[rocky jackal]

so i could just use that instead of the normal ?

[hard viper]

not exactly, but you can definitely use this information especially to figure out where on the collider you should count as being

again: .Distance can tell you if mario should count as being on top of the goomba or at its side

so if you need to know if the monkey hand is supposed to be gripping a ledge, that is a good use case for calculating penetration

.Distance also gives you a unique point of the colliders along that line that would be in contact once displaced

[rocky jackal]

i dont think you understood what im trying to do

isnt vector3.idtance just the distance between two points ?

[hard viper]

i’m talking about Collider2D.Distance, which is equiv to Physics.ComputePenetration

Collider2D.Distance has absolutely nothing to do with Vector2.Distance and Vector3.Distance

Collider2D.Distance and Physics.ComputePenetration take in two colliders, and output the minimal translation vector to get them to be in contact exactly.

unlike contact points, these two methods (for 2D and 3D respectively) give a unique vector and point of contact to work with

you need to generate a unique result (ONE normal) to work with. And it needs to be an actual normal on the shape.

Hi, I have a project in Unity 2022.2.6f1 . I am trying to make a Roslyn DiagnosticAnalyzer work with additional .resx files. I was advised to provide those in our csc.rsp file since the project has multiple .csproj files, in the form of -additionalfile:"Assets/path/to/the/file.resx". However, if I do this, while there are no compile errors according to Unity and the analyzer does work on the codebase, somehow no scripts are attached to any prefabs or scenes anymore. Any advise? (not sure if this belongs here, or in #archived-code-advanced, or somewhere else )

The worm wiggle

My magazine and gun both have rigidbodies on them and that is clearly causing problems
I was hoping making them kinematic would make them play nice but..
I don't want to use layers to fix it. How else?

[leaden ice]

are you mixing Rigidbody and non-Rigidbody movement?

[dense tapir]

maybe you should turn the "discrete" to "continous" collision detection..?

[runic nimbus]

..yeah. The magazine is supposed to be adjusting itself to the magwell in Update() and onBeforeUpdate

Yet it stays in the same spot, strangely

[runic nimbus]

I do the same thing for the gun onto the hand position, but clearly the rigidbodies here are messing it up

[leaden ice]

This is your problem

don't mix physics/non physics motion

When you put the mag in the gun, make the rigidbody kinematic

[runic nimbus]

It is.

That's why it doesn't fall

if I make it physical, both objects do the worm wiggle

[craggy breach]

hello. how get how many pixel is visible in sprite? im using masks and need the visible pixels percentage

int totalPixels = image.GetComponent<SpriteRenderer>().sprite.texture.width * image.GetComponent<SpriteRenderer>().sprite.texture.height;
Texture2D maskTexture = image.GetComponent<SpriteRenderer>().sprite.texture;
Color[] maskPixels = maskTexture.GetPixels();
for (int i = 0; i < totalPixels; i++)
{
if (maskPixels[i].a > 0)
maskedPixels += 1;
}
print((float)maskedPixels / (float)totalPixels * 100f);

im using this now but not work

it would be kinda complex. You'd have to find the areas of the screen in which they overlap and then check the mask alpha (against mask threshold) at each pixel only in the overlapping area

also pixels in the sprites don't correspond to pixels on screen

It would be better probably to do this with a shader

output a texture and count the white pixels for example

hey guys?

my PlayerStats and Experience is finish now...
but now iam tested it inGame...it works fine, but have a little issue:

if there added in short time XP...then the calculator dont work correctly...

he use then the current value from this add, not the target value from last add...
(if i wait to finish the last add, then it works fine)

Hi. I want to make a card game. The properties of each card is stored in a scriptable object. I want to attach the abilities there as well but I can't attach scripts. Is there a workaround for this?
The Scriptable Object:

using System;
using Unity.Netcode;
using UnityEditor;
using UnityEngine;


public class ScriptableObjectIdAttribute : PropertyAttribute { }

[CreateAssetMenu(fileName = "New card", menuName ="Card")]
public class Card : ScriptableObject
{
    public string cardName;
    public string ability;

    public Sprite art;

    public int cost;
    public int power;


}

[dense tapir]

well, maybe i should say that i add the XP as float time

[dense tapir]

so you want to attach the scripts to the cards in inspector?

[clear halo]

yes

[dense tapir]

whait a second, i haved this problem in past too, i look how i have solve it

[leaden ice]

wdym by "attach scripts"?

You mean MonoBehaviours?

Those can only be attached to GameObjects

[dense tapir]

public List<string> additionalScriptNames; // Liste der Namen der zusätzlichen Skripte

// Zusätzliche Skripte hinzufügen
            foreach (string scriptName in additionalScriptNames)
            {
                Type scriptType = Type.GetType(scriptName);
                if (scriptType != null && typeof(MonoBehaviour).IsAssignableFrom(scriptType))
                {
                    enemy.AddComponent(scriptType);
                }
                else
                {
                    Debug.LogWarning("Skript \"" + scriptName + "\" wurde nicht gefunden oder ist keine MonoBehaviour-Klasse.");
                }
            }

[spring creek]

