Thank you guys

[open kernel]

object reference not set to an object, why?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using TMPro;
public class buttonpress : MonoBehaviour, IInteractable
{
    public Animator buttonAnimator;
    public AudioSource source;
    public AudioClip clip;
    public TMP_Text buttoncount;
    public int counter = 0;
    public void Interact()
    {
        counter += 1;
        source.PlayOneShot(clip);
        buttoncount.text = counter.ToString();
        buttonAnimator.SetTrigger("press");
    }
    // Start is called before the first frame update
    void Start()
    {
        buttoncount = GetComponent<TextMeshProUGUI>();
    }

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

    }
}

[earnest atlas]

probably u set it to prefab?

[summer stump]

Is the button in the same object as this script?

[open kernel]

yes

[summer stump]

Show the inspector for it

[open kernel]

for the button?

[frigid sequoia]

You are changing the reference of buttoncount on start even though you have it assingned in the inspector , are you sure that is a valid reference?

[summer stump]

For the object with this script

[open kernel]

oh, ill try deleting it

[summer stump]

Is the TMP_Text below this?

[open kernel]

works now, deleted the start method

thank you 😄

[summer stump]

Ok, keep in mind that GetComponent only finds components on the SAME object as the script, and the text was not on this object

[open kernel]

aaaaaaaaaah

[frigid sequoia]

I just learnt yesterday thay I should try to not use GetComponent at all if possible so...

[frosty hound]

You're free to use it. Just cache the results when you can.

[carmine sierra]

Hi I have an issue:

I asume that the issue is that I need to use an else statement in this code, but not sure how to code it so that it freezes in it's position explicitly:

void OnMouseDrag()
{
if (weaponInstance)
{
poschange = mouseWorldPosition - originalPos;
if (poschange.magnitude <= maxLength)
{
GetMousePos();
weaponInstance.transform.position = mouseWorldPosition;
SetBands(mouseWorldPosition);
}
}
}

[summer stump]

I would not agree with this at all

[opaque fox]

Still running into issues here. The charging behavior works once and then the enemy wanders forever and can't look at the player again. The last if statement here (if Vector3.Distance(transform...) is never triggered ever and I don't know why.

[open kernel]

idk what is causing this but it looks cool

[earnest atlas]

_robotObject.SetActive(false);

will this disable the robot and its update calls?

[frigid sequoia]

Well, I was told that is just way better to reference it directly from the inspector if possible since it is easier to mantain the reference through changes in the project and it is less demanding to have a direct reference instead of go checking a List to find it

[swift crag]

You should favor serialized references when they're possible.

This doesn't mean you should literally never use GetComponent.

[carmine sierra]

how can I use else to freeze the coords

[earnest atlas]

This time I went out of my way with serializing

[frigid sequoia]

Firstposition is updated each frame to the player position, so comparing checking the distance between it and the player position is... always 0...

[frigid sequoia]

This question is too abstract and out of context for anyone to answer properly I think, could you explaining this better?

[carmine sierra]

i believe that because it just has an if statement, it will exit the if statement when the condition is no longer met, resulting in the object and bands from no longer going to the mouse, even when the accepted length is met again

[mild mortar]

@swift crag
Hey, I was looking over your replies earlier. But unfortunately i'm just being too stupid to really understand here.

Would you be able to point out to me exactly how you would change this to suit your modifications?

I just want it to smoothly decrease the health text when damaged, and also not have the issues with the health actually being something like 89.872 instead of 90 when I only deal int damage

using System;
using System.Collections;
using TMPro;
using UnityEngine;

public class HealthController : MonoBehaviour
{
    [Header("Health Parameters")]
    public float smoothDuration = 0.5f;
    [SerializeField]
    private float maxHealth = 100;
    [SerializeField]
    private float currentHealth;

    [Header("UI Parameters")]
    public TMP_Text healthText;
    public UnityEngine.UI.Image healthBar;

     [Header("Colour Properties")]
    public Color healthyColour = Color.white;
    public Color criticalColour = Color.red;

    private void Start()
    {
        currentHealth = maxHealth;
        UpdateText();
    }

    public void ReceiveDamage(float damage)
    {
        StartCoroutine(ReduceHealth(damage));
    }

    private void UpdateText()
    {
        healthText.text = currentHealth.ToString("0");
    }

    private IEnumerator ReduceHealth(float damage)
    {
        float damagePerSecond = damage / smoothDuration;
        float timeElapsed = 0;

        while (timeElapsed < smoothDuration)
        {
            currentHealth -= damagePerSecond * Time.deltaTime;
            currentHealth = Mathf.Max(0, currentHealth);
            healthBar.fillAmount = currentHealth / maxHealth / 2;
            healthBar.color = (currentHealth / maxHealth <= 0.4f) ? criticalColour : healthBar.color;
            UpdateText();

            if (currentHealth <= 0)
            {
                break;
            }

            timeElapsed += Time.deltaTime;
            yield return null;
        }
    }
}

[rare basin]

Learn single responsibility rule

[earnest atlas]

Whats that?

Much of serialize I have there are just for debug

[rare basin]

Google

[frigid sequoia]

But like, we don't know how the rest of the code is working or the setup of the game

[swift crag]

Store the displayed health percentage in a field. Use Mathf.MoveTowards to steadily move it towards your actual health percentage.

[summer stump]

Honestly, i would still disagree with that too
But it is a helpful way to do it
It's important to keep in mind that there is still work the processor does to reference the serialized fields, and it's not much less than GetComponent. The issue is surety and clarity

[earnest atlas]

Ah that, funny enough it that script mostly deals with movement

[frigid sequoia]

Probably once you have already pressed to hold the sling, it should stop checking anything else and enter a state where it just moves relative the mouse until you release it

[rare basin]

Mostly

[earnest atlas]

Yeah like 90% is movement and chasing logic

[carmine sierra]

thats what its already doing, but once it leaves the range it freezes, and even if the mouse enters the range again, it won't follow the mouse anymore

[frigid sequoia]

Pretty sure it is checking if the mouse is pressed AND in range at the same time then

You should only check if in range to do the initial press

[carmine sierra]

not sure what you mean

[earnest atlas]

How to create an interface?

Just add new script and remove all text leaving only interface?

[shell sorrel]

public interface IMyInterface { ...

then you define only function signatures in it

[earnest atlas]

I know how they work, Im not sure how does unity implements them

[shell sorrel]

like what do you mean, to implement them you just extend from it

[swift crag]

There's nothing special about interfaces and Unity.

[shell sorrel]

public class MyThing : MonoBehaviour, IMyInterface {

[swift crag]

(there's very rarely anything "special" going on in C#-land)

[shell sorrel]

doing so will force you to define all of its methods

[frigid sequoia]

If you don't show the entire code I don't think I can be of much more help, but pretty sure that you are indeed checking for two conditions in an if statement and fulfilling only one once you move out of the interaction range

[mild mortar]

Sure, so here's what I've done.

using System;
using System.Collections;
using TMPro;
using UnityEngine;

public class HealthController : MonoBehaviour
{
    [Header("Health Parameters")]
    public float smoothDuration = 0.5f;
    [SerializeField]
    private float maxHealth = 100;
    [SerializeField]
    private float currentHealth;

    [Header("UI Parameters")]
    public TMP_Text healthText;
    public UnityEngine.UI.Image healthBar;

     [Header("Colour Properties")]
    public Color healthyColour = Color.white;
    public Color criticalColour = Color.red;

    private float displayedHealth;

    private void Start()
    {
        currentHealth = maxHealth;
        displayedHealth = currentHealth;
        UpdateText();
    }

    public void ReceiveDamage(float damage)
    {
        StartCoroutine(ReduceHealth(damage));
    }

    private void UpdateText()
    {
        healthText.text = Mathf.RoundToInt(displayedHealth).ToString();
    }

    private IEnumerator ReduceHealth(float damage)
    {
        float damagePerSecond = damage / smoothDuration;
        float timeElapsed = 0;

        while (timeElapsed < smoothDuration)
        {
            currentHealth -= damagePerSecond * Time.deltaTime;
            currentHealth = Mathf.Max(0, currentHealth);
            // Smoothly updates the displayed health towards actual health
            displayedHealth = Mathf.MoveTowards(displayedHealth, currentHealth / maxHealth * 100f, smoothDuration / timeElapsed); // Calculate smoothness based on remaining time
            healthBar.fillAmount = currentHealth / maxHealth / 2;
            healthBar.color = (displayedHealth / 100f <= 0.4f) ? criticalColour : healthBar.color;
            UpdateText();

            if (currentHealth <= 0)
            {
                break;
            }

            timeElapsed += Time.deltaTime;
            yield return null;
        }
    }
}

I have a question though as it has to still be wrong, I am spamming my trigger to deal 5 damage as a test, but if I do it rapidly. It seems to mess up the health somehow, for instance, I am currently on 13 health even though it should only be taking 5 damage?

