = itemPreview.GetComponent<Image>();

[copper jasper]

ye

[rich adder]

you are not using the Image from UnityEngine.UI

which is what you want

delete these

using JetBrains.Rider.Unity.Editor;
using Microsoft.Unity.VisualStudio.Editor;```

then put using UnityEngine.UI

[copper jasper]

OH

😭

Spent all that time for what

Well now I gotta get images from the Project folder thing

then set them to be the source texture

[rich adder]

put a field for it

no need to search the project folder

set it in the inspector / drag n drop

[copper jasper]

but then i gotta do that for each item

hotbar system

like these

great now itemPreviewImage.SourceTexture = itemImage;

Source texture has a red line

[rich adder]

where are you getting SourceTexture from

[copper jasper]

the image from earlier

u know the one that i couldnt disable

i can disable it now but thats all

[rich adder]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.UI.Image.html
where do you see such a property

sounds made up

[sage abyss]

Hey, guys. I want to rotate a gameobject depending on its velocity (in my case pointer delta), but it's really jaggy. Is there something I do wrong?

[rich adder]

you probably want https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.UI.Image.html#UnityEngine_UI_Image_sprite

I mean thats the property for it, It would work in theory.

[copper jasper]

i hope

do u think its gonna work

Sprite itemImage = (Sprite)Resources.Load("Assets/UI/Hotbar/itemPreviews/" + item.name + ".png");

I hope so

[rich adder]

no because the Load method has wrong path

[copper jasper]

UnityException: Load is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'InventoryHandler'.

😭

[rich adder]

also just make fields..

[rich adder]

you cannot call method in the field initializer.. you can only put a property at most

[copper jasper]

im so lost

[rich adder]

but again you should not do it this way at all

[rich adder]

well if you guess your way through it ofc

did you read the docs how Resources.Load works ?

[twin pivot]

its in update not fixed update i think

[copper jasper]

nope 😄

[rich adder]

how exactly do you plan on making something work if you don't even know how it works

[copper jasper]

well i thought it would have been pretty straight forward

just a simple load

[rich adder]

it is when you read the docs on how it works.

[copper jasper]

😭

[rich adder]

I mean..it even has examples.. you're doing yourself a disservice

https://docs.unity3d.com/ScriptReference/Resources.Load.html

[west garnet]

i dont know if this is the best way to do something but
im making a rpg game for fun and i got different npc with different tasks that they give u so u can get a key ( they all have different scripts )
in each task i thought the best way to make the final gate to open was to comapre if the player had all the bool active
my plan is to make some text on the screen saying something around "you got "amount" of keys" ( aka the bool that i have ) how could i do it?

[rich adder]

store the keys in a list then check if the list has the amount of keys you need

a bool per key sounds like a mess

[west garnet]

how would you approach it?

[rich adder]

the way I suggested lol

[west garnet]

how would i do if a player completes a task? addes a key to the list?

that actually sounds better

[rich adder]

unless you need specific keys then I would make the Key itself an object and use an index/enum to distinguish it

[west garnet]

nah its just 3 keys

randomly

[rich adder]

so if its just needs to be 3 keys and you dont care which one i which, and you just need the amount collected, then use a list ye

[west garnet]

should i make a keyhandler or smth script? just to check the keys and stuff?

[rich adder]

You could if you want, thats up to you

[west garnet]

thank you for the help

[twin pivot]

if you insist on using bools but this is also a terrible way of doing it

[SerializeField] private bool[] myBoolArray

for (int i = 0; i < myBoolArray.length; i++)
  {
    if (myBoolArray[i])
      {
        Debug.Log("+1 key")
      }
  }

[west garnet]

probably will do the list

it does sound better

and less complicated

but thank you!

[rich adder]

array is valid too but not sure what the point of that loop

[twin pivot]

so you can extend the array as much as u want

[rich adder]

wdym extend to array

arrays don't extend they are fixed in size, hence the .Length instead of .Count

[twin pivot]

yea but you can extend it in unity

[rich adder]

yeah but you're bound by the inspector to do that, and all is doing is myArray = new bool[newSize]

you still need to loop through all of them anyway to check if they are all true

[twin pivot]

🤷 personal preference ig

[rich adder]

kinda lol

[untold shore]

Hey, any input onto this? Thanks

[twin pivot]

theres a setting in rigid body to enable gravity + theres no code that rotates the GameObject

[untold shore]

Theres a character controller on the player, does that have one?

[twin pivot]

whered u get the code for this?

[untold shore]

Currently in tutorial hell, so tutorials on YouTube 😅 never worked on 3d unity before, I’m used to 2d

[grizzled crag]

well, if you're looking to get out of tutorial hell, I think it's best to have this sort of "end"

since it is a pretty comprehensive guide, you shouldn't have to look for any more tutorials, and rely on the documentation from there forward

[rich adder]

rely on the documentation isn't a negative..

[grizzled crag]

oh I mean, you will rely on the docs

rather than tutorials

[rich adder]

[grizzled crag]

I forgot a comma my bad 😭

[past yarrow]

Is there a way to write my if statement this way instead of the inverted version of it but without returning anything as here my return statement at the end of my method, it should be a List<Tile but in this if statement I just want to get outside of that if statement to not execute neighbours.Add(tiles....);

So return doesn't work, continue doesn't work, so I'm kinda loosing hope on using a safe guard statement in this case and have to go with the inverted if statement 😬

[brave robin]

if break, continue, or return isn't working for what you need, you can also try goto as a last resort

[rocky canyon]

goto: back to classic

[past yarrow]

Is it what would be practiced in "pro" environement ? Or will "proes" go with the inverted if ?

pro env / good practice

[brave robin]

goto is generally avoided by pros, but sometimes the cleanest flow is to jump over everything else and go to the end
And sometimes encasing everything in a bunch of IF cases to do that is uglier than just using a single goto

[past yarrow]

alright, could you gie an example of how a goto works because I never used one please

[rocky canyon]

what im reading is use it if: whenever it's the cleanest and most maintainable way to write something, which is uncommon

[brave robin]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/jump-statements
Goto is near the bottom

[rocky canyon]

im slow

[past yarrow]

Thanks 👍

[brave robin]

I generally will only use a goto when the destination code is near the end of the method, and I'm using it to jump past something in the fastest and cleanest way
I would never use it to jump backwards, that way lies madness

[rocky canyon]

i see it mentioned alot about "error handling"

[rocky canyon]

like this gem i found 😅

[brave robin]

... cast it into the volcano before it is too late

[eternal needle]

could you not just return neighbours right there? i dont really see what the problem here is, but goto is 100% not your solution here

you really just shouldnt be using it

[rocky canyon]

ive never seen it in the wild

[brave robin]

I've used it exactly once in my current project. The circumstances where its more readable do exist, its just pretty rare

[past yarrow]

Nope because I have multiple if statement where I need to do that trick, so that's why I went for the classical inverted if approach

[eternal needle]

then swap around your logic. why not just check if the value is 0 before any of this?

[rocky canyon]

^ very true..

[brave robin]

Or && the != 0 into the initial IF statement

[past yarrow]

that condition doesn't apply to all tiles, only the corner ones

[brave robin]

But yeah, I think starting off with != 0 is better

[eternal needle]

then yea include it in the first if statement where you want it

and make a method so you arent writing the exact same logic 10 times

[brave robin]

also, I think a lot of those IFs should be ELSE IFs

[past yarrow]

I'm not sure to understand 🤔

[eternal needle]

i guess first focus on the part Contrivance said here #💻┃code-beginner message
you can just add the logic to the outer if statement

making a method for this would just avoid rewriting the same code over and over, but its not required if thats the entire logic

[rocky canyon]

^ i was also going to mention that too but wasnt sure if it was appropriate

all those if statements make me think a switch might work well too

[past yarrow]

Done

[eternal needle]

also youve most definitely been told about the code command before

[past yarrow]

code command ?

