the DialogCallBackData class defined at the top should hold a reference to a dictionary, and i want the DialogEventCallback method defined at the bottom, to change the dictionary in the method PlayDialog on line 70
https://hatebin.com/bywlmqltus

dont worry about it.

[burnt vapor]

So again,

Optionally take the boolean result from Remove and see if it return true. If it's false there was no instance found

I'm not sure why it would not remove it, though? What do you think might happen?

[vast vessel]

havenbt worked with refrances before

i just kinda slapped a ref prefix in my class constructor

[burnt vapor]

Well you definitely don't need to use pointers

And rarely do you need ref

[vast vessel]

oh pointers!

[vast vessel]

why not?

sounds like the way to go now that you mentioned it

[burnt vapor]

Because C# is a managed language and most things are reference types

Pointers are mostly only used when you communicate with a language that exposes these

[vast vessel]

the only place that i am using pointers in the code i sent are required by the fmod plug in im using

[burnt vapor]

So in the case of EventInstances you have a Dictionary with a string key and object value. The value is a reference type.

If you have this exact reference type then you can do comparisons by reference, which is the defualt in C#. If you remove items from a Dictionary you can specify the unique string key otherwise

It's hard to determine where callBackData comes from here since you used a pointer but considering you don't seem to instantiate another reference this should remain the same reference

Only with value types this is different, as a copy is returned instead. This is usually what C and C++ does with everything unless you start using pointers

[vast vessel]

seems like it worked!

no crashes!

the reason i got crashes was that the plugin required me to have DialogEventCallback be a static method, and i didnt know how to pass my data to it when it was static

since i couldnt add any new params to the method

so i had it be private and it crashed the editor

[burnt vapor]

I don't get why that would crash, weird

[echo matrix]

yooi

[burnt vapor]

Would it make sense to use an event instead so you don't have to specify a callback?

[echo matrix]

what are some good free lip sync solutions

i am using cc4 model

[vast vessel]

i dont either. havent got a respond to my post on the forums of the package im using

[vast vessel]

i thought that too but ya know... its not my package

its a package that integrates the fmod audio engine into unity

and thats how fmod, which is a seperate program interacts with unity

[thin river]

Hello, I am really stucked now 😄

I have two scenes. Where one is showing the loading progress bar, that shows % and loading text. The second scene is the main game scene.

I was thinking that I can load the game scene asynchrounously and set operation scene activation to false and receive the information from game scene in loading screen (Like the game scene will be reporting the state of loading...).

(Context info - I don't want to simulate it - as I am generating the map procedurally so I want to report real status of the loading).

But I cannot do that with this approach, as Awake / Start methods are not launched until the scene is activated.....

Can I somehow have two scenes that will be communicating while loading ? Or this is completely wrong approach?

(My next idea is to merge these two scenes and just create loading handler.... but I don't like this idea - I will do it nly when I must to 😄 )

[thin river]

Ok Nevermind!!!

I found out I can load it with Additive flag:
↓
SceneManager.LoadSceneAsync("Game", LoadSceneMode.Additive);

So I can still have my loading scene active... and the Game scene too 🙂 Than handle manually switching the scenes!

[willow scroll]

Please, don't cross-post.

[tawny bolt]

ok

wont happen again

[willow scroll]

Also I have never seen someone sending an image of their question

[lethal bolt]

How can i do this so it works on an prefab. I dont know how to get the gameobject of an canvas text.

i know i have to get component but i can seem to find out how

[buoyant knot]

first, you should probably finish everything before you call for something’s own destroy

if you need to work on a prefab, you need a reference to its gameobject instance

i assume you want to work on the instance, and not the prefab file itself

when you instance a prefab, Instantiate returns a reference to the thing you just instantiated, which you can use

[verbal dome]

Destroy happens at the end of the frame, not instantly

[buoyant knot]

but doesn’t it call OnDisable instantly?

i forget about that part, because OnEnable is definitely called from one line to the next

[lethal bolt]

Is the canvas called an gameobject?

or can i use public gameobject on it?

[buoyant knot]

the canvas is a component, which is on a gameobject

[lethal bolt]

oh

[verbal dome]

Does it? Idk, the docs say this:

When destroying MonoBehaviour scripts, Unity calls OnDisable and OnDestroy before the script is removed

[buoyant knot]

ambiguous wording as always

[verbal dome]

I dont think it means it happens immediately

But yeah ambiguous

[buoyant knot]

it sucks to have the documentation, and still need to test to find out the details

it took me the longest time to figure out that Awake gets called, then OnEnable gets called, all one line to the next, but Start might get called next frame

[verbal dome]

Yeah I think that depends on which stage of the playerloop you instantiate an object

[swift crag]

It's consistent with when instantiation and destruction actually happen

Instantiation happens immediately (otherwise it would not be very useful)

[lethal bolt]

Is there an diffrent approach that works?

[swift crag]

read the error

you're trying to assign a Text into a GameObject variable

don't do that; make a Text variable if you want to store a Text

[magic panther]

https://hatebin.com/lgsrbwyytb

Movement works fine, but the rotation applied in the LateUpdate is extremely tiny, like 0 to 1 instead of 0 to 360 tiny. What could be causing this?

[lethal bolt]

I see the error. but im trying to change the text using an prefab so i couldnt do i the "Easy way"

[swift crag]

that doesn't make any sense

[lethal bolt]

wdym

[swift crag]

oh, you mean you can't just serialize a reference

[swift crag]

bceause you're instantiating a prefab with this component on it

[lethal bolt]

This would work

The enemy adds 1+ score each time it goes out

oh.. hold up

[lavish jolt]

Hello! I have 2 scripts where I set camera rotation. First is FPS Mouse Look and second is camera shaker. How can I combine them to work togather. Now CameraShaker dosen't work at all, because MouseLook every frame sets rotation

[swift crag]

I would store the camera shake separately from the actual camera rotation

Alternatively, apply it after the camera gets rotated, and have it just adjust the current rotation

You could use an event for this

[lethal bolt]

Why cant i add the Text Component into ScoreText?

[swift crag]

public event System.Action<Transform> OnCameraRotated;

public void RotatePlayer(Vector2 delta) {
  // ... 
  OnCameraRotated?.Invoke();
}

[swift crag]

didn't you just say that you're using a prefab here?

or is this now in the scene?

[swift crag]

Then, in the camera shaker:

[lethal bolt]

I swiched because the player isnt an prefab so its easier..

[swift crag]

void OnEnable() {
  mouseLook.OnCameraRotated += DoRotation;
}

void OnDisable() {
  mouseLook.OnCameraRotated -= DoRotation;
}

void DoRotation(Transform cam) {
  // mess with the camera here
}

[swift crag]

You would calculate the shaking as usual, but not actually do anything until DoRotation gets invoked by the event

[swift crag]

Does ScoreText actually have a Text component on it?

Show its inspector.

[stoic spear]

if you are using TMP you need to put using TMPro and make it a TMP_Text type not Text

[swift crag]

That's not a Text

that's a TextMeshProUGUI

[swift crag]

so, yes, do this

[lethal bolt]

Oh.