[mild mortar]

Ah my bad, sorry

[swift crag]

Do not mess with how the player actually takes damage

Don't smear out the damage over time.

You're strictly smoothing out how you display your health

[mild mortar]

Hmm, could you point out to me where I'm going wrong here then?

I'm genuinely not sure where I've messed up

[swift crag]

You're starting a whole coroutine when you take damage

Just subtract the damage from your health. That's it.

[frigid sequoia]

You said you are managing health as ints, why are you declaring the health as floats then?

[swift crag]

That's all of your logic for changing your actual health value.

Then, in Update, you can smoothly move the displayed health percentage towards your current health percentage

You can throw out ReduceHealth entirely.

It doesn't make sense to start a coroutine for every instance of damage, all of which fight over the health text

void Update() {
  float currentPercentage = currentHealth / maxHealth;
  displayedPercentage = Mathf.MoveTowards(displayedPercentage, currentPercentage, Time.deltaTime * 3f);
  healthText.text = $"{displayedPercentage:P0}";
  healthBar.fillAmount = displayedPercentage;
  healthBar.color = displayedPercentage < 0.4f ? criticalColour : normalColour;
}

that's pretty much it

[mild mortar]

Okay got it, sorry about that and thanks also.

Genuinely braindead right now lol

Haven't taken a break in hours

[swift crag]

in short: separate your actual values from your displayed values

[frigid sequoia]

If you don't you will get weird results such as taking damage that sets you to 0 health but you still have to wait for it to do the transition even though you are already dead

[swift crag]

yeah

[mild mortar]

Yeah, think that was the kind of thing I noticed earlier too

[swift crag]

For bonus points, extract this logic into a Healthbar component

It can keep track of its smoothed out values on its own

[opaque fox]

transform.position should be the AI's position though

i'll do agent.transform.position tho and see if that helps

nope, still doesn't trigger the block

[frigid sequoia]

Add a Debug.Log to tell you the two positions you are checking and the distance between them, that usually helps a lot to spot this kind of issues

[opaque fox]

Not sure what to make of this. It charges directly towards the first known position of the player once the timer hits the certain point, but then it goes back to wandering

[turbid robin]

what is this? is in the ar project template

[opaque fox]

Doesn't seem to be... actively calculating the distance maybe?

[mild mortar]

Regarding this, I just had one more question

public void ReceiveDamage(float damage)
    {
        currentHealth -= damage;
    }

    private void Update() 
    {
        displayedHealth = Mathf.MoveTowards(displayedHealth, currentHealth, Time.deltaTime * 5);
        healthText.text = displayedHealth.ToString("0");
        healthBar.fillAmount = displayedHealth / maxHealth / 2;
        healthBar.color = displayedHealth < 0.4f ? criticalColour : healthyColour;
    }

Is it not inefficient to be running this update every frame even though the health will only change on damage or healing?

I was wondering if there's a more optimal way to do this so that it is still smooth but not wasting any resource?

[frigid sequoia]

The distance should definetly be a float, those are positions

Do Debug.Log ( "Position: " + transform position + " // Target Position: " + firstPos + " // Distance: " + Vector3.Distance (transform.position, fistPos))

[storm imp]

what does this mean?

[dense cypress]

how can I square a vector

[polar acorn]

What does what mean

[dense cypress]

or, more specifically, make it exponentially smaller

[storm imp]

the reference

[polar acorn]

What about it

[low path]

what do you mean square it/make it exponentially smaller?

[storm imp]

why is it there?

[polar acorn]

...because that's where you're using this function?

[storm imp]

ok

[dense cypress]

get a vector (for move direction/speed) and if it goes above a certain threshold: decrease it (and decrease it more if it's a higher number)

[storm imp]

then that has nothing to do with my problem : (

[polar acorn]

You haven't mentioned a problem

[storm imp]

I can't seem to be able to click the button I made to go to the next site

[oak mist]

Yo again, I’ve got a new asset for a turret I’m working on, it’s the sci-fi turrets (cannon) asset from unity asset store, and I want to have the user use the left and right controls to move the turret left and right (this is a placeholder, I am supposed to use a robot to move it later on, but I know how to make the change). I’ve done something similar with a very basic turret I made using cubes, the code for that is here: https://pastebin.com/6qezXDh5. I want to convert this code into now be able to change the x axis of the turret (its split into 2, the base and the gun). Are there any videos, or any steps where I can learn that.

[polar acorn]

Show button

[verbal dome]

Probably just some preview image for the template package

[storm imp]

actually it's an icon

[polar acorn]

Okay how are you actually handling clicking on this object

[low path]

so you have value v. threshold t1, threshold t2 above t1. clamp v to t2 at the top. take diff = abs(v - t2). then damping = diff / (t2-t1). multiply damping by v. you could also square damping for a faster dropoff. math might be slightly off but the basic idea is you are applying a damping factor between 0 and 1 based on where your value is above your threshold, up to a full dropoff threshold (t2).

[frigid sequoia]

Maybe what you want to do is to Clamp each of the axis of the vector????

[steady isle]

I have figured out mainly all of the basics of c# and i want to start coding with unity 3d, but i dont know where to start with all of the new code

[rich adder]

check the pins in this channel

plenty of resources to learn

[low path]

just start making a simple project and look up all the things you need to do

[rich adder]

bad way to learn..

[low path]

??? nah

how else would you learn?

[raven hill]

using System.Collections;
using System.Collections.Generic;

Does anyone know why the Debug.Log doesn't write anything?

[rich adder]

following a structured course

instead of running around like headless chicken

[low path]

that's one way but learning by doing is also a completely valid way

[storm imp]

here's the code
https://gdl.space/ufekecodoh.cs

[rich adder]

you can't do anything if you don't know the basics..

like proper syntax

[low path]

they said they figured out hte basics of c#

[mortal bridge]

@mild mortarhey man you fixed it? I wrote 120 lines of codes myself in the moment (with 13 errors left to fix now)

[rich adder]

people say a lot of things, doesn't mean its true

[rich adder]

is there a question here ?

[low path]

ok well... i've been doing this for a long time and looking up every item i want to do is how i learn

[mild mortar]

Hey bud, yeah it's fixed now. I managed to use someone else's suggestion 🙂

Thanks for everything

[raven hill]

Does anyone know why the Debug.Log doesn't write anything?

It was under the code

[mortal bridge]

can you reference the solution

everyone can learn

[swift crag]

It's completely fine.

[rich adder]

your condition is never true

[polar acorn]

Log hit.transform.gameObject inside your raycast, but outside any of those if statements. See if it ever hits anything at all

[raven hill]

But shouldn't it be true after 0,5 seconds after throwing AND in the beggining?

[rich adder]

if the log is not writing
A. either script is not running
b. you have compile errors (see #1)
c. Your if statements aren't evaluating to true

[brazen canyon]

Hey man, my Player object has the scale of 1,2,1
What do i have to do ?
I can't ruin the scale
It was originally a sphere
Can I make turn the sphere into a capsule ?

[amber veldt]

Hey guys, can you call a OnCollisionEnter function on an empty parent object?

[raven hill]

not the first 2

[swift crag]

That's why I suggested parenting the visual object to the player object

the Visual can be scaled however you want

[rich adder]

okay so either canThrow = false
or the other one
!(distanceX<=WantedDistance

[swift crag]

the Player should have a scale of [1, 1, 1]

[mortal bridge]

yeah your right

"maybe" set it to change in update once its changed?

[raven hill]

yh

I see it now

thx

[brazen canyon]

What's Visual ? (in this context)

[polar acorn]

the thing you see

[swift crag]

#💻┃code-beginner message

[mild mortar]

How do you mean? I've been trying to find out a way to solve it similar to what you said, but I haven't been sure

[swift crag]

There is nothing to solve. Just update the text and healthbar every frame.

