I dont know if this makes much sense but I have been tearing the internet apart trying to just figure this out

The whole idea is that a trigger can display a ui element (already got this figured out) and then from there you can hit a key to progress it? in a way between multiple diffrent ui elements you have sorted (like flipping through a book or comic in a way? or like going through dialouge) and then just hiding the element when done, if that makes sense??

I dont know what keywords id have to search up or any better way to look for this, and it seems so simple but I have been stressing over figuring this out for weeks at this point

[teal viper]

Well, what do you have so far?
It should be pretty easy to implement with an array/list of ui objects that you want to display and some timer in update.

[inland saddle]

I have a UI element that shows up on trigger enter for little interaction spots

one second let me figure out the format for sending code

oh yay!

thank you

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

public class pleasefuckingwork : MonoBehaviour
{
    public GameObject tool;

    void OnTriggerEnter(Collider hit)
    {
        tool.SetActive(true);
    }

    void OnTriggerExit(Collider hit)
    {
        tool.SetActive(false);
    }
}

its nothing special but it does the job

I will admit I am much more of a visuals guy so coding and everything is so completely new to me

My idea was that i could make an alternative version of this code that calls the hiding of the ui to the end of my ui sequence ?

I have a kind of similar system in my game for reading these mini books but thats set to button presses

[teal viper]

From the image you shared earlier, you want to scroll between the different ui objects on key press and then disable it, no?

[inland saddle]

mhm!

[teal viper]

The simplest way you can do it is have all the UI objects under a single parent that has a UI script. When you enter the trigger, activate the object with the script. Then in the script update query input and if the desired key was pressed, activate the next child object(or an object in a list). When there is no next UI object, just disable the root object.

[inland saddle]

ooo

ok, let me see if i can do this

thank you so much for the advice and direction!

[hot harbor]

I was wondering if this implementation of AStar looks like it's behaving correctly? There's only the grid existing on screen, and nothing beneath.

My current understanding is that the heuristic does not change based on if there's obstacles or not since it's "blind" in a sense

pink is obstacle and cyan is the steps of the algorithm; yellow is the final path taken

[west radish]

yes

[tulip nimbus]

How do i check if certain colliders touch each other? Whenever im using OnTriggerEnter/Exit/Stay it works for all colliders on the gameobject or all colliders in parent/children

I have a sword with a collider, and an enemy with 3 colliders:

ColliderR- Collider Trigger for player range detection
ColliderP- Collider for Physics
ColliderH- Collider Trigger for a Hitbox (This is what the Sword should be able to hit)

However, all of them are working, which is not what i want. This is the script on the Sword im currently using with an Interface:

private void OnTriggerEnter2D(Collider2D other)
{
  if (SwordCollider.IsTouching(other) && other.CompareTag("Enemy")) 
        { 
        IDamageable damageable = other.GetComponent<IDamageable>();

        if (damageable != null) 
        {
            damageable.TakeDamage(1);
        }
    }
} 
    ```

The sword script also basically has an Attack() function which dissables/enables the script whenever the player attacks.

Ive tried to put the colliders as Variable fields in the Inspector, but using something like: ``` if(other == ColliderH) ``` did not seem to work.

So how can i detect if SwordCollider is touching any, but only one, of the colliders?

What am i doing wrong?

[timber tide]

Could be a composite collider problem? Usually I try to keep stuff separated when doing multiple trigger colliders, making sure I have a rigidbody for each collider *collider for each game object, sorry!

Rather, the sword itself wouldn't have an RB, only colliders. Make a gameobject for each hitbox of the sword and stick a collider on that. The enemy will do the OnColliderEnter methods and check what hitboxes of the sword had made contact

I think that's what I do? Just woke up ;p

[tulip nimbus]

This is really good advice! Thank you! However isnt it quite expensive to have more RBs?

And do you think there is a way to access them trough code or is it done just trough the inspector

[timber tide]

You only need 1 rb, and that would be on the enemy. This is assuming your weapon is moved not with physics

[tulip nimbus]

oh okay

[timber tide]

because the enemy is the one who reacts to the sword hitboxes. The sword shouldnt care what enemy it hits

but for the most part, to use these trigger collider methods, at least one rigidbody must be present. But, you can set the rigidbody as kinematic if you don't need the physics.

techically all this collider stuff is physics related, but you're just using it for intersection detection

and the object that does have the rb on them will be the one who receives the callback for when there is an intersection.

[timber tide]

And, if you do want the sword to actually care what it hits for like deflection purposes, you can always let the enemy reply back to the sword to tell it that it had made contact.

one of many ways to do it

[gray pawn]

should i be getting errors?

[slender nymph]

absolutely you should. you haven't declared most of the variables you are using and you've got a bunch of things misspelled

[timber tide]

where's the tutorial you're following

[gray pawn]

https://youtu.be/f473C43s8nE?si=pGsmyOXItadLNUoz

its this one

[timber tide]

go over the video again

there's quite a bunch you've missed there

[gray pawn]

im guessing its this bit

[craggy hinge]

How do I get the X,Y coordinates of a mouse click? I'm getting weird inconsistencies with ScreenToWorldPoint. I am making a 2D game and I am trying to determine the int X,Y coordinates of where the player clicks on something. All of my interactable objects (dungeons, monsters, player, etc.) are stored in Vector3 lists:

public static List<Vector3> dungeonPositions = new List<Vector3>();

Using dungeons for an example, I currently get the clickedPosition and then round the X,Y into a new Vector3 which I use to compare to all dungeon positions. I do this because when I'm generating the dungeons, they're using int X,Y coordinates and the ScreenToWorldPoint gives a float.

if (Input.GetMouseButtonDown(0))
{
    bool withinInteractionRange = false;
    Vector3 clickedPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    int pOne = Mathf.RoundToInt(clickedPosition.x);
    int pTwo = Mathf.RoundToInt(clickedPosition.y);
    position = new Vector3(pOne, pTwo);
    BoardManager.CheckInteractionRange();
    foreach (Vector3 dungeon in Dungeons.dungeonPositions)
    {
      if (dungeon == position)
      {
      InfoGUI.EnableInfoGUI(position, "dungeon", withinInteractionRange);
      }
    }
}

This seems to work sometimes but about 3/4ths of the time it doesn't do anything. I am guessing the issue is where I'm converting the clickedPosition into individual integers but I'm not sure. Does anyone have any suggestions for how best to accomplish this? Thanks!

[slender nymph]

you probably want to floor X and Y from the mouse position to get the actual coordinate space that was clicked rather than just the nearest coordinate (which could be the next grid space over), but also unless each of the objects in that list only has a size of 1,1 (in grid space, not scale) then what you are doing won't work.
consider using something like the event system IPointer interfaces for detecting clicks on the individual objects instead of checking against every single object on the map for each and every click

[craggy hinge]

Thanks for the reply. I'm fairly certain everything on each grid is set to 1,1 - I'll attach a screenshot of the Structures grid I have. For IPointer interfaces, I'm not sure that would work because I'm not generating any new game objects at run time. Everything on the game board is currently stored in lists that I iterate through and work with across all of my scripts, updating the individual tiles on each grid via coordinates when I need to.

[slender nymph]

i don't know what your screenshot has to do with what you've said. but if you are using tilemaps and all of the objects are actually part of the tilemaps then you can use both the grid and tilemap to get the correct positions and the object at that position instead of using pointless lists

[craggy hinge]

Ah, I misunderstood what you meant about grid space not scale. I guess I'm not sure where to check what the grid size is? I have left them all on whatever their default is I guess.

[dreamy dune]

what is the best way to find another gameobject in the scene trough code?

[slender nymph]

i was specifically referring to the actual objects. if they are not each 1 unit wide and 1 unit tall then what you were doing would break down immediately even if it were almost correct

[modest dust]

Highly depends on what you're trying to do

[craggy hinge]

Where can I check that? On the sprite itself?

[dreamy dune]

i want to set the parent of my camera to follow a gameobject in my player

[slender nymph]

look at it in your scene. however as i've already pointed out, that is pointless because there are far better ways to determine what you've clicked on

[dreamy dune]

is using findbyname good solution or not stabel?

[obsidian plaza]

transform.parent

if the parent changes then do that

[dreamy dune]

allright

[slender nymph]

use a better way to get a reference than any of the Find methods

[obsidian plaza]

but if its always the same then u can save some power by getting a reference

[dreamy dune]

its for using in multiplayer

[obsidian plaza]

that doesnt rly explain

[craggy hinge]

Thanks, I'll look further into those docs. I'm using the lists because there is a lot of data attached to everything and it allows me to manage it. Coming from a programming background, it made sense to me to use them to manage the tiles as well.

[dreamy dune]

so i have my player object and a camera object and when i join server i need to have a ref to the camera object

[modest dust]

You technically can, but it's not an optimal solution by any means

[dreamy dune]

allright thats what i thought

[modest dust]

Is the camera ever used without the player being present?

[dreamy dune]

not really

[obsidian plaza]

oh wait

u could just add it to the prefab

wait not that wont work

[modest dust]

Then you don't need to find anything at all, just add it to the prefab

[obsidian plaza]

still cant pass reference

[modest dust]

Unparent it later if you need to

[obsidian plaza]

can u

[hexed terrace]

Assuming you only have 1 camera in the scene .. Camera.main

[dreamy dune]

allright i thought that wasnt a good solution to add camera to player

[dreamy dune]

i need to have the parent and the camera

[obsidian plaza]

what

[hexed terrace]

Camera.main.transform.parent

[dreamy dune]

thank you

[vocal urchin]

I'm literally just trying to make a pinball table but never done 3d before. Should be easy for a 3d expert 🙂
Any idea why my flipper keeps snapping back to 45 degrees rotation on the X axis?

    public Rigidbody rigidBody;
    public Quaternion defaultRotation;
    public Vector3 targetRot;


    
    void Start()
    {
        if (flipperType == FlipperType.LEFT)
        {
            FlipperController.instance.OnLeftFlipperActivated += ActivateFlipper;
            FlipperController.instance.OnLeftFlipperDeactivated += DeactivateFlipper;
        }
        else
        {

            FlipperController.instance.OnRightFlipperActivated += ActivateFlipper;
            FlipperController.instance.OnRightFlipperDeactivated += DeactivateFlipper;
        }
        //defaultRotation = rigidBody.rotation;
    }

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

    private void FixedUpdate()
    {

        rigidBody.MoveRotation(Quaternion.Euler(0, targetRot.y, 0));
    }

    public void ActivateFlipper(float angle, float flipTime)
    {
        float a = Mathf.LerpAngle(rigidBody.rotation.y, angle, flipTime * Time.deltaTime);
        targetRot = new Vector3(rigidBody.rotation.x, a, rigidBody.rotation.z);
    }

    public void DeactivateFlipper(float angle, float flipTime)
    {
        float a = Mathf.LerpAngle(rigidBody.rotation.y, defaultRotation.y, flipTime * Time.deltaTime);
        targetRot = new Vector3(rigidBody.rotation.x, 0, rigidBody.rotation.z);
    }

    public enum FlipperType { LEFT, RIGHT };    
}```

This is how the flipper is set up

[verbal dome]

Rigidbody.rotation is a Quaternion, but you are treating it as euler angles apparently

Quaternion.x/y/z dont make sense here

[timber tide]

oh yeah good catch, similarly you're using lerp angle on two quaternions... does that even work

I mean, you got the idea of rotating on the y, and that's all you need to do really if it's only rotating one axis.