Thanks you both (:

my character keeps spamming left and right when i stand to the left of it. The console is only printing "TURN LEFT" yet the scale is being spammed between -1 and 1.

[stoic spear]

okay well first of all, i would suggest against using smoothdamp to move the camera

if its a first person game

instead you can use the mouse delta and just += the local rotation, then you wont be setting it just adding to it

here is my view calculation:

    Vector2 cameraAngles
    private void CalculateView()
    {
        inputView *= sensitivity / 10;

        cameraAngles += inputView;
        cameraAngles.y = Mathf.Clamp(cameraAngles.y, -90, 90);

        Quaternion camRot = Quaternion.AngleAxis(-cameraAngles.y, Vector3.right);
        Quaternion playerRot = Quaternion.AngleAxis(cameraAngles.x, Vector3.up);

        camHolder.localRotation = camRot * Quaternion.Euler(camRecoil);
        transform.localRotation = playerRot;
    }```

and then in the shake, you can just camRecoil += shakeRotation (or maybe you want to change the name to camShake

[gleaming kraken]

hey guys, so im trying to make the paddle stop the moment that it's on the same y axis as the ball, but for some reason, it still passes by the ball no matter what. Why is this the case?

[languid spire]

never test floats for equality, I'm sure you've been told this before

[gleaming kraken]

ohhhhhh

thank you

[swift basalt]

can someone help me understand this? im new to namespaces and unity in general. LevelData is part of the same namespace.

[languid spire]

you are missing a class declaration

[swift basalt]

what does that mean? I declare level data in a different file

[swift crag]

that merely means that LevelData exists

the problem is that SaveMap isn't being declared inside of a class

thus the error

[languid spire]

spot the difference. This has a class declaration, the previous shot does not

[swift basalt]

Should I put it inside of the LevelData class? it is for taking a Tilemap and outputs a LevelData

[swift crag]

It could be a static method of LevelData, or it could be a static method in another separate class.

[languid spire]

put it where you want, just follow the syntax of c# when doing so

[stoic spear]

yeah i was gonna say you might want to make that static, so you dont need a specific instance to call it

[swift crag]

otherwise, you'd need to do something very silly like new LevelData().SaveMap(...)

[zealous hatch]

if (PlayerPositionX < gameObject.transform.position.x) {
   transform.localScale = new Vector3(-transform.localScale.x, transform.localScale.y, transform.localScale.z);
    Debug.Log("TURN LEFT");
}
else if (PlayerPositionX > gameObject.transform.position.x)
{
        
          
    transform.localScale = new Vector3(transform.localScale.x, transform.localScale.y, transform.localScale.z);
    Debug.Log("TURN RIGHT");
}```

Nothing else changes the local scale... but the gameobject keeps switching between -1 and 1 when standing to the left of him

[dense crater]

Hi I have a quick question. Im using visual studio as my ide and for some reason syntax highlighting and tool tips just turned off for one of the files im using? It still compiles fine. I don’t know if this is the right place to ask this but any help would be greatly appreciated

[swift crag]

which would then return a second, unrelated LevelData

[swift crag]

do you see "Miscellaneous Files" in the top left corner?

or do you see "Assembly-CSharp"?

[dense crater]

I have miscellaneous files

[swift basalt]

can i make it so you can do Tilemap.SaveMap()? or would i have to edit the tilemap code

[swift crag]

Actually, yes, this is possible.

[stoic spear]

im pretty sure you can extend unity classes, yeah

[swift crag]

It'd be an extension method

[swift crag]

Close VS, regenerate project files (preferences -> external tools), and then reopen VS

[swift crag]

public static class TilemapExtensionMethods {
  public static LevelData SaveMap(this Tilemap tilemap, int id, LevelData levelData) {
    // ...
  }
}

I wouldn't make this return LevelData, since it's just modifying the LevelData you pass to it

either way, you'll use it like this:

tilemap.SaveMap(123, someLevelData);

[swift crag]

Note that the name of the class doesn't matter

the magic is in the this keyword

[dense crater]

Hmm clicking that button doesn’t seem to start any file regeneration as far as I can tell when I press it. After reopening the issue still remains

[swift crag]

Is there anything unusual about where this file is located?

what's the path to it?

[dense crater]

Currently it’s just sitting at the top of my assets folder

[languid spire]

go into your project folder with file explorer and delete all .sln and .csproj files

[swift crag]

yep, that's the next move

I had an issue once where Unity somehow wrote duplicate entries into the .csproj files

and I had to completely delete them to fix the problem

[dense crater]

That’s so weird, I imagine y’all are right because moving it to a sub folder fixed the issue.

If it comes up again I’ll try what y’all said, thanks a bunch!

[karmic isle]

Hey quick question, ive recently finished a tutorial for unity so right now i can move my character left and right

id like to make my character run if i tap left or right twice

im thinking in order to do that I'd need to make a seperate movement script and somehow find a way to where if i tap left twice or right twice my character moves faster

Id like to test myself so pls dont give me the answers but nudge me in the right direction y'know?

[stoic spear]

might want to take a look at the new input system 👀

[swift crag]

I would not make a separate movement component, but I would add some extra logic to the existing one

[dense crater]

State machines

[karmic isle]

oooohhh

[karmic isle]

theres a hwat!you're talking about the input manager?

[frosty hound]

It's a new (not really, it's current now) way to handle input using events. It's not beginner friendly, and if your'e just learning, doing it the way you're handling it now is probably a better learning opporunity; modifying existing logic etc.

But you wouldn't separate it no, as above, you'd modify the existing movement logic that tracks if you've pressed the direction twice.

[stoic spear]

it has a way to set up double-press events very easily

otherwise i’m sure you could figure something out with a timer that checks for a second input within the time

[summer stump]

A coroutine and waitUntil works well for that

[stoic spear]

or timer -= time.deltatime every frame

[stuck crystal]

Hey, can anyone tell me what I'm doing wrong?
I am trying to make the jumps increase every 2 seconds but not surpass 2.

[stoic spear]

i would use InvokeRepeating for this, its super useful and you can just give it the name of a method and how often you want it to be called

i used that for a regenerating health system

[stuck crystal]

Alright, thanks.

[timid oriole]

how can I have this code calculate the playercolliders bottom & center of the collider (Physics.Raycast(playerCollider.transform.position, Vector3.down, out RaycastHit hit, 0.2f))

I know I use bounds.min I think but not sure where to fill it in exactly

[polar acorn]

You want to freeze the game for 2 seconds every time this runs?

[summer stump]

Well yes, I was suggesting a better method that that

[stuck crystal]

I tried googling stuff and that's what it gave me.
My brain is melting from listening to brainrot in VC.

[karmic isle]

oh this is why harder than i thought it'd be

words have new meanings

[stoic spear]

why is a coroutine better

[summer stump]

Waituntil second input is very readble and clean

Better may not be the right word, just cleaner

You mentioned one and made it seem negative

[stoic spear]

fairs, i just dont like making a whole seperate method like that if i dont need to

[summer stump]

So I suggested a nice alternative

[summer stump]

I prefer to break down code as much as possible

[karmic isle]

dumb question, any reason why theres two horizontal and vertical options?

