take it with a grain of salt

you do any translations in the coroutine?

that may be the issue to all of it

[swift crag]

it'll matter if anything else moves your transform

[rocky canyon]

but i would figure a coroutine is frame independent

[swift crag]

if your transform is getting moved by anything else, then you'll get different behavior

[tender stag]

i googled it

[rocky canyon]

this is a good point

[tender stag]

its fps dependent

[rocky canyon]

if anything else is tweaking the transform.. its gonna throw off the smooth damp

unless u calculate it independently

[ivory bobcat]

It's just managed data that's updated every time you call it.

[swift crag]

googled what?

coroutines in general?

[rocky canyon]

isLaddering lol

i dig it

[swift crag]

yes, they'll run every frame if you always do yield return null

[swift crag]

consider doing what spawncamp did: instead of smooth damping from transform.position, store your position in a variable and use that

and then assign the result to trasnform.position

[swift crag]

this person is expecting coroutines to run more than once per frame

of course that doesn't work

[tender stag]

alright i’ll get home in 30 mins and i’ll try it

[rocky canyon]

i concur with u.. when I isolated (as you did) zero issues.. but his code is involved to say the least

[swift crag]

yield return new WaitForSeconds(...) tells Unity to resume this coroutine as soon as possible after that much time passes

[rocky canyon]

i think that will solve ur issue 🤞 as minute as it sounds

[swift crag]

Yes, it sounds very plausible to me

[ivory bobcat]

It just damps the value so that you don't overshoot with cameras and whatnot.

[rocky canyon]

this guy see's in slow motion 😆

[ivory bobcat]

Where'd you get this?

[carmine turret]

Does anyone remember how to turn on raycast/spherecast debugging in unity 2023?

[rocky canyon]

youd have to ask Mniszeko

[carmine turret]

I definately remember it being a setting but cant remember where it is ahaha

[rocky canyon]

from my experience you need custom scripts to do that

[carmine turret]

Nah in 2023, there is 100% an option for it ^^

[rocky canyon]

https://github.com/nomnomab/RaycastVisualization

[swift crag]

you mean the physics debugger?

[carmine turret]

I used to use it a bunch

[swift crag]

it's under Analysis

[carmine turret]

thats the one thank you

[rocky canyon]

ohh yea i forgot that exists

[swift crag]

window -> analysis -> physics debugger

go to Queries and uhhh

smash the "everything" button

[ivory bobcat]

I think they're referring to the setting in the settings somewhere

[rocky canyon]

you owe me a keyboard

[rocky canyon]

ya, i forgot about the physics debugger

[carmine turret]

thaanks

[rocky canyon]

i was trying to throw my boy nomnom a bone too 😄

[north kiln]

I have a page containing all the options lol

https://unity.huh.how/debugging/draw-functions

I should add Handles and Gizmos here perhaps...

[rocky canyon]

don't you also have a physics visualizing asset too?

[carmine turret]

wait... does this not work on 2d?

😄

[north kiln]

It's linked on that page with Nomnom's

[rocky canyon]

ahh cool 👍

[swift crag]

It does not, no. It's for visualizing 3D physics.

[swift crag]

This does, though!

[carmine turret]

I dont see why it shouldnt work though since its the same render enging 😦 oh well thank you

enging

new word

[swift crag]

they're completely different physics engines

PhysX for 3D, Box2D for 2D

they have nothing to do with each other

[carmine turret]

Does a raycast count as physics?

[rocky canyon]

ofc

[swift crag]

Yes. But it's 2D physics, not 3D physics.

[carmine turret]

I see, oke

thank you

[carmine turret]

riiip

oh well

[polar acorn]

Nothing is stopping you from just putting a 3D collider on a sprite

[rocky canyon]

Handles are epic.. I'd let them bear my children if I could

[carmine turret]

Would it work with tilemaps though?

Im basically wanting to make a game with grappling and want the player to be kinematic when grounded, and rigidbody when not ^^

(I have no clue how I would manually program grappling hook physics otherwise

[polar acorn]

So what's the 3D element?

[rocky canyon]

tilemaps are such a re-occuring issue/ question..

[carmine turret]

I dont know where you got 3d from?

You suggested to use a 3d collider, and I asked if that would work with tilemaps since they have rigidbodies

[rocky canyon]

ur tilemaps use rigidbodies?

[carmine turret]

apologies, tilemap collider

mb

[rocky canyon]

interesting..

[swift crag]

i presume you have a player with a Rigidbody2D and a tilemap with a TilemapCollider

[rocky canyon]

ohh okay, lol i was wondering

[swift crag]

anyway, to visualize the raycasts, consider using this

[polar acorn]

Ah, I think I missed what the issue was, I thought you were asking about how to use a 3D Raycast in 2D, but you were instead asking how to use the Physics Debugger in 2D

[carmine turret]

ohhhh I see

no worries!

[rocky canyon]

i gotta show my boy some love and try out his asset.. im ashamed to say i havent even used it yet

[polar acorn]

Ignore me, I walked in on a conversation in progress and thought we were talking about a completely different thing

[carmine turret]

yup I just installed it ^^

[rocky canyon]

it happens

[carmine turret]

npnp

Whjilst on the topic, is my idea to use kinematic for ground movement, and rigidbody for grappling and gravity a... good idea?

or is it horrible and going to set everything ablaze

[rocky canyon]

like platforms?

[polar acorn]

It's not a terrible idea, but it's a bit complicated. Normally you'd either bite the bullet and either deal with the fiddliness of dynamic rigidbody movement or coding in your own kinematic grappling.

[carmine turret]

Coding in kinematic grappling sounds awful

🥲

[rocky canyon]

either or sounds exhausting tbh

[carmine turret]

if I had to choose one of those two, I would probbaly do rigidbody movement

and just try to finetune the settings

Gonna try my idea first, see how well it goes.

as a side note.. I cant actually figure out how to install the package, I installed it via package manager, but it doesnt work as described haha.

[polar acorn]

Yeah, but if you want total control over the physics you'd need it at some point. I have no idea how good the physics engine will handle transitioning between the two states but if you don't run into any major issues you can probably get away with it

[carmine turret]

Only one way to find out

Do I need to import fucntionality in the code?

[rocky canyon]

Open the Package Manager from Window/Package Manager
Click the '+' button in the top-left of the window
Click 'Add package from git URL'
Provide the URL of this git repository: https://github.com/nomnomab/RaycastVisualization.git
Click the 'add' button``` you used this method?

[carmine turret]

Because its definately installed

[carmine turret]

already done that part, yeah

[north kiln]

Have you added the namespace?

[rocky canyon]

it should be in ur project already.. then..

[carmine turret]

Do, I know 4 different programming languages, but I dont actually know what that means 🥲

[rocky canyon]

ya u just need to use the namespace.. and VisualPhysics shuld be avail

[carmine turret]

Ive never really googled it. lemme google quickly and understand

[north kiln]

https://unity.huh.how/compiler-errors/cs0246

Though, 0103 might indicate you're using it in a completely invalid place—won't know without seeing code

[carmine turret]

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


public class movement : MonoBehaviour
{
public float speed = 200;
Vector2 move;
Rigidbody2D rb;





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

    void FixedUpdate()
    {
        rb.AddForce(move * speed * Time.deltaTime);
        RaycastHit2D hit = VisualPhysics2D.Raycast(transform.position, -Vector2.up);
        if (hit.collider)
        {
            rb.isKinematic = true;
        }
    }

    // Update is called once per frame
    void Update()
    {
        move = new Vector2(Input.GetAxisRaw("Horizontal"), 0);
    }
}

Thats the entire thing.

[north kiln]

yeah, missing namespace looks like it

[carmine turret]

this section is the namespace I assume?

[north kiln]

No need to presume

[carmine turret]

Not entirely sure where I would find the name of the package

[thorn holly]

I’m a bit confused on trigger vs collision, if I have an object that:
Doesn’t pass through walls, but instead bounces off them
Activates a method and passes through the player
How would I do that? I can code the bouncing, I’m just not sure how to make it pass through some objects and make it collide with others

Also this is 2d top down and I don’t want physics to apply to anything, other than detecting wall collision, and I stuff to move only explicitly.