[vocal urchin]

ooooh

so I want rigidbody.rotation.eulerangles?

[timber tide]

Ye. Personally I would just pivot the flipper in a position and have two y values it could possibly be at so I only need to lerp a float.

[vocal urchin]

I think I really need to learn what a quaternion actually is

[grand snow]

[inland saddle]

took another swing at this using what I understand but not dice

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UIElements;

public class KeypressManager: MonoBehaviour
{
    public GameObject dialouge01;
    public GameObject dialouge02;
    public GameObject parent;

    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown("enter"))
        {
            dialouge01.SetActive(true);
        }

       if (dialouge01.activeSelf) {
                if (Input.GetKeyDown("enter"))
            {
                dialouge02.SetActive(true);
                dialouge01.SetActive(false);
            }
        }
        if (dialouge02.activeSelf)
        {
            if (Input.GetKeyDown("enter"))
            {
                dialouge02.SetActive(false);
                parent.SetActive(false);

            }
        }
    }
}

doing this feels so deceptively simple and just I really am trying

[shy kite]

looks alr

i suppose you slowed it a bit for showcase

[inland cobalt]

If i want a class to inherit from multiple things, such as this:

public partial class Enemy : Poolable<Enemy>, Damageable<Enemy>
{
  //...
}

How can i best go about doing it? As it cannot have multiple base classes

[slender nymph]

based purely on name alone Poolable<T> and Damageable<T> seem like they should probably be interfaces, but you've not really provided enough context to know for sure

[cosmic dagger]

Those definitely sound like interface names. You can only derive from one class, but you can derive from multiple interfaces . . .

[inland cobalt]

I see, i made them abstract as i wanted to provide default implementations for them, so i thought that was best. As far as i know i cant define variables in an interface so im not sure how to go about it otherwise

[slender nymph]

you can have properties in interfaces. what is the actual purpose of these and why do you need both

[inland cobalt]

public abstract class Damageable<T> where T : MonoBehaviour
{
    public float Health { get; private set; }

    public virtual bool Damage(float damage)
    {
        Health -= damage;
        if(Health < 0) 
        {
            Die();
            return true;
        }

        return false;
    }

    protected abstract void Die();
}```

example

[timber tide]

I'd make IPoolable an interface for the Enemy to inherit implement

[cosmic dagger]

Then, you need to rethink your architecture. You shouldn't have a big inheritance chain . . .

[cosmic dagger]

This should be a separate MonoBehaviour class that you attach to the enemy GameObject . . .

[ivory bobcat]

private void Update()
{
    if(...Down...)
    {
        dialogues[current].SetActive(false);
        current++;
        if(current >= dialogues.Count)
        {
            enabled = false; 
            return;
        }
        dialogues[current].SetActive(true);
    }
}```

[slender nymph]

yeah honestly that should be its own component and the Die method should just be a UnityEvent that you can subscribe to in the inspector from your separate Enemy component
there's also 0 reason that should be generic

[timber tide]

here's an idea too

public abstract class ObjectPool<T> where T : MonoBehaviour {} //Can also make this a monobehaviour class / singleton to child the enemy instances
public class EnemyPool<Enemy> {}```

[cosmic dagger]

In Unity, it's best to create separate components that when added to a GameObject, provide it functionality, which ultimately, builds that object . . .

[inland cobalt]

I see, is something like this fine though?

[DefaultExecutionOrder(-1)] // Ensures singletons can always be accessed by prioritising their execution
public abstract class Singleton<T> : MonoBehaviour where T : MonoBehaviour
{
    private static T instance;
    public static T Instance
    {
        get
        {
            if (instance == null)
            {
                T[] instances = FindObjectsByType<T>(FindObjectsSortMode.None);
                if (instances.Length > 1) Debug.LogWarning($"Multiple instances of {instance.name} exist");

                if (instances.Length != 0) instance = instances[0];
                else Debug.LogWarning("Singleton is attempting to be accessed, when none exist");
            }

            return instance;
        }
    }
}```

This was the first time i used this kind of format, so i just replicated, i feel like it makes sense here

[inland saddle]

im sorry to be a bother, could i ask for a bit of a clarification on the down or how to properly set up this script?

im sorry

[inland cobalt]

I see what you mean how it makes sense for damaging and stuff to be in seperate monobehaviours though

[ivory bobcat]

You'd just ask. The down within the if statement is me being lazy and not wanting to type it all out (I'm on mobile)
Dialogues would be a list of type Dialogue.

Or GameObject or whatever you're needing more than one of.

public List<GameObject> dialogues;//to be populated from the inspector etc```

[cosmic dagger]

The Singleton looks fine, but it's incomplete. You never assign it (in Awake) or check if one already exists, and if there is none, you should load it from your assets and return that instance . . .

[ivory bobcat]

I'm assuming you know about lists and have imported the directives (using collection etc)

[timber tide]

I don't understand the object search. You just check if theinstance is null or not

[inland cobalt]

well the idea was that these would already exist on game start and that was just ensuring a single one exists when other scripts try to access it, i think i got help from someone here ages ago for it.

[inland saddle]

not atall

[inland cobalt]

well i was doing that as a check for only one instance existing in the scene, but i get its not necessary really

[timber tide]

public abstract class Singleton<T> : MonoBehaviour where T : MonoBehaviour
{
    public static T Instance { get; private set; }
    
    protected virtual void Awake()
    {
        if (Instance == null)
        {
            Instance = this as T;
        }
        else if (Instance != this)
        {
            Destroy(this); //Or destroy gameobject depending how you do your managers
        }
    }
}

