hey guys
i am stuck in a bug for around two or three weeks
i can't wall jump after another wall jump
here you can see that i can't jump after colliding with the other wall
idk why

Strange! Maybe double check if you have any unused using statements, I would expect code stripping to strip out parts you don't use. Or set it to high ( Project Settings --> Player --> Optimization). See image for reference. If this doens't help I would suggest #🌐┃web

Guys i need help fixing this bug:

What I'm trying to do in details:
So i made the script Ball_mover which moves the ball directly towards the player, and it did work well at first without any bugs but later on when i add physics to the ball (aka Rigidbody) it started bugging

Anyhow to fix that?

low warren
slender nymph
#

okay so what debugging have you done? or are you just saying that you've just tried random shit and expected to find a fix?

void notch
low warren
low warren

#

There's a lot to debug. Check if all the booleans are correct in the first place. But I would suggest just re-write it a bit simpler so you understand it again.

low warren
#

or no?

void notch
#

There's code that says: canWallJump = false in your wallJump() method. So very likely that has something to do with it.

low warren
#

nevermind let me try it

void notch
#

If you always want to wall jump, just remove the boolean canWallJump 😄

cloud walrus
slender nymph
#

you need to show code if you want help with your code

eternal needle
cloud walrus
#

okay here's my code

using UnityEngine.UIElements;

public class Ball_Mover : MonoBehaviour
{
    [SerializeField] Transform player;
    [SerializeField] float moveSpeed = 1f;
    Vector3 playerPosition;
    void Start()
    {
        playerPosition = player.transform.position;
    }

    // Update is called once per frame
    void Update()
    {
        transform.position = Vector3.MoveTowards(transform.position, playerPosition, Time.deltaTime*moveSpeed);
    }
}```
slender nymph
#

yeah, it also appears that everything by the Y for both position and rotation is constrained on the rigidbody

cloud walrus
slender nymph
eternal needle
#

if you want physics, you have to move via physics too. Use the rigidbody and AddForce in the direction that you want

cloud walrus
slender nymph
#

that is when physics is updated

steady flame
#

wow thats a lot of information

cloud walrus
low warren
#

okay i found a thing
when I'm colliding with the other wall
IF I press the arrow key of that direction(left OR right) the player WILL jump

eternal needle

set a varible to accest you rigid body, and access it velocity in your code witha vector3

#

ive downloaded a movement script on unity from 2019 that comes with an example player prefab, but when i use the prefab it just falls through any objects i put it on top of and the controls dont work, or if i put the movement script on an object with a rigidbody, it just floats while still not being controlable, my input keys seem to be correct, im not sure what i need to do to get this to work

slender nymph
#

perhaps check the asset's documentation to see what setup is required to make it work

limber flower
#

all it has is a readme that says you can either use the prefab or use put the movement script on an object to do the camera control yourself

#

i checked the issues tab on github and none of the solves for similar issues worked for me

slender nymph
#

then either link it so someone can look at it since nobody here is psychic so we cannot possibly know what you're using or what its requirements are or post an issue on the github or anywhere else the asset author accepts support requests

limber flower
#

heres the github

slender nymph
#

are the objects that you put the prefab above on the default layer or are they on a different layer?

limber flower
#

all of the objects in the parent prefab are on default

#

and the objects below yes

slender nymph
#

i did not ask about the objects in the prefab

limber flower
#

yeah i misinterperated it but everything is on the default layer'

slender nymph
#

then you probably need to look at the layer mask on SurfPhysics to make sure it isn't set to None or something

#

otherwise you should be asking the asset author for help

limber flower
#

ill put an issue request

#

When is an Abstract class useful in c# nowadays? I previously thought they were useful for standard implementation but you can do that with interfaces, so any methods without implementation are just the same as "abstract" methods in an abstract class right?

#

Are they only good for having inheritable variables?

slender nymph
#

depending on your needs an abstract class can possibly be interchanged with an interface instead, but abstract classes are strictly for inheritance and can contain variables as well as properties and methods, can have non-virtual/non-abstract methods that contain behavior.
interfaces can only define properties and methods, and while you technically can add default behavior to an interface method in most cases you really shouldn't

wintry dew
#

i see so its just better practice to not use interfaces for "is-a" relationships

#

and overall more troublesome

hi just coded smth for a bullet that makes it move torwards the player

image.png
#

and flip the sprite depending on its x velocity

#

but is there a way for me to just make it point straight at the player?