I believe someone told me how to do part of this, but I just don’t know how to do the different interaction types

[rocky canyon]

trigger you can pass thru.. collision you cant

if u want it to pass thru objects. u can set layers.. and in the physics settings u can manually set what layers interact with what other layers

called the Layer Collision Matrix

you don't have to use Triggers.. just b/c u want something to pass thru it..

triggers are meant to be activated(do something in code).. like if u walk thru a metal detector.. it'd Alert.. and tell the code to do something

[thorn holly]

Ah

[rocky canyon]

    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Player"))
        {
            Debug.Log("We collided");
        }
    }

    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.CompareTag("Player"))
        {
            Debug.Log("Triggered");
        }
    }```

[acoustic sun]

How did you add Adding a Winner Zone trigger to finish the level? Like when creating a game

[rocky canyon]

^ OnTriggerEnter

course you'd want to use something like a tag and CompareTag("PlayerForExample");

to know if it was the player colliding with it.. and not just the ground or something

[sterile moon]

Alright, Im tired of messing with this lol, who wants to make like 10 bucks, maybe more, doing some rigging and maybe programming

I could use people who are interested in my project

[rocky canyon]

i like physics.. and mechanical things..

[sterile moon]

WELL I DO TaKe OfFeNsE nOoB lol

[primal turtle]

why does it work when they do it, but not when I do it?

Instantiate(f1, new Vector3(12, 12, 5));``` is it because I use a tilemap and they used a gameobject? Does that change anything?

[rocky canyon]

before coding.. i was a mechanic and a carpenter

[sterile moon]

funny enough, I am a mechanic by day trade. run my own business

[rocky canyon]

i figured

Oh yeah? What is a P0304

[primal turtle]

was already writing it :)

[primal turtle]

how about the most common, CS1002?

[sterile moon]

P0304 is an automotive error code, I'm being a smart ass since Spawn was a mechanic at one point

[primal turtle]

ahh

pshhhh hack LOL

P0304, Cyl 4 Misfire

[primal turtle]

what would I do to turn it into a transform?

[rocky canyon]

my cars were junk too.. all i had to do is short out the connector with a paper clip.. and count how many times the check engine light flashed

[rocky canyon]

theres a line number w/ the code.. whats the line of code

[sterile moon]

P0301-P0308 (and more for those 10 and 12 cylinder engines of course) are all misfire codes for a specific cylinder. P0420 is catalyst efficience, usually clogged cat

Alright, got that package for you @rocky canyon i assume shoot it at you

[primal turtle]

the instantiate code

I thought that was clear

here it is again

[rocky canyon]

speaking of.. my kia.. is misfiring atm, my valve cover gasket is busted.. and leaking oil on top of the 1 cyl spark plug 😈

[summer stump]

You would not. That doesn't make sense

[primal turtle]

Instantiate(f1, new Vector2(12, 12));```

[sterile moon]

VCG on Kia is pretty easy, YMM?

[teal viper]

Because they use the proper method signature - they also pass in a quaternion, and you don't.

[summer stump]

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

The second parameter is the parent

[rocky canyon]

we're getting off topic.. but i just got some red sealant.. gonna patch it.. a new gasket is 50 bux.. forget that

[carmine turret]

Im confused. my ide is definately configured now but I still dont get errors

[sterile moon]

ill hit you in dms with more info but do NOT use red sealer for gaskets

[summer stump]

If you don't get errors, it is not configured

[primal turtle]

literally what I'm reading on the side... thx anyways

[primal turtle]

wdym?

[sterile moon]

Package is at your door @rocky canyon

[summer stump]

Do you know what a parent is?

[primal turtle]

yes

ohhh

[teal viper]

Do you see all the method signatures in the documentation? Which one fits your call according to parameter count?

[summer stump]

There ya go. It is a reference to the transform component you want to be the parent

[primal turtle]

is there any other way to have the instantiated object go to the position I want without doing that in its own seperate script?

[summer stump]

Look at overload 4 of that link

Note it takes a vector3, NOT vector2

And it requires a quaternion

[primal turtle]

ok

couldn't I move the instiated object afterhand?

[summer stump]

You can do whatever you want

Why not just move it IN the instantiate though?

[primal turtle]

because it's a tilemap so I can't do 3d and it doesn't accept 2d for some reason

[summer stump]

Well 2d is just 3d with a z of 0 (simplifying things)

So that is a non-issue

Just pass the vector2 you had as a vector3 🤷‍♂️

[primal turtle]

I run into that problem

[summer stump]

Because you did it with the wrong overload

You have to use a vector3

Just pass the vector2 you had AS A vector3

As in new Vector3(2,2,0)

[primal turtle]

cannot convert from 'UnityEngine.Vector3' to 'UnityEngine.Transform'

then I get this

[teal viper]

The problem is the param count...

[summer stump]

You are doing it wrong

You must include the quaternion as I said above

[modest dust]

Dear lord almighty

Just look at the docs and see for yourself that there is no Instantiate method which takes ONLY the prefab and position

[primal turtle]

transform.position = Vector3.SmoothDamp(transform.position, position, ref ladderPositionVelocity, ladderStartPositionDuration);```

so basically do that ^?

Sooo im lost as to what I missing regarding this... I have the correct external tool selected, I have the package installed (even have the unity extension in vs code installed)

Did you click regenerate project files in external tools?

THATD be a no.

It's not in the guide unfortunately

where might one find it, its not on the page vscode actually tells you to go to 😄

unless Im blind

(equally possible)

[rocky canyon]

well shit

[carmine turret]

found it on an entirely different page.

[rocky canyon]

idk, is there anything else modifying the transform?

[tender stag]

nope

holy shit

yo

i think i figured it out

after 3 days

YESSSS

[tender stag]

the transform had a rigidbody right

and its interpolate mode was set to interpolate

thats why

i set it to none

[carmine turret]

Pog, its working now. appreciate the help!

[tender stag]

and its working perfectly

[carmine turret]

same for everyone else ^^

[tender stag]

so i just gotta set the interpolate mode to none whenever im laddering

@ivory bobcat @teal viper cause i know u guys helped me over the past two days

if your curious why it didnt work

[teal viper]

Yeah, that makes sense. That's why I said "isolate it entirely"

[tender stag]

do u know what the funny thing is

i changed it by accident

[teal viper]

Well, glad that solves your issue

[tender stag]

thanks guys

its fixed the issue for climbing as well

[carmine turret]

How do I figure out the layer of the raycasts return?

Currently its triggering on the players capsule which is of course not ideal 😛

[teal viper]

Raycast doesn't return a layer.

[carmine turret]

I see

[summer stump]

https://docs.unity3d.com/ScriptReference/RaycastHit.html
Assuming you mean a RacastHit, you can access it through the collider or gameobject

But different overloads return different things

[carmine turret]

Is there a way to make the raycast ignore the player?

[summer stump]

Layermask

Pass in one that doesn't include the layer the player is on

[carmine turret]

Yeah the moment I typed that I thought "wait isnt there a layermask argument for raycast"

xD

[carmine turret]

I would put the number of the layer correct?

nvm I get it.

layermask is an array!

or something similar. Ill work it out

[north kiln]

https://unity.huh.how/bitmasks

[thorn holly]

If I disable a collision on the LayerCollisionMatrix, will triggers still activate?

[summer stump]

I mean, that is basically right yeah. Vertx's link explains it well.

But I just wanted to say that yeah, it can become confusing going from layer INDEX to a layermask.

It's best to just create a layermask variable and set it in the inspector
public LayerMask raycastMask;

[summer stump]

No

[thorn holly]

Hmm. So I have a projectile, I need it to collide with the map in the sense that the projectile will not move through the map and activate OnCollisionEnter, but I need it so the projectile will pass through players, but still activate OnTriggerEnter on the player and projectile

[summer stump]

If it has a trigger collider it will not cause OnCollisionEnter

[thorn holly]

Well, I need it to collide with the map but not with the player

[summer stump]

Can you not just have it destroy itself if it does OnTriggerEnter on the terrain?

Or do a ricochet logic

[thorn holly]

Yeah, do I have to worry about it passing through the wall?

[eternal needle]

i havent tried this personally but maybe adding 2 colliders and setting up the physics layers would be possible.
I would really just have it check against some kind of map layer though in OnTriggerEnter then do your logic

[thorn holly]

like passing through a little bit before it activates the ricochet logic

[eternal needle]

no matter the solution, every wall, floor, or object you want this projectile to hit is gonna have to be a different layer from your player

[summer stump]

You would have to handle that case, yes. It would have to have a rigidbody, and setting it to continuous collision mode would reduce the possibility of penetrating walls at any reasonable speed

[thorn holly]

Well, it wont be going too fast, so that should be fine then

[thorn holly]

do I make the rigidbody dynamic or what?

[summer stump]

Yeah, for OnTriggerEnter

[thorn holly]

How would I stop all physics then?

I don't want my projectile to simulate physics, just do the OnTriggerEnter

[summer stump]

Choose a different method.
Raycast in front of the bullet maybe

[thorn holly]

So raycast, make the length of the ray the velocity's magnitude (I don't actually have rigidbody velocity but just the amount im translating it by) id assume so it doesn't move farther than the raycast, then if it hits a wall, do ricoshet logic, and if it hits a player, do that logic?