public abstract class PersistentSingleton<T> : Singleton<T> where T : MonoBehaviour
{
    protected override void Awake()
    {
        base.Awake();
        DontDestroyOnLoad(gameObject);
    }
}```
```cs
public class GameManager: PersistentSingleton<GameManager>```
There, toss that into every project

[inland cobalt]

Alright, thanks. With regards to my damageable, how would i want to go about overriding behaviour if i made it a separate monobehaviour script as suggested, without repeating code?

[timber tide]

public interface IDamageable
{
  public int Health { get; }
  public void DoDamage(int damageAmount);
  public void DoHeal(int healAmount);
}```

[ivory bobcat]

Place this at the top using System.Collections.Generic; to allow yourself usage of Lists.
Create the public List field like my prior example above.
Populate the list with your dialogues. For example, if you had three dialogues, they would be at index 0, 1 and 2 of the list.
The code would run in Update and evaluate if said button was pressed (the statement where I've neglected to complete since you've already done so yourself in your original code posted).
Next you would disabled the current dialogue (assuming the current one is enabled when this script had become enabled). You'd increment the counter (current) by one and evaluate if it's less than the maximum amount of dialogues. If greater than or equal to the maximum count, you'd disable this script to prevent further execution at later times and stop executing the remainder of this Update function with a return call.
If the current index hasn't exceeded the series of dialogues to be presented you'd enable the next one etc.

[inland cobalt]

In anything that uses that interface, DoDamage would take away health though, so wouldn't that just lead to unecessary repeated code? Or is that just the case and theres no good way around it?

[inland saddle]

Thank you so much, I will try my best to follow along

[timber tide]

Depends, do you think every single object will have the same method logic? If a player takes damage, wouldnt they also invoke say invincibility frames, but not enemies?

[cosmic dagger]

Each object that implements the method will have it's own logic. Yes, some of them will be the same (trivial), but not every object . . .

[inland cobalt]

I suppose that's a fair point, thanks

[ivory breach]

I tried to make my turret aim at the player with the following method, but when the player gets too close to it, the turret doesn't aim like the game is 2D. Is there a way to fix this issue?

    private void LookAt()
    {
        Vector3 targetDir = GameObject.FindWithTag("Player").transform.position - gun.transform.position;
        float step = rotationSpeed * Time.deltaTime;
        Vector3 newDir = Vector3.RotateTowards(gun.transform.forward, targetDir, step, 0.0f);
        gun.transform.rotation = Quaternion.LookRotation(newDir);

        //gun.transform.rotation = Quaternion.Euler(gun.transform.rotation.eulerAngles.x, 90, 0);
    }

[timber tide]

public interface IDamageable
{
  public HealthComponent HealthComponent { get; }
}```
Not saying you can't do it how you want it though. Just think with composition

[hexed terrace]

Set the Y(?) value of newDir to 0 before setting the gun transform rotation

Also, stop using FindWithTag() constantly. Do it once and cache it.. there is no reason to do it every frame

[ivory breach]

Idk how I can do that, can you show me?

[ivory breach]

Ok

[hexed terrace]

newDir.y = 0;

[ivory breach]

I'll try it

[hexed terrace]

ok, great - I dont need to be told that, just go do it ;p

[ivory breach]

Update: Now it doesn't even look up anymore

Where did I go so wrong...

[hexed terrace]

I dunno, because you haven't shown what changes you've done.

[ivory breach]

All I did was add your suggested piece of code here

If I'm missing something, please let me know

[hexed terrace]

Remove that line I said to add.. and wait for someone else to help. I dont have the time to carry on.

Seems to me though you only want to be rotating on Z, but you're rotating on all three axis

[wintry quarry]

Just pass in Vector3.back as the second parameter to LookRotation

Quaternion.LookRotation(newDir, Vector3.back);

the problem right now is you're not passsing in a second parameter, so the game assumes you want the global "up" direction to be the "up" direction for your rotation

[ivory breach]

Nope, it still rotates on all three axis somehow

[wintry quarry]

wdym by "rotates on all three axis"

show a video

[ivory breach]

I've made sure all of the rotations including the children are set to 0

[ivory breach]

Same issue as my initial problem

[hexed terrace]

@wintry quarry

[wintry quarry]

the only issue I see is the twisting

oh I didn't watch long enough

your problem then is also that the objects are not at the same z position

so you will also want dir.z = 0;

[swift crag]

that means that the turret and player aren't on the same plane

i'm mildly unclear which plane the camera is aligned with; assuming it's the XY plane, then yeah, zero out the Z coordinates

[wintry quarry]

newDir.z = 0;
gun.transform.rotation = Quaternion.LookRotation(newDir, Vector3.back);```

[swift crag]

the commented-out code has the gun rotating on the world X axis

[wintry quarry]

yeah this is assuming we're looking at the xy plane here

[swift crag]

which is inconsistent with being aligned with the XY plane

if the camera is on the YZ plane, then zero out the X coordinate. Same idea.

you can figure out which plane the camera is on by looking at the orientation gizmo with your view aligned with the camera

here, I'm on the XY plane

...and looking in the +Z direction

[wintry quarry]

actually it's probably targetDir we want to be setting z = 0 on tbh

[swift crag]

Yeah, you can zero out both positions or the resulting direction

Same deal

The latter is easier

[ivory breach]

That was it! Thank u so much!

[swift crag]

note that this means that the cannon is no longer aiming at the player 😉

Maybe you actually want to fix the player not being on the same Z coordinate as the cannon!

[ivory breach]

I'll make sure all of the objects' z coordinates are at zero next time

@swift crag Btw, it's the xy plane in my case

[swift crag]

yeah, that's the typical setup for a 2D game

i was just unsure because of that commented-out line at the end

[ivory breach]

Now to figure out how to clamp their rotations to prevent the turrets from looking down

[swift crag]

Quite a few ways to do that. The most obvious, to me, is to use Quaternion.RotateTowards

That lets you move from one rotation to another by at most a certain amount

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Quaternion.RotateTowards.html

[ivory breach]

Are you talking about maxDegreesDelta?

[swift crag]

Yeah

so Quaterion.RotateTowards(Quaternion.identity, targetRotation, 90) produces a rotation that is at most 90 degrees away from the identity rotation

"identity" meaning the rotation that does nothing

transform.localPosition += Vector3.zero;
transform.localRotation *= Quaternion.identity;
transform.localScale *= Vector3.one;

all three of these do nothing

[fierce plume]

How do I Reference or just use a variable from another script?

[thorn holly]

Use serialized fields or something else to get a reference to that instance of the script, then just say ClassName.variable. Make sure the variable is declared as public

[hexed terrace]

dont declare variables as public, its poor encapsulation

[thorn holly]

In that case, use a getter/setter method

[hexed terrace]

Yes, use them. Getter/ Setter is a property though - not a method

[vital barn]

Inside is method

[hexed terrace]

it might decompile to a method, I dunno, but in your C# class.. it's not a method, hence why theyre called properties

[thorn holly]

Well I mean it depends on how you write it

[grand snow]

Properties actually make a get and set function but it's hidden from you

If you use reflection you can find these methods and the backing field

[vital barn]

Or just use dnspy

[ivory breach]

Looking back at my code, I honestly don't know how to change this line of code to clamp the x-axis rotation, because the maxDegreesDelta is already taken by "step"

Vector3 newDir = Vector3.RotateTowards(gun.transform.forward, targetDir, step, 0.0f);

[vital barn]

eulerAngles

[thorn holly]

I’d say set the rotation in Euler angles and do the math yourself

It’ll give you more control, including clamping a specific axis

[ivory breach]

This is the only method I was able to find so far in order to make that turret aim at the player like it's a 2D game

If u can suggest a better solution, I'm all ears

[swift crag]

aren't you only rotating on one axis?

the Z axis, in particular

[ivory breach]

Yes

[swift crag]

Don't start from the current rotation

[SerializeField] Quaternion centerRotation;
[SerializeField] float angleLimit;

Rotate from centerRotation towards the desired rotation by at most angleLimit

where centerRotation is the rotation that makes the cannon point straight up

[ivory breach]

Upon closer inspection, I found something weird with the object's rotation

[swift crag]

also, this is Vector3.RotateTowards, not Quaternion.RotateTowards

You can certainly achieve the same thing with it, though

You'd just store a neutral direction that you rotate away from

[ivory breach]

The object is apparently rotating in the x-axis instead of z-axis, and depending on where it's pointing, the y and z rotation snaps to 90 and -90 degrees when it's looking right and vice versa when it's looking left

[swift crag]

note that you're looking at local rotations in the inspector

if you rotate an object around the world Z axis, its local X rotation might change (depending on how its parent is rotated)

also note that looking at Euler angles can be misleading

there are many ways to represent the same orientation

If the cannon is visibly doing the right thing, that's all that matters

[ivory breach]

So the z rotation is correct, but doesn't display it the same way in the inspector as it's using euler angles

[swift crag]

because the inspector is showing the rotation relative to its parent

[wintry rampart]

I am trying to learn this engine i never used anything of this before i am trying to use the tutorial but i dont under stand this can anyone help?

[polar marsh]

Anyone know how i can resolve this error? My script name matches the class name and it inherits from monobehavior, but it just refuses to recognise it

[swift crag]

Do you have any compile errors?

[ivory breach]

I've made sure the parent's rotation is zero on all axis

[swift crag]

You probably need to go into the "FPS" folder, but I'm just guessing here

[polar marsh]

Not as far as i know, rider isnt picking anything up

[swift crag]

make sure you haven't skipped a step

[swift crag]

You must have zero errors in your entire project

Check the console.

[polar marsh]

Even if i delete all the code from the script it still does it

[swift crag]

that leaves the second reason: euler angles aren't unique

[polar marsh]

There's nothing in the console

[swift crag]

hm, at that point: right click the script asset and click "Reimport". Does anything change?

also make sure that you don't have multiple MonoBehaviour classes defined in the same script file

[polar marsh]

Nope

It's just one class as well

[swift crag]

can you currently enter play mode?

[polar marsh]

Yep it works fine

[swift crag]

Peculiar.

I'd sanity check by making a new MonoBehaviour script asset and seeing if that works

If that fails, I'd see if a full reimport fixes it. Assets > Reimport All

[polar marsh]

Doesn't seem to work either

[swift crag]

this'll take a hot minute

[polar marsh]

Alright ill try that

[swift crag]

the more violent version of this is to close the project, delete the Library folder, and reopen the project

the Library contains data generated by Unity -- a big chunk of which is the asset database

that's what you're clearing with Reimport All

[polar marsh]

Oh i see okay

[swift crag]

As for why the local X axis is changing here -- the Y rotation affects the meaning of the X and Z rotations

(and the X rotation affects the meaning of the Z rotation)

When you only have a direction, there are many possible rotations that point you in that direction

which could cause unwanted spinning of the barrel

I see that you were originally not passing a second argument to LookRotation

Are you doing that now?

[fathom cape]

Hello o3o

I have a question I will place in a thread if I can

[ivory breach]

If the second argument was Vector3.back, yes

[polar marsh]

Okay it worked ty

[swift crag]

Okay, that's good

That'll keep the barrel's "up" direction -- the green arrow -- facing towards the camera

[ivory breach]

How do I find the turret's local quaternion rotation? Because I want to find its center rotation and I don't trust the rotation values in the inspector anymore

[ivory breach]

I'm talking about this one

[swift crag]

which direction does the barrel point when its local rotation is zero?

You actually want to be working with local rotations here. If the entire cannon body tilts to the side, that should change the field of view of the cannon

[swift crag]

So, your code will look like this:

[SerializeField] Quaternion restRotation;
[SerializeField] float angleLimit;

void Aim() {
  Quaternion goalRotation = ... // do the existing calculation
  
  Quaternion localGoalRotation = Quaternion.Inverse(transform.parent.rotation) * goalRotation;

  Quaternion limitedRotation = Quaternion.RotateTowards(restRotation, localGoalRotation, angleLimit);
  
  transform.localRotation = limitedRotation;
}

Get the barrel rotated to the neutral position, then right click the "Rotation" property and copy the quaternion. You can then paste it into the restRotation field.

I wish there was a convenient Transform method to go between local and world rotations

goalRotation is a world-space rotation. The second line converts to a local-space rotation.

[ivory breach]

Here are the cannon's rotations in the inspector just to be sure

[swift crag]

Rotate the barrel so that it's in the "center" position

then copy its local rotation

that's your reference point

the cannon will rotate away from that reference point until it reaches the angle limit

[humble hound]

hii can anyone help me

i have two jumps, when i jump once it the ball only moves 2 pixels above the ground and it sticks back to the ground coz the gravityon air brought it back down, the ball jumps nicely when on air so the gravityscale on air os not the problem, but there is something happening between that first jump that makes the ball only jump 2 pixels idky

[swift crag]

perhaps you have code that sets your vertical velocity to zero when you're grounded

and the ground check is wrongly saying "yes" when you're moving upwards

[ivory breach]

@swift crag I hope I did everything right

void Aim() 
    {
        Vector3 targetDir = GameObject.FindWithTag("Player").transform.position - gun.transform.position;
        float step = rotationSpeed * Time.deltaTime;
        Vector3 newDir = Vector3.RotateTowards(gun.transform.forward, targetDir, step, 0.0f);
        newDir.z = 0;

        Quaternion goalRotation = Quaternion.LookRotation(newDir, Vector3.back);
  
        Quaternion localGoalRotation = Quaternion.Inverse(transform.parent.rotation) * goalRotation;

        Quaternion limitedRotation = Quaternion.RotateTowards(restRotation, localGoalRotation, angleLimit);
  
        transform.localRotation = limitedRotation;
    }

[swift crag]

That seems right. Just make sure that the green arrow on the barrel is pointing towards the camera in the rest position

(make sure your scene view is in "Local" mode, not "Global", here)

Otherwise, the barrel will try to spin around its long axis!

[ivory breach]

Should I attach the script to the barrel or its parent?

[swift crag]

As-written, it needs to go on the barrel

If you want to be able to put it on another object, you need to add a Transform field

(and then rotate that target)

basically, any use of your own transform property would be replaced by that field

[ivory breach]

I'll just put in on the barrel to play it safe

@swift crag Yeah! It's working!

[swift crag]

nice (:

You should be able to rotate the entire cannon body and have it still work right

[ivory breach]

Thx a million!

I need to get to work so I'm out of here for now, but someone else can probably help you with that

[wintry quarry]

I mean... a functioin called "StickToSurface" with m_Rigidbody.linearVelocity = Vector2.zero; // Stop all movement
seems pretty suspicious.

[ivory breach]

@swift crag Btw, the cannon ur talking about is actually a mortar

I just suck at designing it to make it look like one

[humble hound]

because i want it to stick to surface when im not movind, it kept rolling

Im tryna recreate this feature man

[wintry quarry]

How are you gonna stick to a rotating triangle by setting your velocity to 0?

the approach is misguided

aand anyway it's responsible for your inability to properly move off the surface

[humble hound]

How would you approach it

[wintry quarry]

Probably without rigidbodies

[rich adder]

wouldn't you use something like a joint ?

[wintry quarry]

parent the player to the object it contacts

but yeah with RB you would use joints and break them when the player jumps again

but it won't be exact and clean

because physics isn't

[rich adder]

test it out, if dynamic gives you problems, maybe use transforms or kinematic parenting

[humble hound]

Parent the object everytime the ball jumps on a surface

[rich adder]

only when necessary I suppose, idk the full mechanics of the game

[humble hound]

Really wont that cause unintended issues like the object jumping with the ball

[rich adder]

when you jump you break the connection

only put it on while its a moving / rotating surface I guess

[humble hound]

I just want my ball to jump and stick to an object

[rich adder]

No I understand that part, but idk also movement and stuff to consider, like are you able to move while its rotating or you're supposed to stay stil ?

the former complicates this even further

[scarlet hull]

i have a character 3d model any website or some tool to just auto rig it and apply animations?

[humble hound]

So what do you think i do

[rich adder]

tbh I have no idea, haven't experimented too much with 2D.. You can try joints at least for sticking, maybe you can figure out a way for movement

[ruby python]

Af'noon all.......sooooo, I'm trying to get the pixel colour values of an image but ran into a bit of a roadblock.

Here's my full code at the moment

https://hastebin.com/share/liradisati.csharp

The part that I'm struggling with at the moment is where I assign the colour value of the current pixel in my loop

newDepthMapData.valueAtPosition = depthMapValues[  ];

This line specifically, I don't really know what this should be if honest, and the Unity docs have been no help so far.

Idea of the script is that it reads each pixel in turn and creates/adds the data (current position and pixel colour value) to the DepthMapData class and then adds the new class to the list for future processing etc.

Chances are that I've done many things wrong with how I've written in all, but at the moment it's just for prototyping purposes.

Would anyone be able to point me in the right direction please?

[polar acorn]

I believe depthMapValues should be a straight array of pixels, top left to bottom right, in order. So, to get the position x,y from a 1D array this way, you would get the position at index (x * width) + y

[ruby python]

Ah excellent, thank you. Yeah I was very confused as to what went in there. lol. Will give this a go 🙂

[polar acorn]

Fun fact - this is actually how 2D arrays are stored in memory. There's not actually multidimensional arrays, just syntactic sugar that does this math for you.

[ruby python]

Aah, fair enough. 🙂

And dangit, I was declaring valueAtPosition as a float, and not a Color32. lol.

rb.velocity = motion * speed * Time.deltaTime; using deltaTime for velocity is wrong and the source of your problem

[steep hollow]

lemme try

[rich adder]

also might want to be moving in FixedUpdate

[steep hollow]

THX

it worked

[swift crag]

you use deltaTime to convert "X per second" into "X"

[ruby python]

Hmm. Okay, so everything is now working......sort of. lol. I'm grabbing the correct data from my image and it's all being added to the list correctly, which is cool.

But, I'm getting an index out of range error, and I'm not entirely sure why.

https://hastebin.com/share/ehaqaniwen.csharp

I'm sure there's a better way to do this tbh, as it is going to result in a crapload of entries in the list (80,000 ish before the index things craps it out and if my maths is right, it should be 147,456, which I'll then have to search through on a frame by frame basis, which I imagine will be very slow.

The image is 512*288 pixels.

[wintry quarry]

on what line are you getting the error

Anyway pretty sure:

depthMapValues[(x * mapWidth) + y];```
is supposed to be:
```cs
depthMapValues[(x * mapHeight) + y];```

