Ok

That still didn't work

[stoic moon]

I have an upgrade in a scene that I don't want to be re-instantiation when i leave the scene and come back.I have a boolean that controls weather or not it's been picked up. I have multiple of these objects in my game, so using something like static wont work since it effects all of the types of that object. How would i go about solving my problem?

[craggy kite]

can you show your updated script?

[olive mesa]

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

public class PortalController : MonoBehaviour
{

    public Transform otherPortal;
    public Vector3 playerWarpOffset;

    void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Player"))
        {
            Rigidbody2D playerBody = collision.GetComponent<Rigidbody2D>();

            if (playerBody != null)
            {
                Vector2 velocity = playerBody.velocity;

                playerBody.transform.position = otherPortal.position + playerWarpOffset;
                playerBody.velocity = velocity;
            }
        }
    }
}

wait

I'm still using transform.position

[craggy kite]

which is okay

[olive mesa]

Well that made no difference

[craggy kite]

Did you debug.log your velocity before and after the transform.position?

[olive mesa]

no

It says the same value each time I print it

But it doesn't usually stay the same

[still tendon]

I am trying to calculate a square's top right and bottom left positions given the top left and bottom right positions.

//pos1 is topleft, pos3 is bottom right
public GameObject CalculateSquareTopRight(GameObject pos1, GameObject pos3)
    {
        return gameGrid[int(pos1.transform.position.x), int(pos3.transform.position.y)];
    }```
This is what I have so far for the top right position. gameGrid is a int[,] from a grid generated in a different script. For some reason, I'm getting an "invalid expression of int" error and I'm not sure why. The end goal here is to outline corners by getting the game object, getting the sprite renderer, then changing the material to an outline material for player indication

[olive mesa]

So, every time the velocity resets after the teleport it says 0

[craggy kite]

and before it has the right velocity?

[olive mesa]

sort of

[still tendon]

the grid is made out of generated game objects, with added components of spriterenderer, 2d box collider, and a spritemaster script

making tiles basically

[olive mesa]

so...

Every time it resets the velocity, it says 0.0 every time I print it

But when it doesn't reset velocity (which is pretty rare) is prints the actual velocity

[craggy kite]

"Resets the velocity" happens where? Bit confused here

[olive mesa]

I'm making portals

And most of the time when I enter the trigger of the other portal, my velocity gets set back to 0 when I teleport

And before for some reason

[craggy kite]

hm okay, but the teleport only happens in those lines you showed us, right?

[olive mesa]

yup

[craggy kite]

so if you run full speed in the collider, it sometimes willr eturn 0?

[olive mesa]

It seems to be somewhat dependent on the velocity when entering the trigger

[craggy kite]

yeah, sometimes you just stop at your teleport door, I guess? close to zero?

[olive mesa]

I'm dropping down into it

You can see sometimes it prints the actual velocity, and sometimes not

As if I collided with the portal before it was triggered

But that wouldn't make sense because the only collider on the portal is set to trigger

[craggy kite]

Could you try to save the velocity, then set it to zero, teleport the player and then reassign it?

[olive mesa]

Actually, I think I just figured it out

But it sounds stupid so idk

[craggy kite]

Tell 🙂

[olive mesa]

So, I think what happened was at certain velocities, I was colliding with the floor before the trigger somehow

I made the trigger taller and it doesn't happen anymore...

But what I don't understand is how I could have hit the floor first

[craggy kite]

https://docs.unity3d.com/Manual/ExecutionOrder.html

your physics get calculated before OnTrigger Events, thats why you might hit the floor already and then the trigger teleport happens.

[olive mesa]

Oh

Well thanks for your help 🙂

[craggy kite]

you are welcome 🙂 just have as big colliders as possible and rather delay instead of using small colliders 🙂

[limpid drift]

so nobody?

[toxic mauve]

hi, I dont really know where to put this, but is there a way to create a pop up emote for characters during events or interactions between the MC and NPCs?

[toxic mauve]

BlackthornProd or Brackeys has some good tutorials

[craggy kite]

if you have some code, you should show it to us

[craggy kite]

Phew, some kind of general question. You can have a worldcanvas between the characters and animate images there.

[toxic mauve]

Thank you! I'll check that out!

