its a basic google serch 🤷‍♂️

Unity learn UI

[wild cargo]

Fair

[fluid kiln]

this kinda is a headache ngl cuz its a very specific case, like for the ui i need to use images, and for the game i need to use sprites.

[shrewd swift]

hey
do you guys put all your class vars together ? or do you split between the ones that are shown in the inspector and the ones that arent ?

[rich adder]

what does "using images even mean", You can put images perfeclty fine on ui..its not diff than sprite renderer..
anyway this is a coding channel. Further questions should go in #📲┃ui-ux

[rich adder]

i split my scripts between responsibilities

when i can..

[shrewd swift]

if you have one script, do you split or not ?

[rich adder]

nothing is public, only properties and some methods

[rich adder]

no , 1 script does one thing specific

[shrewd swift]

yeah same, but im wondering if im not losing time by making two diff blocks for the inspector

[shrewd swift]

i mean the vars

[lethal depot]

hii guys, i'm trying to make an enemyAI in which the enemy follows the player and attacks from range of 8 unit but it everytime rotates into different direction rather than facing player direction, i dont't know why its happening

[rich adder]

forgot about the inspector, thats just the editor

whats more important is how clean code is (and functional duh)

[rich adder]

can you show code also show your Pivots not in Global mode

and Center should not be selected, should be Pivot

pretty sure your Enemy is turning correctly

everything else as child is just parented to wrong forward

guaranteed xD

[lethal depot]

how do i fix that?

[rich adder]

make sure gun is parented to forward of Enemy

the correct one

In Local Pivot mode

[languid spire]

for gods sake use Debug.Log.
this direction.Normalize(); is nonsense

[lethal depot]

i was just trying to follow a tutorial , not my fault😫

[languid spire]

yes, your fault for doing so blindly without engaging your brain

Why does this happen Everytime I open a file in unity

It doesn’t let ke touch anything in unity and the loading doesn’t stop

Cam anyone help

[vast vessel]

How do i do multi threading to make performance better?

Or is multi threading just a thing that is there on all unity projects

[polar acorn]

The word "multithreading" should not be uttered in beginner code

[gaunt ice]

job system

[vast vessel]

Eh i just know it from trying to make gmod performant on my potato pc

[polar acorn]

Job system is what you would do but if you're posting here chances are your performance issues are not related to threading

Try using the profiler and finding out where the problem actually is

[vast vessel]

I dont have any extra if checks, or.. ehm ehm.. random empty update()s. I also tried to minimize garbage collection, whatever that even means

But my code has a large delay on my cpu

Also i use unitys object pooling for bullets and impact effects in my game

[polar acorn]

So check the profiler and find out why

[gaunt ice]

then write your own pool

[vast vessel]

Is the unity one bad?

[gaunt ice]

you said it is slow

[vast vessel]

I meant i did that to increase performance

[polar acorn]

Until you profile the game and find out what is slow, you are just guessing. Get some data, and figure out what can be done to fix it from there

[vast vessel]

Can jobs improve it tho?

Like, does it help?

[polar acorn]

Who knows, you have no information as to what the problem is

[gaunt ice]

first, can your code multithreaded? (moving rb can be multithreaded but modifying BVH/space partitioning not)

[vast vessel]

Lets sey there are no problems, can it make performance better by spreading the tasks between multiple cpu cores?

[vast vessel]

Whats a bvh?

[polar acorn]

If there's no problems then there's no performance to improve, you'll hit your target framerate and more performance won't actually change anything

[gaunt ice]

bounding volume hierarchy

afaik modification of any tree cant be multithreaded (at least it has to lock the whold subtree)

Hi everyone... https://paste.ofcode.org/32P9EH6DAxdKwKvL9X8Fr4h In that code i have three big methods in the end of the code, and i wanna move them into separated scripts to keep the organizacion of my code... my doubt is if you recommend me to move them into separated classes or into a partial one of the one they are currently in

I listen you all

🙂

[polar acorn]

If the functions are only ever used in this class then there's no reason to move them anywhere

There's a bit of repeated code you could probably extract into a method, like this bit here

You do code that looks basically like this but with different code in several places, that could be a function with those text strings as parameters, and you can call that function instead of doing this in multiple places

[dry tendon]

Yeah, but this three last big classes are going to be much bigger... and i think is not quite good to have 200 code lines into one script... isn't it? I don't know too much about clean code hehe, so i'd like to know what you thing about it

[dry tendon]

Hmm, true

i'll take a look to that

[polar acorn]

You'd still have 200 lines of code, just in multiple files. Moving the problem elsewhere doesn't make it any cleaner. Instead find repeated sections of code and make them into reusable functions with parameters

[dry tendon]

nice tip, thanks!

[desert elm]

so, this should find the component "Unit" for each gameobject that has its collider in this list

[polar acorn]

This code will loop over each object in explosionHits then set enemyHealth to the same Unit component in this script's object or its parent over and over again

[desert elm]

oh I misunderstood the documentation then- if I want to change a specific integer in the component, how could I do that?

[brazen cedar]

Hellooo

How can I make this folk move towards the object facing it?

[polar acorn]

You'd actually change that value instead of just getting the component

[desert elm]

and how could I do that?

[polar acorn]

With = usually

[desert elm]

I meant like- how could i find that specific value in the Unit component of a different gameobject?

[polar acorn]

You would get that component from that game object, instead of this one

[rich adder]

pretty sure replied this yesterday
#💻┃code-beginner message

https://docs.unity3d.com/ScriptReference/Vector3.RotateTowards.html

just set your player as target and ur done

just make sure the gizmos are correct in Local Pivot mode.

[brazen cedar]

And wouldn't I need to define a facing side for the object?

Okay

Thank you

ok np. try it out and let me know how it works out

Okay I will

 void Update()
    {
        horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;
        verticalMove = Input.GetAxisRaw("Vertical");
        if (verticalMove == 1)
        {
            jump = true;
        }
    }

    void FixedUpdate()
    {
        controller.Move(horizontalMove * Time.fixedDeltaTime, false, jump);
        jump = false;
    }

 void Update()
    {
        horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;

            crouch = false;

        //move the Character
        controller.Move(horizontalMove * Time.fixedDeltaTime, crouch, jump);
        jump = false;
        

    }

Following a tutorial and I want to get the jumping and crouching working on just the left analogue stick (trying to learn so it's applicable to fighting games) instead of buttons. For some reason when I try to use the y axis for jumping it sends me to space vs when I use the button jump it's fine (I'm using the Character Controller 2D script from the video, there is no double jump so it's not repeating the jump call when in the air)

Also using the dpad would be nice but one step at a time

[desert elm]

and I assume I can do that with GetComponentInParent
and the colliders are the colliders of other gameobjects

[polar acorn]

If you want to get a component in the parent of one of those colliders, call GetComponentInParent on one of those colliders

[desert elm]

right need to figure out what that is

[polar acorn]

What what is?

[desert elm]

calling

[polar acorn]

https://learn.microsoft.com/en-us/dotnet/csharp/methods

You should probably familiarize yourself with the basic terminology of C# before attempting to make anything in it

[desert elm]

oh its just methods-

[upper ember]

Have tried
Adding verticalMove = 0; underneath setting jump back to false (slightly better but still go to space without the fastest of taps on up)
adding jump = false; right after setting it to true in the if statement (no jump)
Using verticalMove >= 0 in the if statement (make problem worse)
Am also using a controller with a digital joystick so that the value should always be -1 / 0 / 1

[tender breach]

Now I'm getting an error that says, "Cannot implicitly convert type int to UnityEngine.Color", here's the code: https://pastecode.io/s/rd1h57ms

[waxen oracle]

What is a cinemachine camera? Im trying to learn how to transition between cameras and every tutorial says cinemachine

[polar acorn]

An integer is not a color

You are getting a random number between 0 and the length of your array. That's not a color

[tender breach]

How do I fix it via code?

[polar acorn]

You should probably set the color to a color, not an integer

[rich adder]

should use this https://docs.unity3d.com/ScriptReference/Random.ColorHSV.html

[slender nymph]

can you screenshot what that code looks like in your IDE?