#

i know the vector pointing to the player im just not sure how to turn that into a direction for the gameobject

humble marsh
#

Quaternion.Lookrotation to get a rotation, transform.lookat(playerpos) to make it just look at player

obtuse ether
#

teal viper
#

That would probably make it look on the z axis, which is not what you want in 2d.

obtuse ether
obtuse ether
#

im now trying to figure out how to fix that

teal viper
#

That's not gonna work. You could keep the bullet sprite orientation with it's x axis and assign the direction to transform.right

#

Actually, nevermind that. It might flip the sprite to the back face.

#

You could keep flipping the sprite and assign the transform.right toPlayerDir or -toPlayerDit depending on the flip state.

LookAt should work, no? Just use z as world up

hey guys, im working on a 2D game for a project, and i wanna add an ability where the character shoots and when the bullet collides, the character transform position = collision transform position. However this only works when the prefab is added to the hierarchy, and not when i instantiate the bullet. Can someone help me with this

calm shoal
ocean loom
versed light
slate roost
#

and that seems to work ok, gonna do some playtesting with it

versed light
#

then just add a 0.0001f epsilon to skin width

#

eg
velocity.y <= Mathf.Abs(velocity.y) + skinWidth + 0.0001f

slate roost
#

I'll try that, that seems less messy than what I did

versed light
#

the <= should not always be false due to imprecision issues though

calm shoal
# ocean loom

ok so it was the installer it gave me, which one do i choose there is a bunch

versed light
#

usually imprecision issues is for == more so than <=

#

unless you're dealing with very small velocities and skin widths

specifically the first one, yes. because that also links to the second but also the first one has troubleshooting instructions for if it is still not working after completing the typical setup steps

so fucking read them

if that doesnt work read it again

step 1 for you should apparently be "learn to read"

you do realize that your screenshot earlier proved you didn't even do step 1 there, right?

Did you regenerate project files? Via unity? Did you regenerate project files via VS?

im not going to reinstall

You don't need to reinstall. If it's installed already just take a screenshot

Hey there, I was wondering how one might go about rotating this "beak" object around the beakPivot parent? Currently it's rotating fine, but I haven't managed to get it to rotate as a pivot to the parent if that makes sense. If you need me to elaborate on anything further just lemme know, thanks!

If you have compiler errors, if possible comment out those files so Unity can compile code.
Ensure the Visual Studio Editor package is installed and updated in UPM (com.unity.ide.visualstudio).
Regenerate project files via Unity.
Close VS.
Select regenerate project files in EditPreferencesExternal Tools.
Reopen VS via AssetsOpen C# Project.
Regenerate project files via VS.
If an assembly in the Solution Explorer is marked as (incompatible), right-click it and select reload with dependencies.
Restart your computer.

makes no sense

didnt think it applies to me

pleaase dont say such stupid things, you were specifically instructed to follow ALL the Steps

#

if you here to just troll find another server..

worn spade
#

yeah bro im having the time of my life trolling rn

#

it would be lot less frustrating to you and everyone involved if you actually learned how to follow a step by step instruction without claiming "it doesnt apply to you" when its part of Troubleshooting

#

make a video if you must

congrats, it is configured after that

if only you'd followed the instructions earlier when i told you to you would have been done a long time ago

rich adder
# worn spade

ya you didnt check solution explorer again after you did that..

#

but is configured

slender nymph
#

i don't even understand how they thought that step didn't apply to them since it was clear from their earlier screenshot that the project was marked (Incompatible) and that is like the main thing mentioned for that specific troubleshooting step

so i was actually able to get chatgpt to do it for me partially sadly it still wont be endless but it should be basically endless because unless someone finds a way to edit the save data no one will get enough money to get more then it has rn

but my issue im having is the way it rounds up and stuff so i have it once it starts using abreiveations to display for example 9.8K but it displays that when your at 9750 so i dont think that is the right aproach since it will not give the most acurate numbers

#

got any ideas

#

should i add another number at the end so it would be 9.87k or change it to only switch to 9.8K when it reaches 9800

Super quick question, how come when creating a new rigidbody variable, you have to specify that "rb" is getting the rigid body component when you've already specified "Rigidbody rb;" at the top??

you should really look into c# basics then first and follow an actual tutorial, plus do examples to wrap your head around it

rich adder

null is default for reference types
if you want more understanding , look up Reference Types vs Value Types

saying "Rigidbody rb;" doesnt assign the component to rb, it just tells unity that thats where the variable is being stored??