[limpid drift]

[SerializeField]
    GameObject bullet;

    float fireRate;
    float nextFire;

    // Use this for initialization
    void Start () {
        fireRate = 1f;
        nextFire = Time.time;
    }
    
    // Update is called once per frame
    void Update () {
        CheckIfTimeToFire ();
    }

    void CheckIfTimeToFire()
    {
        if (Time.time > nextFire) {
            Instantiate (bullet, transform.position, Quaternion.identity);
            nextFire = Time.time + fireRate;
        }
        

this is what i guide had

[craggy kite]

and its not working?

[limpid drift]

nope

what i want is if the player triggers the enemy hitbox it start shooting

does not even have to follow the player or anything

[craggy kite]

then you should look into OnCollisionEnter or OnCollisionEnter2D or OnTriggerEnter or OnTriggerEnter2D to have some boolean to set to true and check for in update

[limpid drift]

so right now this is my trigger on the enemy controller

 private void OnTriggerStay2D(Collider2D Player)
    {
        if (Player.gameObject.CompareTag("Player"))
            
       
        animator.SetBool("attacking", true);
        
    }

now what i want to add is that it fires a bullet/spell when this trigger happends

[craggy kite]

you could use https://docs.unity3d.com/ScriptReference/Animator.GetBool.html in your Update to check against and then run your fire script

[limpid drift]

thing is idk if that fire scripts works because it seems wrong

because when my player hits the enemy trigger now the game just lags to 1fps

[craggy kite]

hm, did you debug.log to check if it keeps instantiating all the time

[limpid drift]

kinda rage deleted that whole script haha

[wooden ruin]

trying to make a randomly generated rougelike, would it be more effective to use tilemaps or sprites for the rooms?

[compact knoll]

that really depends how you want to structure things really. That's a design decision only you can make. However I personally think tilemaps are better 🤷‍♂️

[wooden ruin]

Thats what i was going to do originally, but i couldn't figure out how to move them around

and then the tutorial i was watching for it just used sprites

[compact knoll]

tell me it wasn't the blackthornprod one where he makes like 16 different sprites for something a single tilemap prefab could do

[wooden ruin]

🤔

oh can you put tilemaps into prefabs? that would make it easier

didnt think of that for some reason

[compact knoll]

yup, anything can be a prefab if you believe hard enough

you doing something like isaac style generation where you generate the layout of a dungeon given a set of specific rooms or more open where 100% of the map is randomly generated

[wooden ruin]

yep

oh wait

i didnt read that right

1st one

i think i can get it now that i know you can use prefabs

[compact knoll]

yeah i'm doing the same thing in a project i've been working on. you can set it up so it uses just a single base room tilemap for each room, remove/add relevant entry ways at runtime, then apply an inner layout. this way is infinitely more scalable than using sprites with holes where the entry ways should be

[wooden ruin]

For some reason it just makes 1 block when i load it, looks like they don't keep their offset or something

[compact knoll]

not 100% sure what you mean, could you elaborate or provide an example?

[wooden ruin]

when I try to instantiate a new one of the prefab, it just spawns one tile instead of the room

[nova bear]

oh great

i can ask questions here instead of being at beginner/general coding channels

[wooden ruin]

and the prefab has the room when i open it

[nova bear]

more 2d people

[wooden ruin]

sure

[compact knoll]

did you save just the tilemap layer as a prefab or did you save the grid with the layers attached as a prefab?

[wooden ruin]

ok, im not very experienced with this and havent even noticed there was a grid since i made the first tilemap in this scene a few weeks ago

[compact knoll]

no worries, everyone has to start somewhere lmao. But yeah i think you have to save the grid for it to work properly. Plus that way you can have multiple layers for your prefab

for example, this is how i've got my room prefabs set up. The parent gameobject contains the grid and the room controller script. floor and walls are separate layers, the removable walls contains separate layers for sections that can be removed at runtime when necessary

[wooden ruin]

nice, i got it to spawn the room

[compact knoll]

awesome!

