[crimson sinew]

1. Did you save the code after you cut out the animation playing code?
2. Is there some animation input that has the animation left over from being in previous runs or smth, idk

[faint osprey]

yeah i saved the code and wdym?

[noble summit]

why is networking so hard

[timber tide]

because you can't be lazy about your serialization and data coupling

[polar acorn]

Do you still have an animator on the object, and does that animator have a transition into the clip you were playing

[turbid robin]

i want to add a logo at the start at the application, near the unity one. is it possible? if yes how?
i am making an AR app, is it still posisble?

[summer stump]

It is possible. Make a scene

[polar acorn]

Yes there's literally an entire section in the player settings for adding a splash screen

[turbid robin]

ok then? finally i can make screens

[polar acorn]

Project Settings -> Player

[turbid robin]

wait were project setting is?

[polar acorn]

https://docs.unity3d.com/Manual/comp-ManagerGroup.html

[turbid robin]

oh found it thx

[eternal needle]

Most people in this channel would definitely recommend you dont do multiplayer as a beginner. This is like asking "why is flying a plane so hard" when you just learned to ride a bike. Some things are not meant to be done early on in your career and that's just the simple truth of it

[turbid robin]

what is default cursor? in project settings > player

[polar acorn]

Why are you looking at the cursor

also you can check the page I linked for what anything does

[turbid robin]

idk, i see that option

[mortal bridge]

Definietly. Maybe try Coop local multiplayer first

[polar acorn]

Yes, because it's on the page. Why are you trying to edit it though

you were not asking about cursors

[turbid robin]

i found that option under the icon, i need also the icon

why do i get this allert when i start the app?

[eternal needle]

Multiplayer is still multiplayer. Local coop is still gonna be harder than the basic game, since this is the beginner channel I wouldnt recommend any at all. It's still gonna require them to use mostly proper code architecture which most beginner tutorials do not follow

[mortal bridge]

I completed all Unity pathways. In junior programmer they literally ask you to make a coop game

local multiplayer

[barren violet]

Currently 3/4th through junior programmer. Is that task the last one? I’ve taken Unity essentials. What is the next pathway after junior programmer?

[mortal bridge]

If I remember correctly they ask you to do this for the bonus challenge of car game

I think after junior programmer you are pretty much set to make simple games on your own getting help from Google

@barren violet

Do the bonus challenges. They teach you a lot (in my opinion)

[barren violet]

Ok cool. I look forward to gettting there

[mortal bridge]

and If you decide to take other pathways after junior programmer dont dive into it right away.

practice what you've learned from junior programmer first

[mortal bridge]

Actually if you are 3/4 done with junior programmer you should have been given multiple bonus challenges to do

[barren violet]

Yes but I haven’t came across any coop

[mortal bridge]

It is here my man

just google Junior programmer bonus car game

[barren violet]

Thx

[eternal needle]

Not really sure what you expect as an answer, my initial message wasnt addressed towards you. I havent done the pathway myself but i doubt it is asking you to make a full game

[summer stump]

Plus it is walking you through how to do that specific game I would assume
Which would help, but not every game is the same

[timber tide]

[SerializeField] private UISlot UISlotPrefab;
//or
[SerializeField] private UISlot uiSlotPrefab;

What do you prefer for abbreviations with private fields?

[zealous oxide]

hey friends, i've read somewhere that instantiating numerous identical copies of a prefab from a game object, eg instantiating identical coins from an enemy when they die, is not hardware efficient, if that makes sense. what are the alternatives? is object pooling significantly better?

[mortal bridge]

It is not a game of course. Its just for basics for "beginners" as you said

an introduction

and they ask you to do this like one day after you start that pathway

so its not that hard its not that advanced stuff to make local coop

[eternal needle]

You can find what the actual standard is online, but personally would do the 2nd one regardless of what the answer is

[timber tide]

yeah but feels bad so maybe the best thing to do is just rename it lmao

[eternal needle]

Object pooling is a way of reusing objects. You will have to instantiate them at some point regardless. Depending on the use case, it really might not matter. Targetting PC and you these coins spawn like once a minute? Then itll have 0 impact on performance

[zealous oxide]

thanks for the tip

I've got another question which i'm going to try my best to articulate. in a roguelite/like, when you have a load of items that affect a character in passive ways eg add a poison damage to an attack or give a character a stat it previously didnt have eg + 10 damage reduction, do those stats need be written into/exist in the initial character script so they can be modified by items down the line? so the stats already all exist within the character script but gaining the items then changes the stats/variables in question? I guess another way of articulating this is, is it possible to rewrite one script from another at runtime, assuming im not using scriptable objects (sorry if this is a bit confusing, im new here)

[eternal needle]

This is just a matter of defining what the base stat is, and then adding to it based on your list of items. You will need to define what a stat is so you can add to it, and it's possible you can give a player no stats then add them to like a dictionary. I find it better to just give them all stats but Initialize them all to their default value (likely 0)

[timber tide]

you can pretty much give everything an ID and just write those if you wanted to

[eternal needle]

I just use enum which is basically the id

[timber tide]

Yeah, some identifier + lookup table

if you did have some like random stated weapons that generated with a range of stats, then you'd probably have to write those as their value types.

[zealous oxide]

yeah the default value (0) is what i've done in my very first prototype but I didnt know if theres a better way to do it. its not really the items i'm worried about, its more about oh now I want this character to have an effect or on hit/kill effect it previously didnt have, does the action need to already exist within the script for it to happen or is there some way I can inject the variable, and then add it at specific points within the script at runtime

[timber tide]

scriptable object your kill effect and add a identifier

on load, lookup what the ID pertains to and construct your object again.

[swift crag]

I have a scheme that copies the SO's asset GUID into the SO

using UnityEngine;

#if UNITY_EDITOR
using UnityEditor;
#endif

public abstract class Identifiable : ScriptableObject
{
    [SerializeField] Guid _guid;
    public Guid Guid => _guid;

#if UNITY_EDITOR
    void OnValidate()
    {
        var path = AssetDatabase.GetAssetPath(this);
        _guid = new Guid(AssetDatabase.AssetPathToGUID(path));
    }
#endif
}

It uses a custom Guid class

System.Guid is non-serializable

https://bronsonzgeb.com/index.php/2021/09/11/the-scriptable-object-asset-registry-pattern/

[zealous oxide]

i got 1 more. is there a more effecient way of setting an enum from one script to another, than what i've had to endure here: (bear in mind the enums are exactly the same across the 2 different/separate scripts for the 2 different/separate gameobjects)

[swift crag]

I use Json.NET to serialize and deserialize data. I have a custom converter for Identifiable that looks the GUID up in a dictionary that I build before the game starts

[rich adder]

ever heard of switch

[verbal dome]

I wonder why that is

[zealous oxide]

nope!

[rich adder]

doesnt unity have a GUID struct?

[swift crag]

why do you need the pile of if statements?

are these two different enum types?

[verbal dome]

Seems to be just a string?
https://docs.unity3d.com/ScriptReference/AssetDatabase.AssetPathToGUID.html

[zealous oxide]

no theyre exactly the same, but theyre in 2 different scripts and I cant work out a better way of doing it (im new to this)

[swift crag]

that means they're two different enum types

[timber tide]

assetpath is a string and that's kinda what I use

[swift crag]

you should just declare one enum type and use it in both places

[timber tide]

guid idea seems neat

[swift crag]

This breaks if you rearrange your assets

the GUID is nice because I can rename and move my assets without breaking existing save data

[verbal dome]

Yep

[timber tide]

I've it onvalidate

[swift crag]

Right, but existing save data now has the wrong asset path

The GUID is eternal.

(and fixed-size)

[verbal dome]

I also like to keep my OnValidate very lightweight or non existent

But sometimes its needed

[swift crag]

I'm not a huge fan of the giant pile of OnValidates, yeah

[timber tide]

yeaaah, something I was going to change eventually anyway

[swift crag]

I have another place where I can't really do that

I also use GUIDs to identify specific components in my prefabs

[zealous oxide]

ok this sounds like what i'm after

[swift crag]

I have to manually click a "generate GUID" button on those

I guess I could check if the guid is all-zeroes in OnValidate

[rich adder]

ah nvm..weird could've sworn this was visible in inspector for me

[verbal dome]

Can you give an example of this?