It's fine

[mortal bridge]

maybe my man has a thing with optimizations

[mortal bridge]

h1mmm

[brazen canyon]

Is Sphere the Visual here ?

[verbal dome]

Experimentation is good, but it's way less frustrating when you know the basics
And, well, way more efficient

[swift crag]

Correct. You shouldn't have anything else parented to it.

[polar acorn]

Is that the thing you see

[swift crag]

Compare your hierarchy to the one I showed you.

[mild mortar]

No worries, I'll keep it more or less as it is then, thanks for you help 🙂

All I've done for now is just put it inside an if statement checking if the health matches

[mortal bridge]

hmmm so

you could do property? or coroutine? even delegate?

[swift crag]

those are various concepts, yes

i'm not sure why you're bringing any of them up

[mortal bridge]

to be able to update health only when it changes

[swift crag]

Add a component that responds to OnTriggerEnter

Have it call a method on something else.

[low path]

i'm not saying blindly experiment, i'm saying have some simple project you'd like to make and each time you need to know how to do something to make that project, look up what you need to do.

[swift crag]

public class Hitbox : MonoBehaviour {
  [SerializeField] Player player;

  void OnTriggerEnter() {
    player.Hurt();
  }
}

[amber veldt]

So I can't avoid the script on the children?

[swift crag]

e.g.

[dense cypress]

how can I restrict the force that a rigidbody has? (Stop player from going 2786 mph from holding w)

[amber veldt]

Or maybe serialize the child?

[swift crag]

If a parent has a Rigidbody on it, then components that are siblings to the Rigidbody can receive trigger and collision messages.

[timber tide]

clamp your velocity

[wintry quarry]

Rigidbodies don't "have" force, they have velocity

[dense cypress]

how do I restrict the velocity then

[amber veldt]

If a child has a RB/Collider, I can't call it on a parent object, right?

[wintry quarry]

Either clamp it directly or don't add force or add reduced force when going too fast

another option is add drag forces

or use the Rigidbody drag feature built in

[mortal bridge]

maybe he means addforce and got confused

I know this man he is total beginner

[wintry quarry]

Yes I know what he meant just clarifying a misconception to make his understanding more clear

[swift crag]

"rigidbody" and "collider" are two extremely different things

[dense cypress]

I take mild offence to this

[amber veldt]

Yes I meant "rigidbody + collider"

Since you need both

[swift crag]

A rigidbody allows an object to be affected by physics. It uses all of the colliders that are parented to the object.

[mortal bridge]

Im sorry didnt mean that. maybe people could help you better if they know this

[swift crag]

Trigger or collision messages involving the child collider will also go to the rigidbody's object

Although, I am not sure off the top of my head if a receiver on the child will "eat" the message

i.e.

[dense cypress]

I mean I started doing unity and c# like a week ago so I'm pretty proud with how well I'm doing

[swift crag]

• Root <- rigidbody, trigger-listener
  • Child <- collider, trigger-listener

I'm not sure if Root will get OnTriggerEnter messages

[swift crag]

anyway, this is the most general way to do it.

[mortal bridge]

very good man

[swift crag]

It's also very useful.

[dense cypress]

damn I just added 1 drag and the problem is solved

[swift crag]

You can add information that's specific to that collider (imagine a head hitbox that causes more damage)

[amber veldt]

Root <- script
Child <- collider, rigidbody

This is what I have, I want to trigger "OnCollisionEnter" on the root script

To centralize stuff you know

[swift crag]

Why is there a rigidbody on the child?

[amber veldt]

Is this bad practice?

[verbal dome]

I think only the root will get the messages here

[swift crag]

well, if Rigidbody is non-kinematic, it'll fall away from the Root

[amber veldt]

oooooh that's why

[swift crag]

I just don't see why you aren't putting the rigidbody on the root

[amber veldt]

God dammit that makes so much sense

I'm an idiot

[swift crag]

The rigidbody defines what the object "is"

[amber veldt]

Ok and for the "rendering", I leave it on the child right?

[swift crag]

You generally want to parent the visuals to something else, yeah.

[dense cypress]

how can I allow player to walk up a hill/steps without a character controller because I have a rigidbody and last time I checked they don't work well together

[amber veldt]

Like Root > Collider/Rigidbody/Script
Child > Renderer?

[swift crag]

The collider can also be on a child.

[amber veldt]

Ok

[swift crag]

But you can leave it on the parent if you don't have a strong reason to put it somewhere else

[amber veldt]

For the headshot/Torso shot... etc?

[swift crag]

Definitely for these. You'd attach the colliders to various bones on your armature.

[amber veldt]

Ok man, thank you, you're amazing

[random totem]

is there any way to make a line renderer keep rendering? when every my camera gets too far from the center of my line, it stops rendering even if some of the line should still be visible (like this)

[swift crag]

Looks like the answer is "both"

[verbal dome]

Maybe your camera's far clipping plane is too low

[swift crag]

god this test project is a mess

[mortal bridge]

characterController?

[wintry quarry]

Make sure your Renderer's Bounds are correct https://docs.unity3d.com/ScriptReference/Renderer-bounds.html

[dense cypress]

the built in component

[swift crag]

You'll need to look for stairs and pull yourself up them yourself, then

that's why people like to use the CharacterController (:

[mortal bridge]

why not use it?

[swift crag]

You'd raycast downwards, starting from a little in front of your character, and see if the ground isn't much higher than the player

if so, raise yourself up onto it

[storm imp]

he doesn't have this in the tutorial but when I remove it I get about 30 errors

[verbal dome]

Oh, interesting. I remember wrong then

[dense cypress]

how does one raycast

[swift crag]

https://docs.unity3d.com/ScriptReference/Physics.Raycast.html

[mortal bridge]

characterController has built in var for that kind of movement. why not use it?

[summer stump]

It kinda handles things poorly in many cases.
It can be perfectly fine to use though

[mortal bridge]

so does raycast

[frigid sequoia]

If I have all my enemy prefabs searching for the player on Start, would it be better to have a general script just to store a reference to the player to reference it directly from there instead of searching it anew every time or it doesn't really matter?

[summer stump]

False
Plus the cc USES raycasts

[turbid robin]

i have this button with the code:

using UnityEngine;
using UnityEngine.SceneManagement;
 
public class Button : MonoBehaviour
{
    public void NextScene()
    {
        SceneManager.LoadScene("SampleScene");
    }
}```
when i try to click on it it dosent take me anywere. any suggestion?

[wintry quarry]

It's probably better to just directly pass the reference to the enemy script as you spawn it, from the spawner script.

Rather than "finding" it

[polar acorn]

Why do you have a random block section with no condition or loop before it

[slender nymph]

give whatever spawns the prefabs a reference to the player and it can just pass the reference to the prefabs on spawn

[wintry quarry]

Does the code actually run? Did you put a log in to make sure it runs? Are there errors?

[polar acorn]

You have to actually set the function you want it to call

[turbid robin]

yes, the code runs, not i didn put a log in, there are no errors

[storm imp]

🤷‍♂️

[languid spire]

you added the button script not a gameobject which has the button sript

[turbid robin]

can you explain more?

[mortal bridge]

I mean when you walk down the hill

[wintry quarry]

How d you know the code runs if you didn't put a log in?

[frigid sequoia]

The thing is, I was planning the spawner to be a separate prefab object instead of a general manager that stays in scene

[mortal bridge]

there has to be something there

[wintry quarry]

There's No Function assigne dhere

[rich adder]

did you actually link the function

[wintry quarry]

the code is definitely NOT running

[turbid robin]

i start the run time?

[wintry quarry]

so>?

[summer stump]

What about it?
Raycast is perfect for that

[slender nymph]

something is gonna have to put it into the scene though and that can just pass the player reference along

[turbid robin]

isnt that the code starting?

[wintry quarry]

No

[polar acorn]

Okay, are you calling this function in Start somewhere then?

[mortal bridge]

so you'd have to forcefuly apply - gravity

[wintry quarry]

This is how you set up your button to run the code, and you haven't done it properly

See how it says "No Function"

[rich adder]

No Function

literally

[summer stump]

As you do with cc
But you DON'T have to do with raycast and dynamic rigidbodu

[verbal dome]

I prefer SphereCast over Raycast when doing grounded/movement sensor checks. A ray can go through a tiny gap which is usually unwanted

[turbid robin]

oh yeah i saw that

but i dont see anything useful there

[wintry quarry]

because as someone already mentioned, you dragged the wrong thing in

you dragged the script in

that's not correct

[rich adder]

u need to drag the script from the object
not from the project folder

[languid spire]

script instead of gameobject with script

[mortal bridge]

step offset?