[polar acorn]

Presumably they want a random color from a list rather than a simply randomly generated color

[rich adder]

Ah okk

[short hazel]

The random number you get is in range of your list, now access said list with that number to get an element

[slender nymph]

wow, i'm surprised it is actually configured with that horrible formatting

[tender breach]

Yeah

[thorn holly]

try
{
  triangles.Add(pyramidFormation[l][i].GetComponent<NodeBehavior>().index);
  triangles.Add(pyramidFormation[l + 1][i].GetComponent<NodeBehavior>().index);
  triangles.Add(pyramidFormation[l + 1][i+1].GetComponent<NodeBehavior>().index);
} catch (Exception e) {
  Debug.Log(e);
}

So I have this fairly simple code here, lmk if i have to show more code here, but im logging an error that Object reference is not set to instance of an object. I'm not too sure what I did wrong, again, lmk if i need to show more code

[rich adder]

you have to use the item from the array

which is the Color

[tender breach]

And how do I do that?

[polar acorn]

Why so many get components, just make the list of type NodeBehavior

[short hazel]

Wait till you see longer snippets. It's like that but on all the lines. No indentation, everything is packed up like that

[rich adder]

pass the index you get from random to the array

[slender nymph]

oh i know, i've seen their war crimes

[polar acorn]

Do you know how to get an element from an array

[tender breach]

I think so.

[polar acorn]

then do that

[thorn holly]

theres some other stuff I do with that list in other parts of the code, this isn't the only instance where i use the list

[polar acorn]

Do the other parts where you use the list involve you getting a specific component from it

[thorn holly]

yeah, transform

[polar acorn]

All components have a .transform property. Make your list of type NodeBehavior and use .transform when you need that

[upper ember]

The debug log shows that I'm actually never setting it to 1 if I tap it quickly enough though it still jumps too high, if I hold it and it actually sets to one in the debug I'm in space

[tender breach]

I did.

Look at the code.

[polar acorn]

Okay then show that instead of code where you don't do that

[thorn holly]

alright, I will. Do you know why theres an error though?

[tender breach]

https://pastecode.io/s/2xy5goxk

[polar acorn]

What line has the error

[polar acorn]

No, I said show one where you are getting an element from an array

This is the same code

[tender breach]

https://pastecode.io/s/utsfhfgn

[rich adder]

great you got the random Index, but where is the array element?

[polar acorn]

Okay, now show code of you getting an element from an array

[thorn holly]

the first triangles.Add()

[slender nymph]

what is example2 🤔

[tender breach]

I don't know how to do it!

[polar acorn]

Then either triangles, pyramidFormation, pyramidFormation[1], or pyramidFormation[1][i] is null, or it doesn't have a NodeBehavior on it

[polar acorn]

#💻┃code-beginner message
Then you should say that when asked

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arrays

[brazen cedar]

It seems it does, but only for a few seconds

[rich adder]

its correct

Your model however, is not

[jaunty lily]

does anyone have idea if its possible/hard to make a way, that the player is being recorded from a perspective while playing, the whole time? and that that video gets saved somewhere and can be shown at a given time? sorry if im unclear, im new

[brazen cedar]

How can I correct that?

[rich adder]

In Unity the Blue is forward

[rich adder]

put the Model on a child object and rotate to face the blue part

the code is working tho

[brazen cedar]

Just like that?

I will try

[languid spire]

very easy to do but the performance impact would likely be prohibitive

[rich adder]

yes in Unity, Blue arrow is the Forward of any object

also Don't use Center mode for pivot, use Pivot

you don't want weird issues later

[thorn holly]

looks like pyramidFormation[l][i] is null

[brazen cedar]

Done

[polar acorn]

Where do you set it

[thorn holly]

heres the code that sets it:

NodeBehavior currentNode = pyramidFormation[l][i];
currentNode = nodes[nextAvailableNode].GetComponent<NodeBehavior>();

currentNode is a reference to pyramidFormation[l][i]

[polar acorn]

So it'd seem that nodes[nextAvailableNode] does not have a NodeBehavior

This is one of the reasons you should be using that as your type for all these lists

It won't be possible to put something in the list that doesn't have a NodeBehavior

[thorn holly]

alright, I just made nodes a NodeBehavior list

[languid spire]

also that code makes no sense. changing currentNode will not change pyramidFormation[l][i]

[thorn holly]

it wont?

[polar acorn]

Ah, right, that too

[brazen cedar]

Okay so the child is looking towards the blue arrow of the father

[languid spire]

no , it wont

[polar acorn]

No, you're changing which NodeBehavior the variable currentNode points to

[brazen cedar]

Should I put all the logic in the father or ir in the same capy?

[jaunty lily]

could itbe that the game will lagg? im not planning to make a game with amazing shaders or anything like that

[rich adder]

all components except mesh go on parent, but you outta fix that pivot

[brazen cedar]

Since it's still facing wrong

[languid spire]

It will lag, making real time mp4 at run time is very, very heavy

[thorn holly]

ah

[tawny rain]

i keep getting this error when trying to run game what should i do?

[jaunty lily]

how does, fortnite do it for example? like the match replay? it just needs a recording of the gameplay from another pov

[slender nymph]

start by configuring your !IDE

[polar acorn]

What is myRidgidbody

[languid spire]

I dont know how fortnite did it, I didn't develop it. How I would do it is by using async threads with reduced fps if I even wanted to get close to it

[short hazel]

It records the positions of everything at a fixed rate, and replays them. It's less expensive than recording to a file, but would still produce a consequent file size, especially if you have a lot of objects in your scene

[upper ember]

Not sure how fortnite does it but if the game is determanistic you can just record the inputs and replay those as a script, that's how fighting game replays work

[desert elm]

this should do that, right?

[polar acorn]

This is exactly the same as your original code

You're still calling GetComponentInParent on this object

[copper locust]

you wrote it wrong in one you added a d in myRigidbody in the other one you didnt

[polar acorn]

Also there's nothing in your foreach loop you end it before you open the curly braces

[languid spire]

and that is supposed to do what exactly?

[jaunty lily]

it doesnt neccesairly need to be a file, i just need the gameplay to be shown at some point in the game, i could split it up, but want to reduce cuts at minimum

[jaunty lily]

interesting.. i could just make the 'fake player' re-act what the actual player did?

[languid spire]

no way you are going to be keeping an mp4 in memory without problems

[jaunty lily]

what do you mean?

[polar acorn]

Encoded video is big

[upper ember]

as long as the same inputs always create the same outputs it should work, idk I'm brand new but it seems like a simple concept - if there is any form of rng this won't work

[desert elm]

I am trying to get a reference to another component ("Unit") on each gameobject whos collider is on a list

[polar acorn]

Then get the component from that object

call the function on that

[languid spire]

do you have any idea the amount of space an mp4 will use?

[jaunty lily]

yeah im new aswell and im trying to figure this out, jus brainstormin :)

[sand veldt]

Can anyone guide me for animation on a character
My character has more than one walking style

so how can i set it to one random style when it spawn

[jaunty lily]

okay, yeah thats true, i guess ill need to make cuts, but itll still be big im guessing, could there be a workaround? or something else?

[desert elm]

I do not know how to get said GameObjects
as I only have their collider components in a list

[polar acorn]

You have them

that's what you're looping over

Use that

[short hazel]

The thing you record is stored in memory until you write it to a file for example. If you do nothing with it, it will accumulate, fill up your RAM, and your game will crash because it will be out of memory at some point

[languid spire]

Ok, so your code does not do that at all

[desert elm]

I am aware now

[desert elm]

oh okay
thought that this only got the collider components into a list

if it gets the gameobjects that makes my life easier

[polar acorn]

It does

[jaunty lily]

sooo, what if it writes whilst recording? lets say the output (the screen of the recording) will just be playing while recording, and then when stopped recording it will loop to certain cuts, so it doesnt record everything? idk im just brainstorming

[polar acorn]

Colliders are on game objects

Components all have access to all of the GetComponent methods

[desert elm]

oh okay

that clears things up, thanks

got confused by the wording, as I thought I needed to get the gameobject that the collider is on, and then get components from that

[short hazel]

Yes you'd want to write the images (or whatever) to a file frequently enough so it does not fill up your memory.

[jaunty lily]

so if i do that, record and write at the same time, then play/loop when needed, this could work and the performance would still be okay?

[short hazel]

Depends on the capture resolution and the computer, so can't say.
Try it, and if you get performance issues, use the Profiler to see where exactly it takes the most time

[jaunty lily]

resolution will not be great, lets say itl be played on a tv from the 90s ;p, still will be visibile and clear enough tho. still, thank you and the rest for helping :)

[desert elm]

nevermind

whats this otherComponent supposed to be?
both of these are wrong

[slender nymph]

look at the warning on your foreach line

[languid spire]

man, C# basics

[desert elm]

this?