[polar acorn]

As in multiple bindings for the same input? Expand it and you should see places to add more bindings

[stuck crystal]

The more the better.

[timid oriole]

RaycastHit hit;
if (Physics.Raycast(playerCollider.bounds.min, Vector3.down, out hit, 3))

Not to sure why this is not working I'm trying to use it as a ground check

3 is the raycast max btw

[polar acorn]

Try using Debug.DrawRay with the same start and direction to see where your ray actually is visibly and see if it's where you expect it to be

[timid oriole]

Okay I'll check

I can just shove it under the physics.raycast line right?

[polar acorn]

I'd put it above the raycast line

So it isn't conditional based on the raycast hitting anything

https://docs.unity3d.com/ScriptReference/Debug.DrawRay.html

[timid oriole]

why is it asking me for two colors?

Just wants me to say Color.Red?

nvm

oopsi

Should I say bounds.center maybe instead

[stoic spear]

you should be able to use the player transform position, but i guess bounds.center works as well

[timid oriole]

I'm trying to have the origin be the collider not the empty game object player though

do you mean playerCollider.transform.position?

[stoic spear]

why?

[polar acorn]

That would probably work, unless your collider's center is offset

[timid oriole]

to detect for ground

[polar acorn]

You could also just create an empty child object whose sole purpose is to let you position the raycast origin in the inspector, and use the position of that

[timid oriole]

if (Physics.Raycast(playerCollider.bounds.min.y, Vector3.down, out hit, 3)) getting an error argument cant convert from float

[stoic spear]

are you using rigidbody or character controller for movement?

[timid oriole]

this says bottom of collider on y axis

yes

[polar acorn]

Yes, because playerCollider.bounds.min.y is a float, not a Vector3

[timid oriole]

the y is a float?

[stoic spear]

which one

[timid oriole]

Rigidbody

[stoic spear]

kk

[summer stump]

All the components (x, y, and z) are floats

[timid oriole]

Yeah

[summer stump]

Except in Vector2Int or something, where they are int

[stoic spear]

i would have the player origin point to be at their feet if it isnt already

[timid oriole]

Is there no way to do it from the collider and using bounds.min?

[stoic spear]

i mean there is

[summer stump]

Yes, there is

[stoic spear]

which object is your script on?

[timid oriole]

the player

its an empty object whihc I called the playerCollider and dragged and dropped it so I have reference to it

[stoic spear]

if you got the center of the collider and the player position, they should be the same no?

[timid oriole]

I guess so yeah

[stoic spear]

im confused now, can you send a sc of the hierarchy?

[timid oriole]

Yeah I will

[stoic spear]

i dont know if the script is on the parent object or a child

[timid oriole]

on the parent

[stoic spear]

right ok

[timid oriole]

And I guess I didn't do it the way I normally do its all only the mesh

[stoic spear]

looks okay, what is the problem currently?

[timid oriole]

Error message

[stoic spear]

try bounds.center

instead of min.y

[timid oriole]

okay

do I just have to make it bigger then to reach the ground

[stoic spear]

looks good, yeah you might need to extend it 0.1 or so

[timid oriole]

I adjusted it and it didn't change it at all

[crisp oyster]

Hello

[stoic spear]

did you change the debug ray as well?

[crisp oyster]

As-salamu alaykum everyone 🥰❤️🫂

[timid oriole]

yeah

oh no

i didnt

yep now I did same thing still

[stoic spear]

though this works, if you are on a steep slope with a capsule collider the center of your collider will be a bit off the ground meaning the raycast wont hit the ground. i dont know how to fix this issue and it led to me using CharacterController instead

[stoic spear]

still broken?

[timid oriole]

I don't think it works my character is now flying upwards slowly

When I hit space at least

[stoic spear]

does the ground check work before you press space?

[timid oriole]

yeah

It says I'm grounded but never updates it though

[stoic spear]

might wanna take another look at the gravity/jumping code

[stoic spear]

so when you start flying upwards it still says grounded?

[timid oriole]

yes

But if I disable it while in air and land again it sets it to grounded

[stoic spear]

its in update() right?

[timid oriole]

yes

my movement though is in fixed

[stoic spear]

should be alright

[stoic spear]

seems like rb doesnt have gravity on

[timid oriole]

oh yeah

I disabled it I forgot when testing the ray

[stoic spear]

and it could be that you arent jumping high enough to get 5 units of clearance for the raycast

check in scene view with the debug line

[timid oriole]

I can jump now fine but I'm able to double jump

the debugline no matter the raydistance I set is the same

[stoic spear]

oh, yeah that method is different. instead of putting 5 at the end of the parameters, just multiply Vector3.down *5

[timid oriole]

ill try it

[swift crag]

DrawRay takes a position and a displacement

[willow scroll]

Both Physics.Raycast and Debug.DrawRay take float distance as their parameter

[stoic spear]

oh

wonder why it isnt working then

[willow scroll]

Not sure what's not working

[stoic spear]

maybe debug drawline(collider.center, collider.center + (vector3.down*5))

with 2 points

[timid oriole]

I can jump infinite now

[willow scroll]

Why? It's the same as their DrawRay method

[slender bridge]

public static void DrawRay(Vector3 start, Vector3 dir, Color color = Color.white, float duration = 0.0f, bool depthTest = true);

[willow scroll]

What's your objective?

[stoic spear]

yeah but apparently drawray isnt working

[swift crag]

DrawRay does not take a distance.

[timid oriole]

groundcheck

[swift crag]

the fourth parameter is the duration of the ray

[slender bridge]

https://docs.unity3d.com/ScriptReference/Debug.DrawRay.html

[willow scroll]

Oh, you're right

[signal sonnet]

can someone explain to me what the lamda here is for ?

public void MoveTo(int targetScene, int targetSpawn)
        {
            Pause();
            SaveSystem.SaveSceneData();
            UIHandler.FadeToBlack(() =>

                {
                    m_IsTicking = true;
                    
                    foreach (var active in m_ActiveTransitions)
                    {
                        if (active.SpawnIndex == targetSpawn)
                        {
                            active.SpawnHere();
                            SaveSystem.LoadSceneData();
                        }
                    }
                    
                    UIHandler.SceneLoaded();
                    UIHandler.FadeFromBlack(() =>
                    {
                        Player.ToggleControl(true);
                    });
                };
            });

            
        }

[stoic spear]

not on both, only on debug

[timid oriole]

the mulitply?

[stoic spear]

first version with the parameter of 5 is good for raycast

yeah

[willow scroll]

Is there any reason for not using OnCollisionEnter & Exit?

just use CharacterController

[timid oriole]

Idk

I don't like character controller very much because my character can't use physics

like If I want to throw an item based off my current velocity I don't think u can do that

[willow scroll]

The reason why it might not work is you not even using a LayerMask. If your player has a Collider, this is what the Raycast is going to detect and set the boolean to false.

[stoic spear]

yeah, depends on the game you want obviously

[willow scroll]

This much should be enough to fix it, but I would rather you used the methods I've previously mentioned.