[rich adder]

:\

[atomic yew]

Hello, how can I activate an inactive object when I approach it with my character? without increasing fps?

[verbal dome]

Maybe in debug inspector

[swift crag]

    public abstract class Module : MonoBehaviour, IConfigurable
    {
        /// <summary>
        /// Uniquely identifies an instance of a module attached to an entity.
        /// </summary>
        [SerializeField] public Guid guid;

#if UNITY_EDITOR
        [ContextMenu("Regenerate GUID")]
        void NewGUID()
        {
            var so = new UnityEditor.SerializedObject(this);
            so.FindProperty(nameof(guid)).boxedValue = (Guid) System.Guid.NewGuid();
            so.ApplyModifiedProperties();
        }
#endif

[verbal dome]

Hmm or not

[swift crag]

I love casting from System.Guid to Guid

[languid spire]

inactive objects still fire Collisions and Triggers

[swift crag]

that's not very intuitive

[polar acorn]

OnTriggerEnter actually works on inactive objects for specifically this use case. It's a very unintuitive use case, but put a trigger on it and then you'll be able to put a script on it to enable itself when the player enters its trigger

[swift crag]

you mean disabled components?

[rich adder]

in debug mode it shows the field but its all 000s? wtf

[zealous oxide]

i dont think this was meant for me?

[swift crag]

an inactivated gameobject can't possibly collide

[swift crag]

It was not

wrong reply, my bad

was aiming at Osmal

[polar acorn]

It actually can and it's weird

Just triggers though

[verbal dome]

Really?

That sounds terrible

Are you sure you're not thinking of inactive components?

[languid spire]

no, it's Unity standard for waking up sleeping objects

[polar acorn]

You know what I might be, let me try testing it

[atomic yew]

I did not know that collision and trigger had this feature. Thank you very much for your answers.

[verbal dome]

It does say somewhere in the docs that it's meant for exactly what steve said

I can't find it

[atomic yew]

thank you too

[swift crag]

I am checking right now

[verbal dome]

something something in response to colisions

[swift crag]

Because this is true for disabled behaviours

Behaviours are disabled. Game objects are deactivated.

[swift crag]

yes, nothing happens

Disabled behaviours still receive a bunch of Unity messages

[polar acorn]

Okay, yeah, you guys are right, if the object is disabled, no message. But it does work on components that are disabled

[verbal dome]

Ah found it

Collision events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions.

https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html

[swift crag]

deactivated 😉

[steel smelt]

If you disable a GO in a physics callback or during a physics timestep, that GO can still be hit by physics queries until the actual update has happened

[swift crag]

it's useful to keep the terms separate to avoid confusion

[polar acorn]

Yeah, good point

[swift crag]

Collision messages are sent after the physics update

Oh, I misunderstood your message.

That's a corner case I haven't really looked into myself!

(I missed the "queries" word :p )

[steel smelt]

😄 Yeah it's a pain, it means you need to maintain the state and can't rely on object's active state for the hit logic

[verbal dome]

I guess disabling the collider is a safe choice then?

Or does that suffer from the same thing

[steel smelt]

I can't actually confirm that. I do not know. I maintain state for things that can only be hit once

[verbal dome]

I'll keep that in mind nevertheless - thanks

[rich adder]

hmmm not sure if its related, weird... unity lets you run methods on referenced script on disabled objects

[languid spire]

great name change, can any other foo please stand up and make themselves known

[verbal dome]

Yeah well in C#'s eyes they are still there like normal objects

[rich adder]

yeah thought unity would do some weirdness on disabled object, never had tried it. Good to know

[swift crag]

Yes. Unity has no power here.

That's an important thing to realize.

[languid spire]

generally the only things that don't run on a disabled object are Awake, OnEnable, Start, Update etc. The Events will all still be invoked

[swift crag]

Also, you can call methods all day on a destroyed Unity object

If you have a reference to a destroyed Unity object, you can do whatever you want with it

You will get errors if you try to use a Unity property.

[scarlet skiff]

is there a way to get the position of the where the middle of the camera is?

[rich adder]

ofc there is

[scarlet skiff]

or i suppose the cameras local 0, 0

[swift crag]

But beyond that, Unity can't "destroy" the actual C# object

[polar acorn]

camera.transform.position

[verbal dome]

I forgot, is an UnityEngine.Object == null when it's being destroyed?

[swift crag]

I forget if that's true during OnDestroy, etc.

[languid spire]

depends if you want world space or screen space

[swift crag]

The object compares equal to null, but that's just a trick. The reference remains.

[verbal dome]

In screen space or in world space?

[swift crag]

There is no 🥄

and there is no null

[verbal dome]

Camera.ViewportToWorldPoint(0.5f, 0.5f) is handy for screen space center

[scarlet skiff]

idk much about world space and screen space

[swift crag]

yes, Viewport space is resolution-independent, so it's easier to reason about

well, you'd better be ready to learn!

[languid spire]

time to learn

[rich adder]

screenspace is where your mouse cursor live, pixel coordinates.
worldspace is where gameobjects live

[timber tide]

https://learnopengl.com/Getting-started/Coordinate-Systems

that's a fun one

[verbal dome]

World space is 3D coordinates. Screen space is pixel coordinates (0->Screen.width, 0->Screen.height) or normalized coordinates (0->1, 0->1)

[swift crag]

• World space: a position from the point of view of the world. It is independent of your choice of parent.
• Local space: a position from the point of view of yourself
• Screen space: [0,0] to [width, height]. Z is the depth, measured in meters
• Viewport space: [0,0] to [1,1]. Z is the depth, measured in meters

[verbal dome]

Yeah that's a more valid explanation

[swift crag]

Your transform.localPosition is your position in your parent's local space

If you have no parent, then transform.position is transform.localPosition

[scarlet skiff]

so basically if a have a game where i move and the camera follows the player, even when going somewhere else, with screen space say, the bottom left corner would always be 0, 0?

[verbal dome]

Correct

[rich adder]

camfollow script? obligatory cinemachine

[scarlet skiff]

and world space is well, just the worlds cords independ on what goes on

[verbal dome]

And Camera class has methods to convert between world space, screen space and viewport coordinates

[atomic yew]

I cannot detect inactive objects with collision.

[polar acorn]

Yes, we found out I was a bit mistaken. It works on disabled components, but not on deactivated objects

[wind raptor]

Is one of these better than the other, performance wise? As in, is there a good reason to keep the buffer global (I do not need to track the buffer elements between function calls)

void doThing()
{
    byte[] buffer = new byte[1000];
    // do stuff with buffer
}

As opposed to

byte[] buffer = new byte[1000];
void doThing()
{
    // do stuff with buffer
}

[languid spire]

how often to you call doThing?

[swift crag]

The first one allocates every time you call doThing.

[verbal dome]

Do you call it often? Having it in the class (your second option) will allow you to not allocate a new array every time

Which would produce garbage

[atomic yew]

How can I detect it? Isn't there a method?

[swift crag]

I've gotten major GC reductions by moving a List<T> out of a method and into the class

[wind raptor]

Typically a few times a second, but it could go up to 20-100 times a second

[swift crag]

and just clearing it each time I need to use it

[polar acorn]

I think what you'll have to do is to make a second object with the trigger, and have that object enable the original one

[sharp wyvern]

this is the typical memory vs speed balance. which would you prefer?

[swift crag]

i wouldn't call this a tradeoff at all

[languid spire]

then declaring the array outside of the method will be much more performant

[swift crag]

unless this method is only ever called very very infrequently

[wind raptor]

Pretty frequently

Okay, thanks

[swift crag]

You'll be holding onto that array forever, sure, but holding onto memory is way better than allocating and freeing it over and over

[sharp wyvern]

either you have the memory allocated all the time, or you spend time allocating it each time.. how is that not a trade off?

