[thick goblet]

That's the only script I have attached

I'm trying to rework it in some way I'm just not sure

[languid spire]

can you screenshot the inspector of the gameobject

[tender stag]

wait can i call functions here?

like in the set

[gaunt ice]

yes

get setter are function call

[languid spire]

Ah, right, you have a Rigidbody attached. instead of setting transform.position in your script use rigidbody.position @thick goblet

[cosmic dagger]

after the value is set, yes . . .

[thick goblet]

Ohhhh

I would never realize that thank you

[languid spire]

rule of thumb, never mix transform and rigidbody movement

[verbal dome]

rb.MovePosition to keep interpolation
Nvm you probably dont want that here if it is supposed to teleport

[thick goblet]

Yeah it works perfectly now

[sharp bloom]

I'm probably just dumb but why doesn't this work?

[gaunt ice]

https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

you can read the overload methodsof instantiate here

[sharp bloom]

Ah thanks I get it, I'm missing the quaternion rotation

[tender stag]

should the items know which slots there in?

if yes i can do it simply

the durability

[verbal dome]

Whats the slots got to do with durability?

Is it that only items in a slot will decay?

[tender stag]

like when i shoot i can just item.cell.RefreshDurability();

update the cell the item is in

same for food

[verbal dome]

Ok so it is just for UI?

[tender stag]

yeah

i mean idk

i think so

i could use it for other things

[verbal dome]

A clean way would be to use events or something

[tender stag]

thats what im doing

[verbal dome]

Make the UI system listen to an durability change event

[vast yoke]

vector3 is not a transform.

[swift crag]

Correct. There are a few different overloads for the Instantiate method

Same method name, different arguments.

None of them take only a position

You'll want either Quaternion.identity for a "default" rotation, or enemyType.transform.rotation if you actually want to preserve the prefab's rotation

[twilit nest]

Het I'm trying to rotate a head along the Z axis. In the Scene editor it automatically adjusts for the position aswell. How do I do this in code when I just try to edit the Z rotation it goes around the player body.

This is the current code I use for rotating the head.

y = Input.GetAxis("Mouse Y");

Vector3 headCenter = bodyHead.transform.position + bodyHead.transform.up * radius;

bodyHead.transform.rotation = Quaternion.Euler(bodyHead.transform.eulerAngles.x, bodyHead.transform.eulerAngles.y, bodyHead.transform.eulerAngles.z + y * sensitivity);

[wintry quarry]

In your editor you have your tool handle pivot set to "Center"

set it to pivot and you'll get the same behavior as the code when rotating

Also there's a much better way to do the rotation:

Quaternion rotation = Quaternion.Euler(0, 0, y * sensitivity);
bodyHead.transform.rotation *= rotation;```

[wintry quarry]

If you want the code to rotate around a certain point you need to either:

• adjust the mesh in blender to have its pivot in the correct place
• introduce an empty parent object to the head with the expected pivot and rotate that parent object instead of the head itself

[twilit nest]

How do you set the pivot of that empty object? I already have an object in which the sphere and eyes are located but now I see in the editor that that's at the same position as the bottom of the body.

[mental spade]

hi, i have this problem with player animations in unity. heres a video of what happens when the player should stop as i let go of all the keys( https://youtu.be/DNTlrbIxQNE) there's some sort of a delay before changing isMoving to false
also here's the HandleUpdate function
public void HandleUpdate()
`{
if (Input.GetAxis("Horizontal") != 0f || Input.GetAxis("Vertical") != 0f)
{
animator.SetBool("isMoving", true);
animator.SetFloat("moveX", Input.GetAxis("Horizontal"));
animator.SetFloat("moveY", Input.GetAxis("Vertical"));
}
else
{
animator.SetBool("isMoving", false);
}

    if (isMoving) // Sprawdź, czy ruch jest włączony
    {
        movementDirection = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
    }
    else
    {
        // Zatrzymaj animację ruchu, gdy ruch jest wyłączony
        animator.SetBool("isMoving", false);
    }
}`

[teal viper]

Input axes have an interpolation of the value from 1/-1 to 0. It's not immediate. That's the whole point of the input axes.

[wintry quarry]

the empty object's pivot is just its position

like I said before you need to set your tool handle position to Pivot, not Center to see it properly

Press Z to toggle it

[twilit nest]

oh I got it thanks alot

[loud dragon]

my project has got stuck at one point as when i am taking reference from the one script to another it is not sowing any changes in the 2nd script when something is getting changed in the 1st one

[wintry quarry]

you need to share details

such as code and how things are set up in the scene

and what you are doing and expecting to happen, and what is happening instead

[loud dragon]

can i share the package

as evenafter sharing codes it is not getting clear

[sharp bloom]

Wanted to spawn an enemy either in pairs or four in a square. This works but I'm sure it's spaghetti.

Hey guys, i'm trying to add bullet spread to my 2D top down shooter. however, the bullet keeps coming out at very peculiar angles when i shoot the gun. in the code below, which is the part that needs fixing, FirePoint is the point from which the bullet appears, and also is facing in the direction that the bullet needs to be fired in. can someone tell me whats wrong?

        Vector3 BulletDirection = FirePoint.rotation.eulerAngles;

        if (Input.GetKey(KeyCode.Mouse1))
        {
            BulletDirection.z += Random.Range(-bulletSpreadADS, bulletSpreadADS);
        }
        else
        {
            BulletDirection.z += Random.Range(-bulletSpreadHipFire, bulletSpreadHipFire);
        }

        FirePoint.rotation = Quaternion.Euler(BulletDirection);

        GameObject bullet = Instantiate(bulletPrefab, FirePoint.position, FirePoint.rotation);
        Rigidbody2D rb2d = bullet.GetComponent<Rigidbody2D>();
        rb2d.AddForce(FirePoint.up * bulletForce, ForceMode2D.Impulse);

[polar acorn]

So, I think the problem here comes from the fact that each time you fire you are permanently rotating your fire point, meaning the randomness of the rotation can compound infinitely in either direction depending on how the numbers go. You get the current rotation, modify an angle, then put it back, meaning next time it'll have the new adjusted values before rolling again

[gray arrow]

oh damn you right

[polar acorn]

Add on to the fact that getting the eulerAngles does not necessarily mean you'll get back the same vector you put in, the Z is not always going to be the same. If there's a "better" way to represent that orientation with values on X and Y with a 0 Z angle, it will

It's probably better to get the up direction of the FirePoint, then multiply that by a Quaternion.AngleAxis rotation about the Z-axis by some random amount of degress, and that'll get you a resulting rotation that applies that rotation to the FirePoint's up direction. Use that for your bullet's rotation and velocity instead.
https://docs.unity3d.com/ScriptReference/Quaternion.AngleAxis.html

[swift crag]

directly manipulating euler angles is rarely a good idea

[gray arrow]

could you tell me how to write this as code please? im quite new to unity and im still grappling with all the ideas of vectors

[swift crag]

you can multiply a quaternion with a vector to rotate the vector.

Quaternion.AngleAxis(45, Vector3.forward) is a rotation by 45 degrees around the Z axis.

[uncut dune]

I asked in unity talk but I think it fits way better here now that I think about it. Is there a variable type to store a function?

[swift crag]

yes, those are what we'd call "delegate" types

System.Action can hold a function that takes no arguments and returns nothing

System.Func<T> holds a function that takes no arguments and returns T

[uncut dune]

any void function?

[swift crag]

Both can have extra generic type parameters added to represent functions that take arguments

[swift crag]

With zero arguments.

System.Action<int, float> is a function that takes an int and a float and returns void

[uncut dune]

only?

[swift crag]

Correct.

https://learn.microsoft.com/en-us/dotnet/api/system.action?view=net-7.0
https://learn.microsoft.com/en-us/dotnet/api/system.func-1?view=net-7.0

[hollow zephyr]

use of gameObject in MonoBehaviour script leads to NullReferenceException

[uncut dune]

great to know thank you

[uncut dune]

also can I make it choose a function from the editor?

[swift crag]

You want UnityEvent for that.

You cannot assign delegate types in the inspector.

[uncut dune]

I was thinking maybe a way around was making a string and writing the name of the function for each gameobject

string();

could I do that?