and the -1 should probably not be there e.g. in mapWidth-1 unless you are trying to skip the last pixel in each row/column

[ruby python]

Color32 tempColour = depthMapValues[(x * mapWidth) + y];

[swift crag]

generally speaking, you should have:

x * y_size * z_size + y * z_size + z

[ruby python]

Ah okay. Yeah that's the line with the error.

[swift crag]

incrementing x skips ahead by an entire YZ slice

[ruby python]

And yeah, the -1 was just 'checking' with the out of range error.

[swift crag]

in this case, you just have x and y

[ruby python]

Fantastic, thank you. This was the issue. all fixed now 🙂

[wintry quarry]

Fen's reasoning is the why!

[ruby python]

Yeah, I'll be honest, the axes stuff in that line confuses the crap out of me. lol.

Actually, if I may impose a little further. I've figured out how to cut down on the list entries quite a bit (using an alpha channel and just ignoring anything with an alpha of 0. So that helps.

When it comes to referencing the data in the list and grabbing the colour value, I'm not 100% sure how to go about it.

My thought at the moment is to send Input.mousePosition (with a little calculation to match the size of the depthMap image) to a method that searches the list for the relevant vector2 and returns the colourValue, which will then be used to scale the bullet impact.

But, it seems like that might be really inefficient and slow.

Anyone have any thoughts?

[shut warren]

Hello, i'm trying to make my player respawn after his death, but he isn't respawning at all. I followed all of my tutorial and there is no errors. Here is my code : https://paste.mod.gg/wgafbhcljceh/0

[ruby python]

By the looks of it, You're destroying your player (deleting it), but never actually Instantiating it again.

[eternal needle]

add some debugs and find out which logic is going wrong. If I had to guess, u didnt assign _respawnPosition and then line 40 is false

also this code is very questionable, id be pretty wary of this tutorial.

[polar acorn]

Do you get your log for player lives remaining

Ignore what I said btw. Speed reading and read it wrong. lol.

[normal turret]

Hey guys, what's up

If I want to do a fake collider on one tile in my tileset, how can I do that...?

[wintry quarry]

wdym by "fake collider"?

[normal turret]

Someone recommended I should make a fake collider on another server because I was having issues with wall-jumping

[wintry quarry]

WHat does that mean

what kind of issues?
What would a "fake collider" do or mean?

[normal turret]

Like for these steps for example, it thinks these tiles are walls

[shut warren]

Yes

[vital barn]

It shold be trigger

[normal turret]

I only want to wall-jump if it's 2 tiles or higher

[polar acorn]

Does your player have a Character Controller on it

[normal turret]

I guess it's like another collider that you can add to fix bugs in the engine...?

[shut warren]

Yes

[polar acorn]

What bugs in the engine?

[wintry quarry]

Sounds completely imaginary.

and yeah what bug?

[normal turret]

Like sometimes there can be issues with the character moving up a slope, you can add a fake collider and make it seamless

I don't know, I'm new to this stuff too, I just heard the concept a couple days ago

[polar acorn]

CharacterControllers don't like being teleported. You can either disable the controller and re-enable it, or call Physics.SyncTransforms() after the teleport to force it to update

[polar acorn]

Still not sure what you mean by "fake collider"

[wintry quarry]

There is nothing in Unity called a "fake collider"

maybe what they mean is to add a simple collider that doesn't match the visual shape of the terrain?

[drifting cosmos]

do you want them to walk like theyre walking up a triangle or something

[normal turret]

This is what the person shared as a solution

[wintry quarry]

yeah that's just having a collider that doesn't perfectly match the visual

[polar acorn]

Okay, yes, a collider that doesn't match the visuals

[barren plume]

I copied a script I found from youtube video regarding player collisions and movement and I noticed that some of the words werent the right colors and stuff how do I fix this

[wintry quarry]

You can edit the shape of the collider for your sprites in the Sprite Editor under "Custom Physics Shape" @normal turret

[normal turret]

Yeah that's what a fake collider is I think

im trying to write somethig like this but im writing in pixel size not unit size

[barren plume]

I did this and its still not working so either my pc is stupid or I am

[wintry quarry]

no because pixel size is not constant in the world

when your game resoluition changes it will be different

If you mean something like sprite pixels rathjer than actual on-screen rendered pixels then yeah you would use e.g. the sprite pixels per unit as in that code to convert

if you have 32 PPU, for example, then 1 in-game unit = 32 "sprite pixels"

i did smth like this

[cosmic charm]

Is it possible to make the cloud respond to the player's steps, so that it sinks when the player steps on it and sinks further if the player lands on it after jumping?

[drifting cosmos]

anything is possible

[swift crag]

some things are just very, very annoying (:

It sounds like you have a couple of smaller problems here:

• Detecting that the player is standing on a cloud
• Detecting that the player just landed on a cloud
• Warping the shape of the cloud

[cosmic charm]

this should be made through code, right? it's not about animation? like it would be dumb to make a version for each cloud depending on the the player's movement

[drifting cosmos]

is it a tileset cloud

[timber tide]

you can do it by animation

[drifting cosmos]

yeah might be really easy

[timber tide]

but this is simple enough to just do it all in code

[cosmic charm]

it won't be pixel pefect

let me explain

[swift crag]

hm, i'm not sure about how I'd distort the individual sprites in a tilemap

since that's one big mysterious Tilemap Renderer

[timber tide]

Can't you mix both? Tilesets and just single GOs?

