Is that possible to make UI in unity 2d by html / css?

[teal viper]

Not exactly html and css, but ui toolkit/builder uses a similar language.

[warped vale]

what im i supposed to do in this situation

[obtuse axle]

Hello, I have a question about character jumping and movement, when i jump while running, it doesn't jump as high as when im not running or moving. Is this a frequent mistake in the code?

[wintry quarry]

yes it's a mistake in your code

[wintry quarry]

provide keystores or passwords in the publishing section of the project settings for your target platform

[warped vale]

oh ok thanks

[obtuse axle]

Then how can i keep the same jump height in my code?

Is there something to add or to remove?

[eternal needle]

You shouldnt be using 2 moves per frame with the cc, try to combine it to one. Also you really shouldnt move the position directly

Jump height could be a side effect of the 2 moves

[lusty flax]

I parented my character to a kinematic rigidbody moving platform in order for it to move with it. However, it is not moving with it normally. I change the rigidbody's position by setting its velocity. Does that cause a problem?

[obtuse axle]

Uh the 2 moves?

[eternal needle]

Parenting isnt good for rigidbodies, because a child object will just be updated via its position. It has no respect to physics

[eternal needle]

The character controller .move

[obtuse axle]

Oh i see

[lusty flax]

okay... then how do i make the character stick to the platform?

[eternal needle]

Doing it with rb is kinda tedious. You can try to apply the same velocity (from the platform) to the player but it might not work if the platform moves with rotation

If it's simple movement it should work fine

[lusty flax]

it doesn't move with rotation

[young lava]

If I have a nested Enum called ActionType in my PlayerController class, and I set the variable ActionType actionType using a method called SetActionType. If I wanted to call SetActionType in another script, would I use the line:

playerController.SetActionType(PlayerController.ActionType.Attack);

[pallid nymph]

Yes

[cosmic dagger]

The best way to find out is to test it . . .

[warped vale]

can u show me where that is

[wintry quarry]

no because I don't have enough information. I don't even know which platform you're trying to publish for

[foggy lion]

I'm having a issue with prefabs, I'm not sure how to describe my issue so I attached a video (With text) below. Please help me if you can.

[ivory bobcat]

What component does the manager have?

[ivory bobcat]

If it doesn't have the block instantiator component, you'll not be able to drag it in

Also prefabs know nothing of the scene so they cannot reference scene objects

[foggy lion]

Oh

Hmmm, that may be the issue?

Is there anyway to fill those slots in my code, instead of having to drag the Block Instantiator into them?

[ivory bobcat]

Likely so. Any scene can be active at any given time. The prefab is always available though so having it reference a scene object makes little sense.

After you instantiate it during runtime, provide the appropriate references.

var instance = Instantiate(...);
instance.instantiator = this;//or whatever applicable```

[foggy lion]

What if I used GetComponent on Awake?

[small mantle]

Why is this sometimes jumping three times the height? ```cs
if (jumpInputLetGo && isGrounded) {
rb.velocity = new Vector2(rb.velocity.x, instantJumpSpeed * multiplier * Time.deltaTime);

    }```

It is sometimes a regular low jump (As I Want), but then sometimes it will jump three times that height. For context jumpInputLetGo is GetButtonUp for SpaceBar

[feral oar]

my first guess is that multiplier might be getting altered somewhere

hard to say without the full context, though. you should do a copy paste in one of those "blocks of code" websites so we can see the whole script

[small mantle]

multiplier is a const

[ivory bobcat]

Delta time can vary. Consider providing a fixed constant value if you aren't having to process something over time.

[ivory bobcat]

Should be fine as a means of acquiring a reference to itself (a component on it).

[small mantle]

What do you mean by provide a fixed constant?

[ivory bobcat]

Remove Time.deltaTime

[foggy lion]

I just keep getting "An object reference is required for the non-static field, method, or property 'BlockInstantiator.SpawnRandomObject()'CS0120"

But I do seem to be referencing an object, the prefabs I think

[ivory bobcat]

Maybe show the code.

[foggy lion]

Yeah

One sec

[wintry quarry]

On that line you're trying to use the class name instead of the reference to access your method

[ivory bobcat]

I'm assuming you've got a static member trying to access a non static member.

Can you show an image of the error - complete stacktrace

[ivory bobcat]

The stacktrace would be the details pane when selected

[wintry quarry]

this is a different error

[raw sun]

https://gdl.space/udobapicaj.cs
Like this?

[wintry quarry]

this is saying BI is null at runtime when you try to access it

the other error you showed was a compile error

[foggy lion]

Oh

Huh wait

One second

I think

Ugggh I think I showed the wrong error right before I changed something

Sorry

[foggy lion]

Also I'm not really sure where to find the details panel you are talking about

[ivory bobcat]

Destroy(col.gameObject);```

[foggy lion]

Is it a setting I may not have enabled?

[summer stump]

No

When you click the error in the console window, it will show more information right there, also in the console window

[foggy lion]

Oh oh

This thing?

[summer stump]

Yep

[foggy lion]

Note to self, the strange box on the bottom of the errors console is called the stacktrace!

[summer stump]

Interesting that it doesn't show more though

[wintry quarry]

well it's actually just an expanded view of the full message, whatever that may be. In the case of an exception, that would show the full stack trace

[ivory bobcat]

Also, you're probably not wanting to destroy the player when it's velocity is greater than -100 but instead if it's velocity is less than -100. @raw sun

[raw sun]

Alright.

Uh when I fix it. It got error like this.

[summer stump]

What is line 70

[raw sun]

Destroy(col.GameObject);

[summer stump]

gameObject not GameObject

[raw sun]

Ah ok

Thank you.

[foggy lion]

So @ivory bobcat, do you think you know what my issue is

Its saying that line 39 is referencing an object without saying what object its trying to reference.

Which doesn't make much sense to me, because I tested the code that actually spawns the prefabs, and it works.

[wintry quarry]

This is line 39

[foggy lion]

So its having some issues referencing the function or the script I guess.

[wintry quarry]

BI.SpawnRandomObject();

[foggy lion]

Yeah

[wintry quarry]

Thje problem is that BI is null

that's the only possiblity

[foggy lion]

But is BI not set to BlockInstantiator?

[wintry quarry]

BI is a reference variable. and it's not pointing at anything

[foggy lion]

at like 13

[wintry quarry]

BlockInstantiatior is a class

that's just the type of the reference

[foggy lion]

Right...

[wintry quarry]

Do you know what a reference is?

[foggy lion]

I think so

[wintry quarry]

A reference is like a piece of paper with an address on it

[summer stump]

That is a declaration, not an assignment
Declared but annasigned means null

Ah, miscounted. That's why posting longer code should be in links

[wintry quarry]

if the reference is null, it means the paper is blank

when it's assigned properly, it has the address of an actual house

You are trying to assign it here: BI = GetComponent<BlockInstantiator>();

but GetComponent will return null if such a component doesn't exist on the object you're trying to get it from

which in this case is the same object this script is attached to

[foggy lion]

Ooooooh

I think I get it

[wintry quarry]

Is there a BlockInstantiator on the same object as this script?

[foggy lion]

No, because its attached to a empty game object which is meant to act as a manager of sorts

[wintry quarry]

if not, you aren't assigning your reference properly

[foggy lion]

My issue is that I need to reference that manager game object

and I know how to do that

But it won't let me do that on prefabs

[wintry quarry]

assign the reference after you spawn the thing

Is this the prefab that the block instantiator is spawning?>

[foggy lion]

Yeah

Its a mess of code tbh

[wintry quarry]

you're making your life harder with the GmaeObject reference tbh

[foggy lion]

Yeah

Im trying to do it in code

And thats where we are now, me not understanding how to do that.