[uncut dune]

I was afraid of that

[uncut dune]

unityEvent

I'll give it a search

[swift crag]

That would work with something like Invoke, which tries to call a method on a component by name

i would suggest using UnityEvent if you can

[uncut dune]

never used it before so I would need to make a little bit of research

[swift crag]

it's what Button uses

[uncut dune]

ohhhhhhhhh

that makes sense

I was trynna get something close to animation events

[swift crag]

It lets you assign references to any unity object and pick a method to call

[uncut dune]

are there any downsides to that?

compared to calling it directly in the script

[swift crag]

The methods you invoke with a UnityEvent can't return values. They have to return void.

https://docs.unity3d.com/ScriptReference/Events.UnityEvent.html

[polar acorn]

The added complexity of having to assign it in the inspector and thus adding a "second place" you have to check to get the full grasp of what a script can do

[swift crag]

It can't be statically analyzed

[polar acorn]

But you gain in modularity being able to use the same code to do different things

[swift crag]

You can ask your IDE "where does this function get used?"

but it will have no clue about UnityEvents

because nowhere in your source code is that method called

[uncut dune]

yah thats what I was trynna do

basically I have enemies and an enemy script

and I wanted some of them

to have special effects

so I was going to do it like that

[swift crag]

UnityEvent is a good fit for "when X, do Y"

[uncut dune]

pretty simple effects so I would only need to call a void

[swift crag]

this sounds like such a situation

you don't "call a void"

you call a method that returns void

[gray arrow]

how is this code? it says i cannot multiply Vector3 by Quaternion but im sure that is an easy fix, so do I have the right idea you were going for or am i doing it all wrong?

void shoot()
    {    

        float randomAngle;

        if (Input.GetKey(KeyCode.Mouse1))
        {
            randomAngle = Random.Range(-bulletSpreadADS, bulletSpreadADS);
        }
        else
        {
            randomAngle = Random.Range(-bulletSpreadHipFire, bulletSpreadHipFire);
        }

        Vector3 bulletOrigin = FirePoint.position;
        Vector3 bulletRotation = FirePoint.up * Quaternion.AngleAxis(randomAngle, Vector3.up);
        
        GameObject bullet = Instantiate(bulletPrefab, FirePoint.position, Quaternion.Euler(bulletRotation));
        Rigidbody2D rb2d = bullet.GetComponent<Rigidbody2D>();
        rb2d.AddForce(FirePoint.up * bulletForce, ForceMode2D.Impulse);
    }
}

[swift crag]

You can pass several arguments with UnityEvent

[swift crag]

Wrong order.

[uncut dune]

ok thank you thats good to know

[swift crag]

Quaternion times Vector3

[uncut dune]

can I pass none also?

[polar acorn]

Quaternion times vector, not vector times quaternion. When you're in four dimensions, order matters

[swift crag]

Yes.

[uncut dune]

ok that sounds amazing

[swift crag]

Quaterion.AngleAxis(45, Vector3.forward) will rotate whatever you multiply it with by 45 degrees around the Z axis

the Z axis points into the screen in a 2D game, generally

so, suppose you replaced 45 with a random angle...

[polar acorn]

Also you want to rotate about the Z axis, so it'd be Vector3.forward

[swift crag]

using Vector3.up would rotate your vector around the up-down axis, which would spin it out of the 2D plane entirely

you'd be shooting at the player :p

[gray arrow]

ok it works, the bullet sprite goes the correct direction, but the bullet is flying sideways, how do i make the bullet sprite change direction

[jolly igloo]

Does anyone have a tutorial about monopoly in unity?

[gray arrow]

as in the sprite is rendered facing the wrong way

[rich adder]

youtube it

its not gonna easy as beginner though

[jolly igloo]

Ok

[polar acorn]

Set the bullet's transform.up to the direction it's moving in

[azure zenith]

I have made a prefab as PowerCellCollectible. Shouldn't 1, 2, 3, 4 be child element?

[gray arrow]

how do i do that??

[polar acorn]

With =

[rich adder]

why would they

[polar acorn]

Why would they

[gray arrow]

so i just do bullet.transform.up = bulletRotation?

[swift crag]

Yes.

It's not a read-only property

you can both get and set it

[azure zenith]

I am wanting to add a box collider but I am thinking that if I add it to powerCellCollectible then I will not have to do it for the rest

[swift crag]

you'd...add it to the prefab

now every instance will have a box collider

[azure zenith]

Exactly

[rich adder]

as long as you apply the changes to the prefab it wil propagate for all

[azure zenith]

I am not sure if I have made a prefab

[gray arrow]

now all the bullets are invisible, im assuming that im rotating them around the wrong axis or smth

[rich adder]

if its blue its a prefab, yours looks like a prefab variant

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

[polar acorn]

Possible. Try debug logging the direction when you fire

[gray arrow]

here is the code i changed since i last posted the whole thing here:

GameObject bullet = Instantiate(bulletPrefab, bulletOrigin, Quaternion.Euler(bulletRotation));
        bullet.transform.up = bulletRotation;
        Debug.Log(bulletRotation);

[swift crag]

That rotation you created on line 1 is nonsense

bulletRotation is a direction

Just use Quaternion.identity to give the bullet no starting rotation

[uncut dune]

I dont need to add a listener if my unityevent is serializeField right?

[swift crag]

you add listeners through code if you want to add listeners...through code

You don't have to do anything for the ones you added in the inspector

[uncut dune]

ok I was just wondering that

[gray arrow]

i figured since im so bad at this ill just send the whole function again so people can see better what ive done wrong haha

void shoot()
    {    

        float randomAngle;

        if (Input.GetKey(KeyCode.Mouse1))
        {
            randomAngle = Random.Range(-bulletSpreadADS, bulletSpreadADS);
        }
        else
        {
            randomAngle = Random.Range(-bulletSpreadHipFire, bulletSpreadHipFire);
        }

        Vector3 bulletOrigin = FirePoint.position;
        Vector3 bulletRotation = Quaternion.AngleAxis(randomAngle, Vector3.up) * Vector3.forward;
        
        GameObject bullet = Instantiate(bulletPrefab, bulletOrigin, Quaternion.Euler(bulletRotation));
        bullet.transform.up = bulletRotation;
        Debug.Log(bulletRotation);
        
        Rigidbody2D rb2d = bullet.GetComponent<Rigidbody2D>();
        rb2d.AddForce(FirePoint.up * bulletForce, ForceMode2D.Impulse);
    }

[swift crag]

replace Quaternion.Euler(bulletRotation) with Quaternion.identity.

You are trying to interpret a direction as euler angles

[gray arrow]

surely that will remove the random aspect of the shooting?

[swift crag]

No. That's what the next line does.

[gray arrow]

ah i see

now all the bullets are really small though

[swift crag]

I noticed that you aren't using bulletRotation when adding force

This will make every bullet fly in the same direction.

hang on, things are mixed up here

I see why it's partially wrong.

[azure zenith]

Is there a difference?

[swift crag]

okay yeah that's all wacky

Vector3 bulletRotation = Quaternion.AngleAxis(randomAngle, Vector3.up) * Vector3.forward;

This is wrong for two reasons.

One: you are using Vector3.up as the rotation axis. This is spinning around the up-down axis. That is wrong.

[rich adder]

yes I sent docs explaining the differences

[swift crag]

You need rotate around the Vector3.forward axis.

Two: You are multiplying this rotation by Vector3.forward

This is applying a random rotation to a vector pointing out of the screen

I don't think you wanted to do that.

I think you wanted to do this:

Vector3 bulletDir = Quaternion.AngleAxis(randomAngle, Vector3.forward) * FirePoint.up;

This will randomly rotate the fire point's up direction

The rotation will spin it around the Z axis

[gray arrow]

ok i have changed all of the things you said

[swift crag]

you can now use this direction to:

• set transform.up on the bullet
• add force to the bullet

[gray arrow]

i believe its working but instead of changing the directions that the bullets fly it changes the rotation of each bullet

[swift crag]

Yes, because you also need to use this vector when adding force

Currently, your force is not random.

you'll always fire in the direction of FirePoint.up

[gray arrow]

so i should do rb2d.AddForce(bulletRotation * bulletForce, ForceMode2D.Impulse); instead?

[swift crag]

Correct.

bulletRotation is a bad name, by the way

It sounds like it should be a rotation value

It's not. It's a direction.

bulletDirection or bulletDir would be appropriate

[gray arrow]

ok i changed it i see why its confusing

[swift crag]

It's important to make it clear how to interpret a Vector3

• as a position
• as a vector (whose length matters)
• as a direction (whose length doesn't matter)
• as euler angles
• as a velocity
• ...

[gray arrow]

yes i think i need to do a bit more research on them ha

im very clueless

anyways it works now thanks bro

[polar acorn]

Cursed applications for Vector3:

• Health, Mana, Stamina
• Hips, waist, bust
• Three unrelated numbers you kinda wanna group for whatever reason
• Scientific notation whole part, decimal part, power of 10

[swift crag]

I want Vector1

it'd make things more consistent

[polar acorn]

How about instead of null we have a Vector0

[swift crag]

    public float Vec1(float t)
    {
        t *= scale;

        return noise.snoise(xVec * t + xOffset);
    }

    public Vector2 Vec2(float t)
    {
        t *= scale;
        
        return new Vector2(
            noise.snoise(xVec * t + xOffset),
            noise.snoise(yVec * t + yOffset)
        );
    }

unit type! unit type!

a zero-tuple is indeed a valid way to represent a type that only has one value

[gray arrow]

i have no idea what is happening anymore but i love it

[swift crag]

wait until you find out about the bottom type

˔

oh my god the tack is so small in discord

it's supposed to look like this

[gray arrow]

damn

[swift crag]

the bottom type has zero values, and is a subtype of every other type

[gray arrow]

so whats the point of it then

[swift crag]

it's the return type of a method that never returns in some languages

you can never get it, so the method must never return, by definition

never in typescript, for example

C# lacks such a type

(this is very esoteric)

confusingly, it's sometimes called the "void type", but this is different from C#'s void

void is very strange when you think about it. It's a type, but it has zero values, but it can still be returned

[gray arrow]

i think thats enough C# for one day

[swift crag]

you just can't use it anywhere other than a function's return type

it's funky

[faint sorrel]

hey idk if this is the right place to ask but i put "play automatically" off on my animation but it still plays automatically, how can i fix that?