[stoic spear]

i wonder if its possible to still do collision checks with having a rigidbody and a charactercontroler

[karmic isle]

alright chat im stumped, how would I make it to where if i double tap left or right mmy character would run? here's my code if you need it

[willow scroll]

It is, but it doesn't make sense

[timid oriole]

[stoic spear]

how would i make myself able to push boxes with a cc do you know?

[karmic isle]

you want me to paste my code and send it back or smthn?

[timid oriole]

Don't think you can because Cc doesn't have physics built in no? you are simply just moving the object

[stoic spear]

yeah, but there might be a way

[karmic isle]

I SHOULD JUST READ

[willow scroll]

I think they both are just going to detect the collisions at the same time

[timid oriole]

Question and might be silly

Can two objects if only one has a rigidbody collide?

assuming they both have colliders

[willow scroll]

Surely

[polar acorn]

Collision requires a rigidbody on at least one of them yes

[timid oriole]

So even mesh colliders then?

because they just fall through my map

[rich adder]

only convex

[stoic spear]

OnControllerColliderHit{
if (hit.getcomponent<rigidbody>{

whoops

[stoic spear]

by just getting the direction you hit it in and doing AddForce()

[timid oriole]

holy moly one sec

[stoic spear]

so you wouldnt be losing anythign with cc, and it has a super robust ground check

[timid oriole]

I have this but doesn't work still

[timid oriole]

Oh interesting

[stoic spear]

v simple

[timid oriole]

oh damn yeah

still prefer rigidbody tho :p

[rich adder]

what doesn't work ?

[stoic spear]

damn, you can even make it go flying by increasing the magnitude and stuff lol

[timid oriole]

covex it still clips through the map

[rich adder]

which one has convex the rigidbody ?

[timid oriole]

the items

because they fall from the sky

at random vector on start

[rich adder]

ok, and they have colliders ?

[timid oriole]

yesh mesh colliders + covex however the ground is a mesh collider without a covex

[rich adder]

thats fine

[storm pine]

Basically this: https://discussions.unity.com/t/how-do-i-make-a-double-tap-system-for-dashing/54630

[rich adder]

is any of them marked "isTrigger"

[timid oriole]

nope

but they fall at a quick pace could that cause it?

[rich adder]

na, do you have scripts moving it

[timid oriole]

no scripts moving it just instantiating

[rich adder]

can u show whats happening

[timid oriole]

yeah ill record

[karmic isle]

thank you

[storm pine]

No problem, since Unity has a big community is very easy to find common functionality and mechanics on Internet

[timid oriole]

how do I record haha

I'm trying to use the amd thing but It's not working

[rich adder]

something like OBS or the built in recorder with Windows key + G

[whole parcel]

hey guys! i was working on a pacman game but my pathfinder kinda seems off. can someone take a look at it?

[rich adder]

lol what is happening here ? its hard to tell

[whole parcel]

try and see?

[timid oriole]

the items are falling through the map

some of them are

[rich adder]

so the player stays on the ground? is just the items ?

[timid oriole]

player no issues

its the items yeah

[summer stump]

Generally best to just provide the information instead of asking if anyone can help

[rich adder]

try turning out their collision detection to Continuous

[timid oriole]

dynamic

or just continous

[rich adder]

continuous

also can you show the spawning script ?

[timid oriole]

that

fixed it

Does deactivating an object make it "lose" its instance?

[languid spire]

no

[digital kelp]

This script is on a ui toolkit document, and I make it deactivate out of the way at the start
Then when I need it, it gets activated and I can interact with the UI element and its buttons
However the buttons dont work after reactivation

When I just leave it activated from the start the buttons work

But not after having being deactivated and then reactivated

might want to go through some c# crashcourse

[karmic isle]

no I dont believe so

[polar acorn]

Why not

[polar acorn]

why did you put it there

[karmic isle]

might need to, I went through one tutorial and i realized how little it actually taught me

[karmic isle]

i was copying off a forum

[rich adder]

yeah maybe its time because this is pretty basic stuff

[polar acorn]

Pretty sure the forum didn't put it just floating in a class

that'll be the pathfinder logic!

the positioning of my grid is also kinda wacky

i feel like the path finder logic is mainly correct, and moreso a problem w my grid

and how i process it in code

[bleak glacier]

Is there an equivalent to public Rigidbody2D myRigidbody; but for circle colliders? I don't see any other way to make a script reference a circle collider.

[brazen wigeon]

Does anyone know how to make a code for moving our characters up, down and left to right, but using Android buttons specifically for mobile games, I've followed chatgpt but there are still errors like the character doesn't move or the code is an error, but it's the same as what is displayed on chatgpt.

Honestly, it is very difficult to find sources of inspiration, especially on YouTube, and in my area there are very limited people who understand game making, especially for mobile games

[bleak glacier]

I'm trying to detect a click on a sprite and I've only found half finished explanations. I'm assuming I need to use a circle collider but I can't find a way to reference it to be able to detect the click with a script.

[wintry quarry]

When you say "on a sprite" can you be more specific?
Sprites are assets, they don't exist in the game.

You'll have either a:
SpriteRenderer
or
UI Image

[warm condor]

Hi guys, I have this line of code ,and several others that are like it, that applies a velocity on the player using the rigidbody2d (for example, the walking code is rb.velocityX = 4 * MovementDirection; ). My issue is that I have this line of code in the FixedUpdate() function, and when I run the game and I walk, the speed that I am going is 3.74... This doesn't happen in the update function, so what could be the problem?

[wintry quarry]

friction probably.

[bleak glacier]

It's a sprite render. I just need to detect a click on that sprite render. Idk how though

[wintry quarry]

So yeah you can't detect a click on a Renderer. What you need is to attach a Collider2D to it.
Then you can either use OnMouseDown or IPointerDownHandler (which needs some extra setup too if you go this route)

[warm condor]

is there a way I can turn that off? I already have a function that will make the player slowly stop when not moving.

[wintry quarry]

yes you can use a custom physics material with no friction

Also double check if you have drag/linear damping on the Rigidbody

[polar acorn]

The exact same thing but you get a CricleCollider instead of a Rigidbody2D

[bleak glacier]

It doesn't work. I've tried it

[wintry quarry]

CircleCollider2D

it works just fine

[polar acorn]

https://docs.unity3d.com/ScriptReference/CircleCollider2D.html

[whole parcel]

@rich adder were u able to see smth?

[warm condor]

ah yes you were right. I changed the values and I got the expected value. Thanks!

[bleak glacier]

Weird. I must have done something wrong. Thanks!

It works now

Maybe a typo

[wintry quarry]

definitely.
Note there's nothing special about Collider2D or Rigidbody2D. This is the same process you use to reference ANY component or asset in Unity

i hv the positioning for all of these nodes. is there a way to place a one by one square to check if it's being mapped to the right positioning through code?

[wintry quarry]

write a for loop and instantiate objects in a grid?

[whole parcel]

objects?

[wintry quarry]

yes objects

for example a prefab of a "square"

whatever that means to you

perhaps a cube MeshRenderer or a SpriteRenderer

debug.drawline?