[swift crag]

because garbage collection is a huge performance consideration

the time taken to allocate the array is secondary to all that trash you're producing

[sharp wyvern]

GC counts as "time"

[swift crag]

I'd say it's more memory-heavy to be producing garbage

it puts more pressure on the allocator

[languid spire]

this is game dev, when is speed ever a secondary consideration?

[verbal dome]

If you allocate a new one every frame time, you might be consuming more memory, right? If it is called often

[atomic yew]

I think I'll do that. Thank you very much for your answer. Good evening.

[verbal dome]

Since it stays in memory until it's collected

[swift crag]

until the GC cleans it up, yes

[sharp wyvern]

initialization

[timber tide]

my ide yells as me when I don't make nonalloc containers for casting each frame

so I must do what it says

[swift crag]

It's both slower and more abusive of your heap to allocate constantly

A temporary allocation only wins if the method is used so rarely that there are usually no allocations

[verbal dome]

Could always set the array to null when you know you won't use it in a while

[swift crag]

this does remind me of something

I have an AI planning system that generates a lot of garbage

[verbal dome]

Yeah, that kinda stuff tends to need a lot of lists etc

[swift crag]

It's doing A* and has to generate a bunch of nodes as it explores

When it's done, every single object it allocated is thrown out

I'd love to be able to put this all in a scratchpad that I dispose of at the end

[sharp wyvern]

use a pool?

[swift crag]

Yeah, I might just do object pooling.

Each state contains several hash sets to hold world-state

[wind raptor]

Secondary question. If I opt for a global, persistent array, are there any performance considerations (not memory, not too concerned about that in this instance) for grossly oversizing it? Making it 4000 bytes, say

[swift crag]

The objects the hash sets store are all value types

[swift crag]

I didn't see any obvious way to do this in regular C#

[languid spire]

no

[sharp wyvern]

size as power of 2 perhaps?

[wind raptor]

Why?

[swift crag]

I know that you can use a temp allocator with NativeArray, but that's not helpful here, since I'm using managed types

[swift crag]

When you run out of space, reallocate and double your capacity

This is basically what a List<T> does.

maybe you should just use a list!

[swift crag]

...well, actually...

[verbal dome]

I should probably start initializing certain lists with a capacity

[swift crag]

All of these hash sets and dictionaries are storing value types

[verbal dome]

If I know the approximate maximum items for them

[swift crag]

and those value types are storing primitives like float

[sharp wyvern]

this will force it internally to be exactly aligned in memory.. e.g. if your size is 4096 you can specify an index with exactly 3 bytes

[swift crag]

Maybe I can just allocate a big pile of NativeHashSet and NativeHashMap with the temporary allocator

at that point I might as well bite the bullet and completely Burst this thing

[stoic relic]

Is there anyone that can help me with a terrain generation script? (I'm new to unity and game dev in general so I'm not exactly sure what kinda questions to ask)

[outer cobalt]

if i stay still, everything is fine, then when i move the box colliders, rigidbody ect get set to None and it gives me the error Object reference not set to an instance of an object

[verbal dome]

Plenty of helpful people here, but we need a question to be able to answer

[outer cobalt]

code

Terrain generation is not exactly a beginner subject though, at least for your first game

Popularity of MineCraft etc got people thinking that it's easy I guess

okay bugfixing this myself (i am learning) it has to do with my Animator

[outer cobalt]

thanks! havent used discord before

[stoic relic]

cool - I had a terrain generation script working for a minecraft-esque game (I know - why the hell is a beginner working on this) and it worked on a single thread but had a level of detail system implemented where it merges blocks further away into a single bigger block. I've now tried to multi-thread this by using Burst and nativearrays and I currently have a single persistent array that's causing a leak but I can't exactly dispose of it at any given point.

[verbal dome]

Sounds like you have programming/C# experience?

I haven't really worked with Burst though - can't help with that, maybe someone else will

[stoic relic]

I've got tons of it but never in the gaming area - I work as an .NET dev otherwise for work

[verbal dome]

(Burst caused random crashing on my non-LTS unity, only took me 1 year to find the cause 🙃 )

[stoic relic]

that sounds like a wonderful time c':

I'm so sorry to hear that 🥲

[verbal dome]

Honestly you might as well ask in #archived-code-general

[outer cobalt]

would it be better if i handled animations in another function?

[stoic relic]

being upgraded as we speak Q_Q

[outer cobalt]

if isDev = #archived-code-general

[stoic relic]

if isDev && isBeginnerSupposedly is why I thought it was supposed to be here, but thanks!!

[outer cobalt]

isProfessionalWorkingDev = #archived-code-general

😉

[stoic relic]

I feel like such a noob when it comes to gameDev 🥲 - I've now jumped engines 3 times and barely progressed 😄

[verbal dome]

What engines did you try?

[stoic relic]

I went from godot to unity to unreal to unity - the order of progress made in each goes unreal > unity > godot

[verbal dome]

In any case having prior C#/.NET experience is a huge boost for a beginner

[stoic relic]

yeah - coding hasn't been too difficult of an issue. The terrain generation was entirely self-directed which I only recently realized was an impressive feat for beginners in the videogame world

[languid spire]

not at all, proc gen terrain is merely an experiment in array manipulation and reading the documentation

[outer cobalt]

when my animation changes, it gives me a Object reference not set to an instance of an object I referenced the anim and i did a getcomponent and it still doesnt work

[mortal bridge]

why does my saved animation conditions keep disappearing everytime I enter the project?

[outer cobalt]

the Animator is connected to the player

[languid spire]

did you check?

[outer cobalt]

and even in the start i did a anim = GetComponent<Animator>();

[rich adder]

like what ?

example

[mortal bridge]

I set bool and integer

I save it

I quit my project. Reenter. Boom gone

[rich adder]

strange..

are u in playmode changing ?

[languid spire]

showing the full error message and the code would help

[mortal bridge]

I am sorry I don't understand what this means

[outer cobalt]

one sec 🙂

[polar acorn]

what line

[mortal bridge]

Also

[outer cobalt]

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

[polar acorn]

What line

[outer cobalt]

122 and 107

error on top

[polar acorn]

By adding it to the top you've made the line numbers worthless, but I assume anim is null

[rich adder]

is the game runnig when you save those ?

[outer cobalt]

i've set the Anim in the Player Movement script itself to the playeranim

[languid spire]

lol, by adding the comments you screwed the line numbers

[mortal bridge]

Ahaha sir definietly not. If it were a problem that simple I would've solved it by now

[polar acorn]

Show the full inspector of this object

[outer cobalt]

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

[rich adder]

im still unsure where you are setting the bool or whatever

[outer cobalt]

is it not because im using multiple frames now due to using pixelart?

[polar acorn]

The full object's inspector. You can go ahead and collapse this one since it's quite big to show the rest of it

[polar acorn]

It is because anim is null

[outer cobalt]

how? i've set the anim

[polar acorn]

Send the full object's inspector and I'll see

[languid spire]

that is what we're trying to figure out

[mortal bridge]

by pressing that plus sign

[rich adder]

great Microsoft has renamed Bing Chat to Copilot .....

[languid spire]

probably just need to remove

anim = GetComponent<Animator>();

[polar acorn]

So, this object doesn't have an Animator on it

[outer cobalt]

But i set the animator?

[polar acorn]

That would be why anim is null because you're setting it to null in Start

[rich adder]

so the transition is changing itself ?

[mortal bridge]

yes

[languid spire]

yes, and then set it to null, see above

[polar acorn]

Yes, you set it to the Animator component on this object in Start. This object does not have an Animator so it sets anim to null

[mortal bridge]

I mean I have code for it but

it basically changes itself

code is an if staement so shouldnt matter its just for playing it

the conditions I set keep disappearing after I re enter my project its really frustrating

[outer cobalt]

i am so confused

[mortal bridge]

I had 2 for death. But when I reentered I saw that it didnt play then I checked everything for half an hour then saw that conditions was reset

[polar acorn]

What do you think this line does

[outer cobalt]

i removed that line

it still gives the same error

and now i set the anim in my script to the proper anim

[languid spire]

why, you set the Animator correctly in the inspector but set it incorrectly (to null) in Start. So just dont do it in Start like I said

[polar acorn]

Show the updated code, and the updated error

[outer cobalt]

hold up, its also giving me errors that my parameters do not exist lmfao?