[summer stump]

Usually always better to instantiate from a component than a gameobject

[wintry quarry]

But you can do this:

GameObject myObj = Instantiate(myObjects[whichItem]);
if (myObj.TryGetComponent(out FallingBlocksScript fallingBlock)) {
  fallingBlock.BI = this;
}```

(after making BI public)

[foggy lion]

AAAAHHHH

THAT DID IT

THANK YOU SO MUCH DUDE

Uh oh

Wait

Well it did work for a bit

Then all of the sudden it spawned in like a thousand prefabs lmao

[wintry quarry]

sounds like an unrelated bug

[foggy lion]

Probably

[wintry quarry]

maybe one of your prefabs has a block spawner on it

[foggy lion]

Indeed it does

Im tired lol

Well actually

None of them have the Block Insantiator script

This block spawning has plagued me for days

[ivory bobcat]

Is the block falling script on the object instantiated?

[foggy lion]

I don't think its that

It looks like an issue with one of my coroutines

[ivory bobcat]

BI is null because the component doesn't exist on this object

GetComponent returned null

[hot wave]

is getcomponent bad? and should i start changing it as early as possible, or ok for starting?

[foggy lion]

I think I see the error

[ivory bobcat]

If this object is the instantiated object and the manager has the necessary component, after instantiating it with the manager set the public field to the manager in the manager script

[foggy lion]

And its really dumb (I think)

[hot wave]

If It is null, i put !null in if statement I think, but not sure if ok here

[foggy lion]

    {
        fallingCoroutine = StartCoroutine(FallRoutine()); //Here

    }

    void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Ground"))
        {
            CanMove = false;
            Debug.Log("BlockTouchingGround");
            StopCoroutine(fallingCoroutine);  //Here
            TouchedGround = true;
        }
    }```

Idk why I did this, but I believe I fixed it (changed StopCoroutine(fallingCoroutine); to StopCoroutine(FallRoutine());

[ivory bobcat]

It often leads to issues of NRE due to implicit requirements of needing the necessary components on the object to not be null. Other than that, there are some minor overhead.

[foggy lion]

Ahh, unfortunately that was not it...

Well actually it partially was

Im no longer getting errors

Its just spawning thousands of prefabs now

So much better...

As soon as one block collides with another, it all goes haywire, but when they just touch the ground, its all fine...

Uh oh

It won't let me back into my Unity window

I hope I didn't lose a lot of progress

I think i know what to do to stop a million blocks from spawning

[cobalt creek]

for(int x = 0; x < size; x++)
        {
            for(int y = 0; y < size; y++)
            {
                GameObject gu = GameObject.Instantiate(
                    gridUnit
                    ,new Vector3(x/1.5f, y/1.5f, 0)
                    ,Quaternion.identity
                    ,GameObject.Find("Lobby").transform);
            }
        }

so this script i create quickly for testing and the result is in attachment. Basically it create a grid of squares in x and y and I want to make the 100x100 squares contact perfectly without overlap

but when i dont divide by 1.5, I get the spacing in the grid. Why is that?

[acoustic sun]

I am getting an error saying: The variable audioSource of SoundManager has not been assigned.
You probably need to assign the audioSource variable of the SoundManager script in the inspector.
SoundManager.Start () (at Assets/SoundEffectsCoin.cs:11).

I am trying to add a sound effect on an object, but when I play the game, it is not there

[hot wave]

maybe it is positioned in x and y, then divide by 1.5, which is why it gets smaller if different number? (x/1.5f, y/1.5f, 0). it is in x and y

[calm coral]

It says you didn't assign a sound in the inspector

[acoustic sun]

Yeah, that is what I have been told. I did

I added the sound effect on Audio Clip and also created a script with it. I guess it is a script issue

[calm coral]

Show us what's on line 11 in SoundEffectsCoin.cs

[cobalt creek]

thank, i guess that makes sense. I found it hard to wrap around my head that this also is the spacing when x and y both go up from 0 1 2 3 4 regardless of 1.5 or not

bevause i set size var to 4 and doesnt change during runtiem

[hot wave]

ah, hmm but i dont know how to fix

[calm coral]

Where do you assign boingSound ?

[cobalt creek]

perhap something like using spacingX and spacingY will make that mroe clear for me instead of explicit value

more

[hot wave]

int size = 10; // Number of grid units in each dimension

for(int x = 0; x < size; x++)
{
    for(int y = 0; y < size; y++)
    {
        float offsetX = (gridSize / size) * x;
        float offsetY = (gridSize / size) * y;

        GameObject gu = GameObject.Instantiate(
            gridUnit,
            new Vector3(offsetX, offsetY, 0),
            Quaternion.identity,
            GameObject.Find("Lobby").transform
        );
    }
}``` can you try this, ah but not sure if working xD

[acoustic sun]

I'm not sure where to assign it. I wanted to assign a wav file on the script. sfx-boing.wav , spefically

[cobalt creek]

thank! maybe also it just a code clarity issue .. that looks like a good way to write it

[calm coral]

You assign it in the Unity inspector

[hot wave]

If you find anything about the code, tell me ok I want to learn it also

[acoustic sun]

How do I find Unity inspector?

[rich adder]

https://docs.unity3d.com/Manual/UsingTheInspector.html

[foggy lion]

Ugghh

[calm coral]

It's the same window where you have assigned SoundManager script

[foggy lion]

Everything is working, except for the one thing that isn't

my brain aches

[acoustic sun]

So from what it looks like, it is already opened

[calm coral]

Send us a screenshot of your inspector

[calm coral]

You can see audio source is not assigned

[acoustic sun]

Do I add that sound to Audio source instead or do I set it to both Audio Source and Boing Sound?

[cobalt creek]

your script works, thank! i tested it and adjusted the offset and the tiles outputted really nicely

this probably useful if someone making a word search or something

[queen adder]

        public static void AlphaChange(this SpriteRenderer sr, float alpha)
        {
            var col = sr.color;
            col.a = alpha;
            sr.color = col;
        }```is there better way to do this?

[teal viper]

Is there a problem with this method?

[queen adder]

not really just hoping theres a better way :3

[hot wave]

ah, I dont what it means I havent tried sprite renderer

[rich adder]

if it ain't broke..

[acoustic sun]

So I was able to assign it to coin, but I am still not getting any sound effects from it

[queen adder]

most likely because your AS not playing the clip, you need to do cs AS.PlayOneShot(AC);

[acoustic sun]

Where do I add this? In the script? Which line?

[queen adder]

in the play line

change the play cause it just play whatever is in the audiosource (which i think is currently empty)

[formal arch]

im firing off projectiles using a weapon script, it's fired off using an input (mouse 1), im trying to create a turret like assist for the player that will also fire off when they are firing, using the same function that the weapon uses to fire. the function takes a transform parameter so it knows where to spawn the projectiles, the issue im having is only one is ever firing at one time, when I want both of them to fire together, they are currently both running the function off the mouse 1 input

}

[foggy lion]

Down 0.5 Units every 2 seconds

[keen dew]

• Don't multiply forces by deltatime
• Check the value of speed
• Forces should be applied in FixedUpdate
• If you use transform.Rotate it'll mess up the physics collisions

[foggy crypt]

It worked
Thank 🙂

[astral igloo]

Hi do all components have reference to its gameobject and transform (like when we say this.gameobject or this.transform) or do they call getcomponent<>() behind ?