[slender nymph]

https://unity.huh.how/unity-events/incorrect-assignment

[turbid robin]

oh ok, so i add the script to my button, and then drag it as function

[storm imp]

what do I do?

[verbal dome]

I must've assumed/misremembered that it works like OnCollisionEnter, which gets sent to the rigidbody only. Which I don't see mentioned in the docs anywhere 🤔

[rich adder]

sure, but I would advise against putting scripts nested in UI objects. But ofc do whatever is easier rn

[polar acorn]

About what

[summer stump]

It's quite clear you don't really understand, and that is fine. But raycast is not the alternative for character controller
Rigidbody or transform movement is.
CC USES raycasts to do what you're talking about

[wintry quarry]

no you drag the GameObject that has the script attached to it into the button slot

it doesn't have to be the same object the button is on

but it could be

[turbid robin]

somethng like this?

[low solstice]

why is Length returning high values? (correct value + 1)

using UnityEngine;
using TMPro;

public class MenuUIHandler : MonoBehaviour
{
    private TMP_Text playerNameText;

    void Start()
    {
        // text GO within text area GO, not the placeholder
        playerNameText = GameObject.Find("PlayerNameText").GetComponent<TMP_Text>();
    }

    void Update()
    {
        if (playerNameText.text.Length > 0)
        {
            Debug.Log("\"" + playerNameText.text + "\" = " + playerNameText.text.Length);
            // always greater by 1 than it should be?
            // "" = 1
            // "t" = 2
            // "test" = 5
        }
    }
}

[storm imp]

my problem

[rich adder]

naming your script Button is a bad idea

[wintry quarry]

Yes - though the fact that you named your script Button is causing that annoying naming conflict you see

[verbal dome]

This might be that invisible character problem

[polar acorn]

What is your problem? I don't know what this question had to do with you adding in a debug log to check your raycast which you haven't done yet

[polar acorn]

If that TMP_Text is the placeholder text for a UI Input, there's an invisible character at the end

[turbid robin]

oh ok, but now what do i need to put as function?

[rich adder]

try to avoid the names unity already took, until you start learning namespaces

[polar acorn]

The function you want to call

[verbal dome]

@polar acorn Was it you who was familiar with this? Invisible character at the end of TMP_Text.text

[storm imp]

What do I add?

[turbid robin]

next scene?

[rich adder]

isnt that what you want to run lol

[polar acorn]

Yes, I'm checking my post history to find that character code

[polar acorn]

#💻┃code-beginner message

[mortal bridge]

well thanks. I intentionally finished the sentence with ? for a reason

[storm imp]

you think I know what that means

[frigid sequoia]

It was meant to be a bunch of prefab levels where the spawners are preset on a possition and whatever they spawn of if they spawn anything at all to be somewhat randomized

[polar acorn]

Found it. This problem drove me up the wall a month or two ago and this is how I solved it
#💻┃code-beginner message

[turbid robin]

thx for all the help, the code is working and i am starting to learn more

[swift crag]

Indeed!

I also couldn't get OnCollisionEnter to work at all, which is...weird. But OnCollisionStay indeed fired only on the parent.

[frigid sequoia]

And not have a proper SpawnManager for the task

[polar acorn]

Yes. Debug Log should literally have been the first line of Unity code you ever wrote, and I told you exactly where to put it and what to log

[slender nymph]

okay? so why does that prevent you from passing the player reference when the objects are spawned?

[turbid robin]

now i try to build the app and pray that everything works

[summer stump]

I assumed that reason was that you thought I was unaware of step offset. A meaningless half-sentence with a questionmark is usually sarcasm. Sorry for that assumption

[mortal bridge]

no problem my bad. I need to communicate better via text

[low solstice]

wow, okay. thanks to you and @verbal dome for suggesting invis chars

[storm imp]

I guess I 've got to learn to write Debug Log

[frigid sequoia]

That I don't have it stored anywhere to pass it

[mortal bridge]

I never do sarcasm when its about learning.

[polar acorn]

You should not have gotten this far without doing so in the first place

[slender nymph]

man if only you could change your own code to be able to do that

[storm imp]

ok I'll go do that now

[verbal dome]

OnEnter not working does sound unusual, especially if OnStay worked 🤔

[wintry quarry]

Lesson 1:

• Use Debug.Log when you don't know what's going on. You made an assumption your code was running. Debug.Log would have proved that assumption false for you and gotten you looking into why it wasn't running.

[turbid robin]

on the unity engine i see the button in the scene, but on the build and the phone i dont see it. i thinl its because i need to set the scene to be the first, but how do i do that?

[turbid robin]

i will learn how to use it

[slender nymph]

you can change the scene order in the build settings. but i'm willing to bet that the issue is your canvas scaling

[turbid robin]

i dont think the problem is canvas scaling

[rich adder]

but what about canvas scaler

[wintry quarry]

that doesn't really tell us anything about canvas scaling

[slender nymph]

that screenshot proves nothing

[turbid robin]

oh no it was because i didnt put the scene

[frigid sequoia]

That was... what I was asking... if I should change it to have a reference of the player stored on a abstract script accesible for everyone instead of searching for it for each object

[rich adder]

well might want to check scaler as well, make sure its set to scale with Screen

[turbid robin]

but now i have the sample scene (the ar one) set as 0, ant the menù set at 1. i need to change the order

[rich adder]

You can easily drag them around to change order

[slender nymph]

and this entire time i've been telling you to store the reference to the player on the object that spawns those other objects so that the reference can be passed to them when they spawn instead of relying on any Find calls or whatever it was you were doing before

[turbid robin]

thx

now lets test if scaling was right and if boxfriend won the bet

[rich adder]

Your canvas scaler is probably still wrong, button Might appear but could be wayyy off then it is in scene view

proper anchoring and canvas scaler set to Screen is a must

[turbid robin]

lets repair this problem, what do i need to check?

[queen adder]

is instantiate real?

[rich adder]

Canvas Scaler component on the Canvas

[queen adder]

unity is telling me its not

[mortal bridge]

damn thef the hell is wrong with the fing animator? Everythings saved except for the changes I made in animator Im really sick of it. I set run static as layer default state now its idle again and also the animations are just fkin messed up

[rich adder]

yup its wrong
you need Scale With Screen and set a base resolution

Constant Pixel Size isn't good option

[polar acorn]

No

Instantiate is though

[turbid robin]

scale it with screen size? is it better?

[mortal bridge]

Im really sick of unitys animator

[rich adder]

use Animancer then

[queen adder]

thank you

I wonder if Animancer uses AnimationClip.SampleAnimation under the hood

[mortal bridge]

I thought conditions resetting was the only issue so i switched to latest again im so stupid

never used an external one gotta check out

[queen adder]

thank you, very annoying knowing everything is broken cause i suck at spelling

[rich adder]

were you the one who had the Transition conditions Unset itself ?

[mortal bridge]

yes

do we have to manually save the animator exceptionally itself or something?? is saving the project not fkin enough???

[verbal dome]

Have you tried creating a new animator controller?

[rich adder]

and you tried multiple unity version ?

I never seen this issue b4

[verbal dome]

Just in case the file itself is somehow messed up

Yeah, it should save without any extra hassle

[frigid sequoia]

But the objects that spawns the enemies are separate several objects, storing a reference there doesn't fix anything

[mortal bridge]

that may be the case or my HDD is finally dead or something

[slender nymph]

it eliminates the need for any of the costly Find methods

[queen adder]

on line 103 and 123 it says "cannot convert type 'UnityEngine.Transform' to 'UnityEngine.GameObject' "
https://hastebin.com/share/joyezafoxo.csharp

[swift crag]

okay, so give all of them a reference to the player

[mortal bridge]

It feels so bad when you made a lot of progression just to see it mess it up itself

[wintry quarry]

Yeah because you wrote:
foreach (GameObject slot in slotList)
but slotList is a List<Transform> not a List<GameObject>

[rich adder]

exactly

computer never is wrong

[polar acorn]

slotList is a list of transforms. You're trying to store one element of it in a variable of type GameObject

These are not the same class

[dense cypress]

trying this if (Physics.Raycast((transform.position + new Vector3(0, 0, 1), transform.TransformDirection(Vector3.down), 1))) but it's saying to make a struct and add in like 80 lines at the bottom and I'm not sure that's what I want

[swift crag]

what's saying to "make a struct"?