No, you will not. Not really

You may see patterns, but underatanding takes more

[hollow forum]

Im trying to code a simple orbit simulation but im not sure how to actually apply the force to the external planet

i saw something about some addforce methods or sm but idk

this is my current code

[wintry quarry]

I recommend watching this https://www.youtube.com/watch?v=7axImc1sxa0

you definitely don't want to use Update.

[hollow forum]

i have watched this video already

but was kinda confusing

[wintry quarry]

what part are you confused by

[hollow forum]

how to actually apply the force i have calculated using code

i saw online about a rigidbody.addforce

[wintry quarry]

That's covered in the video, though he doesn't use Rigidbodies

but yes for a Rigidbody, you use AddForce to add forces, naturally.

[hollow forum]

it just doesnt show up when i try to add it to a rigidbody

[wintry quarry]

wdym by "it doesn't show up"

[hollow forum]

on the intellisense

but i just typed it manually and it seemed to have worked

[wintry quarry]

that sounds like a problem with your intellisense

is your IDE configured properly?

[hollow forum]

i just followed a tutorial on how to set up vscode for unity

[swift crag]

if you don't see this in the bottom left corner, it's not working properly

(well, not that exact project count, but you need to see "Projects: ")

[whole parcel]

my pathfinder seems to be working fine when i turn off my walls tilemap. but when i turn it on, it seems to get "stuck" in the walls. why can that be?

[swift crag]

perhaps the wall tilemap has a collider

[wintry quarry]

well if the "walls" has its own collider... they'll collide with it

[whole parcel]

it has a tilemap collider

[hollow forum]

what allows me to see projects in the bottom left

[whole parcel]

but i gave it a no friction material

[wintry quarry]

Doesn't seem too mysterious then

[hollow forum]

cause i had it before with this but it wasnt working

[wintry quarry]

Why should the ghosts be interacting with that collider at all

just use layer based collisions and disable the interaction entirely

[whole parcel]

ayoo

that fixed it

tysmm

[hollow forum]

does a AddForce only take two arguments?

and is it a vector2 or just a value

[short hazel]

Depends, there are multiple overloads (version of the method) available. Check the documentation to see what's available.

[hollow forum]

i read that it takes the x and y value of the force then adds that to the rigidbody

but doing that gives me an error

[short hazel]

2D or 3D rigidbody?

[swift crag]

and what is the error..?

[hollow forum]

2d rigidbody

no overload method for Addforce takes 3 arguments

[short hazel]

Yeah so this one only has one overload available. It takes a Vector2, and optionally a force mode

Two arguments maximum

[swift crag]

ah, it doesn't have a separate overload for separate x and y forces

[hollow forum]

ok i had also a vector 2 with both combined forces

[polar acorn]

https://docs.unity3d.com/ScriptReference/Rigidbody2D.AddForce.html

[hollow forum]

ive got the force working and its moving

but my forces are staying constant even though the distance from the planet is changing

        ```

[errant niche]

i just started programming with unity and watched some tutorials, and they all did these 2 lines of code for movement. I dont understand what this exactly does, can someone explain it to me please?

[rocky canyon]

GravitationalConstant * (rb1.mass * rb2.mass) / (distance * distance);

OH MY GOD

[rocky canyon]

pretty sure u need to square the distance (seperately)

[hollow forum]

YEA I DID I FORGOT THE BRACKETs

[wintry quarry]

It reads input for the horizontal and vertical input axes and just stores the input data into variables.

It doesn't do anything else.

[languid spire]

no need to shout

[hollow forum]

sorry

but its now doing weird things lmao

[errant niche]

so if i add a rigidbody force to the left by an if statement which detects if i press a, does it just read the input for that and store it or are these two not associated?

[wintry quarry]

the code you showed has nothing to do with Rigidbodies or forces

it's literally just reading the input data

and putting it in a variable

[errant niche]

what inputs though?

[wintry quarry]

The axis named "Horizontal" is going into a variable named horizontalInput

[timid bridge]

For example W = 1 S = -1

[errant niche]

that makes sense

so its just the location of the object that is put into the variable?

[wintry quarry]

By default this, but you can change it

[wintry quarry]

there is no object

[errant niche]

right

[wintry quarry]

it's just detecting input from input devices

i.e. keyboard/gamepad

nothing to do with object locations or anything like that

[errant niche]

and what exactly is horizontal or vertical input?

i dont really understand that

[wintry quarry]

Whatever you define it as

[errant niche]

ok

[wintry quarry]

by default "Horizontal" is the D and A keys on the keyboard

and left and right on a joystick

[errant niche]

oh ok thats what i didnt know thanks

[timid bridge]

You can look it up and change it here

[wintry quarry]

but you can change it to whatever you want

[errant niche]

i just started programming with unity so thanks for helping me

[wintry quarry]

Oh also the arrow left/right keys on keyboard

[errant niche]

ok thanks

[timid bridge]

and joystick

[wintry quarry]

It may help to read this https://docs.unity3d.com/Manual/class-InputManager.html

[errant niche]

so vertical is just a and s?

[errant niche]

ok

[rocky canyon]

w and s

and up and down arrows

[errant niche]

yeah

[wintry quarry]

W and S

[errant niche]

ok thanks

[errant niche]

thats what i meant i just wrote the wrong letter

[rocky canyon]

check out this screen @errant niche

[errant niche]

if i edit the name to something else, will i also need to do

Input.GetAxis("newName")?

[rocky canyon]

yes

[errant niche]

ok

[rocky canyon]

like if add a new Axis called TurretDirection

Input.GetAxis("TurretDirection");

[errant niche]

ok thanks now i understand

if i press w or upArrow, what exactly gets saved in the variable ?

[rocky canyon]

one... [1]

[errant niche]

and if i press s?

[rocky canyon]

and if u press down its -

[wintry quarry]

Why ask us

You can cehck for yourself

[errant niche]

ok

[rocky canyon]

1 and -1 but u can debug these values ^

[errant niche]

thanks

[rocky canyon]

same with A - D left is -1 and right is +1

[errant niche]

is it a good idea to use these values to make movement?

[wintry quarry]

var test = Input.GetAxis("Horizontal");
Debug.Log("Horizontal is: " + test);```

Get used to using Debug.Log to test things

[wintry quarry]

of course

[errant niche]

ok

[rocky canyon]

thats how ive always done it

[errant niche]

ok thanks so much for the help

[errant niche]

now it makes so much more sense to me why everyone uses it

[rocky canyon]

fast and easy

[errant niche]

yeah

[rocky canyon]

        // Check for W key input (move forward)
        if (Input.GetKey(KeyCode.W))
            moveDirection += Vector3.forward;

        // Check for S key input (move backward)
        if (Input.GetKey(KeyCode.S))
            moveDirection += Vector3.back;

        // Check for A key input (move left)
        if (Input.GetKey(KeyCode.A))
            moveDirection += Vector3.left;