[limpid drift]

@compact knoll could i maybe ask you a question aswell

private void FireBullet()
    {
        Instantiate(Spell, transform.position, transform.rotation);
    }
    private IEnumerator AutoFire()
    {
        while (true)
        {
            FireBullet();
            yield return new WaitForSeconds(FireRate);
        }
    }

this is what i got in my enemy controller script

this is what i want it to be

private void OnTriggerStay2D(Collider2D Player)
    {
        if (Player.gameObject.CompareTag("Player"))
            //make autofire true so it keeps on doing this if the player triggers the hitbox
            animator.SetBool("attacking", true);
        
    }

if anyone knows how i can do this would help me out a lot thanks

[compact knoll]

your loop in your coroutine will never stop with the way you have it set up. you could also potentially remove the loop entirely, and set your coroutine to check if it can fire, then fire, then wait for the cooldown, then enable firing again. and when it can't fire, just return or whatever.

[limpid drift]

but the way it is now

it only fires once when i press play that part confusses me

should it not keep firing?

and how would i setup the check so it only does the firebullet when the player is in the enemytrigger?

[compact knoll]

where are you starting the coroutine? because it isn't in your OnTriggerStay function

[limpid drift]

void start

[compact knoll]

that's why. you are only ever calling it in start so it will only run once at start

[limpid drift]

so putting it inside the triggerstay should do the trick?

[compact knoll]

well sort of. You do still have to make the other changes i suggested or it won't work the way you expect it to

[limpid drift]

https://gyazo.com/6a89da399251cf16f0ac843f23beeca7

like this?

put the coroutine inside the ontriggerstay and this happends

laggs the fuck out of it and 0 spells

fired

[compact knoll]

show me the code

[limpid drift]

 void Start()
    {
        
        animator = GetComponent<Animator>();
        rb2d = GetComponent<Rigidbody2D>();
        spriteRenderer = GetComponent<SpriteRenderer>();
    }

    void Update()
    {
       
        if (health > 0)
        {
            if (this.transform.position.x > Player.transform.position.x)
            {
                isFacingLeft = true;
            }
            else isFacingLeft = false;

            Box.transform.position = enemyCollider.bounds.center + (isFacingLeft ? Vector3.left : Vector3.right) * 1f;
            spriteRenderer.flipX = isFacingLeft;
            float distancetoPlayer = Vector2.Distance(transform.position, Player.position);

            if (distancetoPlayer < Attackdistance)
            {
                AttackPlayer();
                animator.SetBool("Run", true);
            }
            else
            {
                Stopattackplayer();
                animator.SetBool("Run", false);
            }
        }
    }

    private void OnTriggerStay2D(Collider2D Player)
    {
        if (Player.gameObject.CompareTag("Player"))
            StartCoroutine(AutoFire());
            animator.SetBool("attacking", true);
        
    }

    private void OnTriggerExit2D(Collider2D box)
    {
        animator.SetBool("attacking", false);
    }


    private void FireBullet()
    {
        Instantiate(Spell, transform.position, transform.rotation);
    }
    private IEnumerator AutoFire()
    {
        while (true)
        {
            FireBullet();
            yield return new WaitForSeconds(FireRate);
        }
    }

[snow willow]

You're starting a new coroutine every physics frame

[limpid drift]

ah that can explain it

so how should i fix this?

[snow willow]

Maybe use OnTriggerEnter2D?

[compact knoll]

something like this:

    private void OnTriggerStay2D(Collider2D collision)
    {
        if (collision.CompareTag("Player"))
        {
            if(canFire)
                StartCoroutine(AutoFire());
        }
    }

    private IEnumerator AutoFire()
    {
        
            canFire = false;
            Instantiate(Spell, transform.position, transform.rotation);
            yield return new WaitForSeconds(FireDelay);
            canFire = true;
    }

[snow willow]

eh... that's kinda sketch too but I guess slightly better

it at least won't blow things up

[limpid drift]

but if i do it inside the ontriggerenter2d it will do it only once when inside the trigger zone

[snow willow]

YOu have a while (true) though

it will start the coroutine once, but the coroutine will continue shooting forever

[limpid drift]

but the animator will only do the animation once aswell then

even if the coroutine will keep going

[snow willow]

maybe do the animation in the coroutine then?

or rather

wait why would it only do the animation once

[compact knoll]

set the animation to loop?

[snow willow]

^

you're setting the bool in OnTriggerEnter

it should keep playing till you set it false, no?

TBF it depends on how you set up your state machine in the animator

[nova bear]

how can I make a child gameobject unaffected by the parent's changing position?