[summer stump]

Yeah exactly, that is a pretty robust method, you just need to control all the physics yourself obviously (which it sounds like you want)

You can then do a layermask to be like the collision matrix too

[thorn holly]

What would it mask?

[summer stump]

Layers you don't want the raycast to care about

Well, sorry. To be clear, it would be the opposite. It would ONLY include the layers you DO want to hit

[thorn holly]

Only three layers, map, player, and projectiles

[thorn holly]

So now for the player, I want it to collide with other players and map objects (as in not go through them), but still not simulate physics and I dont need anything to happen on these collisions. Would I do the same raycast and trigger method, but just make it not move if it detects a collision?

[fair steeple]

Hey, I'm having trouble subscribing to an event. It's CrawlStateEnter in Test.cs https://pastebin.com/swbbDyRk

Oddly it throws null exception in only one of the two events and I can call CrawlStateEnter only once.

Everything is referenced in the editor.

[teal viper]

The error has nothing to do with the event. crawlState in Test is probably null. Make sure you don't have other instances of that class in the scene with unassigned references.

[fair steeple]

According to this it's not

[covert sinew]

        if (textboxController == null)
        {
            var _textboxController = FindObjectOfType(typeof(TextboxController));

            textboxController = _textboxController.GetComponent<TextboxController>();
        }

Is there a specific function that finds an object in the scene with a given component, and returns that specifc component, or is this up above the correct way to do that? I'm struggling to find out from what I've been investigating.

[fair steeple]

Seems to be the only game object with CrawlState.cs too

[shell sorrel]

FindObjectOfType<TextboxController>() does just call the generic version

also the one you called does to, you just have to cast the result, but the generic version is the correct one to use

[covert sinew]

so FindObjectOfType<TextboxController>() would return the TextboxController of an object in the scene correctly?

Thank you very much for the help. I appriciate it.

[shell sorrel]

try it, it will return the first TextboxController it finds that is in the scene and active, there is a bool to include inactive if you need

[fair steeple]

Ok, I solved the null error, but it keeps calling CrawlStateEnter only once

[teal viper]

What was the issue?

[fair steeple]

That the event CrawlStateEnter is being called only once, after that it only calls CrawlStateExit

[teal viper]

I mean what caused the null reference?

[fair steeple]

Oh, right

It was a second Test script being instantiated on a random object

[teal viper]

As for the current issue, add logs to where the event is supposed to be invoked and see if it prints.

[lusty flax]

How would I make a track for a moving platform? I want to be able to display where a moving platform will go, because right now it's really hard to know where you'll end up.

[teal viper]

A line renderer maybe?🤔

[lusty flax]

What if I want to make it look nice, with a custom texture for instance?

[fair steeple]

Yes, that was it. I messed the _Start function and forgot to restart a variable causing the function to only run once

[teal viper]

Still a line renderer maybe.

[fair steeple]

Thanks for the help

[lusty flax]

Line renderers do that? Cool... I didn't know...

[shell sorrel]

yeah line renderers do that, it can tile a texture along the line on y axis

[teal viper]

Sure. It just generates the mesh. You can apply whatever material you want to it.

[shell sorrel]

also sprite shape might work for you

[lusty flax]

What if I want the line to be animated (eg., a moving lightning bolt)?

[shell sorrel]

first is it just 1 straight line, or a bunch

[teal viper]

Should be possible the same way as with a regular sprite/mesh renderer.

[shell sorrel]

or a path that curves

[lusty flax]

No, the path is a straight line, so I think a line renderer will work.

Thank you!

[shell sorrel]

if its always 1 straight line, even just 1 nice sliced sprite would work

[carmine turret]

I thought I might try using just rb for the 2d controller, but my character bounces over the tilemap

ive read that this is a limitation of box2d, but that post was from 2016. any ideas?

[swift crag]

i'm not sure what "bounces over the tilemap" means

like, you're getting caught on the boundaries between tiles?

[carmine turret]

Yup

which forces the player to bounce upwards

[swift crag]

i'm just figuring out 2D physics right now myself, so I haven't had that issue yet

[carmine turret]

If I use a box collider for the player instead, the player randomly just stops

[swift crag]

Maybe your sprites are slightly too small.

What if you switch the tiles from Sprite to Grid collision?

it's an option on the tiles, not the tilemap collider

[carmine turret]

I havent seen that. Ill give it a try in a sec

[buoyant schooner]

Am I using unity actions correctly?

using UnityEngine;
using UnityEngine.InputSystem;
using System;

public class PlayerInput : MonoBehaviour
{
    GameActionMap S_GameActionMap;
    public static event Action doSomething;

    private void Awake()
    {
        S_GameActionMap = new GameActionMap();
    }

    private void OnEnable()
    {
        S_GameActionMap.Enable();
        S_GameActionMap.Player.A.performed += ActivateButton;
    }

    private void OnDisable()
    {
        S_GameActionMap.Player.A.performed -= ActivateButton;
        S_GameActionMap.Disable();
    }

    private void ActivateButton(InputAction.CallbackContext context)
    {
        doSomething?.Invoke();
    }
}

It seems that if I invoke my actions in my input script, I'll have a ton of actions declared

Is there a way to declare my csharp public static event Action doSomething;

In the class where I use it?

I thought of using a static class instead, but It feels a little weird to make a seperate static class

[shell sorrel]

you declare it in the place you invoke it

and sub to it else where, where you want to listen for it

[covert sinew]

In an Abstract Class, I want an if statement that checks if the component is of a specific type or not.

Is there a way I can check which specific inheritor of an Abstract Class is being used, or check if a specific inheritor is on the object in question?

[shell sorrel]

if (obj is SomeType objOfSomeType) { ...

[eternal needle]

it feels pretty backwards for the base class to try doing logic based on the child classes, what are you exactly trying to do?

[shell sorrel]

if you need to check for many types there is also a pattern match with switch you can use as well

but yeah it does feel strange for the base class logic to need to care what type extended it

normally this would be for something that consumes the abstract type, and need to work differernt based on what extends it for a edgecase

[covert sinew]

I'm using it to throw errors if variables aren't set, but some of the child classes don't use those variables, and I want to supress the Debug.LogError if the class doesn't use the variable in question

[buoyant schooner]

using UnityEngine;
using UnityEngine.InputSystem;
using System;

public class PlayerInput : MonoBehaviour
{
    GameActionMap S_GameActionMap;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;
    public static event Action doSomething;```

What happens if I want to invoke a ton of actions inside 1 script?
My input script will have like 50 action declarations

My script will start to look like this ^^^

[shell sorrel]

well this is not valid code, but why would you need so many

like you can use Action<T> instead

then pass data into the Invoke when you call it

[eternal needle]

maybe make another child class which specifically handles which variables are needed. A layer between the base class and the actual child class. The base class shouldnt care about this at all, you'll never stop editing the base class everytime you need to make a new child class.
Or maybe just throw some extra logic into the base class like some protected bools so it knows what variables to not check for, and child classes can change those bools

[buoyant schooner]

I need a lot because It's my player input script, If I wanted to map every button to something, I would have a lot of actions

[eternal needle]

just use the new input system, itll do what you're trying to do already and better

[covert sinew]

Maybe I could just change the method in the child class using an override, then?

[shell sorrel]

they are, but are trying to wrap it with static events for some reasons

[eternal needle]

🤨

[shell sorrel]

like you can make as many instances of your GameActionMap to map with as you want

no need to do it all from 1 place

[eternal needle]

You could but itd be slightly annoying because you'll have repeated logic in each class that wants to override it. Ideally you could have some way for a child class to "toggle" what its checking for

[teal viper]

Magic:

public static event Action<Key> KeyPressed

Then invoke that one event with whatever key as a parameter.

[shell sorrel]

even if i was redirecting it through events, i would use only a small amount of events that have args that are passed

such as the enum value or a tiny struct

[buoyant schooner]

I tried doing this:

public class AnotherScript : MonoBehaviour
{
    public static event Action doSomething;

    private void Awake()
    {
        doSomething += SayHi;
    }

    void SayHi()
    {
        Debug.Log("HI");
    }
}

But then I cannot do this:

public class PlayerInput : MonoBehaviour
{

    private void ActivateButton(InputAction.CallbackContext context)
    {
        AnotherScript.doSomething?.Invoke();
    }
}

I can only subscribe events with AnotherScript.doSomething

[eternal needle]

you cannot do that because you cannot invoke events from another class

[buoyant schooner]

hmm, yeah ;/
But some how I can subscribe events from another class

It would make sense to me if I could do this above

[eternal needle]

AnotherScript.doSomething += SomeMethod

if that wasnt an event, just an action, that should be fine to do. but this all seems very weird to even need to do

[shell sorrel]

if the instance it is on matters its common to keep the event static and pass the instance as the first arg

[teal viper]

Events are supposed to have one source and many subscribers. That's why you can subscribe to it from wherever, but can only invoke it from the owner.