[eternal needle]

youll probably want to introduce some custom collision detection then, although sorry ive never made such a game i cant really suggest much. simplest way would likely just be checking the positions an object is moving to. assuming the grid data is stored in some array

[eternal needle]

accessing the transform doesnt use get component, and also the game object is not a component so that one doesnt really make sense

[astral igloo]

cool! thanks

Hey, I have a FSM Manager with a function NextState(); that invokes the method dinamically based of the current state using Reflection. How can I make it so that NextState() Invokes coroutines in other files? Here's the code: https://pastebin.com/UP0w42Wn

[eternal needle]

🤔 why do you need reflection here in the first place? is this AI work

[fair steeple]

iirc I got the script from a video which could have been ai

[eternal needle]

ditch the script, this is garbage

[gaunt ice]

you need the instance of other class

i dont think reflection can search it for you

[eternal needle]

dear lord i just looked closer at what the reflection is doing, using the enum state name then adding StateStart to it

use an abstract class for your state, then each child class (the actual states) will override a StateStart method. This way you can call any StateStart method without all this fluff

[gaunt ice]

or use interface, though abstract class is much better

[fair steeple]

Thanks, I'll look into that, I remember trying to do something like that before

I barely knew the first thing about programming so I ditched the idea when trying to figure out what abstract meant lol

[eternal needle]

to answer your question also, yes you can start a coroutine on another class. It will be much easier to do when you have the actual instance of the State

[fair steeple]

But I have the state files in a game object and a reference to them, isn't that an isntance?

[gaunt ice]

it is a text file

the component on your object is the actual instance

[fair steeple]

like this?

[gaunt ice]

yes

[eternal needle]

the fields you have

public WalkState walkState;
    public CrawlState crawlState;
    public DieState dieState;

are where you would store the actual instance. except the type would just be of the abstract class (or interface) like
State whateverNameHere

The space button isn't working as a jump in my code, but the WASD keys are working just fine?
Doesn't seem to be a coding problem from what I can tell so not sure why its not working.

[keen dew]

Do you get the log message?

[gray elk]

nope
I only get it when i can visually see the jump which is extremely few and far between

so hypothetically it works but not all the time, so I'm not quite sure what's preventing it from doing so all the time

[keen dew]

Probably the ground check then. Try removing it from the condition, if it works consistently after that then that's it

[gray elk]

that works, but i don't want double jump enabled.. is there any workaround?

[keen dew]

That wasn't meant to be a fix, you have to first identify the problem before you can fix it

now figure out why the ground check doesn't work and fix that part

I don't use the CC but check that you don't have any extra colliders etc

[brazen rivet]

I'm using some code to get the difficulty of the game using a little formula (infinite mobile game). For some reason, it is returning NaN.
difficulty = ((1/200)*Mathf.Pow(numSpawns - 70, 2.2f)) + 100;
Where numSpawns is how many times the 'enemies' have spawned.

[ashen adder]

Wdym?

[north kiln]

Exactly what I said. Read the bot message.

[ashen adder]

So all I have to do is just download one of those?

[teal viper]

Are you sure you're getting the error on this line? Can you assign the Pow part to a local variable and debug the value?

[north kiln]

No, you need to follow the instructions relating to the one you have installed.

[ashen adder]

Okay thanks!

[keen dew]

numSpawns is less than 70

[brazen rivet]

That would make sense, but when using the same formula on Desmos I get a continuous graph with no gaps

ie it's always defined

Is there a quirk with unity where you can't use powers with negative numbers?

[keen dew]

Good for Desmos, but Mathf.Pow expects a positive value there

[teal viper]

I don't think that's correct. It just raises the first param to the power

[gaunt ice]

this is math problem, non integer power of negative returns complex number

[teal viper]

You can raise a negative number

Unless I misunderstand something

[eternal needle]

Yea issue is with the float

[keen dew]

You can't raise a negative value to a fractional power

[teal viper]

Aah

I see. That makes sense.

[brazen rivet]

Ah I didn't know about that

Any idea how I could get the same graph without sitting around playing with desmos for another hour

[teal viper]

A fraction is kinda like getting a root, and you can't get a root of a negative number.

I think

[brazen rivet]

Yep that's right

[teal viper]

Is it critical to be able to evaluate x < 70?

[brazen rivet]

I think I could just play with desmos for a bit and find a similar looking equation

[eternal needle]

the exact same graph or just something similar? looks like a stretched cubic function

[brazen rivet]

Yep, pretty much that

I'll play around to find something similar

[eternal needle]

just replace the 2.2 with 3 then and mess around with the 1/200 then

[brazen rivet]

Yep

[eternal needle]

although it will get drastically different if you are using large numbers

[brazen rivet]

In the near impossible case someone gets that far

I'll just let it be linear at some point

[teal viper]

Can't you use an animation curve instead of hardcoded math?

[brazen rivet]

Never thought about that, I've never used an animated curve

Wouldn't that just be related to time, not how far the player has gotten?

[eternal needle]

do the animation curves let you extrapolate? i assumed you could only use it for a curve that you define values for and not an infinitely reaching curve

[brazen rivet]

I'll just stick to hardcoded math

Far easier for my small brain

And it's a very small game so it won't be something that bothers me later down the line

Even if it does, wouldn't be hard to switch systems

[teal viper]

Beyond the defined values, it would extrapolate linearly I think.

[vast sparrow]

I never codded in c# or any other language should I start with a less complicated language?

[languid spire]

C# is no more nor less complicated than any other language. Take a look at this
https://dotnet.microsoft.com/en-us/learn/csharp

[eternal needle]

theres no reason to really start in a "simpler language" which really just means python. I notice people who start with python often have difficulties transitioning to another language because of how unique it is.
I started in c# (if we can exclude my year of VB winforms 😄) and Im still glad my teacher taught c# first

[icy panther]

Yo guys, how do i get the range of two numbers in unity?

[stuck jay]

Python

[icy panther]

for example: 200 - 50 = 150
150 is the range between the numbers 200 and 50.

[eternal needle]

do you know what subtraction is?

[languid spire]

int x = a - b;

[tall delta]

I'm so confused... didn't you just answer your own question?

[stuck jay]

You just answered your own question

[icy panther]

no

because theres an issue

[stuck jay]

Post the code then

[icy panther]

the code wont check if the number is like say 200 - 300

it will return a negative

which is not what i want

[eternal needle]

get the absolute value of the number then (google how)

[languid spire]

then you want Math.Abs

[tall delta]

Mathf.Abs(x - y)?

[stuck jay]

Write an if statement to check which number is bigger

Or use one of the many methods that already do that

[icy panther]

would that give me the same result

[stuck jay]

Or you can just be lazy and convert the negative number to a positive one

[icy panther]

or will it be an incorrect distance?

[languid spire]

it gives you the Absolute (i.e. positive) value of the subtraction

[karmic flicker]

how do I get the verticies of the terrain to change the positions of the grass accordingly else this happens. any solutions ? Currently I am using constant Y axis value and random X and Z. with gpu instancing.

[icy panther]

alr thanks guys

yep it worked 🙂

[charred spoke]

https://docs.unity3d.com/ScriptReference/Terrain.SampleHeight.html

[karmic flicker]

oh thank you!

[teal viper]

I hope you're not gonna sample it every frame😬

[karmic flicker]

at start only

[ripe shard]

what kind of grass is this? particles? gameobjects?

[karmic flicker]

Mesh

billboard ones

[ripe shard]

so gameobjects?

[karmic flicker]

kind of yes

[ripe shard]

wdym by "kind of"?

[karmic flicker]

idk if Its gameObject caues I am not using Instantiate(); I am using Graphics.RenderMeshInstanced();

[ripe shard]

so its not gameobjects

[karmic flicker]

yes

[ripe shard]

anyway, by this method there is no shortcut, so everything is said... had it been particles you could have referenced the terrain data and have it sampled via vfx graph.

[karmic flicker]

One more question is there a way I can get the Terrain Layer / Texture at a point in the terrain to remove the grass from the sand part ?

