[languid spire]

so you want to apply an opposite force equal to the collision force to player2

[stark ruin]

yes,cause by default unity also if there is not a script behind calculates the collision between the 2 objects

[languid spire]

2D or 3D

[stark ruin]

3d

[languid spire]

so collision has an impulse property, apply the inverse of that

[stark ruin]

the problem is another

when player1 collides with player2,it is like player2 moves also if there is not a script behind that apply a force

[languid spire]

of course, physics is physics, scripts are irrelevant to that

[stark ruin]

ok,is there a way to deactivate the deafult physics and move player2 just with a script that apply the force during the collision?

[languid spire]

you want to alter the standard behaviour of physics you need a script

[hybrid gust]

Make it kinematic

[languid spire]

then no collisions

[hybrid gust]

After the collision you could no?

[stark ruin]

can you explain better? (i know what kinematic is)

[languid spire]

physics has already happend at that point

[hybrid gust]

Collision > make it kinematic > handle the logic however you want > change it back?

[languid spire]

when you make it kinematic you can no longer use force

[stark ruin]

the problem is that when an object is kinematic if i try to add a foce via script it doesn't work

[hybrid gust]

oooooh i see

[stark ruin]

how can i do without collisions?

[hybrid gust]

But you don't want the physics engine to actually do things to the object right?

[stark ruin]

yes

[languid spire]

you cannot, that was a reply to the kinematic suggestion

[hybrid gust]

Why not just set the velocity and anything you want to ignore to 0 then do your logic?

[stark ruin]

i don't really understand you idea

[hybrid gust]

Well from what I understand, you basically have object A colliding with object B, but you don't want object A to do what it would normally do. Kinda like stopping a rubber ball from bouncing when it hits the ground. Naturally it would bounce, but you dont want it to right? So why not just set the velocity to 0 (or basically "reset" the consequence of the collision), then do your logic to do whatever you want to do to Object A?

Or skip the "reset" thing and just do whatever you need to do with with object A on collision

[vapid mesa]

hi, i'm working for a game and i build it but when he can't open it i think is because he don't have open it

what can i do??

because for famous game we don't have to install unity

[stark ruin]

I understand your idea but it would not work in my case

anyway maybe i found a solution

[frosty hound]

This isn't a coding question. If you make a build, make sure you send everything it puts into the folder. No you don't have to install Unity to run a build.

[spiral narwhal]

var newCard = Instantiate(_handCardPrefab, transform);

If transform has the HorizontalLayoutGroup component, does the game object know its "real" position? Because the inspector says it's 691 -156, but if I print the position, it always yields (652.93, 0.00)

[vapid mesa]

k thks

[shell sorrel]

what are you printing

thing its displaying anchored position in there

[spiral narwhal]

transform.position

[shell sorrel]

yeah since this is UI, you might want to get the rect transform

can use GetComponent for that or cast transform

_rectTransform = (RectTransform) transform;

[spiral narwhal]

Doesn't transform get a RectTransform for UI game objects?

[shell sorrel]

its the same object, but because you are viewing at the type Transform

you can not see all of its properties and fields

such as the anchored position value

[dreamy fulcrum]

    private Rigidbody2D[] childRigidbodies;

            // Toggle the Rigidbody2D components of all children
            foreach (var childRigidbody in childRigidbodies)
            {
                if (childRigidbody != null)
                {
                    if (animatorEnabled)
                    {
                        // Set to static if Animator is enabled
                        childRigidbody.bodyType = RigidbodyType2D.Static;
                    }
                    else
                    {
                        // Set to dynamic if Animator is disabled
                        childRigidbody.bodyType = RigidbodyType2D.Dynamic;
                    }
                }
            }
        }
    }
}```

im trying to write a script that toggles all the Rigidbody2D body types of the children of the parent object between static and dynamic but it's also toggling the parent objects Rigidbody2D, any ideas on how to avoid that?

[polar acorn]

You're toggling every rigidbody in childRigidbodies. If that array contains the parent then it will change the parent

[dreamy fulcrum]

any way i can exclude the parent object from that?

[polar acorn]

Don't put it in the array

[spiral narwhal]

Okay, so it seems I found the issue:
The first image is the instantiated object that has its position at 158, -531. The second, which is almost the same position as the other object, however, is at 633, -156. it seems they use a different position system. How do I convert one into the other?

The hierarchy is like this: "Drawn Card Prefab (Clone)" is instantiated and a direct child of the Canvas. It's anchor is in the middle of the screen. "PlayerCardContainer(Clone)" is the child of a horizontal layout group

[dreamy fulcrum]

how?

[polar acorn]

Instead of putting it in the array, don't

[dreamy fulcrum]

how do i chose what to include in the array?

[polar acorn]

How are you adding things to the array

[dreamy fulcrum]

im not really sure how it works actually im just following a tutorial its not very clear

[polar acorn]

Then you're going to have to find out

[dreamy fulcrum]

thats why im here

[summer stump]

When you add something to the array, don't
If it is an array returned from a method, loop over it and remove the thing you don't want

[summer stump]

We can't help without knowing though
You have to figure out how it works on your own, or at least walk us through it as you understand it.

[queen adder]

You could mark the parent with a tag and compare the tag of each gameobject when looping the array

You could also just make a child object that contains the Rigidbodies you do want in the array and put that script on the Child Holder Gameobject that way when it loops it will only get those children and not the parent

[west sonnet]

I've got this script to make the enemy detect the player when they can see the player, but the enemies are able to see the player through walls (Ground Layer). Does anyone know what I'm doing wrong?

[queen adder]

instead of doing LayerMask.GetMask

[SerializeField] LayerMask layermask and pass the layermask field into the function instead

Also if detection is touching ANYTHING detect the player?

Ur if statement should check for the player specifically

Did i say something wrong?

[west sonnet]

What is the LayerMask? I'm struggling to understand what it does in this situation

[queen adder]

A layermask tells wether or not the raycast should collide with a collider

[summer stump]

A layermask is like a list of layers you want to apply

[queen adder]

So in this case the Raycast will collide with whatever gameobject is on the Player Layer and The Ground Layer

[summer stump]

If it is in the layermask, it will return a hit. If not, it will be ignored

[west sonnet]

So, if I had an object that wasn't in the layermask, could the enemy see me through that object?

[queen adder]

Yes

[dreamy fulcrum]

this worked thanks

[queen adder]

Ofc

The raycast will ignore whatever Layers WERENT included in the layermask parameter

So the raycast will phase thru the collider

[summer stump]

You could use RaycastAll and it will return EVERY collider it passes though. Check if the things blocking should block vision

[queen adder]

Ur if statement is ur problem

Ur saying if the Raycast hits anything including the ground

That the enemy can see the player

[west sonnet]

I'm getting a NullReferenceException error on line 27. Why?

[queen adder]

Ur raycast isnt hitting anything

[polar acorn]

Either detection is null or it has no collider

[queen adder]

So the Collider on it is null

Check if the collider is null before comparing the tag

[west sonnet]

So, when detection collides with an object that isn't of Tag Player, it returns null and therefore that error?

[queen adder]

No

When u shoot a raycast it tries to get a reference to the collider that it hit

If the raycast isnt hitting anything it doesnt get a reference to a collider

Hence the NRE

[west sonnet]

Okay

So is it safe to ignore this error?

[shell sorrel]

yeah if its a cast the hit is a struct so you always got a value

no

null check it to see if you got a hit or not

[queen adder]

Never ignore a NRE

[shell sorrel]

if (detection.collider == null) return;
if you want to do nothing on a miss

[queen adder]

Guard clauses. Nice

[spiral narwhal]

            var drawnCardPrefab = Instantiate(_drawnCardPrefab, _playerDeckTransform);
            drawnCardPrefab.GetComponent<RectTransform>().anchoredPosition = Vector2.zero;

Why does the right object spawn at that offset?