[polar acorn]

Show updated code and new errors

[mortal bridge]

since you are helping the guy with animations can you help me too?

[outer cobalt]

https://www.toptal.com/developers/hastebin

NullReferenceException: Object reference not set to an instance of an object
PlayerMovement.updateAnimationParameters () (at Assets/Scripts/PlayerMovement.cs:121)
PlayerMovement.Update () (at Assets/Scripts/PlayerMovement.cs:106)
NullReferenceException: Object reference not set to an instance of an object
PlayerMovement.FixedUpdate () (at Assets/Scripts/PlayerMovement.cs:140)

its also weird that its not saying my parameters exist but i guess that because the script is still seeing it as "null?"

[polar acorn]

You have forgotten to include code in your code

[outer cobalt]

bruh i pasted it

[rich adder]

did u save ?

[verbal dome]

Flashbanged

[outer cobalt]

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

💀

[polar acorn]

anim is still null. You have at least one PlayerMovement without anim set

And also rb is null for the second error

[outer cobalt]

how is rb also null when i set it in the inspector

[mortal bridge]

@rich adderDo you have a solution?

[polar acorn]

Did you set it on every PlayerMovement

[verbal dome]

That definitely sounds unusual, not supposed to happen

They should save even in play mode

[devout flume]

When you build something, and then import it as a prefab: how can you check the components of that prefab, without having to place it back?

If you can't do that, what happens if you put the prefab in the hierarchy, modify its components, and place it back in the project assets, wouldn't it prompt issues with references you made?

[rocky canyon]

u can double click the prefab and it'll open the prefab in its own window

all references a prefab has should either be inside the prefab itself.. or they need to be assigned during runtime after the prefab is instantiated into the scene (using coding)

you can't use a reference to something in teh scene w/o the references having errors

[devout flume]

Ooh, makes sense now, thanks a lot
Actually I'm quite stupid, it works exactly like all the other things lmao

[rocky canyon]

no prob

[outer cobalt]

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

@polar acorn this never used to be a error, i copied it over from another object, i switched art styles and im now doing PixelArt which uses multiple frames, is it not because its switching frames it doesnt see the original RB or anim anymore?

[polar acorn]

The error is that anim and rb are null on at least one PlayerMovement component. This is abundantly clear from your errors

Find out where you have a PlayerMovement that is missing one or both of these assignments

[rich adder]

I was testing it but could not replicate it, youd have to maybe give more info on how its happening on your end

[polar acorn]

Errors do not lie. If the code says something's null there, something's null there. Check your own assumptions for why you think that can't be the case because it is always the human that is mistaken and never the error

[outer cobalt]

i dont see it hahahaha

[polar acorn]

First off, search for t: PlayerMovement in your scene. See all of the objects that have PlayerMovement. Check if any of them are missing assignments

only object with PlayerMovement is the player itself, i am checking the code rn

[queen adder]

https://hastebin.com/share/voxesadela.csharp
yo my code doesnt know what GetKeyDown is or what KeyCode is

the tutorial im following works but mine doesnt

[rocky canyon]

thats cuz its misspelled bro

[queen adder]

what

[rocky canyon]

check the code again

[outer cobalt]

typo

[queen adder]

alr hold on

[mortal bridge]

What do you want from me?

[rocky canyon]

and its odd that ur using a GetKeyDown for a mouse button..

[queen adder]

im following a tut idk anything about coding

hopefully i get better but rn idk anything

[rocky canyon]

normally you'd see GetMouseButtonDown

      if(Input.GetMouseButtonDown(0))
        {

        }```

[queen adder]

huh

[rocky canyon]

well ya, just check ur spelling

[queen adder]

might try that instead

[rocky canyon]

ur original code should be fine.. only its misspelled

[queen adder]

well it was spelling thank you

[rocky canyon]

c# is case sensitive

Update() is not update() etc

[mortal bridge]

wait

[rocky canyon]

you apparently dont have that variable

[rich adder]

ok

[mortal bridge]

I have this

sorry for deleting and reposting. I had to change some things

[polar acorn]

Check after starting the game, when the errors are present

[queen adder]

alr thank you for the help

[rocky canyon]

using a b d etc is confusing.. if you tend to share the code often try to use some better naming

[rich adder]

hmm changing it here will not affect the original Animator Controller

[mortal bridge]

exactly

[swift crag]

I cut my garbage by 90% by using Unity.Pools.GenericPool to pool my planner states (and by just clearing their collections instead of constructing new collections)

[mortal bridge]

It reset again

[swift crag]

very handy

[mortal bridge]

While I was in unity

[outer cobalt]

guess what

wasnt even that

[verbal dome]

Sounds good

[rich adder]

try to recreate a new controller ? I'm not sure why it would be happening, the controller is an asset so just chaning in editor would affect it unless u had code changing that somehow

[verbal dome]

I'm completely rewriting my AI currently 🫠

Well, the core of it

[swift crag]

yeah, that's what's going on here

[mortal bridge]

I actually only have 4 scripts. This is a new one Im practicing on. I can send you all if you want?

[swift crag]

I'm doing a GOAP ™️

so far the enemy can actually plan to move to the player and perform a multi-step attack

[rich adder]

im dreding goap rn 😭

[verbal dome]

I aim for that too

Any good learning resources? I kinda semi-freehanded it and never finished it

[mortal bridge]

note: my Unity version is the latest

[rich adder]

should not affect the asset :\

[broken trellis]

I hate compiler errors. I couldn't find the code unlocker, and had to delete my entire project

[mortal bridge]

maybe bugs?

[verbal dome]

I'm migrating to using purely data-based agents so that I can test their behaviour and cooperation in edit mode

[swift crag]

it can reason about:

• atomic facts (e.g. "I like making things unalive")
• entity facts (e.g. "The player is alive")
• entity proximity facts (e.g. "I want to be within 2 meters of the player")

One thing I can't do right now is delete facts. that's going to be exciting

[rocky canyon]

you should use LTS versions for the best support.. but yea probably doesn't matter what version you're using

[outer cobalt]

@polar acorn https://gyazo.com/259191b636bbc2dbdda7ec7ca309169e

[mortal bridge]

The animations were made in an older version but should work just fine.

[polar acorn]

"Code unlocker"?

[outer cobalt]

Turns out that it doesnt like me just replacing something straight up, i had to readd the sprite

[rich adder]

It should work fine then

[outer cobalt]

it was not seeing the player straight up

didnt have to do with the code

[swift crag]

I've been mostly inspired by these two things:

[mortal bridge]

You think this is worth a bug report?

If we can't fix it

[outer cobalt]

thank you guys for helping, learned lots, thanks for not just telling me the awnser

[rocky canyon]

if its a bug it'll probably have already been ticketed

[rich adder]

to know for sure if its a bug youd have to try it on another project /

[outer cobalt]

especially digi, thank you friend

[brave valve]

Hello, I have a problem.
I have a JSON like this:

{
users: [{...}, {...}]
}

Each of these objects in the array have this schema:

• name: string
• age: int
  Now I want to apply it to the class Users, so I did that:

struct User {
 public string name;
 public int age;
}

class GameData {
 public User[] users;
}

GameData game = JsonUtility.FromJson<GameData>(rawJson); // rawJson is the json in plain text

But now when I log game.users it returns null. Please help me 🙏

[swift crag]

The "aha" moment for me was realizing that A* doesn't need a fixed list of nodes. It just needs you to give it new nodes to explore!

[broken trellis]

Idk what it's called, but I got stuck with an error CS2012

[mortal bridge]

Well you just did and everything's fine.

[rocky canyon]

no.. you'd have to try your project

on a different version..

[rich adder]

u need to show the full context

[rocky canyon]

to rule out its not ur stuff

[verbal dome]

Thanks, saving those. The talk I've seen but I'll give it a rewatch.
Currently trying to decide on the arcitecture for group behaviours. It's complex as hell lol. Aiming for SWAT-style tactics etc.