        // Check for D key input (move right)
        if (Input.GetKey(KeyCode.D))
            moveDirection += Vector3.right;```

way better than garbage like this ^

[errant niche]

thats what i did in the beginning

[rocky canyon]

lol me too

but u learn quickly why its bad

when u can use 2 input axis's for 4 degree's of movement

w/o needing 4 if statements

[errant niche]

yeah much better

with my orbital simulation

the orbiting particle just flies away and leaves and im not sure why

{

    public GameObject Planet2;
    public float GravitationalConstant;
    public float distanceX;
    public float distanceY;
    public Rigidbody2D rb1;
    public Rigidbody2D rb2; 
    public float forceX;
    public float forceY;
    public Vector2 totalForce = new Vector2(0, 0);

    
    void Start()
    {
        
    }
    
    // Update is called once per frame
    void Update()
    {
        rb1 = Planet1.GetComponent<Rigidbody2D>();
        rb2 = Planet2.GetComponent<Rigidbody2D>();
        
        distanceX = (Planet1.transform.position.x - Planet2.transform.position.x);
        distanceY = (Planet1.transform.position.y - Planet2.transform.position.y);

        if (distanceX < 0){
            distanceX = -distanceX;
        }

        if (distanceY < 0){                                                     
            distanceY = -distanceY;
        }       

        if (distanceY == 0){
            forceY = 0;
        } else {
            forceY = GravitationalConstant * ((rb1.mass * rb2.mass)/(distanceY*distanceY));
        }

        if (distanceX == 0){
            forceX = 0;
        } else {
            forceX = GravitationalConstant * ((rb1.mass * rb2.mass)/(distanceX*distanceX));
        }


        totalForce = new Vector2(forceX, forceY);

        rb1.AddForce(totalForce, ForceMode2D.Force);
    }
}```

this is the code

[wintry quarry]

for one you should not be adding force in Update

only FixedUpdate

for two - why have two separate references?

    public GameObject Planet1;
    public GameObject Planet2;
    public Rigidbody2D rb1;
    public Rigidbody2D rb2; 

Why not just delete the GameObject one and use rb1 and rb2 exclusively?

You can assign them in the inspector

for 3 - Add some Debug.Logs to see how much force you're actually ending up adding

[hollow forum]

im not sure how to access the position for the other planet

i can see the force cause it changes in the inspector

[languid spire]

never test floats for equality

[hollow forum]

what does that mean

[wintry quarry]

rb1.position rb2.position

[rich adder]

if(float == float) is a bad idea
floats are approximate numbers they are not precise.
If you would either use < or >
Equality check can be used withhttps://docs.unity3d.com/ScriptReference/Mathf.Approximately.html

[wintry quarry]

force does not ever show in the inspector

don't confuse force and velocity

[languid spire]

that means don't do this
if (distanceY == 0){

[hollow forum]

thats just doing it so when the distance = 0 the force doesnt go undefined

[languid spire]

but 0.0000001 != 0

[rocky canyon]

thats the point tho.. its an inaccurate comparison

odds are it'll evaluate false when it should be true

[hollow forum]

no i mean if y = 0, then i cant run the program cause unity gives me an error

and it may just do weird stuff

i dont wanna risk it

[rich adder]

what

[hollow forum]

trust me

i couldnt run

it

cause

anything over 0 is infinity

[rich adder]

are you just making stuff up?

[hollow forum]

no mums life

trust me

im not

[wintry quarry]

distance can never be negative

[hollow forum]

it genuinely wasnt working

idk what was going on then

but it was giving me an error saying the force vector was (0.000008, infinity)

[wintry quarry]

why not just:

distanceX = Vector2.Distance(rb1.position, rb2.position);```

[rich adder]

okay well we're just giving you a heads up on how floats work. and you should never == floats

[wintry quarry]

probably because you did:

forceX = GravitationalConstant * ((rb1.mass * rb2.mass)/(distanceX*distanceX))```
And dividing by zero is bad and gives you nonsense answers

[rocky canyon]

i like Mathf.Approximately

[errant niche]

why does this say this when the horizontal axis input is set up?

[rich adder]

also a good option, i linked it above

[wintry quarry]

because you spelled it wrong

read it closely

[rocky canyon]

Horziontal

[hollow forum]

well yea thats the formula but what else can i do when they are inline in a plane

[rich adder]

Horziontal

[errant niche]

oops

[rocky canyon]

Hzntalia

[errant niche]

thanks

[wintry quarry]

Well you're discovering why micro black holes are a thing

[rocky canyon]

lol

[wintry quarry]

they shouldn't ever be able to get that close - they should have collided before that

[rocky canyon]

i made a 2D black hole once..

i would destroy the outer one if it ever got close enuff to cause problems

[timid oriole]

Guys for having a lot of grass would I do that through coding or something else

[rich adder]

shaders

[rocky canyon]

maybe then increase the original force b/c you know now its 2 blackholes

[timid oriole]

I'm getting really mixed answers online of how to go about grass

[rocky canyon]

but i doubt tahts how pyhsics works

[timid oriole]

what about shaders?

the grass have shaders on them u mean?

[rich adder]

thats one way people do grass

also not really a coding question regardless

[timid oriole]

Is there a proper channel to ask these questions

[rich adder]

#💻┃unity-talk myb

[rocky canyon]

https://assetstore.unity.com/packages/vfx/shaders/procedural-grass-gpu-shader-terrain-tessellation-tools-274414

ive used this grass asset before

works pretty good on URP

[rich adder]

zammm tass lookin lush

[timid oriole]

is it a grass mesh with the shaders on it

[hollow forum]

im sorta confused why its doing this

is the attractive force just not strong enough

[summer stump]

Grass is a suprisingly complex subject with many solutions, so it makes sense there are mixed answers
Acerola has a series on it

[timid oriole]

Yeah it's crazy some people use pngs others meshes others have shaders

[rich adder]

each has their own pros and cons

[timid oriole]

for sure yeah

guess it depends on what u wanna do

[rocky canyon]

are ur objects oriented correctly? @hollow forum

[stuck palm]

how can i catch errors coming from any source get its message and stack trace?

[rocky canyon]

w/ the X facing right.. and the Y facing upwards?

[rich adder]

oh I think @rocky canyon does this stuff @stuck palm

[timid oriole]

imo I really love valheims grass

but that's all the positive I have to say about that game lol

[dreamy dune]

when building an interaction system is it better to use raycast or the onmousehover function?

[hollow forum]

i mean i tried to rotate them around and it keeps going the same way

[rich adder]

Raycast

[rocky canyon]

can u elaborate a bit?

[dreamy dune]

Thanks

[rich adder]

OnMouseOver is very sus and unreliable also you dont have layers

[rocky canyon]

it took me ages of debugging and trial and error to get my stuff working as flawless as it does..

[stuck palm]

i know the debug build has this, but I've made this notification system and i want to basically get the console into this notification system thing

[rocky canyon]

not sure i'm able to help but i can try

[stuck palm]

so like if an error shows up the notification system will find it and display to the player

[rocky canyon]

u want ur debug messages to appear on ur notification system?