_playerDeckTransform is the left object. DrawnCardPrefab is the right object

[shell sorrel]

beats nesting inwards for 90% of a function

[queen adder]

Yeah bro i didnt even know that was a popular thing and had a name until like a week ago

[west sonnet]

This is what I've added. Now, when the player goes into the enemy line of sight and then leaves, the error shows again

[verbal dome]

Give me file-scoped namespaces 😩 I hate indentation

[west sonnet]

But only when the player leaves

[queen adder]

D&M

Inverse that

[west sonnet]

🫡

[spiral narwhal]

"is" instead of == is even better because of operator overloading :p

[queen adder]

Check if its null first

[wind raptor]

Can static methods be called from an uninstantiated singleton?

[queen adder]

Yes

Static means its not tied to a instance

[shell sorrel]

no

[spiral narwhal]

Anyone? :(

[ionic zephyr]

someone knows how IEnumerator works?

[shell sorrel]

you want to make sure you hit the overloaded == unity has and not do a direct null check

[summer stump]

Yes. It is an interface with methods like Next
For enumerating (moving over) a collection

[queen adder]

Yeah unity has stated alot that there null check isnt C#s null check and that the objects under the hood arent really null

[ionic zephyr]

any resource I could check

[summer stump]

Microsoft docs

[spiral narwhal]

Yes not for Unity objects

[shell sorrel]

in the given usecase it was a collider though

[spiral narwhal]

ah gotcha ✅

[shell sorrel]

yeah for non unityengine.object stuff i use is, ?. and ?? all the time

[spiral narwhal]

drawnCardPrefab.transform.SetParent(newCard.transform);

Why does setting the parent change the position?

[shell sorrel]

https://docs.unity3d.com/ScriptReference/Transform.SetParent.html

look at the docs for it

[west sonnet]

How can I compare Layer rather than Compare Tag, in my If() statement?

[gaunt flume]

whats the easiest way to detect how long a key has been pressed for and print the time to the console?

[shell sorrel]

it has a 2nd arg

[shell sorrel]

Input.GetKeyDown and Input.GetKeyUp

or simply Input.GetKey and add up delta time while its true

[spiral narwhal]

Oh so set that to true?

[shell sorrel]

yeah otherwise it does not keep world pos, but keeps its local pos

[spiral narwhal]

            var drawnCardPrefab = Instantiate(_drawnCardPrefab, _playerDeckTransform);
            drawnCardPrefab.GetComponent<RectTransform>().anchoredPosition = Vector2.zero;
            drawnCardPrefab.transform.SetParent(newCard.transform, true);

Mm, still seems to create that strange offset

This is the result without the set parent line

[noble summit]

what game are you making

[queen adder]

NGL im interested to

[spiral narwhal]

Something like Gwent :)

The standalone one

[queen adder]

Ahh The witcher Card Game is dope to

Is the card supposed to go to the top of the deck?

[spiral narwhal]

Yes it's supposed to spawn there, so that it can move to the player's hand

Like a draw animation

[queen adder]

Im not to familiar with the u wanna animate this so keep that in mind

But when u spawn (Instantiate) a card is it offscreen or does it just appear on top of the deck?

[spiral narwhal]

Wait let me record a gif

[low path]

try setting local position to vector2.zero. i think what's happening is you are setting the anchor to 0 but that doesn't actually change position

setparent also doesn't change the position with what you're doing

[spiral narwhal]

This is my issue

If I uncomment the set parent line, there is an offset

[queen adder]

Are the cards prefabs?

[spiral narwhal]

Yes

[low path]

set parent, set anchor to 0, then set local position to 0

[queen adder]

Should world position stays be set to false?

[spiral narwhal]

Ok let me try

[low path]

you might be able to not set anchor? not sure

[spiral narwhal]

By anchor to zero, you mean anchoredPosition?

[low path]

yeah

[spiral narwhal]

Didn't work sadly

[queen adder]

Im not to familair with UI

But why dont u just spawn on top of the card deck and then set the parent ?

Can't you just grab the RectTransform of the top of the deck and then Instantiate a card there?

[spiral narwhal]

Yeah let me try that

[queen adder]

If I’m not wrong this can cause a problem with different resolution

It might im not sure tbh

[queen adder]

After you done it, try the lowest and the heightest resolution

But even if the runtime of the position changed depending on resolution whatever reference you have to the RectTransform should update as well i would assume

Emphasis on assume

[queen adder]

I think your idea is ok, but you need to get the screen resolution

Because newly created ui during runtime doesn’t count screen resolution (I think)

[spiral narwhal]

            var drawnCardPrefab = Instantiate(_drawnCardPrefab, _canvasTransform);
            drawnCardPrefab.transform.SetParent(newCard.transform);
            drawnCardPrefab.GetComponent<RectTransform>().anchoredPosition = new Vector2(
                _playerDeckTransform.anchoredPosition.x,
                drawnCardPrefab.transform.position.y
            );

Locking y seems to work right now

[queen adder]

Did you tried changing resolutions?

Always try that, because when you try the game once finished your gonna have a bad surprise (talking with some experience by now)

[spiral narwhal]

Yup! Picks the right spot as well

[queen adder]

Good

Wait my idea worked?

[queen adder]

Yes congrats

[spiral narwhal]

idk this one seemed to do the trick :D

[queen adder]

Lowkey was a shot in the dark lmao

Im glad it worked tho

[fading rapids]

anyone know how to make tilted (where i slide of off) objects count as if im grounded i deleted the layer Ground from the objects but doesnt work

[summer stump]

Why did you delete the ground layer from them?

All you need a low friction pysics material on the objects (and set it to use minimum)
I'm also assuming you are using a rigidbody

[fading rapids]

wdym

i thnk u dont understand what im trying to ask

[summer stump]

See #854851968446365696
If explicitly says do not respond with wdym

[fading rapids]

oh mb

[summer stump]

No, I don't

[fading rapids]

sorry

[summer stump]

You want to slide off objects that are tilted, right?

Oh, you want them to COUNT as grounded

So they just need the ground layer on them

[fading rapids]

they do

[summer stump]

And use a physics query wide enough to hit it

[rustic jolt]

Does anyone know if Error lens or something like that exist for Visual Studio? I'm not talking about Visual Studio Code

[summer stump]

Ok, I'm extra confused then.
You said:

i deleted the layer ground from the objects

oh yh i obvously put them back was just trying if that would chaneg anything(which it would obviously not)

but ty

i understand the problem

[summer stump]

Ok nice, sorry I misunderstood at first. Glad you got it

[fading rapids]

im reading my question again and damn that was confusing

[short hazel]

There's Code Lens yes, the little indicators that show how many times a property or method is used, for example.

It should be enabled by default, but they can be disabled from the settings.

Dot notation, which c# uses, does it like this
Thing . Thing inside the thing to the left . Thing inside the last thing

The words to the right are in the words to the left

[wind raptor]

Why doesn't Visual Studio like this?

char[][] HIDCodesToASCII = new char[256][];
HIDCodesToASCII[0x04] = ['a', 'A'];

Squiggly line under the bracket before 'a', says Invalid Expression Term '['

[short hazel]

You cannot create arrays with the [ ] syntax in the C# version Unity is using

[wind raptor]

ah. k

[short hazel]

You need to do something like = { 'a', 'A' } or = new char[] { 'a', 'A' }

[wind raptor]

Yeah it accepts the second one... Hmm. I'm going to be typing this out 100 times or so. Any recommendations on how to accomplish this more succinctly?

[short hazel]

With a for loop? What are you trying to do here?

[wind raptor]

get a jagged or multideminsional array of characters, the first index of which is represented by an HID code, the second of which is indicates whether it's changed due to shift or capsLock

[short hazel]

Right. Depending on the characters you're going to put in the array, and whether the indices are consecutive, you can do it all in one loop. Characters are convertible to int so you can do pretty neat stuff with them

for (char c = 'a'; c < 'z'; c++) { }

[wind raptor]

I'm just being lazy

Right but ultimately I should probably be putting the HID codes into an enumerator anyway

[calm hull]

public virtual is used when you have heritage but its implemented in the father right==

??*

[wintry quarry]

I think you are saying "heritage" when you mean "inheritance"?