Backticks, not apostrophes

```

[clear halo]

I want to be able to drag a script there like I can with the sprite and make a function that adds that script to the gameobject when it is spawned

[dense tapir]

with that you have in inspector a string list, there you can write the name of your script what need attached...
(just the name, not .cs)

[leaden ice]

Not really possible. You could make a prefab and reference the prefab here

then instantiate the prefab as a child

[dense tapir]

thats true

[clear halo]

I will try this. Thank you.

[dense tapir]

well then use my code, i use it to attach scripts to spawned enemys

[hexed oak]

Was able to get my single sound effect randomizer working that changed the pitch/volume of the sound effect to make it seem like there were more than just 1 sfx. It created a new AudioSource for each sfx playing--which created a lot of garbage, so I implemented object pooling for it and now it seems to work well

[dense tapir]

anyone have idea for that?

[rigid island]

why are you spamming commands dawg

[surreal cloak]

if i have a game object name of a game object i have to destroy. How do i find that game object in the list by its name.

[rigid island]

GameObject.Find
totally not recommended doing this

[clever lagoon]

^he does not recommend it because it is generally considered best practice to keep REFERENCES to objects, rather than finding them by name, for performance reasons.

[rigid island]

not only perfomance but its also very very brittle

[ocean hollow]

I know that gamobj.find is slow but why? Is it really that expensive to go down the list of objs in the hierarchy until it finds the right one?

[rigid island]

strings , reflection, scanning all objects. All mix for a bad time 😉

[hexed oak]

but what if one frame loses a reference to my variable! It's sooo much better to run GameObject.Find("MyObject") in the Update() loop so that it will never lose the reference 😄

[ocean hollow]

the same reason you should never have tangled headphones

what if the sound gets lost along the way?

[hexed oak]

exactly, and since my pocket tangles my headphones anyways, I pre-tangle them before putting them in my pocket

[fleet matrix]

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

Even if the player is on top, he doesn't take it with him

[ocean hollow]

are you colliders set to is trigger?

[fleet matrix]

platform have 2d box collider is on Trigger

[ocean hollow]

how do you have it setup in your scene? is the player on the elevator instantly after play?

[fleet matrix]

wait

[ocean hollow]

so the problem is that the elevator isnt going up or the player isnt being parented?

[fleet matrix]

movement is lateral

[ocean hollow]

what about your debugs?

are they called?

[fleet matrix]

? i don't have error in the logs

[ocean hollow]

your debug.log statements in your funcs i mean

Debug.Log("Player Entered");

[fleet matrix]

doesn't write either

[ocean hollow]

then its a collider detection issue

[fleet matrix]

I have a collider box in trigger another one without trigger and a rigid body in kinematic are all 2d

[ocean hollow]

either your player doesnt have the player tag or you colliders are setup wrong

those are the only options

[fleet matrix]

player have tag Player for colliders i don't know

[upper pilot]

How would you generate a random int that is max inclusive without adding +1 to the max?
Say, I want random between 1 and 1 or random between 1 and 3.
First should return 1, second 1, 2 or 3.

Random Range is max exclusive for ints

[hard viper]

why would you not just add 1

it’s an int. this should not be complex

[upper pilot]

you are right I think 😄

just tired

[lean sail]

between 1 and 1
this case already exists, random.Next(1,1) will give you 1. But yea just add 1

[upper pilot]

I knew this had to be simple since google had nothing for inclusive int,int random lol

Following a tutorial on inventories, but I can't figure out how to make this accept the eventData from the OnDrag event using the new input system. Can anyone help with this?

I'm struggling to figure out what exact syntax it's wanting, for me to add the pointer info that it needs to function.

    public void OnDrag(GameObject obj, PointerEventData eventData)
    {
        if (mouseItem.obj != null)
        {
            mouseItem.obj.GetComponent<RectTransform>().position = eventData.position;
        }
    }

And here's the function that that line is associated with

if i add 1time XP and wait for the end of the slider value calculate, then it works fine...
but if i add in short time more then 1time XP then it dont works fine...

its up to you, but you could use a library like LeanTween for the level up animation...

the lvl up and normal animation is same, the only different is the amount...

and the animation isnt the problem...

just the calculate if i add in short time few times of XP

[runic nimbus]

So my gun has a bunch of colliders, and my magazine has a bunch too. When I insert, it makes the whole thing freak out cause 2 rigidbodies are in eachother. How fix?
I don't want to use layers
There are many colliders and I cant do physics.ignorecollisions on all of them
I just want to make 2 rigidbodies have all of their colliders ignore eachother for some time

[ocean hollow]

why do you have rigidbodies on each section? colliders should be enough

[runic nimbus]

The magazine and gun are two separate objects.

They are independent of eachother.

VR btw

[ocean hollow]

oh then your question would be better in #🥽┃virtual-reality

[runic nimbus]

I have never gotten an answer from there.

This isn't exclusive to VR so I think it's okay here

[hexed pecan]

Why cant you do IgnoreCollisions on them..? That would do exactly what you want

And why would a magazine have many many colliders

[runic nimbus]

Doing that method for every combination of colliders on each object? There's 3 on the mag and 12 on the gun

[hexed pecan]

Sure, or just the comliders that can overlap

[runic nimbus]

Is that really the best way?

Just feels weird

[hexed pecan]

Or just remove the magazine's rigidbody when you insert it

[runic nimbus]

The colliders would still mess with the gun, I think

[hexed pecan]

If you make it a child of the gun then it will be part of the gun's rigidbody

[runic nimbus]

Multiplayer game, can't use parenting

Well, if there's no other way, then I'll do the combination thing

[mighty tide]

they just do it using physics

[high summit]

Wait why can’t you use parenting in multiplayer

Seems like an important part of hierarchy to not have access too

[zenith valve]

Hi people 👋 is anyone experienced with unity version control. I’ve set up a project with my collaborator but whenever he downloads the project on his end the folder is empty,
could I have missed a step? Please advice if you know. Thanks

[spring creek]

I use git, but it is similar. Have you commited your changes and pushed them to the cloud?

[merry stream]

so i'm making an ability system similar to GAS in unreal and am having issues coming up with a way to deal with "reverting effects." So like a temporary slow, or something like that. Any suggestions?

[hexed pecan]

in unreal

[zenith valve]

I clicked on Check in changes. I assume this pushed it to the cloud. Is there another option ?

[merry stream]

... making it in unity, similar to GAS in unreal

[runic nimbus]

With a networking library that does rollback (going back in time to correct mistakes if the client disagrees with the server) like Fusion, doing parenting is very hard to manage with that.

Whereas with regular values like floats and vector3s, they can be simply saved and stored in a previous state

Not so much with one way actions like parenting

[high summit]

Suddenly multiplayer sounds much more daunting to set up

how do you handle simple things that normally use parenting such as moving platforms though

[runic nimbus]

Dude, it sucks. Multiplayer is the hardest thing you can do in game development.
But it's all worth it, nothing beats playing a game with your own players

[high summit]

The first game I’m trying to make is meant to be a multiplayer game so I’ve been trying to future proof all my code for when I implement it

[runic nimbus]

Stuff like moving platforms is handled manually, but in the case of Fusion they provide a very comprehensive (and surprisingly easy!) kinematic character controller all made to work with multiplayer and moving platforms.

[runic nimbus]

I tried the same thing with my first ever project, the first task was to learn Unity, and then convert it over to multiplayer.
Not gonna happen, lol. There are so many structural differences that in the end it's just easier to start over, bringing over only your assets and 25% of the code that could still be used in multiplayer.

So I would suggest dedicating this to learn as much as you can about Unity and C#, then starting fresh with some multiplayer samples to learn networking.

[high summit]

Luckily in my case I haven’t gone too deep yet so I only have a dungeon generator and a player controller that I was planning to change anyways

[runic nimbus]

To be clear, you can use parenting in multiplayer, but most modern networking libraries do this thing called prediction, you can see it in action in multiplayer cause your character moves before getting a ping back from the server. Your client is predicting that it can do this, so it does it locally first to give the user a very sharp response.

[late lion]

Make it so the change isn't destructive. Then you don't have to revert the effect, just remove it. As in, the effect is "applied" by evaluating each effect that is currently active at any given time.

[runic nimbus]

If for some reason, you actually couldn't move in that moment (like if you were already dead on the server) but you did anyway on your client, it will do a rollback. This means rubber banding you back to your old position.

What happens with parenting, is you need to specifically tell Fusion that if something goes wrong, you need to unparent it to roll back

I just found moving objects regularly to be less of a headache

[high summit]

So parenting is only an issue with things that are changing basically, but if it’s something like the generated dungeon with one time changes it wouldn’t matter?

[runic nimbus]

Oh well yeah, cause there's no case where that could go wrong. Everyone needs to generate that dungeon on their client.
It's only a problem if there's a chance that the situation is different on the server than on your client, so your client does something impossible and then needs to cancel it (rollback)

[rain minnow]

i just took a look. elapsedTime is used incorrectly for the lerp, and it seems your coroutines are overlapping each other, which is probably causing the experience issue . . .

[high summit]

Glad to know I don’t need to convert that in some way, it’s complicated enough already lmao

[merry stream]

i'm not sure exactly what you mean, do you mind taking a look at my code? https://gdl.space/ibiwexerek.cs

i have it somewhat working, but it feels hacky

[late lion]

What I mean is that you don't save any "current" modified value. If you want to know the current modified value, you take the base value and apply all the current modifiers on it. Then if you want to remove a modifier, you just remove it from the list. The next time you calculate the modified value, that modifier won't affect it.

[agile carbon]

What does that mean?

[vocal sorrel]

the friction from the physics system makes the wheels rotate by themselves

[agile carbon]

Yes but it won’t make the chassis rotate

Therefore I don’t know where the rear wheels go.

[vocal sorrel]

uhhh, can you explain a bit more?

[agile carbon]

When your car steers what happens

You turn left sure if ur steering left

[vocal sorrel]

oh i see

[agile carbon]

But your front tires move in the direction of the steering direction