[dense cypress]

it's an error

for the potential fixes

[slender nymph]

oh they've gone and thrown a tuple into the parameters for Raycast

[swift crag]

You've made a weird tuple

(1, 2, 3) is a 3-tuple

[dense cypress]

what's a tuple

[swift crag]

too many parentheses

it's a fixed-length array, basically

[rich adder]

a type
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/value-tuples

[swift crag]

I would suggest not cramming everything into one line

create a Ray out of the position and direction

[frigid sequoia]

Once again, the spawner would still need to Find the player; is no difference having 10 spawners looking for 10 references than having 10 enemies looking for 10 references, in fact is even worse

[swift crag]

no, the spawner is given a reference to the player: either by assigning it in the inspector, or by being given to it by whoever instantiates the spawner

[slender nymph]

why would it need to find the player. something has to be in the scene to spawn things in, right? so just give that thing a reference to the player and let it pass the reference to the things that it spawns

[rich adder]

https://unity.huh.how/references/simple-dependency-injection

[mortal bridge]

if (Input.GetKeyDown(KeyCode.Space) playerIsOnGround)
{
playerAnimation.SetTrigger("Jump_trig");
}

shouldnt this work or am I losing my mind for real. player is just in his idle state

[frigid sequoia]

The player is not prefab, it is not spawned, it is just there

[slender nymph]

exactly

[swift crag]

okay, great, so you can just assign a reference to the player

[slender nymph]

so just give the spawners the reference

[rich adder]

wrong syntax

this wouldnt even compile

[swift crag]

you can multi-select all of your spawners and give them all the reference at once

[frigid sequoia]

Is a thing on the scene, and I cannot give a reference to object on scene to a prefab

[rich adder]

!ide @mortal bridge

[swift crag]

okay, then whoever creates the spawners is given a reference

[mortal bridge]

I mean there is && but I tried to delete it but forgot the onground part

to make it a simpler code

[slender nymph]

what is in the scene that spawns those other prefabs? because, like i've been saying this whole time, you give that object the player reference

[rich adder]

why are you sending omitted code then
that makes 0 sesnse

[verbal dome]

So it's in the idle state? This transition goes from Walk, not from Idle

[mortal bridge]

if (Input.GetKeyDown(KeyCode.Space) && playerIsOnGround)
{
playerAnimation.SetTrigger("Jump_trig");
}

here you go

this is copy paste

[rich adder]

better

[mortal bridge]

It "starts" as idle

doesnt change at all

[rich adder]

is it going into walk first though

[mortal bridge]

yeah theres that. but it doesnt go into jump animation

when jumping its idle

[frigid sequoia]

I guess I could store a reference there, you are right

[rich adder]

then make a transition from Idle to jump?

[frigid sequoia]

It isn't not yet implemented so I was not thinking about it sry

[mortal bridge]

why would I. characters supposed to jump while running that would look unnatural

[rich adder]

You're the one who says it doesnt go into jumping if its Idle. So I'm confused on your original issue lol

[sharp wyvern]

if (Input.GetKeyDown(KeyCode.Space) && playerIsOnGround)
    {
        Debug.Log("Jumping");
        playerAnimation.SetTrigger("Jump_trig");
    }``` confirmed this stuff is actually running yet @mortal bridge?

[mortal bridge]

It does. there is no jumping "animation"

[verbal dome]

So does it change or does it go to walk. Pick one

[dense cypress]

Vector3 rayStart = transform.position + new Vector3(0, 0, 1);

//raycast direction
Vector3 rayDir = transform.TransformDirection(Vector3.down);

//actual raycast
if (Physics.Raycast(rayStart, rayDir, 1)) ;
{
    transform.position = transform.position + Vector3.up;
}```

(this might be too long and need to go into website but I can't really be bothered)

would this work?

[mortal bridge]

Game starts check
player walk animation for 0.5 seconds check
idle forevermore check

[swift crag]

you should be using the actual point that you hit

[mortal bridge]

it does

theres just no animation

[swift crag]

Also, you put a ; after the if statement, so it's not actually controlling the following block

[dense cypress]

how do i get that

[swift crag]

if (Physics.Raycast(start, dir, out var hit, 1f))
{ ... }

as described on the doc page

[sharp wyvern]

good catch!

[swift crag]

the third parameter is out RaycastHit hit

an out parameter lets a method assign something into a variable

You can declare a variable as you pass it into the method.

[swift crag]

and var can be used in place of RaycastHit, hence why that works

..., out RaycastHit hit, ...

this would also work

[mortal bridge]

everything you can ask for

sorry for the great wall of china.

Im just so sick of this animation stuff

[rich adder]

could've just madea thread..

[mortal bridge]

want it sorted out

[rich adder]

also #🏃┃animation

[mortal bridge]

Its actually somehow related to code

[rich adder]

how so you said the trigger ran ?

[mortal bridge]

SetTriggerSetBoolSetInteger

these 3 is all I have

for animation stuff

oh i missed the so there i thought you asked how it ran

so yeah it runs

no animations

[rich adder]

so then its not the code lol

[mortal bridge]

okay I move there then

let me break down the great wall of china

[rich adder]

make a video of the Animator during playmode with object selected, it will show whats happening with transitions

[dense cypress]

I'm rather confused but why does this if (Physics.Raycast(rayStart, rayDir, out stepLocation hit, 1)) have an error (chances are it's because I didn't understand your code due to lack of experience)

[polar acorn]

what error

[quartz mural]

plzzzz help

[rich adder]

with ?

[swift crag]

stepLocation is not a valid type

consider RaycastHit, which is the correct type

[rich adder]

I dont understand video

[swift crag]

rather than the wrong type

[wintry quarry]

Your object doesn't have a Text on it, it has a TMP_Text. Use the correct type in your code.

[quartz mural]

i cant move diolog text in doiolog box

[quartz mural]

ill show u the code

[rich adder]

then its a TextMeshPro and you have Text

[wintry quarry]

I don'tneed to see it

[dense cypress]

right, I thought I was putting in a variable

[random totem]

it still stops rendering

[wintry quarry]

I can already see that you used Text instead of the correct TMP_Text

[swift crag]

that's hit

[rich adder]

jesus

[swift crag]

out TypeName variableName

[wintry quarry]

We don't need this

[brazen canyon]

Hey man, I have some scripts attached to a game object, it's a sphere
But now I want to duplicate this GO and make it an empty GO
Is that possible ?

[rich adder]

mate we pointed out issue already lol

[wintry quarry]

#💻┃code-beginner message @quartz mural

[dense cypress]

yep, I understand now

[quartz mural]

oh mb

[rich adder]

well yeah its possible

why not just create a new gameobject then if its gonna be blank

[earnest atlas]

How should I pass variables between scipts on the same object?

Make them public or get; private set?

[mortal bridge]

where?

I did what you said

[rich adder]

post it in #🏃┃animation

[mortal bridge]

no no where does it show it

[rich adder]

if you slect the object with the Animator during Playmode it shows you the Animator working

then you can inspect the transition

and see whats actually happenign

[quartz mural]

sorry im a begginer, if i dont use .test then what do i do 😅

[summer stump]

Also, in the future either do an actual screenshot or share code as text

[rich adder]

.test ?

[quartz mural]

ok

[wintry quarry]

What?

Already told you the answer, and it has nothing to do with ".test" or ".text"

[summer stump]

TMP_Text

[dense cypress]

now how can I turn that into a vector3 to move player there

[quartz mural]

thank u

[mortal bridge]

In Animator window?

[swift crag]

https://docs.unity3d.com/ScriptReference/RaycastHit.html

read the documentation for the type you're using

[rich adder]

well yeah...

[mortal bridge]

but when I pause and play game again view is set to the scene again

I cant track it due to it

[brazen canyon]

But the components you know ?
There're a lot of them attached to the old object.
It might be confusing ...

[rich adder]

you made it worse lol

[wintry quarry]

What are you doing

listen to what is being said

[verbal dome]

Not sure then. Praetor did mention the bounds of the renderer, but I'm not sure if you can edit the bounds of a LineRenderer

[rich adder]

Text is the old type you have to change to TMP_Text

[wintry quarry]

You can edit the bounds of any Renderer @random totem

through the .bounds property

[mortal bridge]

are those lines supposed to turn blue?