[stuck palm]

yeah

[rich adder]

my favorite is how hunt showdown does
the tall grasses can also bend and you can easily hide behind

[stuck palm]

apparently Application.logMessageReceived can do something like this

[wintry quarry]

Looks like you probably still have the default gravity enabled

[tacit estuary]

The force you are calculating is the magnitude

[hollow forum]

yes i know in each axis

then im putting that in a vector2

[hollow forum]

how do i disable it

[rich adder]

on the rigidbody

[hollow forum]

i have disabled that

[rocky canyon]

i'll have to dig thru my source and see how its printing the debugs in my console

[stuck palm]

oh that looks good, what asset is that

[rocky canyon]

1 secnod and ill find it

its free

https://assetstore.unity.com/packages/tools/gui/command-terminal-123344 @stuck palm here ya go try this out

it automatically set up for Debugs to appear in the console.. im pretty sure u can reverse engineer it

[stuck palm]

awesome, much appreciated 😄

might just use tthis tbh

[rocky canyon]

yea its pretty easy to use..

[stuck palm]

for debugging at least, will probably remove in real builds

[tacit estuary]

The magnitude will always remain positive though, it’ll always move either up or to the right

[hollow forum]

ok i made them both negative

now it just goes around a little bit

and it gets fired across the screen like a particle accelerator

[rocky canyon]

im using it for the opposite.. when i build my test builds i want a cheat type console for my testers to be able to teleport different places.. add to their inventory and whatnot..

once my testing is over then i'll remove it

(or make it a cheat thing w/o giving out the password/way to access it)

[sly pivot]

Hi, i was trying to compile a build of my game and it's giving me errors that I've never encounter before while building, i don't have any idea what to do, can someone help me? it's an android game

[rich adder]

#📱┃mobile

fix your gradle errors

[rocky canyon]

gradle gradle gradle

[sly pivot]

sorry i didn't see the channel

what is gradle? sorry im very new to this

[rich adder]

its part of the Android SDK

it builds your android app

[languid spire]

probably just need to chage the API level to 33

[stuck palm]

yeah for my game it doesnt really make much sense to keep it in, im having my friends connect to my PC via parsec to test it out but my internet can't handle more than 3 people at a time connecting 😭

[tacit estuary]

if you want the objects to orbit from gravity, the gravitational force must always point towards the planet. It would be best to calculate a vector from the satellite to the planet, and multiply the magnitude you calculated.

[hollow forum]

im hoping to use Gm1m2/r^2

[stuck palm]

@rocky canyon yeah i was correct

[rocky canyon]

heck ya

i knew it was in there

sorry i made u install it.. lol a bit busy to look for myself

[hollow forum]

it still just flies away

[tacit estuary]

That works, create a vector from the orbiting object to the planet cs Vector2 dir = planet1.transform.position - planet2.transform.position; dir = dir.normalized * Vector2.distance(forceX, forceY);
and use dir into your addForce

[tacit estuary]

for orbiting objects, the force is always pointed towards the planet

[sly pivot]

it worked, thanks everyone!

[hollow forum]

it gives an error of cannot convert float to vector 2

[wintry quarry]

what does? Show your code and the error

[tacit estuary]

oh it’s the transform.position

not sure where the float is coming from though 😅

[hollow forum]

distanceX = (Planet1.transform.position.x - Planet2.transform.position.x);
        distanceY = (Planet1.transform.position.y - Planet2.transform.position.y);

Vector2 dir = Planet1.transform.position - Planet2.transform.position;
        totalForce = new Vector2(forceX, forceY);
        Force = dir.normalized * Vector2.Distance(forceX, forceY);

        rb1.AddForce(totalForce, ForceMode2D.Force);

[tacit estuary]

Force

[wintry quarry]

And hwat line has the error?

Force = dir.normalized * Vector2.Distance(forceX, forceY); < this line?

[hollow forum]

yes that line

[wintry quarry]

I don't see how that line could possibly cause that error

show screenshots of your error and your IDE etc

[wintry quarry]

Yeah Vector2.Distance(forceX, forceY); doesn't make any sense

[sacred orbit]

The player's camera can't move up or down on this script and I have no clue why, does anyone know?

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

public class CameraMovement : MonoBehaviour
{
    public float sensX;
    public float sensY;

    public Transform orientation;
    public Transform Player;

    float xRotation;
    float yRotation;

    private void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;

        Vector3 currentRotation = transform.rotation.eulerAngles;
        xRotation = currentRotation.x;
        yRotation = currentRotation.y;
    }

    private void Update()
        float mouseX = Input.GetAxis("Mouse X") * sensX * Time.deltaTime;
        float mouseY = Input.GetAxis("Mouse Y") * sensY * Time.deltaTime;

        yRotation += mouseX;
        xRotation -= mouseY;

        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.rotation = Quaternion.Euler(xRotation, yRotation, 0);
        orientation.rotation = Quaternion.Euler(0, yRotation, 0);
    }
}

[wintry quarry]

that shuld be new Vector2(forceX, forceY)

[sacred orbit]

btw sorry for block of code between yalls convo

[tacit estuary]

it’s to get a normalized vector towards the planet and multiply by the magnitude of the gravitational force calculated

[wintry quarry]

1. you'd have to show screenshots of which object this script is attached to and what objects are assigned to orientation and Player
2. You should remove Time.deltaTime from that calculation, it is an error and will cause stuttering

[hollow forum]

it still starts flying in the opposite direction

[wintry quarry]

Vector2.Distance doesn't work with floats, that doesn't make sense

[tacit estuary]

ah

I was trying to find something similar to Math.hypot 😄

[sacred orbit]

ok so its working all of the sudden and I don't klnow why again

btw, why should you get rid of Time.deltatime there?

[rocky canyon]

planets leave orbit! lol

[sacred orbit]

is it just for camera movement stuff you dont do that?

[hollow forum]

i swear to god if its just because its far away

[wintry quarry]

because it doesn't make any sense. Mouse input is already framerate independent. Adding it here is going to make it stuttery when the framerate isn't constant

camera is irrelevant

mouse input is the reason

[rocky canyon]

im still testing stuff.. not sure this is working the way i want it to or not

[sacred orbit]

oh okay thanks

[hollow forum]

no but the problem is its flying in the opposite direction to the mother planet

[rocky canyon]

if i dont move the sun it works

[tacit estuary]

Praetor is right, instead of Vector2.Distance, you can use

dir.normalized * Mathf.sqrt(forceX*forceX + forceY*forceY);```

[wintry quarry]

or new Vector2(forceX, forceY).magnitude

[hollow forum]

still flying opposite direction

[tacit estuary]

it’s not that bad, but both will work :)

[tacit estuary]

can you show your current code?