But your chassis rotates

[vocal sorrel]

wheels rotate but the car itself does not

right?

[agile carbon]

But in real life it does

And I need to simulate it

[vocal sorrel]

ok,in that case you should just rotate the forward vector

[agile carbon]

Wdym

The car doesn’t rotate to the direction of the wheels

[vocal sorrel]

essentially this

an object rotating is basically this

two vectors

[agile carbon]

Yes

[vocal sorrel]

your forward vector

[agile carbon]

This is the car rotating around the ackermann point

[vocal sorrel]

and you add a sideways force to that forward vector

[vocal sorrel]

yup

[agile carbon]

But how would that actually make the car rotate

[vocal sorrel]

you are moving sideways as well as moving forward, thus causing the rotation

[agile carbon]

Ye but I can’t rotate the car just by adding force

[vocal sorrel]

or maybe you could just cheat your way out and rotate the car itself a small amount, causing the car to steer like it should

[agile carbon]

Then it’s not realistic

[vocal sorrel]

can you add angular foce?

[cosmic rain]

When a force is applied at different direction on 2 different points of an object(presumably on different ends from center of mass), it would rotate.

[vocal sorrel]

yes

[cosmic rain]

Think of a needle of a compas.

[agile carbon]

That’s a thing?

[vocal sorrel]

yes

[agile carbon]

But how would I do that to a gameobject

[vocal sorrel]

think of it as when you rotate a valve

[cosmic rain]

You can apply force to an rb at a certain position

[wide dock]

https://docs.unity3d.com/ScriptReference/Rigidbody.AddForceAtPosition.html

[vocal sorrel]

wait, that exists?

good to know

[agile carbon]

Oh fr. Holy shit I saw a YouTube video abt steering and that’s prolly how he did it

Then I won’t need to calculate rear position because it’s a child

🙏 PEAISE RHE FODS

[cosmic rain]

Sometimes good to check the API docs to see what methods and properties are available.

[vocal sorrel]

i see

[grand bobcat]

https://gdl.space/reqarehoxa.cs
For some reason whenever this code is run it crashes at a certain point that seems to be different every time. Im not sure why. A very similar but slightly diferent verison of the script worked just fine, and ive made sure it isnt any of the scripts that this references, so im not sure what the error could be

[cosmic rain]

Is it an actual crash or a freeze?

[grand bobcat]

"application is not responding" followed by it closing

so an actual crash

[cosmic rain]

This is probably a freeze.
That while loop in Spawn has a lot of potential for being an infinite loop.

[grand bobcat]

i thought that too but i cant see a reasaon for it to be if it is

[cosmic rain]

Since you're asking in code general channel, you should know how to use a debugger, so use it when the freeze occurs, to see what the code is doing.

[grand bobcat]

Got it 👍

will try

[lean sail]

i would add a max iteration counter to that while loop and attach the debugger with a breakpoint. if the if statement in that while loop is never true then tempVal never changes

[twilit scaffold]

I have found a C# course that is working for me. Perhaps it will help others too. I have to play at min 1.5 speed though
https://www.youtube.com/watch?v=DSbgl48VFLg&list=PLJitdQVsSaf7nHcznVnW7ALB2K514QKk_

[dense tapir]

what you mean with "i use elapsedTime incorrectly"?

and why should the coroutines overlapping each other? the first coroutine will stopped if not lvl up, and start the second if lvl up...

they never can overlap each other...(assuming I only start 1 process to add XP)...if i start a second then sure, but thats the question, that is what i ask here...

so now i need ask a second question...

thanks that you want to help me...but how you help me if you explain (just with other words) the problem what i explained before?

So I'll explain it again so that the last person understands what I'm explaining instead of trying to explain it again without helping me😪

If I only do 1 process to add XP then it works fine! without problems!
But if I start several processes to add to XP in a short time, and then

e.g. from process1 the XP should go from 30 to 50...
and at 40 another process is started, then not the 50 + new process, but 40 + new process is calculated... so always the value at which the currentValue is currently in the change process, instead of the value where the currentValue should go...

bet if change the object to a list with a wheel class it would do better

Oh have u made a car before

I’m not using wheelcolliders btw

[hidden compass]

I made mine with a big sphere collider.. like a hamster ball

[mighty tide]

well if your looking for it to be realistic like you said its better to uses them

[agile carbon]

It defeats the purpose of the project a bit tho

Also there is no steering in that script

[mighty tide]

yes there is

[hidden compass]

#archived-code-general message

From way up there

[spring creek]

Hmmm... so you don't have any rigidbodies or use physx? You're just doing math and setting the transform with manual spatial queries?
Tough. But kudos

[hidden compass]

Realism is wheel colliders or a form of them.. Arcade kinda just translates and the wheels are more just graphics

Wheels should be child of car anyway and should roll with the chassis

[agile carbon]

That’s the plan. Though I think maybe it’s a bit too extreme for a first attempt at cars though I won’t use wheel colliders.

I think I’ll use a rigidbody in the chassis

[hidden compass]

Make a hover car

Add wheels later

[agile carbon]

And apply forces at specific parts of the car causing rotation

[hidden compass]

That'll work

Axle points

[agile carbon]

Yes

And I’ll code the wheels myself

Including slip and stiff

And also calculating steering angle

Cause ima do ackermann steering and I will need to code differentials

[mighty tide]

have looked a unity's source code

[hidden compass]

lol, no wheel colliders

[mighty tide]

bouncy

[hidden compass]

just axle points and math

[agile carbon]

No, why?

[hidden compass]

never got it to drive good tho

too slippery w/o wheel colliders.. and i never wrote any friction forces

[agile carbon]

That’s no wheel colliders?

[hidden compass]

ya, its just applying upwards forces at each sphere u see

[agile carbon]

Oh u used unitys fric to on

Friction

I just used circumference of wheel to tackle distance

And will eventually apply slip

[hidden compass]

basically a hover car

[hidden compass]

ya this is the only part i skipped

if i go back and add some slip / grip to the points where the raycasts hit the ground (but apply it to the car) it'd feel alot better

[agile carbon]

Rn I’m doing this in unity and Roblox studio. Roblox to make money and unity to make something quality

Roblox makes it too easy dawg

[hidden compass]

good luck on the car..

[agile carbon]

Wheels work on the ground too easily

[agile carbon]

lol

[hidden compass]

car controller and character controllers always eat up so much time trying to get them to feel good

[agile carbon]

Appreciate it. If h wanna join on the project feel free to lmk

[agile carbon]

I agree.

[vocal sorrel]

it is absolutely worth it tho

a player may just quit playing just because controlling something just feels weird

[mighty tide]

have your tried a physics mat

[hidden compass]

not yet.. since the car floats there really wasnt a need yet

i just apply forces and torque to the floating collider

[agile carbon]

What’s that

[hidden compass]

physics material

[hidden compass]

absolutely, and not to mention the re-useability.. if u nail down a good controller u can package it up and re-use it as a base for every other project

[vocal sorrel]

yessss

[agile carbon]

That’s the problem with Roblox. Every Roblox car handles like shit

[agile carbon]

And I don’t know why

And I wanna make it better

[hidden compass]

been perfecting mine since 2020 ;D

[noble mica]

What do you guys think is better for shooting projectile bullets:

_rigidbody.velocity = transform.forward * speed;

_rigidbody.MovePosition(transform.position + Vector3.forward * (_projectileSpeed.Value * Time.fixedDeltaTime));

[hidden compass]

i use the first one.. can't say which ones better

[agile carbon]

Why is ur rigidbody hidden 💀

[hidden compass]

grabs it in Awake() i imagine

[noble mica]

yep

[hidden compass]

first method looks alot easier too..

[noble mica]

I was getting alot of of shooting in one position rather than using velocity

[mighty tide]

he uses getcomponet

[noble mica]

Yeah

private void Awake()
{
_rigidbody = GetComponent<Rigidbody>();
}

[hidden compass]

GetComponent<Rigidbody>().AddForce(transform.forward * force,ForceMode.Impulse);

[noble mica]

I was told Addforce might be a bad idea doing a top down shooter

[hidden compass]

maybe

[rain minnow]

Depends on the person and how they code their movement . . .

[mighty tide]

your right

[noble mica]

I just looked it up Velocity moves the object at a constant rate vs Addforce only pushes it which has a way of stopping at some point

[hidden compass]

if u dont use gravity i wouldnt see where addforce would be a problem

even on a top down shooter

[agile carbon]

U made that?

[hidden compass]

no gravity and no drag

he infinite bullet

[hidden compass]

ya

[agile carbon]

Beautiful ash

[spring creek]

Sounds like a fair compromise. Cool project. You'll definitely learn a lot

[hidden compass]

ty

[noble mica]

I see so using gravity would be better to use addforce to simulate gravity within bullets

[agile carbon]

I think so too. It’s just frustrating because you want to make it realistic but you want to make it possible

[noble mica]

What about moveposition

[hidden compass]

ive only ever used moveposition on a character type rigidbody

never on a bullet.. so idk

[noble mica]

Yeah I used it for moving too but it also ended up jittering

[hidden compass]

crank up thta interpolation 😅

[mighty tide]

working on a checkpoint system

[spring creek]

MovePosition on a bullet would require you doing all the physics yourself. It is meant mostly for kinematic rigidbodies

[hidden compass]

addforce with no drag/gravity, or velocity = i think are u two best bets

[noble mica]

Appreciate you so if I wanted to make more dynamic bullets down the line Im guessing Addforce is the best one

[hidden compass]

addforce would def be more realistic

would slow eventually and add bullet drop

[spring creek]

Yeah, just one call with ForceMode.Impulse is super easy

[mighty tide]

do yall this is a great implication

[hidden compass]

is that ?

[mighty tide]

no fleets

is free for preview

[noble mica]

Just so I make sure.
Velocity - for constant movement
Addforce - for more realistic bullet movement
MovePosition - For more character based movement

[agile carbon]

Namespaces r used a lot? I didn’t think so

[hidden compass]

AddForce has different ForceModes. so its a variety of things it can be

[spring creek]

I mean, no.
MovePosition is for kinematic bodies.
AddForce is for the physics engine to handle velocity and reactive forces for yoy
Velocity is to give you more control

[hidden compass]

i used Impulse in my example.. so its all the Force at once

[agile carbon]

Holy fuck @hidden compass I remember you

Holy ceap

[spring creek]

The last two are for dynamic bodies only, meaning you HAVE to do MovePosition or rb.position = for kinematic

[agile carbon]

Ur username just rung something in my head

[mighty tide]

namespace is mainly for the assemblys

[agile carbon]

Like a year or two ago you just started out

[hidden compass]

ya, its going on 3 years or so now

[agile carbon]

Lmao that’s funny

[hidden compass]

still hanging in there 😄

[agile carbon]

I’ve been running year-long breaks

[hidden compass]

as long as u dont forget too much between, lol

[noble mica]

Appreciate it guys

[agile carbon]

So like utils?

[agile carbon]

Forgot it all