[timid hinge]

Hi guys, sorry for being annoying, does anyone know how I can fit these dungeon rooms into just one square?

[broken trellis]

I read something about scripts getting "Locked" in VS Code

[timid hinge]

like this

[polar acorn]

What is the actual error

[swift crag]

F.E.A.R. just faked those

[rich adder]

No i meant with ur version

[mortal bridge]

Actually I used it in an older version way before already

[swift crag]

(we should chat more in #🤖┃ai-navigation since it's busy in here)

[broken trellis]

Lemme see if I can find it. As I said, I got pissed and deleted my project

[mortal bridge]

not my first time

[polar acorn]

Instead of doing that, you should just fix the problem

[broken trellis]

the requested operation cannot be performed on a file with a user-mapped section open

[polar acorn]

That doesn't sound like a compile error

[broken trellis]

Probably, but angry people do stupid things that they regret, and a I rgret throwing away that 4 hours of work.

please send it via link

I mainly came here to grieve the loss that I got throwing all that work away, but also hoping if the future that maybe I could get help with errors like this?

[mortal bridge]

Do you guys mind taking a look at my project?

[brave valve]

I don't understand, why? You can't understand the code like that?

[gray pond]

hi peeps, going through a C# tutorial rn to learn the language and i don't get the difference between float, double and decimal

would somebody mind explaining it to me like a 5 year old?

lol

[shell sorrel]

just use float

[rocky canyon]

as a beginner you'll probably be fine just knowing a float is a decimal

[shell sorrel]

the difference is how precise each one is and how much data it takes to store each one

[brave valve]

ok 👍

[rocky canyon]

all the other types are for more advanced things

[gray pond]

it's not about usage, i just don't really get it is all

ok no worries

[mortal bridge]

please

[shell sorrel]

unity uses float for pretty much everything, and rarely does double

[rocky canyon]

ya, just dont complicate things until a float no longer works for you

[gray pond]

gotcha

[shell sorrel]

same goes for short int long

just stick to int

[brave valve]

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

[gray pond]

idek what short or long is, they didn't mention it 💀

[rich adder]

also
and the data saves ok? is just not loading ?

[gray pond]

oh boy

[mortal bridge]

@gray pondjust be mindful about arrays when using float

[gray pond]

i'll learn eventually

[gray pond]

idk what an array is either yet 😭 sorry

[rocky canyon]

i dont think u can have an index of float..

[rich adder]

float point imprecision if number gets too big

[mortal bridge]

so if you have 3 game objects you can use int. for 1 2 3

[rich adder]

eg if your map is hugeeeeee

[brave valve]

no its ok

[rocky canyon]

0, 1, 2 * 😈

[brave valve]

everything else is fine

[mortal bridge]

damn yeah I still get confused about that

[rocky canyon]

lol no worries.. computers count from 0

[shell sorrel]

well, but yeah lets not go there, (screw you lua and matlab)

[rocky canyon]

lol.

[rich adder]

which one is the logging

game.users

[mortal bridge]

@gray pondarray is storage

easy

[brave valve]

void Start() {
        level = ReadLevelFile();
        levelName.text = level.name;

        Debug.Log(level.timeline) // <------- it logs null
    }

[mortal bridge]

so Is there a volunteer who would take a look at my project?

[shell sorrel]

well do you ever write to timeline

[brave valve]

but game.users was just a simplified version for the code on discord, level.timeline is the real full code

[shell sorrel]

its a list and those start as null unless you create one

[brave valve]

timeline is in the json

[slender nymph]

if you need help with something specific then ask a question
https://dontasktoask.com

[mortal bridge]

@slender nymphI already did. I think you come just now

[shell sorrel]

Element is not marked [Serializable]

[brave valve]

What do I need to change ?

[slender nymph]

then link to your question or repost it because i don't see it and i'm sure nobody else wants to scroll for several minutes just to find whatever it was you allegedly asked about

[rich adder]

add the attribute they sent

[shell sorrel]

add the attribute above it

[brave valve]

How do I mark [Serializable] on Element

oh ok

I'll try

[shell sorrel]

[Serializable]

[mortal bridge]

My animation conditions get deleted randomly. Navarone tried to replicate it but it worked just fine for him.

[shell sorrel]

put it above all the structs and classes you are using with JsonUtility

[rich adder]

are you sure you dont have a another script changing the Animator Controller somehow?

[mortal bridge]

Yes. I can send you all my 4 scripts if you want

[rocky canyon]

4 scripts all modifying 1 animator controller? 👀

[rich adder]

not the SetBool stuff, I mean modifying transitions

[mortal bridge]

I don't have

[shell sorrel]

sounds over complicated with 4 things modifing the same controller

[mortal bridge]

1 for animator

3 for other things

[shell sorrel]

feel like i would have one component interacting with the animator that other things call on to do work

[rocky canyon]

disable the script thats modifying the animator and see if u still have issues? that would eliminate the script as the culprit?

[mortal bridge]

Already tried that.

[rocky canyon]

and wat was the outcome?

did it still have problems?

or did the problems dissapear

[brave valve]

[Serializable] public struct Element {

-> Assets/Scripts/GameStart.cs(8,2): error CS0246: The type or namespace name 'Serializable' could not be found (are you missing a using directive or an assembly reference?)

[mortal bridge]

Yes. I wouldn't be here otherwise

[rich adder]

System

[shell sorrel]

using System; at the top

[mortal bridge]

I don't think it has something to do with the script

[brave valve]

ok thanks 🙂

[rich adder]

so is it only on this project? i dont recall if you answered this

[rocky canyon]

then its probably #🏃┃animation issue, if its not the script

[mortal bridge]

Well if you could take a look at my project I'd appreciate it

[mortal bridge]

I did answer.

I tried it in an older version way before

It worked fine

[rocky canyon]

then your solution may be to use a different version

[rich adder]

before is not now though 😛

[brave valve]

It's working now! Thanks @rich adder and @shell sorrel for the help 🙂

[rocky canyon]

ya, i wanna guess that you've added to ur project since then...

u cant use that as a comparison if its not exactly how it is now

[raven hill]

Does anyone understand why my player doesn't jump?

[rich adder]

maybe something is messing with the isDirty or something

idk much about editor stuff though

[rich adder]

ofc velocity ovverrides any Forces also ur missing Impulse

[mortal bridge]

Well will try that than I guess nothing else we can do

[raven hill]

Ah yes

thx

[rich adder]

oh wait i see you do have rigidbody.velocity.y so thats fine

I think if you add Impulse it will work

[mortal bridge]

maybe if you guys took a look at my project but... anyways

[rich adder]

I cant rn Im at work

[raven hill]

It dont

[rocky canyon]

still tho.. yea the force is still being interrupted

impulse might fix it

[brave valve]

@rich adder just last question: why [Serializable] resolved the problem? Because I put that but I don't know why...

[rich adder]

Unity needs it to serialize the class/struct

[mortal bridge]

okay. can you let me know when you get home?

[shell sorrel]

it tells unity its aloud to serialize this type

[brave valve]

ok, thanks

[rich adder]

sure!

[rocky canyon]

thats a big ask.. ive never seen anyone want to download random peoples projects.

[rich adder]

serializing is just a fancy word for saving data in a structured way

[mortal bridge]

I know. I wouldn't really ask it if we could fix it somehow

[rocky canyon]

not saying ur a scammer or anything.. but it happens and people are hesitant to do it

[rocky canyon]

export ur stuff as a unity package and pull it into a different version

that'd be my suggestion

[mortal bridge]

well yeah I am a scammer you got me! Hello this is Unity tech support how may I assist you today?