[thin hollow]

how do i do a .getComponent to get an image
like i want to get that Image comonent

[languid spire]

do you have a reference to the gameobject or is the script on this gameobject?

[ripe shard]

This allows you to sample the splatmap(s) https://docs.unity3d.com/ScriptReference/TerrainData.GetAlphamapTexture.html, you have to calculate the UV coordinates you want to sample yourself afaik. Overall this should give you access to all the data you need https://docs.unity3d.com/ScriptReference/TerrainData.html

[pearl lodge]

Is there a way to change the color or alpha of a 'Tile'?
public Tile tile;

[languid spire]

please read the docs
https://docs.unity3d.com/ScriptReference/Tilemaps.Tile.html

[pearl lodge]

I tried this earlier and it was t working. I found a solution that I have to
use TileMap and give it the position of the tile, set its color flag, and then

use the TileMap give it the position of the tile and give it a color

I’ll see if I can change the color directly referencing the Tile. Thank you.

[thin hollow]

i have a reference

[languid spire]

then it's simply

Image image = refToGo.GetComponent<Image<>();

like any other GetComponent.
just make sure you have the correct using statement for the Image class

[thin hollow]

ok

thx

[earnest basalt]

is there a way to highlight specificmesh rendererer but without creating instanced materials (without highlighting meshes that use the same shared material)? maybe with resource blocks.. the reason i dont want instanced mats is because i usually keep forgetting to replace them with sharedmats when im done highlighting but maybe ill just need to do that

[verbal dome]

You can swap the renderer's sharedMaterials array. This will not instantiate materials, while materials does

I mean change to a completely different material while highlighted

[queen adder]

anyone made a grid checkbox system before? Like ruletiles, but probably larger

for tilebased movement something

like this

in inspector, is it hard?

[waxen cypress]

probs just a simple answer but im making like a vinyl player and its as simple as making an event for each like "disc" that activates music when played ye?

[verbal dome]

There is GUILayout.SelectionGrid, but you probably meed multiple selections at once?

You could just draw a bunch of buttons tbh

Or toggles with button style

[queen adder]

can information be saved to an SO?

it's for movement of pieces thingy

[verbal dome]

Only in the editor really

[queen adder]

uh so i cant use it?

[verbal dome]

If you need to save the SO in a built game, then no

What exactly do you need to save?

[teal viper]

You can create new SOs, and serialize them in json or something

New instances

[queen adder]

i mean i just need to tell that my archers can attack in the square 2 box away from center

then lancers can attack in a + shape

[verbal dome]

Ok but does that change during gameplay?

[teal viper]

But those included in the build are immutable (or rather, not gonna persist through the sessions)

[queen adder]

while being able to just check check thingies if they needed

like in ruletiles

[queen adder]

no

[verbal dome]

You mentioned saving so I thought you wanna change the SO while playing

[verbal dome]

Then its ok. You can read from the SOin a built game

And yeah can make instances of SO too if needed

[queen adder]

uh the quesation main is: is it hard to make 5x5 of this

but just true or false

[verbal dome]

5 rows of 5 toggles

[silver phoenix]

thx! :D

[low flint]

hey guys where do i go to for help with scripting camera movements? i dont want to be in the wrong place

[verbal dome]

GUILayout.Begin/EndHorizontal for each row, GUILayout.Toggle for the buttons

Can use the string "Button" as the guistyle parameter in Toggle

ok so i have never used unity before and for an assessment i have to make a rollaball type game. i want to make the camera follow the player (a ball) but when i find a script online and use it, it doesn't work as i need it to work. i tried using ai to fix it up but it doesn't do it properly. been trying for the last two hours but couldn't figure anything out so i came here. i also installed something called Cinamachine and tried to use that but couldn't figure out how to do it properly.
my code https://hastebin.com/share/qerivofice.csharp

[languid spire]

we do not provide support for AI Code on this server but reading your question I think you need to spend some time learning Unity. !learn is the best place to start

[eternal falcon]

:teacher: Unity Learn ↗

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

[teal viper]

Assessment? School assignment or what?
Why are you tasked with it with 0 experience with unity?

[low flint]

bro its the teachers that expect us to know all this stuff

[teal viper]

Didn't they teach you or at least give you time to learn it yourself?

[low flint]

nope

[teal viper]

That sounds very fishy. I'd complain to the school administration for giving unreasonable assignments

[low flint]

they wont do anything

[teal viper]

That being said, I'm afraid we can't give you a complete solution. You'll need to learn and come back with specific questions, details on the issue and explanation of debugging attempts. Check #854851968446365696 for more on how to ask a question more effectively.

[low flint]

so what if i say i have a problem with my script. i wrote a script to follow the movement of a ball that rolls around but for some reason it wont follow properly. I have tried searching online for other people doing the same im doing but cant find it. here is my script https://hastebin.com/share/qerivofice.csharp
any thing i can do to fix this issue?

are their any other servers that help with unity stuff?

[languid spire]

problem is, it is very obvious that not only did you not write this script, you do not understand it either

[low flint]

i can kinda understand it

first getting services then defining what stuff is then the main stuff

[teal viper]

Assuming, you have everything setup correctly in the inspector, I'd assume the issue is with incorrect lerping.

[low flint]

yeah the target is Player1 height offest 3 and follow smoothness 0.1

what should the lerp be?

wait

dont tell me

i'll figure it out myself

[teal viper]

Check the docs for how to properly use lerp.

[languid spire]

Realistically, forget it, aint gonna work

[crimson ibex]

is there a cleaner way to do this ?

Vector3 moveDistanceV3 = new Vector3(
                raycastHit.point.x - player.transform.position.x, 
                0,
                raycastHit.point.z - player.transform.position.z
                );

[languid spire]

because Unity does not support Python code

[keen dew]

Vector3 moveDistanceV3 = raycastHit.point - player.transform.position;
moveDistanceV3.y = 0;

Whether that's cleaner is a matter of opinion

[languid spire]

pretty sure there are websites that can do basic Python -> C# translation

[visual hedge]

Hello there. How badly do Coroutines/IENumerators suck compared to async and how badly should I be willing to learn how to use async?

[languid spire]

that's like comparing chalk and cheese, both have their place and time

[visual hedge]

ohh... okaay. So async isn't like better better coroutine, right? I mean... coroutines aren't deprecated just because async exists?

[languid spire]

no, not at all, they are two completely different concepts

[visual hedge]

got you, thanks a bunch!

[twilit pilot]

better has some subjectivity but they share a lot of similarities, the concepts are closely related, and the implementation is closely related. In Unity they are both typically used to solve the problem of time splicing & concurrency, though tasks with async/await are much more powerful (but come with some extra complexities because of that)

In Unity you can get away with never understanding it and just fiddling with coroutines, in the "real world" outside of Unity it's a fundamental concept of C# and other languages, so I'd definitely recommend learning it

[visual hedge]

thank you

[kind lark]

Hi together. I tried something with the unity job system and have some questions. What is the correct channel for that? general or advanced or beginner? (i think it is more of a beginner question but related to the job system)

[ripe shard]

Still an Advanced topic imo

[obtuse axle]

Hello, i have a question about the camera and body movement, when i move the camera, the entire body moves to face where the camera is looking. Is there a way to move the camera without moving the body?

[languid spire]

that depends on your heirarchy setup and your code

[obtuse axle]

That's basically it

[languid spire]

So there is nothing in your code that directly references your Camera object. All I see is Controller.Move which, I presume, is a CharacterController attached to your player which will, of course, affect all children objects of that Player

[obtuse axle]

Oh i see so i have to either move the camera out of the player or put something in the script that manages the camera

[languid spire]

exactly, think about it, if you are sitting in a car and the car moves, do you move as well?