[mighty tide]

it make sure i don't compile unnecessary things after changing something in the code

[hidden compass]

namespaces are like collections/groupings of code that are related

[mighty tide]

helps speed up compile times

[agile carbon]

Ah ok

[hidden compass]

Utils is a decent example

[agile carbon]

Smells like a library

[mighty tide]

yup

i have 4

keeps things clean

[hidden compass]

i have a few

mine arent in folders tho 😬

they're just scattered everyhwere

[mighty tide]

it also cleans up my solutions

i would marry assemblys

[quartz folio]

namespaces and assemblies are unrelated

[hidden compass]

ya, my ide doesnt even sort with namespaces (i havent figured out how to yet)

[quartz folio]

Namespaces are just handy organisational groups that make it clear how things are differentiated

[hidden compass]

assembs, yea

[quartz folio]

Assemblies are functionally separated groups of code that can compile differently for different platforms and define relationships with other assemblies

[mighty tide]

no they are

namespace is the grouping

[quartz folio]

Nope. What you're seeing are assemblies.

Namespaces are like last names, if you have two dudes named Tom then you can tell them apart by their last name.
Assemblies are like families, you can have hierarchical relationships between different families, but it has no real bearing on somebody's name, and the only connection between that and namespaces is that it's convention for people in the same family to have related last names.

[vocal sorrel]

it feels like i am a kid learning again

does unity have any built-in timers? or do i have to just substract delta time over a float?

[vocal sorrel]

don't mind if i save this

[mighty tide]

Mainly I use namespace so fleet is happy

[hidden compass]

had to look up Fleet

looks like JetBrains version of VSCode

[spring creek]

There are coroutines

And async

[vocal sorrel]

how much control do i have over those?

like, for example

[spring creek]

Well... complete control of course

[quartz folio]

It kinda is, but it's got more of a focus on cloud integration. Sadly when I tried it about it year ago it was really bad, but it's probably improved since then
Part of why I like Rider is that it just works, and it works well—which Fleet absolutely did not

[vocal sorrel]

if i wanted to add time stop, would i be able to completely pause the coroutine?

[spring creek]

You would have to cache values, and stop the coroutine afaik

You would then restart ut where it was

Or you could possibly have a bool to prevent it from "running" while it loops doing nothing

Like an early return, but just yielding

[vocal sorrel]

i see

guess i have to try

[hidden compass]

funny little promotion image.. could u imagine? "hey bro get off my line!"

[lean sail]

i was looking at implementing IDisposable on my Items (poco), so they can destroy an instantiated SO when needed. This SO is instantiated in the ctor, initially I destroyed in the dtor but apparently the dtor isn't always called.
From what i see online, it looks like im required to call Dispose myself. Is there some way to have it automatically called when its not referenced by anything? Right now im concerened about in the future, if one class ends up doing

public void MemoryLeakSimulator() 
{
  new Item();
}

Ill have an instantiated SO just sitting around with no way to destroy it myself

I was planning on using a poco instead of the SO, but im still curious if such thing above is possible to solve.

[quartz folio]

Is there some way to have it automatically called when its not referenced by anything?
No. Only the dtor, which you generally shouldn't use

[lean sail]

I guess my solution is either guarantee i dispose everywhere, or not use SO here still then. Thanks

[craggy veldt]

if it was just a plain c# (non-unityobject) we can do this GC.Collect() and then check WeakReference.IsAlive then again who's in their correct minds would do that 😂

[lean sail]

this stuff is a bit above me, so just asking even though i likely wont use it. Would this even be possible to enforce with the case above of some class just calling new Item() only? my Item class is a poco, but it holds an instantied SO

[craggy veldt]

I'm not sure the side effects are due to you have a reference to unityobjects in there

also it's not worth tho, gc.collect is slow af

[quartz folio]

Sadly you should just call Dispose, that's how it's intended to work

Just as you should call Destroy on any UnityEngine.Object types you allocate (even those allocated by material calls)

[craggy veldt]

yeah, even if it's just a plain c# class, weakreffing has a limitation once it's successfully being weakrefd, you can't keep it for a long period of times due to it might be promoted to gen2.. also not sure if gen2 stuff exists in il2cpp

[lean sail]

Yea ill just rework this so i dont instantiate an SO. Then Item gets destroyed, and the poco inside will also be destroyed i believe.
I've never really looked too deep into gc or memory stuff works so this has been pretty eye opening

[quartz folio]

No managed memory is released until all references are null

and UnityEngine.Objects aren't released unless Destroy is called, or a complete scene reload occurs, or Resources.UnloadUnusedAssets (which is very expensive)

to be clear, UnityEngine.Objects have native and managed parts, and so Destroy doesn't release the managed part

For example, with a reference to an SO that has a reference to a managed object, calling Destroy releases the native memory and the SO will evaluate to null, but the managed SO and its references are still in memory until you also set the reference to the SO to null

[vocal sorrel]

how do i change a single color from a color block?

do i need to make a new color block and the nreplace the original one?

[latent latch]

ye

[vocal sorrel]

oh

ok, thanks :)

[spring creek]

What is a color block? Haven't heard that term

[vocal sorrel]

this thing

[hidden compass]

has to do with buttons

[vocal sorrel]

selectables seem to have it according to unity docs

[rigid island]

you replace whole thing iirc

[spring creek]

Gotcha gotcha. Thanks

[vocal sorrel]

yup, did that and it worked correctly

[lean sail]

i think i understand, thanks for the explanation

[burnt crypt]

Any linux devs here?

[dusk apex]

You're probably better off just asking your question https://dontasktoask.com/
This is the code related general channel.

[burnt crypt]

No I'm just here to flex

I just wrote a pointer scanner for linux

[rigid island]

not impressed

[burnt crypt]

Literally the very first one on linux

Which makes reverse engineering (and cheating) on linux games substantially easier

[craggy veldt]

what you're flexin about, me don't understand

[warm wren]

literally not related to unity

[burnt crypt]

Linux anticheat is ass, which is usually balanced out by linux game-reversing tooling also being ass

I just made the tooling way better

[burnt crypt]

Your engine uses pointers bozo

[craggy veldt]

all games made with Unity are easy to reverse enginered already

[burnt crypt]

Thats true

Its still cool asf

[craggy veldt]

😅 I don't understand this

[leaden ice]

Congratulations here's your duck 🦆

[burnt crypt]

Ty hehe

[compact spire]

I'm not finding much on dependency injection and it's practical use cases in Unity, is it just not used very much?

Trying to sort out how it fits in with delegates/scriptableobjects/monobehaviors

[latent latch]

I once used ghidra so technically im pretty much hackerman too

[burnt crypt]

You should put your game in DNSpy

Was really funny seeing the gamedev course guys at my uni do this to their unity games

[craggy veldt]

aight, now it's time to learn c#, here https://learn.microsoft.com/en-us/dotnet/api/system.type?view=net-8.0

you can brag about it once you're done

[burnt crypt]

Ew microsoft

I'll be honest you guys are safe because I don't want to touch c# with a 10 foot pole

Stack machines can btfo

[craggy veldt]

aight you're just trolling in here

[hidden compass]

ya, it seems There's very few options for using Dependency Injection in Unity. just reading thru the forums.. quite a few posts discussing it..

[burnt crypt]

C# being a stack machine us a legitimate complaikt

Complaint

[hidden compass]

https://www.what-could-possibly-go-wrong.com/dependency-injection-for-unity-part-1/?utm_source=ash&utm_medium=ash-reddit-unity3d&utm_campaign=dependency-injection3 @compact spire

[latent latch]

Dependency Injection though is pretty much the concept of object pooling

[burnt crypt]

And I don't mean that it uses stacks for control flow, I mean that the c# virtual machine literally doesn't have more than like 3 general purpose registers

Which is aids

[compact spire]

wait, what does object pooling have to do with dependency injection?

[hidden compass]

heres what that article covers.. its the most decent one ive seen so far

altho i dont know nothing about it tbh, just searching for ya

[compact spire]

@hidden compass Yeah that might have some of the information I'm looking for, I wasn't having the best luck on youtube.

[hidden compass]

found it in a reddit post (screenshot from part2) of that article

[latent latch]

Say you want to spawn an enemy with gun and bullets:
step 1: Dequeue EnemyMono
step 2: Dequeue GunMono
step 3: Dequeue BulletMono

attach em together, and bam dependency injection

technically all monos could be considered dependent on injection cause you don't have access to a normal constructor

[compact spire]

Yeah that was one of the things I was trying to figure out, since they seem to overlap a bit.

[burnt crypt]

Do you guys ever use non-OOP programming paradigms or is it infeasible for gamedev?

[compact spire]

what like functional programming?

[latent latch]

oop is pretty bad alone

[burnt crypt]

Yeah

[latent latch]

you need ECS or compositional approach to really have a manageable workflow

[compact spire]

I mean you could, but from what I understand is that disregarding OOP for 100% functional programming seems like a bad idea.

[burnt crypt]

Ngl, the fact that you guys have to consider design patterns this seriously is really cool

[compact spire]

https://www.youtube.com/watch?v=nuML9SmdbJ4

[burnt crypt]

How is this different from OOP?

[hidden compass]

much

[spring creek]

Of course?

[hidden compass]

ECS is over my head

[latent latch]

OOP you can dig a hole pretty easily if derive your behaviours too deep, or spread too thin

[burnt crypt]

Functional is a delusion anyway, its always imperative when serious work has to get done

[compact spire]

ECS is black magic I don't have the inclination to understand

It's hard enough I keep replacing everything I'm doing over an dover.

I got halfway through converting to use a service locator, now I'm on to DI

[spring creek]

Entities are an id
Components hold data
Systems iterate archetypes
Archetypes are entities with specific components, which exist in the same contiguous chunk of memory
Data Locality means an huge boost to performance when done right

[burnt crypt]

I mean functional does not glue at all with the model of computation all machines are based on. Functional requires an imperative abstraction layer

[latent latch]

With OOP you can fall into problems such that you have like an enemy
Orc -> RangeOrc
-> MeleeOrc
-> MagicOrc

But now the question is what if you want your orc to melee and be range? Do you make a MeleeMagicOrc? And this is the problem with OOP alone.

[compact spire]

@spring creek Conceptually I kind of get it, and I've looked at some demo's of how it's setup, but writing something around it is a whole other pickle

[spring creek]

I found it rather pleasant. I moved to Bevy almost entirely to chase a more ECS focused engine

Just takes a different way of considering it

[hidden compass]

i just re-iterate and try to plan out my projects so i dont have to worry about that Orc issue