[rocky canyon]

since u said it works in another version. that might be the only thing u can do..

or in the unity hub u can swap the version ur using to open it

that'd be the easiest way

duplicate the project folder first so if things go bad ur project isnt ruined..
and with the new project just open it with a diff version

[rich adder]

tbh testing the same project (a copy) on a different unity version is your best sensible bet rn @mortal bridge

[rocky canyon]

mmhmm.. and if it works in that new version.. then u can send in a bug report

if u believe its the version thats bugged (which if it works on a different version may very well be the case)

but like nav said, a copy of this most recent version..

not the older version u said worked b4

[mortal bridge]

Okay. I have big concerns about version change since some of my shaders were ruined but let me do it. You guys make me face one of my biggest fears

yeah a copy

yes a copy i can do it

[rich adder]

You should always do it on copies, and regardless You shouldprob have GIT setup with repo

[iron mango]

hey! what is the best way to create health bars for enemies? what i mean is, to show the healthbars on screen, you first have to identify that they are visible on screen. i think to constantly loop through all enemies is not it xD

I am very proud to announce that when I tried this in the earlier version I used to work with it worked (at least for now I quit and reentered it was fine) I am proud to be one of the bug finders

[rich adder]

so its only broken on ur version of Unity and which version is that?

[mortal bridge]

latest

[rich adder]

latest isnt a version

[mortal bridge]

two thousand twenty two. three. nineteenf one

2022.3.19f1

[rich adder]

not the latest 😛

but yeah sure

i never use "the latest"

always find weird bugs

[mortal bridge]

they be updating quick

[rich adder]

they better be

its LTS

[mortal bridge]

time to report some bugs baby. better reward me for it. like dont get revenue share or money per install from me

check the layer order anyway

[slender nymph]

it's also clearly not disappeared. it's most likely behind some other object, like your background

using System.Collections.Generic;

public class MonkeyScript : MonoBehaviour
{
    float targetPositionX;
    [SerializeField] private float speed;

    // Start is called before the first frame update

    }
}```

[rich adder]

is the background a sprite? check the Z pos is > 0

its probably the Order layer though

[zealous oxide]

hey friends, i'm still stuck on my enum issue from earlier. i've got 2 classes with an identical declared (within each class) enum and I want 1 class to set the enum on the other class to match whats in the first one without having to write out each individual change, so it would be more like "spawnedDotZonePrefab.GetComponent<AOEDamageScript>().debuffType = this.DOTZoneControllerScript.debuffType;" but ofc this code doesnt work and i'm not sure what it is exactly i'm looking to type in here for the bit after =

[rich adder]

why not just make a property that Invokes an event when changed

and have other enum class listen to it

public MyEnum MyEnumValue
    {
        get { return _myEnumValue; }
        set
        {
            if (_myEnumValue != value)
            {
                _myEnumValue = value;
                OnMyEnumValueChanged?.Invoke(value);
            }
        }
    }

[raven hill]

It works now, thx

[zealous oxide]

interesting, this seems to be getting a bit far ahead of what i currently know.

[buoyant knot]

that’s why he is explaining it to you

[rich adder]

properties are ez, they are just fancy methods

but they run everytime you access the prop

[buoyant knot]

you need to understand properties to use C# anyway

it’s a core part of the language

[quick pollen]

so I have this

i wrote this to experiment with something

and for some reason in the inspector, the value of landed is flickering??

[buoyant knot]

maybe isGrounded is flickering

[rich adder]

yeah if you're using the CC grounded then its total shite

[buoyant knot]

this is another situation where I would use a property and not a field

[quick pollen]

thats so bad

what I want basically

[rich adder]

I would make my own grounding

[signal cosmos]

pls review guys, and how to improve, sry for my en:
https://gdl.space/olejitobop.cs

[rich adder]

like Sphercast or whatever

[wintry quarry]

why not just:

landed = _controller.isGrounded;```?

but yeah CC.isGrounded isn't the best.

[quick pollen]

i was testing something so the code is shit

[buoyant knot]

public bool Landed => !_controller.isGrounded;

[quick pollen]

what I want is to not be able to bhop

like basically whenever I land on the ground

I want the "Jumping" input axis to be reset somehow

[rich adder]

if it works dont worry about it

[wintry quarry]

I mean yeah this is expected of CC.isGrounded

use your own grounded check

[quick pollen]

otherwise it works fine

[wintry quarry]

CC.isGrounded is only true when your last CC.Move call pushed it into the ground

this trips people up all the time

[buoyant knot]

use your own grounded check

[quick pollen]

dang thats stupid

[mortal bridge]

indeed

[rich adder]

its meant for basic usecases

[polar acorn]

When using a character controller, it is important to include a small amount of downward motion, even when grounded, so that you continue to be in contact with the ground

[quick pollen]

like it works thats not the issue

[buoyant knot]

i feel like I have to repeat his advice because it is not heeded

[rich adder]

like SimpleMove method which uses gravity, but really who uses that 😂

[mortal bridge]

first time hearing

[rich adder]

flicker is very common tbh esp on things like slopes

[signal cosmos]

my english its bad but, ok if i understand what you say now, its ok this version, how improve if its possible, exiting other methods more great?

[buoyant knot]

code with big documentation

[rich adder]

Im just saying If its working fine, the code doesnt need to be refactored unless you dont understand it easily

[buoyant knot]

comments go big big

[quick pollen]

can someone help with this?

[median ruin]

What does this mean... I literally pulled the script to the gameObject?

[quick pollen]

i know theres a function to reset all input axises

which would actually be good

[rich adder]

the last sentence is very important

[buoyant knot]

///<summary>Docstring </summary>

[median ruin]

Name and class name match

[final kestrel]

How often do you guys implement the observer pattern in your codes?

[rich adder]

then you have compile errors

[polar acorn]

Make sure that there are no compile errors and that the file name and class name match.

[rich adder]

I use events almost all the time

so yeah every project lol

[buoyant knot]

i spam events a lot

like, a lot a lot

[quick pollen]

whoops

[median ruin]

it just says that it doesn't exist?

[verbal dome]

Events are good, just gotta remember to unsubscribe if needed

[rich adder]

honestly after you get a hang of events you never want to go back

[buoyant knot]

that’s just part of the workflow

[polar acorn]

So go find whatever component is missing a script and remove it

[signal cosmos]

well, I wrote this code, I understand it, and I'm thinking if this method of saving data is good..., maybe there is something faster, you understand what I mean, I'm not experienced in unity c#, sorry if I ask

[verbal dome]

They seemed a bit intimidating at first, but they really aren't

[final kestrel]

Ah okay thanks for the answers.

[buoyant knot]

events are an easy way to satisfy the open/closed principle

[broken trellis]

{
if(Input.GetMouseButtonDown(0))
{
target = Camera.main.ScreenToWorldPoint(Input.mousePosition);
target.z = transform.position.z;
}
}

Newby here. Any quick way to make this a core routine?

[buoyant knot]

what is a core routine

[final kestrel]

I am then making it my priority to learn now.

[rich adder]

looks perfectly fine to me 🤷‍♂️

[verbal dome]

Why do you need a coroutine? Do you need it to move over time?

[signal cosmos]

thx, you are good people

[buoyant knot]

public event Action MyEvent; is the most common

delegates can get complicated. Actions are simpleish

[broken trellis]

I'm making a click and point grid movement system for a turn based game.

[quick pollen]

why cant i cast a bool to be an int like this?

[median ruin]

Where do you use events?

[rich adder]

thats now how you cast

(int)

[polar acorn]

Because int is not a function

[verbal dome]

It would be (int) thing, not the other way around

[quick pollen]

oh im stupid

[verbal dome]

But you can't cast a bool to int

[quick pollen]

right

thanks

wtf why

[quick pollen]

why can't it be a 0 or 1

like in c++

[final kestrel]

It is kind of hard to wrap my head around events. I watch videos I understand why but never done it myself yet. I wondered if it is widely used.

[rich adder]

just make ur own function that does it

[verbal dome]

🤷‍♂️ You can do int myInt = myBool ? 1 : 0

[quick pollen]

true

I just didnt wanna resort to ternary operator

[rich adder]

thats like saying "i dont want to resort to if else statement"

[quick pollen]

it just looks funky in my line of code

[verbal dome]

Alternatively a function int BoolToInt(bool b) or something

But seems excessive iIMO

[buoyant knot]

Let’s say I am loading a level file. My SaveHandler class will invoke an event OnLevelLoad to call anything that needs to be called when a level has just been loaded.