[shell sorrel]

but also makes no sense subbing to a event on the same type that defines it

[buoyant schooner]

hmm, what happens if I want to invoke the same event in different scripts?

[queen adder]

hello! when i set up a camera to make it follow a cube and the cube colldies why does the camera fly all ove the place?

[shell sorrel]

what you want to do feels more like a basic reference and function call

like the idea of events is you make it many things can sub to it from all over the code base

[teal viper]

You would request the owner of the event to invoke it. But that sounds like a bad design idea(depends)

[shell sorrel]

and they all see when its invoked

[tender stag]

why when i have lower fps the firerate is slower?

do i multiply it by Time.deltaTime?

like this

[buoyant schooner]

To get around this would making the declaration for this event in a static class be a bad idea?

So, I can invoke the action from any script?

[tender stag]

yeah that works

wait no it doesnt

[shell sorrel]

have it not be a event, but you want for this is strange

[teal viper]

That wouldn't change where you can invoke the event from.

[teal viper]

It feels like you're trying to solve a simple issue with a weird solution. What exactly are your rying to do?

[frigid sequoia]

I can just not use it right now, but I am curious now that I typed it, would something like this result on an endless loop?

[swift crag]

correct

unconditional infinite recursion

it's worse than an endless loop, I guess

Unity just instantly dies when I do that (on macOS, at least)

[buoyant schooner]

I want to decouple my code,

So a trigger can invoke a function without knowing where the function is or what it does

[swift crag]

I very commonly do this by writing

public float Foo => Foo;

[buoyant schooner]

What should I use instead?

[frigid sequoia]

What does that do?

[swift crag]

it's a property called Foo that returns Foo

which is a property called Foo that returns Foo

you can see where that's going

[eternal needle]

to me it doesnt seem like your solution actually is dependent on fps. Maybe ive missed something. This might just be an issue that the fps is too low, and the game is running too slow.
imagine if you had 1 fps, your game is running Update ONCE per second. No matter what you set the nextFire time to be (lets say in 0.1 seconds from now), update wouldnt run within 0.1 seconds and you would at best shoot 1 second from now.
Similarly if you had a fire rate of 1 million bullets per second, your game would never actually run that fast to get 1 million shots out in 1 second

[frigid sequoia]

I have never seen the "=>" before so I am kinda confused by that XD

[swift crag]

indeed -- and there's another problem

suppose your weapon fires once per second

and you're getting 1.1 frames per second

frame 0, t=0: fire. next fire at 1.0
frame 1, t=0.9: don't fire
frame 2, t=1.8: fire. next fire at 2.8
frame 3, t=2.7. don't fire

[eternal needle]

why crosspost this to all 3 channels, read the #📖┃code-of-conduct and delete it. This isnt a coding question.
wtf i just noticed you pasted it to literally every channel

[swift crag]

you're losing a bunch of time

I prefer to do weapons like this

[SerializeField] float fireRate;
private float delay;

void Update() {
  delay -= Time.deltaTime;
  while (delay < 0) {
    delay += 1 / fireRate;
    Fire();
  }
}

This avoids "losing" time caused by frames and the fire rate not perfectly aligning

It can also fire several times per frame, if necessary

[teal viper]

Wdym by "trigger"? And, you can do that with one event with parameters, defined in the class that you originally shared.

[buoyant schooner]

Could you explain why this is a bad design choice please?

[swift crag]

If you don't actually want events, just don't use events.

event is just a way to ensure that only the owner can invoke the method

There's nothing stopping you from slapping a System.Action field on something

[tender stag]

so its fine?

[teal viper]

Well, because that goes against the concept of an event. An event is something invoked in one place with one or many subscribers that could react to it.

[tender stag]

yeah u got a point

[buoyant schooner]

What am I looking for?

where an event doesn't have an owner, I want to trigger a function from any class. But I want this to be decoupled.

[shell sorrel]

feel you are thinking about the purpose of events backwards

[eternal needle]

basically yea, if you do what Fen said then you can ensure the firerate is accurate. Really though as a user, I wouldnt expect my game to fully function if it was running at 10 fps suddenly. A ton of games have bugs with lag

[shell sorrel]

a event is just a message on a system that something happened, and many things can choose to listen to it

its invoked from 1 spot, but listned to by many

[teal viper]

That would be just a delegate.

[swift crag]

I'm more concerned about the subtler loss of fire rate you get if your frame rate aligns poorly with the fire rate

It can be really bad in certain situations

[shell sorrel]

if you do not want this restriction just remove the event keyword

[buoyant schooner]

Thank you 🙂

[tender stag]

how do i fix it?

[swift crag]

by doing this

[buoyant schooner]

Oh,

[swift crag]

of course, making the weapon sound right is another matter (:

if you just play a sound every time it fires, it'll sound a tiny bit choppy

...then again, I never really noticed that in the games where I've used this strategy

so it's probably fine

Anything where you fire multiple times per frame probably shouldn't be playing an audio clip for each shot

[teal viper]

Why would you want to invoke your events from many places though? Assuming it's still for the input use case.

[swift crag]

switching to Fuller Auto and crashing fmod

[buoyant schooner]

Just multiple triggers who want to invoke the same event? I'm just trying to think ahead on how to structure my code.

[shell sorrel]

i feel multiple triggers just makes it harder to follow

when i think of my events they are owned by 1 system

[tender stag]

like this?

[shell sorrel]

but if thats what you want use the same code you have, just remove event keyword from those lines

[swift crag]

Yeah. Just remember to set delay to 0 if you aren't firing and it goes below 0

Otherwise you'll bank up a ton of shots

achieving Fullest Auto

[tender stag]

wait so where do i set it to 0

[swift crag]

if you aren't firing

[buoyant schooner]

oh okay!

[swift crag]

if you are firing, the code already raises delay back above 0 (by firing the weapon)

and only if delay is below zero

[swift crag]

only if delay is below zero.

otherwies, letting go of the mouse will instantly end the cooldown

[carmine turret]

Mmm just a quick query, if I wanted to use 2d physics, can I use 3d models still;?

[swift crag]

Sure.

the only important bit is if you use the URP 2D renderer

it may not play so nicely with 3D models

[tender stag]

so like this?

[carmine turret]

Hmm I did choose urp mode but I supose I could just make a 3d project, and use 2d code

[swift crag]

Right.

[tender stag]

wait so what did this change

i dont understand

[tender stag]

so before it wasnt really accurate?

the firerate

[swift crag]

before what?

[tender stag]

the way i was doing it

[swift crag]

before adding the delay = 0 bit?

or what you had before?

[tender stag]

what i had before

[swift crag]

There were two problems with that logic

One: You can't fire more than once per frame. This isn't very likely to come up unless you have a super-fast-firing burst weapon (or the game gets down to a low framerate)

[shell sorrel]

there are ways to fake multiple shots per frame

[teal viper]

The best approach is to have a hierarchy in you code. At the very top you'll have something like a game manager, that governs the overall game loop. It would hold the topmost events and you can request it to invoke a certain event for something, like game over or game start. Below it would come some specific systems or managers, like PlayerController or something, it might have events like OnPlayerDied or something. Each of these classes would hold ownership of these events and would be the only one invoking them. Since PlayerController would be the ultimate source of truth for the player live/dead state, it would be the only one that can and need to invoke the event. It wouldn't make sense to call the player died event from a random stone in the scene, even if it was involved in killing the player. Makes sense?

[shell sorrel]

but its much more complicated

[swift crag]

Two: You lose any excess cooldown time. So if the weapon is almost ready to fire on frame 1, it sits around for a long time before frame 2 comes around

That time gets lost.

[carmine turret]

egh nevermind, I want the pixelart style ahaha

[shell sorrel]

like if its a projectile, you can calcualte how many shots should happen per frame, then adjust starting positions of projectiles to fake it

[swift crag]

By subtracting the time per shot, you get to keep that excess time

[teal viper]

@buoyant schooner similarly, no other script than GameManager should decide wether the game is over or started, thus it should be the only class invoking these events.

[buoyant schooner]

Yep, that makes a lot of sense!

So, would I be storing my most important actions in this Game Manager? Then I can access Game Manager to invoke the event?

[teal viper]

If you find yourself having an event that many scripts need to invoke, then there's something wrong with assigning responsibilities to your classes

[teal viper]

Again, you can't invoke events from outside. It needs to come from the logic inside the owner.

[swift crag]

the game manager manages the game

it's not just a dumb bag of function pointers

[teal viper]

If it's a game over event, for example, the game manager would be checking the win/lose conditions on update or on certain events and if they're satisfied, invoke the appropriate event that it owns.