Didn't even occur to me that you can use tileset for 2D platformers ;p

[cosmic charm]

like what if he wasn't in the middle of the cloud?

[drifting cosmos]

well if its a tile set

like you could have 3

animations

and since the guy is big enough you wont need more

[cosmic charm]

like I was thinking of implementing the same logic of the water

[drifting cosmos]

does it go back

to like flat

[cosmic charm]

yes

can I send links here of a youtube tutorial?

or will i get banned?

[drifting cosmos]

idk but i think you can have smaller tiles so like for the water one you can have the middle tile the one all the way down and the ones on the side you can have them in a different state

what do you think if i change the script to only affect horizontal velocity so that the ball stops rolling when its on the ground instead of stopping all velocity

m_Rigidbody.linearVelocity = new Vector2(0f, m_Rigidbody.linearVelocity.y);

[wintry quarry]

same problem

agian look at that rotating triangle part

that's not going to work with some hardcoded velocity hack

[slender nymph]

this is not related to your issue but fun fact: if you are on a version of unity where the velocity property is called linearVelocity then you also have access to the linearVelocityX and linearVelocityY properties to only assign a single axis instead of both
(for anyone else reading this, this only applies to rigidbody2d which they are clearly using, not rigidbody)

yea i see it brought forth anew issue of during my first jump i only jump vertically and not in an angle as intended

not mine, im tyrna recreate the player controller of it tho

[final trellis]

probably a dumb question but how do i resolve this error? quick actions and refactoring isnt helping much

[slender nymph]

why are the constructors private?

[wintry quarry]

You have to invoke the parent constructor there if you want to do that

[final trellis]

forgor

[wintry quarry]

and the constructor will need to be at least protected to do that

AbilityCard(string cardName, Image cardGraphic, char identifier, int damate) : base(cardName, cardGraphic, identifier, damage) {}

[final trellis]

whats the protected keyword do?

[slender nymph]

it's like private, but inheriting classes have access too

private = only this object has access
protected = this object and inheriting objects have access
public = all objects have access
internal = only objects within this assembly have access

[wintry quarry]

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

Man I really wish we had access to the file modifier in Unity...

[final trellis]

this is like when science teachers tell you there are only 3 states of matter and then you find out later there are secret more evil ones

well i knew abt protected from college but the teacher never explains why things exist and only just what they are

[polar acorn]

But they were all of them deceived, for another state of matter was made

[swift crag]

wait until you find out about file

[warped jasper]

So guys whenever I put my script with the player movement and with animation, when I put the rigid body in, it doesn’t work like it it just straight up doesn’t work like the rigid rigid body just doesn’t work

[wintry quarry]

does it work though?

[warped jasper]

the animation works and the player movement works but the rigid body is like not there

[wintry quarry]

That doesn't make much sense

if you have a player movement script that works without a Rigidbody what's the Rigidbody for

Sounds like you're trying to mix multiple different forms of movement

that's a no-no

and it's not gonna work

[polar acorn]

In what way does it not work

[warped jasper]

like there’s no gravity on the player and the player can’t move

[polar acorn]

Does your animation affect the transform of the object

[wintry quarry]

You would need to show your code etc

[warped jasper]

no

[polar acorn]

If you disable the animator component, does it properly fall and get controlled

[warped jasper]

lemme check

yes

[polar acorn]

So then your animation affects the transform of the object

[warped jasper]

oh

[polar acorn]

You shouldn't be animating the object with the rigidbody. Your mesh should be a child object of that

That way it can be animated without affecting movement

[warped jasper]

thanks

[final trellis]

they shouldve called it privater

[wintry quarry]

Depending on the circumstances it could actually be less private than private

[swift crag]

we happen to be in a voice call together and i already pointed this out

owned

[wintry quarry]

Lol

[swift crag]

see also: publicer staticer, which means the value is stored on the internet

a pvp-enabled zone

[slender nymph]

where's the battle royale access modifier where objects have to fight over access to a member and only the last survivor can do so

[swift crag]

that's just the singleton pattern where objects destroy themselves

[polar acorn]

try {
  //access variable
} catch {
  Destroy(this);
}

[final trellis]

publicer jsut exposes it to the whole ass network

and then u got publicerererererer which gives the observable universe access

[last radish]

Im tryinh to make procedural wall generation for the backrooms, and stumpled accross this video(https://www.youtube.com/watch?v=wQj-l0vDQsA that describes how he generates walls. At around 3:13 he slightly explains it but i have no clue how to actually do it. Could someone help?

[inland sable]

hello

I have an error to send the raycast

It don't sow in editor mode

[polar acorn]

What's the error?

[daring crescent]

        if(Input.GetButtonDown("Jump"))
        {
            jumpPressed = true;
        }

        isGrounded = groundCheck();

        playerVelocity.x = moveDir * moveSpeed;
    }
    void FixedUpdate()
    {
        // Jump Logic
        if(jumpPressed && isGrounded)
        {
            rb2d.AddForce(Vector2.up * jumpHeight, ForceMode2D.Impulse);
            jumpPressed = false;
        }
        
        rb2d.linearVelocityX = playerVelocity.x;
    }

How could i write this easier without the if(Input.GetButtonDown)
I had jumpPressed = Input.GetButtonDown; before then i have huge input loss.
I need to press 10 times spacebar 😄

Someone can give me a hint how to handle Input in Update and AddForce in FixedUpdate?

[inland sable]

the drawray dont show

[polar acorn]

Is that line running?

[polar acorn]

Like that

That's how you'd do that

[daring crescent]

oh you mean as a one liner

[inland sable]

i dont know

[polar acorn]

Neither do I, since I do not have your computer in front of me.

[thorn holly]

Do a debug log to check

[inland sable]

now its go to up

[polar acorn]

Is the issue still the DrawRay not working? Because I didn't see you ever go check it in the scene view to see if it was visible

[cosmic dagger]

Dude went into outer space . . .

[verbal dome]

I assume you just need to adjust JumpForce then

[thorn holly]

It’s either a jump force issue or a jumping multiple times issue, from the looks of it. I’d do a debug log for the jump, see if it’s getting called many times or just once, if it’s many times something’s wrong with your ground detection, otherwise, your jump force is too high

[polar acorn]

the game is not running

[thorn holly]

You have to be running and in scene view

[inland sable]

i adjust the JumpForce to 5 and now is jumps, the ray dont show

[thorn holly]

Are you in scene view and the game is running?

[thorn holly]

Because here the game is running, but you are in the game view

[thorn holly]

And here you are in the scene view, but the game is not running

[inland sable]

Sorry, if it shows, but below where I want.

[polar acorn]

Then you probably want to start it somewhere above transform.position

[inland sable]

yes, in the center of the stickman

[polar acorn]

The first parameter of DrawRay is where you want it to start. Give it the location you actually want it to start at

[thorn holly]

Then draw the ray above transform.position instead of at transform.position

[inland sable]

and how i can do this (sorry I dont have a very level of english and programing on c#)

[thorn holly]

Did you make the code yourself or copy paste from somewhere else?

[inland sable]

I make my own code

using UnityEngine;

public class MoveStickman : MonoBehaviour
{
    public float Speed;
    public float JumpForce;
    public float DistanceToGround;
    private bool TouchGround;
    private Rigidbody2D rb;
    private Animator animator;
    private float horizontal;
    

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        animator = GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        horizontal = Input.GetAxisRaw("Horizontal");
        animator.SetBool("Walking", horizontal != 0.0f);

        if (horizontal < 0.0f) { 
            transform.localScale = new Vector3(-1.0f, 1.0f, 1.0f);
        } else if (horizontal > 0.0f) { 
            transform.localScale = new Vector3(1.0f, 1.0f, 1.0f) ;
        };

        Debug.DrawRay(transform.position, Vector2.down, Color.red);
        if (Physics2D.Raycast(transform.position, Vector2.down, DistanceToGround)) {
        TouchGround = true;
        } else {
        TouchGround = false;
        }
        if ((Input.GetKeyDown(KeyCode.W) || Input.GetKeyDown(KeyCode.Space)) && TouchGround) {
            Jump();
        };
    }


    private void Jump()
    {
        rb.AddForce(Vector2.up * JumpForce, ForceMode2D.Impulse);
    }
    // FixedUpdate is called at a fixed interval and is independent of frame rate
    private void FixedUpdate()
    {
        rb.linearVelocity = new Vector2(horizontal * Speed, rb.linearVelocity.y);
    }
}

it is

[thorn holly]

Add a Vector2 with some positive y value to the transform.position in the draw ray to raise it

[cold mist]

i know this is a weird question, but how do i make an object move almost towards the mouse?

and not exactly at the mouse position

[coral crater]

is it generally okay to check something that may be null? there's a possibility that prevPlace will be null at the point of checking. I assume that won't throw any errors, or is this problematic?

[grand snow]

yea you can compare null to something just fine

but you cant do null.foo() ofc

[slender nymph]

if it could possibly be null then you definitely should null check it before actually using it. however you probably should store the objects returned by those method calls in variables if you will need to use them again (like in the if statement)

[modest dust]

Define 'almost'

What are you trying to do

If you mean that you want to slightly offset the movement direction then get the proper direction vector and rotate it by however much you want

[coral crater]

thanks for da advice :)

[polar acorn]

Do you have a script named Image

[rich adder]

Check your namespaces

[honest iron]

no

[polar acorn]

Or are you importing a namespace that does?

[grand snow]

could be System image or something by accident instead of UnityEngine.UI

[rich adder]

hover over the Image class, if its not from UI namespace, then its wrong one

[polar acorn]

The .image shows that it's definitely the wrong class, Unity's Image doesn't have a property by that name

[slender nymph]

yeah seems like they may be using the UIElements.Image

[rich adder]

tru true. its just .sprite

[honest iron]

those are all the import i have

using TMPro;
using UnityEngine;
using UnityEngine.UIElements;

[slender nymph]

the last one is wrong

[rich adder]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.UI.Image.html

[honest iron]

import UI?