[mortal bridge]

imagine doing that

only madmans do that

[rich adder]

regardless you still need return the if else no ?

[buoyant knot]

Or SpawnedEntityHandler invokes OnEntityDeath to call anything that must be called when a given entity dies

[quick pollen]

i mean its not the main thing

my main problem rn is the bhopping

[broken trellis]

How would you suggest I go about using the the mouse to move different object on a grid? I'm currently frankenstiening two tutorials together for a grid movement and a point to move tutorial lol. I'm probably gonna look for a tutorial for separate object selection for movement in a moment.

[buoyant knot]

Or PlayerMovement invokes OnPlayerJump to let anything know that the player has just jumped.

[quick pollen]

because i dont want it to be able to bhop

how could I fix that?

[verbal dome]

Bunny hop?

[buoyant knot]

back hop?

[summer stump]

Misspelled for bop i think

[median ruin]

hmm okay

[buoyant knot]

big hop?

[polar acorn]

That's usually a sign you're doing something odd the code is trying to disincentivize by making awkward

[quick pollen]

bunnyhop yeah

continuous jumping

[verbal dome]

Zero context here lol

[earnest atlas]

depending how you detect if jump is pressed or not]

[quick pollen]

i have a video above

which explains it

[dense cypress]

https://gdl.space/vebofequju.cs

First person player controller, except for whatever reason W and D move me one direction (not relative to player) and A and S the other

[quick pollen]

but ill re-record it then

[verbal dome]

Here

[buoyant knot]

generally, when a class does something that might cause other things to need to happen, BUT this class isn’t actually responsible for doing any of those things, you want to use an event

[verbal dome]

How exactly do you define bunnyhopping here

What do you not want to happen?

[buoyant knot]

wtf is a bunny hop

[median ruin]

I just use functions that call on each other

[shell sorrel]

its a quake / gold src thing

[verbal dome]

Jumping again right after landing which often leads to bigger jumps as a game mechanic

[final kestrel]

So, when I trigger the exit. The exit fires off an event and the scenemanager subscribes then loads the next level?

[mortal bridge]

dont change movedir vectorx z with input

[quick pollen]

if you hold down jump, the character can just keep on jumping

i want it to have a small cooldown whenever it lands

[earnest atlas]

How do you handle detection if a button is pressed?

[summer stump]

So nothing like the classic bunny hop from quake

[polar acorn]

So instead of checking for button held, check if the button is pressed

[earnest atlas]

New system or old?

[dense cypress]

how else?

[quick pollen]

old input system

[buoyant knot]

do you mean a buffer jump or double jump?

[mortal bridge]

what?

[shell sorrel]

oh because you called it that thought he was talking about quake/source stuff

[quick pollen]

        if (Input.GetAxis("Jump") >= 1 && jumpTime > 0f && Input.GetAxisRaw("Horizontal") != 0)
        {
            isJumping = true;
            gravPull.y = Mathf.Sqrt(_jumpHeight * _gravity * -10f);
            jumpTime -= Time.deltaTime;
        }```

[buoyant knot]

i think he means double jumps

[verbal dome]

This why I was asking to make sure heh

[polar acorn]

Why is "Jump" an axis

[dense cypress]

how else can I change the vector

[quick pollen]

i literally just explained it and provided a video

[summer stump]

No, because it is on the ground, not the air

[verbal dome]

Double jump implies jumping in the air. Here they jump as soon as they land

[quick pollen]

because I wanted to make it so u have to hold down the jump button for like half a second before it jumps, as a windup

[mortal bridge]

Ill write you some codes wait a sec

[shell sorrel]

jumo should not be a axis

use Input.GetButtonDown for it

[buoyant knot]

i just see some random jumping bro

[earnest atlas]

you can probably have bool that saves if jump was pressed and if jump is pressed and that value is too return instead of doing jump code.
when jump is not pressed just set the JumpPressed value to false back

[quick pollen]

then text after it explaining

[polar acorn]

That sounds like not the right way to do that

This is trying to use a hammer on a screw

[summer stump]

They want to HOLD jump, and when they land there is a cooldown before jumping again.
Right Alfy?

[polar acorn]

it's just not the tool for that

[quick pollen]

yeah

[shell sorrel]

so on becoming grounded start a timer

[buoyant knot]

oh i see now. that’s an issue with your input system, fam

[quick pollen]

well the old input system has the whole Sensitivity thing

and i thought itd be useful

so i dont have to write fucked up code

[earnest atlas]

old system is fine

[summer stump]

What sensitivity thing?

[buoyant knot]

i’ve never heard it called a bunny hop, since idk of any games that actually want you to continuously jump by holding jump. I’ve seen it before, but I don’t think it is intentional.

you should be using the new input system, with invokes events on button presses

[quick pollen]

basically we know that the old input system just interpolates between 0 and 1 whenever hold down a key
sensitivity is for telling it how long it takes for it to go from 0 to 1

[verbal dome]

AFAIK It's not usually a button hold but a button press instead

But I might be wrong

[quick pollen]

one time it broke an entire project because i installed it

and I was shamed for trying to use it and was asked why didnt i use the old one

[summer stump]

Wrong. That is not always the case. It is for GetAxis, but not GetButton

[earnest atlas]

cause its really different from old one

[mortal bridge]

float moveX = 0;
float moveZ = 0;

if (Input.GetKey(KeyCode.W)) moveX = moveX+ 1;
if (Input.GetKey(KeyCode.S)) moveX = moveX- 1;
if (Input.GetKey(KeyCode.A)) moveZ = moveZ- 1;
if (Input.GetKey(KeyCode.D)) moveZ = moveZ+ 1;
moveDir = transform.forward * moveX + transform.right * moveZ;
@dense cypress

[quick pollen]

and im using getaxis, yeh

[buoyant knot]

it should not break anything by installing it

[verbal dome]

That's messed up, use whichever you like

[quick pollen]

it straight up stopped processing inputs last time and I got a shit ton of file errors

[buoyant knot]

it should be simple to slowly transition, replacing calls to the old input system with calls to the new input system

[verbal dome]

If you got errors i'm sure those are fixable

[summer stump]

Use Old input. No need for new unless you want jt

[quick pollen]

the errors weren't in my monoscripts

[buoyant knot]

yeah, that is not normal behaviour

[verbal dome]

Tbh I never fully migrated to the new system. I mix both

[buoyant knot]

again, this is not normal

[quick pollen]

yeahh i could tell

[mortal bridge]

@dense cypressThis solved it?

[quick pollen]

so my experiences with it are bad

[summer stump]

I DO use new entirely, but both are perfectly fine

[earnest atlas]

mixing both will make so new one will work funiky

[quick pollen]

and I understand the old system much better anyway

[buoyant knot]

adding the plugin should not break anything

[dense cypress]

I'm just putting it in

[summer stump]

Now this is straight wrong
New is more performant
More flexible
And imo easier to use

[mortal bridge]

okay

[quick pollen]

best part is i couldnt even remove it

[earnest atlas]

New one is much better

[mortal bridge]

you want with what lines to replace these right?

[quick pollen]

tf
I said I understand it better
not that its better

[timber tide]

new one sucks for mouse so I use both

[buoyant knot]

pretty sure that is also not a real thing. it is just a package, and the package can be uninstalled

[summer stump]

Ah, misread, sorry

[quick pollen]

all good :)

[verbal dome]

I did too lol

[quick pollen]

i know its probably better

[buoyant knot]

idk wtf you did. are you sure you used the Unity input system package?