[swift crag]

It's fine for other things to tell the game manager about what's happening

like "The player just died"

or "This objective was completed"

[shell sorrel]

also you mentioned some of this is your want to reduce coupling

events do not reduce coupling it just reverses where it is which can be rather helpful at times

[swift crag]

But you shouldn't be grabbing it by the collar and forcing it to end the game

[buoyant schooner]

Hmm, ok!

I guess it would make sense to only trigger an event from 1 script.

I think I need to now look at some example player input script designs

[teal viper]

Your player controller logic should be mostly in the PlayerController, so you wouldn't need to forward input events from it anyway. There might be some exceptions, but for most cases it will be like that. Thus what you're trying to do is confusing.

[buoyant schooner]

But, shouldn't the logic and the input be separate?

[teal viper]

It is though.

The input is handled in the unity input system.

All you do is receive and handle the input, which is the responsibility of the game logic.

You're trying to add additional layer of abstraction for the sake of adding additional layer of abstraction.

Which doesn't make sense.

[crisp anvil]

what am i doing wrong? I setup a list and fill it and when i come to a method inside the same class after the game starts the list is empty.

sorry update hit enter instead of shift enter

[buoyant schooner]

okay, I'll do that then

Thank you

[timber tide]

no clue what im looking at but show how you're creating the list in code

[crisp anvil]

updated. i hit enter early

[timber tide]

Is there a reason you're using Find over serializing it on the editor

[shell sorrel]

they way you are using the input system you are more or less handling the input logic off to it

so it is seperated you are just handling it in your player code

[crisp anvil]

Wouldn't i have to find the ones that get instantiated after the game starts?

oh wait, i guess i could make the list static and add the in the house.cs start or awake method.

[timber tide]

if you're instantiating them at runtime, then yeah you couldn't just serialize them directly, so what you can do is store them somewhere in a container which you can assign on the editor.

and then use the container reference to search through for houses

[crisp anvil]

When i make the list public like the other variables which i can see in the inspector the list doesn't show up even with [serializefield] unless im missing something

[timber tide]

static references / singletons is another good idea too

[timber tide]

should be visable to populate, but you really just need the reference to the object that contains the list as you're probably not inserting anything into it at editor time anyway by the sound of it.

as well as making the list accessable

[north kiln]

Also, please don't use Count() when Length or Count exists, Count() may iterate over the entirety of the collection to calculate the length

[shell sorrel]

90% of cases it wont do that, but it prolly will box things while trying to check if its IList so yeah still would do the check directly

[north kiln]

I wouldn't trust shit in Unity's ancient version of .NET, but yes, it's just bad practise and I hate to see it

[shell sorrel]

still would be a cast you dont need

[crisp anvil]

can dictionaries show up in inspector?

[shell sorrel]

they do not

unity does not know how to Serialize them

[crisp anvil]

ah

[shell sorrel]

are a few work arounds

what are you wanted key and value types?

could have a list of structs, then in Awake loop it and make a proper Dictinary from it

[crisp anvil]

I was using a dictionary before i moved to a list for the simplicity. I got the list to show up and i figured i'd ask if they would too.

[eternal needle]

unity has an example here, maybe you could just use this directly after making a few methods like add/remove.
https://docs.unity3d.com/ScriptReference/ISerializationCallbackReceiver.html
there are implementations online

[crisp anvil]

Ty bawsi

[nimble apex]

i have a UI that is made up by 3 parts, upperhalf , video canvas and bottom part
all 3 UIs have vertical layout group and layout element enabled

im now trying to make a resize algorithm for 3 of them using the min height and preferred height

basically upper half height : video canvas height : bottom part height will be 1 : 0.6 : 0.1 , something like this

but , as you see, it seems that the height i obtained with getrectheight() is not correct

like upper group is 1012, but the actual height is 1596

i think i gonna work on it more first

aight i think im good lol

[primal turtle]

is there a line of code that checks whether the gameobject attached to the script is a game object or not?

sorry,

a prefab or not

[shell sorrel]

if talking runtime code there is not

Instantiate does not really care if something is a prefab or justa regular GO in the scene it can make a instance of either

for editor code its a different story there are a lot of methods for working with prefabs

[primal turtle]

ok,

what about a clone?

is there a way to see whether an object is a clone?

with a script attached to the clone?

[shell sorrel]

Why?

Generally when you instantiate you would just hold on to the returned instance

[primal turtle]

I'm trying to create an endless runner and I have code I want to run only if the game object with the script is a clone

[shell sorrel]

So keep track of the clones as you make them

Or set some data on the script

Or set a tag

[primal turtle]

yeah

but only if it's a clone and not the actually thing because I use the not cloned version as the start.

[shell sorrel]

When you instantiate it returns a reference to the new clone

You can use that to set data on it or modify it

[primal turtle]

can you send me the documentation?

[shell sorrel]

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

[radiant glen]

Yeah... I know okay thanks

[nimble apex]

this is more like a code design problem

have the code inside a function

when you spawn out new object, the clone, call that function as well

so the function can be called on clones only

[covert sinew]

So, this struct:

    [System.Serializable]
    public struct NamedRectTransform
    {
        public Vector2 offsetMin;
        public Vector2 offsetMax;
    }

is being used in this method:

    void Start()
    {
        startLocation.offsetMin = rectTransform.offsetMin;
        startLocation.offsetMax = rectTransform.offsetMax;

        upDelta = (Mathf.Abs(endLocation.offsetMax.x - startLocation.offsetMax.x)) / transitionSpeed;

        rightDelta = (Mathf.Abs(endLocation.offsetMax.y - startLocation.offsetMax.y)) / transitionSpeed;
    }

But when the Start method is ran, startLocation.offsetMax is getting set to a negative number, (I.E, 10 in the editor window becomes -10 in the script)

Why on earth is this happening? Shouldn't offsetMax return the values for Top and Right, as seen in the below picture? The actual number it's spitting out is -349 and -251

[carmine turret]

Ehhh little confused, Im trying to make a rigidbody jump script, but it only "sometimes" runs. any ideas?

    void Jump(){
        if(Input.GetKeyDown(KeyCode.Space)){
            rb.AddForce(Vector2.up * jumpForce * Time.deltaTime, ForceMode2D.Impulse);
        }
    }

This function is being called within the FixedUpdate() method

[north kiln]

https://unity.huh.how/input/built-in-input/input-in-fixed-update

[carmine turret]

Guess it should be in update then 😛

Does the actualy force script need to be in fixedupdate? or is it fine since it is * time.deltatime

[north kiln]

You should not be using deltaTime at all

and it should be in FixedUpdate

[woven crater]

can i have a game object that can be set indivitually and place it as a tile in tile map?

like a button that can activate certain target

[carmine turret]

Huh interesting. I thought you always used it on physics stuf

[radiant glen]

making dialoge and getting this error, trying to make the dialoge start when the UI is set to active, anyone have a function I could use or know how to fix this one?

[rich adder]

you cannot yield inside a OnEnable , it's not an Iterator type

[radiant glen]

Okay, any other way I can delay the function for like .5 seconds, its starting just a bit too fast, also thank you so much

[rich adder]

turn start into IEnumerator, put OnEnable code there instead

private IEnumerator Start(){
...
}```

[radiant glen]

Dude! Thank you so much!

[carmine turret]

Okay, soooo got my movementy decent, but for some reason my character can like "grip" onto the sides of walls 🥲

Otherwise, making good progress!

[rich adder]

put no friction material on character collider might help

[summer stump]

You actually do NOT use it in physics stuff, because physics stuff (like AddForce and velocity) already have it built in

[covert sinew]

What editor works best for editing the Ink Json Files?

Ahhh I gotcha!

[carmine turret]

Won't this affect mobility when walking?

[wild laurel]

can someone reccomend me a book for learning coding in unity , i already have the basics of c#. need somehelp with vector and unity engine module

[rich adder]

should be fine if you're using velocity , add some drag too

[sour ruin]

hi is it possible to get structs to display in the inspector?