[slender nymph]

#💻┃code-beginner message

[honest iron]

UnityEngine.UI

OK

checking

ok, it worked

thank you:)

[swift crag]

note that a using directive lets you name something without fully qualifying it

it's not actually an "import" directive, where you have to include it to access something at all

using Foo.Bar;

...

var x = new Foo.Bar.Buz();
var y = new Buz();

it's just there for convenience's sake

without the using directive, I could still have written new Foo.Bar.Buz()

I just couldn't have written new Buz()

[drowsy helm]

Can anyone recommend a good resource for git patterns when working with another person? Right now we’re just sharing the asset dir without packages, but idk if that’ll scale well

[grand snow]

the unity project should be the root of the git repo (including Assets, ProjectSettings, Packages etc...)
You should use a good gitignore to leave out stuff not needed: https://github.com/github/gitignore/blob/main/Unity.gitignore

that will ignore things like the Library folder as that doesn't need to be comitted. If you leave out the other important folders your project will have serious issues...

[drowsy helm]

Ty!

[faint agate]

there is no for loop

[void dawn]

I need someone to teach me some stuff that i got stuck in my project

I don't want you to do it for me , I want you to teach me how to do it

You can dm me for more details but basically I need to add some stuff to my quake like fps game

1 voice line system , that works like duke nukem 3d were the character says a voice line depending on the situation

2 rigging enemies , I don't know why but I'm having a hard time adding animations to my enemies in the game , if you can help that would be great

3 gun movement, simple stuff I just want the gun to move when the player Walks and when the player shoots it

These are the main issues I'm having with the project right now , I would be very happy if you could help me

My dms are open

hello, ive adjusted the script to where its getting the current Selected Game Object, and vertical autoscrolling when at end. this script auto scrolls since im using keyboard to scroll. I dont want the auto scroll to happen on the last button going onto the next off screen but the button before the last one, so it starts auto scrolls on the one before last .
https://pastecode.io/s/5cszboon

ive been trying to make the current selected the one before the LastCheckedGameObject but cant figure it out

[swift crag]

i can't understand what you're talking about here

I dont want the auto scroll to happen on the last button going onto the next off screen

this in particular

is the problem that, when you switch from one menu to another, you see it smoothly scrolling back to the top of the second menu?

rather than snapping instantly to the top?

[main jackal]

is https://symbolserver.unity3d.com/ down for anyone else or just me

[faint agate]

Its a list of buttons and when I scroll one down from the final, the auto scroll happens. My goal is to have the auto scroll happen before going to the button off screen. I want the auto scroll to move or act when Im on 2nd to last button going onto the last, not when im on last going onto the button offscreen.

[swift crag]

Ah, so you need the scrolling to happen sooner

[honest iron]

Values is a list of enum values and i am trying to get a value by its name, tostring only return the type

public static SP getSPByName(string name)
{
foreach (SP i in Values)
if (name == i.ToString())
return i;
return null;
}

[rich ice]

temp variable names are cool and all but atleast keep them consistent

[rich ice]

is there an issue here? looks fine to me

[wintry quarry]

what is SP?

[honest iron]

its always return null, i.ToString() return the type of the enum ,i need the value name

short for SkillPower

[wintry quarry]

But what is it

an enum? A class? A struct?

also what is Values

we need more context

[honest iron]

gimme a moment i'll get it

[wintry quarry]

return null seems not correct if it's an enum

[swift crag]

consider Enum.GetName

[cosmic dagger]

They probably want GetName but there's a lot of missing pieces here . . .

[swift crag]

you give it an enum type and an enum value, and it tells you the relevant name

[thorn holly]

These are some pretty general concepts, I’d highly reccomend you learn how to do it yourself. Break it down into specific steps, do as many as you can, then google the ones you don’t know how to do or ask here

[swift crag]

(and allocates, iirc, yummy)

[honest iron]

public class SoulPowers
{
    public static readonly SoulPowers NONE = new SoulPowers(0, null, null, null, null);
    public static readonly SoulPowers Fire = new SoulPowers(1, Skills.FIRE_KNOWLEDGE, SoulPowersAttacks.FIRE_PHOENIX, SoulPowersAttacks.FIRE_RUSH, SoulPowersAttacks.FIRE_FIRE_BLAST);
    public static readonly SoulPowers Ice = new SoulPowers(2, Skills.ICE_KNOWLEDGE, SoulPowersAttacks.ICE_ICICLES, SoulPowersAttacks.ICE_ICE_STARS, SoulPowersAttacks.ICE_ICEBERG);

    public int SoulPowersID { get; }
    public Skills SoulPowersSkill { get; }
    public SoulPowersAttacks[] AttacksList { get; }

    private SoulPowers(int soulPowersID, Skills soulPowersSkill, SoulPowersAttacks attack1, SoulPowersAttacks attack2, SoulPowersAttacks attack3)
    {
        SoulPowersID = soulPowersID;
        SoulPowersSkill = soulPowersSkill;
        AttacksList = new SoulPowersAttacks[] { attack1, attack2, attack3 };
    }

 
public static IEnumerable<SoulPowers> Values
    {
        get
        {
            yield return NONE;
            yield return Fire;
            yield return Ice;
        }
    }

    public static SoulPowers getSoulPowerByName(string name)
    {
        foreach (SoulPowers sp in Values)
            if (name == sp.ToString())
                return sp;
        return null;
    }
}

[wintry quarry]

So it's a class

not an enum

if you want ToString() to do somethjing special, you need to implement it @honest iron

the default ToString for a class will just print the type

[honest iron]

need to use calss because c# not support that kind of enum,if only enum in c# was easier like java

[wintry quarry]

there is no need for a class

you can do this with extension methods

but either way

if you are using a class

you must implement ToString

or another function that returns the string you want

[swift crag]

I was a little confused by how ToString was somehow producing the type name

that explains it

[honest iron]

im used to do it in java

[wintry quarry]

ok, well now you're in C#

[honest iron]

i know

that is why im here

[nimble apex]

somehow my scroll rect cant scroll to the bottom, theres always one element that is "out of window" , like u can drag the scroll to see it, but it will bounce back again

[swift crag]

yeah, C# enums are very basic

Java enums let you do some funnier s tuff

[honest iron]

for sure

[polar acorn]

C# enums are ints with hats

[swift crag]

is there a ContentSizeFitter on the "Content" object?

if not, add one and then set it to control the vertical axis

(go for 'preferred' size)

[nimble apex]

nope 😭

[swift crag]

the Content object also needs a vertical layout group

set it to control child size and to not force expand children

[honest iron]

i think i'll just use switch for that

[swift crag]

together, these will:

• make the Content object request enough space to show all of the children
• resize the Content object based on how much space it wants

[nimble apex]

i got the layout group, but i havent added any of the fitter

[swift crag]

make sure you set it to control child size

Force Expand will make it do...interesting stuff

[nimble apex]

most of the UI i made dont really get to use that stuff tho

and i havent checked use child scale once

[swift crag]

That looks correct

[nimble apex]

ty 👍

yep it worked

[honest iron]

is there a way to get sprite from assets without making pulic varible in the script?

[rich ice]

why?

[honest iron]

i am trying to set image(sprite) and there is too many images to add them all

i wanted to make class just for that, class the holds all the sprites and i can just get whatever i need from it

[swift crag]

i suppose that, if you have a huge number of assets with predictable names, you could load them from a Resources folder.

but I'm unclear on why you'd want to do this, instead of just assigning the sprites directly where they're needed

[honest iron]

i have a image that can be changed to 1 from 8 options, if i could just get the sprite from the without add it from unity i could just add it to an enum the related to this image

here an exapmle of what im tying to do

 public static readonly SoulPowers Ice = new SoulPowers(XXXX,2);

playerSoulPowerImage.sprite = SoulPowers.ICON

[swift crag]

so, for example, you might have an 8-by-100 sprite sheet

100 unique "things"

and each one has one of eight types

[honest iron]

i dont think is what i ment

XXXX is where i want to add the sprite from the assets

[rich ice]

have you tried an array?

[honest iron]

yes , i wanted to make a class full of arraies just for the sprites, but i need the class to be static

so i need to remove MonoBehaviour

which leads to error ; 'ObjectsImagesList' is missing the class attribute 'ExtensionOfNativeClass'!

im also looking for a better name for the classs

[chrome garnet]

I have a character prefab that contains an Animator with an AnimationController attached. Multiple GameObjects are instantiated using that prefab. Does each instantiated GameObject get their own unique copy of the Animator and AnimatorController when instantiated?

I ask because when I invoke an animation through GameObject.GetComponent<Animator>().Play("...") on one of the objects, the animation is playing on all prefab objects.

https://paste.mod.gg/lojzipnsahyy/5

[eternal needle]

Yes each instantiated copy will have their own components. You can see it in the scene
Show the actual code. You're likely calling this code on every object

i still need help

how can i add sprites from unity

public static class ImagesClass
{
    public static Sprite[] Weapons = new Sprite[8];
    public static Sprite[] SoulPowers = new Sprite[5];
}

i've added the script to a gameobject

[rich adder]

why are they static?

[honest iron]

i want to reach the arries from everywhere in the project

[rich adder]

you don't need static here at all

use a singleton

[honest iron]

whats that

[chrome garnet]

https://refactoring.guru/design-patterns/singleton/csharp/example

[rich adder]

makes it so you can access an instance of a class from anywhere and ideally is the only instance
https://gamedevbeginner.com/singletons-in-unity-the-right-way/
https://unity.huh.how/references/singletons

most important can make the fields regular ones that can be used in unity inspector (drag n drop) references

[faint agate]

yes, sorry I was a little busy

[honest iron]

from what i read do far i don't think singletom will be much useful, it will be simple to just create a Instance of the class and make it static from my main clas

i might be wrong

still not expert with that

[rich adder]

if it wasn't useful I don't think I would've recommended it though

you can't have static variables and expect them to show up / be linked in the inspector

if you're only sharing the same asset list of images through specific classes / objects, you could also use a scriptable object too

You must've misread what singleton is then

[acoustic belfry]

hey, how i can make that i have to wait till an animation ends to do x thing. For example, when my enemy gets out of bullets, it has to reload, wich displays the reloading animation and then returns the bullets to it original amount. How i can archive the wait?

[rich adder]

couple of ways actually.
Animation event, or Animation state machine methods, or good ol polling the state w/ bool

[acoustic belfry]

wich one would be the most simple to understand?