[quick pollen]

lemme rephrase
"I have a better understanding of the old system anyways"

[quick pollen]

yeah

but it doesnt matter anyway

[buoyant knot]

you should try to get it working, dude

it will make your life easier

[quick pollen]

there was no uninstall button

it overwrote the old one

[buoyant knot]

inputsystem does not overwrite the old input system

[quick pollen]

well idk wtf was up with it

but I spent like 2 days trying to fix it back then

and ended up having to create a new project

[buoyant knot]

back everything up, and try again

[earnest atlas]

I have no idea how he broke everything with unity import

[buoyant knot]

i honestly doubt it. it is a package

[earnest atlas]

I bet he never opened systemEvent

[quick pollen]

tbf me neither but i cant say im surprised

[dense cypress]

It works and they go in different directions but how do I make it relative to the player? and also the player does not stop moving at any point

[quick pollen]

anyhow

im really not sure how to go about fixing it

I was thinking of adding it as a feature

[mortal bridge]

relative to player that code does it alright already

[quick pollen]

that u can keep on jumping without cooldown

[mortal bridge]

try resetting movedirection

[quick pollen]

but ofc add a stamina requirement and when ur stamina hits 0 u cant jump anymore

[earnest atlas]

a while ago I said you how to fix it

[quick pollen]

but it still looks really weird

[mortal bridge]

you sure you put them in right places? show me the code @dense cypress

[quick pollen]

sorry i missed it

[dense cypress]

https://gdl.space/notudukecu.cs

[earnest atlas]

same jump into bool variable

[quick pollen]

the problem isn't with the windup thing

[earnest atlas]

on running jump code set another variable of "have jumped"

[mortal bridge]

yeaah I see

[earnest atlas]

and just run the jump code of
_isJumping&&!_hasJumped

[quick pollen]

like all of this could be fixed if unity had a function for resetting the value of an Axis

[earnest atlas]

nothing stops you from just editing it in runtime

[verbal dome]

Fixing what? The ability to instantly jump again when landing?

[quick pollen]

the value of an input axis? how?

[quick pollen]

rn we talking about it yeah

[earnest atlas]

if I remember it should be Vector3

just set y to 0

[quick pollen]

it has {get; private set} no?

and its not a vector3 its a float between -1 and 1

[verbal dome]

But you were answered already, what's wrong with using a cooldown/timer?

[earnest atlas]

you dont need to edit the INPUT

you can save the input

and edit it

[quick pollen]

the fact that I use the sensitivity thing in the inputsystem
so what it'd do is once the cooldown is over after a jump, it immediately gets flung into the air without windup

[quick pollen]

ohh I get what you mean

but like

[verbal dome]

Don't use GetAxis for jump input, why not just use GetKey

I don't see why you want 'sensitivity' here

[quick pollen]

because, as I explained it, I have a windup

[verbal dome]

Like a delay before you jump?

[quick pollen]

yeah

so u dont just immediately jump

[mortal bridge]

for update you go brr:
if (!IsOwner) return;
moveDir = Vector3.zero;
if (Input.GetKey(KeyCode.W)) moveDir = transform.forward+transform.forward;
if (Input.GetKey(KeyCode.S)) moveDir = transform.forward-transform.forward;
if (Input.GetKey(KeyCode.A)) moveDir = transform.right-transform.right;
if (Input.GetKey(KeyCode.D)) moveDir = transform.right+transform.right
moveDir.Normalize();

for fixxxxed update you go:
if (!IsOwner || moveDir.magnitude = 0)
{
m_Rigidbody.velocity = Vector3.zero;
return;
}
m_Rigidbody.AddForce(moveDir * moveSpeed * 25f, ForceMode.Force);

[quick pollen]

i dont want to have 3 different timers

[quick pollen]

ig ill rewrite everything then in jump

[dense cypress]

yep putting it in now

[quick pollen]

cuz most of it wont work using that

[mortal bridge]

dont forget double equal

yep

[mortal bridge]

work?

How would I make it so the distance between the mouse and the player doesn't affect the projectile's speed? I've been trying to figure it out but can't. In the clip you can see that the bullet is a lot faster when your mouse is far away while you shoot and really slow when it's close
https://gyazo.com/9a5a15373234c6f4f58aed3925c7d2ee

private void shootBullet()
{
    if (onShootCooldown) return;
    onShootCooldown = true;
    Invoke(nameof(removeShootCooldown), shootCooldown);

    var currentPlayerPos = gameObject.transform.position;
    var newBullet = Instantiate(bulletPrefab, currentPlayerPos - Vector3.back, new Quaternion(0, 0, 0, 0), null);
    var bulletRigidBody = newBullet.GetComponent<Rigidbody2D>();

    var mousePosition = Input.mousePosition;
    mousePosition = mainCamera.ScreenToWorldPoint(mousePosition);

    var bulletDirection = mousePosition - currentPlayerPos;
    bulletDirection.Normalize();
    bulletRigidBody.AddForce(bulletDirection * 20, ForceMode2D.Impulse);
}

[dense cypress]

exclusively W and D inputs work

[summer stump]

Jumping should be fairly separate from input, so I'm not sure what you're having to rewrite

[mortal bridge]

nice

just remove the moveX and moveZ and directly update the moveDir based on the key pressed and add a line to normalize moveDir after every inputs done

that should do it

[dense cypress]

how do I directly update the moveDir based on the key pressed

[vague dirge]

Hello, I have a question, what does transform.eulerAngle.y exactly do ? Like I know we get a rotation from the Y axis, but starting from where ? Because if we want a rotation, we need and axis (Y) an "end position", but also a "strat position" (= 0°), and what is it in this method ? Because I want to generalize it from an given vector axis and I'm planning to do that through Vector.SignedAngle(), but I dont know what to put in the from and to parameters. Thanks !

[polar acorn]

It gets the Y value of a Vector3 representing the object's orientation

[mortal bridge]

my man actually you need to learn it. If I give you codes nonstop you wont learn

[polar acorn]

Euler Angles are Vector3s that represent a Quaternion in the form of degrees about each axis

[swift crag]

Euler angles represent a rotation as three angles around three axes.

https://en.wikipedia.org/wiki/Euler_angles

[mortal bridge]

@dense cypressyou want resources?

[timber tide]

code seems fine as the direction is normalized, so the only thing I can think of is there's forces on the z, but it's 2D rigidbody. Debug the values just to make sure.

[dense cypress]

Imma try my best to figure it out but yes probably

[swift crag]

this gif will probably get obliterated by dyno, but let's try

https://upload.wikimedia.org/wikipedia/commons/8/85/Euler2a.gif

sweet

oh you know what

this actually makes a lot more sense to me now

[timber tide]

friendship ended with euler, quaternions my new bff

[quick pollen]

this gimbal lock or what

[mortal bridge]

Actually I just realized that you dont need resources for this. You can do it with your current knowledge

[swift crag]

no, it's just a demonstration of euler angles

[dense cypress]

speaking of which I did it, thanks for the help!

[swift crag]

each rotation uses the new axis, not the original axis

[verbal dome]

It's good to know the order that euler rotations are applied in

[mortal bridge]

it works the way you want?

[verbal dome]

Z, X, Y right?

[timber tide]

oh, there's an order?

[dense cypress]

yep (except for the fact that only the camera rotates and I wanted that for the player but I can fix that myself)

[mortal bridge]

very good. glad to be helpful

[timber tide]

Why doesn't the method work like angleaxis then. Would probably solve some gimbal issues.

[verbal dome]

Euler angles can represent a three dimensional rotation by performing three separate rotations around individual axes. In Unity these rotations are performed around the Z axis, the X axis, and the Y axis, in that order.
https://docs.unity3d.com/ScriptReference/Transform-eulerAngles.html

[timber tide]

that's such an odd ordering

[verbal dome]

It sounds odd at first, but it kinda makes sense to me

I can't explain why though 😄

I'm just used to Y being the 'parent axis'

And X is the child of that, and Z is the child of X

[gray pond]

when i click on a letter, it highlights white and then when i try to type to put a bracket or something between it deletes whatever's highlighted

what do

[timber tide]

I just know that in fps games you're usually rotating z -> y -> x (xyz) ordering

[verbal dome]

Press Insert on your keyboard

programming is like walking with no legs. first you gotta analyze the problem (you have no legs) then you should ask for legs from government (in this case me) (lets say they didnt give you legs) then you have to understand where to find legs and finally find legs and walk (problem solved) happy learning