[rich adder]

make it [Serializable]

[rich adder]

nah it goes above you class/struct definition

public struct IKNode{
...
}```

[sour ruin]

ah

champion

thank you

[sterile moon]

No matter what I do, my object is moving left and right on the screen, and not moving along its local y axis. My code will follow this message, followed by an image

            // Slider Out
            if (Input.GetKey(KeyCode.P))
            {
                float sliderMoveValue = sliderArm.transform.localPosition.y;

                sliderMoveValue--;

                Vector3 sliderNewPosition = new Vector3(sliderArm.transform.localPosition.x, sliderMoveValue, sliderArm.transform.localPosition.z);

                sliderArm.transform.localPosition = sliderNewPosition;

                //sliderArm.transform.localPosition -= Vector3.up;

            }

            // Slider In
            if (Input.GetKey(KeyCode.O))
            {
                float sliderMoveValue = sliderArm.transform.localPosition.y;

                sliderMoveValue++;

                Vector3 sliderNewPosition = new Vector3(sliderArm.transform.localPosition.x, sliderMoveValue, sliderArm.transform.localPosition.z);

                sliderArm.transform.localPosition = sliderNewPosition;

                //sliderArm.transform.localPosition += Vector3.up;
            }

The commented out part was a different attempt

[timber tide]

start throwing in some logging

[sterile moon]

I dont even know what to log at this point, like, i see it going the wrong way when it shouldnt be lol

[rich adder]

those are vector3 , start drawing some gizmos

Gizmos.DrawSphere(sliderNewPosition, 0.22f)

etc.

[sterile moon]

should Sphere be an option because I dont have that

[rich adder]

oh sorry is Gizmos..

[sterile moon]

no worries, had me think there was more broken here than just my brain

[rich adder]

https://docs.unity3d.com/ScriptReference/Gizmos.DrawSphere.html

draw some lines too

[timber tide]

nothing is broken, you may be offseting position without taking account of rotation

well, as far I can tell by the image

[sterile moon]

im telling it to move positive and negative on the local y, which should follow that green arrow perfectly

[timber tide]

but yeah, gizmos a good idea

[rich adder]

maybe just do transform.up * amount

[sterile moon]

Is that relative to global or local

[rich adder]

that takes rotation in account

is local

[sterile moon]

so

sliderArm.transform.localPosition += transform.up * 1;

same thing

No matter what I do I tell it move and it moves, the wrong way

when I try telling it to move on the local y it moves towards the front and back of the truck only, versus up at the angle its supposed to, and even that the transform gizmo shows it should

[rich adder]

you in local pivot mode ?

[sterile moon]

Im in pivot, and local yes

[dim brook]

How do i load this sprite?

I want to call the poisonsprite

[sterile moon]

You making a Pokemon game?

[dim brook]

ya

[sterile moon]

Dope af

[rich adder]

just link the sprites in the inspector

[rich adder]

does pivot change if you remove it out of the truck hierarchy

[sterile moon]

nope, doesnt seem so

[dim brook]

so i cant do a pathing thing for it

[rich adder]

hmm btw ur also missing Time.deltaTime to make sure ur moving consistent

[stuck jay]

It's hilarious how many people ask us the best way to link GameObjects without using GetComponent

[dim brook]

unless i make an image for each individual sprite

[stuck jay]

Why does it have such a bad rep?

[sterile moon]

good to know

[rich adder]

You can but you have to know how to grab the sprites within that texture

[teal viper]

You can if you use it correctly. Did you read the Resources docs?

[dim brook]

nope

ill take a look at that

[rich adder]

the image is called status

[stuck jay]

The basic jest is that you make a folder called Resources and place the sprite there

Depends on the path you chose

But everything has to be under Resources

[dim brook]

ah

well i have all of those sprites under an art folder

[rich adder]

no idea why people don't just use fields for basic tasks lol

[sterile moon]

I have to step out for a bit but if anyone has any other ideas on why this object refuses to move along its local y axis, tag me

[stuck jay]

Well to be fair, linking the 7th script in the inspector gets annoying when you have many objects

Especially if you're going for a heavy component based system where one object could have 20 or so scripts

[rich adder]

20 scripts??

also events ..

and simple DI

[stuck jay]

If you do it right, you'll be able to implement systems easily in the future by just attaching scripts instead of having to hardcore every action

You'll actually end up with less duplicate code this way since you won't have to rewrite your health system on every single thing

[rich adder]

not everything has to be a monobehavior

[stuck jay]

True, but a lot does

[dim brook]

ok so ive put the sprites into the resources folder

and ive called them

but theyre still a white box

[static bay]

Pokemon?

[stuck jay]

Having a DamageOnCollision script instead of hardcoding it to enemies and players means you can easily make another GameObject damage the player on collision, so maybe you want to make a wall damage you in the future

[dim brook]

for reference

yea

[rich adder]

just..make fields..lol

[static bay]

Better yet, a SO to hold the sprites.

[dim brook]

what

[rich adder]

yeah but thats too complex in code beginner prob

[dim brook]

like field as in

[stuck jay]

Public Variables

[teal viper]

I think spliced sprites are accessed via the parent sprite name. It kinda acts as a directory. Might be wrong though.

[stuck jay]

Or, SerializeField private variables

That's probably better

[woven crater]

how do i edit layers property to include or remove specific layer inside a script?

[clever oar]

Hello, how to add libraries of sensors into unity? They arent in git. They are only downloadable from their web

[rich adder]

just pass the layer?

[woven crater]

by index or by name and how

dumbpang

[rich adder]

[SerializeField]
LayerMask layers;

private void Method()
{
    circleCol.excludeLayers = layers;
}```

[nimble apex]

can you override the fields of certain component and make them unchangable?

[rich adder]

uh idk what you mean, maybe this?
https://dbrizov.github.io/na-docs/attributes/meta_attributes/read_only.html

[woven crater]

ah yes i know that. but i wonder i can just include layer or remove one from a property of a component.... i guess like this?

[timber tide]

Doesn't work? Also try not appending the value, let the variable be the distance from the origin. Not exactly sure what way you're trying to extend, but try other directions.

no, doesnt work. its weird. It moves it along the global Z not the local y

now idk if its ACTUALLy moving it along the global z or not, but thats the axis its moving in the directions of, whether by coincidence or actually following it idk

[topaz thistle]

I am trying to create a basketball game, and I am having an issue with the setting menu. It contains the option to change the sprinting keybind, however, the keybind text (seperated from the keybind selector) becomes empty as soon as the game starts. https://www.toptal.com/developers/hastebin

[languid spire]

your paste is empty. Ah, you posted the wrong link

[sterile moon]

Hey Steve, maybe you have an answer to this weird one I got

[sterile moon]

Here it is

[topaz thistle]

My bad 😅https://hastebin.com/share/sunepinuvu.csharp

[languid spire]

sprintInputButton.text = PlayerPrefs.GetString("SprintKey");
you need to supply a default value to be used when the string does not exist

[topaz thistle]

Sorry I should've clarified, the sprintInputText is what I'm talking about here

[languid spire]

then why this?
if (sprintInputButton.text == "Awaiting Input")

[topaz thistle]

So there's a button next to the sprintInputText

(sprintInputText is "Sprint:" btw)

And when that button is clicked

It is set to "Awaiting input"

Once you have clicked a key

It is set to that key

It's not currently working right now either, but that's a different issue

[hot wave]

https://www.youtube.com/watch?v=3BOn2gs7z04 when I apply this on my character controller and when i touch rigidbody objects, I get launched upward with rigidbody, why

[languid spire]

I'm confused.
In start you do
sprintInputButton.text = PlayerPrefs.GetString("SprintKey");
in Update you do
sprintInputButton.text = keycode.ToString();
PlayerPrefs.SetString("CustomKey", keycode.ToString());
So how does the Pref SprintKey ever get set?

I've fixed the issue, thanks for your help anyways!

[languid spire]

One point. TextMeshProUGUI is probably not what you should be using. TMP_Text is likely a better choice

[topaz thistle]

Ah, yes I see now. Thank you!

when I use character controller, and followed the code, it pushes the rigidbody upwards at extreme speed :x why

looking at this again, it seems fine honestly. The only other thing I can think of is that the pivot is at the bottom perhaps but I think you mentioned it's not.

[brazen canyon]

What the heck is this error ?

[burnt vapor]

Does this error continue to appear?

If no, ignore it

Probably this https://issuetracker.unity3d.com/issues/error-messages-are-shown-when-using-a-list-of-serializereference-objects
So internal and can be ignored or fixed if you upgrade

[candid tree]

a way to retrieve all objects without having to add "public float" in the script because it would be very complicated if you had to add them all one by one

[brazen canyon]

Well when ever I run the game it happens

[burnt vapor]

It's a Unity bug so you'll have to upgrade to have it fixed, apparently

[brazen canyon]

Thank you

[eternal needle]

Is there a question here?

[candid tree]

I apologize in advance, so what I mean is is there a way to retrieve all the objects in this game without adding "public float" to the script?

[ruby python]

Mornin' all,

So, I have this ship controller (it's very basic atm, just trying to get the basics working), but I think I have order of operation or something wrong.

Idea being that when you hold a movement button, the rcs thrusters fire for that given direction of travel.

https://pastebin.com/tG7X3tP2

The issue I'm having is that for some reason the forward/backward thrusters don't fire unless I also hold down either the left/right key. It's very odd.