[honest iron]

can you give me an example

[sonic hull]

use an animation event would be the simplest way

[acoustic belfry]

this is the script btw

    {
        if (balas > 0)
        {
            GameObject nuevoProyectil = Instantiate(proyectil, proyectilposition.position, Quaternion.identity);
            Vector3 direccion = (objetivo.position - proyectilposition.position).normalized;
            Rigidbody2D rb = nuevoProyectil.GetComponent<Rigidbody2D>();
            if (rb != null)
            {
                rb.linearVelocity = direccion * bulletspeed; // Ajusta la velocidad según sea necesario
            }

            balas--;
        }
        else
        {
            //Here its the reload thing
        }
    }```

[rich adder]

animation event is indeed the simplest, just has 1 major drawback is being aware of transitions could skip the key so pay attention to those

[rich adder]

sure one sec

[acoustic belfry]

what do you mean transitions?

i mean cuz its 2D, and every animation in the animator i have set all transition and stuff to 0

[rich adder]

also how many classes will be accessing these resources?

[honest iron]

1 sec

[rich adder]

yes I mean the animation transition between states

[acoustic belfry]

O H

[honest iron]

4 for now

might be more in the future

[acoustic belfry]

then how i do it, cuz i need to have the transition set to zero in the animator

or so i thought

[honest iron]

i didnt even added all the images

public class ImageClass : MonoBehaviour
{
public Sprite[] Weapons = new Sprite[8];
public Sprite[] SoulPowers = new Sprite[5];
}

there will be more

[sonic hull]

the meaning is that, for example, if your enemy's roloading aniamtion was interrupted by a hurt animation or other stuff, the reloading success event will never be triggered actually

[rich adder]

  public class ImageResources : MonoBehaviour
  {
      public  Sprite[] Weapons = new Sprite[8];
      public  Sprite[] SoulPowers = new Sprite[5];
      public static ImageResources Instance { get; private set; }
  }```

then do the Awake Instance assignment as shown in the links I snent
you can easily access
ImageResources .Instance.Weapons

[sonic hull]

and you need other game logic to help you with that, such as a repeat reloading mechanic or sth on the enemy ai

[acoustic belfry]

the idea was that the reloading overrider all kind of animation, but the idea of restarting the reload doesn't sound too bad

im pretty noob in the animation part btw, that's why i rather to let it zero, as i saw that works for 2D stuff

[sonic hull]

oki, it all depends on how you design it

[rich adder]

there is always this too
https://docs.unity3d.com/ScriptReference/StateMachineBehaviour.OnStateMachineExit.html
https://docs.unity3d.com/ScriptReference/StateMachineBehaviour.html

its not too complex

ok testing

[rich adder]

testing what?

[honest iron]

im testing if it works

[rich adder]

I didn't send the whole thing you still have to assign the Instance to itself
(#💻┃code-beginner message second link shows exactly how to write it)

it was example

I'm not here to write the entire thing for you lol

[acoustic belfry]

btw what u meant with the state w/ bool?

[rich adder]

well there is basically this
Animator.GetCurrentAnimatorStateInfo
which can check this https://docs.unity3d.com/2020.1/Documentation/ScriptReference/AnimatorStateInfo.IsName.html
so onceyou start a reloading coroutine or bool in update, you can wait the bool to become false again

[rustic stag]

Hello I was wondering if anyone can help me (or at least just explain to me) how to make it so you can deactivate certain game objects so its not able to be able to move when the camera isnt focused on it. I'm trying to make it so only one of my game objects moves/is able to be controlled by the player when the camera is focused on it. I have my code for my camera and code for each vehicle/player object if that would be helpful. (hopefully this makes sense)

[wintry quarry]

Just enable/disable the movement scripts as needed

When you "deselect" the object, disable its movement script.

When you select the object, enable it

[rich adder]

Animator anim;
bool reloadingAnimation;
bool reloading;
private void Update(){
    if(reloading){
        reloadingAnimation = anim.GetCurrentAnimatorStateInfo(0).IsName("reloadAnimState");
    }
}
IEnumerator Reloading(){
    //reloading
    while (reloadingAnimation)
    {
        yield return null;
    }
    reloading = false;
    //done reloading
}```
obv dont know ur full setup so  prob missed something but roughly

[acoustic belfry]

oh waos, thanks a lot!
o<o

[rich adder]

oh okay its just an example, don't just copy and paste it lol if you have questions ask them

there is obv still StartCoroutine missing and all that

you probably can do the entire thing in update but its late my brain aint brainin

[acoustic belfry]

ok xd i knew it i was just gonna analyze it, but thanks :3

But yeah...sorry if this sounds dumb, but how you entered into the IEnumerator?

[rich adder]

#💻┃code-beginner message

[acoustic belfry]

oh, ok

[rich adder]

you can easly call the coroutine when you start the reload process

if it needs to be in update put it behind a corutine variable or another bool

never StartCoroutine in update without those safety checks, aka start one every frame

[acoustic belfry]

i also have to play the animation, right?

[rich adder]

well yeah, the name of the state is what its looking for

[acoustic belfry]

i mean, add the script that activates it, the currentstateinfo will not do it for me

[acoustic belfry]

nice

[rustic stag]

This might sound like a silly question but how exactly would i do that. Is there a example of video unity has that might help me?

[faint agate]

I think the person who was about to help me went to sleep so im resending, ive adjusted the script to where its getting the current Selected Game Object, and vertical autoscrolling when at end. this script auto scrolls since im using keyboard to scroll. I dont want the auto scroll to happen on the last button going onto the next off screen but the button before the last one, so it starts auto scrolls on the one before last .
https://pastecode.io/s/5cszboon
Its a list of buttons and when I scroll one down from the final, the auto scroll happens. My goal is to have the auto scroll happen before going to the button off screen. I want the auto scroll to move or act when Im on 2nd to last button going onto the last, not when im on last going onto the button offscreen. basically I need the autoscroll to happen one button sooner

[rich adder]

currentStateInfo just checks which one of those gray boxes you're in. Aka the States in animator

[acoustic belfry]

got it

[wintry quarry]

What? Disable or enable a script?

You reference it and call .enabled = true or false on the reference

[honest iron]

i got it to work, thanks

[wintry quarry]

Sounds like maybe you need to just learn unity basics first?

!learn

[honest iron]

but im still curious why is it better than creating instance of the class?

[rustic stag]

Thank you. I know very little about unity (did one full lesson about basic movement/ camera movement) Thank you though!

[rich adder]

wdym creating instance of the class ?

putting the script on a gameobject literally IS the instance

[wintry quarry]

You are still creating one instance of the class.

[honest iron]

ImageResources sss = new ImageResources();

[rich adder]

thats poco way of creation yes

MonoBehaviours don't work like that

when put put MonoBehaviour script on gameobject that creates the instance

then you're just setting the current one you got on that object as the static variable to hold it

[acoustic belfry]

holup, just analyzing
This means when the enemy dries on bullets, it will make bool reloading true and in the same time StartCoroutine(Reload())?

???

{
    if (balas > 0)
        {
            GameObject nuevoProyectil = Instantiate(proyectil, proyectilposition.position, Quaternion.identity);
            Vector3 direccion = (objetivo.position - proyectilposition.position).normalized;
            Rigidbody2D rb = nuevoProyectil.GetComponent<Rigidbody2D>();
            if (rb != null)
            {
                rb.linearVelocity = direccion * bulletspeed; // Ajusta la velocidad según sea necesario
            }

            balas--;
        }
        else
        {
            animator.Play("Base Layer.MortemRifleReload");
            reload = true;
            StartCoroutine(Reload());
        }```

[rich adder]

is this in update you need a way to stop it from calling Reload coroutine every frame

[acoustic belfry]

no, its on it own

[rich adder]

what is on it own?

[acoustic belfry]

the state

its the state of shooting

[rich adder]

anyway just in case you can docs if(reload) return; animator.Play("Base Layer.MortemRifleReload"); reload = true; StartCoroutine(Reload());

just set it back to false in coroutine and ur golden

[acoustic belfry]

ooooooooooooooooooooooooooooooh, so i have only to make reload true. ok

Btw i have to paste this is update, right?

hey btw, this means for default, reload and reloadanimation are false, right?

[rich adder]

you already made reload true 🤔

[acoustic belfry]

no but i mean, Only that, not start the coroutine, cuz the reload if state its going to do that

[honest iron]

idk, i still need to get instance of the class whenever i want to use it, i was looking for a way to just get from it without instance(static)

[acoustic belfry]

what i mean is, i only have to do this in the shooting area

        {
            reload = true;
        }```

[rich adder]

ur literally getting the instance... its just stored in a static variable for easy access rather then grabbing the entire static class

[acoustic belfry]

...hey...
what diferences using booleans for ifes, and spawning methods?

[rich adder]

spawning entire voids?

[acoustic belfry]

for example, what diferences this

        {
            bullettimer -= Time.deltaTime;

            if (bullettimer <= 0)
            {
                bullettimer = firingspeed;
                disparar();
            }
        }```

[rich adder]

those are called functions / methods not voids
void is a return value for methods

[acoustic belfry]

from this

        {
            bullettimer -= Time.deltaTime;

            if (bullettimer <= 0)
            {
                bullettimer = firingspeed;
                disparar = true;
            }
        }```

and make it an if scenario instead of a method

[rich adder]

bool and method have different purposes

[acoustic belfry]

i mean, they work completely different...but their....purposes...mmm

[honest iron]

i mean yes, but..........

[rich adder]

the only common thing would be assigning values

[honest iron]

nvm i guess i'll leave it this way for now

thank you for helping me

[rich adder]

i dont understand the problem lol you aren't being clear

[honest iron]

sorry

[rich adder]

if its working why is not good

[honest iron]

OCD lol

[rich adder]

just want to make sure you know whats happening in that code and why yours wasn't fit for unity

[acoustic belfry]

let me rephrase it
what prevents me from making the shooting an if scenario instead of a method, and make the reload an method instead of an if scenario?