[brave robin]

Switch needs compile time constants, which might not work here. I used to run into that issue all the time when I wanted to make a switch running off of vector2int coordinates

How you wrote the code in the screenshot was fine. I was just saying if you sent the code like this initially, its easier to show you what we mean since we can copy and edit it

Btw you can check if the value is 0 before checking its in the grid. It's a micro optimization but that means it wont check the grid everytime if it doesn't have to

[past yarrow]

My bad, I'm used to send screenshots because usually these questions get solved really quickly and don't need rewriting the code 😄

[past yarrow]

I think I can't because the != 0 is only for the corners, as I don't want when I click on a tile and it's a 0 it propagates to 0s that are on corner neighbours

[eternal needle]

I meant swap the order of the if statement so you check tile.Value and then check IsInGrid in the same line

Right now it'll check if its in the grid everytime, then check if the value is 0 if it was in the grid.
If you check if the value is 0 first, it has a chance to exit that if statement early without checking if its in the grid

[past yarrow]

Oh I see

[eternal needle]

I have no clue why but that site also keeps deleting all the code as I try to scroll on mobile lol. Hopefully it was clear though

[past yarrow]

Like this ? 🙂

[eternal needle]

Yea

[brave robin]

Also, is it possible for multiple IF statements to be true? If not, then you should be using ELSE IF for the extras

[eternal needle]

Its a micro optimization but it could matter in the future if one condition is an expensive operation

[past yarrow]

yes

Argh my code doesn't work, it should reveal those corners as they're non zeros but it doesn't 😬

Yellow = Where I pressed
Red = What it revealed

It should be like this (with the corners)

[brave robin]

Actually, a cleaner way to do this is to encase it in two FOR loops, one for x and one for y, and then do the IsInGrid check on the x and y coordinates you get from the loops

[past yarrow]

Let me try that

[brave robin]

x and y going from -1 to 1, and adding that to the coordinate you clicked on to get all possible 9 positions

and a check for when both are 0, in case you don't want to do anything when its the exact tile you clicked on

[past yarrow]

I want when I click on a tile with "0" to make it propagate to adjacent tiles but not on diagonales that are 0 and the edges of those 0 that are != 0 but not -1 and the diagonal should work too (I hope it makes sense 😄 )

[brave robin]

nested for loops can achieve that, it removes the need to specify every possible coordinate, and you can put the logic inside for whether to place a tile or not

[past yarrow]

wait, what should be the condition for i and j inside those loops ?

like i < ?

[rocky canyon]

ur grid dimensions right?

[past yarrow]

true

[brave robin]

i = -1; i =< 1; i++
same for j
Since you're adding these to the x and y of the coordinate to get the adjacent ones

[past yarrow]

Oh

[brave robin]

its why I'd call them x and y and not i and j, makes it more clear

[rocky canyon]

ah ya, i was thinkin of the actual grid generation

btw, what u making? minesweeper?

[past yarrow]

yes

[past yarrow]

This is the code of generation

I think I will go to sleep guys, I'm tired 😄 I hope you're here tomorrow 😛

[rocky canyon]

i tried that once. i got the grid and selection stuff coded out
but i couldn't do the math for filling in the numbers

[past yarrow]

filling the numbers is easy, you loop through each tile and you count how many mines are neighbour of that tile and you set the number of that tile to that value 🙂

Good night 👋

[sour fulcrum]

Nothing wrong with this but sometimes can be nice to move this logic into it’s own function since it’s kind of it’s owned isolated job. Eg

SpawnNewTile(Tile tilePrefab, Vector2Int index)

Also just another 2 cents that you can take or leave but imo that code is slightly more readable if you do the tile coords and color setting on the tile reference directly thats right there and not via the matrix index reference. (The fact the reference is right there and your not referencing that makes my brain assume the matrix must be pointing to something different)

Final random suggestion that’s more for longterm is having the matrix assignment + coords assignment as a seperate function, so in the future if you ever wanna modify a tile’s position you can use the same central function

Can the async scene load create memory leaks like default events? If you don't -= after += I mean.

So compare this:

            var asyncLoad = SceneManager.LoadSceneAsync(deserialisedModel.CurrentSceneName);

            asyncLoad.completed += _ =>
            {
                _gameStateServices.ForEach(service => service.ReadStateFromModel(deserialisedModel));
                asyncLoad.completed -= handler;
            };;

to the clunky unsubscription:

            var asyncLoad = SceneManager.LoadSceneAsync(deserialisedModel.CurrentSceneName);
            Action<AsyncOperation> handler = null;
            handler = _ =>
            {
                _gameStateServices.ForEach(service => service.ReadStateFromModel(deserialisedModel));
                asyncLoad.completed -= handler;
            };
            asyncLoad.completed += handler;

[wintry quarry]

The delegate will be GCed once the async operation is gced

You don't need to unsubscribe unless you're keeping a long running reference to the operation around.

Wdym by "vertically across my entire screen"?

[topaz mortar]

nvm, it's because my canvas scale was too small, dumb or outdated tutorial maybe

thx though

[topaz mortar]

How do I get my healthbars to show up like in League of Legends? They're so stable, don't jitter or move as camera is moving and perfectly follow the units.
I tried it like this healthbar.transform.position = _cam.WorldToScreenPoint(worldPos);
But it keeps moving as I move my camera, it dances left/right up/down a bit.

[naive pawn]

for healthbars like that they'd probably be world-space canvases

anyways the issue you're seeing is probably due to stuff being out of order - likely this positioning happening before the camera is positioned

[topaz mortar]

I tried world-space first but that was even worse, since the camera position constantly changes the angle

[naive pawn]

within each frame, the world stuff has to move first, then the camera (if it moves independantly), then stuff that relies on the camera view (like parallax or UI)

but with a world-space canvas you can just sidestep the entire "position is reliant on camera position"

[topaz mortar]

it's better in screen space, but it dances a bit as the camera moves

[naive pawn]

you'd have to apply billboarding i suppose?

[topaz mortar]

This is what I have now:

[topaz mortar]

hmm not sure what that is

lol it has sound from the lol stream I'm watching 😅

[naive pawn]

basically rotating it to point towards the camera at all times

(there might be a better more built-in solution for this, i'm not a ui guy 😅)

[topaz mortar]

yeah I tried that, it was much worse than this
according to Chat GPT LoL uses screen-space for healthbars

[naive pawn]

yeah that's just.. not something you can determine?

don't trust chatgpt for anything lmao

it's gonna tell you everything with confidence whether it's right or not

[topaz mortar]

quick google gives the same result though

[naive pawn]

well i suppose it technically isn't wrong, this one is definitely in screen space lol

[naive pawn]

is it from an interview from devs

if not it's probably a guess

you could achieve identical results with world space and screen space UI
in fact these terms might not even apply since league uses its own engine

[topaz mortar]

can't find a single tutorial on this stuff that actually works

[naive pawn]

are you trying to fix the original issue or do billboarding or what exactly?

[candid garden]

for persistent data through scenes, for things like the player's party data and unlocks for example, would a persistent scene or don't destroy on load be more ideal and easier to work with as the game grows?

[topaz mortar]

I'm trying to do billboarding now
transform.LookAt(_camTransform.position); is the result in the video
also tried transform.LookAt(_camTransform.position + transform.position); with both + and -, neither work properly

[ivory bobcat]

What's the issue?

Can you describe what's expected and what's happening instead?