# cosmic gorge okay that makes a lot more sense now thank you

if u wanna distinguish null and 0 quick , heres the rule , 0 is something and null means nothing

0 is a number right? no matter how u understand it, it is a number/value, so its related to number types, lets say int(eger), or float, or double, yeah it can also be a char/string , but u need to know it is a value, it is NOT nothing

0 or 0.0f is the default value of number types , because of special reasons, in C# those simple types cannot be nulled, they must always have a value , so if u dont do anything to integers/floats, they will still get a 0 , and it means they have a value

as for reference types, like those rigidbody, they dont need to have something at first, they can be empty, because u can "reference nothing" and C# allows it

#

u will get null reference tho if u try to use the value 💩

rich adder
#

well string is reference type
(basically an array of chars)

nimble apex
#

string is quite special here, because C# allows string to have nothing

#

oh that make up the whole thing lol

rich adder
#

but yeah they have value semantics
aka they are immutable, can be compared by value with ==

eternal needle
#

i would really avoid just dumping information like this, to just let them learn from an actual resource. Even just bringing up int? to say we can ignore it is going to confuse them more. Plus I don't think char[]{0}; is even valid syntax

#

Ive never really seen these kind of teachings benefit the person more than just letting them go and learn properly. Strings werent even the topic of discussion

im trying to make a 2.5D Platformer but my jump button doesnt work when i play the game on my phone but when i try it in the phone simulator on my pc it works. The right and left movement works on my phone as well just the jump button doesnt. The problem doesnt occur because of the onGround variable not being true, I tried removing the onGround variable from the jump if statement and it still only works in the simulator not on a real mobile device. It may have something to do with the way I made the jump button I just put an image on the canvas and gave it a touch button component and mapped it to the south gamepad button and in the input system manager I added the south gamepad button to the jump action is there maybe something wrong with doing it that way or is there a better way to do it? https://paste.mod.gg/basic/viewer/cbeznexattvf/0

could someone explain to me, why this throws error The non-generic type 'Queue' cannot be used with type arguments?

#

it's not possible to return a Queue of ICommands?

hi, need some help, i am using a function for player movement that addforce , i want to keep the momentum and velocity constant, what is the library function in unity for that

young pewter
#

hey guys, I am having trouble using the new input system
basically, I can't make a click action work
this is my script:

# 
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;

public class MeleeAttack : MonoBehaviour
{
    [Header("References")]
    public Animator animator;
    public InputActionReference fire;

    [Header("Parameters")]
    public int numberOfAttacks;
    public float cooldown;

    private float timer = 0f;
    private float cooldownTime = 0f;
    private int attack = 0;


    private void OnEnable() 
    {
        Debug.Log("enabled");
        fire.action.started += PerformAttack;
    }

    private void OnDisable() 
    {
        fire.action.started -= PerformAttack;
    }

    private void PerformAttack(InputAction.CallbackContext obj) 
    {
        Debug.Log("Cooldown = "+cooldownTime + " timer = "+timer+" attack = "+attack);
        if (timer > cooldownTime) {
            if (attack >= 3) {
                cooldownTime = timer + 2 * cooldown;
                attack = 0; 
            } else {
                attack++;
                cooldownTime = timer + cooldown;
            }

            animator.SetInteger("Attack", attack);
        }
    }

    
    void Update()
    {
        timer += Time.deltaTime;
    }
}
#

these are the settings

#

what am I doing wrong?