[obtuse axle]

Ooh yeah i see

[cosmic dagger]

Loop through the array, check each element's y-axis, and assign the target variable to the current element if its value is less than the current target's y-value. The one assigned at the end of the loop will have the lowest y value . . .

[obtuse axle]

Btw do you think using a RigidBody is better or a Character Controller?

In general

[languid spire]

In this case, there is no such thing as better or worse, it all depends on what best fits the mechanics you want to implement

[cosmic dagger]

There is no general answer, as it depends on the type of game and movement you want. One can make the same game with both types of controllers . . .

[obtuse axle]

Then is RigidBody harder to implement?

I tried using RigidBody on Godot once, i got traumatised

[languid spire]

you miss the point, you would not implement Pong without Rigidbody and also you would not implement Tetris using rigidbody

[cosmic dagger]

I have no idea the difference between Godot Rigidbody and Unity's version. I'd test movement with both controllers and decide which one feels/fits your gameplay better . . .

[wind raptor]

Question about when to use events/delegates vs references/polling. Object A changes its color based on Object B's state. Currently, A has a reference to B, and it checks B's state in Update and sets its color accordingly. Is there a point at which I should be concerned about this, performance-wise?

Or is it more of a best practices thing, where it's better to decouple things and use delegates for cleanliness?

[frosty hound]

It probably won't be a noticeable performance thing unless you're doing this across thousands of objects. It's more of a cleanliness thing yeah. If you suspect that the colour changes rarely, or based on something that isn't Update frequent, then you can just subscribe to an event on that object.

[wintry quarry]

an event will do nothing to decouple things here

But I would still use an event instead of Update for this

Object A will still reference B, in order to subscribe to the event

B will fire the event, without an explicit reference to A

So nothing changes about the dependency graph

[frosty hound]

(Unless you make it a static event that passes itself but that really depends on your setup)

[wind raptor]

I'm just a few days into even understanding events, so I wouldn't know how to implement that

[frosty hound]

It's probably not what you need, anyway. Keep with what you're doing

[opaque rapids]

imported Book of The Dead in a blank HDRP project and here's an error i got

[languid spire]

And the lines of code causing the errors?

[opaque rapids]

those codes and files came within the original asset

[languid spire]

so, show what they are, they were probably made for a different version of Unity and may no longer work

[languid spire]

how is that supposed to help? Use some common sense please

[opaque rapids]

what do you want?

[languid spire]

the 2 lines of code that are throwing the errors

[wind raptor]

Double click the error message to go right to the problem code

[opaque rapids]

am literally a beginner and i have no idea where and how those are

[opaque rapids]

already doing it

[languid spire]

read the error messages, they tell you exactly what and where

[opaque rapids]

i am not a coder, i do not know how to exactly fix them

do you want me to paste the codes in here?

[languid spire]

I want you to show me exactly those 2 lines of code mentioned in the error messages

[opaque rapids]

ok, lemme try finding them

[languid spire]

this is the code file, the line number is 19. Do you understand this?

[opaque rapids]

yes

[sterile loom]

stupid question but is there anyway I can keep a frame by frame animation, but change character armor/helmet/boots/gauntlet?

something like a composite sprite where I only use the "naked" character and put layers of clothing on top of the animation through code?

[frosty hound]

Yes, just animate the sprites individually and change the sprite on the SpriteRenderer. As long as the animation is only moving things, you can put whatever sprite you want at runtime on the component.

[sterile loom]

mind if I message you directly? completely new to unity and im trying to understand this more

[frosty hound]

Or, if you want to animate only a nude character, you can use code to snap a separate sprite object to it.

I don't do DMs, sorry

[sterile loom]

all good i guess ill just ask here then.

[sterile loom]

this one, i think this is closer to what i have in mind

so I have to make the objects/sprites as a completely different thing right? i wont merge them to the old nude character sprite like on this vid? https://www.youtube.com/watch?v=tdTfgo9_hd8

basically what I have in mind, is banner saga's smooth 2d animation but I can change the character's clothing

[frosty hound]

The way you could organize it is have a character made up of multiple child object containers (head, body, arm_left) and animate those containers.

As a child of those container is the actual body sprite (nude) so that it follows.

As another child of those containers, and on a sprite rendering order higher than the body part is the clothing piece (so it appears on top).

[queen adder]

That's exactly what I do for my RPG^^^

[frosty hound]

MyCharacter (root object you actually move around with code)
  > Sprite (contains animator)
    > Head Container
       > Head Sprite (nude) | spritegroup: Character, order 0
       > Head Clothing      | spritegroup: Character, order 1
    > Body Container
       > etc.

[queen adder]

It seems like the guy ur watching is over complicating it IMO balforth

You just need to make child gameobjects for each customizable part of ur character and change there sprites at runtime.

[sterile loom]

let me try and visualize this from what im getting from you guys

[wind raptor]

Another vague-ish best practices question. If a script will for sure only ever have or need a single instance, is there a good reason not to implement the singleton pattern for it?

[frosty hound]

Nope, use a singleton and make your life easy

For example, managers or even the player in a non-multiplayer game are great singleton candidates

I also use them on canvases in a root scene. GameplayCanvas, DialogueCanvas, etc.

[wind raptor]

Yeah these are canvas/UI scripts I'm working with here. Mkay, thank you

[summer stump]

Will other scripts actually need to reference that single instance?

Ah, nevermind

[sterile loom]

@queen adder @frosty hound like so?

[queen adder]

Yeah

But there On top of each other

[wind raptor]

As a follow-up, any reason not to make all member variables/methods static? So that I can just access a function as MySingletonUIScript.ButtonState as opposed to MySingletonUIScript.Instance.ButtonState

[queen adder]

Or more so on type of the nude body

[sterile loom]

and I can still create separate animations for those individual sprites right? like moving clothing etc

[queen adder]

Yuh^^^

[sterile loom]

how would I determine the clothing layers tho? or will whichever comes first on the code be the one at the top?

[queen adder]

SpriteRender.Layer

You can change that via the unity editor inspector. Higher layer means it appears on type of anything with a lower layer number

[queen adder]

Anything that's static you can't access via the unity inspector other than that I think it's fine

[sterile loom]

ill do a test when i've finished the animation for the idle animation and see if I can swap around the clothing

thanks for the help 😄

[queen adder]

I tend to lean more towards static events for my UI or just have my UI listen for everything else

[wind raptor]

Okay, sorta back to my earlier question from before... I recognize that I'm very much in the weeds right now and won't notice any differences between the two implementations, but I'm just wanting to get some best practices in place.

Say object A has an enum state, and a color changes based on the state. The state and color are both members of object A. Is it better to check if the state has changed and then use a switch statement to change the color, or am I fine just skipping the state change check and setting my color in every Update loop (though it will almost never be changed for any given loop)

[cosmic dagger]

static members only exist on the class and not each individual instance. that's a big difference. also, they do not appear from the inspector . . .

[queen adder]

If objects A's color changes state and the state determines the color... then yeah just a normal switch statement is fine? It doesn't have to be in update? Who's changing object A's state and how?

[ashen adder]

anyone know a fix to this?

[wind raptor]

How the state changes isn't relevant I don't think. It's more a question of whether I should only update the color at a state change or if I can set it every Update.

But yeah I get your point that I can just tie the color change to the state change.

[queen adder]

How the state changes is relevant for sure. If ur just accessing the enum field I would have some sort of get and set that also changes the color when accessing the field

I typically have a method just called ChangeState() and when a state changes for a specific class I raise an event or update the rest of the class some how

[fiery badger]

Hi guys, I want to ask what does the "?" in the code do?