[topaz mortar]

I'm trying to add healthbars that stay perfectly above their unit, regardless of camera position & angle
Similar to how league of legends does it

[sour fulcrum]

dontdestroyonload is a persistent scene so whatever you prefer tbh

[sour fulcrum]

you probably want your ui stuff on a screenspace canvas that sets its position to the converted world space

rather than the ui being in worldspace directly

[topaz mortar]

@sour fulcrum this is what I had before

[naive pawn]

@topaz mortar i did answer about why that was likely happening, if you missed that?
#💻┃code-beginner message

[topaz mortar]

alright let me start over again 😅

[naive pawn]

with perspective view this would point towards the center of the screen, whereas you'd want it to point perpendicular to the screen plane

[topaz mortar]

actually a lot better, still not perfect

This is what I have now: (Quantum, so different update function)

{
    Vector3 offset = new Vector3(0, 3f, 0);
    Vector3 worldPos = transform.position + offset;
    Vector3 screenPos = _cam.WorldToScreenPoint(worldPos);

    healthbar.transform.position = screenPos;
}```

[naive pawn]

well is the camera positioning also in OnLateUpdateView

[topaz mortar]

no, the camera follows my player object, which has no late update in quantum

it's cinemachine

[naive pawn]

imma be honest i'm not noticing weird positioning

[topaz mortar]

it jumps a little, as I press any direction, for example up, it shoots up a short distance, then goes back down a little
it's hard to notice but something is off

[queen adder]

I may be wrong, but it's probably better to loop through all the health bars and update their positions in a single update, instead of having each individual one update for itself, for performance reasons, but again I might be incorrect

[naive pawn]

wouldn't really matter, method overhead is tiny (and might mot even be a factor given the override thing)

[topaz mortar]

I don't know what that means 🤯

I think going with world space would prevent the zoom issue too, so might be better

[topaz mortar]

do you just mean I should do transform.LookAt(_camTransform.position - transform.position);

[naive pawn]

no you'd have to project the position onto the plane of the screen and then look at that

[naive pawn]

is the zoom issue that it stays consistent or that it doesn't?

[naive pawn]

you could use Vector3.ProjectOnPlane i think but i don't really know how to use that method

i guess the other thing would be WorldToScreenSpace then ScreenToWorldSpace lol

[cosmic charm]

is copying projects a good practice to learn how to make a video game?

[topaz mortar]

nope, it's terrible

well, depends on how you do it

[lilac kelp]

Yeah its a one of many way to learn the basic but you need to do a lot of those or make your own game and learn as you make the game that way you will learn fast also enjoying the journey

[topaz mortar]

I fed this line into chat gpt and it came up with this:

forward.y = 0;
forward.Normalize();
healthbarCanvas.transform.forward = forward;```
this almost works, except when you go above the unit, it becomes a line

and if I remoe the y freeze, it doesn't update position based on the camera anymore, it kinda just statically floats there not looking like it's above the unit

[sour fulcrum]

Copying by rewriting and setting up by hand could absolutely be useful for learning. Copy pasting entire chunks less so

[topaz mortar]

nah even rewriting isn't good

[sour fulcrum]

Tbh i’m not interested in hearing it from someone actively using chatgpt, respectfully

[topaz mortar]

the best way to learn programming is to watch a tutorial on a piece of code, close or hide the tutorial and try to write it by yourself, never just re-write code you can see, you will learn nothing

[cosmic charm]

It's way way harder for a beginner

like how would I know what draw gizoms is? or how would I know what object pooling is

[sour fulcrum]

Googling 😄

[topaz mortar]

because you just saw how to do it in the tutorial and are now doing it again by yourself
if you forget, re-watch the tutorial (or google), close the tutorial & google again and try to write it yourself

[sour fulcrum]

Though you don’t need object pooling when starting out

[topaz mortar]

I promise you your brain will remember nearly nothing after a few hours if you just re-write code (or worse copy/paste it) while looking at it

[cosmic charm]

He is saying that I should write the code myself and hide the code from the tutorial, how can I google something that I don't know anything about, you know?

[cosmic charm]

well for my first project I made a figthing game

and I needed that

[topaz mortar]

object pooling is an optimization, you never "need" it

[cosmic charm]

Oh I see now

If you mean it like that then yeah it's smart I guess

    void Update()
    {
        float horizontalInput = Input.GetAxis("Horizontal");
        float verticalInput = Input.GetAxis("Vertical");

        Vector2 movement = new Vector2(horizontalInput, verticalInput * Time.deltaTime);

        rb.linearVelocity = movement * speed;
    }
}``` ok now i can move left & right but still not up and down

yeah the verticalInput velocity isnt getting added

im printing it now

only horizontal is

[naive pawn]

why do you have Time.deltaTime there

[austere monolith]

so it doesnt matter your frame rate

[naive pawn]

it already didn't matter

linearVelocity is already unit/second

[austere monolith]

okie thanks it works now

[naive pawn]

Time.deltaTime is a conversion factor between "per second" and "per frame"

[austere monolith]

idk how i didnt know that but ok

thanks a lot man

ill rmbr next time...

[naive pawn]

your speed is units per second, so if you did the movement manually every frame, you'd need the deltaTime to convert that to units per frame
but velocity is also units per second, so you don't need the conversion in this case

[austere monolith]

i see

[past yarrow]

I just started Unity for today and for some reason the cam is so zoomed in while it wasn't yesterday and didn't touch anything since yesterday 🤔 How to solve that please ?

[grand snow]

change the ortho size on your main camera to not be soo small, also not a code question

[past yarrow]

ortho size ? You mean FOV ?

[grand snow]

ortho size if ortho, fov otherwise yes

I presumed 2d from how it looks + 2d light

If stuff that should draw is just not, your camera may be at Z 0 and your content may be there too. Can be solved by moving the camera back a tad on Z

[past yarrow]

Thanks 👍 Also my code doesn't work anymore for some reason 🤔 ☝️

[naive pawn]

elaborate on how it "doesn't work"

[naive pawn]

start with what boxfriend said

[prime mantle]

Done

Now what?

[naive pawn]

so what's the issue exactly?

what's not working as expected?

[prime mantle]

The joystick, I can't move it

If you see the video, you'll see that the move input variable in the input manager script isn't updating

That's the issue ig

[naive pawn]

oh it's probably not in the code then

(could confirm that by adding keyboard bindings and see if those work)

[prime mantle]

uhmmm it is in the code...

[naive pawn]

if those work fine, then either the joystick isn't hooked up properly, or it doesn't work in the editor for some reason

that would be an #🖱️┃input-system or #📱┃mobile question though

[naive pawn]

the issue is probably not in the code

[prime mantle]

i did ask in mobile, they sent me here

[naive pawn]

a code issue was a good guess, but it's apparently not the issue

[prime mantle]

i'll ask in input then

[naive pawn]

(make sure the virtual joystick is hooked up correctly)

[prime mantle]

uhhhh ig it is... wait i'm sending screenshots

[naive pawn]

(send it in #🖱️┃input-system)

[prime mantle]

okkk

[ivory bobcat]

Also, why do you have a null conditional operator on your rigidbody move position call? Last I recall, null conditional operators did not work with Unity Objects

[naive pawn]

they "work" but not as == null as one might expect

[ivory bobcat]

Right, they don't use the custom equality operator

[prime mantle]

so what should i change??

[naive pawn]

remove the ? (?. -> .) and just let it fail-fast if the component is missing

[ivory bobcat]

Remove the question mark from your rb?.Move...

If the member has a proper reference, you'll not get the Unity missing reference exception

[polar acorn]

Getting rid of errors is not getting rid of problems. If rb is null, it should throw an error. Null checking it gets rid of the error but just buries the problem that's still there

[prime mantle]

Still not working

[ivory bobcat]

Not working relative to...?

[prime mantle]

The joystick isn't working

[naive pawn]

it wasn't supposed to fix that

[prime mantle]

Ohhh

[naive pawn]

it was just a separate issue

[past yarrow]

like this ?

for (var x = -1; x < 1; x++) {
  for (var y = -1; y < 1; y++) {
    if (IsInGrid(tile.Coords.x + x, tile.Coords.y + y) && tiles[tile.Coords.x + x, tile.Coords.y + y].Value != 0) {
        neighbours.Add(tiles[tile.Coords.x + x, tile.Coords.y + y]);
    }
  }
}

[naive pawn]

gotta be <= 1

[past yarrow]

both for x and y ?

[naive pawn]

yeah

you want it to be -1, 0, 1

[past yarrow]

yes

[naive pawn]

if it was < 1 you'd just get -1, 0

[past yarrow]

makes sense

Doesn't work 😬

• Green : When I pressed that tile it only revealed that tile and not the adjacent "0"s
• Yellow : It revealed that tile + 3 in the red rectangle

I'm kinda confused on this behaviour 🤔

I think it's because of the != 0 part

yup 👍

[rocky canyon]

does -1 symbolize the bombs?