[eternal needle]

If you're trying to store the number of objects that exist, then there are many ways.
You could just drag all the objects to some array/list and use the length of the collection.
Or have some script on each object notify another 1 script that it exists and then add to a counter.

[candid tree]

do you know how to make a list in the script?

[woven crater]

any idea why stuff with shader graph broke?

oof make a new shader graph and everything changed

[tulip cliff]

Guys I have a quick question, I’m trying to make an open world game with different characters and every character has its own abilities. Basic movement is on the ground and there are abilities like “dash” or “sprint” etc, but also abilities like “fly” or “levitation”. I used a CharacterController to move until now but should I switch to a RigidBody addforce / velocity to better control the movement ?

[eternal needle]

Yes it's just a List<whateverType>. Google has many resources on it, though this will rely on you dragging all these in during editor time.

[visual hedge]

noob question:

    [SerializeField]
    [Range(1, 10)] [Min(1)] protected int targetCount = 5;
    public int TargetCount { get => targetCount; protected set => targetCount = value; }

    //pseudocode:
    TargetCount = 3;

based on this pseudocode on top: what is targetCount now? 3 or 5?

I am not understanding the get set thing yet

[ruby python]

In the pseudo code you're overriding everything that came before it, so 3.

[eternal needle]

None of this shows your actual movement logic, you should debug and find out why these values either arent what they should be, or why they arent being used properly in the movement logic.

[languid spire]

you are doing
KillAllRCSThrusters();
unless keys from both sections are held

[ruby python]

The movement code is lower down and works fine.

[visual hedge]

so it will change the initial value of that targetCount?
Okay... but is the TargetCount (if we would not set TargetCount to 3) will be passed to other class, other class won't be able to override that targetCount, right? or still?

[ruby python]

Ah okay, I'll have another look at it, thanks. (been looking at it for a while so missed that obviously. lol.)

[eternal needle]

I cant seem to see it on mobile but seems someone else solved that

[ruby python]

Oh the movement code isn't in what I posted (it's in FixedUpdate()) Wasn't relevant to the issue.

[brazen canyon]

BTW just my Unity Editor or Unity Hub ?

[burnt vapor]

Editor

[candid tree]

how bro, im newbie sorry

[eternal needle]

The initial value is still gonna be 5 but when you change it through the property to 3, it will be 3. Since it's an int, if you pass it to another class, the other class wont be able to change it unless you use the ref keyword. Child classes can change it directly since it is protected

[eternal needle]

If you dont know how to use a list I suggest you do some c# basics first, or really just find an example on google. There isnt much more I can do other than write the code for you

[candid tree]

oke bro thank u

[visual hedge]

daaang... I guess I have to watch some documentation about get sets and maybe some tutorials 😄 But thank you

[errant canopy]

I'm getting back into Unity and working on a simple player controller script: https://paste.mod.gg/hmctgecldcgq/0

I'm having a problem with the player "phasing" through objects and I believe I kno why.
Under my PlayerMove() method I'm translating the transform based on the movement direction and speed. If look straight forward I can go through objects pretty easy but if I look down it's just jittering. So I believe there is something going on there causing me to have this issue.

[warm flame]

i will paypal anyone 10 pounds if they help me with my problem (My problem is that when i pull out my gun the gun doesnt want to shoot ive been following a tutorial from a guy called HawkesByte and when i am this part where i cant shoot when i take out my gun its quite useless please help lmao)

[eternal needle]

There isnt much to it, the get is public so anyone can read it. The set is protected meaning only the existing class and child classes can set it. It would be the same if you had a method
publuc int GetValue() and protected int SetValue()

[visual hedge]

okaay, now it's much more clear. Thank you

[ruby python]

Just a very quick look, but your player move should ideally be in FixedUpdate()

[errant canopy]

Right yeah, JUST noticed that haha, but I don't think that'd be the reason for the issue

[visual hedge]

is there a way to make that initial variable not being able to be modified even by existing and child classes?

[timber tide]

you shouldnt be using transform.translate either if you're using rb, no?

[languid spire]

Dont mix Rigidbody and transform movement

[ivory bobcat]

You can explicitly teleport with transform though.

[errant canopy]

I can't remember, but would MovePosition be the one to use then?

[languid spire]

yes, that will respect physics. rigidbody also has a position property

[fleet breach]

Hello this aint a code question but i cant find the "On click" section

the left side is a YT tutorial but i aint got it on my inspector

[languid spire]

scroll down?

[errant canopy]

But I see an issue that because I'm setting these in PlayerMove

cameraZ.y = 0;
cameraX.y = 0;

Wouldn't I just be going to Y 0 all the time?

[rare basin]

scroll down or hide the "Fart" panel

[fleet breach]

OH found it

Thanik you !

[ruby python]

Ah crap, my bad, was looking at the image wrong.

[languid spire]

I presume that the rigidbody is on the player not on the camera

[errant canopy]

Yeah, but I'm moving based on the camera direction

Vector3 movementDirection = cameraZ * verticalInput + cameraX * horizontalInput;

[languid spire]

should be ok to replace transform.Translate with rb.MovePosition

[errant canopy]

It's just setting the player y to 0

[languid spire]

yes, of course

cameraZ.y = 0;
        cameraX.y = 0;

        Vector3 movementDirection = cameraZ * verticalInput + cameraX * horizontalInput;

movementDirection.y will always be zero

[errant canopy]

Yeah

So I'm not sure how I can use the MovePosisiton

if y is 0

[languid spire]

but it was 0 before when you used Translate, nothing has changed there

[errant canopy]

It was working before since I wasn't using the Y in translate?

[languid spire]

I see what you mean. So you need to put the current rb.position.y back into movementDirection

[errant canopy]

Sorry I'm really not the most experienced and I've forgotten most I knew, how would I do that 😅

[languid spire]

seriously?

Vector3 movementDirection = cameraZ * verticalInput + cameraX * horizontalInput;
movementDirection.y = rb.position.y;

[errant canopy]

Ah, sorry misunderstood, thought you meant to the equation

But still seems to be doing it 😅

[languid spire]

Ah, yes, you probably want transform.forward.y rather than rp.position.y as you are calculating a direction.
or

 Vector3 movementDirection = cameraZ * verticalInput + cameraX * horizontalInput;

        Vector3 pos = new Vector3(moveSpeed * Time.deltaTime * movementDirection);
        pos.y = rb.position.y
        rb.MovePosition(pos);

[ruby python]

Ooookay, I think I'm monumentally stupid, but I can't see why this isn't working.

I've split my controller script up to make things a little easier to read and a little more 'direct' (I know it's not overly 'elegant' lol.).

Annoying thing is that I had this working a couple of minutes ago, but it suddenly stopped behaving.

The forward/back rcs thrusters no longer fire at all.

https://pastebin.com/QYQdkELM

Any ideas anyone? 😕

I know that the values are working correctly because the ship moves (the 1, -1, 0 values get passed to my movement section just fine.

[languid spire]

Again, the thrusters will only work if both key sections are pressed

[ruby python]

Yeah, was literally just about to type that I think that was the issue. Think I should take a break to clear my head a little. lol.

[languid spire]

I think all you need is

if (flyMoveSpeed == 0 && turnMoveSpeed == 0)
    {
        foreach (VisualEffect rcsThruster in moveForward_Thrusters)
        {
            rcsThruster.SetFloat("EmissionRate", rcsThrusterMinEmission);
        }
        foreach (VisualEffect rcsThruster in moveBackward_Thrusters)
        {
            rcsThruster.SetFloat("EmissionRate", rcsThrusterMinEmission);
        }
    }

instead of testing each for zero seperately

[ruby python]

Yeah I was just trying to 'split it up' to make it easier to read. But I'll give that a go, thank you 🙂

[hot wave]

in interactor script when i try to access interactable script public Interactable interactable;when doing this itemDictionary[interactable.itemType] I get null exception, why?

i know it has a value, by why cant it find the value

difficult

[languid spire]

either itemDictionary or interactable is null. So debug them to see which one

[hot wave]

Debug,Log(itemDictionary[interactable.itemType])?

[languid spire]

no, that tells you nothing

[hot wave]

how do i debug them?

if ok

that is how I check if they have value, but they cant find the value

[languid spire]

if (itemDictionary == null) Debug.Log "itemDictionary is null";
and the same for interactable

[hot wave]

ah okok, I will try

but I go cook rice first, I go back in a bit ok

[errant canopy]

You can't make a new vector with only 1 argument

[languid spire]

mb, should be, of course without the new Vector3
Vector3 pos = moveSpeed * Time.deltaTime * movementDirection;

[errant canopy]

But if you do this, the player only moves a tiny bit and goes back to 0 when let go

[modest dust]

probably because you set the position elsewhere

[errant canopy]

https://paste.mod.gg/gfpdotqhjzpq/0

Don't believe so

[keen dew]

The MovePosition parameter is a position, not a direction

so it should be Vector3 pos = transform.position + moveSpeed * Time.deltaTime * movementDirection;

[errant canopy]

Ah perfect

Thanks for the help 👍

[hot wave]

interactable is null it said

I have public Interactable interactable; and has the interactable = hit.collider.GetComponent<Interactable>(); but only on the bottom/after this thingy itemDictionary[interactable.itemType], and not before, is that what is causing it?