[polar acorn]

#💻┃code-beginner message

[rich adder]

blue?

[quartz mural]

how do i do that

[wintry quarry]

With your keyboard

change Text to TMP_Text

[polar acorn]

By changing the type from the one it is not to the one that it is

[mortal bridge]

well I actually dont know how to track it and nothing changes in the animator windows to be honest I checked everywhere

[quartz mural]

like this?

[rich adder]

You select the object with the animator at runtime, not diffcult

[rich adder]

not at all

not even close

[quartz mural]

😭

[mortal bridge]

It is selected but nothing changes here

[quartz mural]

ohhhh

[rich adder]

pay attention to what was said earlier

[quartz mural]

i thnk i got it

[verbal dome]

This is the type.

C# basics courses wouldn't hurt you

[mortal bridge]

Im in play mode here

[rich adder]

did you select the player or whatever has this animator?
also why the hell is it semi-transparent

[quartz mural]

yesss

i got it

thank u very much

[mortal bridge]

yes yes. I even had special moments with the gizmo to make sure

[summer stump]

The thing you changed is called the "Type"
So now in the future if someone says to change the type, you know what they meant

[mortal bridge]

damn actually nevermind. I think animation is not my field

[verbal dome]

Yeah something fishy here

[mortal bridge]

I will make someone else take care of animation stuff

Im so sick of this already

[verbal dome]

Make sure to let them know that it might be bugged

[rich adder]

I just never seen it semi-transparent

[verbal dome]

Try one thing. Reset your layout. Might be an Unity UI bug 🤔

Because yeah those are definitely supposed to not be transparent

[polar acorn]

Does your animator have layers

[verbal dome]

Good question

[dull arch]

my animation has a blue rectangle is there a way to get rid of it

[verbal dome]

I fail to see a blue rectangle here

[dull arch]

original sprites

[verbal dome]

Ah, slightly blue tinted red

[mortal bridge]

nothing changed

[wintry quarry]

Try disabling compression

[verbal dome]

Try turning off the compression or using higher quality

[mortal bridge]

why are those not suppoesd to be transparent?

[dull arch]

how do i turn off compression

[wintry quarry]

on the import settings for the image

[dull arch]

ok

[mortal bridge]

I just wanan relax myself by thinking that its not my fault but unitys fault

[dull arch]

fixed thanks dudes

[polar acorn]

So, the layers could absolutely explain why the animations aren't working properly, depending on your settings for them. I don't really do anything involved enough with the animators to ever need more than one, and I don't know what the "M" means. This might be a question for #🏃┃animation

[mortal bridge]

avatar mask

[verbal dome]

Oh, M means that it's using an AvatarMask

Maybe it has a mask with nothing selected

But yeah, more suitable for the animation channel

[mortal bridge]

can you come there?

[verbal dome]

Well I can take a look, but i'm no animation expert either

[polar acorn]

As I said I dunno animation I just know enough to know that when layers get involved everything I know is off the table

[verbal dome]

And there might be cases when a layer doesn't update at all if layers after it completely override it

Anyway moving to anim channel

[dense cypress]

how can I refer to forwards relative to the player

[verbal dome]

Sorry to be this guy, but you really should google simple questions like this

"unity get forward direction of object" would be a good search

[rare basin]

[wintry quarry]

player.forward assuming player is the player's Transform

[queen adder]

hi, is there anyone to help me please ? I don't know how to open a file .unitypackage

[queen adder]

thanks a lot

[tribal pendant]

i'm trying to instance a prefab but for some reason it's invisible? 8it's in italian if you ned i can provid translation)

[wintry quarry]

Well you never selected one in the video so we couldn't see it.

But presumably it's just not in view of the camera

most likely a Z axis position problem

You also really need to watch out for that because you're using Vector3.Distance which is also going to include the z axis distance

[tribal pendant]

so just
mousePosPrima.z = 0;
mousePosDopo.z = 0;

in update out of the if

[wintry quarry]

mousePosOra.z = 0; after ScreenToWorldPoint is probably all you need

[tribal pendant]

ok it works thanks <3

[tribal pendant]

you're basically doing this whola game for me hahah

[dusty silo]

I have a List of Edges and have a function that takes a List of Vertecies. Is there a lambda I can use to convert the List<Edge> into a List<Vertex>? or do I need to make a separate function for that?

[trim gulch]

Hi! I'm trying to make a Play again button for my game. I am using SceneManager.LoadScene(SceneManager.GetActiveScene().name);
to load the scene again, and it seems to work, but on the restart things start to behave differently and it throws this error MissingReferenceException: The object of type 'InGameUIManager' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object.

[polar acorn]

Do you have DontDestroyOnLoad objects

[trim gulch]

I don't think so

What's the default for that?

[polar acorn]

Show a screenshot of your scene before and after restarting

[trim gulch]

Oooh

[polar acorn]

You have a DDOL object that references something in the scene

When the scene reloads that object no longer exists

[trim gulch]

How do I create it for the scene again?

[polar acorn]

Create what

[trim gulch]

The DDOL Object

Or like

What can I do about it?

[polar acorn]

If your DDOL references something in the scene, either that thing also needs to be DDOL or the thing referencing it should no longer be one

Or, you could re-acquire the reference in code using a scene loaded callback:

trying to recreate character controller step-going-up and this script makes me fall through the floor, not sure why. ``` //trying to make steps work

    //raycast start

    Vector3 playerFeet = transform.position += new Vector3 (0,-1,0);

    Vector3 rayStart = playerFeet += (transform.forward * 0.5f);

    //raycast direction
    Vector3 rayDir = transform.TransformDirection(new Vector3(0,-0.75f,0));

    //actual raycast
    if (Physics.Raycast(rayStart, rayDir, out RaycastHit stepLocation, 0.99f))
    {
        //make bottom of player teleport to point
        Vector3 stepLocation2 = stepLocation.point + new Vector3(0, 1, 0);


        transform.position = stepLocation2;
    }```

[trim gulch]

Okok

[eternal needle]

If you're falling through the floor, you likely are being teleported into the floor. Your raycast which is starting inside the floor, will not detect the floor. Thus you fall

[trim gulch]

Apparently it's something with the "Rendering.DebugUpdater", I'll look into it

Thank you!

[unreal imp]

my dear freinds

is there any form to add a motion to a object which has been hit by a bullet raycast?

like motion to the direction of the ray

[dense cypress]

I'm no professional but could you have the raycast go a bit further then calculate the vector between the hit object and where the end of the raycast is? can't guarantee it will work at all but it's an idea

[eternal needle]

What part do you struggle with specifically? You can pass a value to some knockback method for what direction the bullet was going

[dense cypress]

that's probably better

[unreal imp]

            {
                if (hit.collider.attachedRigidbody)
                {
                    hit.collider.attachedRigidbody.AddForce(ray.direction * 0.1f);
                }```

[median ruin]

is there a way to add a field in the inspector where you choose a component that is a script and choose a function from that script? What I mean is, can I make my field function specific?

[low path]

well UnityEvents let you do this, and inspectors are fully customizable... what are you trying to do?

[median ruin]

I want to make a lever that can interact with scripts

[wintry quarry]

public UnityEvent onLeverPull;```

then to call it:

onLevelPull.Invoke();```

[median ruin]

What about the receiving end?

[wintry quarry]

you make a function

and assign it in the inspector to the event

[median ruin]

oh okay

wow this is handy

[unreal imp]

it doesnt works 😭

[wintry quarry]

what doesn't work about it?

[ivory bobcat]

Consider impulse if this is from the bullet and only a single instance of force should be applied.

[earnest atlas]

Why this values arent shown in Unity fields?

[wintry quarry]

They are properties

Unity only serialized fields

[ivory bobcat]

Those are properties

[wintry quarry]

you could add:

[field: SerializeField]``` to serialize the backing fields.

[earnest atlas]

So I need to make private values to be able to display them..

backing fields?

[wintry quarry]

yes

backing fields

auto properties have automatically generated backing fields

[ivory bobcat]

Maybe use field: SerializeField. Ah blue beat me to it.

[slender nymph]

you're already targeting the backing field with the Header attribute 🤔

[earnest atlas]

Those are just debug values so I can see them ingame

Issue is they are get; private set

[wintry quarry]

#💻┃code-beginner message

[slender nymph]

that's called a property as was already pointed out.
you knew to target the Header attribute with field:, did you not think to try that with the SerializeField attributes?