[past yarrow]

yes

[rocky canyon]

i may give it another shot as well. got ur "Easy" message.. ya i was overthinking the number thing

[past yarrow]

what do you mean ? 😄

[rocky canyon]

#💻┃code-beginner message

i was completely overthinking it

[past yarrow]

Oh 😄 Yeah try it 😄

[rocky canyon]

i was using the bombs to fill in the numbers..

i just need to use the squares to look for the bombs

[past yarrow]

huh ? How ?

[rocky canyon]

ya exactly

it didnt work that way 😅

[past yarrow]

I don't understand what you mean by that 😄

[rocky canyon]

instead of having each square count around itself for bombs..

i was using the bomb spaces to fill in the numbers around it

but then if i got to a second bomb in the vicinity of another bomb.. id have to re-do numbers that wer already done.

[naive pawn]

that wouldn't be an issue

[rocky canyon]

a 1 might become a 2.. and then it might even become a 3 later on on the next bomb.. sooo yea i was doing it bass-ackwards

[naive pawn]

it would actually be more performant

[rocky canyon]

ya, i probably could have finished it.. but i wrote it so bad that it became abig problem

[naive pawn]

well, if the amount of bombs is <= 50%

[rocky canyon]

i might do a side-by side now

just as a test

💪

[naive pawn]