#

It is not calling the perform attack function (the debug is not appearing on console)

timber tide
#

may need to call fire.enable. I forget

Was just gonna say the same

protected override void EnableInputs()
{
    click.Enable();
}

protected override void RegisterActions(bool register)
{
    click.performed -= Click;

    if (register == false) { return; }

    click.performed += Click;
}

how can i make a button do 1 thing when i just click it once and do another thing when i hold click on it for like more then a second

#

(i need a button to do 2 things for a mobile game so i cant just do right click)

hexed terrace
#

Off the top of my head, I can't remember if they work with touch though.. so, test

amber spruce
#

public void OnPointerDown()
{
isHolding = true;
holdTimer = 0f;
}

public void OnPointerUp()
{
if (holdTimer < holdTime)
{
StartCooking(); // If released quickly, cook instead
}
isHolding = false;
}
so like this?

hexed terrace
#

No

#

Nothing (other than two vars being set) will happen while it is down, and start when you release

#

The below informs you how to share !code correctly

eternal falconBOT
amber spruce
#

ooohh it was 3 of those things i thought it was 2 i was super confused lol thanks

hexed terrace
#

Click will happen every time, unless you put in some check if you don't want it too

amber spruce
#

Also is there a better way of doing what I’m trying to do because I have a button that i need to click to start it but also click to open upgrade menu

#

Would it be better to add another button above it to open the upgrade menu

hexed terrace
#

With that amount of info.. I'd say yes

raw fiber
#

How do i make that the button needs to be played to the end and only then can get played again?

#

You have two options:

  1. Don't use PlayOneShot but instead assign the buttonClip to the audioSource directly and .Play() it. That will let you check if the audioSource isPlaying in your PlaySound() function's if statement.

  2. If you want to use PlayOneShot, then you need to also have a bool IsSoundPlaying that is set to true when you play the sound, and then set back to false by using something like a coroutine that waits the length of the AudioClip buttonClip

whats the problem and where can i set it to single or smthing

make sure all packages are up to date, if the error persists after updating packages then close unity, delete the Library folder from within your project, and open unity again so it regenerates the Library folder (this will also cause a full reimport of all your assets)

Hi, the (Lightbulp) Quick actions and refractories is not working for me. It's the very first time I'm scripting.
After I write "update" then press Tab on the keyboard, it should automatically write "private void update()"
But it just goes a few spaces forward instead. I tried CTRL+. and by right clicking it, nothing happened. The lightbulp is also not showing on the left side.

Hey y'all, having some trouble atm with my coding. Currently, I want to have a random chance to have a special card pop up so the player can play it. However, this would have to be in a specific area and I don't really know how to do that. (Can y'all tell Im a beginner beginner?) Anyway lol, here's my code.
https://paste.ofcode.org/32QSFc2xZbGYFHuZwgUDziw
What I basically want is the clones of these cards (which have the buttons to do stuff attached to them) to pop up, with a random chance to be any one of them.

How would yall go about it? I cant really find any good videos to watch on going about this. Thanks. (Please @ me if you respond, thank you so much!!!)

produces these logs:

  • Button added for: Card_Air Boost

  • Button still there? True

  • Number of listerners Card_Air Boost: 0

  • Button still there? True

What am i doing wrong?

GetPersistentEventCount() does not count listeners added via AddListener. a PersistentListener is one added via the inspector

So this should produce a log, right?

slender nymph
#

when the button is clicked, yes

dusky pike
slender nymph
#

have you confirmed that the button actually works?

dusky pike
grand snow
#

im gonna guess its not sized or positioned correctly to ACTUALLY be clickable

dusky pike
#

(The Button image is the black thing)

slender nymph
#

click the event system and check it's preview window when you try to click the button (click the button multiple times to be sure since clicking out of the game view makes it lose focus so the first click in it again will be the one to give focus back)

Ahh, i found my Problem... I am building the Card Objects here:


    private void Start()
    {
        _getUnits = FindObjectOfType<GetUnits>();
        _getUnitDecks = FindObjectOfType<GetUnitDecks>();
        _getCardObjects = FindObjectOfType<GetCardObjects>();
        
        // Lade alle Karten:
        allCards = _getCardObjects.Load(cardPrefab , cardButtonPrefab);
        
        // Lade alle Units und ihre Decks:
        allUnits = _getUnits.Load();
        
        // Lade die Decks der Units:
        unitDecks = _getUnitDecks.Load(allUnits);
        
        // Sorge dafür das Units im Dropdown auswählbar sind:
        PopulateUnitDropdown();
        