[calm hull]

yes sorry

not english

[wintry quarry]

virtual means "a child class is allowed/permitted to override this method"

without virtual, you cannot override the method

inheritance itself happens no matter what when you have a class derived from another class.

[short hazel]

Again it all depends on if these codes are consecutive or not. Sometimes preparing the data in Excel or in an online compiler can remove a lot of the hassle

[calm hull]

so if i have a dealDamage() method it would be
public abstract void dealDamage(int damage);
in the father and
public void dealDamage(int damage)
{
//code
}
in the children? im using like this and it says error if i dont use override

when its not virtual

@wintry quarry

[wintry quarry]

abstract is different from virtual

virtual means you may override
abstract means you must override

[calm hull]

ohhhh i see

[wintry quarry]

and if you have neither abstract nor virtual , then you cannot override

[west sonnet]

In my Enemy script, I have a bool that determines if the enemy is alive. When the enemy is shot by the player, the bool turns to false and that stops the enemy from being able to function.

The problem is, if I kill 1 enemy, then all the other enemies that have the same script also stop working. Because of this, I can't use it as a prefab. How can I prevent this?

[summer stump]

Did you make the bool static?

[short hazel]

Seems like that boolean is wrongly marked as static? Or you're modifying the boolean on the prefab instead of one of its instances in the scene?

[brave robin]

Is the bool static?

[short hazel]

Triple

[summer stump]

Triple kill

[west sonnet]

No

[west sonnet]

No

[summer stump]

Are you changing the value of the prefab instead of the instance?

[wintry quarry]

you'll have to show your code because your explanation doesn't add up.

[west sonnet]

I deleted the prefab, so I just have a singular enemy in my scene with the scripts attached

[wintry quarry]

if there's only a singular enemy, then your explanation makes no sense

because it mentions multiples

[west sonnet]

I meant that I have multiple, I've just copied and pasted them

I have 2

[wintry quarry]

if there's a prefab being used to spawn things, there should be ZERO enemies in the scene at edit time

[wintry quarry]

ok show your code already

this is a code channel after all

we'd want to see the enemy script and whatever script is damaging/killing the enemies

@wintry quarry one more question please. once i made all the childs im thinking to do a controller which put all the GameObjects in a list and then call to their Attack() one by one. How would i do that in unity?

maybe there is a better option

you said it had to do with enemies dying

[summer stump]

The spam-bot will hinder you more than it helps

[wintry quarry]

you said this

[west sonnet]

When I kill an enemy, the bool which determines if the enemy is alive turns to false. i thought this might be the issue?

[wintry quarry]

which bool is that?

I don't see such a bool in your code

I see canKillPlayer

[opaque matrix]

could be true, first time i used it. might do it again but won't rlly as it won't help me improve.

[west sonnet]

Yes, this. It turns to false on a particle collision

but htat's pointless

[calm hull]

once i made all the childs im thinking to do a controller which put all the GameObjects in a list and then call to their Attack() one by one. How would i do that in unity?

and is there a better option?

[wintry quarry]

because in your player code you're doing this:
https://gdl.space/popeyikuma.cs

if (collision.gameObject.layer == 8 && EnemyFollowRef.canKillPlayer == true && EnemyFistDamageRef.punchTypeEnemyCanHit == true)```

you're reading canKillPlayer from SOME specific enemy reference that you drag and dropped

you should be getting the component from the object you collided with

and checking it on that object

instead of some specifically dran & dropped enemy reference

basically there's no reason these fields should exist:

    public EnemyFollow EnemyFollowRef;
    public EnemyFistDamage EnemyFistDamageRef;```

The player should not have these references

[west sonnet]

I should check for the canKillPlayer on the collided object?

[wintry quarry]

yes...

doesn't that make sense to you?

[brave robin]

EnemyFollow collidedEnemyFollow = collision.gameObject.GetComponent<EnemyFollow>(); like that

You probably also want to make sure the collision is with a gameobject with that component first before you do anything else with it, or you'll get an NRE

[west sonnet]

This is what I've done. Is this correct? Because I still have the same issue

[rare basin]

Or just use Try GetComponent

[west sonnet]

How do I do that?

[queen adder]

TryGetComponent is the cleanest approach

[brave robin]

if (thisEnemyFollow == null) { // do stuff differently, or just return }
GetComponent<> gives you null if it doesn't find the component, so if the player collides with something that doesn't have it you'll get a null reference exception if you try to do anything with that null reference. So catching that is important

[timber comet]

collision.GameObject.TryGetComponent<EnemyFollow>(out EnemyFollow enemyScript)

[timber comet]

Something like this, you can then use enemyScript inside your OnTriggerEnter

[queen adder]

wrap that in a if statement

{
  reference.MethodToCall()
}```

[timber comet]

here, this is a good example of it

[queen adder]

That way you can just do whatever u need to with the reference and if u dont have the reference then just do something else

[west sonnet]

Why did you add "out EnemyFollow enemyScript" at the end?

[queen adder]

Multiple return types

[timber comet]

you need to add it anyways

otherwise it wont work

[queen adder]

TryGetComponent<> returns a bool to see if it does have the component but it ALSO has to return the component and it can only do that with the out keyword

[timber comet]

but i added this so you have a reference to that component

so you can use that in your script as a normal variable

[queen adder]

The out paramater is the same as doing: variable = return value from a method

But the syntax is a bit weird for it

Your basically just assigning a value

[timber comet]

yeah it is, i was so confused when i first used that

[queen adder]

I changed the explanation incase that doesnt make sense D&M

[short hazel]

You can see regular arguments as giving values to the method. With out, it's the inverse: the method gives a value back to the code that executed the method.
And since that in C# methods cannot return more than one value (with the return keyword), then it uses out

[brave robin]

out also means the variable that's used in the parameter will be modified, rather than returned in a form that can be discarded or used as you wish.

[inner bane]

anyone knows how can I change the third person camera's position over the character's shoulder? I use Third Person Template scripts for character controller and camera

I can make a script for it or smth?

[west sonnet]

Is this correct? Because now no enemy does damage to me

[rich adder]

jesus

[wintry quarry]

you need it to have both components?

Also there's no need for == true

[rich adder]

thats a cursed ass ifstatement

[west sonnet]

😦

[verbal dome]

Does the enemy have child objects with colliders?

[west sonnet]

Yes, but it's a trigger

[low path]

in general, why don't you just break this stuff down a bit and use debug.log's to figure out how the behavior differs from what you expect

rather than going back and forth and having us guess

[verbal dome]

You are trying to get the component from the object that has the collider

Isn't the component on its parent instead?

[calm hull]

how can i load a list of Characters from the combatManager? like have them all in the list

[verbal dome]

What is combatManager?

[wintry quarry]

wdym by "load"?

[calm hull]

its a empty GameObject i did to manage the combatOrder

and i need to fill the list with all the characters

[verbal dome]

Each character could add itself to the list in Start, for example

combatOrder is/has a script component, right?

[calm hull]

yes!

    // Update is called once per frame

    }
}

i want to put that list with the objects

[verbal dome]

You could add a method to that script, something like RegisterCharacter(Character character)
And each Character, when created, would call CombatManager.Instance.RegisterCharacter(this)
But first you would need to make CombatManager into a Singleton

That's the .Instance part

[calm hull]

so in the start of the objects?

i see

how can i make it a singleton sorry

[verbal dome]

This page explains singletons
https://gamedevbeginner.com/singletons-in-unity-the-right-way/

Give it a read, it will be useful in game dev.