for each tile:
  if tile is bomb:
    for each neighbor(tile)
      if neighbor is not bomb:
        neighbor.count++
```vs```py
for each tile:
  if tile is not bomb:
    for each neighbor(tile)
      if neighbor is bomb:
        tile.count++

[past yarrow]

I still don't understand it 😄 Do you mean like you generate the value of the grid from top left to bottom right and if your random generator generates a bomb for your current tile, you're kinda stuck for the previous tile that you already set a number for it and the next tiles would have the same issue later ?

[naive pawn]

this distinction is what spawn is talking about

[past yarrow]

oh it's from the perspective of the tile or the perspective of the neighbour, I see 👍

[rocky canyon]

ur using a space.. and then look around that space to find the amount of bombs to fill it in right?
i was doing..

ya ya.

i could have just skipped the bombs.. b/c they dont need a number

but i was filling in the spaces adjacent

yea

stupid lol

(atleast for my ass)... a nested loop is about all i can contend with

or to keep straight in my head.. grids are my kryptonite

[past yarrow]

• I Genereate all the bombs in grid first
• Get all the bombs tiles and fill the value of their neighbours
• All the other tiles don't need to be filled as their default value is 0

[rocky canyon]

let me see if i cant find my old code.. im sure it will give someone a laugh

[naive pawn]

i mean if you do it when you generate the bombs you don't need the n^2 step

[past yarrow]

not really a laugh but a way to learn 🙂

[rocky canyon]

oh no.. it was one of my first 2D projects.. its def laugh worthy..

it was a learning lesson back then

now its just disappointing lmao

[naive pawn]

hey i have minesweeper too lol

[past yarrow]

nice 😄

[naive pawn]

https://jsfiddle.net/That_Guy977/n5voxjf4/

[rocky canyon]

it was either that or "snake"

and snake seemed too ez

[naive pawn]

heh why not both (i did both)

[rocky canyon]

i could do snake real quick..

did u do urs the actual grid ways?

[naive pawn]

i mean tbf i kinda did them for fun, not with the intent of learning

[rocky canyon]

where u add a grid in front and remove a grid in back?

[naive pawn]

they're terrible and that's ok lol

[rocky canyon]

for movement

[naive pawn]

uhhhhh kinda?

[rocky canyon]

ya thats the way i wanted to do mine

and i kinda felt gate-kept

seems like something hard to do

snake movement

i mean.. tbh i feel i still made the right choice ^ i wouldnt know how to do this even today

since we're in beginner code anyone know the psuedo on how to do something like that ^
where the movement of the snake fills in the square ahead of it and removes the square at the end?

[naive pawn]

deque (via linkedlist in c# for example - or List but that doesn't scale well, in theoretical terms)

[naive pawn]

https://jsfiddle.net/That_Guy977/rq9uj4o5

[past yarrow]

does the snake have a V12 engine ? 🤣

[naive pawn]

actually i guess a queue would suffice, you don't need a deque

so you can just use the built-in Queue

[naive pawn]

yeah the scaling is definitely terrible lmao
that's what happens when you make something for fun tho lol

[naive pawn]

(btw @rocky canyon if you want to ask about stuff here feel free to open a thread and tag me. it's definitely not very good code lmao)

Then it seems you are not overlapping with anything on that layer. Does your overlap detect anything at all

[polar acorn]

https://dontasktoask.com/

[austere monolith]

oh shoot

[austere monolith]

the box has to have a box collider 2d....

[polar acorn]

Well it needs to have some sort of collider to be detected, yes

ohh i was making a mp game for mobile trying to dodge the mp coding things so i ended up somewhere with chatgpt"s script i spent one day figuring out this and wasted i cant just drop out from this project even tho its my second project if i give up i dont know ill lose motive or something

[austere monolith]

uh still doesnt work

[polar acorn]

So is your overlap detecting any objects at all? Does it detect anything on that layer? Try using logs

[austere monolith]

i recommend to get help not from chatgpt, only for minor things maybe. i find to learn better with help from real people

[austere monolith]

alright gimme few mins

[potent epoch]

where to get real people ? for free :)

ask you questions here lmao

[polar acorn]

This still isn't a question

[naive pawn]

that's.. not really something we can help with

no clue what the actual issue is

[polar acorn]

And people aren't going to commit to solving your problem in a DM when you won't even say what it is

[austere monolith]

seems like the only thing its detecting is the player

so its having some issue with the layer detecting

[austere monolith]

probably im doing something wrong with checking a layer.

although layer number 3 is Box

and the box object has the layer Box

so im not sure currently

ill re-check my scripts

[potent epoch]

Hey, I’m using Photon PUN 2 (free) for a mobile multiplayer game.

Each player prefab has a camera and a Canvas with joystick, sprint button, and stamina UI — all inside the prefab.

The player prefab is spawned using PhotonNetwork.Instantiate().

❌ Problem:
When Player 2 joins, Player 1 freezes — can’t move or look — and logs:

👻 Not my player, disabling input.

It looks like input scripts are disabling themselves due to this check:
if (!pv.IsMine) { ... }

Also: Players aren’t synced. Player 1 sees Player 2's head move, but the controls are hijacked.

✅ What I want:
Each player to have their own camera + UI + input working properly without affecting each other.

Any idea what might be wrong or how to structure this better? (this is not made from chat gpt)

[rich adder]

#archived-networking

[potent epoch]

U guys are killing me😂

[polar acorn]

Overlap only detects the closest thing. You should probably pass it a layer mask if you only want to detect one kind of thing

[austere monolith]

oh really now?

[polar acorn]

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCircle.html

[austere monolith]

yeah i looked at that but i didnt see the text i guess

[polar acorn]

There's an OverlapCircleAll that gets back an array of hits

You could do that and loop through them, but if you want to look for a specific layer anyway, you should just use a layer mask

[austere monolith]

right so it only detects one object; the closest one? ok, would CircleCast be any different?

[austere monolith]

yeah i will

[polar acorn]

Circle cast is basically firing a tennis ball in a specific direction. Overlap seems like what you want, you just want to set it up to only be looking for specific layers

[austere monolith]

alright ill try it out and see

        {
            if (((1 << hit.gameObject.layer) & interactLayer) != 0)
            {
                pickUpText.SetActive(true);
            }
            else
            {
                pickUpText.SetActive(false);
            }
        }
        else
        {
            pickUpText.SetActive(false);
        }``` seems to work

finallyyy, spent an hour on the if statement

[grand snow]

nice one, bitwise operations are a beginner thing

It could also be simplified to pickUpText.SetActive(hit != null && (1 << hit.gameObject.layer) & interactLayer) != 0;

(use the bool comparison result directly instead of using an if)

[pallid nymph]

(and if you don't want to be a barbarian you'd have 1 or 2 named bool variables to express what the condition means to check 😛 )

[grand snow]

yea its easier to debug if it goes into a bool and then is used. For simpler expressions its probably not needed if variables have good names

[muted sapphire]

Is there a good guide on how to implement dragging in Unity? I've just started trying to make an infinite runner type game but unfortunately, Unity is too complex to allow raw coding and too raw to simply bind an action to drag

as in

on a phone screen you drag right to move your character a lane right

unfortunately i dont know how to tell the scripts to utilize already given or existing variables

like touchscreen status

[eager elm]

save the mouse position when the button is pressed down. Once the player releases the mouse again calculate the direction from p1 to p2

[muted sapphire]

If it would be so nice, but I wish to actually have the game sitting on my phone

meaning i need direct touchscreen compatibility

[grand snow]

checking the last and current input pos gives you a "velocity" which can be used to detect a drag.

[muted sapphire]

its possible, i saw "touch" as an option, but i cant for the life of me figure out if it has "drag" as a preset or if i have to somehow read touch position in a script

[muted sapphire]

the big question is: how do i check input position?

im unfamiliar with unitys specific coding

i know c

[real grail]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Touch-position.html

[grand snow]

^ If you are using the NEW input system you can get mouse position as touch or mouse pos:
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/Touch.html

You can also enable Enhanced touch to get things that work like the old input system touch stuff (do not try first)

The new input system way would be to have mouse pos and touch pos go to a vec 2

[muted sapphire]

alright ill check it out

sorry if i sound stupid, i code a lot but ive never used unity or ue5 or anything of the sort

a little bit of guided godot but thats about it

i want to get into making games but unfortunately ue5 is even less beginner friendly so i ended here

[grand snow]

using the old input system you can grab Input.mousePosition each frame and get the difference (current - last):
https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Input-mousePosition.html

[wintry quarry]

If you're talking about a Subway surfers type game sounds like you are looking for "swipe" detection, not dragging?

Or possibly both

[muted sapphire]

is "dragging" object specific? or what sets it apart?

[grand snow]

It does imply you would move something

[muted sapphire]

ive been told to use the new input system and android exporting does not properly support using both systems, so says the popup at least

[grand snow]

Its telling you the option cannot be "Both" so you have to set it to "old" or "new" only.

[muted sapphire]

yeah thats what i did

but it means that if the new system is better, i unfortunately cant use the old system just for some singular items

has anyone just got a good GENERAL youtube guide series for unity? There's a lot going on that doesn't add up in my head

[grand snow]

There is plenty of content for unity online

[grand snow]

Check out the docs and quick start guide for input system: https://docs.unity3d.com/Packages/com.unity.inputsystem@1.14/manual/QuickStartGuide.html

I've done touch swipe detection before so I can give some pointers

[muted sapphire]

Just a quick question because this is gonna come up later: Is it possible to run scenes within scenes?

I'd use at least two scenes (Main Menu/Game), maybe more for different submodes within the run like flying or so, and it would require smooth transitioning with scenes

like showing a peek of the area within one tab of the main menu

[grand snow]

You can open multiple at once if you load others "additively"

[muted sapphire]

Let me rephrase it more clearly, that was very confusing, sorry

You know Subway surfers, yes?

The game has its tabs on the bottom and top, and then in the middle it has the animation of the guy spraying

then when you tap in the screen in that scene, it fluently goes into the run

That i need to do

Or rather, want

[grand snow]

I think that is not worth thinking about at this stage for you.
You need to tackle the basics of unity first

!learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[muted sapphire]

The thing is, I've learnt from much coding that usually, I need to think about this stuff first

Else I end with a mess thats, for example, all in one scene, and it's a hell to seperate it

[grand snow]

Well what you said is possible for sure but I think you should make sure you understand some more fundamental things with unity first

[muted sapphire]