[queen adder]

A different script has the error

[summer stump]

Null check

[ashen adder]

Which one would it be?

[autumn tusk]

ok this is kinda weird

[queen adder]

Look at the error it tells you

You can also double click it and it will take you to it

[autumn tusk]

why does ontriggerstay only activate while the player is moving

[ashen adder]

Yeah thats what I did and it sent me to line 26 on that script

[autumn tusk]

i have a series of weapon pickups, and theyre only detected when collided with

[summer stump]

Is it 2d?

[autumn tusk]

yep

[summer stump]

The rigidbody may be sleeping

Be sure to change it to always awake

[autumn tusk]

yep, that fixed it

sweet

[queen adder]

Oh I'm stupid

The error shouldn't be on line 26 it looks like Line 16 is ur problem

[ashen adder]

What would the problem be?

[queen adder]

Ur passing in the wrong type

[ashen adder]

Sorry Im really new to this what do you mean?

[queen adder]

The method ur calling

MovementStateMachine.ChangeState()

Doesn't take movementState.IdleState as a argument

Also ()(); is invalid syntax

!ide

[ashen adder]

So what should I change it to?

[queen adder]

Show me ur current code please

[queen adder]

It's saying the argument should be of type GenshinImpactMovementSystem.IState

Is the PlayerStateMachine supposed to inheret from IState?

[ashen adder]

Yeah

[queen adder]

Could you share the code for that?

[ashen adder]

Actually my mistake it shouldnt

[queen adder]

Are you following a tutorial?

[summer stump]

Then it should not go in that function

That function expects IState

[queen adder]

Yeah lol

That's why I'm asking because you said yes then said no so I'm guessing you rewatchd a video

It's supposed to inherit from IState for sure

[rocky canyon]

this is oddly satisfying

[vagrant lynx]

Do you use animators or blend trees or just use script for handling animations

[woven crater]

i tried to modify the rotation parameter in the shader graph but it doesnt work?

[swift crag]

the name is wrong

click on Rotation here

then look in...was it the Graph Inspector or the other one?

[woven crater]

Reference name?

[swift crag]

Graph Inspector -> Node Settings

Yes, you want "Reference"

[woven crater]

ah i see thank

[swift crag]

so, in your case, it's probably _Rotation

The default is to add a leading _ and to replace spaces with _

"Total Damage" becomes _Total_Damage

[woven crater]

i see i see

[vagrant lynx]

I saw a guy on YouTube saying that, stop making webs on animators and instead use this, he showed that
animator.Play("")
thing to handle animations
Well, should I use this for 3D games and movements ??

[rocky canyon]

personally i use blend tree's when i can

if its a simple state/machine type anim setup i use code

[swift crag]

I think it's a good idea for situations where you unconditionally play an animation

[gaunt ledge]

okay... specialists of unity, I like to organize some of my components in diferent objects, like, a object specific for visuals, and a object specific for sound inside the main object, but many of them are empty, how much does a big amount of empty game objects can affect my game?

[swift crag]

Or for when the conditions for the animation are hard to express in the animator controller's state machine

[rich adder]

everything has a cost but its prob too small for you to notice

[vagrant lynx]

Okay

[gaunt ledge]

but if like... we are talking about the fact that I need up to 100 of those things spawning?

[queen adder]

As long as u dont plan for a mobile release it's probably fine

[summer stump]

What do you consider a big amount? Like a thousand?

[rich adder]

100 is nothing

[summer stump]

Eh. Should be fine

[gaunt ledge]

ahhh, okay then

thanks

[vagrant lynx]

Can we make blends between animations with scripts like the animator one?

[queen adder]

Animator.Play() is fine but you lose transition options and visual scripting which is what Animator is really for. But for a simple game it's fine

[vagrant lynx]

Hmm ok

Well, is it good to make movement and animation controllers in one script ?

[rich adder]

I would personally sperate them

[cosmic dagger]

As long as they're not being moved or their position is being updated individually, you're fine . . .

[queen adder]

I seperate them to

It logically doesn't make sense to me

[vagrant lynx]

Okay then

[queen adder]

And makes the classes harder to read and understand IMO

[vagrant lynx]

I'm separating them too

[summer stump]

That might be fine. But then you might end up with animation being handled in the movement script, AND an attacking script, AND some interacting script, AND AND AND.

Best to separate as much as you can

[gaunt ledge]

most of them have audiosources, and are moving as Sons of the main one

but not individualy

but the audio sources would stay, I just don't wanna have all of them in the same object

Gets kinda confuzing to find a specific audio

[cosmic dagger]

Keep them separate. Movement is not the same as animation . . .

[proven herald]

is there a way to prevent rigidbodies from merging child colliders with self?
i have a rigidbody with a collider, and I want a bigger collider to use as a raycast target but also want to use the main collider for physics

[rich adder]

layers

[queen adder]

There's two ways you could do it off the top of my head

Layers or Physics.IgnoreCollision()

[proven herald]

Is there a way to ignore collision with all colliders at once?

Seems like it works by pair?

[queen adder]

Layers then

[proven herald]

They are already on layers, what's the next step?
Not quite sure what that means

[cinder crag]

idk why the goggles and abckpack just acting weird , last time i did this , it was working fine but idk why the goggles and backpack seem to rotate ig? idk it seems weird

https://paste.ofcode.org/s8psarVmq9te9gQHHzcSWR , moveCamera script

[queen adder]

Put them on separate Collision layers

[proven herald]

oh COLLISION layers, hmm

[queen adder]

And inside the Inspector you can tell them what collisions to ignore via the Collider2D component

[cinder crag]

https://youtu.be/f473C43s8nE?si=dsqEdurxnVwMR5xQ i was just following this tutorial , i did it before and it was working fine but now they jsut actting weird af

[cinder crag]

like the goggles go under the capsule and the backpack distances away from the capsule a bit

[queen adder]

Sounds like a pivot point issue

I believe you just need to make separate gameobjects that will hold them in place

[spiral narwhal]

How would I have a game object move towards a target B from a starting position A, following a strict path, instead of moving exactly towards the target like done in Vector3.MoveTowards?

Would I have to implement A* or is there a different solution more adequate?

For more context, this is supposed to be for a tabletop game where the figures move between different nodes on the game board. The curved path is supposed to simulate the natural movement one does when moving figures around in real life.

I also thought of beziers, but then I'd have to define each node individually for each pathway, right?

[hidden lotus]

i have a question is 8.5 a float or a double?

my instinct tells me its a float since surely it doesnt occupy that much space in memory

all i did was convert the float '8' to 8.5 and it generated this error

[eternal needle]

Instead of guessing, type it into your IDE and let it tell you what type it is

Did you read the error? It's quite clear

[hidden lotus]

how is 8.5 a double tho

[spiral narwhal]

Floats use the f suffix

[hidden lotus]

well I did but i assumed there must be something else thats wrong

[timber tide]

if it's a defined path then beziers, or node traveling with interpolation

fyi you can do it with the animator

[spiral narwhal]

With the animator?

[timber tide]

yep, can use that to travel on curves

[spiral narwhal]

Oh a manual animation for each path?

[timber tide]

interpolate between nodes, yes

[spiral narwhal]

Sounds like a nightmare to manage in the long run I think

For example, if a path changes

[hidden lotus]

like this???

[spiral narwhal]

Not very maintainable

[timber tide]

if it's a defined path, then you need to do it manually somehow

[spiral narwhal]

Yes that's a float

[keen dew]

It's not a question of how big or how much memory it takes. A number with a decimal point without the f is always a double

[spiral narwhal]

Wouldn't pathfinding automate this somehow?