For these kinds of manager classes

[calm hull]

i see

thanks

ill check it now

uff

global class

isnt that ilegal xD

or i can use it fine if its on the manager

[verbal dome]

It's a very common pattern in game dev

[timber comet]

You should use a static, only on object you know you only need one

[verbal dome]

As long as you know that only one instance of the singleton will exist

[timber comet]

So it’s fine using it on a Manager

[calm hull]

i see

i dont break the encapsulation

[timber comet]

But for example it cannot be in a Enemy script, ‘cause you need more than one

[calm hull]

im new in game dev obv

i see

[timber comet]

No need to encapsulations

You can do it, also, on Awake

[calm hull]

what on awake

[verbal dome]

Yeah you don't directly modify the singleton's variables, using a method is good (like my example RegisterCharacter)

[timber comet]

Basically, it’s when the scene is loaded(I think)

It starts before Start, and is useful in case you want to put a reference of the static in another script in Start(), ‘cause it can cause an error if both are in Start()

[timber comet]

Awful explanation but I hope you understood something

[verbal dome]

Yeah it can be done in Awake.
I just like to separate awake/start so that in Awake you do "internal initialization" (no references/dependencies to other objects) and Start for stuff that needs some other objects to be initialized first.

[calm hull]

i see

[verbal dome]

Because you can be sure that every object's Awake has already been called when Start is called

[calm hull]

This is the Singletone:

public class CombatManager : MonoBehaviour
{
    List<Personaje> list;
    public static CombatManager Instance { get; private set; }

    // Start is called before the first frame update
    void Start()
    {
        List<Personaje> list = new List<Personaje>();
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    void RegisterCharacter(Personaje character)
    {
        list.Add(character);
    }
}

This is the object:

public class Aliado : Personaje
{
    // Start is called before the first frame update
    void Start()
    {
        currentHP = maxHP;
        CombatManager.Instance.registerCharacter(this);
    }
}

Its not right, could you help me find how to instance that method?

[rocky canyon]

https://docs.unity3d.com/Manual/ExecutionOrder.html heres the order of how unity functions get called

may be useful

[hexed terrace]

Youre CombatManager.Instance hasn't been set to anything

[rocky canyon]

you got this part

but are missing this part

source: https://gamedevbeginner.com/singletons-in-unity-the-right-way/

[calm hull]

oh that on Awake is needed

i thought was other way of doing the same

[rocky canyon]

check out that site

theres different ways to do it

[verbal dome]

I linked it a moment ago

[rocky canyon]

ahh sorry, i just stepped in

[calm hull]

also i didnt put the registerCharacter public

and i tried to access it

ok now i get it more less

is there a way to check if it works fine? like cout the list

but here xD

as its paralel i cant debug

[verbal dome]

Yes but you can also just serialize the list so it shows in the inspector:cs [SerializeField] List<Personaje> list;

Private fields won't be visible unless you tell unity to serialize them

[wintry quarry]

wdym "paralel"? You can certainly use Debug.Log

[calm hull]

this is a new list?

cause it say i cant have both this one and the one i had

i mean sorry if my questions are stupid

[verbal dome]

Same list

Just add the SerializeField attribute

[calm hull]

ohhhh

[verbal dome]

But yep you can also use Debug.Log to print stuff out

[calm hull]

i see

and this will show it on the inspector?

IT WORKS

LETS GO

after 3 hours

feels good

damn thanks

sorry if stupid question

[verbal dome]

No worries, they were not stupid questions

[calm hull]

i need to read more documentation

but its diffult some times

[sand frost]

Guys why would I use while() instead of an if() in the update void?

[low dawn]

i js spent like 3 hours

trying to find out why intelisense wouldnt work

[frosty hound]

Because you will get a stack overflow and your game will freeze.

[low dawn]

im gonna cry

[sand frost]

So I should use while() instead of i

If

[frosty hound]

No, never use while unless you know what you're doing.

[sand frost]

Oh

Unity learn taught me while()

[rocky canyon]

and btw its an Update Method or Function void is the return type..

like Vector3 or Float

[sand frost]

Ha

Ah

[frosty hound]

What was the context it was used i

[rocky canyon]

it irks me to hear "update void" or "why my void not work" lol

[sand frost]

Like while integer =1 or something then do whatever

Don't remember clearly

I gotta check later

I actually gotta go to class now 💀

I'm eating lunch

I was just thinking so I decided to ask right now

But now I gotta go 💀

[clear seal]

i modified my canon for it to shoot only if reloaded and it weirdly does not work

[rocky canyon]

an if statement is for making decisions based on a condition, executing code once if the condition is true. A while loop is for repeating a block of code as long as a condition is true

but in the context of unity and the Update() loop for example its pretty similar.. if statements are the easier / thing u learn first

while loops take a little more pre-thought and get more useful more advanced u become

[formal arch]

having this issue where because its inherited, it runs the manager script a second time when the weapon selection is enabled, which results in the starting weapon being spawned in twice... whats a way I can solve this?

[wintry quarry]

It's unclear why the reload thing is its own script and which object/script it's referencing

[wintry quarry]

what's inherited from what? Which function is running twice?

[rocky canyon]

why do this in start? if ur onenable does it anyway?

[formal arch]

the start function is running twice

[wintry quarry]

which start function? Unity only calls Start once per object. Inheritance doesn't change that

[formal arch]

did it to see what was running as i didnt know what the issue was

[short hazel]

A class instance that's inherited is only present once. There isn't one instance per class definition

[rocky canyon]

ahh okay

[formal arch]

yeah, thats why im assuming its being spawned in twice

[wintry quarry]

yes, that would have nothing to do with inheritance

[clear seal]

health system is supposed to reference the player
reload canon script is suposed to declare if the canon is loading by going in it(invisible :0 )
select script is the canon script

[rocky canyon]

you can pass context thru the debug

[short hazel]

You have this script twice in your scene, at some point.

[rocky canyon]

to see whats running it

Debug.Log("Start has run, by: " + this);

[formal arch]

what would i put in to reference what is calling it

[rocky canyon]

that way to see why it gets run twice

[wintry quarry]

Unity Engine itself calls Start

[short hazel]

Debug.Log("message", gameObject) - upon selecting the log in the console, it'll highlight in the Hierarchy which object sent it

[rocky canyon]

whats running it the second time.

[formal arch]

this is the issue, im unaware of what is

[rocky canyon]

thats why the extra context..

it should only be run once.. unless theres two versions of it

[wintry quarry]

just search the scene for your script

[rocky canyon]

u cant manually call the Start() function from what im aware

[wintry quarry]

t: WeaponManager

(if that's the script name)

[formal arch]

It's being ran by the weapon selection controller, the script on the right but cant find how or why, like you said the start function cant be run, only by unity when its spawned in

[rocky canyon]

yup, sooooo there has to be (2) of em.. if ur seeing the start function.. debug (2x)

make sure u dont have a phantom version of the script on the gameobject somewhere

[short hazel]

Debug.Log($"Running WeaponManager.Start on {gameObject.name} (ID: {GetInstanceID()})", gameObject);

If you get two logs but the object name or Instance ID is different, then you have two scripts attached.

[radiant frigate]

hi! does someone know why the position of the object the script is atached to doesnt match with the position my mouse should be on?

[wintry quarry]

Does that script derive from the other script?

And you have both scripts in the scene?

If so then yes that makes perfect sense. A class that derives from another class inherits all of its members, including the Start function

[modest dust]

https://docs.unity3d.com/ScriptReference/Input-mousePosition.html
https://docs.unity3d.com/ScriptReference/Transform-position.html

[wintry quarry]

you're mixing up world space coordinates (transform.position) with screen space coordinates (Input.mousePosition)

[rocky canyon]

im 100 percent sure it does debug the value of mousePos.. and debug the value of transform.position

[radiant frigate]

i readed them but cant figure out how i should make the center of the screen be 0, 0 and not the down left corner

[wintry quarry]

There's no reason to "make the screen" do anything

convert your mouse position to a oworld space position is what you need

[radiant frigate]

and how do i do that?