[honest iron]

im used for xxxx.ttt here is xxx.yyy.zzz

[rich adder]

nothing is preventing you, if you want to make it a method do so, you still need bools no matter what you choose

[honest iron]

yeah, im sill new to unity

[rich adder]

one belongs to the class itself, and one belongs to an Instance created from that class

[acoustic belfry]

with preventing i mean, with what consequences i would have
of course i can do it, but i wanna know what's optimal for scripting...its just sometimes i get anxious my scripts may be bad written ;-;

like, "i did x thing in the worst way possible"

like the informatic meme of the cow walking with it udders explaining my exact issue

[rich adder]

Unity cannot use Static variables in the inspector, nor can you put a static class on a gameobject, the only way you'd be able to assign those images is doing a Resources.Load fill or some other gameobject with serialized fields to pass those to static class.. At that point you mind as well skip the middle man gameoject and keep them on an actual gameobject that has component to serves them, since they can be easily linked in inspector this way

[normal turret]

What is the best way to tackle slope movement for a 2D game

Because in some games the character moves flawlessly on slopes but I'm having a lot of issues with that

[rich adder]

optimal script is a script that does the thing you want it to do . period lol

anything else is extra unnecessary worry

as long as you know..just dont make the code unreadable to you , and possibly others that you might need help from

[rich adder]

this is pretty vague

[acoustic belfry]

oh well, thanks :3

[normal turret]

Like moving at an angle or maybe not being able to move at a max-angle

Basic slope movements, I tried before and haven't got far...I'd love to get that out of the way soon

[rich adder]

was more talking about this

I'm having a lot of issues with that

what issues exactly? no one can help without knowing

[normal turret]

I have these slopes for example...I want my character to move on it without sliding or slowing down...

[rich adder]

ahh trig math here we goo

[normal turret]

I guess "slope-bounce" also is another problem with that

Because if I run down I guess my character doesn't stick to the surface

[normal turret]

Damn it, well I'm sin-ing off

Cosined by me

I could go on a tangent with this

[rich adder]

might want to raycast to get the slope angle then adjust your velocity / direction accordingly

[normal turret]

Should I keep the slope method seperate or can I do it all in the ground-check...?

Since I'm using tilesets, and it's all mostly one layer

[rich adder]

I haven't messed with Rigidbodies based controllers fully, but for CC I had it skipping slopes and thats what I did

[rich adder]

you're not looking for the gameobject / visuals

its just looks for colliders

[normal turret]

Oh ok nice, kind of like a ground check or wall check

[rich adder]

and their normal compared to Vup

[rich adder]

pretty much

[normal turret]

I just have to figure out the deal with slopes, I'll try working on that soon

[rich adder]

if you have raycast for ground, use the same ray
look for hit.normal

[acoustic belfry]

hey, this is not an issue i have, just an interesting thing i had in mind. Its a bad idea to mess with friction? i mean, i was thinking for make the always desired "m o m e n t u m", make that when i press a button to move the player, disable it friction, making it well, speed up in slopes and etc, and when the player releases the move buttons, for 2 seconds delays then it regains it friction. It may work, or bad idea?

[rich adder]

[acoustic belfry]

the issue is that for do my experiment, i practically have to make a whole new game, i just wanted to know if it was worth it

[rich adder]

just test it in a seperate project whats the big deal?

[acoustic belfry]

t i m e

but sure, its not a big big deal, it just that it was pretty xd

[rich adder]

I find it good to take a break from the same project once in a while

[acoustic belfry]

sounds fair

[rich adder]

tf. someone just spammed your tag and prob got yeeted lol

[faint agate]

seen u guys were helping someone else, thought id ask now but ive adjusted the script to where its getting the current Selected Game Object, and vertical autoscrolling when at end. this script auto scrolls since im using keyboard to scroll. I dont want the auto scroll to happen on the last button going onto the next off screen but the button before the last one, so it starts auto scrolls on the one before last .

I want the auto scroll to move or act when Im on 2nd to last button going onto the last, not when im on last going onto the button offscreen. basically I need the autoscroll to happen one button sooner

[honest iron]

since im not sure i have to ask

is its alright to give a single gameobject planty of scripts

[rich adder]

generally its okay as long as you don't mind the clutter

[honest iron]

like, player(gameobject) get scripts for movement, actions, attacks, inventory,skills, ect...

ok

tnx

[muted pawn]

wtf Im on mobile discord rn and I tried to send smth and my discord got fucked i tried closing it and it just spammed my message 100 times?!

sry for the spam tag on whoever it was, I thought I was gone forever 😭😭

probably a mobile user. there's a weird bug with mobile where messages get duplicated. the amount varies

[rich ice]

oh nvm, i probably should've read down a little more

[final trellis]

/*
if (card is a DamageCard)
{
    do stuff
}
*/

how would i do something like this?
card is an instance of the Card abstract class, and DamageCard inherets it

theres other card types that dont do damage, so i want to check to see if the card field contains a DamageCard

[wintry quarry]

Almost exactly like that

[final trellis]

wait is my psuedocode just like actually how you do it?? 😭

[rich adder]

just add a variable after DamageCard to do stuff with it
if (card is DamageCard damageCard)

[wintry quarry]

if (card is DamageCard dc) {
  Debug.Log("Damage amount is " + dc.Damage);
}```

[final trellis]

lmaoo

thats actually crazy 😭

[wintry quarry]

That being said it's... sort of an antipattern

Depending on the context

[final trellis]

wdym?

[wintry quarry]

Like, you should generally rely on polymorphism to get different behaviors from different subclasses

Abstract or virtual methods or properties. That sort of thing

[final trellis]

eh, thats prob fair but im makin a gamejam game so im tryna not spend too much time on certain things, ill keep that in mind tho when i do something that needs somethin like this in the future tho

I did this in the game I'm working on currently. BUT I am not using any built in physics for the controller.

it does give a very nice and responsive control

I stop adding friction when moving and add it when not

[thorn holly]

I mean there’s def some times I use it…for example my projectile collisions loop through all the hitboxes and check if they’re an instance of player/enemy base class depending on if it’s a friendly or enemy projectile

[sand heath]

How do they check

[thorn holly]

Oh I’m not using unity so it wouldn’t really apply

Actually that example I gave is really bad since unity handles collisions and you can get a reference to whatever you collided with

Though you’d still have to check if it’s an enemy so ig it still works

[sand heath]

ye and unity has tags and layers which would be much faster than comparing classes

[thorn holly]

That too

[sand heath]

the way you phrase it makes it sound like you're working with roblox ?

[thorn holly]

Java swing 😭

[sand heath]

squint

no clue what that is lmao

[thorn holly]

Its a Java library made for little pop ups like “enter your age” and such

Thought it’d be fun to make a game using it

It’s not

[stuck seal]

im about to put my head through a wall trying to implement the new action map, can anyone help me understand how im supposed to connect it to my character and c# script?

im following every tutorial and just getting nonstop errors, and even chatgpt has no idea whats going on

[thorn holly]

Makes stuff like this (except in my case obv)

[rich ice]

#🖱️┃input-system

[rich adder]

generate the C# class from the asset it will be the cleanest, or use Messages mode

[stuck seal]

i did, but then i go to implement it into vector2 movements and it says it cant find my input map

[sand heath]

show code@

[stuck seal]

i can just ask in input system though if theres a dedicated channel for that tho

i dont want to use the wrong place

[sand heath]

sounds like a code problem. your inputs are correct looking

either that or you forgot to put a player input component on the thing you're trying to control, but you wouldn't get errors without doing that.. I think

[rich adder]

player input component is unecessary if they generated the c# class

[stuck seal]

im doing some of this to connect it

can you explain more @nav ? then how am i supposed to implement it to my character controller? or is that even necessary?

[rich adder]

show the actual asset inspector

[rich adder]

thats not the asset

[stuck seal]

im sorry - im super new to this but im a coder by profession, so i just want to actually LEARN the code instead of downloading a controller

[wintry quarry]

That shit is from like 1996 and it's a UI library lol

[stuck seal]

i guess im confused what you mean by the asset

[rich adder]

thought you said you generated the class from it thats ..
click the input Actions where it says Input Action Asset, and select that

[thorn holly]

Exactly. Say you’re a hiring manager for idk Google and one of the applicants managed to make a full fledged game in Java swing without going mentally insane. That shows pure, raw, unfiltered determination.

[stuck seal]

you talking about this?

[rich adder]

thats the asset . yes. Also lets move it to #🖱️┃input-system

[thorn holly]

Plus when I go back to unity I’ll be so grateful for it being an actual game engine

[tropic smelt]

I don't know if this is the correct channel, but does anyone know why this character is in the scene and how to get rid of him?

[thorn holly]

If I had to guess, the player or one of its children is probably rendering in that sprite with a sprite renderer

[acoustic belfry]

Waos, looks cool

[honest iron]

is there a way to link gameobject to an Instance(class) from the script?

[wintry quarry]

Wdym by link

[thorn holly]

Like add the script to the game object as a component? Give the script a reference to the game object?

[honest iron]

lets say that i have 10 items (Instance) i want to give every gameobject one item, and if i click that gameobject i can use this item

[wintry quarry]

That's very vague

What does it mean to "give a GameObject an item"

Are you talking about attaching components?

[honest iron]

no

[wintry quarry]

Then it's very unclear what you mean

[honest iron]

let me find another way to explin

i have skills, i create gameobject for every skill, every skill has an Instance, when i press that skill i want to see more infomation from that Instance, but to do that i need to find the Instance that belong to the skill

[thorn holly]

What do you mean “instance”

[honest iron]

is there a way to add that Instance to the gameobject so i wont have to find it every time i want to

[sand heath]

it's very simple, I can share the code if you want for the controller though it's not something you can just copy and paste

[thorn holly]

Instance of a diff GameObject?

[honest iron]

List<Skill>[] Skills = new List<Skill>[5]; , Instance of skill

[thorn holly]

Okay so you have a list of the Skill base class

[wintry quarry]

It's weird/confusing to me that a skill would be a GameObject, to be perfeectly honest.

[honest iron]

im making a gameobject for every skill with the skill image

[sand heath]

ah so they are UI elements?

[honest iron]

the gameobject are, yes

[wintry quarry]

So these are not skills. These are UI elements representing the skills int he UI.

But the skills themselves would be something else, presumably.

[thorn holly]

Why can’t the subclass skill script just be a component of the ui element

[runic remnant]

Hello everyone, im new in C# and unity, and im just trying it out for fun, and to make games for hobbie, do you have any recomendation for a starting first game as begginer like me? (btw i can do 2d or 3d art, but ill prefered 2d) (sorry for interrupting just like that)