[timber tide]

if you want pathfinding then you do A*

as it will find you the shortest path

[hidden lotus]

well i still get an error in the same spot depsite there being no red

[eternal needle]

You didnt save

[hidden lotus]

im acc so stupid

[hidden lotus]

yep thank you

[spiral narwhal]

The same thing is also the case with long values btw.
If you want a long instead of an int, you must use l or L (preferably L because l is easily confused with 1)

Basically, you need to tell C# which value of the same literals you want (15 could be both an integer and a long integer, so there must be some kind of way to differentiate both)

[spiral narwhal]

Mm yup thanks

[hidden lotus]

oh

[spiral narwhal]

Always wanted to try out Unity's pathfinding package so maybe I'll use this opportunity and give it a shot :D

[strong willow]

I jus started unity im confused when i change the scale of an object it doesnt change a green out line apears this never happend before in my previous attempts in learning unity

[hidden lotus]

i assumed that instead of saying a prefix for float/double, i specify if its a double or float at the begining like in standard C

[queen adder]

It's the same way in C?

[spiral narwhal]

I haven't worked with C in ages but I'm like 80% sure it also uses the f suffixes

[hidden lotus]

i've never had to use them so i dont believe they exist lol

[queen adder]

Believe it or not but C# borrows alot from C

[spiral narwhal]

Like the compiler has a typing stage, where it must assess which type the literal has

[zenith cypress]

It seems f is optional

[queen adder]

The syntax is the exact same

[hidden lotus]

that is crazy i never knew that

so c# just forces u to specify

[spiral narwhal]

C# has many of these pre and suffixes. For example, "@" will allow you to name a member after keywords

[hidden lotus]

whereas c doesn't

[queen adder]

As it should

[zenith cypress]

Ah I see, C has an implicit cast from double to float, C# doesn't

[wintry quarry]

That's the only difference^

Showing once again that C is very happy to let you do potentially dangerous things without complaint

I bet depending on your C compiler flags that may be an error under certain settings

[queen adder]

"It's ur fault ur code crashed bro. It's a skill issue"

[pallid nymph]

Pathfinding is for, well, finding a path... what you described sounded like you already have the path and just want objects to move on it which is not what pathfinding is for... so, which one is it? 🙂

[spiral narwhal]

C is considerably more weakly typed than C# / Java / etc

[spiral narwhal]

Definitely the latter!

The thing is I wanted to prevent having to redo anything if the path changes in later stages of production

[timber tide]

replace java with c#

[pallid nymph]

So, instead of having one target point, have a list that you adjust... and you can add some curve-thing that makes it smooth if you want

[spiral narwhal]

Mmm, I honestly have no idea how that would work and look smooth at the same time

[pulsar flame]

null check

[spiral narwhal]

Lmao that was high above for sure :D

[pallid nymph]

Well, if you want to find a path, you need a system that defines where you can move and all that, and on top of it find a path... and there's a single one by definition... so definitely no pathfinding 😄 pathfinding itself usually uses a graph and it finds a path on it to reach from A to B... it doesn't try to be smooth or anything, just finds a path

[pulsar flame]

sorry... i looked and saw that first

[zenith cypress]

In that case, ?. does a raw null check, which is why it isn't advised to use it for unity objects (no idea what that function returns so just random trivia)

[spiral narwhal]

I think it's because ?. is not overloaded by Unity

[spiral narwhal]

Yes you're right that's not the way to go

[pallid nymph]

I'm not entirely sure what you have in mind (like what kind of game it is and what objects are gonna be moving, and are they gonna be moving all the time or just from one spot to another)... but all in all - you define a path by points, and if you want it smooth, you use some curves 🙂

[zenith cypress]

It does a raw null check, you can't overload ?.

[spiral narwhal]

Sounds like using animation sets might even be preferred

Thanks for the help ^^

[timber tide]

vs does throw me warnings on using ?. with monos

[pallid nymph]

the animator thing sounds super weird, but am no expert

[timber tide]

but null checking via comparison operator still works

[wintry quarry]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/member-access-operators#null-conditional-operators--and-

Look it's the little known ?[] operator!

[zenith cypress]

Yeah ? by itself is literally just an if statement (var foo = a ? b : c;)

[timber tide]

though, checking if monos are null isn't that useful if destroyed on the same frame

[wintry quarry]

nobody here has ever used ?[] I guarantee it

[fiery badger]

I see thanks

[timber tide]

usually I'm always using them for events because why not

[pallid nymph]

it's kinda the norm for events (if you mean doing ?.Invoke)

[spiral narwhal]

Rider actively admonishes you for leaving out ?. in events :D

[timber tide]

yeah, I think vs does recommend it too

[faint sluice]

Wait so you can use ?. To check for static instance/singletons too??

[wintry quarry]

You shouldn't use ?. with anything derived from UnityEngine.Object at all, which would be most singletons in Unity.

otherwise yes you are free to use it with any reference you want.

[faint sluice]

Haven't been doing it so far :]

[spiral narwhal]

I'm struggling to find a reason for having singletons that can be null though

[faint sluice]

Only for events and actions

[pallid nymph]

I'm 10% considering adding some extension method that converts fake nulls to true nulls so that I can use ?. moar

[faint sluice]

Just came in mind and i blurted it out, don't booly me 🥲

[zenith cypress]

public static T OrNull<T>(this T obj) where T : Object => obj ? obj : null;

[timber tide]

well, if you don't use ddol then you can have null singletons

so it makes sense

[spiral narwhal]

ddol?

[timber tide]

dont destroy on load between scenes

[spiral narwhal]

That abbreviation tho haha

[summer stump]

That is the standard abbreviation
I think it's even in the docs

[spiral narwhal]

🤷‍♂️

[zenith cypress]

Pulling from elsewhere where I posted about the difference with implicit/operator/?.. Kinda interesting

[pallid nymph]

exactly, just not sure I'd actually use it or would I consider the code getting too ugly just so I can use ?. 😄

[stuck jay]

Where C# on that graph

[rich adder]

put script where animator is

what i do though is make a seperate script just for a Unity Event

then listen to it from whatever script I want anim event from

[stuck jay]

How to ignore error messages like "UnassignedReferenceException: The variable damageDealer of Health has not been assigned."?

[frosty hound]

You don't, you fix them

[stuck jay]

There's realistically never going to be a situation where this function is triggered while damageDealer is not set, and even if it does happen nothing would break

[queen adder]

You cant run the game without handling the NRE lol

[stuck jay]

Nope, this error only runs when the game runs

[rich adder]

You can , doesn't mean you should

[frosty hound]

Then put a null check before you attempting to use it, if you think it's not a problem

[stuck jay]

Hahaha that's the thing... I can't find a documentation on how to apply the (?) null check to this line

 LevelSystem damagerLevelScript = GetComponent<Health>().damageDealer.GetComponent<LevelSystem>();```

[frosty hound]

Wrap it in an if statement

[rich adder]

!= null

? will not work on UnityEngine.Object

[shell sorrel]

also seems weird to GetComponent to access a other component, so you can GetComponent again

[rich adder]

def a design issue somewhere

[crisp copper]

what do i need to do so i can sprint?

[rich adder]

first of all instead of crossposting and ignoring what I said, configure your IDE first. its part of the rules

[shell sorrel]

but yeah all UnityEngine.Object stuff you need to use equality operators to check null cant use ?. and ??

[stuck jay]

I access another component that keeps track of which game object dealt the damage, then access that game object to get its LevelSystem.cs script

[shell sorrel]

yeah sorry without context i thought you were literally storing code in a word doc. but yeah PraetorBlue gave you the info you need

[summer stump]

Disagree, but why would you paste pictures either?