[slender nymph]

no, the one that is clearly underlined

[desert elm]

oh i see the problem

[polar acorn]

You need to put that inside your foreach loop

Right now your foreach loop is empty

[desert elm]

yep it works now

fucking typos

[lavish terrace]

is there a place to explore what custom codes can add to the inspector ?

like variables and stuff

seen a vid which added those

made me think what else is there to add

Basically anything.

[dim stream]

Hi, i have a little problem, i am making my first 2d plataform. I created a dead zone for when you fall, the deadzone works but it works only if you touch it for the side, if you fall in it you dont die and idk how to fix it. Here is the code of the DeadZone:

[next jay]

how could i put a delay between lower and raise to prevent both happening at one click

[dim stream]

you have to use the same button?

[next jay]

yeah

[dim stream]

i cant help u im very new here

[next jay]

Ok

[short hazel]

Try making the collider of the death zone thicker.
If you don't move the player in a way that uses the physics system (like using a Rigidbody), it's possible that the player will pass through without being detected.

Modifying the transform.position directly does not use physics for example

[dim stream]

he just stand there

[short hazel]

Then there's a collision, it's just not tagged properly

So it doesn't pass the if statement, and Die() is not executed

[dim stream]

that´s the problem because is tagged correctly

and if you touch it form the side works

an the box is very thick

[short hazel]

Make sure by logging what you hit

[short hazel]

Debug.Log($"Hit object {collision.gameObject.name} tagged {collision.gameObject.tag}")

Then check the console when the player hits the object, and make sure it's correct

[dim stream]

okey

[dim stream]

Idk where to put it 😅

[short hazel]

Whenever you collide, so in your OnCollisionEnter2D

[lost abyss]

hey, i'm trying to create a replica of flappy bird, but for some reason the bird object auto rotates while playing. Anyone knows what I can do to fix that? It's the Z rotation that does that

[dim stream]

ok it collides so now i am very confused

[short hazel]

It always collided, because your player was standing in the air

It's the if statement that didn't pass, making it seem like it wasn't doing anything

Just make sure that in the console it says that it collided with an object that has the correct tag

[dim stream]

its correct

[tender breach]

I fixed my problem for now

[short hazel]

It logs twice, is the script on another object by accident?
From what I see it's meant to be attached to the player only

[dim stream]

im going to check

[next jay]

anyone know how to prevent this?

[dim stream]

yeah it was in another object by accident but we are in the same point

[short hazel]

Put another log, but this time inside the Die() method. So you can see if it gets executed

[open vine]

Hey, so I have a script where I reference the Weapon : scriptableobject class. I thought this meant that any class inheriting from Weapon should be able to be put into the inspector for a Weapon variable is this wrong?

[bleak prism]

If i have a gameobject saved into a variable what would be the best way to access the child of that gameobject

asked the GPT and it said this

[short hazel]

You indeed access parent and children from the .transform

[bleak prism]

So there is no other way to do it?

Just to make sure

[short hazel]

There are plenty of ways, and they depend on your use case

If you just want a specific child, why not drag the child directly into the slot, for example

Like on a variable exposed in the Inspector

[bleak prism]

I could just maybe do that

I keep forgeting about the drag & drop

[dim stream]

what can be the Log

[short hazel]

Debug.Log???

Put any message in it, you just want to see if it's getting executed

[dim stream]

a srry i understand another thing

wtf

[short hazel]

Are you getting any errors in the console? Make sure you didn't disable them accidentally (3 buttons top right of the Console tab)

[dim stream]

i dont have any error its like the character cant make the transition from fall to death

i tried to make a transition directly fall to death

but it doesnt work either

i am going to re edit the animator i think

[rancid musk]

how should i learn c# there are so many different people telling me different ways to start and its really overwhelming

[dim stream]

yt tutorials 😀 👍

idk

im new here too

i made a beginner unity course

but now im using yt tutorials

[short hazel]

Yep now that you have the confirmation that the code is executing, it's an Animator issue

[dim stream]

thank you so much and sorry for the troubles

[grand hare]

I'm not very good but I learned c# using brackey's tutorial on YT. You can follow it but be sure to also write the code, not just watch it

[rancid musk]

okay

[desert elm]

Right so- I assume this won't work, will it
( second image is in the script of the unit component

[slender nymph]

are you sure you are getting the right kind of Unit component inside that foreach loop? hover over it to see the fully qualified name

[shrewd swift]

~~Camera isn't recognized as a Class in my VS
its not colored like a class and isnt giving me any methods

i tried regenerating VS files but nothing changed~~

[desert elm]

just says this

[slender nymph]

then there is likely some context you are not showing

[shrewd swift]

well i restarted VS and everything got fixed, weird

[desert elm]

this is the only relevant code I can think of- any tips on what the important context might be?

[slender nymph]

well for one, it would be great if you stopped sharing screenshots of code

[eternal falcon]

No

Be mindful, if someone requests your code as text, don't send a screenshot!

[golden otter]

in this coding convention:
Public var: exampleVariable
Private var: _exampleVariable

When serializing a private variable using [SerializeField], should it remain with the underscore in front of it or I should remove it?

[slender nymph]

the convention is about the accessibility, not whether it is serialized or not

[golden otter]

alright

[slender nymph]

you should also share what the actual error says as well as the full code for both of the classes

[hidden sun]

any idea?

[desert elm]

https://gdl.space/pivicugemu.cs

[hidden sun]

i set the project id/envoirment/ my id/pass etccc

[slender nymph]

there it is. you've defined your enemyUnit variable as a Component variable and not a Unit type

[desert elm]

oh okay, thanks

[polar acorn]