But you are right, i should learn the basics first, i was just hoping that once i get some basics down, it would flow more easily

which it might

[naive pawn]

this would just be making the main menu not cover the entire screen in one tab and covering the screen in the others

[muted sapphire]

unless i misunderstand what scenes are used for id use a scene for the main menu

actually scenes in general are very confusing

[naive pawn]

scenes could be used for this

you don't have to

[muted sapphire]

do people just put the entire thing in one scene

[naive pawn]

again this is something that you can worry about later

[muted sapphire]

is that socially acceptable

[naive pawn]

there's many ways to do this, just keep that in the back of your mind when thinking about how it'll flow together

don't worry about the specifics just yet

get something working before you get something good

your first game won't be great, and that's ok - you get experience to make the next ones better

[muted sapphire]

that was why i was making an infinite runner

it can be expanded upon

and if something good actually comes of it theres plenty of directions one could be used

considering i have 0 actual models its just gonna be cube runner anyways

[naive pawn]

being an infinite runner doesn't really affect "it can be expanded upon"

anything can be expanded upon in terms of ideas if you're creative enough

[muted sapphire]

i rephrase: its easy to expand upon

and a generally really simple game principle

[naive pawn]

some things can be expanded upon in terms of implementing content depending on how you've designed the underlying systems

how the game plays doesn't really affect that

[muted sapphire]

...i really should just start by making a game that uses mouse and keyboard first shouldnt i

[wintry quarry]

You could make the runner game using just wasd controls for now

[naive pawn]

you could just reduce the scope of the project you have

[wintry quarry]

And add touch support later

[muted sapphire]

yeah that

[muted sapphire]

ill probably start over anyways

stuff always turns to a mess sooner or later

alright then lets start with the basics

So, now a basic question

how to i change the x position of a cube within a script

[naive pawn]

have you gone through like, unity essentials, junior programmer

[muted sapphire]

a link would be appreciated

although i might have it somewhere in my page salad

[naive pawn]

aight you should probably go through those !learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[muted sapphire]

unfortunately that link still doesnt work

[naive pawn]

(you can skip parts in unity essentials that you aren't using right now if you want)

[muted sapphire]

thank localization probably

[naive pawn]

wdym by doesn't work?

[muted sapphire]

by that i mean it redirects to a site saying "oops you broke the internet"

i assume this is because it autoredirects me to the de website which doesnt exist

ignore this

[naive pawn]

it's on de.unity.com or smth?

[muted sapphire]

its on https://learn.unity.com/de

[naive pawn]

funnily enough that page loads in english for me

[muted sapphire]

yeah i assumed as much

[naive pawn]

the "click here to go to livehelp" works for me, does that also redirect?

[muted sapphire]

yep

sends me to the same page

let me vpn and incognito

[naive pawn]

it seems that localization doesn't actually go through /de//ja/other slugs for me

perhaps you have a stale cache?

[muted sapphire]

full refresh doesnt help either

neither does vpning anywhere

so browser change it is

[naive pawn]

full refresh on learn.unity.com/de?

[muted sapphire]

yeah

or any other /xx links

[naive pawn]

you'd need a full refresh on learn.unity.com without the /de

[onyx geyser]

i took notes on all the basic things i needed to know, but now my next question is how would i know where they go in a script?

[muted sapphire]

can go to /en with the same result, even in german

[naive pawn]

yeah the localization doesn't actually go through those slugs

[muted sapphire]

i also went on incognito which i believe to have set to use an empty cache

[onyx geyser]

would anyone happen ti have a good tutorial that teaches you how to utilize the things you wrote and learn in what way to write them?

[muted sapphire]

browser change doesnt help either

[naive pawn]

this is something you have to practice, not something someone can teach you
make sure you understand all those, not just know them

break stuff down into smaller problems, etc

[muted sapphire]

im pretty sure this is just c# coding

you gotta familiarise yourself with the basics of that

or c

or c++

or really any other programming language

[onyx geyser]

well is there a good way to start at least? like how i would use transform and vector3 in the same statement (presuming i would use them in the same statement)

[naive pawn]

@muted sapphire what about like https://learn.unity.com/pathways

[muted sapphire]

theyre all just dialects to one another anyways when dealing with stuff like this

[muted sapphire]

works perfectly fine

[naive pawn]

that's a very ambiguous and unanswerable question

[muted sapphire]

depends on how you want to use them togehter

[naive pawn]

...damn, i didn't think it'd work

[muted sapphire]

what do you want to achieve

[muted sapphire]

im pretty sure the homepage is just broken on my end somehow

NO MATTER who needs homepages

[onyx geyser]

i know the terms, i just don't know HOW to write them in the script.

example, if i wanted to make pong, i have the tutorial but i have no clue how he knows how to place where things go.

[muted sapphire]

which is why its like i said

learn c#

or any coding language

its very simple

[naive pawn]

you don't know where stuff should go, this isn't like a jigsaw where everything has 1 specific place it goes
you design and decide where they should go

[onyx geyser]

so it's.. less like a puzzle and more like a lego?

[muted sapphire]

if we could fuse we might be the best coder

[naive pawn]

that's a very good analogy. i will be stealing that

[onyx geyser]

LOL

[onyx geyser]

what do you mean by that?

[muted sapphire]

You know the unity terms

[onyx geyser]

oh you mean how i know the terms

[muted sapphire]

I know how to code

but i havent a damn clue how to make my code tell Unity to do something

[onyx geyser]

yeah, i know a good portion of them and their uses now, i have a bunch of notes on the ones i know at least

i sent them to one person, he said they were good, few chop ups here and there

[naive pawn]

great time to pull this out it seems

[muted sapphire]

Language you can learn from youtube to the respective language

Logic comes naturally when you begin to understand the syntax and what you actually do

Library is what I'm missing in this case, because I can't tell my code to, for example, move a player, but i can perfectly calculate where it's supposed to be

[onyx geyser]

so you have the wood and hammer, you have the blueprint, but you don't have the screws?

[muted sapphire]

I'm missing the specific screws that would put what I've made to the rest of the machination

[onyx geyser]

that makes sense

i think i'm gettin an idea

[naive pawn]

you're missing the proprietary screwdriver lol

[muted sapphire]

And I still forget the DAMN SEMICOLONS

EVERY SINGLE DAMN TIME

[onyx geyser]

even knowing the terms you still have to functionally put them together

[naive pawn]

yeah that sounds about right for coding

[onyx geyser]

i've begun correcting myself on semicolons, capitalization, and spelling, those seem important

[muted sapphire]

yep those are the worst mistakes

[onyx geyser]

i kept making them when i made that flappy bird tutorial

[muted sapphire]

together with plus and minus errors

[naive pawn]

hm you didn't have autocomplete?

[onyx geyser]

suppose i can see if i can't make pong on my own today rather than follow a tutorial

[onyx geyser]

i had autocomplete, i still messed up a lot

[muted sapphire]

but that usually only happens when you do a programmer and just scatter random - signs around your code when stuff doesnt work

[naive pawn]

real

i was writing kinematic stuff a few days ago and i just could not get it to work and i checked my math so many times

i had forgotten Time.deltaTime in applying acceleration lmao

[onyx geyser]

can i get my notes judged?

i would like my notes judged

[naive pawn]

idk about judging, proofreading maybe

[onyx geyser]

that works

just need someone with more experience to look at them and see how well i might've done

ofcourse i wrote them IN cs.

[naive pawn]

you probably don't need that Unity.VisualScripting

[onyx geyser]

eh, it came with the thing

i never bothered to change it

[naive pawn]

i feel like that'll confuse your future self

[muted sapphire]

In school we're doing Coach7 (no idea if that software is common) but thats basically all about that math and it usually ends up looking like a bomb defusal too

[naive pawn]

if you're writing in c#, you'll generally never touch VisualScripting

[muted sapphire]

VisualScripting is somehow harder than normal scripting

[onyx geyser]

well i have little idea what it is, i just grabbed it from a scipt file in unity and started writing notes

[naive pawn]

visualscripting is unity's block code thing

[onyx geyser]

lets not worry about that top part, it's the notes i wanted proofread, as a beginner with no experinces

[eternal needle]

your IDE might've added it if you tried to use something from the visual scripting namespace, like a class. this happens often

your IDE also might have a code cleanup function to remove unused using statements

[onyx geyser]

i think it might be that, i remember having to update my IDE manually and i think i left something unclicked

[naive pawn]

RigidBody2D //a physics body
Transform // the position of the edited object
gameobject //a type that can appear in the inspector?
quaternion.identity //no rotation
vector2-3

you're mixing types and values here - capitalization is important, Transform refers to the class, transform refers to the instance of Transform on the current gameObject

[onyx geyser]

[naive pawn]

honestly i'd recommend not having this in a .cs file, that way you have more freedom in how you structure your notes
you have if..else, a very fundamental concept, quite far down, separated from for which is in the same category of control flow

[onyx geyser]

i'll only defend myself by saying this is my current understanding of how the terms work

otherwise this is pretty sweet

[muted sapphire]

markdown files ftw

[muted sapphire]

if it works on your end

alright i checked out the new input system

but it seems oddly complicated

[naive pawn]

also this doesn't work

GetComponent(doorlocked = false);

[muted sapphire]

what happens to "getKeyDown" but no we do "horizontalAxis"

[onyx geyser]

yeah i know, thought i put a note saying that it wouldn't work

i was just using it as a "this how it would look theorhetically, because i don't know how it actually looks"

[muted sapphire]

That's not even the new input manager

What kind of sorcery is that

[onyx geyser]

i intend to come back to this file when i learn more so this is helpful

[naive pawn]

there's one at the bottom for a separate line of code?

just not for this one

[onyx geyser]

oh, oh yeah wait you're rightr

maybe a fore warning at the top would be better

[onyx geyser]

so would you be able to explain this with an example at all?

[naive pawn]

and yeah, definitely this - would help in structuring your notes a lot
could have separate sections, inline code/codeblocks, lists, checklists

i wouldn't use an example for those

[onyx geyser]

also intended to get to that when i knew more about what i was doing

[muted sapphire]

stupid idea

but just try coding a calculator in C#

[onyx geyser]

:((

[muted sapphire]

or something

[onyx geyser]

oh

LOL

[muted sapphire]

NONONOTHATWASNTWHATIMEANT

MYIDEAWASSTUPID

[naive pawn]

(do you actually have a question? i can't tell lol)

[muted sapphire]

I was trying to ask whether i had to use the fancy input system package and all the settings that come with it

[naive pawn]