[burnt crypt]

Multiple inheritance?

[latent latch]

Right, c# you have interfaces instead of that, but even then you can run into the diamond problem of multiple inheritance

[compact spire]

It's too different than what I'm used to, Unity is hard enough when coming from something like a simple backend service.

[cosmic rain]

Gamedev is hard.

[hidden compass]

if Unity's editor wasn't what it was I wouldn't have learned to code

[burnt crypt]

Actually is

Guys that make game engines are just as insane if not more insane than OS devs

[high summit]

Is FishNet the general consensus for setting up multiplayer?

[cosmic rain]

No

[burnt crypt]

FishNet?

[compact spire]

FishNet? is that new?

[hidden compass]

ive heard about that here recently.. didnt know what it was

[burnt crypt]

Where did you learn stuff like this

[cosmic rain]

There is no general consensus. Use whatever fits your project

[high summit]

Doing a little research right now and seems like Mirror was the previous one typically used

[burnt crypt]

Is it the 'correct way' to use c#?

[high summit]

seems like FishNet is new

[hidden compass]

Mirror is easy to set up.. Lobby's Connections and stuff

[latent latch]

Trial and error of making a lot of bad hierarchies and rebuilding them

[burnt crypt]

Why did you stick with unity?

[latent latch]

because Unreal forces blueprints and that's a job of its own

[hidden compass]

unity is a prototyping beast

[burnt crypt]

Unrelated to the thing I replied to but still hoho ^-^

[high summit]

If I were to be more specific, I want to make something with small lobbies (2-4, maybe up to 8) hosted by one of the players. Not sure which would work best though since I’ve never set up multiplayer before

[burnt crypt]

Must be insane to work at both such high and low abstraction

[cosmic rain]

Research all the available frameworks and their features.
But generally, they all do the same thing under the hood, so it's a lot about personal preference.

[compact spire]

I think Photon is one of the more popular options for Untiy

for multiplayer

[burnt crypt]

I had to use java for the first time in yearssss recently and it kind of hit me how namespaces are just a default that you don't question

Or these fancy ass build systems

[hidden compass]

all of those mentioned that ive seen use their own servers to host games.. not sure about having one of hte players be host..

not sure what solution fits there

[compact spire]

so you are looking for something that supports peer 2 peer?

[latent latch]

Fishnet is aight, but their documentation is a little arse. I do think Unity's networking library is probably one of their best modules and a great starting point despite behind on some features.

[burnt crypt]

Fellow 3:44AM-er

Do you guys write your own protocols for online play

[cosmic rain]

All of the mentioned support p2p. In fact that's probably the most common use case.

[burnt crypt]

Or use libraries that come with a framework that you just fill out

[hidden compass]

oh.. i didn't know that.. i thought they all used their own servers so they could cap player count.. and provide subscription services

[cosmic rain]

They might be using lobby servers for establishing the p2p connection though

[hidden compass]

ahh perhaps..

[cosmic rain]

That's what the lobby servers are about.

[latent latch]

https://docs-multiplayer.unity3d.com/netcode/current/about/
Worth starting with since a lot of these libraries following similar concepts, and it's also 'free'

[hidden compass]

TIL

[cosmic rain]

Because it's generally impossible to host a server normally via home internet.

[burnt crypt]

router will kill all incoming conn requests

[compact spire]

Wouldn't be using P2P only be difficult due to network shenanigans like NATs, or is that not really an issue to think about?

[burnt crypt]

You need servers to listen for connections, a typical home router doesn't let any connection request into a home network

[compact spire]

I see

[cosmic rain]

It is the issue. But the only way to solve it is to have a publicly available server that can connect the 2 clients. It's only needed initially to establish the connection between the two.

Though, I guess that depends on the framework

With photon I think all the traffic goes through such a server

[burnt crypt]

Mom can I port forward pleaseee

Pleaseeee

👉 👈

[hidden compass]

wow, theres alot of documentation now for Netcode for GO

[latent latch]

best documentation unity has put out

because there's actual tech docs that explain to you the process of it all

[hidden compass]

i might give this a try.. just to add a MP prototype to my list.. its been a while.. since I made a photon lobby / MP walking sim

[latent latch]

https://docs-multiplayer.unity3d.com/netcode/current/learn/dealing-with-latency/

so much effort placed into this it's unreal (I made pun teehee)

[hidden compass]

lol.. 😄

ya, all their docs need to look like this

pinned on Github now i just need a mp game idea 😅

[dark kindle]

speaking of docs, i want to know how everyone documents their code for their games? what tool is best to use? a wiki?

[compact spire]

documents their code?

[dark kindle]

yes, like if i work on another project i want to come back and still remember how thing work

[compact spire]

write readable code, or if that fails, write comments

[dark kindle]

yes, but maybe show screenshots of gameplay and what objects in screen is associate with code.. i cant embed screenshots in code, can i? unless i can embed links in c# or if i hover over a certain code a screenshot appear

[compact spire]

That is a bit far

[dark kindle]

thank for input though

[compact spire]

Generally if you take the time you name your variables/classes/methods ect in a way that will make sense to future you

[lean sail]

are you working with a team? in small teams (or especially alone) i wouldnt waste time on this

[compact spire]

and you don't make a bunch of monolithic hunks of code, it should be readable.

[west sparrow]

For some projects, if there is an API, I'll use doxygen and uml. But that's pretty rare.

I usually have a Readme in the project for the team, so when they grab a template from our repo, there is help getting going.

For bigger projects we do use an internal wiki. But I've been pushing the team to keep it to the readmes so they are versioned.

[dark kindle]

no, i work by myself for now. if i do open source project then that could be different case. which i want to in future. Otherwise contributor might scratch head what i trying to do

[west sparrow]

In my case, I have some very thorough all in one templates (especially in VR). So having a gentle reminder of how to setup something is always a plus.

[dark kindle]

thank, that soudn good

[west sparrow]

It's also helpful to document how to deal with odd VR frameworks that need special toggles and such. But wiki & readmes.

At the top of your code it's helpful to use /// three slashes for proper documentation. Then if you do need to, you can use doxygen later to generate code docs. And keeping it in its own namespace is always a good idea too.

[dark kindle]

it a game engine so maybe i also need to understand myself the configuration, for example game objects, references, ui layout etc., which i may need more than what comment provide

sound good

[soft shard]

I find establishing some architecture in your code can help with readability later, since if you understand how a certain pattern works, and your code more-or-less follows that pattern, it should be easy enough to follow along your logic later, if you plan on templating your code or turning it into a framework or something open source, then adding summary comments can help for public functions and properties, the downside with comments or wikis, is that they also need to be maintained when code changes or gets refactored, or if you make certain functions, events, etc obsolete, and while working on a project, code changes often from my experience so it can kind of be an additional thing to manage imo alongside source control

[latent latch]

You'd probably want to minimize where the problem is and if it's more network related, take it over to #archived-networking or the photon server

[lean sail]

you really wont get better multiplayer help here. a lot of people here dont even touch multiplayer and wouldnt be able to help you with photon specific stuff

[hidden compass]

I use http://www.notion.io it's easy to post screenshots/video clips and codeblocks.. I also have a index of systems and todo lists

Github is another good place to document ur code.. if you learn markdown you can make some good Readme files with images and all that

[spring creek]

I've been using it for school notes and it's been really nice. Being able to do inline LaTeX is super helpful.
Can get really complex with it if you want
I've only barely scratched the surface

[hidden compass]

Oh abs.. I had to put it aside. I was starting to color code everything.. had an index list of emoji as symbols n all

[merry stream]

how do I conditionally show fields in the inspector, for example only reveal certain ones if a certain enum is set to something

I figure its possible with an editor script

[knotty sun]

yes, write a custom inspector or use something like Odin Inspector

[latent latch]

https://dbrizov.github.io/na-docs/attributes/meta_attributes/show_hide_if.html

So I've this dilemma on when to remove an object that's contained and managed by another class. When I access this object, should I allow to return the reference and keep the reference contained in the manager? Or should I always remove the reference from the container when it is to be accessed?

For example, should I have a method of:

public bool TryGetAndRemoveObjectAtIndex(int index, out Object obj)```
Otherwise, who should be in charge of removing these references from the container if the object is consumed?

[chilly surge]

Pretty much dependent on your usage pattern.

And I mean, you can always have both, like Queue<T> has both Peek and Dequeue.

[latent latch]

For instance, an inventory with a health potion. You can access the inventory and grab the reference and drink it -> the object is consumed and destroyed.
Two ways I can see handling this, one being to just remove the health potion as I access it and let the health potion destroy itself, or reinsert it later if it's not to be consumed (and only modified)

The other way is the health potion needs to do a callback to the inventory and tell it that it's to be destroyed and remove that reference.

Or maybe even let the handler manage the usage of the potion instead?

I think the biggest issue is keeping track of references that would be modified, but still be active in the inventory.

Perhaps the modification consumes it in the proccess, now I would need to remove it from the inventory x_x

Maybe the idea is to just keep all behaviors on the items themselves private and bound by a delegate and let the manager call the Use() methods and such

[merry stream]

thanks works amazing

[placid summit]

how do you manage comments on both interfaces and implementations when you just want them to sync?!

[latent latch]

Usually if you stick a comment above methods you do get some of that information when you hover over the methods elsewhere, but im not too sure if that works with interfaces

[trim schooner]

It's not just a comment above a method which will give you info.. it's a particular type of comment. Do three /'s above it and it'll give you the summary comment, which allows you to add the params/ etc

Do you have to create all scripts in Unity or only monobehaviors?

So Unity creates meta files

Which afaik are needed for things like showing script in the inspector

[trim schooner]

The meta file has nothing to do with where you create the script, they automatically get created for everything that gets put into the project.