We could also have seen that if you shared the error

how to add a permanent contextmenu to all my behaviours?

```hacky ![UnityChanwow](https://cdn.discordapp.com/emojis/885169594879320064.webp?size=128 "UnityChanwow")

[wild cargo]

Something like

{
    var component = (ComponentName)command.context;
    // rest of your implementation
}

[zealous oxide]

https://hastebin.com/share/qoyuwenilu.csharp hey peeps, im trying to make a conga line of gameobjects to follow a player object, using a public static array for the transforms but the array never seems to work, it never adds in the playerscript.transform as the first item. is a public static array even the right approach for this

theres very little info for me to work off online for this, so i wonder if i need to articulate it differently

[wild cargo]

Does the followers[0] = playerScript.transform; line in Start() lead to an exception?

Because it seems you haven't even initialized the array yet when you call that

[zealous oxide]

yup!

[slender nymph]

you never initialize the array

[wild cargo]

Also maybe an array isn't the best choice for something like this that can get dynamically changed.. I'd use a List<>

[slender nymph]

honestly a static list isn't necessary either. when one of the objects that needs to follow another is spawned, just pass it a reference to whichever object it needs to follow. and have whatever is spawning them keep a list of what has been spawned

[zealous oxide]

yeah i could do that but if one of the objects gets destroyed in the middle of the chain, i guess it would have to pass the subsequent object into its place? which is getting ahead of myself ability wise

[slender nymph]

have whatever is spawning them also manage destroying them. then when it goes to destroy one, it also tells whichever is following it to follow whatever the destroyed one was following

[zealous oxide]

ok sweet, will do that

[empty yoke]

Dontdestroyonload game objects wouldn't trigger their start function on a scene change, is that correct?

[slender nymph]

correct, Start only happens a single time in an object's lifetime

[empty yoke]

okay so I'd need some like scene manager to trigger any kind of things on a change cool, thank you thank you!

[slender nymph]

there are events you can subscribe to like the sceneLoaded event
https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager-sceneLoaded.html

😮 oh man that's amazing

thank you for the docs!

so I got the door to kind of work how I expected using a hinge. However, once it reaches its limit you can keep pushing it and it gets all like, jittery and weird

I want it to basically become rock solid, as solid as level geometry, if you are trying to push it past its limit

[unborn gale]

[polar acorn]

If you have to ask, probably too hard

[quasi summit]

How come

[polar acorn]

If you don't know enough unity to gauge the scope of a game then any complete game is probably too much

[quasi summit]

damn

how mcuh would it cost tho

[slender nymph]

two things, first make sure that OnCollisionEnter2D is being called
second, do not use Input.GetKeyDown inside of OnCollisionEnter. GetKeyDown is only true for the first frame that you press the key which may not even be a physics update frame. OnCollisionEnter2D is also only called on physics updates and also only the first frame the collision happens. So you have to have inhuman timing to match those up. consider checking input using GetKey inside of OnCollisionStay or just flip a bool in OnCollisionEnter/Exit and check input in Update when that bool is true

[unborn gale]

i would do it for ten bucks if I didnt have a project of my own

[quasi summit]

Really

can u lmk whenever u dont have a project

[polar acorn]

The Three Commandments of OnCollisionEnter2D:

1. Thou Shalt have a 2D Collider on each object
2. Thou Shalt not tick isTrigger on either of them
3. Thou Shalt have a 2D Rigidbody on at least one of them

[quasi summit]

😭

[unborn gale]

so I what would I add instead?

[real falcon]

I would try to find the most similar game you can to your own game and research its production costs

[verbal dome]

People who use the cry emoji often dont want to put any work in themselves, just saying

[slender nymph]

did you not read what i said? i gave you two options for what to do instead . . .

[unborn gale]

how are the player going to get inside the collider if I have istrigger on?

[real falcon]

I think what is happening with my door is that I have a kinematic body pushing on the hinge joint, and I'm thinking for whatever reason the hinge joint doesn't take priority and wont tell the character controller to stop?

[polar acorn]

If either of them are triggers that would be the problem

[unborn gale]

only the hanger is

istriger

[polar acorn]

If either of them are triggers that would be the problem

[unborn gale]

ok

yes it is the problem

what can I do

I wantto detect them when they overlap

[polar acorn]

Either make it not a trigger or use the trigger function instead of the collision one

[queen adder]

how to edit heirarchy search bar via code

[real falcon]

is it a technical limitation that you can't make joints have solid limits against a kinematic body

[verbal dome]

Yeah pretty much. Joints are never 100% reliable, even FixedJoints can go over the limits

And a kinematic body basically has infinite mass when it comes to collisions

[tender stag]

why is it in red but it still works?

[real falcon]

so what is the solution? is it just impossible for a kinematic body to interact with a non kinematic body?

I basically have a player with a character controller and a kinematic rigidbody

I want this to be able to push a door open, but not jitter when it hits the limit

and just block the player

[verbal dome]

Honestly not sure what the best option here is

My rb's are usually not kinematic

[real falcon]

I tried making it not kinematic but unity says I cant

[verbal dome]

Huh? Does it have a mesh collider or something?

[real falcon]

no just a capsule

but the level geometry is a mesh

[verbal dome]

But what does unity say exactly, why cant you make it non kinematic

[slender nymph]

you probably need to regenerate project files

[real falcon]

Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported since Unity 5. If you want to use a non-convex mesh either make the Rigidbody kinematic or remove the Rigidbody component.

[tender stag]

how do i do that

[verbal dome]

The door could check its own rotation and detect when it goes out of limits. When it does, manually rotate it back to the max allowed angle, then detect any overlapping RB's with an OverlapBox and move them away from the door

[verbal dome]

So it does have a mesh collider like I asked
Check child objects if it's not on the parent

[slender nymph]

Preferences > External Tools in unity

[tender stag]

i updated the visual studio code editor

and it works

in package manager

wait no it doesnt

[tender stag]

its just one asset tho

everything else works

[slender nymph]

yes and you recently added this asset so vs code does not recognize it. so regenerate the project files for vs code

[real falcon]

oh for some reason my weapon gui planes had a collider

[tender stag]

still doesnt work

[real falcon]

lol when I make the RB Non kinematic it makes the player fly around like crazy

[slender nymph]

then close vs code and unity, delete the Library folder from within your project, then open them both up again

[verbal dome]

A kinematic rb will need different movement code, of course

[real falcon]

I don't want to make the players movement based on physics because of case in point, how finnicky and glitchy physics sims in games always are

maybe I should just make the door not really use the physics engine

[verbal dome]

@real falcon you could try this idea and see if it makes any sense

[verbal dome]

That is easier yes

Way easier

[real falcon]

thats gonna take a long time to figure out for me how to code that, and I am almost certain it's going to look jittery when you teleport the RB back

[real falcon]

how do I tell when the player touches it tho, and from what angle? and how does it stop when it touches the player, if the players controller stops it before it even penetrates?

[verbal dome]

Not if you do it right, but yeah it takes some time/knowledge tp imolement

[tender stag]

still red

[real falcon]

I remember now that the reason I went to a non kinematic door was because the door would push the player, which would cause depenetration that was jittery

[verbal dome]

OnCollision checks should work

[real falcon]

even if it doesnt end up moving the player?

[verbal dome]

I dont remember all the limitations of kinematic

[real falcon]

should this new door even have a rigidbody?

[tender stag]

disable the collider on the door when its opening/closing

[real falcon]

well, I don't want it to go through the player either

[verbal dome]

Thats how a lot of games do it yes

[real falcon]

the door I'm looking at as an example is from Portal 1, I remember there being a door that you can open and it swings open, but if you try to close it on yourself it just stops as soon as it touches you

and it doens't cause any jittering or anything like that

OnCollisionEnter only works if one of the ojects has a non kinematic rigidbody

which means my door will have to be non kinematic, which means it can bug out

[tender stag]

any idea how to fix it?

[verbal dome]

Kinematic contact pairs are a thing too. Never used it myself tho

[real falcon]

I want something that blocks the player without depenetration or jittering, but is also blocked by the player in the same way

[slender nymph]

if that didn't work then consider switching to a real ide that won't just randomly break

[tender stag]

this is what im trying to access

[tender stag]

i tried using visual studio

not code

same thing

[real falcon]

it acts as pure terrain towards the player, and can only move if it's not touching the player whatsoever

[lavish magnet]

It definitely did help, im figuring it out, and the animator overrider controller would go on tbe player? And i wouldvhave one for eavh gun? Eg dif reload animations.? But thats confusing, dude im sorry but do you think you could hop on call and i could screenshare and shownyoi what i got so we could figure something out, you seem way more knowledgeable abiut this than i am, snd i’ve been stuck on it for like a year, I’m willing to pay even, lmk!

[tender stag]

works now

[real falcon]

the OnCollisionEnter event doesnt seem to be triggering even if the door is non kinematic