well, if you want to use the new input system, yeah?

[muted sapphire]

or whether i could just make my code check if a key is pressed using it

[naive pawn]

you can do that with either system

[muted sapphire]

the old input manager is almost as complicated

[naive pawn]

it's input

that's how it is

[onyx geyser]

welp, time to remake the entirety of the ps2 game 'shadow of the colossus' with my current knowledge.

[naive pawn]

the real world is messy 😭

[muted sapphire]

you won't believe how well my code will fit in

[naive pawn]

it won't, they're different kinds of messy

orzo and spaghetti don't look that cohesive.. i don't think

[eternal needle]

not really, there isnt much to the old input system. the new input system definitely has a steeper learning curve because it comes with way more features and can be customized quite nicely

[muted sapphire]

alright now, how would i get if "up" is the current state

the tutorials are for the old input manager

[eternal needle]

there are tutorials for the new one as well. "new" being a couple years old already

#🖱️┃input-system has pins with resources

[muted sapphire]

oh yeah i use unity6 btw

[naive pawn]

it doesn't have a state, it just has a value for the Move action

up just means y will be positive when the binding is triggered

[muted sapphire]

okay, but how do i get that in code

[naive pawn]

(that kind of question would be more suited for #🖱️┃input-system fyi)

[muted sapphire]

input.Move.y seems a bit excessive

and it wont work i can tell you that much

[naive pawn]

there's like, 6 separate ways to do so

new input system is really flexible, hence the "steep learning curve" comment

[muted sapphire]

for now, i just wanna make a cube move whereever i tell it to with my wasd

[naive pawn]

i mean, if it's in a composite like that then you'd want to use the entire Vector2, no?

[muted sapphire]

you speak in riddles

maybe im too used to manual this

[past yarrow]

Guys why does it complain when I subscribe to my event and the method is a Coroutine please ? I think I'm missing a StartCoroutine() somewhere but I'm not sure where (it says : Expected a method with 'void OnGameOver()' signature)

[naive pawn]

did i use a word there that's unfamiliar

[muted sapphire]

Vector2

i know what a vector is

[naive pawn]

yeah invoking the event would just call the method instead of passing the enumerator to StartCoroutine
you'll need an intermediate method to handle the unsubscribing

[muted sapphire]

but Vector2 specifically

[naive pawn]

a Vector2 is a vector with 2 dimensions, x and y
https://docs.unity3d.com/ScriptReference/Vector2.html

same thing for Vector3 but with z added

that's as far as unity goes in the core lib

[muted sapphire]

And how would I get the entire "Move" Vector3 (or two, if that is that) from the Input system?

[naive pawn]

it would be the theoretical input.Move from before (it'd just be a Vector2 here, only 2 dims)

i'm typing it out give me a sec lol

[muted sapphire]

so "input.Move" describes a 2 dimensional array

or returns it

makes no real difference but it would force me to use ()

well shoot me i dont even have the input system imported

[past yarrow]

And what should I return at the end ? Here I'm returning null but it's more like as default choice.
Also do I have to save the coroutine in a variable to clear it later or as I'm reloading the scene, it will handle the clearing for me ?

[naive pawn]

options, in no particular order (because i don't have the brainpower to sort them right now)

• InputActionReference as a serialized field, poll that
• InputActionReference as a serialized field, subscribe to that
• PlayerInput component with messages
• PlayerInput component with UnityEvents
• PlayerInput component with C# Events (not sure what that entails)
• Generated class, poll that
• Generated class, subscribe to that

you should probably find a tutorial and then just go with whatever that tutorial uses

[muted sapphire]

unfortunately the coding beginner guide on the main page uses input manager

how do i import it in the first place?

[naive pawn]

it's not a 2 dimensional array, rather it's a 2 dimensional quantity (you could view it as a 2 element array but it's technically a struct)

[muted sapphire]

one dimensional, two element array, im tired sorry

[naive pawn]

there are separate inputsystem tutorials, but if you're not very familiar with gestures vaguely at everything you might want to just stick to the tutorial for now

[muted sapphire]

the tutorial is unfortunately being very weird around this corner

[naive pawn]

anyways more realistically input.Move would be an "input action" that you can get stuff from, like GetValue<Vector2>()

[muted sapphire]

ah there, i found some semi decent guide on input system

let me copy paste half the code segment and then figure out what it does

[naive pawn]

1. you don't need to return anything at the end. it'll exit automatically when it reaches the end of the method (since it's an enumerator, you can't actually return;, you yield break; to stop the enumerator. yield return null; gives a value, which amounts to waiting a frame for a coroutine.)
2. coroutines exit and handle themselves

[past yarrow]

yield break, my IDE says Redundant control flow jump statement

[naive pawn]

yes because it's at the end. it'll exit itself

you know how you don't need to return void methods?

[muted sapphire]

IT MOVES

[past yarrow]

yeah

[naive pawn]

yeah there's an implicit (aka automatic) return at the end

[past yarrow]

oh ok, thanks 👍

[naive pawn]

same thing here except with yield break

an enumerator is something that gives a sequence of values
when you write a coroutine, you're building that enumerator by specifying the sequence of values
yield adds a step to the sequence
yield return x; adds the value x to the sequence
yield break; specifies the end of the sequence

[whole flare]

Hey everyone!

Is there any possible way to add unity messages(info on Unitys Methods) on Visual Studio Code?

[past yarrow]

That looks advanced 😛 I use it right now only for coroutine to wait some amount of time before doing something else 😄

[whole flare]

Like in viusal studio

[past yarrow]

Yes : https://learn.microsoft.com/en-us/visualstudio/ide/reference/generate-xml-documentation-comments?view=vs-2022

[naive pawn]

think of the coroutine yield returns as yielding delays

[naive pawn]

not what they're referring to

[past yarrow]

are you sure ? 🤔

[whole flare]

I mean just to hover on the methods and see documentation

[past yarrow]

Yeah I think that's what I sent above 🤔

[naive pawn]

real quick - is it specifically unity messages, or just stuff in general?
i don't get documentation boxes on hover, only when writing methods

[naive pawn]

yes, they aren't asking about writing docs, they're asking about seeing them

[past yarrow]

Oh ok, my bad 😄

I would suggest to switch to Rider, it was the best decision I made 😄

[whole flare]

Yeah that works beacuse of the comments /summary, I want just when i hover on to see them like in vs code

[whole flare]

no just unity mesagess

[naive pawn]

that's intellisense, not docs

[whole flare]

yeah and in visual studio u get this

[past yarrow]

This is how it looks like in Rider fyi 🙂

[naive pawn]

yeah but you don't get any in vscode, right? not just unity messages

vscode seems to have these kinds of settings, but there's nothing for c#, so i don't think this is something you can get with the microsoft extensions. maybe there's a thirdparty extension to do that

[whole flare]

any what sorry i dont get u

u mean dis?

[whole flare]

Why the message is different from Visual studio? I just want the excact same messaes that are shown in visual studio in visual studio code

[past yarrow]

I have this issue and don't understand how to solve it as the scene is already in the build profile 🤔

[naive pawn]

you're trying to load the scene from itself, or...?

gotta give some more context here

[past yarrow]

I'm trying to reload the same scene I'm in

[naive pawn]

ah, ok, so they are supported
vscode's, uh, decompilation? just doesn't have very many comments
and messages probably just aren't documented

[polar acorn]

Try logging the scene name before you load it

See what it prints right before the error

[naive pawn]

have you tried debugging the thing you're trying to load? i can guarantee it's not what you want lol

[past yarrow]

@naive pawn solved, thanks 👍

I thought GetActiveScene() returned the name but I had to use name property

static variables aren't reset when loading a scene again ?

[naive pawn]

it returns a Scene

[muted sapphire]

alright im calling it a day for today, the input system is getting to my head

they really arent letting me just get what keys are currently being pressed are they

I'd gladly manual the entire movement thing but I can't get it to just give a boolean true for as long as a key is pressed

[naive pawn]

you wouldn't use a bool though, regardless of movement system

you'd just make a vector out of the 2 axes (for the old one) or take the vector that's the same thing but done for you (for the new one)

[past yarrow]

What about this please ? ☝️
And also do events get properly cleared when loading the same scene like I do right now ?

[wintry quarry]

When you unload a scene all the objects in that scene get destroyed.

When you load a scene non-additively, all other scenes get unloaded

Static variables have nothing to do with scenes at all

so they're completely unrelated

[past yarrow]

then why my variable gameOver doesn't come back to its default value (false) when reloading my scene ? 🤔

[wintry quarry]

Why would it?

Didn't you just say it was a static variable?

[past yarrow]

yes it is, that's why I asked the question because I don't know the behviour of static variables 😄

[wintry quarry]

I'll point back here

It's a bit like asking "How come the hat on my head didn't change when I got in a new car?"

[past yarrow]

Oh Ok I understood now

[mossy jasper]

ik its not code related but i cant find the player input script and im on unity 6, i need some help

[past yarrow]

Where is your "Player Input" script ? Because your C# folder looks empty

[mossy jasper]

i added that for later, but there should be a script component called "Player Input"

[past yarrow]

why "should" ? If you didn't create it it won't be there. Are you following a tutorial ?

[mossy jasper]

Yes im following a tut

[past yarrow]

Are you referring to this ?

[mossy jasper]

YES THATS IT!

[past yarrow]

Did you install the "Input System" package ?

Go in the top menu > Window > Package Manager > Search for "Input System" > Install it > try to find the script again

[mossy jasper]

ok

how do i download it?

[past yarrow]

click on the little icon for "Unity Registry"

and search it there

[mossy jasper]

got it, but do i say yes?

[past yarrow]

Yes

[mossy jasper]

ok

[mossy jasper]

thanks for the help

It looks like your Game manager is a singleton but isn't a DDOL, so when you reload the scene it destroys itself

[covert obsidian]

i wanna update a text based on a variable. is the easiest way to do it in the "update" place in the script? i wouldn't think it's good to call it every single frame since the variable isn't gonna change every single frame

[slender nymph]

invoke an event where you set the variable and change the text object only when that event is invoked

[covert obsidian]

that would require sending that event every time the variable is changed, correct?

[slender nymph]

yes

[covert obsidian]

ok, thanks 👍

[slender nymph]

this is easiest done by using a property and changing the variable's value and invoking the event inside the property's setter then just assign to the property everywhere else you are changing the variable instead of assigning to the variable directly

[nimble apex]

can you register async Task into button event?

theres a function that must be async Task

in login manager

    public async Task GoogleLogin()
    {
        Debug.Log("Google");
    }```
in another UI
```cs
    private void Awake()
    {   GoogleLogin.onClick.AddListener(LoginManager.Instance.GoogleLogin);
    }```