[wintry quarry]

Use one of the options in this article: https://unity.huh.how/screentoworldpoint

[radiant frigate]

srry im very new at programming and just got back at it again

[rocky canyon]

        Vector3 mousePosition = Input.mousePosition;
        transform.position = mousePosition;

        Debug.Log($"{mousePosition} + {transform.position}");

[queen adder]

can someone help me find the part of the script where when you finish dialogue it switches the scene

[radiant frigate]

im doing it in a 2d game

i dont know if that changes something at all tho

[rocky canyon]

doesn't matter, it'll still log the same..

theres a bit more to it than setting it = to mouse position

https://docs.unity3d.com/ScriptReference/Camera.ScreenToWorldPoint.html @radiant frigate check this link out

[short hazel]

There's no such thing in this script right now. But, the very last else is configured to disable the object this script is on when there are no more dialogue lines to display.

[radiant frigate]

omw and ty for the help!

[queen adder]

oof

ima just put a button

that says finished or skip

its going well

[radiant frigate]

okay so what i understand is that screen is measured by the pixels and the world point is the x y z, so what i have to do i wirte ScreenToWorldPoint before it so it transforms to WorldPoint?

[short hazel]

What you could do instead, to make that script more versatile, is to expose a UnityEvent you'll invoke when the dialogue has ended.
If you used a button before, it's like the "On Click" box where you can drag-drop a script and select a function. But in your own script.

// Declare
public UnityEvent DialogueEnded;

// Invoke
DialogueEnded.Invoke();

So on one of them you could wire up a function that displays another dialogue, and on another wire up a function that changes scenes

All of that directly from the Inspector, without ever touching the insides of the script

[queen adder]

i already got button and closed unity out
I got it covered.

[radiant frigate]

i think this should work right?

[slender nymph]

https://unity.huh.how/screentoworldpoint

just make sure you specify a z position for the mousePos otherwise it will be the same as the camera's z position so it will be too close to render

[radiant frigate]

so i should just do z = -1?

[calm hull]

once i have a list with gameObjects ordered by turn, how can i make so that till the first one attack it dont move to the next one

all the gameobjects update at the same time?

like, do they all start same tic

[rocky canyon]

z would be in front of ur camera.

so 10 is a normal go-to

totally up to you tho what u set the z to

[clear seal]

idk what is that but it looks cool

[nocturne parcel]

Do you mean like a turn based combat? I.E, only the object can act in the object's turn?

[calm hull]

exactly that yes

i made a singletone and i have all the objects on a list

[rocky canyon]

my project will also need a system like this

[night mural]

You'll need something which is keeping track of all the objects and some way for it to tell when each object has done its thing so that it can move to the next one. How that works is pretty much up to what game you're making.

[nocturne parcel]

Well, there are many ways to do that. It's a very broad question. I suggest trying find some tutorials.

[rocky canyon]

haven tmade it yet tho

irc brackeys has a turn based tutorial.. like a pokemon battler thing

its basic as it comes.. might be able to get an idea of where u wanna go and how ud go about it

[nocturne parcel]

But essentially, you want a state machine that keeps track if the game is in a turn (so it pauses) or if it can move on (turn finished).

[night mural]

if you have DoTween, you could build a big ol' sequence with each object's actions and run through that

[clear seal]

but does onbuttondown or on mouse down make you click with ray?

[nocturne parcel]

Or that

I think I overcomplicated lol

[rocky canyon]

https://www.youtube.com/watch?v=_1pz_ohupPs

something to look thru to get u started maybe

[naive lion]

    {
        Debug.Log("Trigger Enter");

        LayerMask mask = LayerMask.GetMask("Environment");
        if (other.CompareTag("Player"))
        {
            playerHealth.Damage(damageValue);
            Destroy(gameObject);
        }
        if (other.gameObject.layer == mask)
        {
            Debug.Log("Test");
            Destroy(gameObject);
        }
    }```
Hey guys really weird issue I really cant figure out
My trigger works fine but when it comes to detecting it the trigger moves into a gameobject within a specific layer it does not recognise it
I have done VARIOUS debugging such as debugging the layer it detects on enter, it only seems to recognise the player and enemy, and i have applied the layermask in editor

[rocky canyon]

i actual have my own method.. when u click down it starts the sequence.. then you can hover / and hold which is 1 type of selection.. or u can drag away from the object 2nd type of interaction.. or u can release 3rd kind of interaction

[slender nymph]

the layer property of a gameobject is the layer index, and LayerMask.GetMask returns a bitmask not the layer index. check this page out to learn how LayerMasks work https://unity.huh.how/bitmasks

[clear seal]

ye but i saw someone having a problem with something called onMouseDown and does this make it click with raycast?

[rocky canyon]

https://pastebin.com/3spGauC7 yes i shoot a ray into the world using the mouse position

you can check the code here.. but its a WIP and pretty nasty atm

[clear seal]

i will check it thanks

[rocky canyon]

when u press down it Starts the Sequence.. then it'll know if ur dragging or just hovering over the object you clicked..

depending on which one it does different things when u release

[clear seal]

so this is all differant function?

[rocky canyon]

the click calls 1 function.. and sets drag and hold both to true..

then those bools are in the update.. while they're running they both have an exit conditional (if i drag away from the object hold becomes false..)

if i release the mouse (drag becomes false)

[clear seal]

👁️ 👄 👁️

[rocky canyon]

same with the hold.. if i move off the object hold becomes false.. if i release the mouse hold becomes false..

[clear seal]

i d not understand

i will check it later

[lost anvil]

Can anyone give me an idea on how i can create a door similar if not a copy of the door opened at the start of this video?

The part i want is the way the player can control the doors movement with his mouse, and collider.

https://www.youtube.com/watch?v=sQVUhEojF8A&ab_channel=nullnull

[clear seal]

here you go show it

is it the same tho?

[rocky canyon]

you can see the booleans change on the right..

[clear seal]

i meant for @lost anvil

the door he showed looks like it's the same

[rocky canyon]

ahh 👍 but still.. just wnated to show what it does..

when i click i set all the bools to be true.. and then afterwards the update loop has the if(drag) and if(hold) each one is waiting for me to move away from the object.. or release the mouse

depending on which one i do first.. it'll set the bools to false.. so the loops stop running

and the action eventually happens (like selecting it) or (making it look a direction)

at that point i have to click again for the bools to go back to true and start over again

its a super simple/ if() type of state machine 😄

[spiral narwhal]

_transformContainer.localRotation = Quaternion.Euler(0f, 0f, degrees);
How would I do this smoothly?

[rocky canyon]

that i need to refactor at this point

[clear seal]

perfect :0

i dont understand but still looks interesting

[spiral narwhal]

Like MoveTowards for Vector2

[clear seal]

keraunos has the same door type as you

[rocky canyon]

u probably want some type of physics.. you can use a sphere or something hovering in front of the player to manipulate it..

when u click u could for example add a hinge joint from the hovering sphere to the door

when u move ur mouse the floating sphere or w/e would follow.. and the door would be moved inthe process

[lost anvil]

ah right gotcha, ill have a crack at it thanks

[rocky canyon]

ooor.. u can just use the starting mouse position and just detect when u go to the left or to the right

and u could translate that into a regular torque force on the rigidbody

[lost anvil]

would that be simpler?

because it sounds it

[naive lion]

am i correct in saying that instead of LayerMask.GetMask, I should use LayerMask.NameToLayer

or am i still misunderstanding

[slender nymph]

why are you even comparing the layer in the first place

[naive lion]

i have a prefab that moves when instantiated
attached is a trigger
I am trying to see if a gameobject within [layer] is passed through the trigger, if so destroy

[rocky canyon]

https://www.youtube.com/watch?v=3i-d6leI7Q4&ab_channel=FreedomCoding

[slender nymph]

that does not explain why you are comparing the layer
it is almost always better to just check for a tag or specific component and use layers to filter out unwanted collisions

[rocky canyon]

yea, the attched rigidbody would be more immersive (would be something more suited for VR) and picking up objects..

but u could take the shortcut of knowing exactly what axis ur rotating on.. then ud just need mouse values..