its just not running

even when Im physically pushing the door, doesnt show that method runs

this is the players rigidbody

and the doors

[slender nymph]

https://unity.huh.how/physics-messages

[real falcon]

ah I had collider instead of collision thanks

now the question of how to make a door with a rigidbody that the player cannot move at all

without settnig it to kinematic

nvm just set it to kinematic and enabled kinematic collision detection. It actually works pretty well now, I got it moving but stopping if it touches the player and it does not appear to move the player at all, nor does the player seem to be able to move it at all

I get intense lag if I push into it at certain angles but I think that's my own code. I'm worried about coding it rotating in response to collisions but maybe it will be easier than I expect

[tender breach]

How do I change variables across scenes in unity?

[rich adder]

https://unity.huh.how/references/cross-scene-references

[unborn gale]

[north kiln]

Either turn off gizmos generally, or disable the specific one
https://unity.huh.how/interface/gizmos/disabling-icons

[unborn gale]

Can’t find it

[north kiln]

why have you sent a screenshot of a component? That's not where you disable gizmos

[unborn gale]

Where then?

[north kiln]

I'd also note that this is not a code question and you should have asked in #💻┃unity-talk

[tender breach]

[north kiln]

Serialize a reference to the other script and then just access it via the variable of whatever instance you want to change https://unity.huh.how/references/serialized-references

[upbeat river]

can somebody hop into a call with me and help me figure out something?

[vast ivy]

Can’t hop in a call but what’s the rundown on your problem

[upbeat river]

im trying to make a gun

[vast ivy]

Blender

[upbeat river]

and im trying to also make it emit spark particles when it shoots

i have a model and simple shooting (raycasting not projectiles) and reloading

[vast ivy]

Ok so you need an onclick function, have you worked with inputs yet?

[upbeat river]

not really

just started with unity and coding

[vast ivy]

Ok I think if u press edit, Inputs, and then find mouse down inputs

[upbeat river]

hmm ill try

where is the edit?

[vast ivy]

For the code u will need the name of the type of input you’re getting, for example moving your player vertically takes an input of W, S, or Up arrow, Down arrow. This input is called “Vertical”

Should be toward the top left of the editor by file

(I’m also pretty new but this is something I know) xD

[upbeat river]

i dont see inputs but thanks for the help anyways

[vast ivy]

Ok it’s actually in ur project settings tab but here’s the type of code you’ll want:

void Update() 
{ 
    if (Input.GetKeyDown(KeyCode.Space)) 
    { 
        // Spacebar was pressed 
    } 
        if (Input.GetMouseButtonDown(0)) 
    { 
        // Left mouse was pressed 
    } 
}

The update function is in every script by default, it runs every frame. “GetMouseButtonDown(0)” being a left click on mouse

In the if statement is where you would put functionality of your gun

For the reload u would use the “GetKeyDown(KeyCode.R)”

[fierce shuttle]

It would go on the object with your Animator component, so say you had a "pistol reload" and a "rifle reload", you could name the state for both to just "reload", and maybe you start with a pistol, so your default "reload" state in your animator controller could be your "pistol reload", when you swap to your rifle, you can then set the entire animator controller to your "rifle override animator controller", which will replace your "reload" from "pistol reload" to "rifle reload" - so in a way, youd need an animation for every gun that is different (for example if you have 4 different types of rifles, some may reload differently than others, while all the different pistols in your game probably reload the same way and can reuse the same animation) - I wont really be able to do a call or anything until after celebrations here, though if you have other questions, I can try to help, otherwise if your willing to wait about a week, I guess we could discuss it in DM

[tawdry mirage]

how to instantiate empty gameObject from code without any reference?

i only need it's Transform while it is on the scene

[summer stump]

Instantiate()

Or even new GameObject()
Actually, no blank instantiate. I thought there was

[tawdry mirage]

it will not cause memory leaks, right?

only instantiating components outside of gameObject cause leaks?

[summer stump]

What?

[tawdry mirage]

new Transform()

i read it somewhere

[summer stump]

Do you know what a memory leak is?

[tawdry mirage]

in case of unity not really

[summer stump]

It means the same thing in Unity that it does outside

Do new GameObject()
It will not create a memory leak unless you do something VERY weird.

You also can't instantiate components outside a GameObject

[tawdry mirage]

thanks!

[real falcon]

so i have a door that opens if you touch it, the problem is it also opens if you touch it from the wrong side. I'm wondering if there's an easy way to detect if a given movement would end up intersecting an object

specifically, this method is what I use to rotate it. is there a way I can like, "preview" it and see if it would collide with anything before I actually move it?

[tawdry mirage]

if it's raycast based you could use one sided mesh collider.
You can also use three colliders setup, two flat trigger-only colliders for each side and one box collider that works with physics but doesn't trigger

[tender breach]

How do I make it so that a collider only detects a single object.

[summer stump]

Make a layer and set the collision matrix to only detect that specific layer

Or just let it detect more things and validate the collision before doing anything with TryGetComponent or CompareTag
Or a combination

[real falcon]

hmm multiple colliders, good idea. how do I tell which one it touched tho?

I guess probably it tells you in a parameter

[tawdry mirage]

three gameObjects that are child of parent Door

each has to have their own script

[real falcon]

ah

[tawdry mirage]

except one with door box collider

[real falcon]

thats a lot smarter than how I was thinking, thinking i'd have to calculate the direction of the door's motion as a vector and compare it to the direction of the thing you hit etc.

[tawdry mirage]

my solution can cause bugs if you move the touching body at high speeds

it can touch both sides if speed is too high

hmmm, at high speeds you can go right through the door without colliding with it

[steel girder]

hey, does anyone know how to get the length of an animation for a runtimeAnimatorController/animatorOV's animation?

[wintry quarry]

What are you going to do with that number? There's probably a better way

[steel girder]

i knew someone was going to ask this

i'm using it for a coroutine

[wintry quarry]

A coroutine that does what? Have you considered animation events or StateMachineBehaviour for your use case?

[steel girder]

i've considered using the exit animation events however to my knowledge im unable to call instance specific functions for example

it'd make it a lot easier if i could use exit animation events though

~ also to answer your question it fires off an event to a non mono behavior class listener which changes frequently when the coroutine is done playing the aforementioned animations

[queen adder]

can someone help me make prodecural generation for my 2D sandbox?

[steel girder]

hope the information provided is satisfactory, obviously its a bit convoluted and a not a usual system however, if you're able to provide a better alternative im all ears

[wintry quarry]

Wdym by "instance specific functions"? That's the only thing animation events can do if I understand what you mean.

[steel girder]

it's essentially just telling the non mono behavior class instance that it's done the animation

if im able to subscribe and unsubscribe listeners to the endanimationevents via the class though that'd be more than sufficent

[wintry quarry]

Not sure what you mean by endanimationevents

I'm talking about https://docs.unity3d.com/Manual/script-AnimationWindowEvent.html

You would need a MonoBehaviour as the listener here. The MB can call a function on your non MB

[steel girder]

preferably this would be done outside the editor

i was refering to OnStateExit when i said "endanimationevents"

[wintry quarry]

That's for StateMachineBehaviour

Which is the other option I mentioned

[steel girder]

yes, ive just realized that now lmao, unfortunately i still had some issues with that somewhat

[wintry quarry]

What issues

[steel girder]

and my terminology wasn't correct

[steel girder]

as i said i need to do something to specific class instances

[wintry quarry]

StateMachineBehaviour lets you do that

OnStateExit gives you a reference to the specific Animator instance

From there you can do whatever you want. E.g. GetComponent to grab other scripts on that object etc

[steel girder]

issue being im getting the compile time error CS0201

[wintry quarry]

Sounds like you made some kind of basic C# syntax error

But I don't memorize error codes

[steel girder]

thanks for the help in any case friend

ill look into what i did further

if thats the case

[wintry quarry]

If you need help with the compile error feel free to share the code and the actual error message

[steel girder]

solved my issue thank you friend, basic syntax error was all and i was able to fully solve my initial issue

i try to think of myself as well versed in Unity and ofc C# however, i guess we all make basic mistakes!

[dark hatch]

how do i make a simple item system, including consumables and items with abilities on activate?

[static cedar]

Make each type of item an object.
They themselves should be SO.
Then the item slot themselves into structs that holds that item object.

The item slot struct can contain things like count or something but most importantly the item representation scriptable object.

[queen adder]

can we serialize a monobehaviour field and make them assignable in inspector, and be used in code for tasks like Destroy(monobfield)

like assigning a specific mb field, and not the object

[queen adder]

inventory system is a wide feature, there's a tens of ways to implement them. Better check on google first and gather inspirations

[static cedar]

You have three types.

List. Slotted. And multi slot occupying system something.

One is just a list of items. You can sort them or filter.
Second is just a 2d collection of slots.