[rich adder]

Hi again all, can someone please point me in the right direction as to what I'm doing wrong? This is really driving me nuts now.

Essentially I'm trying to make a suspension arm point at the height of the wheel. It works to an extent (the arm does rotate, but nowhere near enough). 😕

using UnityEngine;

public class SuspensionLookAt : MonoBehaviour
{
    [SerializeField] Transform wheelTarget;

    //Vector3 targetPosition;
    //float offset = 0.6523004f;

    // Update is called once per frame
    void FixedUpdate()
    {
        Vector3 targetDir = wheelTarget.position - transform.position;
        float angle = Vector3.Angle(targetDir, transform.forward);
        Debug.Log(angle);
        Vector3 newRotation = new Vector3(angle, 0, 0);
        transform.rotation = Quaternion.Euler(newRotation);

        //targetPosition = new Vector3(0, wheelTarget.position.y, 0);
        //transform.LookAt(targetPosition);
    }
}

I don't know why but I have such a weird blindspot when it comes to rotations 😕

Hi. Is there something like classes which some scripts can inherit from but that can stack up please? Like be able to set more than one thing there so one script also cointains something from another script

[rich adder]

you need interfaces

it doesn't "inherit " though

[glossy eagle]

that's the problem

[rich adder]

why do you need inheritence at all

Interfaces are great and keeps code modular

[glossy eagle]

because I need to run code on a specific script. Like, it is a script that gets the marked variables of "this" script and does something with them. The problem is that all the logic is using the "this" reference

[rich adder]

public class Enemey : Entity , IShootable, Iinteractble, ILoad etc

[modest dust]

If you want to inhert then just make a middle class inheriting from MonoBehaviour (WeaponsHolder) and inherit from that instead

Otherwise just use interfaces

[rich adder]

just be careful with inhertence though, it just ends up a dead end street or more mess than needs to be (sometimes)

[polar acorn]

Make WeaponsHolder extend MonoBehaviour and just inherit from WeaponsHolder

[glossy eagle]

that was just an example, the thing is that I need both the WeaponsHolder and another class called VariableManipulator in the same script

[polar acorn]

Then you cannot

Unless one of them is a parent class of the other, or an interface

[glossy eagle]

that's why I was wondering if there was something that can inherit more than one thing

[summer stump]

Chained inheritance is possible. Multiple inheritance is not

[glossy eagle]

oh ok

[summer stump]

Interfaces are the only way around that
Which is not really inheritance the same way of course. More of a promise of implementation

[glossy eagle]

well lemme try one thing rq. Edit: nvm doesn't work haha, thanks tho, I will have to try those solutions

[modest dust]

Wait, so what's the issue with using interfaces anyways

Provide some more info on what you're trying to do

            // Check if the current GameObject is bigger than the other GameObject
            if (mySize > otherSize)
            {
                Debug.Log("I ate the other GameObject!");
                // "Eat" the other GameObject (destroy it)
                Destroy(other.gameObject);

                // Increase the size of the current GameObject (optional)
                transform.localScale += Vector3.one * 0.1f; // Increase the scale by 0.1 units
            }
        }
    }
}

it also only works if they have the tag Car or Obstacle

[wintry quarry]

Add more logs and check where the code is getting up to

for example is OnTriggerEnter itself even running?

"doesn't work" is quite vague

[languid spire]

gpt code

[rich adder]

you put the tags to be only condition

it also only works if they have the tag Car or Obstacle

literally checking only if its car/obs

[polar acorn]

The Three Commandments of OnTriggerEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt tick isTrigger on at least one of them
3. Thou Shalt have a 3D Rigidbody on at least one of them

[amber spruce]

if (mySize > otherSize)

[glossy eagle]

Like, with interfaces I couldn't access the methods inside it because they were already like defined

[amber spruce]

nope

[polar acorn]

Actually interfaces are the opposite. You can't define them in the interface, you have to implement them on the scripts that use it

[amber spruce]

using UnityEngine;

public class EatObjects : MonoBehaviour
{
    void OnTriggerEnter(Collider other)
    {
        Debug.Log("I have collided with something!");
        // Check if the GameObject has collided with another GameObject
        if (other.CompareTag("Car") || other.CompareTag("Obstacle"))
        {
            Debug.Log("I have the tag");

            // Get the size of the current GameObject and the other GameObject
            float mySize = transform.localScale.magnitude;
            float otherSize = other.transform.localScale.magnitude;

            // Check if the current GameObject is bigger than the other GameObject
            if (mySize > otherSize)
            {
                Debug.Log("I ate the other GameObject!");
                // "Eat" the other GameObject (destroy it)
                Destroy(other.gameObject);

                // Increase the size of the current GameObject (optional)
                transform.localScale += Vector3.one * 0.1f; // Increase the scale by 0.1 units
            }
        }
    }
}

none of the debugs happen

[polar acorn]

#💻┃code-beginner message

[amber spruce]

whats number 2 mean like how would i do that

[polar acorn]

You would tick the box that says isTrigger

on one of them

[summer stump]

To use OnTrigger you need a trigger.
Otherwise use OnCollision

[glossy eagle]

then I don't even know what I was doing because I was doing something like

public void UpdateInspectableVariableValue(string variableName, string newValue)
    {
        Type type = GetType();
        FieldInfo field = type.GetField(variableName, BindingFlags.Public | BindingFlags.Instance);
    }

With no errors or anything

[polar acorn]

What are you even trying to do here

[glossy eagle]

basically set the variable value just by knowing the variable name

[polar acorn]

You probably shouldn't use reflection in a game, it's quite slow and very error prone. If you want to get a variable by name its probably better to store it in a dictionary

[glossy eagle]

Tbh, at first I was going to do that, and I indeed did start with just referencing the variables. But once the number of variables I have to modify in-game with the UI increases, the work and chaos behind every single addition to a MissionEditor increases exponentially😅

[ashen ferry]

u change that variable in same class u got that method in worst case shoulda been a switch or something

[glossy eagle]

what?😅

[ashen ferry]

    private string var2;
    
    public void UpdateInspectableVariableValue(string variableName, string newValue)
    {
        switch (variableName)
        {
            case "var1": var1 = newValue; break;
            case "var2": var2 = newValue; break;
        }
    }```

as brittle as reflection but not reflection so a step forward

[glossy eagle]

hmmm

and how would that work with 100 different variables?

[ashen ferry]

damn thats a lot huh

[glossy eagle]

for every script that can be changed

[rich adder]

dictionary ?

[uncut dune]

does unityevent.ivoke() get called every frame if on update?

[glossy eagle]

and every time I want to add something new I have to manually all those variables

[glossy eagle]

like, the problem I was facing was the ability to add more things easily

[rich adder]

it should

[ashen ferry]

how do u store ref to a variable in dict

[uncut dune]

ok thank you

[glossy eagle]

Okay new question (sorry haha), is there a way to set a static value externally?

Like I have this inside a class:

public static VariableManipulator inst;

And I want to set that inst value from another script. Is that possible?

[wintry quarry]

of course

just set it

with =

It's not really good practice to have random puvlid static variables being set from all over the place though

gets very difficult to track

[glossy eagle]

why this then 😦

[wintry quarry]

vm is an instance

[rich adder]

doesnt make sense

[wintry quarry]

To set a static variable you use the class name

which is probably what your red squiggle is saying

VariableManipulator.inst = vm;```

[glossy eagle]

ahhhh okay mb

[wintry quarry]

but i don't understand why you would do it like this

[glossy eagle]

I'm so dumb lol

[wintry quarry]

why don't you do cs public static readonly VariableManipulator inst = new(); directly in the class

why have some other class initialize it?

Seems weird

[glossy eagle]

because otherwise a reference to the inst is called before it is acutally set

[wintry quarry]

you can also just call Setup directly in the constructor

[wintry quarry]

not possible the way I just showed you

[glossy eagle]

yeah that's exactly what I was doing but that was causing said problem

like I had this: ```c
if(VariableManipulator.inst == null)
{
VariableManipulator vm = new();

        vm.Setup();
    }

and then in the VariableManipulator script :
```c
public void Setup()
    {
        inst = this;
    }

but the code just after the if was called before the setup was done aparently

[slender path]

I have a problem and it is when I go to get the distance to the mesh to place objects, it happens before the mesh will load in and does not like it, I found out that i can't use while to fix this either

[wintry quarry]

yeah this is wrong

do it like my example

```  Why does pressing the "Crouch Key" sometimes not work, if you spam it?