Don't even need to make a monobehaviour in Unity.

[upper pilot]

They are not created when I make a c# file in VS, someone told me before to always make them through Unity

We had this issue before

Is that not the case?

[trim schooner]

I've never not created them in unity, because.. why wouldn't you 😄

But I don't see why it would make a difference.. Unity auto creates a meta file for everything in the assets folder

Just tested it, created a new class in VS.. saved as into my Unity projects scrips folder.. meta file is created, as expected.

[tardy crypt]

Me every time I add a feature in my game: "whew, got it working, let's go on to the next thing." Me when I need to change that feature: "wtf was I doing, I have to rewrite this whole thing."

[heady iris]

The only difference is that Unity has to see the file before it'll create a .meta file (and before it'll update the .csproj files to include the new file)

So if you create a script outside of Unity and don't let Unity reload (I have auto-reload disabled, for example), then there will be no .meta file yet, since Unity won't have imported the asset

[unreal temple]

I make all my scripts from vscode so I can use templates.

I have a plugin that creates the meta file for me too.

But it's not necessary. Only thing that matters is the csproj being updated (which the c# plugin does).

[upper pilot]

Because Unity auto compiles after each file is created so its a pain when I can do most of it in VS

[upper pilot]

Ah thats it, it didnt appear in VS if you didnt create it in Unity then.

I have auto reload I think, but I had an issue when creating file outside of Unity

People even recommended creating them via Unity here

[tardy crypt]

Looking for some guidance on a problem I'm trying to solve. I have some Monobehavior that needs to be dynamically given "effects" at runtime. The effects change the behavior of either the monobehavior or something that interacts with it. The main way I have been doing this was to just use polymorphism for the effects. In other words, base class "Effect," so the monobehavior stores a list of those effects and then I can add whatever sub classes I want during run time. The effects themselves define behavior of the effect in code. This seems to lead to a large class hierarchy which I kind of want to avoid due to how brittle it is. Is there a better way to implement something like this? TLDR: I want to dynamically give different behaviors to a monobehavior at runtime and I'm wondering if there are simple options other than polymorphism. Should I just make the effects a data store and implement the behaviors as a set of switch statements (say) in whatever components actually use the behavior?

[latent latch]

Composition

[heady iris]

this sounds reasonable; perhaps you've just been combining things that shouldn't be combined?

can you give an example of part of the hierarchy you don't like?

[tardy crypt]

ok let me see how to express this succinctly. this is a tile-based game. i have... things that can occupy tiles... let's call them terrain. the terrain imparts effects to the game. the effects that the terrain can have depend on the rest of the environment. so the idea was to have an "effects" class for the terrain and add/remove these effects from the terrain Monobehavior as the environment changes.

one example effect is modifying movement of the players' units. another is damaging them. another affects how the player's units can, themselves, affect the terrain.

the goal is to have a lot of different effects. i haven't really built these all out yet but i can see issues with overlapping functionality and whatnot. so i guess my question is, is this just a difficult problem that can be solved reasonably with polymorphism or is there an approach that is more amenable to the situation...

[heady iris]

The premise sounds fine to me.

[tardy crypt]

ok thanks for your input.

[heady iris]

One way I've handled this before was to give the effect class a bunch of virtual methods that all do nothing

so there's one for OnUnitEnter that you call whenever a unit enters the terrain tile

and the abstract base class's method is empty

another might be ModifyMovementCost(int currentCost)

the base class's method would just return currentCost

[latent latch]

Technically you are doing some polymorphic calls since I assume these effects take in a player ref

[heady iris]

you iterate over all of your effects and run the relevant method

most of them will do nothing; a few might actually have an effect

The other way would be to add interfaces for each kind of effect

not literally every concrete effect

but the more abstract ideas like "an effect that can apply to a unit"

[tardy crypt]

so i guess... the idea is that the abstract base class defines the list of possible things that can happen, and the child class determines whether the effects actually happen and what they do

[heady iris]

or maybe "an effect that applies to a unit when you enter the tile"

[hard viper]

I have a very tile-based game. I use ClassTypeReferences to tie the definition of a specific class to an SO. Each tile’s TileBase is tied to an SO with that classtypereference. Different things in code can instance the relevant class to use the code on command.

[heady iris]

Then you'd be filtering your big list of effects by type

[latent latch]

Yeah, my abilities class has like 5 lists and it checks if they are empty or not, but each list can contain similar behaviours.

[heady iris]

foreach (var effect in effects) {
  if (effect is IOnUnitEnterTile enterTileEffect) {
    enterTileEffect.Apply(unit);
  }
}

[hard viper]

My tile SO can also have a prefab tied to it if I need something more involved

[heady iris]

This one wouldn't be specific enough by itself.

since there are multiple situations where you apply an effect to a unit

[hard viper]

if I use ClassTypeReferences, I make sure to restrict it to classes that implement a specific interface or abstract base class

[heady iris]

One solution would be to store a separate list of effects for each situation where you use effects

[hard viper]

like my SOs have a few class type reference fields for: ICustomDraw, ConductivityStrategy, and TileMonobehaviour

[heady iris]

List<IUnitEffect> onEnterTile;
List<IUnitEffect> onExitTile;

e.g.

This is less convenient than just having a single list of all effects that currently apply to the tile.

[latent latch]

Targeting parameters seem pretty common to split with behaviors

[hard viper]

in this case, you can have a ClassTypeReference to a type that is constrained to either implement ITileEffect interface or extend TileEffect abstract base class.

[heady iris]

yeah, since "damage unit", "heal unit", and "give unit a bonus" are all things that need a Unit

[heady iris]

so an interface makes sense there

all of these kinds of effects share a requirement to be given a unit

[hard viper]

I would make an abstract base class for any sort of effect, and make many interfaces for different types of triggers

like ITileEffOnEnter, ITileEffOnLeave, ITileEffBombable, ITileEffBurnable, ITileEffConductive….

or whatever

[latent latch]

That's kinda what Ive came to the conclusion of when brainstorming these roguelite games

[hard viper]

then you have a reference to the one type for the type in an SO, and check if the type implenents a given interface

[tardy crypt]

ok so i guess what i'm hearing is... it's ok to have one or more collections of effects that specify functionality in code (whether by being child classes or by being interfaces), and just have clearly defined categories of uses for the effects so you can call them as appropriate in your monobehavior.

[hard viper]

if a tile effect needs any sort of connection between the different behaviours, then it should be one class for a tile with multiple interfaces, so they can cross talk.

[latent latch]

TriggerOverTime, TriggerOnHit, TriggerWhenHit

[hard viper]

if the behaviour is super separate (like in my case, ingame behaviour separate from level editor behaviour), then they should be split

[hard viper]

but generally yes

i strongly recommend using ClassTypeReferences plugin for this, and also making a giant dictionary that links every tile to an SO with actual info

Dictionary<TileBase, MySo> is basically mandatory

then you can do whatever the fuck you want in the SO to connect game logic

[tardy crypt]

i'm not sure what you mean by that. can you explain further?

[hard viper]

set booleans, enums, class references, etc

[hard viper]

Tilemap lets you use GetTile to query what tile is at a given coordinate

[heady iris]

I do something similar, except that it's Resources-based.

[hard viper]

when you know you interact with a tile a given coordinate, GetTile gives you a TileBase, which you now need to go get the actual game logic for

[heady iris]

In my case, I have a bunch of classes that derive from Module that add features to my Entities

For each class, I create a scriptable object asset (ModuleInfo) that lives in a Resources folder

It contains things like localized string references

[hard viper]

you want a giant Dictionary so you can go from TileBase to a permanent asset on disk that tells you wtf the tile does. In this case, a scriptable object

[tardy crypt]

why not just store the SO as a reference in the tile?

[heady iris]

I use the dictionary approach elsewhere, like to look up SO assets by a GUID I've attached to them

[heady iris]

you're associating something with each kind of tile

or module, or whatever

[hard viper]

SO has a reference to the tile in it. But If I call Tilemap.GetTile, how do I get the SO?

need a dictionary

[heady iris]

in my case, I could add an instance field to Module that holds a ModuleInfo reference

but then I'd have to manually assign that for every instance

The association isn't per-instance. It's per-type

So it doesn't make sense to use an instance field.

[tardy crypt]

hmm... in my case, the tile types are constructed dynamically based on environment.

[hard viper]

yeah, you want to have a separate connection of instance-data, and one big dictionary that makes it easy to query just the base data

[tardy crypt]

the set of effects are combinations of things based on the environment

[hard viper]

i gtg, but fen has u covered

[tardy crypt]

thanks

[heady iris]

Although, it sounds like Loup was describing per-instance information there.

i.e. associating a scriptable object asset with each individual tile

[heady iris]

and in this situation, I don't think you'd be referencing assets at all

[latent latch]

dictionary sounds fine

[heady iris]

each tile should just have a list of effects on it, and each effect should have its own configuration in it

[tardy crypt]

this sounds the most straightforward to me tbh...

[heady iris]

a DamageUnitsWhoEnterThisTile effect contains the amount of damage to do; it can stand on its own

[tardy crypt]

i kind of already have the infrastructure for this so... i think i'm going to just do this

[heady iris]

You just need to decide between:

• Every Effect has a crapload of do-nothing methods on it and overrides just a couple of them
• Effects implement various interfaces, and you filter your effects based on those interfaces

for the latter, you could do something a little interesting

public class HurtUnitsWhoEnterMe : Effect, IUnitEffect, IOnEnterTileEffect

IOnEnterTileEffect could be a completely empty interface

foreach (var effect in effects) {
  if (effect is IOnEnterTileEffect && effect is IUnitEffect unitEffect) {
    unitEffect.ApplyToUnit(unit);
  }
}

IOnEnterTileEffect doesn't actually specify any behavior at all. It's just a label.

[tardy crypt]

hmm... interesting

[heady iris]

IUnitEffect does specify behavior

[tardy crypt]

i like this idea, i might try it out

this might clean things up for me a bit

[heady iris]