Third is something like Diablo where items can occupy two slots at once in specific shape.

[dark hatch]

ok

#854851968446365696

don't ask to ask

[steel girder]

depending on what you want to achieve straight up instances of a item class or instances of a class that inherits from a parent item class could offer more flexibility

although for beginners SOs would be better

[dapper solstice]

so if i wanted to damage a player wiht a gun i know i need to send it thru the server first then the client, would i need to make a server script aswell as a script that sits on the player?

[charred spoke]

Entirely depends on the networking framework you are using

[dapper solstice]

mirror with steam works

or fizzysteam wokrs

[charred spoke]

Sadly Im not familiar with mirror or steamworks but there is #archived-networking Im sure someone there knows a thing or two

Hi, I chose the type of Scripting Backend: "LI2CPP" and I have a problem. I tried to look up a solution to this problem on the Internet, but either there were answers to the old versions of Unity and/or I did not understand how to solve it.

playerRb.velocity = new Vector3.zero;
playerRb.velocity = new Vector3(0,0,0);

can anyone explain to me why I can do the second option but the first one doesn't work? afaik they are the same thing (being used in update method in an if statement if that helps)

the console error doesn't seem to like that I don't have an argument with the .zero, but I'm unsure where I would but the () in the first example.

[keen dew]

Vector3.zero is not a constructor, you don't use new with it

[ruby ember]

so i want to add fade effect fade in and out but using 1 button and not like fade in and fade out button like in the tutorials
but i don't want to use animator or animation
and i want it like this video
the game in the video is not mine

[dapper solstice]

so im trying to make a lobbies list i have all the code but the scroll view isnt showing up neither is the lobbies?

and they are active

[wild cargo]

You aren't showing what is going on in the "Content" folder of the scroll menu at runtime so this is kind of hard to answer

As for the scrollbar disabling, it is actually functionality implemented by Unity where if the scroll bar would serve no purpose (eg. content folder is not big enough so scrolling does nothing anyways) it will disable set the alpha of it to 0 until it is big enough again

[dapper solstice]

oh ok

[ruby ember]

@wild cargo do you know how to do this?

[wild cargo]

#854851968446365696 , don't ping users to help that haven't participated in the conversation yet

[wild cargo]

Also why does that map especially look eerily similar to Granny's map? Asset ripped game?

I've reread #📖┃code-of-conduct and I'm unsure if I'm allowed to help you or not, sorry

[woven crater]

hey guys. i want to generate fuction that return random number using a gaussian curve with the magnitue from -1 and 1
the curve take 3 value (a,b,c) where a is the peak value of the curve , b is the lowest value on both end of the curve. c for the ammount of different where c = 0 mean its a straight line with the height of a, the more c increase the curve on both side get steeper

the problem is im bad at math ;w;

i want to do this for better number generation , generate from -1 to 1 and take the value on the curve

[gaunt ice]

a must be 1/2
integral from -1 to 1 a dx=2a=1=>a=0.5

that means ont of the parameter in your function is fixed

[woven crater]

do i need the intergral to be one?

[gaunt ice]

integral of random variable over its domain must be one

[short hazel]

You can use an AnimationCurve, set it in the Inspector, and .Evaluate() it when needed

[woven crater]

ah thank gah

[livid tundra]

I think there is already a function (somewhere) that will return a normally-weighted random variable

[woven crater]

imma try the AnimationCurve thing

[pure garden]

Hello, I've been trying to fix this error for days but I just don't understand why it doesn't do it the way I want it even though I actually think everything is correct

Maybe one of you has an idea and could help me...

It would be really great

Kind regards
Ginsmex

This is the video I used for this
https://www.youtube.com/watch?v=ScxN04YeDj8&list=PLZ1b66Z1KFKit4cSry_LWBisrSbVkEF4t

[short hazel]

The error points to line 13, so either you did not drag-drop an object into the Coin Count Display inspector field, or you did, but it didn't have a Text on it

[gaunt ice]

https://stackoverflow.com/questions/2325472/generate-random-numbers-following-a-normal-distribution-in-c-c
googled how to generate random number based on normal distribution....

[pure garden]

I have it as text and I also specified it at levelcontrol using the C# script but unfortunately I can't get it to work

sry, I'm still a beginner

[short hazel]

Okay it's not a Text, it's a TextMeshPro Text you have attached to that object.
The type is different, you need to use TMP_Text in your code

The tutorial might be a bit dated and was made before TextMeshPro was the mainstream solution

[pure garden]

Okay, thanks, maybe you know tutorials where I can learn in the new generation

[short hazel]

It's pretty much the only thing that changed sensibly, but you can filter your searches so they only include results from the last two years or so

[pure garden]

OK, thanks for the great help

[golden otter]

is calling a UnityEvent in the Update a bad practice?

[wild cargo]

UnityEvents are around 10x slower than regular events, so yes it can be if you're not careful enough

Use regular c# events whenever possible. Basic syntax is
public Action event MyEvent

[golden otter]

Oh didn't know that

Thanks!

[static cedar]

You can opt out of using the event keyword btw.

What the event keyword does is prevent other classes from being able to call it.
And you also can't set it. Just add or remove methods to it.

Removing the event keywords allows anything to access, set, get, and call it. As long as it's accessible (public and stuff).

[wild cargo]

But then when the event keyword gets removed, you can only assign one thing to it (the action)

Delegates should be used in that instance

Could be wrong though, been a while since used delegates in my architecture

[static cedar]

I think you can still assign multiple methods in a delegate. I'm not sure tho. :p

[wild cargo]

        public delegate void MyDelegate();
        public static MyDelegate MyDelegateInstance;

        public void Test()
        {
            MyDelegateInstance += () => Debug.Log("test1");
            MyDelegateInstance += () => Debug.Log("test2");
            MyDelegateInstance.Invoke();
        }

Yeah this works, and also delegates can be invoked from outside the class they're declared in

[static cedar]

If it's not an event, you can use the readonly keyword.
Or make a getter setter and make the setter private.

[wild cargo]

        public static Action MyAction;

        public void Test()
        {
            MyAction += () => Debug.Log("test1");
            MyAction += () => Debug.Log("test2");
            MyAction.Invoke();
        }

But for some reason, this also leads to the same behaviour.. what?

No need for delegates or events

[static cedar]

Lol.

Action are delegates.

Any delegates can be events.

[wild cargo]

So then when should you use delegates? Never?

[static cedar]

You normally make your own delegates for explitness or something. Or use the ref, in, or out keywords.

[wild cargo]

If you have to write more boilerplate to them then there's no point

[static cedar]

MyDelegateForSpecificThing says more than Action<Here's your input, here's your other input>.

[wild cargo]

        public delegate void MyItemDelegate(int myInt, string myString, ScriptableItemData itemSO);
        public static MyItemDelegate MyDelegateInstance;

        // vs

        public static Action<int, string, ScriptableItemData> MyAction;

Like this maybe?

Then the delegates can be reused easier.. but that's like the only benefit

And also the param names

[static cedar]

This isn't a benefit actually.

They only need to match signature. :P

[short hazel]

It is a benefit if you have a lot of them, or the same types

[static cedar]

Like I said, you can also use it if you want to use ref, out, or in keywords.

[wild cargo]

Oh yeah because those cannot be used in Action<T1, T2 ...>

[static cedar]

But I personally used custom delegates instead of Action. I keep refactoring and I want those warnings.

[wild cargo]

So events are basically useful when you want to create a delegate instance that can only be subscribed to by other classes, not called by

[short hazel]

width, height, length is clearer than arg1, arg2, arg3 so yes custom delegate types are better for these use cases

[wild cargo]

Also depends on the name of the delegate instance you have.
For example, Action<int, int, int> OnGridCreated might already be descriptive enough

[static cedar]

Again, it's not a benefit.
You don't see that in the tooltips, only in the declaration. :P

I'm pretty sure you only see. MyDelegate.

I guess unless you do a lambda?

[short hazel]

You see it in the handler method, as when you make VS auto-create the method, it takes the delegate type's param names for the method name

It's useful for when the handler is not in the same type as the one declaring the event

And of course as a tool tip when you invoke the event

[static cedar]

Ah.

[silent geyser]

hello!

im getting this error and my charachter is floating

UnassignedReferenceException: The variable orientation of PlayerMovementTutorial has not been assigned.
You probably need to assign the orientation variable of the PlayerMovementTutorial script in the inspector.

[wild cargo]

You can what UnassignedReferenceException means and if you can't find any results come here again

[rich adder]

its telling you how to fix it

assign orientation

[short hazel]

That error is one of the clearest you'll be getting in Unity

[silent geyser]

ok thanks

[silent geyser]

im newwbie xD

[rich adder]

do you know how to assign something ? its the field in the inspector.
or in code we use =

[wild cargo]

https://www.youtube.com/watch?v=HVucS70Z6Q4

This can also help, it's 2 minutes long
(could be 30 seconds but whatever)

[silent geyser]

and assing it to what

[short hazel]

To whatever the tutorial you're following tells you

You might be doing this later in the tutorial, so it's possible to get the error if you test your game too early

[silent geyser]

i downloaded the script

and gave it to the 3d charachter

[lavish terrace]