[queen adder]

Is this code in FixedUpdate?

[twin bolt]

Yes

[queen adder]

Move it to update and it should behave better

[twin bolt]

Okay, thanks.

[queen adder]

Fixed Update is for Physics related stuff it's better to not check for Input in there

[abstract finch]

Vector3 movePos = hit.transform ? hit.point - _projectileOrigin.transform.position : ray.direction;
Running into an issue where the projectile moves at extremely different speed if there is a hit. Also I would like to note that I'm not using lerp.

[twin bolt]

Yep that completely fixed it, Thanks.

[queen adder]

Ofc brother!

[wintry quarry]

how do we go from movePos to direction here ??

yo need to share more code

also why is it called movePos if it's actually a direction vector?

[abstract finch]

sorry its a bit messy let me create a cleaner version

[wintry quarry]

just share the full script

[abstract finch]

Gun

    {
        Projectile projectile = Instantiate(_projectilePrefab);

        Ray ray = new Ray(_projectileOrigin.position, Camera.main.transform.forward + Calculations.GetSpread(_profile.Spread));
        RaycastHit hit = Calculations.Raycast(Camera.main.transform.position, Camera.main.transform.forward + Calculations.GetSpread(_profile.Spread));
        Quaternion startRot = hit.transform ? Quaternion.LookRotation(hit.point - _projectileOrigin.transform.position) : Quaternion.LookRotation(ray.direction);
        Vector3 moveDirection = hit.transform ? hit.point - _projectileOrigin.transform.position : ray.direction;
        projectile.SetUp(_profile.Damage);
        projectile.Initialize(_projectileOrigin.position, startRot, moveDirection, _projectileSpeed);
    }```

Projectile

    {
        transform.position = startPos;
        transform.rotation = startRot;
        StartCoroutine(Move(direction, speed));
    }
    private IEnumerator Move(Vector3 direction, float speed)
    {
        while (true)
        {
            transform.position += direction * speed * Time.deltaTime;
            yield return new WaitForEndOfFrame();
        }
    }```

[wintry quarry]

You're not normalizing moveDirection

so the magnitude is different when you do the subtraction

Vector3 moveDirection = hit.transform ? (hit.point - _projectileOrigin.transform.position).normalized : ray.direction;```

[abstract finch]

ill give it a shot

[wary sable]

is there a way / how would I Instantiate an animator controller transition between two states from code?

[wintry quarry]

using animator params

[swift crag]

"instantiate"?

the transition is not a unity object

are you trying to modify an animator controller at runtime?

perhaps you just want to manually switch to a specific state?

explain your use case.

[wary sable]

sorry I was using instantiate as a generic term not as the method name

[wary sable]

I was trying to make an attack system with many different / unique animations, and was trying to store the animations on their specific weapons instead of a massive state machine with 100s of transitions. to do that I need to be able to acess a blend tree in code, add motions to it and set a float param (all of which I have gotten working), I was just trying to make it a bit easier on myself and also create that blend tree from code aswell. (instead of setting one up on every single character that can use the weapon)... Though from what I understand I will also need a transition to that tree/state to get it to work fluidly with the rest of the animator

[swift crag]

at that point i'd just use animator.Play to manually enter states as needed

[azure zenith]

My OnTriggerEnter function is not working as it is supposed to collect an item on the floor

[wary sable]

I was a little hesitant to do that since I dont want to interrupt certain states IE jumping. Would I still be able to check if certain states are running?

[swift crag]

Sure.

[swift crag]

https://docs.unity3d.com/ScriptReference/Animations.AnimatorState-transitions.html you may be able to modify this

i dunno if this will mutate the asset

[sand star]

you should figure out the physics setting. you have to attach at least one rigidbody component and have to set the layers to collide.

[swift crag]

so you may want to instantiate the animator controller before mucking with it

[wary sable]

thank you, as always ❤️

[azure zenith]

Yes, I have a rigidbody component and a box collider component on the game object

[sand star]

you should set the layers of two gameobjects to collide.

[azure zenith]

Sorry, wdym?

[queen adder]

Hey Sam are you making a 2D or 3D game?

[azure zenith]

3D

[sand star]

and then you should consider this.

[swift crag]

okay, so the rigidbody is probably not falling asleep and preventing the triggers from happening

(that happens in 2D)

[queen adder]

Is trigger set on the box collider?

[azure zenith]

Yes

[queen adder]

Can we see the code?

Do triggers work at all? Like have u tried putting a print() or Debug.Log() in the trigger? Just to make sure triggers are at least working?

[azure zenith]

The trigger does seem to work

[sand star]

can you share your screen of physics setting window, and hierachy of two gameobjects including layername, rigidbody component, collider component~

[azure zenith]

Yes, also only my object I want to collect had a box collider

That is from the collectible item

What do you guys think?

[wintry quarry]

the blue line on the left indicates this is a prefab override

shouldn't it be set as a trigger in the prefab itself?

[queen adder]

Share the code

It could be like a really simple mistake in ur script

[azure zenith]

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("CollectibleCell"))
        {
            Debug.Log("Trigger entered by CollectibleCell.");
            Destroy(gameObject);
        }
        else
        {
            Debug.Log("Trigger entered by something else.");
        }
    }

[wintry quarry]

so what is printing?

[azure zenith]

Printing?

[queen adder]

Whats the console saying

[wintry quarry]

the log

what is logging>

You put the log statements there for a reason, no?

[azure zenith]

Oh

[wintry quarry]

ok so

the tag on the object is wrong

seems straightforward

[queen adder]

Does ur item have the correct tag?

I try to avoid using tags i usually use interfaces for items if ur familiar with interfaces

[frank light]

how do I use the Character Controller component to move in the direction the object is pointing and not straight up or down.

[azure zenith]

The tag is correct

[queen adder]

Show us the tag

[wintry quarry]

clearly not

[rich adder]

transform.forward
cc.Move(tansform.forward * speed * Input.GetAxis("Vertical") * Time.deltaTime
(Don't copy just an example - don't do inline like this)

[wintry quarry]

yeah but this is probably not the object you are colliding with

[azure zenith]

The cell should destroy when the player touches it

[ashen ferry]

I want to instantiate cameras and set render textures for them can I assign this in code?

[queen adder]

right but the trigger isnt detecting the cell

[ivory bobcat]

Debug.Log($"{name} was hit by {other.name} that had a tag of {other.tag}", other);```

[queen adder]

Wait

I think know what ur doing

[wintry quarry]

ok well; it's going to need the proper tag for that to work

show the whole inspector for the object

with the collider and the tag etc

[queen adder]

Is ur cell the one with the trigger?

[wintry quarry]

also printing the tag you hit in the log is a good idea

[azure zenith]

Yes

[queen adder]

It should check the players tag

Ur doing the opposite

[wintry quarry]

prove it

[queen adder]

Ur checking if the cell entered the cell

[wintry quarry]

wait is this cript on the collectible itself?

Why would it need to check its own tag?

[azure zenith]

Yes

[wintry quarry]

Yeah it should be checking for the player

your code makes no sense

[echo dove]

Hi guys, my bullet is a prefab and I do not know how to give it commands from an object that isn't it just won't let me. That's why when the player stops (all stuff should be slowed down) the bullet doesn't. How can I fix this?
https://hatebin.com/hfwumdsqek (player code)
https://hatebin.com/vrfmksygyo (bullet code)

[rich adder]

https://unity.huh.how/programming/references/prefabs-referencing-components

[queen adder]

Change CompareTag() to accept the players tag

[wintry quarry]

gonna be honest watched your videos and read your coder and I have no idea what you're asking

[echo dove]

Ik that but I am asking how can I change it

[wintry quarry]

what "command" are you trying to give?

[echo dove]

My player code

[wintry quarry]

What object are you trying to give it from and to?

[echo dove]

I cant give it to my bullet prefab

[wintry quarry]

what about your player code

give what to the bullet>

[echo dove]

And it can't get a variable from the player code

[wintry quarry]

Where is the code that spawns the bullet?>

[echo dove]

script

[wintry quarry]

It's not in the script you shared

wht do you mean "give script"?

Be speciific please

what information are you trying to share?

for what purpose?

[echo dove]

I want to give the bullet the player script so that it can access code from the player

[wintry quarry]

why

what are you trying to accomplish

[echo dove]

Because when my player has velocity.magnitude = 0 all slows down to 0.1x

ANd I want to have a bool

[wintry quarry]

that code isn't anywhere in the scripts you shared

[echo dove]

when it is true that means

[echo dove]

no

[wintry quarry]

You need to share the code that is relevant to the problem

this isn't it

where is the slow motion stuff happening?