I always feel weird when I'm manually filtering types like this

Instead of these "tag" interfaces, you could just have a way to ask an effect if it applies in a certain situation

where "situation" is an enum or something

[delicate flax]

sorry to those of you already in the know. but I just realized you can inline assignment in c#. 😅
so you can write this, as opposed to that. works for function calls to.
it's only a syntax thing, but figured I'd share for those of you that are like me and prefer to get rid of that extra line of code 😄

[tardy crypt]

right... that makes sense as well...

[latent latch]

I'm more of a stick to a single class and declare everything but check at runtime via enum (or instantiate the lists of behaviors and who cares if they are populated or not)

[heady iris]

oh yeah, = returns the assigned value or reference

which usually just causes confusion when people use it instead of ==

compiler warning for every time you discard the value returned by =

⚠️ 9999

[tardy crypt]

anyway thanks a lot for your help guys this stuff is currently implemented in a very ad hoc manner which has hampered my ability to extend it, you've given me some great ideas for how to systematize "effects"

every time i arrive at a new problem to solve or feature to implement, i think implementing that will be relatively easy but... then i sit down and think about it and it really requires a lot of time

[heady iris]

an effect system is like

two steps away from a programming language

The closer you get to implementing an entire programming language, the harder it becomes

[tardy crypt]

funny

[heady iris]

At some point you just cut your losses and implement some things in C#.

[tardy crypt]

Your "Effect" class just has a text field and a runtime compiler. No interfaces, no hierarchy. Just create new SOs for each effect and give it a name and a string parameter, into which you type your effect code.

I actually briefly considered doing that until I realized that debugging this would probably majorly suck.

Though I feel like large devs actually do this with scripting (e.g., LUA) and whatnot.

[latent latch]

Dota does a lor of lua

For its ability systems

I considered it

[tardy crypt]

I mean it's a nice way to decouple gameplay design logic from core gameplay logic.

but the infrastructure required for a small project is too high of a cost.

basically, even with the extremely frictionless nature of the C#/VS environment, this project still takes tons of time, so downgrading to whatever would be required for scripting would result in a significant slowdown.

[surreal cloak]

anyone have any idea of what is the best way to pull off something like this when the camera is looking at the body/gun. I was thinking of having a square collider coming out of the head that shows where the player is looking at and checking if its looking at a gun collier. 10 mins into itegrating it i realised how uterly retar*** my method was and i currently dont have any other ideas

and follow up question. Is it possible to have two "OnTriggerStay" methods for two colliders in the same class

[spring creek]

No

One method with the same name and signature per class

You can validate the collider type INSIDE the same OnTriggerStay, and simply do different things depending on the collider

[heady iris]

OnTrigger* methods don't tell you which of your colliders caused the message to be sent.

If you want multiple distinct colliders, you need to put them on different objects

[spring creek]

You can check the SHAPE if they are different.

Or check some parameter of the collider (like if one has a high radius and the other is small)
It is unweildy though

I agree that separate objects is generally the best way to go though
That's what I do

[tropic cave]

hello, any suggestion for a lite version of unity ? I dont want to really make a full game but to test some code on an objects with physics properties and such stuff

[spring creek]

I guess 2019 version is a bit smaller...

Other than that, not really

[tropic cave]

alright thank u

[hidden compass]

https://docs.unity3d.com/Packages/com.unity.tiny.all@0.32/manual/index.html

interesting

[sleek heath]

Godot but Unity be like:

[pale marsh]

Are these errors really that important, because the code works fine?

[heady iris]

This is a problem with the inspector.

I'll sometimes see then when I undo or destroy things.

[pale marsh]

is there a way to bypass it?

[heady iris]

it's usually solved by restarting the editor

assuming it's spamming the error constantly

[pale marsh]

yup

[pale marsh]

good to know that

[naive swallow]

In general, if you look at the stack trace and see no actual line numbers, it's the editor being fucky and a quick restart will at least supress it for a while

[pale marsh]

yeah I just restarted it and now its not showing anymore, so that will do it for now

thanks yall

[brittle haven]

How can I get the sizes of a sprite in a script?

[ocean hollow]

Like the dimensions of the texture itself?

[brittle haven]

yes

[swift falcon]

can someone please help me i want to make an object appear in unity in a 2d game when i hold down s and when i release it it disappears again

thats my script (it does not work)

using UnityEngine;

public class ShowOnKeyPress : MonoBehaviour
{

public GameObject objectToShow;


void Update()
{

    if (Input.GetKey(KeyCode.S))
    {

        if (objectToShow != null && !objectToShow.activeSelf)
            objectToShow.SetActive(true);
    }
    else
    {

        if (objectToShow != null && objectToShow.activeSelf)
            objectToShow.SetActive(false);
    }
}

}

[brittle haven]

size (width and height) (vector2)

[modern creek]

If this is the only thing controlling whether or not the object is active, just check if the object isn't null in Awake() instead of in Update(). ie - your code could be a lot simpler if it looked like:

public class ShowOnKeyPress : MonoBehaviour
{
  public GameObject objectToShow;
  private void Awake()
  {
    if (objectToShow == null)
    {
      // log a warning here or whatever
    }
  }
  private void Update()
  {
      objectToShow.setActive(Input.GetKey(KeyCode.S));
  }
}

also activeSelf means "is this exact gameobject active" which is different than activeInHierarchy (since a parent could be inactive)

[swift falcon]

i found the problem i apply the script that i want to appear with s and then the script disable it self when i start the game

but thx for our help

i had another problem how can i cut the yellow circle at the blue line i want to make a car headlight

[modern creek]

with a Mask or SpriteMask component

[ocean hollow]

I'm not sure if this is possible but you might want to look into the "max size" property here https://docs.unity3d.com/560/Documentation/Manual/class-TextureImporter.html

[brittle haven]

I have an assigned sprite variable and I need to reach its sizes (width, height or vector2). I have nothing to do with texture. So I cannot reach maxSize

I throw this sprite into sprite renderer

[swift falcon]

thx

[ocean hollow]

I'm not sure why you said yes when I asked if you were talking about the dimensions of the texture, but you're talking about the scale on the transform component.

In a script, you can modify the scale of a sprite by using gameObj.scale

[brittle haven]

I'm not talking about scale. I need to reach the size of my sprite. for example, if the sprite is 300x300 in size, i need to reach it in the script. I am writing with translation. so i may not be able to explain or understand this right now.

[ocean hollow]

So you are talking about the texture?

Nothing you say is adding up

[brittle haven]

it could be

[ocean hollow]

I need to know what you're talking about before I can help you

You should do some research on unity lingo

[brittle haven]

what do I need to write to get the sizes of this sprite?

[ocean hollow]

Go into your transform component on your object and look at the scale. Play around with that and tell me if that's what you're talking about first

[heady iris]

Are you asking what the apparent size (in world units) of a Sprite would be if you put it into a SpriteRenderer that had a default scale?

Or do you want the actual resolution of the image?

[leaden ice]

Depends what you mean by "size"

[brittle haven]

width and height

or vector2

[tardy crypt]

width and height in world coords?

everybody is saying there's a bunch of different notions of size for a sprite because there's the underlying image which has a resolution in pixels and then the sprite also has a world size which is related but also different than the resolution of the image

[heady iris]

That doesn't answer my question.

[heady iris]

I need to know exactly what you are looking for

Do you care how many pixels are in the sprite?

Or do you care how big it will look in a SpriteRenderer?

[brittle haven]

yes, for its size in the game. Since I am assigning it to a sprite renderer component, I need to get its size

[knotty sun]

spriterender has a bounds property

[golden garnet]

Any ideas for this?

[rigid island]

the code is empty

[ocean hollow]

Imagine it

[mellow grail]

I'm trying to make a game that uses a hexabody like character controller similar to the one so see in boneworks, i cant seem to get the hands how i want them though, they are always to springy and since part of the game will have you use your hands to walk (unoriginal trust me i know) this will make it really difficult to move around, maybe ill add this springy hand feature as a weapon of some kind but for now it would be nice if they were more rigid.

ive tried maxxing out the spring values but it didint seem to help to much

nvm

turns out the sping being high was the issue

[proven lily]

wtf this is so weird

[mellow grail]

what

[golden garnet]

Oh yeah the hastebin link must have expire, I’ll edit with a working link soon

[weary glade]

Hey, can someone help me, im working with the a* Pathfinding assets, and for some reason the seeker just always seems to pick a way through obstacles, any ideas?

[rigid island]

don't crosspost

[weary glade]

What else am i supposed to do if no one responds?

[plucky inlet]

Wait

Research

Test

[rigid island]

yup. its also difficult to help on a specific asset especially if you don't explain any of the setup.

[void turtle]

loving this debugger deadlock

[sleek heath]

Unity in a nutshell:

[void turtle]

It seems to be a feature 😅

[rigid island]

what helps for me is enabling debugging mode in editor first then enable the attach unity

[void turtle]

ok Ill give it a try

[sleek heath]

you know the saying, "it's a feature not a bug"

[rigid island]

just to be clear talking about this one

[compact spire]

Is using addressable assets really worth it? It seems like you can't mix "normal" assets with addressable assets, so that means you have to create a wrapper for any assets from the asset store right?

[spring creek]

What is a "normal" asset as opposed to an addessable asset?

Addressables just create an address for assets so you can load them from that

Either way, definitely a question for #📦┃addressables

[plucky inlet]

Addressables give you different benefits in performance for example. Loading and unloading assets, batching, async handling

[compact spire]

I see, I didn't realize there was a channel for addressables

[heady iris]

If you directly reference an Addressable asset from a non-Addressable asset, you wind up with two copies of the asset

one in Addressable-land and one that isn't

[compact spire]

@heady iris That seems problematic

[heady iris]

I discovered this while I was trying to use Addressables to load all assets of a certain kind into a dictionary

(so that i could avoid manually referencing them or stuffing them into one giant Resources folder)

The really confusing part is that it works fine in the editor

It just fall apart in the build

[spring creek]