i guess i just turn it into void then

[muted sapphire]

No, like, literally a boolean "isPressed"

If I could just get an output telling me if a key is pressed or not my life would be much easier

[burnt vapor]

Haven't read the convo but I assume you have learnt of the two input systems available?

[onyx geyser]

would there be any particular reason that, when a bounce physics matieral is applied to a rigidbody2D and box collider, upon making contact with a wall, it's speed seems to multiply excessively?

[burnt vapor]

If so, it's a matter of picking which one to use and then using it. Not much else to it

Preferably the new system

[onyx geyser]

to the point that it actually breaks out of the walls i've trapped it in

[muted sapphire]

I have, but was told the new one is better

[burnt vapor]

It is

I mean, in comparison the new one is set up much better and allows for cross input much better

[muted sapphire]

But I'm currently at a point where I'd rather manual the motion outputs in my code than actually fight with the motion system

[burnt vapor]

You can use the old one, especially if you purely use just a keyboard

[muted sapphire]

ironically, I want to eventually switch to touchscreen

[burnt vapor]

Then I'd do it correctly and use the new one from the very start

TBH even if you dont need cross input the new system is better

Just shoots yourself in the foot once you do need it somewhere

[muted sapphire]

depressing, the new one is kinda weird when using simple movement

its an infinite runner, its literally got three possible states plus height

[burnt vapor]

The idea is the same, I don't see how simple movement makes a difference

But maybe you can share your code and it can be reviewed

[muted sapphire]

Because it feels overly complicated

No like I have no idea what I'm doing with the new movement system

But so far I've gotten Vector2s out of jt

[onyx geyser]

isn't it literally a getkey(KeyCode.W)

[muted sapphire]

Which is way unnecessary for a movement system with three states plus height

[muted sapphire]

Didn't work for me but I'll try again

[onyx geyser]

then multiplying the movement by whatever public int/float you use

then multiplying by Deltatime so it doesn't turn into fallout 76

(context, in fallout 76, movement was directly tied to framerate, which meant if you looked down on at the floor to unload everything, you moved faster.)

[muted sapphire]

yeah unfortunately some games do that (looking at you risk of rain 2 update)

[onyx geyser]

it could also be that the movement script isn't connected to your Rigidbody or whatever you decide to use

[burnt vapor]

Yes, but this is the old system

This won't work for touch screen

[onyx geyser]

the way i'm using it?

ohhh

ok

[muted sapphire]

It just seems overly complicated to run a whole input system for something that can be "0, 1 and -1"

[burnt vapor]

I'd dive in and learn the new input system considering it's good knowledge and you will always use it in your games. Even if it gets a bit more complicated

[onyx geyser]

well, as far as i know, it's more complex to make actually running it easier, say if you wanted to use a controller or something like that you could easier attune it, right?

[muted sapphire]

So is there a proper handbook to it?

the new movement system i mean

[onyx geyser]

unless i'm big stupid, that's just the idea i got from others who were talking about it

[muted sapphire]

that and to simplify complex interactions with the code

[onyx geyser]

i'm still trying to figure out why my ball is increasing in speed, or if there is a way to put a cap on it

[muted sapphire]

Oh i might be able to help with that, that seems like a coding issue

What exactly is the problem?

[onyx geyser]

it hits a wall, and it's speed seems to double

just, y'know, nyoom

[muted sapphire]

you willing to send the code?

[onyx geyser]

{
bool isRight = UnityEngine.Random.value >= 0.5;

float xVelocity = -1f;

if (isRight == true)
{
    xVelocity = 1f;
}

float yVelocity = UnityEngine.Random.Range(-1, 1);


rb.velocity = new Vector2(xVelocity = Flyspeed, yVelocity = Flyspeed);

}

just something i followed from a small tutorial

kind of using it as a test to see how much i actually understand

doesn't seem to fly in any random direction either, which sucks, but that's less important

[muted sapphire]

okay so let me go through this snippet

first you randomize if it goes left or right

or how far it goes right

[burnt vapor]

Randomized left or right

[onyx geyser]

randomize left or right?

[burnt vapor]

I won't comment on the quality of this code

[muted sapphire]

yeah thats unitys own feature cant really work on that

[onyx geyser]

LOL, guess the tutorial i followed wasn't very good (go figure)

[muted sapphire]

wait what the hell

why is a >= chained with a = in a single statement

and why does it work

[burnt vapor]

These are basic comparisons

>= means "larger or equal to"

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/comparison-operators

[onyx geyser]

which is probably the area that it can travel to

[muted sapphire]

ohhh its implied

[onyx geyser]

right?

[muted sapphire]

Sorry, I'm not used to C#, I was expecting a () around the comparison to recieve a boolean

[onyx geyser]

with isRight being a general direction it can travel in? i assume?

[muted sapphire]

at least that's what I would'vs done

[onyx geyser]

i wish some of these tutorials described what they were doing

[muted sapphire]

I should read a short booklet on C# someday so I know its exclusive terminology

like -1f and 1f (which i assume is just to make it be a float value)

[onyx geyser]

actually, do i even need isRight?

since it's all seemingly handled by rb.velocity

unless that's me being dumb again

[muted sapphire]

you do

it's used in the calculation of xvelocity

which is used in the calculation of rb.velocity

[onyx geyser]

doesn't seem to be very random

as it swings straight out or slightly down (which i assume is the .5 at work)

[muted sapphire]

actually hold on

[burnt vapor]

Sounds like you are used to if-statements, these always have them

[muted sapphire]

you set it to "Flyspeed"

[onyx geyser]

so change the speed in which it flys-

oh

well hang on

[muted sapphire]

you arent using your values at all

you're just using Flyspeed

[onyx geyser]

yeah i see that

i wonder why that was the way it was in the tutorial

[muted sapphire]

you might wanna xVelocity*=Flyspeed

or if that isn't a thing in C# xVelocity=xVelocity*Flyspeed

[onyx geyser]

heheh

the first one didn't do anything

what would xVelocity=xVelocity do?

[muted sapphire]

well what is Flyspeed

what value

[onyx geyser]

it's the speed at which the ping pong ball flys

flies

set to.. currently 3

but i have a range on it that lets me change it

unless it is that range that is causing it go faster

[muted sapphire]

okay hold on that entire code is a bit wonky

I need a second to work with that

[muted sapphire]

the line i sent sets xVelocity to itself times Flyspeed

which i think should be correct

I love how the x value is randomized by this unnecessarily complicated snippet but then y value just gets a one liner

[onyx geyser]

other way around?

but yeah i thought that was weird

also it's still increasing in speed

wish there was a way to lock the speed at which it's velocity increases

because it's going absolutely nuts

[sour fulcrum]

think about what locking the speed entails

logically

[onyx geyser]

probably keeping at a singular consistent number right?

[sour fulcrum]

do you want to lock the velocity, or how much it increases by

[onyx geyser]

well, that's the problem i ended up with when trying to find it, by locking it, it'll never increase to it's maximum

so i guess i want to limit, not lock

[muted sapphire]

in order to help with that I'd need to know how you handle walls

[onyx geyser]

it's a simple invisible box collider

that's all

[muted sapphire]

and there we leave my expertise again

[onyx geyser]

pfff

[onyx geyser]

suppose the answer would be i want to stop it from increasing past my flyspeed slider

thinking about it, i can probably do a reverse flyspeed if/else, just need to figure out how to write it, but it may be easier to find a set of words to actually lock at a certain speed.

[lusty star]

so i have this problem where when i auto complete code it doesnt add the right amount of space

[muted sapphire]

what do you mean? looks good to me

I'm like 90% sure C# doesnt watch syntax