[echo dove]

player code

[wintry quarry]

this is not something the bullet needs to care about

[echo dove]

In the second video I show

[frank light]

i did that and now it works, it just wont let me control it anymore and moves upward with out any input.

 Vector3 move = new Vector3(0, Input.GetAxis("Vertical"), 0);
 characterController.Move(transform.up * Time.deltaTime * Speed);

[wintry quarry]

why aren't you just using Time.timeScale?

[magic stream]

Hi, currently i'm trying to make sorting work but it doesn't work xd Tilemap with trees and stuff is in same layer as player sprite.

[echo dove]

What is that

[wintry quarry]

It's the way you should be slowing the game down

[echo dove]

But how can I give the function to tell the bullet that the player isn't moving

[rich adder]

wait is this 2D? why are you doing up..

[wintry quarry]

you don't need to

[swift crag]

well, you don't use move anywhere in line 2, so of course it ignores your input!

[wintry quarry]

set time scale to 0.1

and everything will be slowed

[echo dove]

wdym

[wintry quarry]

Time.timeScale = 0.1f;

[echo dove]

okay lemme try

[frank light]

would i just add move * or do i have to do something else?

[rich adder]

Having move there is kind of important lol thats what makees it not move because Input = 0 then everything is 0

[queen adder]

@magic stream

[rich adder]

stuff * 0 = 0

[azure zenith]

Alright, I changed the tag to main camera which is the player so now it should be working? Should I nowmove the script from the cell to the player?

[queen adder]

Look up auto sorting on youtube

[magic stream]

i've tried everything

[queen adder]

Have u tried what i just reccomended ?

Its a Render Feature in Unity

I dont know if thats the correct term but basically Uinty has already coded this for u

[magic stream]

i know

[queen adder]

U just have to enable it

So uve tried it then?

Im not talking about the sprite Renderers layer field

[frank light]

this doesnt work, am i putting move in wrong?

[magic stream]

but issue is probably that my project isn't URP, maybe it doesn't make any difference idk xd

[queen adder]

If ur projects not in URP....

Then idk ive tried coding a system like that myself but its a pain

[echo dove]

what is dis guys...

[ivory bobcat]

Are you randomly doing stuff? Maybe lookup a tutorial

[echo dove]

it sends me to some randoom place

[rich adder]

how come you're doing .up ?

[swift crag]

have you read the error message?

[ivory bobcat]

Ideally, it'd simply be the direction multiple by speed and delta time.

[frank light]

i want it to move in the direction it is pointing upwards, and it did but it didnt take in my input.

[echo dove]

Yep I don't get

[wintry quarry]

the Scene object you passed into MoveGameObjectToScene was not a valid scene

[echo dove]

It doesn't even tell me what object

[queen adder]

@azure zenith the player is the camera?

[wintry quarry]

Wherever you got it from was wrong

[azure zenith]

Sorry no, the player is the player lol

Also, I get the correct log statement now

[queen adder]

Whats the players tag

Ok good! Sorry

[azure zenith]

It doesn't disappear though but I'll see why

[echo dove]

It doesn't slow everything down

[wintry quarry]

what isn't slowing?

[echo dove]

My bullet

[azure zenith]

Thank you all for helping

[rich adder]

this I think gives you an error.

[wintry quarry]

Since your bullet is simply moving via rigidbody velocity, it should indeed slow

[rich adder]

@frank light did you check console ?

[wintry quarry]

maybe you never set the time scale

[echo dove]

lemme show you a video

I did

[frank light]

it gives me a syntax error

[rich adder]

yes you can't multiply two vectors

[swift crag]

you can't just mash together random variables

[wintry quarry]

show the code

}

LIke this?

[swift crag]

stop and think about what you are doing.

[rich adder]

@frank light you have to use move.y

[frank light]

instead of move?

[rich adder]

since its a float

[rich adder]

yes you can't do move * transform.up if move is vector3
so you need move.y

[frank light]

ok

thanks

[echo dove]

Ohh mb i put the code in bullet not player sr

[wintry quarry]

yeah it needs to go in the slowmo function

[buoyant knot]

isn’t transform.up a vector 3

[rich adder]

exactly

you can't multiply 2 vectors

[buoyant knot]

oh i see what he’s going for

[frank light]

thank you it works now navarone you are helpful

[buoyant knot]

i also recommend you separate player movment from player life/death code

[echo dove]

yep mb

[buoyant knot]

both player movement and life/death can get really complex as you build in more features, and the two don’t have much to do with each other, besides death asking movement to just hard stop

[rich adder]

me looking back at my earlier projects with classees spanning over 800 lines long xD

what the hell was single responsibility ?

[buoyant knot]

those are the worst

i inheritted code that used a fuckload of booleans… instead of an enum

[rich adder]

its like looking at an old high school photo with bad haircut and clothes and thought it was "cool"

[buoyant knot]

untangling that was a mess

[queen adder]

enums are underrated

[heady nimbus]

Is there a way to serialize a field to assign a Scene to a reference?

I'm trying to use 1 script to handle zone transitions from different locations in a scene and I'm trying to work out the best way to handle the whole "door A goes here, door B goes here" without hard coding or creating a bunch of specific scripts for it

[buoyant knot]

not really

[rich adder]

sounds like you need to re-think this system

[buoyant knot]

what I have done is make a static class with a bunch of public constants, where each constant corresponds to the specific number of a given scene

and also, you want extremely few scenes in a game

[queen adder]

Oh i used strings for mine^

[buoyant knot]

like, single digit

[queen adder]

Wait really?

[buoyant knot]

you can’t use strings. you need an int for build index

[queen adder]

You can load scenes by name?

[buoyant knot]

constants let you call those ints by using something like SceneIndices.MainMenu

[heady nimbus]

First time I've heard that

[buoyant knot]

and then it spits out the scene index for main menu, which is 0

ok, you want extremely few scenes

i’m telling you now

[queen adder]

Why tho

Is there like a specific reason or? Just curious

[polar acorn]

Actually I've found most people drastically underutilize scenes. Most people could stand to use more scenes

[heady nimbus]

Well I mean if there's no way to do that then I guess I do. I'm just starting to work on it, like today. Lol

[buoyant knot]

because every time you change scenes, you have to deal with everything getting destroyed, and managing references to/from things that should/shouldn’t be destroyed

[queen adder]

I mean....yeah

[buoyant knot]

and that’s a pain in the ass

[queen adder]

But what about stuff you dont want in a scene? It would make sense to get rid of it

[buoyant knot]

what stuff do you not want in a scene

[rich adder]

Load Additive 😛

[polar acorn]

Not with proper comparmentalizing of data and additive scene loading

[heady nimbus]

If I'm completely changing zones in a platformer, I don't want the old zone assets sitting around the entire time

[queen adder]

Level Based games? Neon White for example (Made in Unity) has over 200 levels

[buoyant knot]

exactly. That’s why I load a level file into the scene, so the scene can load everything about the new level

[queen adder]

I highly doubt they combine levels into singular scenes

[summer stump]

Additive scene loading is goated.

[rich adder]

Even Open world games are split into multiple scenes

[buoyant knot]

if a lot of the assets you put are manually placed, then you probably want additive scene loading

[rich adder]

makes it easier to collab on map

[polar acorn]

A scene should be thought of as a "loading point". If you have more smaller scenes you can dynamically load and unload them. For example, Metroid Prime has something analogous to "scenes" for each room in the game. When you shoot a door, it loads that room async and additively. When the door shuts behind you, it unloads the old room

[ivory bobcat]

This has the cost of requiring some load buffer/scenes.

[polar acorn]

So you'd have hundreds of scenes for a game like that

[rich adder]

take a look at how they made Firewatch, its split into multiple senes

[queen adder]

Yeah im familair ^^

[heady nimbus]

Load additive was the next thing I have questions about. I read recently a solution that involved creating a "base" scene that has all your don't destory stuff like player, cameras, audio, etc, then just loading additive scenes around it? Is that common?

[queen adder]

Ive seen there talks

Have u seen the fucking animation system for that game

Its insane

[rich adder]

bonzai nest

[buoyant knot]

it depends on how you make everything. A scene is like a giant mega prefab

[queen adder]

Ive never heard off additive scene loading but it sounds interesting

[swift crag]

you probably don't want many exclusively loaded scenes if you don't have nice distinct levels, since switching between those is, indeed, going to make everything go away

[rich adder]

DDOL just measn they live in their own scene

[swift crag]

i mean, just using DontDestroyOnLoad is already doing additive scene loading

[queen adder]

Thats what i figured^^

[heady nimbus]

Ok, that makes sense actually

[swift crag]

it punts the object into a scene that never unloads

[queen adder]

I was wondering why not just use DDOL

Besides singletons

[arctic ridge]

Hi there, i am currently trying to make a script so that when the player touches an object, it increases a varaible in the same script by one. However, i am having some trouble doing so. I have attatched an image with my code as well

[queen adder]

IS ur game in 2D or 3D?