[clear seal]

dont trust the code in desc stuff, it's a trap

[rocky canyon]

rotate this way or that way

[rocky canyon]

i never trust code.. the way to do it is learn the concepts.. and then study the actual code / functions urself..

[clear seal]

yep i did this error, i was too lazy to code so i downloaded scripts

[naive lion]

okay noted
ill avoid this approach

[clear seal]

i did not understand when i wanted to change it

[rocky canyon]

exactly what happens

if u want the identical thing.. sure copy.. but when u wanna change stuff thats when it falls apart if u dont understand the basic concepts ur using

[dapper zenith]

Guys why wouldnt the the Animation tab not open , im going Window > Animation > Animation and nothing opens, i cant ge the Window tab to open at all?

I dont have any Console errors or anything either

[spare mountain]

is it already open somewhere

#💻┃unity-talk

[rocky canyon]

it may be off the screen

my animation window always goes on my 2nd monitor for who knows what reason

[dapper zenith]

yeah it was on my Graphics tablet that i couldnt see because it was turned off lol

[rocky canyon]

reset ur layout

and it'll make everything where it should be default

[spiral narwhal]

How do I check if localRotation is approximately a certain value?

[rocky canyon]

use a variable and expose it in the inspector.

[spiral narwhal]

No in code

like Vector2 Distance < 0.1f

[rocky canyon]

ohhh mb lol 🤣

[slender nymph]

what is the actual use case for this? because there might be a better way to accomplish whatever it is you are trying to do

[naive lion]

just for context
i did fix this tho im not going w this method anymore
i found a reddit thread that stated for ontriggerenter to work properly, a rigidbody is needed which i wasnt aware of

            (
                _transformContainer.rotation,
                targetRotation,
                step
            );
            
            if (_transformContainer.localRotation REACHED) STOP
        }

[slender nymph]

I'd guess that your player has a CharacterController which can also send OnTrigger messages

[rocky canyon]

if (Quaternion.Angle(transform.localRotation, targetRotation) < angleThreshold)
{

}```

[naive lion]

AH thats it!
yeah makes sense now

appreciate the pointers

[spiral narwhal]

I'll try thanks

[rocky canyon]

no problem, ive never used it.. but the docs seems to say thats how it works

[slender nymph]

use your words to describe it. don't just throw a bunch of pseudocode and expect everyone to know what you are actually trying to accomplish because that does not explain it. that just explains your current attempt at doing whatever it is you are trying to accomplish

[rocky canyon]

and angleThreshold would be something small.. the smaller the closer it'd have to be to the target for it to return true

[calm hull]

why i cant use
enemy1Unit.TakeDamage(damage);
if the enemy unit is a child of other class?

[slender nymph]

what happens when you try

[calm hull]

it says Unity dont find the definition for the method

but its written down

[slender nymph]

can you provide actual error messages instead of a vague approximation of it

[calm hull]

its not in english

let me change lenguage

1 sec

'Unit' does not contain a definition for 'TakeDamage' and no accessible extension method 'TakeDamage' accepting a first argument of type 'type' could be found (are you missing a using directive or an assembly reference?).

[slender nymph]

it sounds like you probably have a variable of type Unit which is not an EnemyUnit. you need to cast to EnemyUnit if that is the derived type that declares that TakeDamage method

of course you haven't shared actual code and you keep modifying the error message you've posted so that's really just a guess based on the little context you've provided

[calm hull]

let me send it sorry

This is my battleManager the problem is on line enemy1Unit.TakeDamage(player1unit.Attack1());

public enum BattleState { START, PLAYER1TURN, ENEMY1TURN, WON, LOST }
public class BattleManager : MonoBehaviour
{
    public GameObject playerPrefab;
    public GameObject enemyPrefab;

    public Transform player1Position;
    public Transform enemy1Position;

    Unit player1Unit;
    Unit enemy1Unit;

    public BattleState state;

    void Start()
    {
        state = BattleState.START;
        SetupBattle();
    }

    void SetupBattle()
    {
        GameObject playerGO = Instantiate(playerPrefab, player1Position);
        player1Unit = playerGO.GetComponent<Unit>();


        GameObject enemyGO = Instantiate(enemyPrefab, enemy1Position);
        enemy1Unit = enemyGO.GetComponent<Unit>();

        //setup de las HUDS -> playe1HUD.setHUD(player1Unit) idem con enemy

        state = BattleState.PLAYER1TURN;
        PlayerTurn();
    }

    void PlayerTurn()
    {

    }

    void PlayerAttack1()
    {
        //diferenciar si es un ataque en area
        enemy1Unit.TakeDamage(player1unit.Attack1());
    }

    public void OnAttackButton1()
    {
        if (state != BattleState.PLAYER1TURN)
            return;
        StartCoroutine(PlayerAttack());
    }
}

The class Allie and Enemy are the same:

public class Enemy1 : Character
{
    // Start is called before the first frame update
    void Start()
    {
        currentHP = maxHP;
    }

    // Update is called once per frame
    void Update()
    {

    }

    public override void TakeDamage(int damage)
    {
        currentHP -= damage;
        if (currentHP <= 0)
        {
            Death();
        }
    }

    public override void Death() { }

    public override void Attack1()
    { }
}

Its like Unit dont get the function cause its the children class?

i couldnt do it shorter sorry

its a basic attackTurnSystem

[slender nymph]

yeah so this is the answer #💻┃code-beginner message

[rocky canyon]

show Unit

that's what the error is about.

[slender nymph]

you have to cast to EnemyUnit (or whatever the derived type that declares that TakeDamage method is called) because that method does not exist on the Unit class and you cannot use members from derived classes unless you have a variable of that type or an even further derived type

[calm hull]

i see... thought i could declare units on derivative classes and access the ,ethods

[slender nymph]

you can only access the members that are accessible to that class because it doesn't know about any of its derived classes, it only knows about itself and its parent classes

a simple thing to do would be to type check and cast using the is operator like if(enemy1Unit is EnemyUnity enemy), or just store the enemy as an EnemyUnit

[pastel dome]

https://hastebin.com/share/tifunepuxa.csharp my update method isnt quite working out lol

it keeps getting faster the longer i hold down fire

its supposed to fire every 1 second

[slender nymph]

what is the value of volleyDelay (in the inspector)

because that appears to be the only thing that prevents it from firing again

[rocky canyon]

in fire volly ur not resetting the velocity..

as a result each new projectile inherits the velocity of the previous one

[pastel dome]

0.8 second

[calm hull]

GameObject playerGO = Instantiate(playerPrefab, player1Position);
player1Unit = playerGO.GetComponent<Unit>();
this problem is here right? Sorry bit lost

[slender nymph]

no that is not the issue since that is not the enemy unit

[pastel dome]

ok thanks spawn

if (Time.time >= nextGlobalCooldownTime)
{
nextGlobalCooldownTime = Time.time + globalCooldown;
}

i think thats the problem but its shooting like multiple volleys instead of every second

[calm hull]

you mean when i declare it? or the class of enemy itself

[rocky canyon]

different issue then...

how are u calling the function to fire them?

[rocky canyon]

the issue is on Unit script..

it can't find the TakeDamage() function

[calm hull]

but its there 😢

[rocky canyon]

show the unit script

youve shown Enemy1 and BattleManager but not Unit so far

[calm hull]

the second code here

oh

[rocky canyon]

no thats BattleManager

[slender nymph]

#💻┃code-beginner message
in the BattleManager do this

[rocky canyon]

i wanna see Unit

or boxfriend may already have a solution.. idk

[calm hull]

omg

i got it

finally

thanks for the patience @slender nymph

[haughty stream]

Hello!, I am having a problem with the triggers and the colliders, what is happening is that my player has a script to take damage and it is interacting with all the enemy's colliders, what I want is for it to only take the collision with it parent object of the enemy and a child that is the one that has the collider for the animation.