        // Event-Listener hinzufügen:
        unitDropdown.onValueChanged.AddListener(OnUnitSelected);
        
        // Alle verfügbaren Einheiten:
        PopulateAllCardScrollView();
    }

(In the line: allCards = _getCardObjects.Load(cardPrefab , cardButtonPrefab);)

And "clone" theme here:

# 


    private void PopulateAllCardScrollView()
    {
        // 1. Vorherige Karten aus der Anzeige entfernen
        foreach (Transform child in cardScrollViewContent)
        {
            Destroy(child.gameObject);
        }

        // 2. Falls keine Karten geladen wurden, Debug-Warnung ausgeben
        if (allCards == null || allCards.Count == 0)
        {
            Debug.LogWarning(":warning: Keine Karten zum Anzeigen gefunden.");
            return;
        }

        // 3. Alle geladenen Karten im cardScrollViewContent platzieren
        foreach (GameObject card in allCards)
        {
            GameObject cardItem = Instantiate(card, cardScrollViewContent);

            // Optional: Name für Debugging setzen
            cardItem.name = "Card_" + card.name;
        }
    }
#

That somehow removes the button Click component... how do I clone an Object with an working Button?

not gonna lie i cannot understand this code

make sure you dont modify your prefab

Okay, when im loading my scene I wanna load all Cards that exist.

Those are stored here: (Normaly not part of the UI)

When i use a Filter or smth, i wanna scan all the cards there and only use "some cards"

this Code:


    private void PopulateAllCardScrollView()
    {
        // 1. Vorherige Karten aus der Anzeige entfernen
        foreach (Transform child in cardScrollViewContent)
        {
            Destroy(child.gameObject);
        }

        // 2. Falls keine Karten geladen wurden, Debug-Warnung ausgeben
        if (allCards == null || allCards.Count == 0)
        {
            Debug.LogWarning("⚠️ Keine Karten zum Anzeigen gefunden.");
            return;
        }

        // 3. Alle geladenen Karten im cardScrollViewContent platzieren
        foreach (GameObject card in allCards)
        {
            GameObject cardItem = Instantiate(card, cardScrollViewContent);

            // Optional: Name für Debugging setzen
            cardItem.name = "Card_" + card.name;
        }
    }
  1. Clears all Child Objects in the UI content container here:

dusky pike
#

Let me write it out

dusky pike
# grand snow I will help if you can correctly describe the problem but it helps no one if you...

My first Problem:

  • Im adding a listener manually per Code, but it didnt show up
  • Fixed (its just not visible in the inspector, sry i didnt knew that)

My second Problem:

  • im generating (UI) CardObjects from a json. These Objects get the mentionend listener.
  • I store them outside the UI Canvas (i know that doesnt make sense and I will defenitly change that later)
  • I use this TEMPORARY Code snippet:

    private void PopulateAllCardScrollView()
    {
        foreach (GameObject card in allCards)
        {
            GameObject cardItem = Instantiate(card, cardScrollViewContent);
        }
    }
  • To copy them into the UI Canvas.
    The Problem:

The copying seems to delete the Button component.

# 
s    

private void Start()
    {
        // _getUnits = FindObjectOfType<GetUnits>();
        // _getUnitDecks = FindObjectOfType<GetUnitDecks>();
        _getCardObjects = FindObjectOfType<GetCardObjects>();
        
        // Lade alle Karten:
        allCards = _getCardObjects.Load(cardPrefab , cardButtonPrefab);
        
        // Lade alle Units und ihre Decks:
        // allUnits = _getUnits.Load();
        
        // Lade die Decks der Units:
        // unitDecks = _getUnitDecks.Load(allUnits);
        
        // Sorge dafür das Units im Dropdown auswählbar sind:
        // PopulateUnitDropdown();
        
        // Event-Listener hinzufügen:
        // unitDropdown.onValueChanged.AddListener(OnUnitSelected);
        
        // Alle verfügbaren Einheiten:
        PopulateAllCardScrollView();
    }

#

sorry but this doesnt even make sense what you're saying: The copying seems to delete the Button component.

dusky pike
rare basin
#

i dont actually

#

is the Button component removed from the spawned instance?