[arctic ridge]

3D

[queen adder]

Also....

Shouldnt that be a int instead of a float?

[polar acorn]

The Three Commandments of OnTriggerEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt tick isTrigger on at least one of them
3. Thou Shalt have a 3D Rigidbody on at least one of them

[buoyant knot]

In general, more scenes = more problems. So you want to avoid separate scenes unless you have a good reason.

[queen adder]

Hes seen this question probably a million times lmao

else null??

[arctic ridge]

I'm not sure. I have some code later so the player speed is changed by a modifier that is 1+(speed items * 0.2)

[arctic ridge]

Thanks

[queen adder]

Ohh i see

why the else null?

That doesnt even look like it should compile

[wintry quarry]

i am having some trouble doing so
What kind of trouble?

[arctic ridge]

I grabbed this code from another project, and it was set to do something else. Eventually i am going to have the triggering item dissapear as well

[arctic ridge]

One second

[eternal needle]

There is so much wrong with this code the more I look

[queen adder]

Yeah like im confused

[polar acorn]

Show the BloonData for a green balloon

[eternal needle]

You've ended the method and if statement with a semicolon

[wintry quarry]

you have a lot of problems with your code:

• You have a semicolon after your if statement
• you have an else attached to nothing
• you have a statement that just says null;???

[queen adder]

Bro lmao

[wintry quarry]

looks like basic compile errors

[arctic ridge]

Tbh im not entirely sure what im doing

[wintry quarry]

first step is to configure your IDE

[polar acorn]

Okay, now double click that blue prefab and show me the inspector of the thing it opens

Okay, now double click that BlueBloon variable and show me the inspector of that one

[buoyant knot]

First, it might help to call a public method Death() instead of Destroy(gameObject). This way you aren’t worried about things not being arround when you need them

[polar acorn]

Okay, and you've been clicking on these objects in the variables, right? Just to make sure you don't have two things named BlueBloon for example

Just wanted to make sure

Are you actually getting an error?

If so, you should post that

Can you show what the console looks like after killing a green balloon, and then the blue balloon it makes?

[arctic ridge]

Im on mac using VS Code, and im not really seeing how to configure the ide

[arctic ridge]

Im going throught the jetbrains rider, but i dont know how to install it

[buoyant knot]

why do you even need a last position variable?

[polar acorn]

Why

Why are you going through Rider if you're using VSCode

Nah, I just want to see what those logs say

If you have logs that aren't in this script, maybe disable them

[arctic ridge]

Because that link is under VS Code

Is there a better way?

[polar acorn]

Did you try clicking on VS Code

[arctic ridge]

I think i misread that lmao

Thats on me

[heady nimbus]

The VS Code is not a HEADER that's a link

[arctic ridge]

🤦‍♂️

[heady nimbus]

Lol, I mean... I can KIND of understand that one

[buoyant knot]

again: why do you need a last position variable

[polar acorn]

I'm not seeing anything ChildBalloon Position =

Are you sure there's no errors that are hidden

[arctic ridge]

I am also unsure how to pull up the preferences window on mac

[ivory bobcat]

Likely his instantiation uses a cache of position which isn't properly updated beyond the original bloon

[buoyant knot]

probably

[polar acorn]

Okay, so it is reaching that step

[buoyant knot]

also, you need to comment your code, dude. Move vs Move2 makes no sense

comment + better name

[arctic ridge]

I need to upgrade my unity version but my computer is SO slow

[buoyant knot]

why can’t you get that by transform.position?

when the bloon dies

[polar acorn]

Let's level up those debug logs, replace your function with this:

public void OnDestroy()
    {
        revive += 1;
        if (BloonData.Children != null) // Check if the balloon has any children
        {
            GameObject ChildBalloon = Instantiate(BloonData.Children, lastPosition, transform.rotation);
            Bloons ChildBalloonScript = ChildBalloon.GetComponent<Bloons>();
            ChildBalloonScript.revive = revive;
            ChildBalloonScript.lastIndex = lastIndex;
            ChildBalloonScript.lastPosition = lastPosition;
            Debug.Log($"{gameObject.name} has been destroyed. Spawning in {ChildBalloon.name} at position {lastPosition}");
        }
    }

[heady nimbus]

So instead of switching to small scenes for things like inside a house in town, would you suggest just additive load the scene else where in the existing scene and porting player/switching camera there?

Or just having the "interior" scenes built in the same scene space and jumping there when needed?

[buoyant knot]

additive load

i guess it depends on how big the inner house is

[ivory bobcat]

Or have inactive objects and enable them

[polar acorn]

Yes, and then do the same process, kill a green balloon, then the blue one, and look in the console for that section of logs

[heady nimbus]

Yea, they aren't big

[ivory bobcat]

If the scenes were designed separately, then you'd want to load them additively

[buoyant knot]

yeah, I would make a class to just log everything part of a given layer of loading

[ivory bobcat]

Instantiation isn't expensive (unless you're computing crazy stuff), GC collecting is.

[buoyant knot]

like one class that just has references to everything in the city. On load house, make them all don’t destroy on load, load house scene. Repeat

[arctic ridge]

My VS code was in safe ir untrusted mode, blocking soem pluggins. When i put it into trusted mode it says sign in to access VS code benefits as well and nowsome of my pluggins say preview, including Unity. Will this be an issue?

[rich adder]

unity plugin is still in preview yes

its normal

[arctic ridge]

Ok

[rich adder]

up to you if want to sign in or not to save ur settings

[arctic ridge]

Ok, thanks

[buoyant knot]

I always keep an entity ledger class

[heady nimbus]

I've only just started working on these additional scenes so I only have 1 so far, just trying to work out the best way to pull it in. It was also my first time using a tile set map specifically with these interior scenes so hopefully that doesn't mess things up. I'll try bringing it into the main scene a few different ways and see how things go. Thanks everyone

[buoyant knot]

EntityLedger singleton. Everything that spawns has a SpawnedEntityHandler, and logs itself to the entity ledger upon being spawned, and unlogs when despawned.

[wintry quarry]

instantiating in OnDestroy leads to sadness 😦

should do it in a separate Die() function instead

[polar acorn]

Looks like it spawned in the red one just fine.

[buoyant knot]

Makes it super easy to controlled destroy/despawn everything temporary in a scene

[polar acorn]

But also you have an error

What is it?

[buoyant knot]

agreed

[polar acorn]

Yes, that is one of the many follow-ups I'm going to suggest, along with changing all those prefabs of type GameObject to just be Bloons

Yeah, I think it's time we move into this problem sooner rather than later

You shouldn't be doing this in OnDestroy. You should make this function something like OnDeath() and manually call it before Destroying an object in code

so it doesn't get called whenever the scene changes

[buoyant knot]

in general, I try to do very little during OnDestroy because you don’t know how much shit has already stopped existing

[polar acorn]

It's a good place to unsubscrive from things

[wintry quarry]

You just need to be paranoid with if (thing != null) checks in OnDestroy

[buoyant knot]

i mostly use OnDestroy as an emergency: “make sure we unsubscribe and let everything know we are dead if every other check failed” sort of thing

normal death/despawn is handled through methods that get called before any Destroy calls go out

no

public event Action OnDeath;

public void Death() {
do whatever you need to do when you are dying;
OnDeath?.Invoke();
Destroy(gameObject)}

[polar acorn]

Rename your OnDestroy method to Death

[ivory bobcat]

The suggestion was made to simply avoid the OnDestroy callback.

[polar acorn]

and then manually call it when you defeat a balloon

[ivory bobcat]

This isn't merely to factor code into a different function, just to be clear.

[odd shale]

Can someone suggest me a way i can learn c# sharp for unity?

[polar acorn]

Check the pins

[buoyant knot]

factoring the code into a different callback lets you avoid using OnDestroy

[static cedar]

C##.

[buoyant knot]

yes

[polar acorn]

Correct. They still do that, but now they should also call Death() on that object

[buoyant knot]

it’s not the most spaghetti, but you should do better before you are too far gone

[buoyant knot]

no. they call Death(), not destroy at all. Death is responsible for calling destroy

[ivory bobcat]

Understandable but I'm clarifying that the below isn't what we're simply trying to achieve cs void OnDestroy() => Death();🥹

[polar acorn]

It wouldn't matter either way, as long as it dying and it being destroyed are separate things

[buoyant knot]

yeah that’s wrong

[buoyant knot]

Death should centralize it. It isn’t the projectile’s job to handle destroying the thing. It’s the bloon’s job to know what to do when it’s supposed to die

projectile just needs to notify bloon about this request to die

it sounds semantic, but I think it is important

[elfin eagle]

Hi how do I transfer data into one scene to another? Like lets say I have 2 gold coins in one scene and I want to transfer that to a different scene

[languid spire]

DDOL or ScriptableObject

[buoyant knot]

GetComponent<BloonScript>().Death();
that is all projectile needs to do

[ivory bobcat]

Not sure, I'd just do the below in a health property cs _health = value; if (_health < 1) { Dead(); Destroy(gameObject);//or decommission to object pool }

[elfin eagle]

whats DDOL?