        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        if (Physics.Raycast(Camera.main.transform.position, Camera.main.transform.forward, out hit, itemDictionary[interactable.itemType], interactableLayermask)) //when raycast finds something
        {
            
            var selection = hit.transform;
            selectionRenderer = selection.GetComponent<Renderer>(); // Assign selectionRenderer here
            if (selectionRenderer != null)
            {
                selectionRenderer.material.SetInt("_enableFresnel", 1); //enable fresnel when in sight
                ///Debug.Log("logging");
            }

            _selection = selection;

            if (hit.collider.GetComponent<Interactable>() != null)// if it find that interactable is in, used to be false instead of null
            {
                if (interactable == null || interactable.ID != hit.collider.GetComponent<Interactable>().ID)
                {
                    interactable = hit.collider.GetComponent<Interactable>();
                    currentInteractTimerElapsed = 0f;
                    Debug.Log("New Interactable");``` it is kind of like this, but ``itemDictionary[interactable.itemType]`` is null

not sure why

[keen dew]

Well obviously there's not going to be anything in the variable before you put something in it

Why are you using it in the raycast anyway?

[hot wave]

so that it can find an interactable item and it could be interacted, not sure if right, itemDictionary[interactable.itemType] is for itemtype, different items have different ranges to be interacted

like if it is broom (itemtype 1), it will have a range of 2, and if it is car (itemtype 2), the range is 6

[keen dew]

You can't select the distance of the raycast based on the thing that the raycast might hit, that makes no sense

[hot wave]

    {
        /*rotationDictionary.Add(1, (new Vector3(-30, 0, 0), new Vector3(30, 0, 0))); // Example values for item type 1
        rotationDictionary.Add(2, (new Vector3(20, 0, 0), new Vector3(0, 0, 0))); // Example values for item type 2
        rotationDictionary.Add(3, (new Vector3(0, -10, 0), new Vector3(0, 0, 0))); // Example values for item type 3*/
        itemDictionary.Add(0, 12f);
        itemDictionary.Add(1, 2f);
        itemDictionary.Add(2, 6f);

    }``` i made a dictionary for them

[keen dew]

You have to make the raycast without the max distance, then after it has hit something check the distance

[hot wave]

ah okok, I thought it would work simultaneously

but i have to check the item type of interactable for the range, how would that work?

and how would no range work? leave it blank or no

[keen dew]

if(hit.distance <= itemDictionary[interactable.itemType])

itemDictionary is a bad name for it btw and using a dictionary for this purpose is questionable

[hot wave]

I want to add other elements for the item also, but not sure which to use

I only know dictionary and enum atm

it is like, I want to make itemtype, but it will have their own characteristic, and it would only be called by their number

or maybe rename it to rangeDictionary?

[keen dew]

Variables don't usually have their type in their names. I'd call it maxInteractionRange

[hot wave]

i still get NullReferenceException: Object reference not set to an instance of an object

interactable is still null, but interactable not being null is dependent on the raycast

I want to learn how to stop null exceptions also,if there are other tips, if ok

I always have a difficult time when trying to use codes that arent declared yet, but needs to be put in an area before the declared code, maybe why it is null

[hidden sleet]

I'm about to work on an inventory system for a shooter type game, so the npcs and player would have stuff liek grenades, guns, ammo and whatnot. For this inventory, what might the best approach be? I'd want said inventory to just be of one type, so would making a 'slot' class that just holds the name of the item and maybe some ID from an item database be a good approach? In that case, how could you track individual details like the ammo in a weapon etc? I'm not too sure what the general class structure for a system like that might look like

[keen dew]

The check is too early

[fleet breach]

question can we make a shopping app on unity ?

[charred spoke]

Yes

[hot wave]

but it wont work as intended if the check is later, or is it ok?, can i move interactable = hit.collider.GetComponent<Interactable>(); up?

[charred spoke]

But why would you use an entire game engine to make a shopping app is another thing

[loud python]

Hey does anyone know why this is grabbing both instead of just 1? https://gyazo.com/e14c4546372b20fc7d20be4d586a4bf5

[keen dew]

if (hit.distance <= itemDictionary[interactable.itemType])
{
    interactable.isHighlighted = true;
    if (Input.GetKeyDown(KeyCode.Mouse0))
    {
        Debug.Log("Toggled");
        targetObject.SetActive(true);
    }

    if (Input.GetKey(KeyCode.E))
    {
        //Debug.Log("it works");
        // Perform radial interaction here
        PerformRadialInteraction();
        if (Input.GetKeyDown(KeyCode.Mouse0))
        {
            currentInteractTimerElapsed = 0f;
        }
        UpdateInteractProgressImage();
    }
    else
    {
        currentInteractTimerElapsed = 0f;
    }
}

this is the only place where you need to check it, if I read the intention correctly

[weary finch]

Looks like its detecting the parent instead of the childs

How are you handling the mouse click?

[hot wave]

the reason why i want it earlier is because of if (selectionRenderer != null) { selectionRenderer.material.SetInt("_enableFresnel", 1); //enable fresnel when in sight ///Debug.Log("logging"); } else, fresnel wouldnt follow the range, or would it cycle and be reachable by fresnel?

item type have different ranges for both fresnel and interaction

[keen dew]

Do you want the fresnel shown on any object, interactable or not?

[hot wave]

only on interactable

[keen dew]

Then you need to move that code lower, where it checks if the object is interactable or not

[hot wave]

okok so it goes like main update code-> itemDictionary (or max range)-> fresnel code?

[weary finch]

(cache your get components pls)

[hot wave]

I dont know how yet, but I want to check

[weary finch]

I mainly see this code, at line 108

if (hit.collider.GetComponent<Interactable>() != null)// if it find that interactable is in, used to be false instead of null
{
    if (interactable == null || interactable.ID != hit.collider.GetComponent<Interactable>().ID)
    {
        interactable = hit.collider.GetComponent<Interactable>();
        currentInteractTimerElapsed = 0f;
        Debug.Log("New Interactable"); //something
        // Access the itemType property of the Interactable component
        // Add your logic based on the itemType here

    }
  .
  :
}

[keen dew]

You'll have to learn to read what the code does. It runs one line at a time, from top to bottom. If you just read out loud what the code does you can see if it's sensible or not ("Enable fresnel. If the item is interactable, check keypresses..." oops)

[loud python]

hmm... mouseclick I will set later but for now its this "public void OnDoubleClick()
{
chestManager.Remove(itemWeapons);
Destroy(gameObject);
}"

[weary finch]

that could be done to this

interactable = hit.collider.GetComponent<Interactable>();
if(interactable != null){
        currentInteractTimerElapsed = 0f;
        Debug.Log("New Interactable"); //something
  //Do the other things from line 120 down
}

[hot wave]

ah, it should be if item is interactable -> (put range here for fresnel) -> enable fresnel and check key presses, I think it would work like this better, hmm what do you think?

[weary finch]

i meant, how are you handling he drag, sorry

[hot wave]

wait I go eat thank you for the help so far

go eat also ok?

[loud python]

I think the drag is automatically part of Scrollview gameobject

is it?

[weary finch]

Mmm, i don't think so, but i might be wrong, it was a long time since I worked with UI but normally I had to implement it myself the click, raycast, find object, move and snap to mouse position

[loud python]

because ive noticed when I have the button click logic in, it doesnt click the one I want,

[loud python]

Nope I did none of this, it goes for me Canvas>Scrollview>Viewport>Content

and I think its in there somwhere the drag component

weird...Icant find anything

it was just automatically applied when I created the button

here https://forum.unity.com/threads/scrollview-with-drag-scrolling.1195807/

So its a behavior the is part of scroll view.

so wtf is wrong with my thing lol

ohhh these item prefabs are all child of the scroll veiw, could this be the reason?

and if so, how to fix?

[woven crater]

what is secondary texture?

[wintry quarry]

In what context?

[woven crater]

im following this tutorial by Brackeys. but idk whats the use of secondary texture

[wintry quarry]

Be more specific please, I don't have time for a 15 minutes video right now

[woven crater]

nvm i think i got it

[swift crag]

I don't know the answer for this specific case, but more generally:

you can use textures to store much more than plain color data