#

or what

dusky pike
#

No, the Connection between the Function


    private void OnButtonClick()
    {
        Debug.Log($"Button auf der Karte {this.name} wurde geklickt!");
    }

and the button is lost

dusky pike
rare basin
#

listeners?

#

unless you've added some listeners to the onClick in the prefab

#

you never add them in code after you create new instance

#

but since it's a private function, then you didn't add it via inspector

#

so you just need to add the listeners to the spawned instances

dusky pike
#

yeah i know

dusky pike
rare basin
#

it's not random at all, it's all explained in the docs

dusky pike
#

Thats fair

grand snow
# dusky pike I just dont know random stuff like that

Unity could technically copy the whole managed object (c# stuff) state (so other variables) but that could quickly cause problems.
So as long as you remember that serialized stuff gets copied and the rest is back to "default" you will be fine

Say I have two lists, one is {15, 25, 10, 50} and the other is {a, b, c, d} I want to order the first list in ascending value so it would be {10, 15, 25, 50} and I want the second list to match that reordering {c, a, b, d} How do I do this?

#

but why does it use two lists instead of a single list of some data structure

ember tangle
#

thats a great question

#

This may be boneheaded but how do I access specific values in a multiple item list like List<(int, char)> foo

#

if I wanted only the int

rare basin
#

why cant you just make a struct/class

#

and make List<ThatStruct>

#

or w/e

ember tangle
#

scriptable object is needed

rare basin
#

ok and what about it

#

you can make List<YourStruct> in scriptable object

grand snow
rare basin
#

or serizeable class

# 
public struct MatchingIntChar
{
  public int myInt;
  public char myChar;
}

public List<MatchingIntChar> foo;
#

why do you really want to keep it separated in 2 lists

#

when you need it combined/matching

ember tangle
#

Its not a well informed decision, its just what I did to make it work. Its for a spawn table for various things.

#

Now that I need to order the one list by the other im looking for solutions

rare basin
#

just make the int/char inside 1 class/struct

yea its not hard. we sort the list using a value we can easily compare in the type.

ember tangle
#

thanks for the help!

#

If only this worked ```public struct SpawnChance<T>
{
public T type;
public int chance;
}

[CreateAssetMenu(fileName = "SpawnTable", menuName = "Scriptable Objects/SpawnTable")]
public class SpawnTable<T> : ScriptableObject
{
public List<SpawnChance<T>> spawnChances;
}```

#

I'm realizing the solutions that were offered wont work because the way I implemented the spawner requires two lists newDoodad = GameObject.Instantiate(Spawner<GameObject>.RollType(levelSettings.doodadSpawnTable.chance, levelSettings.doodadSpawnTable.prefabs)); because of the generic type.

ember tangle
#

I feel like at that point its the same as my current setup of having every spawn table being its own scriptable object of two lists.

#

but I could be wrong.

slender nymph
#

i mean, there would still be just a single list so you aren't attempting to sort one list then rearrange the other to match the new order of the first list

Hey would anyone know how to prevent the player from sliding down on edges of platform like this?

I want to keep the capsule collider because I like how it interacts with all other aspects of my game but this small issue caused by the shape of the collider is getting in the way.

Hmm you could blend in a box collider when you stop moving

#

It's also possible to make a "rounded box" using boxes and a couple of capsules or circles

rich adder
#

hell you can even make the bottom a skinny rectangle

eternal aspen
verbal dome
#

You should enable continuous collision detection on the rigidbody too

#

To avoid most clipping issues

frosty hound
#

Using a flat bottom collider will cause issues when moving on seams, and other places like walking up ramps. You can consider shrinking the collider when detecting it's over "air" (raycast), and then gradually increasing it back to its former size, this would let the player fall expectedly, and then also push them away from the wall if they try to go against it.

Alternatively, you could also add force upwards to keep the player afloat, by the offset that is the bottom of the collider and the contact point?

Hello! I've got a PlayerController, and in this I've got my basic movement stuff like inputs, locomotion etc. I've also added swimming. Now, because it was possible for my character to keep jumping while holding spacebar, I added a coyote timer and jump buffer. Which then in turn caused my character to jump endlessly when jumping out of the water. Except, now my character cannot jump out of the water.