[rich adder]

Debug.Log(somethingIwantToCheck)

need it for school coursework

[wintry quarry]

Use Debug.Log or attach the debugger

inspect each thing that could potentially be null. See which one is

[summer stump]

Can you not share the file itself?

bro im not tryna spam istg

[wintry quarry]

We were asking you to share your code, that is the guide for how to do so

[wintry quarry]

There is no such limitation, it is likely an issue in your code or your scene setup

[summer stump]

That command brings up a bot. You are supposed to READ the message and follow those instructions

Show the code you have using the process described by the bot

[strong willow]

can i do it one more time to propperly read it

[summer stump]

No

[shell sorrel]

just scroll up

[summer stump]

[shell sorrel]

like ffs

[rich adder]

is scrolling up diffcult ?

[summer stump]

I just scrolled up, copied the link to the bot message, came back down and posted it for you to make it even easier 🤷‍♂️

[olive hornet]

I was trying to find the issue, I checked the layers and the colliders, everything seems in place. If I move the camera in order to be closer to the same spot that is not being detected, it starts to be detected. As if the raycast angle diffence to the colision point normal is affecting it. I'll try to check everything again. Thanks!

fedleon has been warned.

istg im not trolling

[summer stump]

Arguing with the mod is a real bad idea. Just share your code so we can help or leave

If the next thing you do is anything other than sharing code, I think you may be muted or banned

idk how even with the bot im confused whats a backquote

[summer stump]

Use a paste site (listed at the top)

[rich adder]

wow imagine that

a tool that actually gives answers!? amazing

[strong willow]

bro shut up

u think i didnt search

[summer stump]

Oof. Alright, I'm out

[strong willow]

nvm imma jus help my self

[shell sorrel]

`

[rich adder]

yeah maybe you learn something by squeezing the brain a bit

[strong willow]

stfu

[shell sorrel]

no reason to antagonize

[strong willow]

and yet im the troll

[cobalt creek]

so i have grid of squares where the number is part of the GO name:
012
345
678

So it easy to tell that if i add one, it mean i can reference the next value as long value 0 or 1:
int goRight = index + 1;
However, how do I now what value to get of diagonal or up/down? It not easay to tell that the lower right diagonal is 4, eg

int goRightDown = index + ???

[proven herald]

I have a prefab that has rigidbody, collider & a few scripts attached, plus a health bar as a children
I'd like to use different prefabs for the "model" & collider within it while keeping everything else the same, what would be the better way to do this?

I've been at this for like an hour, there's always something new that breaks

[gaunt ice]

please use 2d array
or row_idx * column_length + column_idx for flatten 1d array

[strong willow]

man i was jus askin for help and i was the one getting insulted

[rich adder]

telling you search something you're confused on isn't an insult lol

If you don't push yourself you will not learn

[strong willow]

this?

plus im tryna learn

[fickle plume]

For the last time. If next thing you post is not related to your actual question you are out of here.

[strong willow]

and ur not helping

[shell sorrel]

would use 2d indexes then convert to the 1d as needed x + width * y is how you would convert a x, y coord to a 1d index

[cobalt creek]

thank, i guess that is good starting point, but thing is my grid is created before runtime, so won't I have to apply reference to already created, or get position value? because it arranged like this:

[strong willow]

nvm bro like i said imma help my self

[gaunt ice]

a easy way to go up/down is +column_length or -column_length

[cobalt creek]

thank, i guess that woudl work

[modest dust]

Simply have an array containing the models and colliders, and swap these out when needed (either have them on and disabled or instantiate/destroy when necessary)

[rich adder]

saying by helping yourself pushes the brain to learn is not an insult, thought it was a fair statement. Anyway I digress since Mod wants this convo done.. I shall not reply anymoee , Goodluck with your learning

[wintry quarry]

Are you sure it's not just the raycast distance? Where is the ray originating? What max distance is being used? How are you drawing the blue line?

[proven herald]

the models need to be within the root (parent) object part of the prefab though
how can i 'swap them out' ?

[crisp copper]

@rich adder am i done now???? or do i need to do enything else?

[rich adder]

👏

now you're coding Properly

[wind raptor]

I have a confirmation "popup window" ui element with a confirm and cancel button. I'd like clicks outside of the window to close the window/be equivalent to pressing the cancel button, and I'd like for other UI elements to not be selectable while the popup window is open. How might I do this without having a giant invisible button over my entire canvas?

[modest dust]

Simply have them anchored to the parent object (or make an array of prefabs and instantiate them as a child of the root object)

[crisp copper]

so can you help me now hov i make so i can sprint on shift?

[modest dust]

Basically separate the visuals and colliders from the root and have them as a child

[gaunt ice]

btw you cant just +1 to go right since you may go to next row
imagine index 2 + 1 = 3

you have to check

[twilit pilot]

separating them is fine, a hierarchy along the lines of this should work:

-- Colliders
---- Collider1
---- Collider2
-- Visual
---- Model1```

[rich adder]

ok post the script (not screenshots anymore)

[cobalt creek]

yea, I see now

[crisp copper]

@rich adder what will this help me whit?

[rich adder]

oh you mean the bot msg

[crisp copper]

yea

[rich adder]

need to see the script

[cobalt creek]

I guess there is also big benefit to assign row and colum nto each unit because then u can check if a rxc exists, eg if youre at 1x3 and diagonal (right and down) is 2x4 but that is out of bounds and my code should catch that

[rich adder]

already mentioned earlier how to sprint though

[crisp copper]

in the bot messeg it ses add a cs to the first line,
so i should add cs in evry scripts or what?

[rich adder]

nah you are posting an entire class that is def a Large Code situation

you send it via link

[rich adder]

also

[crisp copper]

wear?

[rich adder]

in the same place you capture inputs for movement

Update

[cobalt creek]

I guess one other way is to create the grid with the gird layout group etc. and other components that deal with the formatting automatically, then insert each unit at runtime and assign row and column programmatically (instead of get reference of each preexisting one which is more work)

[stuck jay]

@rich adder Don't think you ever judged this, still bad design?

[rich adder]

Dont just copy and paste it though, try to understand why its that way

[rich adder]

I dont know the full context and what those scripts even do though, also seems you mentioned a different script than what your GetComponet was

[summer stump]

I do the first part in my games (tracking who passed damage). I think the XPOnDestroy may be fine, it does introduce a kinda three way coupling, but if the health script is the intermediary (the one passing the message back to the damage dealer) it would be fine

[ashen adder]

How do I identify a Null and How do I fix It?

[rich adder]

We told you multiple times how..

[shell sorrel]

feel instead ofa XPOnDestroy would just have health invoke a event when it reaches 0, what subs can decide how to handle that

[ashen adder]

I still dont know mb

[stuck jay]

Wouldn't that make health.cs unusable though?

[rich adder]

You need Debug.Log eachh one of those things and see which one prints Null

[stuck jay]

For anything that isn't an XP giver

[rich adder]

it can only be those few things on line 55

[north kiln]

https://unity.huh.how/runtime-exceptions/nullreferenceexception

[summer stump]

Why?

[rich adder]

yeah i linked them there

they didn't get it either lol

Debug.Log(myObject1)
Debug.Log(myObject2)

or combine them

https://unity.huh.how/runtime-exceptions/nullreferenceexception/debugging

[stuck jay]

Some objects might reach zero HP without invoking an event

[summer stump]

Yeah, that is fine

TryGetComponent, if not XP then don't try to give xp

[proven herald]

oh wow, it was that simple, tyvm

[summer stump]

The event could just let the damage giver know the thing died, or just NOT do the event. It can be quite dynamic

[stuck jay]

So it's just another way to give XP instead of XPOnDeath.cs

I can't think of many scenarios where this would be better in a heavily-composition-dependent project instead of just slapping an XPOnDeath component, especially since I'm trying to avoid using noun scripts