[earnest atlas]

funny enough im not sure what field does 🙂

I dont remember even from where I got it

[eternal needle]

Gpt?

[wintry quarry]

it targets the attribute at the backing field. as we've been saying

[earnest atlas]

Im pretty sure compiler reccomended it

[low path]

oof

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

accepting suggested stuff is good if you're sure it's what you want...

[earnest atlas]

Im running on my last braincells. It takes a while before I even get what you mean xD

[slender nymph]

then take a break and come back to it with a fresh mind

[earnest atlas]

My break will be going to sleep

I just want to finish logic behind enemy

[slender nymph]

don't force everyone to do your thinking for you just because you are too stubborn to take a break when you need to

[earnest atlas]

I mean I literally going to sleep in like half an hour

[rare basin]

programming when you are tired isn't a good idea

[earnest atlas]

Omg its alive

[eternal needle]

Its always "just want to do one thing". Tomorrow it will just be another thing
Take a break unless you are a slave at blizzard

[earnest atlas]

When I was playing factorio I had same "gonnado this and go rest"

that thing took 5 hours

[swift crag]

Get off the damn computer and take a break

You'll learn much more effectively that way.

[earnest atlas]

okey, gonna go sleep Ig

last thing

Why this no work

[slender nymph]

it is get only

[earnest atlas]

as I though

[low path]

can still set it in the inspector though i believe

[slender nymph]

incorrect. get only properties generate a readonly backing field which cannot be serialized by unity

[low path]

ahh

[fierce sonnet]

Hi, i am currently programming a evolution simulation 2d and i have problems programming the Raycast part of it

Code: https://gdl.space/zecinireyu.cs
The code runs in FixedUpdate

The problem is that even though (form what i can see with the DrawLines) they never turn green and even if they hit their target they sometimes if you wiggle them a lot maybe somtimes they see them. I have tried many youtube videos and asked also gemini but they couldn't help me
Thanks 🙏

[calm dust]

can sopmeone with codoing experience help me

im having trouble with my code

i cant find anything online to help

[river roost]

Are you sure it's not hitting the creature/agent itself?

[low path]

whats your quwstion?

[calm dust]

me?

[rare basin]

dont ask to ask

[fierce sonnet]

if i would shouldn't the rays turn green?

[rare basin]

send the code you are having issues with

how can we help you without any context

[calm dust]

fair enpough

[fierce sonnet]

if i am hitting how could i change it so i don't? should i add the the position maybe half of its scale?

[calm dust]

it is in playerinput but its not working

[spare mountain]

show us the code

[river roost]

Put it on a different layer and use a layer mask in the Raycast method

[slender nymph]

make sure that your !IDE is configured so that it will suggest properties that actually exist while typing the code

[spare mountain]

is onfootactions a... type?

why are you declaring a variable of type onfootactions?

[calm dust]

hold on

[spare mountain]

also you need to configure your ide

[calm dust]

i have more code

[slender nymph]

they've probably spelled the name wrong or not saved their input action asset

[calm dust]

yea i dont know how to do that

[spare mountain]

@calm dust

[slender nymph]

we don't need more code. configure your IDE

[calm dust]

ok

how do i do that?

[spare mountain]

🤦‍♂️

[calm dust]

oh wait

[low path]

i think they need to start with some c# basics tbh

[spare mountain]

we need some reading basics tbh

[dusty silo]

Does On(Dis/En)able apply to the object a script is attached to, or the script itself?

[polar acorn]

Yes

[slender nymph]

and yes, it would be a type (provided it is spelled correctly and they are using the correct PlayerInput type)

[river roost]

Both

[spare mountain]

thought so

[dusty silo]

Is there a way to specifically disable a script while leaving the object alone?

There isn't a check box next to scripts in the inspector

[slender nymph]

you can enable or disable a component using that components enabled property

[river roost]

set the enabled property to false

[polar acorn]

https://learn.unity.com/tutorial/enabling-and-disabling-components#

[slender nymph]

then that component does not define anything that is affected by being enabled/disabled (so no Update, OnEnable, etc)

[polar acorn]

There is if that script contains anything that can be affected by being disabled

[dusty silo]

Okay, thanks.

[calm dust]

ok, i configured it

[slender nymph]

do you see red underlines in your code now

[calm dust]

yes

[spare mountain]

yay

[spare mountain]

can you show the problematic code now

[slender nymph]

great! now remove line 4

[calm dust]

ok done

[slender nymph]

has the error gone away?

[calm dust]

no, another one came up

[slender nymph]

care to share? remember nobody here can see your screen

[calm dust]

sure, hold on

[spare mountain]

why would removing the importation of the inputsystem fix the error?

[slender nymph]

they are following a tutorial that generates a class called PlayerInput from their InputActionAsset. they want to use that class not the InputSystem.PlayerInput class

[spare mountain]

ahhh I gotcha

[swift crag]

ah

that name overlap is awful

[slender nymph]

congrats, you did not follow the tutorial correctly

[spare mountain]

rip

[calm dust]

lemme double check

[slender nymph]

keep in mind that spelling matters, including capitalization

[median mortar]

Hey guys, what kind of timers do you prefer in unity?
C# Timers (System.Timers), a simple Coroutine, C# Async?
Wanna set a timer that destroys an object if it doesn't hit anything in a specific time

[summer stump]

Is this that tutorial from Dave something (Dave Makes Games?). That one has caused so much confusion for people

[slender nymph]

probably the most annoying thing about that tutorial. most issues i've seen come from that tutorial are specifically because of the naming of that class

[median mortar]

Does Unity has its own Timer implementation?

[summer stump]

Definitely not system timers

[median mortar]

Why?

[summer stump]

Either accruing deltaTime, tracking differences in Time.time or a coroutine

[slender nymph]

just call Destroy in that object's Awake or Start method and pass the desired time as the second parameter

[calm dust]

i followed it exactly

[summer stump]

Because it runs on the system time which varies from game time

[slender nymph]

show the input actions and the inspector for the input action asset

[calm dust]

ok

hoild on

[median mortar]

Can I cancel that operation before time's up?

[slender nymph]

no but you never specified that 🤷‍♂️

[summer stump]

If you want cancellable, I would cache a coroutine and stop it with StopCoroutine if needed, or accrue deltaTime and halt it if needed

[spare mountain]

could invokes work?

invokes are cancellable

[slender nymph]

invoke is gross because it uses reflection, but yeah it would technically work

[spare mountain]

reflection?

[calm dust]

its not there

thats really weird

i will restart it

[median mortar]

Yeah, just wanted to clarify if I extend my use case 🙂

[calm dust]

@slender nymph

[slender nymph]

and the inspector when you've selected the input action asset

[calm dust]

i dont know what that means, im sorry

[polar acorn]

That's not named PlayerInput

[slender nymph]

you know the thing you double clicked to open that window? click that thing once and look at the inspector window

[spare mountain]

nor is their action map "onFoot"

[slender nymph]

the C# class's name is defined in the inspector, the name of the asset is irrelevant

[polar acorn]

But it defaults to the file name of the asset, and since they literally do not know what the inspector is, it's unlikely to have been changed

[slender nymph]

so you remember how i said spelling including capitalization matters?

you need to fix the class name either right there or in your code. then you need to spell the action name correctly in your code too

[calm dust]

i did that but the error is still there

[summer stump]

Which of the two things did you do?

[calm dust]

in the code

[summer stump]

What did you change it to? Exactly

[calm dust]

Playerinpu

[spare mountain]

did you make a typo or is it actually without a t in your code

[calm dust]

typo

[spare mountain]

ok

[polar acorn]

Well if you put this much care into typing your code as you put into Discord I can see where your problems are coming from

[calm dust]

funny

[spare mountain]

what's the error say now @calm dust

[summer stump]

And you did NOT change the asset here?
#💻┃code-beginner message

[spare mountain]

wait what does your code look like now

something is afoot

[summer stump]

You changed the wrong thing

[spare mountain]

that too

[summer stump]

Change the type, not variable name

And readvalue is not a thing

Remember that capitalization matters

[slender nymph]

they just have a whole bunch of spelling mistakes

[polar acorn]

Basically, instead of having us spell check everything for you one thing at a time, configure your !ide and go retype it all properly this time

[eternal falcon]

they just don't know how to use that

Then autocomplete should be catching these

[slender nymph]

they claimed to have configured it. we have no proof thtat they did

[spare mountain]

true

[calm dust]

well, i did what the website said. the website that the bot linked

[slender nymph]

screenshot your code

[spare mountain]

took the words out of my mouth

[calm dust]

just so you know, i did what @summer stump told me toi do and changed the other onej

[rich adder]

if i had a dollar every time..