Ah ok, I wasn't aware. I need to learn more about addressables before I try to answer anything about it then. Thank you

[compact spire]

@heady iris isn't that what labels are for?

[heady iris]

Asset Labels? I haven't messed with those, actually

[compact spire]

@heady iris If you put a bunch of assets under the same label you can load all addressable assets that match the label.

[heady iris]

Oh, you mean addressable labels. That’s what I was doing :p

But I needed references to the same objects that everyone else had

[compact spire]

ahh

[heady iris]

The addressable-loaded objects were unrelated to the directly-referenced objects

[compact spire]

I'm still trying to wrap my head around the whole thing, but I understand bits of it

or at least I think I do

[visual flare]

CanEditMultipleObject is no more, what's the new flag for that?

[leaden ice]

You have your parentheses wrong

The closing one belongs before the comma

[quartz folio]

Probably worth making less assumptions

[visual flare]

jeez thx

i didn't know you could pile up attributes like this

[leaden ice]

You could also put each in their own [] brackets

Up to you

Hello people, I am new here so, hi.
I am having problems with this while loop that causes the entire unity engine to crash:

private void getNewPosHanger()
{
    float posY = 4.5f;
    bool isLooping = true; 

    while(isLooping)
    {
        float positionEnemySetX = Random.Range(minRangeEnemyHanger, maxRangeEnemyHanger);

        if (!isRayCastPosFull(new Vector2(positionEnemySetX, posY)))
        {
            posNextHangerEnemy = new Vector2(positionEnemySetX, posY);
            break;
        }
    }
}

This function allows me to get a new position for the next enemy on screen, but it checks if that new position is already taken by another foe (that's what the isRayCastPosFull does).
I call this function when the enemy is created an in the start of the gameobject so the next enemy already has their position.

[lean sail]

Go through your code logically and look at the condition of the loop. When does isLooping get set to false?

If that break is never reached itll never exit

[low mirage]

But the thing is that I want to look for a new position if that is already taken. If that position is already taken the while loop should repeat and find a new random position right?

any other ideas on how to implement that behaviour?

[hallow portal]

2d or 3d?

[low mirage]

2d

[lean sail]

🤷‍♂️ depends on the implementation of that method you're using. "Should" but doesnt. You might wanna use an overlap function instead

[hallow portal]

if 2d that this private void getNewPosHanger()
{
float posY = 4.5f;
bool isLooping = true;

while(isLooping)
{
    float positionEnemySetX = Random.Range(minRangeEnemyHanger, maxRangeEnemyHanger);

    if (!isRayCastPosFull(new Vector2(positionEnemySetX, posY)))
    {
        posNextHangerEnemy = new Vector2(positionEnemySetX, posY);
        break;
    }
}

}

something like this

[simple egret]

And add a safety that breaks out of the loop if no valid positions have been found for like 1000 iterations!

[low mirage]

this one is a good one? How can I get the count of the loops?

or maybe with a for loop

[lean sail]

Count how many times its looped or use a for loop

[low mirage]

eh yeah this is the code

[simple egret]

You use a variable declared outside the loop, or a for loop. Either works

[low mirage]

let me try that one

[lean sail]

You should show what that method is doing also. It could be that you're simply returning true all the time so the break never happens

An also, test the method alone so you know it works before using it elsewhere

[simple egret]

Yeah if it always returns true, either the ray is too long, hits something unexpected, or hits the same position every time (if your random min/max variables are identical)

[low mirage]

I don't think it's the problem but you never know, it basically casts a circle in the given position

private bool isRayCastPosFull(Vector2 location)
{
    RaycastHit2D ray = Physics2D.CircleCast(location, 1f, new Vector2(1, 0), layerEnemy);
    if (ray.collider == null)
    {
        return false;
    }
    else
    {
        return true;
    }
}

[simple egret]

layerEnemy is a layer mask, correct? Not a single layer index

[lean sail]

Add a debug, dont assume what it is doing. It's entirely possible the layer is setup wrong, that you have another object (the floor) on the wrong layer. Debug the name of what was hit

[simple egret]

(also that big if statement can be simplified down to a single return ray.collider != null;)

[lean sail]

Another thing I just noticed too is that you are doing a random selection for the X value until one is found. This means theres a very likely chance you are checking the same position over and over.
If you truly need a random place, i would increment x by some amount and check along the entire area. Then return a random index of the areas that were valid

This would save time in the case where only like 1/50 spots were valid

[low mirage]

new info, the check is working just fine, but I will implement this idea, because right now it's looping for a long time a cannot find any avaliable position, even though there are some blank spaces

[low mirage]

this idea

thank you all

[agile carbon]

guys https://youtu.be/CdPYlj5uZeI?t=784 this video mentions splitting the vector into two components. how does it do that? isnt dot product combining not taking apart?

[quartz folio]

Probably worth noting where in the video you're talking about

[agile carbon]

i linked the part

if u press play it starts where im talking abt

[quartz folio]

The dot product is a scalar portion of vector projection

[agile carbon]

if im going to be honest we havent reached there in school, so its going in one ear and out the other. i guess what im trying to ask is how we are supposed to split it up

[quartz folio]

The result of those two dot products is the vector split up into two in the way they're talking about

[agile carbon]

which two dot products. didnt he say in the video we just start off with the orange vector

[quartz folio]

yes, and he shows two dot products

[agile carbon]

which are the blue and red right?

[quartz folio]

The (length of the) white arrows on those lines, yes

[agile carbon]

i guess what im asking is where u get those two lines. i thought the dot product was a combination of two things and in this video you only start off with one thing so i dont get how you split one thing into two

[quartz folio]

the direction the tyre faces and a perpendicular direction to that

[agile carbon]

yes

[quartz folio]

presumably you have the rotation of the wheel, so you can easily get those vectors from that. If you have a transform you can just use transform.forward and transform.right if it's not being rotated around like the wheel visuals

[agile carbon]

like the steeringAngle?

the angle at which the wheel is turned

[quartz folio]

Sure. If you just have an angle then you can use Quaternion.AngleAxis and quaternion multiplication

[heady iris]

neat video!

[agile carbon]

yeah so i have each of the directions, and i have the velocity of that orange arrow. and i have the directions of the blue and red arrows. my problem here is that i need the velocity of the red arrow in order to apply that same force as a centripital force

[quartz folio]

I don't know what you mean, the forward and right directions should be normalized when used in the dot product

and the result of the dot products with the velocity are the components they're talking about

[agile carbon]

i dont understand what this means. i was learning about the dot product but it never mentioned a result of two components only one

[agile carbon]

like without anything related to the dot product i have all three directions and the velocity of the orange arrow and im trying to find the velocity of the red arrow

[gentle glen]

Yo can I ask for help in scripting here?

[quartz folio]

float slidingComponent = Vector3.Dot(velocity, right);
float rollingComponent = Vector3.Dot(velocity, forward);

?

[agile carbon]

so you get the dot product of the velocity of the orange arrow and the right direction and then the same thing of the velocity and the forward direction?

[quartz folio]

Yes

[agile carbon]

ah i see now that makes sense

tysm

[gentle glen]

Yo

[spring creek]

In the #archived-code-general channel? Yes

[gentle glen]

I tried using WorldToScreenPoint on a GO but it always goes to the bottom left

I use a list and an index for the Transform

[spring creek]

Gonna need a LOT more info to help. !code would be a good start

Ahh thanks

if(LockedOn)
        {
            lockOnGraphic.SetActive(true);
        }
        else
        {
            lockOnGraphic.SetActive(false);
        }
        enemyPos = GetComponent<TargetList>().Targets[tgtI].GetComponent<EnemyPosition>().enemyPosition;
        lockOnGraphic.transform.position = camera.WorldToScreenPoint(enemyPos.position);

//This is the defenitions
public Transform enemyPos;
public bool LockedOn;
public GameObject lockOnGraphic;

@spring creek

enemyPosition gets the transform of the enemy GO

[spring creek]

Debug the values of enemyPos

[hexed pecan]

You are using a screen position as a world position

[gentle glen]

it's a public so i can see it in inspector

oh wait

nvm

[gentle glen]

Have any ways for me to change this?

[hexed pecan]

There are ways to set a recttransform's screen space position (assuming that lockGraphic has a recttransform).
I dont remember how though

[gentle glen]

yeah lockOnGraphic is a parent of an image and one slider

[hexed pecan]

This utility class might be of use here https://docs.unity3d.com/ScriptReference/RectTransformUtility.html

[gentle glen]

what i've also noticed is that this code worked perfectly before

and when i used a list getting automatic values it got bugs like that

//List class
public class TargetList : MonoBehaviour
{
    public List<GameObject> Targets = new List<GameObject>();
    public int targets;
    
    // Start is called before the first frame update
    void Start()
    {
        if(GameObject.FindGameObjectsWithTag("GiodEBody") != null)
        {
            Targets.AddRange(GameObject.FindGameObjectsWithTag("GiodEBody"));
        }
        if(GameObject.FindGameObjectsWithTag("EnemyTurret") != null)
        {
            Targets.AddRange(GameObject.FindGameObjectsWithTag("EnemyTurret"));
        }
        
    }

    // Update is called once per frame
    void Update()
    {
        Targets.RemoveAll(s => s == null);
        targets = Targets.Count - 1;
        if(Targets.Count == 0)
        {
            targets = 0;
        }
    }
}

[modern creek]

if Targets.Count is 0, targets will be -1.

If I have a vector that is: (-0.6401844024658203, -0, -0.7682212591171265) would the perpendicular vector be (0.7682212591171265, -0, -0.6401844024658203)?

[agile carbon]

wait so i do a vector and a normalized direction

for my dot product?

[quartz folio]

the velocity is not normalized, the directions should be

[agile carbon]

for the velocity part can i plug in just the vector

cause isnt velocity direction and magnitude like a vector

[quartz folio]

I don't know what you mean, the velocity is a vector that has a magnitude that is the speed

[agile carbon]

ok yeah thats what i was asking. so i just dot the orange vector in the video with the normalized direction of the red right?

[quartz folio]

Yes

[agile carbon]

and that returns the blue vector with its magnitude and and direction?

or wait.

[quartz folio]

No, it returns a magnitude

[agile carbon]

oh a magnitude of the red?

[quartz folio]

👆

[agile carbon]

kk and the magnitude of the red and blue arrows are the same

jeez vectors are interesting

will i learn this in AP physics? 😭

[hollow crane]

I think they do a little bit w vectors in AP

it’s mainly calc 3 tho