[hollow forum]

    {
        rb1 = Planet1.GetComponent<Rigidbody2D>();
        rb2 = Planet2.GetComponent<Rigidbody2D>();
        
        distanceX = (Planet1.transform.position.x - Planet2.transform.position.x);
        distanceY = (Planet1.transform.position.y - Planet2.transform.position.y);

        if (distanceX < 0){
            distanceX = -distanceX;
        }

        if (distanceY < 0){                                                     
            distanceY = -distanceY;
        }       

        if (distanceY == 0){
            forceY = 0;
        } else {
            forceY = GravitationalConstant * ((rb1.mass * rb2.mass)/(distanceY*distanceY));
        }

        if (distanceX == 0){
            forceX = 0;
        } else {
            forceX = GravitationalConstant * ((rb1.mass * rb2.mass)/(distanceX*distanceX));
        }

        
        Vector2 dir = Planet1.transform.position - Planet2.transform.position;
        totalForce = new Vector2(forceX, forceY);
        Force = dir.normalized * Mathf.Sqrt(forceX*forceX + forceY*forceY);


        rb1.AddForce(Force, ForceMode2D.Force);
    }

}

[wintry quarry]

You are applying the force in the wrong direction

p1 - p2 is the direction FROM p2 TO p1

so that would be the direction of force to apply to P2

you are applying it to P1

aka - backwards

[hollow forum]

do i flip it

planet2 - planet1

[wintry quarry]

yes

but you need to apply forces to both planets, right?

[hollow forum]

i just want one to orbit the other

[spare mountain]

huh that's a really intuitive way to think about it

[hollow forum]

its still flying in the opposite direction wtaf

it now flew in the opposite direction towards the planet but it didnt curl around

probably means the force isnt strong enough

[rocky canyon]

in my version u have to add an initial force to get teh orbit to start

or else the planet just gets sucked into the sun

[tacit estuary]

if it’s flying towards the planet, that means it’s working. You need some initial force

[hollow forum]

i just did that by putting an add force in the start function

[spare mountain]

I mean you could massively simplify this code just by doing something like
velocity = (otherPos - myPos) * G * (m1 * m2) / Mathf.Pow(Vector3.Distance(tempPos, otherPos), 2)

[rocky canyon]

public class Orbit : MonoBehaviour
{
    public Rigidbody2D sun;
    public Rigidbody2D planet;
    public float gravitationalConstant = 1f;

    void Start()
    {
        Vector2 distanceVector = planet.position - sun.position;
        float distance = distanceVector.magnitude;
        float orbitalSpeed = Mathf.Sqrt(gravitationalConstant * sun.mass / distance);
        Vector2 tangent = new Vector2(-distanceVector.y, distanceVector.x).normalized;
        planet.velocity = tangent * orbitalSpeed;
    }

    void FixedUpdate()
    {
        Vector2 distanceVector = sun.position - planet.position;
        float distance = distanceVector.magnitude;

        if (distance == 0f) return;

        float forceMagnitude = gravitationalConstant * (sun.mass * planet.mass) / (distance * distance);
        Vector2 force = forceMagnitude * distanceVector.normalized;
        planet.AddForce(force);
    }
}
``` heres my version if it helps

its really old.. soo not sure its perfect by any means

oh i did the same thing distance == 0f

lmao.. oops

[hollow forum]

now its just flown off the screen

rb1.AddForce(impulse, ForceMode2D.Impulse);

impulse has a value of 1.0

10,0

and is in the start function

[rocky canyon]

gotta find a value that works for the gravity

it has to be exact

thats y i use math to figure out the needed velocity depending on the gravitationalConstant

if u crank that up.. u also have to crank up the initial vel

[wintry quarry]

why would you apply a constant force?

[hollow forum]

no

[wintry quarry]

also why impulse mode

[hollow forum]

this is just an impulse in the start to get it going

[wintry quarry]

ok well you can't just guess at that number

[rocky canyon]

[wintry quarry]

it's going to need to be the exact orbital velocity for that altitude

[rocky canyon]

i mean you could guess it

[wintry quarry]

or the orbit isn't going to be stable at that altitude

[rocky canyon]

but good luck

[hollow forum]

can you teach me the math

[summer stump]

Simulating orbital mechanics requires knowing orbital mechanics

[wintry quarry]

https://byjus.com/orbital-velocity-formula/

[summer stump]

There are lots of sources out there

[hollow forum]

400 hours of kerbal space program is not helping here

[rocky canyon]

or copying from someone that already knows it

[wintry quarry]

to be honest, it really should lol

that's where I learned almost all my orbital mechanics

[hollow forum]

yea same

but idk all of the formulas and stuff

like im guessing im tryna find the speed at apoapsis no?

[wintry quarry]

but you should know intuitively that for a given planetary mass and a given altitude, there is exactly one orbital velocity

[wintry quarry]

Do you want a circular orbit

or an elliptical one

[hollow forum]

as long as it orbits its no issue

elliptical would be cooler

[wintry quarry]

technically they're all elliptical

[rocky canyon]

not sure how to make elliptical orbits.. lol i just move the sun a bit after the game starts

and i lost a planet

[scarlet shuttle]

should camera control go in update or fixed update?

[rocky canyon]

lateupdate

[rich adder]

Update

[rocky canyon]

or update. u want smooth camera

[rich adder]

isnt LateUpdate better for follow?

[rocky canyon]

that what ive heard

[rich adder]

in terms of rotating I usually do update tho, not sure if thats 100%

ofc anything else i use Cinemachine 😄

[rocky canyon]

i use cinemachine even if i have custom camera's

i just put my camera code on an empty.. w/ a vcam tucked inside

[rich adder]

oh yeah i def used Cinemachine just as camera with Body set to none

[rocky canyon]

automatic transitions got me hooked

[rich adder]

butter smooth

[hollow forum]

i mean i calculated it to 4.767x10^-5

[rich adder]

the only annoyance is controlling them with code 😅
like some cameras you wnt the transition time to be more than 0 and sometimes you want 0

[rocky canyon]

u can jack my code if u want

[rocky canyon]

u can intercept the brain.. and change the transition variables before changing cams

but i assume thats the annoyance ur talkin about

ofc u can set preset stuff too

[rich adder]

yeah pretty much

[rich adder]

like going from an FPS camera with 70FOV to 40ish FOV just for "zoom in" effect, blending is acceptable.. But If I want my player to look at a CCTV camera, the transition is ridiculously not needed to from from Player to a CCTV cam

[rocky canyon]

oh yea... i need to do that mechanic soon

that shuld be much snappier

u dont need the out of body tansition i agree

[unreal adder]

i have 93 line script can somebody read and explain my glitch?

Hallofax

[unreal adder]

like i making a prototype to like replicate the mechanics of a other game and in that it uses right click to dribblewhich applies less force to the sphere(the ball) and shoot with more force i made it so however long you hold it down it multiplies the force of the shot but whenver i play test it dosent reset the power which it is supposed to do if i click very very fast

[polar acorn]

Such as x / 0 or ln(-1)

[wintry quarry]

it's what you get when you divide by zero or perform other mathematical sins

[rocky canyon]

lol ^ well explained

ty lol apple stage manager

[rich adder]

you got off the important part again
click blendtree Show me the Clips in the blend tree and which values are picked in inspector

[hollow forum]

why are you finding a tangent?

[rocky canyon]

In orbital mechanics, finding the tangential velocity (often referred to as initial impulse in your case) is crucial because it determines the initial speed and direction perpendicular to the line connecting the two bodies (e.g., planet and sun). This velocity ensures that the orbiting body (planet) moves in a circular or elliptical path around the central body (sun or another planet).

[hoary light]

sooo like
if i press anywhere
it spawns the item on like a line so if i press under that line for example it spawn the fruit on that axis line