[wintry quarry]

Put the separate colliders on different layers and use layer based collisions to disentangle the interactions

[haughty stream]

This is the damage detection script

[haughty stream]

ok ok I'll try that tnks

[vernal plume]

how would i make it so this only applies to me going forward

instead of both forward & backwards

[rocky canyon]

if verticalInput is positive..

[vernal plume]

like this?

[wintry quarry]

that's negative

[vernal plume]

oh wait yea

[rigid cobalt]

is this code only for 3d or does it work for 2d

[summer stump]

Which code?

[rigid cobalt]

this

[summer stump]

That has nothing to do with 3d or 2d, so it will work in both

[rigid cobalt]

thanks

[wintry quarry]

it's not going to be useful outside of that person's particular script.

[sour ruin]

hi, how to reduce collider visibility to a single layer? exclude everything but the layer or include only the layer or both in the layer overrides area. How to dynamically change this from code?

up to u how u use them

[rigid cobalt]

is this a good place to learn unity https://www.gamedevrocket.com/

[oak mist]

Ay I have a dumb question, I’m trying to get an empty to move around a pivot when I give a player action. Any idea how I can go about that

Basically what i am using to give the gameObject the angle to rotate
currentAngle += rotationInput * rotationSpeed * Time.deltaTime;
currentAngle = Mathf.Clamp(currentAngle, minAngle, maxAngle);

i just need it to then move around a 'pivot' tp that position

again, dumb question. Im an engineer and i cant figure it out

[summer stump]

No idea. This is the best I know of, and it's free !learn

if ur using an empty object.. that is the pivot..

[rigid cobalt]

alright i will check it out

[summer stump]

Oh yeah, that one costs money? No, it's trash

[rocky canyon]

just offset the object (the child) and rotate the main object

[rigid cobalt]

which one gamerocket?

[summer stump]

Yeah
Learn.unity.com is free

[oak mist]

right, but basically i have a turret targetting it, so i want to move that empty game object so see movement

[rigid cobalt]

nah its free if u go to the dudes channel

[oak mist]

so i would have to create another empty gameObject for that gameObject to move around?

[rocky canyon]

yea, u just rotate it.. theres many ways

do u want it to look at a certain target?

[oak mist]

yes

the target moves in an arc

[rocky canyon]

as long as u have the gun of the turret facing the same direction as the forward axis z then it should work fine

[chilly edge]

I'm making a controller and having an issue where what should be the forward/backward input is making the character go up/down.

The script only lets me assign x and y to a vector2, but unity is taking that y as up/down, not forward/back. Is there some way to fix this either in the script or unity itself?

[didnt mean to send this while a convo was up, mb]

[oak mist]

alright

thank you

just wanted to make sure

[summer stump]

Ok, that's better at least. The whole page looks super predatory though. Classic snake oil tactics. I would be highly suspicious of it

Edit: oh god, it's $700 USD! Insane

[rigid cobalt]

ok

wait why is k banned

[summer stump]

Because it is a single letter

The message explains why

[rigid cobalt]

ohhh

[rose imp]

It keeps saying the non convex mesh collider with non kinetmatic body doesn’t work, any tips on how to fix?

[oak mist]

So firstly, for contect, the game is in space, this will make sense

when rotating, the pivot doesnt really move the position of the turretsTarget, so when you move at certain angles, the turret will change directions

even if it wasnt told to

[rocky canyon]

ya, make it convex

you cant use physics on concave colliders (non- convex) (colliders with valleys and/or holes)

think of a bubble of syranwrap around ur collider.s.

if you need some advanced shape you either have to build it from multiple simpler type colliders.. or buy an asset that does it for you (i think)

[mighty prairie]

Can someone tell me how to remove the .csproj files form the side in VSCode. Really frustrating

In the unityExternalEditor settings I turned all the settings off and they still appear?

[summer stump]

You turned them off an then what? Did you click regenerate project files?

[mighty prairie]

Yeah i did, didn't change anything. Just did it to test it to no avail just yet

[summer stump]

Have you tried just deleting the .cspoj files?

[slender nymph]

yeah just delete them, then regenerate project files when only the types of csproj files you want are selected

do note that you will not get autocomplete and stuff for types in the assemblies that you do not have csproj files for

[mighty prairie]

Oh I see, I'll do that, that is why i was hoping to hide them over delete them hm

[slender nymph]

if there's some way to do that, it would be in the vs code settings. and if you need help with the vs code settings, you'd be better off asking somewhere more specific to vs code rather than a unity server

[mighty prairie]

Thankyou, I'll give that a try, I have seen some ways online but I'll look into it. Thanks all

[supple citrus]

In my solution a preset is a list of objects. I want a list of every preset. This means I need a list of lists. Is that stupid and is there a different structure thats lets me do it more easily

[vernal minnow]

Would a list of arrays not work?

[rocky canyon]

lol! thats the only other thing i was thinking of too 😄

[vernal minnow]

I was trying to crack a joke tbh😅

He most likely needs the list of lists

[rocky canyon]

wooooosh.. haha

what about a Class? with a constructor..

[eternal needle]

You havent described what the actual problem is, so not really sure what answer you are expecting

[rocky canyon]

and list of Classes instead..

[vernal minnow]

He probably is looking for a simpler way to store his data

[cosmic dagger]

I would make a class with a list field and use a list of the class . . .

[supple citrus]

I was just wondering if a list of lists is... bad

[rocky canyon]

public class Preset
{
    public string Name { get; set; }
    public List<object> Objects { get; set; }

    public Preset(string name)
    {
        Name = name;
        Objects = new List<object>();
    }
}

List<Preset> listOfPresets = new List<Preset>();```

hows this? haha, j/k i have no idea whats the best approach..

but i hear people using lists of lists all the time

[sour dome]

I have a script to paint tiles (basic 2 types, green/blue). I'm planning to tag the green (grass) tiles so I can grab them into an array and randomly generate a portal on one of those green tiles. Does anyone see a problem with that approach? Here's the script that creates those tiles of that helps explain my scenario.

Note: at the moment, it's only painting 1 color (green) for now.

[summer stump]

I would call it suboptimal in terms of readability

The suggested list of a class that contains a list would be easier to deal with

But a list of lists is not inherently bad, no

I'm trying to change the animator parameter "isAttacking" to false when the animation has completed so that it doesn't repeat the animation but it doesn't seem to work. Any thoughts?

[rich adder]

Use animation event to set isAttacking back to false

[queen adder]

If you're trying to stop the repeat animation, select animation Clip and in Inspector, turn "Loop Time" off.

[craggy oxide]

what's the difference between Quaternion.Euler(0, 0, 0) and Vector3(0, 0, 0)?

[rich adder]

one is a rotation , one is not

[craggy oxide]

so Quaternion.Euler is essentially just the Vector3 of transform.rotation?

[rich adder]

its euler angles to quaternion

in unity what you see in inspector is euler angles, so only xyz needed

[craggy oxide]

What's the difference between transform.rotation and transform.localRotation?

tuple

[ivory bobcat]

A tuple isn't the same as a List

[supple citrus]

shit

list is {} isnt it

[summer stump]

For initializing it with values, yeah I think

myList = new() { value1, value2 }

I can't remember

[ivory bobcat]

List is a dynamic collection of items. A tuple-value is a coupling of several values.

[rich adder]

hmm yeah they prob tried to init it with (f,f,f)

[supple citrus]

i tried to add a list to a list

But it seems you cant do it directly and you need to add a list variable

like this

Apparently you cant serialize Vector3's so I have to do each component

ugh

[summer stump]

What is the list?

You can definitely serialize Vector3 though

[supple citrus]

When i try it just bugs out

and this guy said it 7 years ago

[summer stump]

You can't directly serialize monobehaviour's without a workaround, yeah. But vector3 is fine.
But you were adding it to a list, not saving a file.
What is the list?

[supple citrus]

A list of everything im saving

[summer stump]

And what are you serializing with?

[supple citrus]

Json

[summer stump]

Ok but WHAT is the list?

Show the declaration

[summer stump]

And json is the format, what are you using to serialize TO json?
Different serializers have different capabilities

[supple citrus]

JsonUtility?