[languid spire]

Dont Destroy On Load

[polar acorn]

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

[odd shale]

What pins

[polar acorn]

in this channel

[ivory bobcat]

The pinned messages of this discord channel

[odd shale]

Ohh

Thankss

[elfin eagle]

thx

[polar acorn]

Is the BloonsScript on the object this script is on?

[ivory bobcat]

You'd probably still want to call destroy on the bloon

[wintry quarry]

it's happening in OnDeath

[ivory bobcat]

Ah alright

I wasn't aware of the progress that's been made

Probably whatever's being destroyed doesn't have the component

[wintry quarry]

should be collision.collider.GetComponent<Bloons>()

not just GetComponent<Bloons>()

[ivory bobcat]

And what line is 31?

[polar acorn]

Does this object have a Bloons script on it

[ivory bobcat]

It definitely isn't related to code - #💻┃unity-talk

[arctic ridge]

Ok, i wasnt sure if that fit. Thanks

[amber spruce]

how would i make it so when i collide with something a certain thing only happens if im bigger then them

[polar acorn]

You are currently trying to get the Bloons component from this object, and since it doesn't have one, that's your error. You probably want to get the Bloons component from the object you collided with

[ivory bobcat]

if bigger than target
    do certain thing```

[amber spruce]

no like actual code lol

[polar acorn]

If they have colliders, get the colliders bounds. Then, you can get bounds.size to get the width and height. From there, decide if you want to know if the area is bigger (multiply size.x and size.y before comparing) or if you want it to be bigger on at least one axis (check size.x and size.y separately)

[ivory bobcat]

Which part?
The on collision enter callback, size comparison or the do certain thing?

[amber spruce]

the size comparison

[ivory bobcat]

I'm assuming you've researched this are doing some sort of bounds comparison

[polar acorn]

Checking collider bounds lets you compare the size of objects even if their meshes have different scales

[amber spruce]

float otherSize = Mathf.Max(collision.collider.bounds.size.x, collision.collider.bounds.size.y, collision.collider.bounds.size.z);
float thisSize = Mathf.Max(transform.localScale.x, transform.localScale.y, transform.localScale.z);
 if (thisSize > otherSize * crushThreshold)
``` tried this is doesnt work

[polar acorn]

If you're using bounds, use bounds for both

Scale and size are not necessarily comparable

[amber spruce]

so how do i get my objects bounds

[polar acorn]

https://docs.unity3d.com/ScriptReference/Collider-bounds.html

[amber spruce]

aight thanks i gtg for a little

[keen dragon]

Can someone help me with this?
I'm copying a tutorial to learn movement... I don't think I did anything wrong, and all my attempted fixes kind of just break it more?

[wintry quarry]

you did something wrong

[azure zenith]

My game starts off with having 0 grenades. When I collect a grenade, it should increase the amount of grenades I have but I get an error: NullReferenceException: Object reference not set to an instance of an object

[keen dragon]

That's what I don't know

[rich adder]

is it a list ? its probably not initialized

[wintry quarry]

the first thing you need to do is finish configuring your IDE

[burnt vapor]

Your editor is not configured. Configure it first (see bot message below)

[eternal falcon]

💡 IDE Configuration

[keen dragon]

nooooo

[azure zenith]

It is an int variable set to 0

[polar acorn]

yeeeees

[rich adder]

show which line that error is

[polar acorn]

Show the line the error is on

[burnt vapor]

Try again, it saved a lot of headaches.

[wintry quarry]

you need to read the full error message which includes a filename and line number for the error

[azure zenith]

Okay, one sec

[polar acorn]

So what is powerCellCollectible.cs line 13

[keen dragon]

I trust windows with my life now, but visual studio sees no problems. only unity

[polar acorn]

shooterScript is null

[wintry quarry]

btw you are making lots of typos. That's why you need to configure your IDE:

if it was configured this would be underlined in red

you would also have autocomplete

[summer stump]

Because it is not configured 🤷‍♂️

[azure zenith]

It is set to 1 actually

[polar acorn]

shooterScript cannot be set to 1

Because 1 has no property named no_cell

Okay, so, the red one's invincible. Where do you destroy the balloons?

Get rid of lastPosition and use transform.position as the second parameter to Instantiate

[amber spruce]

should i do that in my script or make a seperate script for that

[polar acorn]

Well, you want to know this object's bounds in this script don't you

[amber spruce]

yeah just didnt know if it was meant to be a seperate one lol still new

[eternal needle]

Just wanna throw this out there since it seems you're making a btd clone. if you plan to add projectiles that do more than 1 damage, you're gonna have to add more to this method so that it checks how many layers to destroy. Having it go through each children is gonna be slow if something eventually can deal 10 damage

[amber spruce]

smth like this would work

m_Collider = GetComponent<Collider>();
m_Size = m_Collider.bounds.size;
float thisSize = Mathf.Max(m_Size.x, m_Size.y, m_Size.z);

[lament kernel]

do you mean skip through layers ie if the projectile is 2 damage a green balloon goes straight to a red balloon

[polar acorn]

[eternal needle]

Yes, in your current method this isnt possible. You could try to get the child of a child (doing this equal to the number of damage you do) but theres probably a faster alternative instead of going through what I assume is data on a prefab. Itd be better if you could have some function used to calculate which layer it should go to

[amber spruce]

how do i give a object a rigidbody but have it stay still

[polar acorn]

What are you adding a rigidbody for? Weren't you already detecting collisions?

[amber spruce]

well was gonna do it so i could disable its movement

but i guess i can just do another if for if its a car

[lilac crow]

hi everyone! 😄
can someone guide me please!
a week ago i start to code again and notice my IntelliSense has stopped working. 🥲
i looked around and notice unity removed the visualcode package and so on.. 🧐
i fixed it by installing the visual studio editor 2.0.22 for unity and unity extensions and c# dev and .net SDK 8 (i already had 6 and 7). 😉
BUT NOW it has stopped working again. 😖
i checked the prefrences and everything.
i thought it beacuse c# dev preview version so i installed it BUT it still not working. 😭
how should i fix it? 😟

``` my code

[polar acorn]

Well, you are taking the largest axis, what do you expect would happen

[summer stump]

I WAS wondering why you were using Max

[amber spruce]

so what should i use instead

should i use Min

[rich adder]

nice gpt code

[summer stump]

Compare the size of the bounds?

[languid spire]

what do you consider one thing must be to be bigger than another?

[amber spruce]

wdym

[polar acorn]

As I said, you're going to have to decide how you want to know when something is bigger

[rich adder]

it was a joke, because of your code comments

[summer stump]

Why min or max or anything? Don't you want size?

bounds.size

[amber spruce]

oh yeah i put my code into chatgpt to have it write comments for me makes it easier

[rich adder]

eh code should be pretty self explanitory what its doing

gpt comments are as useful as a car without gas

[amber spruce]

yeah i use bounds.size

[lilac crow]

I know i followed it last time and got fixed but it's not working again!

[summer stump]

You use it INSIDE max though... just don't, and compare it directly

[summer stump]

How long ago?

Could just need to regenerate project files

[lilac crow]

4 or 5 days ago

[summer stump]

Ok yeah. Go to External tools and click regerenerat project files

[amber spruce]

then there are errors though

[lilac crow]

I'll try it thank you. 🌹

[polar acorn]

Because otherSize is a float, and you're trying to set it to a tuple of three floats

Again, you're going to need to think about what makes something "bigger". How do you define "bigger"

[summer stump]

Why are you even trying that? What benefit would doing that have? That is breaking up the axes of the size and putting them in a tuple and trying to assign that to a float....

[amber spruce]

taller i guess

[polar acorn]

Okay, so that's the Y size

So check if the Y size is bigger than the other

[amber spruce]

basically if your bigger then you can obsorb the smaller thing

[polar acorn]

Define "bigger"

[languid spire]

so a 1m tall 1cm round pole can absorb a 50cm high 400km wide cube?

[amber spruce]

thats why idk what to do for it

[languid spire]

so think, it's your game, you decide

[polar acorn]

This isn't something we can answer. You need to decide what you want "bigger" to mean

[amber spruce]

alright thanks i can figure this out with this info

[polar acorn]

Once you know what "bigger" means, we can try to help with how to implement it, but we can't decide it for you

[languid spire]

so object volume

[summer stump]

What does "correct" mean for you?