simple saving and loading system ?

[silent geyser]

now the carema is floating

[short hazel]

Then I suggest you !learn instead of copy-pasting blindly

[eternal falcon]

:teacher: Unity Learn ↗

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

[silent geyser]

i have a project for university

[lavish terrace]

huh

[silent geyser]

not for my career

xD

[short hazel]

That's not a very good way of thinking

If you're not willing to put in any effort, why should we?

Do some of the beginner courses on Unity Learn, then come back

[silent geyser]

that's not a very good way of thinking

jki

jk

[wild cargo]

How simple do you want it to be? How much are you willing to learn?
If you want to make a very easy-to-set-up system, learn about PlayerPrefs. It has very easy to understand syntax.
If you want to make a more scalable solution with more types supported, learn about JSONs and serialization. This takes more time but is very much recommended

[silent geyser]

ok i fixed the error

but the carema is floating

[lavish terrace]

as of what i heared playerprefs are limited to variables, like does it support dicitionaries ?

[wild cargo]

Nope, neither does Unity's JSONUtility so if you go with JSON create your own SerializableDictionary or use something like Newtonsoft.Json

But JSONUtility is so dogshit I don't recommend using it for a project where you anticipate a lot of saving/loading

[lavish terrace]

that doesnt feel like english

[wild cargo]

Wait one month and all of that will (hopefully) make sense

[lavish terrace]

i just need a way to keep my player data when closing/launching the game

[wild cargo]

What does your player data consist of? An inventory, player name, EXP level, stats?

[lavish terrace]

yea kinda

the inventory is more of a dicitonary with an int itemid , and a bool to know if its owned or not

[wild cargo]

For that kind of data you could use PlayerPrefs but I highly discourage it, because saving collections with it is troublesome

[lavish terrace]

so thats what basically stressing me out

[gilded pumice]

isnt JSON for programs hosted on servers? At least that's all I've ever seen people talk about/use it for. As in, you wouldn't really use it if your game didn't interact with a server somewhere

[rich adder]

JSON is just a formatted text file

[wild cargo]

JSON is used very often in client-server communication (like it's the only method), but that's also what I thought until I learned they are also used very often in local files too

[gilded pumice]

yeah this makes sense. like I said I've only ever seen it being used to interface with servers, at any rate I'm up to my ears learning C# rn so I stay away from additional concepts for now because it will probably only confuse me further

[wild cargo]

I still recommend you learn about JSONs, should take no more than 4 hours to get some kind of system working

That 4 hours is just an approximation, that's how long it took me to learn the gist of it

[lavish roost]

It Just stores data you can use it for anything

[lavish terrace]

sure its gonna be one of my options which iam exploring right now

gonna learn starting with playerprefs

ty for help

[pliant mist]

I want an enemy to go to the nearest point on a sphere around the player then try to stay on that circle and while on the circle shoot the enemy, the last part is easy but I'm not sure how to find the nearest point on a sphere

how should I begin this?

[rich adder]

#🖱️┃input-system

[analog depot]

sorry

yup

[pliant mist]

I think if I get a line from the player to the enemy then subtract the radius I can get a good target point

[wild cargo]

You can just use "Random.InsideUnitSphere * radius" and update that every frame the player moves for a random position

[vast tangle]

i have an assignment and im contemplating where to put the difficulty value of the game
Is it best practice to put difficulty value in game manager? or in a static class of sorts?

The plan is to use that value when I start the game in the game manager.

and the value can be changed from a ui list button

[pliant mist]

well the point should not be random

[wild cargo]

Actually, the random position should not be updated every frame, instead it should get updated when the enemy reaches the target point so it chooses another point in the sphere.

[wild cargo]

Oh nearest point, sorry I misread

[rich adder]

Game Manager with difficulties from SO

[pliant mist]

that's okay, do you know how to find a point on a line x distance from the enemy

[wild cargo]

I think just move towards the player and when it is a specific distance away from it, stop moving nd start shooting

[pliant mist]

it was that easy

the whole time lol

[wild cargo]

If you just move the enemy towards the player it will create an invisible "range" around it when you think about it

[vast tangle]

what is SO?

[wild cargo]

Scriptable Object

[rich adder]

ScriptableObject

[vast tangle]

Thanks!

[rich adder]

each difficulty SO for me has different values

[wild cargo]

Also for these terms

[static cedar]

Two letters can be pretty hard to .

[vast tangle]

would this still apply if im loading the difficulty from a json file?

[wild cargo]

Well, I found results for "unity so"

[rich adder]

json works too

if you have a json with the data you don't really need SO

[wild cargo]

Although they were very sparse so I dunno

[vast tangle]

okay thank you 😄 Have a nice day guys 🙂

[dapper solstice]

can ayone help me out, im trying to make a server browser for steam but every time i go inot the lobbies it doesnt show in the scroll view it spawn ages away

[rich adder]

#archived-networking prob

[dapper solstice]

no its got nothing to do wiht networking

[rich adder]

steam/ lobbies is not networking ?

[dapper solstice]

no no

hold on

[rich adder]

what is this video supposed to show ?

[dapper solstice]

the prefab isnt spawning on the content

it spawn far away from it

[rich adder]

so you outta show both the inspectors for each object involved and the scripts. otherwise its all speculative.

[dapper solstice]

so that where the content is

then thats the "lobby" spawning at 1500 pos z

when the prefab is set to pos z 0

[rich adder]

this seems more of #📲┃ui-ux problem

[dapper solstice]

cheers

[pliant mist]

is there a way to calculate the total degrees required to rotate towards something

I'm using the rotate towards method but that step thing is a pain, it's not exact so the enemy will always be a little off

[lavish terrace]

i have been using the keyword " new " all the time i just dont have any idea what does it do

or mean

[frosty hound]

It means you're creating a new instance of the object type

For example, Vector3 is just a class object. You can think of it as a blueprint/template.

When you want a Vector3, you use the new Vector3(...)

[lavish terrace]

ahhhhh ! so that what it does

makes alot of sense now

[pliant mist]

float singleStep = rotateSpeed * Time.deltaTime;
Vector3 newDirection = Vector3.RotateTowards(transform.forward, targetDirection, singleStep, 0.0f);

transform.rotation = Quaternion.LookRotation(newDirection);```

how do I get single step to be the exact rotation required?

at the moment in under or overshoots

[wild cargo]

Get the angle of the direction in radians using "Mathf.Atan2(targetDirection.y, targetDirection.x)" and set that as the singleStep's value

[pliant mist]

thanks alot

[wild cargo]

Actually, I might be wrong here

Test it and see if it works

If it doesn't, use Vector3.Angle() instead. It gets the exact difference between the 2 positions

[keen dew]

Do you mean newDirection overshoots? It wouldn't make sense for the singleStep to over/undershoot

[wild cargo]

Yeah I was thinking the same because the last 2 params in RotateTowards are "maxXDelta"

So it should just be the upper bound

[keen dew]

RotateTowards is guaranteed to not overshoot so if it doesn't work I assume the problem is with the sprite or model not having its forward vector pointing to the right place

no just saving all code in vs

you're still gonna have to kill the process, hopefully nothing will be corrupted

[cosmic dagger]

That's what I meant. You are in your IDE, then you click (focus) back to unity . . .

[languid spire]

are you in debug mode in VS ?

[lavish roost]

it recompiles after saving you dont need to focus back to unity for it but yeah

[lavish roost]

i exited it

after trying to attach but it doesnt solve anything

[languid spire]

I wonder if there is an artifact still locked by VS, try closing VS, it may free up the Unity process

[cosmic dagger]

Oh, unity automatically recompiles when you save from VS? Try closing VS and reopening it. I didn't know that . . .

[languid spire]

it does, but only when the VS instance is attached to a Unity instance

[lavish roost]

i killed the vs instance unity is still blocked, interesting bug

[languid spire]

indeed, seems like some kind of race condition, I fear kill Unity is the only solution

[lavish roost]

i can just kill the unity instance and get the backup scene right

you had unsaved changes?

[fierce shuttle]

That window is called "IntelliSense" or "CodeLense" though im not sure ive heard of a way to resize the prediction list it shows

[queen adder]

Why? Just scroll...

[lunar tapir]

ah ok, thanks

[lunar tapir]

looks big enough in the screenshot but is hard on the eyes

becomes smaller with this theme for some reason, I'll just change back the theme

[queen adder]

Ok

[rich adder]

dont think that works on the suggestion box

[fluid badger]

I'm new to unity, what exactly does FixedUpdate() func versus Update()?

[frosty hound]

Fixed runs every physics step, Update runs every frame.

[fluid badger]

So I assume I can change the physics update rate?

[frosty hound]

You can, technically. It's not something you normally would need to/want to do.

[queen adder]

Fixed is fixed on 60fps to have accurate physics? doesn't it?

[gaunt ice]

50fps by default

[dry hare]

what do you mean "what about update?"

[rich adder]

show the update method u have currently

btw its prob because my pivot is at the feet and yours at the center, all you gotta do is remove the Y from world pos

[dry hare]

    void Update()
    {
    Plane ground = new(Vector3.up, Vector3.zero); 
    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);





    float horizontal = Input.GetAxisRaw("Horizontal");
    float vertical = Input.GetAxisRaw("Vertical");   
    Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;
    if(controller.isGrounded && _velocity < 0f)
    {