[rich adder]

If you're using JsonUtility you can serialize anything unity can, if you're using something like JSON.net you do not have vector3 without workaround.

[supple citrus]

I clearly do not know how to use JsonUtility

I will continue doing the work around and just store it as a text

🙏

[rich adder]

perhaps share error or show what isn't working exactly ?

[rich adder]

looks like trying to serialize a MB?

[supple citrus]

Yeah but thats after doing multiple

[rich adder]

just save the data on it in a plain c# object

don't use mb

[supple citrus]

what is mb :d

[rich adder]

Monobehaviour

[supple citrus]

I was serializing this list

[rich adder]

preset is serializable?

[supple citrus]

Ye

preset has monobehaviour though

if thats an issue

[summer stump]

It is an issue

[rich adder]

yeah why not just the data on it? then recreate on load

You can serialize the MB but doesn't like list of list iirc

[supple citrus]

What does a successful serialization look like lol

Not this i am guessing

[wintry quarry]

A successful serialization has all the information you want serialized.

[grand sigil]

how do you make a height of an object based on the overall height of its children?

[wintry quarry]

Is that a #📲┃ui-ux question?

[supple citrus]

I should say what Im serializing to make sure its possible.
A list of presets
Each preset has a name, date, List of Suns, List of Planets
each Planet has Vector3 position, Vector3 velocity etc.. a bunch of vector 3 stuff

[wintry quarry]

the thing you're serializing needs to be serializable

[supple citrus]

I was told JsonUtility is good for all Unity variable types

[wintry quarry]

The rules for serialization are here https://docs.unity3d.com/Manual/script-Serialization.html#SerializationRules

idk what "all unity variable types" means

that's very vague, and definitely not true.

[grand sigil]

oh yeah,

my bad

[summer stump]

Which is the monobehaviour? The Suns? And what are Planets

[rich adder]

Unity has a problem if the Item in the List is a MB type
(it will store the instance ID of the MBs not the data)

[craggy oxide]

does rb.AddForce account for gravity?
I noticed that when I update transform.position for physics it creates a curve and works with rb.gravity
but when I put the same variables into rb.AddForce it just sorta flies

[polar acorn]

AddForce adds force. It doesn't "Account" for anything. There is still gravity, also adding force

[wintry quarry]

You should never be updating transform.position if you're using a Rigidbody
AddForce has one effect and one effect only which is to alter the object's velocity.
If you're plugging a position vector into AddForce, that makes no sense at all. Nonsense input = nonsense results.

[cosmic dagger]

You shouldn't manipulate the transform as it does not use the physics engine. It will fight against any physics methods, like AddForce . . .

[craggy oxide]

in that case how do I specify direction

[wintry quarry]

Wdym? AddForce accepts any force vector you wish

a vector is a direction and a magnitude all in one

[craggy oxide]

you said "If you're plugging a position vector into AddForce, that makes no sense at all."

does that not mean "don't use vectors"

[wintry quarry]

are you wanting to add forces or are you wanting to set the velocity directly or are you wanting to set the position directly?

[wintry quarry]

it doesn't mean don't use vectors. It means don't use position vectors

[craggy oxide]

either #1 or #2, definitely not #3

[polar acorn]

It means don't use a position

[craggy oxide]

i'm not doing that

[polar acorn]

It takes a force

[wintry quarry]

from your original description it seemed like you were.

[craggy oxide]

actually this would be easier to send the code

[wintry quarry]

maybe share your code

yes

[craggy oxide]

private Rigidbody rb;
private Vector3 forwardForce;
private Vector3 upwardForce;
public int upwardForceMultiplier;
public int forwardForceMultiplier;

    // Start is called before the first frame update
    void Start()
    {
    rb = GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
    forwardForce = Vector3.forward * Time.deltaTime * forwardForceMultiplier;
    upwardForce = Vector3.up * Time.deltaTime * upwardForceMultiplier;

    rb.AddForce(forwardForce, ForceMode.Impulse);
    rb.AddForce(upwardForce, ForceMode.Impulse);
    }  

[wintry quarry]

AddForce should never be used in Update

it belongs in FixedUpdate only

you also shouldn't be multiplying the force by deltaTime

[craggy oxide]

oh yeah haha

double oh yeah

god damnit

[wintry quarry]

and you shouldn't be using Impulse for continuous forces

[craggy oxide]

okay that part i didn't know

[wintry quarry]

you did 3 things wrong here

[craggy oxide]

what should i use instead

[wintry quarry]

nothing

the default

i mean it really depends what kind of effect you're going for

[craggy oxide]

yeah i actually know about not using time.DeltaTime and using FixedUpdate for rigidbodies i just forgot lmaooo

[wintry quarry]

why are you adding two forces as well?

[craggy oxide]

the 3rd thing i dont have much experience with tho

[wintry quarry]

Why not just one force in the direction you want?

[craggy oxide]

tryna create a curve

[wintry quarry]

a curve is a thing that happens over time

it's not something that would be expressed in an AddForce call

If you want to see a parabolic motion curve you can just do this:

void Start() {
  rb.velocity = new Vector3(5, 5, 0);
}```

gravity and momentum will take care of the rest

if you want some other kind of "curve", well you'd have to explain what

[craggy oxide]

wowie that's nice and easy

i've been tryna figure out curves cause im tryna make like, fireballs and grenades and stuff, arc projectiles

any other key info you think could help with that

[wintry quarry]

if you think about how projectiles like that work in real life, there is usually one big force at the start to throw them

then they just fly on their own

that's what my code example is doing

it's just setting an initial velocity, and letting momentum and gravity take care of the rest

these things don't get forces added constantly as they fly

just once at the start

(unless you count the force of gravity)

[craggy oxide]

hmm okay ill keep that in mind, i like that way of thinking, very practical

quick question

if you set rb.gravity to -1 or lower does that invert it

[wintry quarry]

rb.gravity is a vector

it's the acceleration of objects it affects in m/s^2

by default it's (0, -9.8, 0) in Unity (which is similar to real life Earth gravity on the surface of Earth)

[craggy oxide]

so... how do i invert gravity then :P

imagine the curve you just described, but happening upside down so the object flies infinitely upwards from the inverted gravity

[wintry quarry]

Well Rigidbody doesn't have a gravity property

Unity 3D Physics has only a global gravity property
Unless this is 2D

You can set the global gravity with https://docs.unity3d.com/ScriptReference/Physics-gravity.html

[craggy oxide]

how would i go about creating object-oriented inverted gravity

[wintry quarry]

you would probably set the "global" gravity to 0 (or set useGravity to false on it) and implement your own gravity

it's very simple:

void FixedUpdate() {
  myRb.AddForce(myCustomGravity, ForceMode.Acceleration);
}```

where myCustomGravity is a Vector3

[craggy oxide]

would this create a curve similar to the one that global gravity has

like, say now I dropped the object, would it curve downwards for a bit but then start flying upwards after the apex of the arc

[wintry quarry]

I wouldn't have written it if it didn't.

[wintry quarry]

it wouldn't go downwards at all if you didn't give it a downwards velocity

also, assuming you set your gravity vector to have a positive y value

[craggy oxide]

wouldn't there be conflict between the two forces though

[wintry quarry]

what two forces?

[craggy oxide]

cause it's not like the custom gravity has any special treatment compared to the other force that would hypothetically create the downwards velocity

[wintry quarry]

wdym by "conflict"?

[craggy oxide]

lets say i make the gravity inverted but then give the object downwards velocity too wouldn't they cancel each other out

[wintry quarry]

Forces are in conflict all the time

[charred spoke]

You set apply a gravity to false then use your custom one

[brazen narwhal]

does random.range never select/chose the last option?

[wintry quarry]

when you stand on the ground, the force of gravity is canceled by the force of the ground pushing up on oyu

this isn't a problem

[charred spoke]

Thats how forces work

[craggy oxide]

oh okay