I was hoping that anybody could have a look into the code and advice me on how to solve this issue.

I've put all relevant code in the pastebin with descriptions.

#

make sure its resetting properly when exiting water

#

could possibly add a cooldown before allowing jumps after leaving the water

#

controller code is alot for someone to have to sift thru to find ur issue.. i'd suggest to do what i just mentioned.. debug those values.. find more specific of a problem and return if u can't solve it

#

^ def should consider some sort of state-machine type pattern if ur getting into so many conditionals

#

i'd suggest a basic Enum state machine to start w/

#

break up ur code into states and use a switch statement to run each logic block respectively

bright osprey
#

it helps break down the responsibilities of your code into manageable chunks. You can also handle transitional moments easily with an OnEnter and OnExit method for each state

#

Interfaces will help this functionality if you fancy the above behaviour. Otherwise any state machine will be a helpful refactor

outer haven
#

That makes sense, it does sound a lot more managable than having everything in one huge chunk.

    enum PlayerState { Idle, Walking, Jumping, Swimming }

Well. I've tried asking chat GPT to help me with converting everything to a state design pattern because I wasn't sure how to go about it. And it looks awefully complicated for the movement I'm going for, so it doesn't look like it's worth it. It would basically be starting from scratch all over again and throwing a week worth of work in the gutter. 😦 @rocky canyon @bright osprey

rough lynx
#

If your current design works I wouldn't sweat it

No worries! i didnt mean to tell you to throw all your work away 😂 might be worth creating a small side project and following a state pattern tutorial? if you want to take a break from the project 🙂

ChatGPT will give you one of these:

  • a somewhat good answer, if the request is simple
  • a bad answer that works
  • a horrible answer that doesn't work
  • way too complicated of an answer that may or may not work
rocky canyon
#

the problem with chatgpt is over-reliance..

keen cargo
#

That too

rocky canyon
#

not really it's fault.. but if it makes a mistake.. it needs u to point it out to it

#

b4 it runs off on a tangent

rough lynx
#

Never really understood the appeal of state machines for stuff like character controllers. It just seems like you're intentionally impeding yourself but maybe I'm just being shortsighted

#

Why limit yourself to very specific states

rocky canyon
#

a good statemachine is scaleable

#

and u can add states.. EASIER

#

than w/o one

keen cargo
#

State machines have their place and time, if there's a lot of states to work with then it's absolutely useful

rocky canyon
#

if u dont have a statemachine.. if u go and add functionallity.. u need to go and add it EVERYWHERE in the script..

#

if u have a good statemachine.. u could add it w/o worrying.. b/c the rest of the class could care less if that state is there or not..

outer haven
# keen cargo ChatGPT will give you one of these: - a somewhat good answer, if the request is ...

I've used chatGPT to debug in the past for this code. But I learnt to back up my code a lot because it often sends me around in circles. That's what's happening right now with the code I got too.. because the code itself works right now, except the ability to jump out of water. Because I've got a jumpbuffertimer and coyotetimer and I've had to switch the way the game handles spacebar presses while swimming.

its mostly to refactor.. and to write boilerplate code now-a-days

#

but if ur smart about it.. its just a tool like anything else

outer haven
#

I know the basics of C# so far, I've also done some stuff in Python. But these scripts for my game are my first time writing scripts that are this big.

rocky canyon
#

went from 1500 lines of code or so down to 7-800 after a few refactors..

#

ever heard of the SOLID principles?

outer haven
#

I haven't before, no 😮

rocky canyon
#

heres a few sources.. the reason i ask b/c the first one.. and probably the most important for beginners is.
Single Responsibility

#

you want ur classes to stick to doing (1) thing.. thats MY job
if ur classes are doing more than (1) thing.. or are referencing many different scripts/systems..
it may be too much for a single class

outer haven
#

That actually makes sense. I feel like the current script actually has a few things scattered around a bit too much.

rocky canyon
#

if u keep it in ur mind while u code.. its a bit easier..

#

like here.. you can see that i have many different components all technically on my character controller..