[polar acorn]

So then work on making something to try it on

If you don't have anything that can run it then it doesn't matter if it's correct or not

[formal escarp]

as in uh. "it will work"

[polar acorn]

Well, right now it won't work, because it apparently does not exist

[formal escarp]

fair enough. ill code a raycasting and see

[summer stump]

It will work as written. As all code does.

hey so for my cars it works fine but if i try to do it to smth like a fire hydrant it doesnt work for it only difference between the 2 is model of course and the car has a car controller and a rigidbody

using UnityEngine;

public class CrushObjects : MonoBehaviour
{
    public float crushThreshold = 2f; // Size threshold for crushing
    Collider m_Collider;
    Vector3 m_Center;
    Vector3 m_Size, m_Min, m_Max;
    

    void OnCollisionEnter(Collision collision)
    {

        // Calculate the size of the colliding object
        //float otherSize = Mathf.Min(collision.collider.bounds.size.x, collision.collider.bounds.size.y, collision.collider.bounds.size.z);
        float otherSize = (collision.collider.bounds.size.y);

        // Calculate the size of the current object
        m_Collider = GetComponent<Collider>();
            m_Size = m_Collider.bounds.size;
            //float thisSize = Mathf.Min(m_Size.x, m_Size.y, m_Size.z);
            float thisSize = (m_Size.y);
            //float thisSize = Mathf.Max(transform.localScale.x, transform.localScale.y, transform.localScale.z);
            Debug.Log("This size: " + thisSize);
        Debug.Log("Other size: " + otherSize);

            // Check if the current object is bigger than the colliding object
            //if (thisSize > otherSize * crushThreshold)
            if (thisSize > otherSize)
            {
                // Crush the object by disabling its Rigidbody and Collider components
                collision.collider.enabled = false;

                // Optionally, you can add more crush effects or actions here

                Debug.Log("Object crushed!");
            }
        }
    }

[polar acorn]

Does the other object have a rigidbody

[amber spruce]

so the object colliding with it has a character controller does that act as a rigid body

[polar acorn]

No, but it does have its own callback instead of OnCollisionEnter

https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnControllerColliderHit.html

[amber spruce]

adding this ```csharp
if (hit.gameObject.CompareTag("Car") || hit.gameObject.CompareTag("Obstacle"))

[formal escarp]

i have a question guys. i have declared the var "hit" but its not in use. where should i uh or rather, how do i fix that? i searched on the microsoft thing and it explains how you get the error but not how to fix it. 💀

And im unsure if i should fix it "from" the rayray script or make a whole new script for "if you get hit X happens"

[ashen ferry]

its a warning u got variable u dont need if its like a parameter u need to include u can make it a discard "_"

[polar acorn]

If it's not being used then it doesn't need to exist

[formal escarp]

But i want it to use it so the rayray can hit stuff and eliminate it.

[polar acorn]

So then use it

[formal escarp]

😲

[ashen ferry]

[short hazel]

Assuming raycast. If you do not need to access info of what you hit, discard the out parameter.

if (Physics.Raycast(origin, direction, out _, distance, mask))
  // ...

[wintry quarry]

THere's also a version of raycast that doesn't have the out param

[formal escarp]

Alrighty. Thanks guys.

im going to drink a big glass of cola and keep on learning

[rich adder]

nuka cola?

Is there a best way to apply motion to a character for a 2d sidescroller? I've tried using addforce and changing the velocity of the rigid body separately and both just didn't feel like what I was looking for. Is this usually something that is done from scratch making your own system?

[rich adder]

I guess depends what you're after.
Dynamic rb are tricky but have their benefits, what exactly are you looking for ?

I found that using AddForce is better with Acceleration/Force mode

[kind cove]

Hollow Knight, responsive, fast

it's hard getting that feel while battling physics is what I am finding.

I feel like I am having a hard time finding a balance between weight, friction, etc

[rich adder]

thats usually the downsides. I think thats a custom controller

make custom controls, the hard part is learning about the essentials like coyote time and all that

I find that using Animation Curve on speeds like movement makes it feel more natural if you want accelerations, or fake slowing down/friction

[kind cove]

Thanks for the tips, Ill do some more research.

Hey I needed help with a script. So I have 3 walls & a floor having "WallLayer" & i have a spherePrefab which is being instantiated on one of the walls. The spherePrefab is on PrefabLayer. Now I want to be able to drag this sphere onto any of these 4 walls. The problem I am running into is that when I attempt to click & drag this sphere another perfab is instantiated. Unity thinks I'm clicking on WallLayer when I actaully am clicking on PrefabLayer. How do I tackle this?

public class DraggableEndPoint : MonoBehaviour
{
    private bool isDragging = false;
    private Material originalMaterial;
    private Color originalColor;

    void Start()
    {
        originalMaterial = GetComponent<Renderer>().material;
        originalColor = originalMaterial.color;
    }

    void OnMouseDrag()
    {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;

        if (isDragging && Physics.Raycast(ray, out hit, Mathf.Infinity, LayerMask.GetMask("WallLayer")))
        {
            Vector3 hitPoint = hit.point;
            gameObject.transform.position = hitPoint;
        }
    }

    void OnMouseDown()
    {
        if (gameObject.layer == LayerMask.NameToLayer("EndPointLayer"))
        {
            isDragging = true;
            GetComponent<Renderer>().material.color = Color.black;
        }
    }

    void OnMouseUp()
    {
        if (gameObject.layer == LayerMask.NameToLayer("EndPointLayer"))
        {
            isDragging = false;
            GetComponent<Renderer>().material.color = originalColor;
        }
    }
}

public class LeftWallController : MonoBehaviour
{
    public GameObject lineEndPointPrefab;
    private GameObject currentSphere;

    void Update()
    {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;

        if (Input.GetMouseButtonDown(0))
        {
            if (Physics.Raycast(ray, out hit, Mathf.Infinity, LayerMask.GetMask("WallLayer")))
            {
                // Check if the hit object is on the WallLayer
                if (hit.collider.gameObject.layer == LayerMask.NameToLayer("WallLayer") && hit.collider.gameObject == gameObject)
                {
                    Vector3 hitPoint = hit.point;
                    currentSphere = Instantiate(lineEndPointPrefab, hitPoint, Quaternion.identity);
                }
            }
        }
    }
}```

I gave my camera a kinematic rigidbody, and have it moveposition towards a camera target

i use lerp to get a position closer to player + an offset. And I clean up that position by getting the closest position within level bounds to that position

i set a variable for camtarget. So CamTarget can be set to follow the transform of a player. Or for autoscroll, you set cam target to some invisible gameobject that moves

it is not cameraController’s job to find out what the target is supposed to be. That’s someone else’s job

I also split CameraTarget to CamTargetX and CamTargetY. This way you can have sidescrolling in X, while tracking the player’s Y coordinate.

[lilac crow]

i did tis but nothing Changed .
please look at this if anything is wrong tell me please.

[summer stump]

I don't see visual studio in the package manager

Which is the only thing that matters in it haha

[lilac crow]

its in bottom

[summer stump]

Not in that screenshot

[short hazel]

Visual Studio, not Visual Scripting

[summer stump]

And that is a TON of extensions

[short hazel]

Also this screenshot is incredibly cursed, like there's 3 instances of VS code and weird extensions

[lilac crow]

see i have it

it 2.0.22

[summer stump]

I think they just collaged three screenshots after scrolling

Then yeah, it all looks good.

Only three things matter. The microsoft Unity extension, that package, and the External Tools being set

[lilac crow]

well i didnt wanted to send multiple screenshots to i put them to gather

[summer stump]

Vs code just... has problems sometimes 🤷‍♂️

Try restarting your computer?

[lilac crow]

i have them all , then why its still not working?

[lilac crow]

i just turn it on again

[summer stump]

Because Unity doesn't officially support vs code and microsoft is still working of implementing their own support? No idea. Lots of people have issues with it

It all LOOKS right. It SHOULD work

[lilac crow]

so if i change to visual studio itself it might work?

[summer stump]

Visual Studio is directly supported and should work yeah. I HAVE seen people have issues with it too though

[rich adder]

wdymlag? things in reallife don't lag lol

[lilac crow]

yeah its working with visual studio!

[rich adder]

like a weapon sway ?

[lilac crow]

@summer stump thank you for your guidence!🌹🌹😘😘

[rich adder]

yeah my guy

thats called weapon sway

this dude has uhhh premade script from gpt (oh nvm it was a joke on gpt, the script is in the description) seems to work
https://www.youtube.com/watch?v=LIWA1Rgy42A

[noble sequoia]

What's your code look like

[tender stag]

does this look messy?

[short hazel]

You can use [field: SerializeField] on your property implementations there, to expose the field in the Inspector without needing to make one yourself

[field: SerializeField]
public float Durability { get; set; }

field: instructs the compiler to put the attribute on the backing field that's auto-generated for the property

[rich adder]

wait you can see values from interface in inspector?

[tender stag]

yeah i didnt know either

[rich adder]

oh nvm they mean the class under it

[short hazel]

You can't. You put the attributes on the implementing properties in the class

[rich adder]

yeah misread that xD I was about to sayy..

[tender stag]

whats wrong with this then?