        _velocity = -1.0f;
    }
    _velocity += _gravity * GravityMultiplier * Time.deltaTime;
    if(_velocity < -53f){
        _velocity = -53f;
    }
    

    if(Input.GetKey(KeyCode.LeftControl)){
        Cursor.visible = false;
        Cursor.lockState = CursorLockMode.Confined;
        if(ground.Raycast(ray, out float distance)){
            Vector3 worldpoint = ray.GetPoint(distance);
            var dir = (worldpoint - transform.position).normalized;
            transform.forward = dir;
        }
        

    }```

that's the part that should matter

everything else is just movement stuff

[rich adder]

Vector3 worldpoint = ray.GetPoint(distance);

you're still using local variable

you never writing the variable you made

remove Vector3. should be worldpoint = ray.GetPoint(distance);

from that

but anyway it will still slightly rotate cause ur pivot is in the middle of player and not like feet like mine

[dry hare]

yea alright did that

yea it does the thing now

so from here how would i make it just twist on the y and nothing else?

[rich adder]

worldpoint.y = player.position.y;
 var dir = (worldPoint - player.transform.position).normalized;
            player.transform.forward = dir;```

[dry hare]

does the same thing but... backwards??

[zenith cypress]

Why are you setting the y direction to a world point

[dry hare]

wdym

[rich adder]

ya that should be

worldPoint = ray.GetPoint(distance);
            worldPoint.y = player.transform.position.y;
            var dir = (worldPoint - player.transform.position).normalized;
            player.transform.forward = dir;```

myb

i think

[zenith cypress]

Yes

[dry hare]

YES it works now

thanks

[zenith cypress]

Or if you don't want y, as it seems, just set y to 0 in the direction

[rich adder]

sorry I didnt take my caffeine yet xD

ay yeah I think meant to 0 out that and mixed it with the second

[amber spruce]

hey so i want to have it so while a bool is true then it heals you every 2 seconds

how would i achieve that

[rich adder]

Update or Coroutine

[amber spruce]

how do i make sure the coroutine doesnt fire again beofre the previous one finishes

[rich adder]

store it in a coroutine variable or make bool

[rich adder]

    Coroutine healingRoutine;
void Healup()
    {
        if (healingRoutine != null) return;
        healingRoutine = StartCoroutine(Healing());
    }
    private IEnumerator Healing()
    {
        while (healing)
        {
            //Heal
            yield return new WaitForSeconds(2);
        }
        healingRoutine = null;
    }```

[amber spruce]

and i assume the healing is the bool to say you are healing right

[rich adder]

its only to keep it running

[amber spruce]

and healingRoutine is a coroutine variable?

[rich adder]

yes

@amber spruce you prob dont even need coroutine var you can just check if(healing) return; out the StartCoroutine func

void Healup()
    {
        if (healing) return;
        StartCoroutine(Healing());
    }
    private IEnumerator Healing()
    {
        healing = true;
        while (healing) //set healing to false to exit
        {
            //Heal
            yield return new WaitForSeconds(2);
        }
    }```

[amber spruce]

nvm

i know what i did wrong lol

[rich adder]

this is hella inefficient
PlayerHealth playerHealth = GetComponent<PlayerHealth>(); btw

cache it once

doing that in a while loop is just as bad as doing in update

[amber spruce]

yeah ik but im only really gonna use it once for healing thats it

[rich adder]

but you call it every 2 seconds

[amber spruce]

fixed it

[waxen oracle]

If i used,

obj = GameObject.Find(“Checkpoint”)
dis = Vector3.Distance(transform.position, obj.transform.position)

When there are multiple objects called checkpoint, what would happen

[languid spire]

it would return the first one it came across

[rich adder]

ugly way to find objects don't do it this way

better alternative, have the checkpoints already stored in an array

[waxen oracle]

I could do that

Do for loops exist in c sharp

or an equivalent

[scarlet tiger]

yes lol, loops exist

oh the for loops are like the gml ones

public class PipeSpawnScript : MonoBehaviour
{
    public GameObject pipe;

    public float spawnRate = 2;
    private float timer = 0;
    private float lastPipePosition = 0;
    public float heightOffset;
    public float diffOffset;
    public float acceptedOffset;


    // Start is called before the first frame update
    void Start()
    {
        spawnPipe();
    }

    // Update is called once per frame
    void Update()
    {
        if (timer < spawnRate)
        {
            timer += Time.deltaTime;
        } else
        {
            spawnPipe();
            timer = 0;
        }
    }

    void spawnPipe()
    {
        float lowestPoint = transform.position.y - heightOffset;
        float highestPoint = transform.position.y + heightOffset;

        float newPipePosition = Random.Range(lowestPoint, highestPoint);

        Debug.Log(newPipePosition - lastPipePosition);

        if (Mathf.Abs(newPipePosition - lastPipePosition) > acceptedOffset)
        {
            newPipePosition = lastPipePosition + Mathf.Sign(newPipePosition - lastPipePosition) * diffOffset;
        }

        lastPipePosition = newPipePosition;
        Instantiate(pipe, new Vector3(transform.position.x, newPipePosition, 0), transform.rotation);
    }
}

I'd like to change the moveSpeed of the pipes each time I pass trhough the middle of them the same way I do it for the score but as the pipes are instantiated multiple times due to the spawn function I don't find a good way to do it.

The detail of the code is not really important I just want to know how to change the moveSpeed variable each time I trigger the bird in an other script for all pipes (past and future so they all change the same at the same time)

For the score I do it with a tag but here it doesnt seems to work, I also tried with a list but I don't think its a good way to handle this and it didnt work anyways

Sounds like a job for the flyweight pattern https://refactoring.guru/design-patterns/flyweight I would have a singleton that holds the relevant pipe data like speed and have the pipes read their speed from that one central place. That way if you increase the speed variable of the singleton all pipes will read the new value

any idea whats the theme used here?

[gaunt ice]

no code question
you can ctrl K, then ctrl T choose the theme

[lavish terrace]

public class Flashlight : MonoBehaviour
{
    public GameObject flashlight;
    public bool isOn;
   public Enemy enemy;
    // Start is called before the first frame update
    void Start()
    { 
        isOn = false;
    }

    // Update is called once per frame
    void Update()
    {
          if (Input.GetKeyDown(KeyCode.F))
        {
            if (isOn == false)
            {
                isOn = true;
               flashlight.SetActive(true);
               enemy.sightDistance = 20f;
            }
            else
            {
                isOn = false;
                flashlight.SetActive(false);
                enemy.sightDistance = 0f;
            }
        }
    }
}

im getting a nullreference error both lines with enemy.sightDistance in them

how would I fix it?

[river roost]

enemy is null

[gaunt ice]

where you assign enemy

[brittle plume]

how do i assign enemy

[river roost]

Probably in the inspector

[river roost]

You have to assign it on the Flashlight script

[brittle plume]

should there be a place to assign it?

[river roost]

There should be, that's odd

If you ctrl click "Enemy" in the flashlight script it shows you the Enemy MonoBehaviour right?

[brittle plume]

yes

brings me to the enemy script

[river roost]

You don't have a custom editor?

[brittle plume]

I use visual studio

[river roost]

I meant a custom inspector

[brittle plume]

oh

whats that

[river roost]

you don't have one, but yeah I don't know what could be causing this

Did you change the file name of the Flashlight script?

[brittle plume]

no

[river roost]

try restarting unity maybe?

[brittle plume]

alright

i'll let you know

[acoustic current]

how do i add something (like webGL support) to an editor version?

[acoustic current]

huh??

[brittle plume]

its there!

[river roost]

nice!

thats really odd though

[brittle plume]

yeah

i spent atleast an hour trying to figure that out 😭

and it was just a restart

[river roost]

No idea

[acoustic current]

updated unity hub, still no option

[languid spire]

screenshot your complete hub window

[keen dew]

You're trying to add it to a project. Open the installs page.

and the editor has to have been installed through the Hub, if not then you can't add modules to it

[acoustic current]

my bad

[quaint axle]

Thx helped a lot

[acoustic current]

but it didnt show the option

im gonna install a new version and add it to that

and then remove this old and bugged version

[knotty gust]

how would i program a game object to add itself to an array in the editor instead of at runtime

[amber spruce]

how do i reload the current scene?

so like go back to the start of it

[knotty gust]

SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex); works for me

[amber spruce]

so i can copy and paste that and it should work i dont have to change anything

[knotty gust]

pretty sure but there might be better ways

[amber spruce]

it should work for now thanks

[vast tangle]

If anyone could give me pointers on how to approach this possibly let me know 🙂
I have this object (hollow circle)
and depending on the amount of cuts I ask for it creates separate objects

1 cut gives 2 objects
2 cuts gives 3 equal objects etc.
The more I think about it the more its like a pie chart with equal values
but I do want to seperate them with spacing so it looks like a simon says button board.
anyone have any pointers? 🙂 thanks!

Edit: found this tutorial
https://www.youtube.com/watch?v=9fgZ286pPcY&t
but if anyone has anything to share im keeping my post 🙂

[unreal phoenix]

Anyone know why my models Y rot in the inspector is behaving as a -Z rot?

[cosmic dagger]

You can look at the docs for the method they provided. It'll have an example . . .

[potent echo]

Hey folks, how can I use Random **not **to select a number between two choices, but rather one of the choices themselves? (Similar to random.choice in python)

[verbal dome]

Did you import it from blender?

[languid spire]

make an array of your choices then use
int i = Random.Range(0,array.Length);
val = array[i];

[unreal phoenix]

Yeah, I made the rig for it

[potent echo]

Thanks