#

each one doing its own thing... that way i don't have to worry about every little mechanic I have falling apart say i accidently break (1) or more of the other scripts

#

Composition is what its called i believe.. (when u have multiple classes on a single object)
each doing a single thing.. but together adding up to the total functionallity

i typically use an Image component.. stretched to fill the canvas

I did the same as you showed way before

#

the problem is, it works for other UI

#

but not for other raycasts

noble forum
rocky canyon
#

not sure what that is..

  • you can scale it and position it however u want *
#

if u need it to block some things and not other things.. then change the sorting layer where its above the things u want to block and below the things u dont

but i can still click on chesspieces and cards

do u just need certain things to not be interactable?

noble forum

It is preview of the card

#

when active, i want nothing else to be interactable, besides few things that are children

fastest way to do so is to block raycasts

Also for some reason i heard that using things like public CardWrapper cardWrapper all over the code isnt good. Why?

its better to have hands-on with the code and know its blocking it

than just hope something will do it

rocky canyon
#

ive seen both sides of the argument tho.. (no clue why or whats better)

rich adder
rocky canyon
#

I've used classes as tags/layers...

if (Physics.Raycast(ray, out hit) && hit.collider.TryGetComponent(out MyInteractable interactable))
{
    Debug.Log($"Hit interactable: {hit.collider.gameObject.name}");
}```
with `MyInteractable.cs` being just an empty class i attach to gameobjects.
im not 💯 sure thats the same thing tho

Hey guys, having a problem when switching scenes with cinemachine.
Having three scenes

1. Systems (Persistent with MainCamera and Cinemachine Brain)
2. MainMenu (3 Cinemachine Cameras)
3. Gameplay (1 Cinemachine Camera)

Starting with Systems and MainMenu, everything works fine and I can transition between all 3 Cams.
Loading Gameplay and unloading MainMenu

SceneManager.UnloadSceneAsync("MainMenu");
SceneManager.LoadSceneAsync("Room1", LoadSceneMode.Additive);

and loading back into MainMenu

SceneManager.UnloadSceneAsync("Room1");
SceneManager.LoadSceneAsync("MainMenu", LoadSceneMode.Additive);

I can't transition between the Cameras anymore.
GameObject with Main Camera / Cinemachine Brain stays persistent via DontDestroyOnLoad though.

#

Thinking over it, this could be more a cinemachien question so I'll ask it there 😄

timber tide
#

Probably need to tell cinemachine to search the scene again for those virtual cameras

#

Hmm they may actually subscribe via a singleton actually when they awake(), or well that would be the more reasonable way

But when my dropdown menu is open, no matter where i click, it reaches the tile underneath it

UI doesnt block raycast

You have to specific check your cursor is on UI
and if it is you return

but when i click on the arrow again to close it i click on the tile beneath

And you'll get the blocking behavior for free

I thought "Raycast" target would be enough?

#

Only if you're using the event system for clicking tiles

dusky pike
#

(and it also works always, except when i open the drop down)

rich adder
#

yes because UI doesnt block the Physics.Raycast

#

only if you use a Physics Raycaster on the camera then it uses Event System for ray as with UI and its covering it that way works

    {
        return isMouseOverUI;

Hey, this chat usually helps a lot, so I want to ask here first. If i follow this tutorial: https://www.youtube.com/watch?v=IVj7-usBxHo&t=30s Could this be used to create a trail of blood that my player leaves behind? The thing is, I want it to be dynamic so the player not only bleeds but the game sees what asset/what angle the player is standing on so the blood stays on the said asset depending on what part of the player is touching it and what angle the asset is at. Kind of like splatoon paint, but that spawns from the player at all times. Imagine shooting a paintball at something. Or is this too hard of a task for a beginner and I should forget it? Or the trail that Super Meat Boy leaves behind when he touches something but in 3D

Also, this is nothing too realistic, I'll just slap on a super low effort pixel shader on top of everything at the end...

you will need to code that in

#

raycast onto the surface hit then apply the decal projector with a slight offset

#

you can use particle system too but Decal Projectors can be pushed to GPU unlike particle system (performance boost when spawning a lot)

#

VFX graph doesnt work well because it runs on the GPU while unity collisions are processed in physics / CPU so they cant interact

rocky canyon

yea, probably raycast be ur best bet.. esp w/ all the weird edge-cases u were trying to describe

can get normals and stuff and angle ur projectors how they need