[spare mountain]

let's not play the blame game

[calm dust]

no no no

not what m doing

[spare mountain]

show your codeeee

[summer stump]

What did I say to do?

[calm dust]

it looks different and im just telling u why

[calm dust]

you said " i did the wrong one"

[spare mountain]

it is configured at least

[summer stump]

Yeah, I said change the type

You did not do that clearly

Because in four places the type is still PlayerInput

[spare mountain]

😮‍💨

[summer stump]

I will give you one though. You changed ONE of the five places

[spare mountain]

make every PlayerInput -> Playerinput first of all like we said

[calm dust]

its back down to 2

[spare mountain]

second fix your variables

[spare mountain]

which 2

[calm dust]

sorry hold on

[spare mountain]

your first variable still has no name

and you didn't even do what we said 😭

[summer stump]

Still not all the Playerinputs have been changed

[spare mountain]

dudeeee

[slender nymph]

it's not that it has not name, they just changed the variable's name to the type's name

[summer stump]

EVERY place it says PlayerInput needs to be Playerinput

[spare mountain]

no the variable is literally
Playerinput = new Playerinput();

[calm dust]

ok

[spare mountain]

it has no name

[polar acorn]

Don't make a variable the same name as the type

[calm dust]

ok

[summer stump]

And the variable name is playerinput

[slender nymph]

because they put the type name there instead of their variable. they don't need a local variable there, they need to assign to their existing field of that type

[spare mountain]

ohhhh you're right my bad

[summer stump]

This damn tutorial man. This happens every time

[polar acorn]

I don't know why this particular tutorial is the one people who can't spell gravitate towards most

Seems like at least twice a week we have someone who doesn't name their assets right

[slender nymph]

pretty sure it's a super short one that just shows you how to do the stuff instead of explaining how and why you are doing the things

[summer stump]

bad but appealing

[calm dust]

i dont know what i should rename my variable too

[summer stump]

How about input

[calm dust]

ok

[polar acorn]

Literally anything you want

Call it Kermit for all it matters

[slender nymph]

you don't need to rename any variables. you need to be using your existing variable

[calm dust]

im getting different answers

i dont know what to do

[polar acorn]

As long as you aren't using the same name for your variable as your class you're fine

Which you had but then you changed because you didn't know what a type was

[slender nymph]

your code here is correct except for the spelling of the types and the spelling of the ReadValue method (which you have already fixed). You went and changed the type names and replaced the variable being used inside of Awake with the type name

[calm dust]

should i just restart?

[spare mountain]

you're so close

you've got like 2 minor issues

why restart

[calm dust]

ok

[polar acorn]

You need to learn the difference between a variable's type and a variable's name

Then you'll stop using one where you need the other

[swift crag]

A variable is defined by two things:

• The type of the variable is what it holds. int, float, MyComponent, GameObject
• The name of the variable is what it's called. counter, damage, targetComponent, myObject

A variable is declared by writing both the type and the name of the new variable:

SomeType someName = ...

On the other hand, this is not a declaration:

someName = ...

[low path]

honestly i think they could benefit from some short-ish but fairly intensive c# practice. like go do leetcode easy or exercism.io or something.

[calm dust]

ok, i changes the variable to input, changed hoppefully the right ones to input, but now theres 2 problems

[swift crag]

you'll have to show us what you actually did

[slender nymph]

rather see the actual code than screenshots of the error messages

[swift crag]

this is more wrong.

[summer stump]

You changed the type to input. That was just for the name

[polar acorn]

#💻┃code-beginner message

[summer stump]

Read what fen wrote earlier very slowly and thoroughly a few times
#💻┃code-beginner message

[polar acorn]

At this point it's clear you simply do not know enough C# to even receive answers. Hambones was right, you should learn enough C# to at least understand the explanations you're being given. Consider one of the things suggested by them or linked in the pins.
#💻┃code-beginner message

[spare mountain]

it's like flipping random switches

and hoping the light turns on

[calm dust]

so should i change the code to Playerinput input = new Playerinput

[summer stump]

No

That would make a local variable

[potent nymph]

I'm confused as to why this method requires a [Serializable] attribute on the class https://docs.unity3d.com/2020.1/Documentation/ScriptReference/JsonUtility.FromJson.html

[swift crag]

Correct. You can't just keep making random changes until it works.

[spare mountain]

I highly doubt they know what that is

[swift crag]

Internally, this method uses the Unity serializer

That's why.

[summer stump]

input = new Playerinput

[swift crag]

The Unity serializer only cares about things that are [System.Serializable]

[potent nymph]

as far as I've read, "Serializable" means I'm saving something as a file, which I'm not doing

[swift crag]

To serialize is to turn an object into data.

[summer stump]

That is not what it means

[swift crag]

It does not mean to write that data to a file.

You do frequently write that data to a file, of course

but serialization is also used for things like sending data over a network

[potent nymph]

but I'm not sending data over a network either
I'm actually receiving JSON

[swift crag]

You don't just directly copy a blob of memory over the network; you turn your object into data, send that data, and then have the other party unpack that data back into a C# object

[potent nymph]

shouldn't it be deserialization...?

[swift crag]

I am just giving examples of what serialization is.

And yes, you're deserializing data back into an object.

The type must have the [System.Serializable] attribute.

[turbid robin]

is there away to ask what scene to load? something like a pubblic variable?

[swift crag]

consider making LoadScene take a single string argument

[polar acorn]

In order for something to be de serialized, it must be serializable in the first place

[polar acorn]

Have your function take a parameter

[swift crag]

I believe you can then specify a string in the OnClick entry

[summer stump]

Pass the int scene index or string scene name

Edit: oh, I see what you mean now

[swift crag]

oh, do you mean you want to show a popup?

and get some user input?

[turbid robin]

pubblic class SceneName;

something like this?

[polar acorn]

how

how did you get that from what we said

[turbid robin]

i create the parameter

[summer stump]

You don't want a class

String or int

[swift crag]

that's a small blob of invalid syntax

[swift crag]

this is not a parameter. a parameter is part of a method's declaration.

[turbid robin]

using UnityEngine;
using UnityEngine.SceneManagement;
 
public class Button : MonoBehaviour
public str SceneName;
{
    public void LoadScene()
    {
        SceneManager.LoadScene(SceneName);
    }
}```
like this?

[swift crag]

public void DoThing(string something) { ... }

Don't just guess at syntax

Please

If you don't know what a word is, look it up

[turbid robin]

my luck was not at my side

[polar acorn]

dont just throw code in random places

[turbid robin]

i remember i did it once, i just dont remember what i did ahha

[polar acorn]

then look it up again

[turbid robin]

oh yeah now i remember

using UnityEngine;
using UnityEngine.SceneManagement;

public class Button : MonoBehaviour
{
    public string SceneName;
    public void LoadScene()
    {
        SceneManager.LoadScene(SceneName);
    }
}```
like this?

[summer stump]

No

[swift crag]

this is completely bogus syntax

you can't just randomly smash lines of code together

[turbid robin]

no? this this time i didnt try to guess

[summer stump]

Sorta closer, but misunderstanding the absolute most basics of programming

[rich adder]

lol

[polar acorn]

Please direct attention to the previous Billy Madison quote

[slender nymph]

there are beginner c# courses pinned in this channel. you should stop what you are doing and go through them all so you have a basic understanding of how to use the language

[summer stump]

Do methods go INSIDE a class or OUTSIDE

[swift crag]

This places a method outside of a class or struct, which is forbidden. You've also tried to declare a field inside of a method, which is also forbidden. LoadScene tries to use a variable that doesn't exist.

Hey, that's a lot closer

[turbid robin]

inside the class now

[summer stump]

That is one of the four major errors I saw.

Now, what are parameters? And where do they go?

[turbid robin]

it works

i put the prameters on the unity project

[swift crag]

This will work if you always want to go to the same scene.

you did not put the "parameters" on the "unity project"