[limpid drift]

u were right praetor

but now i got a other thing i got it set to ontriggerenter2d

but it wont do the Instantiate(Spell, transform.position, transform.rotation);

it destroys the gameobject the second i enter the trigger zone

[snow willow]

you can't really. DOn't make them parent/child if you want that

[nova bear]

ok

[limpid drift]

your right its working now

now i need to set a boxcollider on the bullet make it deal damage and give it velocity because now it just standing still

thanks alot im happy its atleast working now when the player enters the trigger

[misty kelp]

Excuse me, I can't make scripts for the cooking game, because I don't know how, because I need help.

Please respond to me.

[compact knoll]

All this effort asking so much could have been spent learning c# and you would have the skills to do so by now

[vocal condor]

No ones responding because you need to go watch a tutorial.

[misty kelp]

Of what?

[vocal condor]

Of whatever you need help with.

[misty kelp]

I'm just working on a game.

[compact knoll]

Yep and you've been asking for your cooking mama type scripts for weeks on here and on reddit. Just go learn c# and you'll be able to do it yourself

[vocal condor]

Or go on the forums and look for someone to team up with you; to do the scripting for you.

[misty kelp]

I can't go on the forums.

[misty kelp]

I just need help.

[vocal condor]

With what? What part of the scripting?

[misty kelp]

With just the cooking steps.

[vocal condor]

What's the cooking steps.

I have a question about Java scripting but I'm too lazy to actually formalize it in words unless there's someone on the channel who might be able to answer it
https://dontasktoask.com/
Be thorough in your questions.

[misty kelp]

Steps like from cooking mama.

[vocal condor]

What have you gotten already?

[misty kelp]

Nothing.

[vocal condor]

Good luck.

[misty kelp]

I just need steps for a cooking game.

[midnight nexus]

hey i got a question, can someone explain to me how to go about 2d platformer controlers and what i need to do physics wise?

[vocal condor]

There are lots of 2d platformer tutorials out on the web. Google/YouTube one/some of your liking and pick what works for you.

[misty kelp]

Here's the game I'm working on.

[midnight nexus]

i know, but can someone explain it to me here? as i already looked up a lot of tutorials, but none of them were really what i was looking for

[misty kelp]

I need steps like sautéing the cabbage, slicing the green onion, folding the gyoza, and deep frying the gyoza.

[compact knoll]

Look up some recipes?

[misty kelp]

Making a similar game to Cooking Mama.

[vocal condor]

If you know your exact particular question folks might be able to answer your question else folks will likely not hold your hand through the entire process; especially one that there's been many tutorials about. As is, your question about how to go about a 2d platformer and implementing physics is way beyond the scope of Discord Q/A.

[midnight nexus]

alright forget it

[misty kelp]

Hello?

[hollow crown]

What has this got to do with 2D code or Unity

[misty kelp]

This is simple, those are the steps for the first recipe in the cooking game.

[hollow crown]

If you're looking for code, I think you've been told before that nobody will be giving that to you

[misty kelp]

That's a lie.

[hollow crown]

if you're looking for advice, the question's extremely general, and I would just go through some basic tutorials to build up general knowledge

[abstract olive]

I just don't understand. You post once a week, asking for someone to make the game for you, and then disappear when nobody (obviously) does. What are you doing between each time you spam this question? You could have been learning, that's for sure.

Stop asking, this is your last warning.

Also, just want to point out that including the above link, you've been told another two times to stop asking for free work.

So, we're just going to skip the warning/mutes if you do it again and go straight banning.

I suggest you do some learning, make an attempt, and then ask for help if you have specific coding questions.

[fading osprey]

im trying to instantiate an object in a 2d game using z axis, this is the code i have

Vector3 pos = Ground.CellToWorld(new Vector3Int(i, o, 0));
Instantiate(Prefabs[0], new Vector3(pos.x, pos.y, -2), Quaternion.identity);
```but it seems to be instantiating the object but doing nothing along the z axis, Ground is a tilemap and Prefabs[] explains itself with its name, the prefab has no scripts on it, what am i doing wrong

[compact knoll]

may i ask why you need it to be at -2 on the z axis if this is 2d?

[fading osprey]

some layering stuff (yes i know about sorting order but i alreadyam using some sorting order stuff to make things not weirdly overlap)

andm ultiple of the object are being created with the possibility of them being close, i set it to -2 for testing

once it acutally does stuff on the z axis i will set it to the value to get the diffrent things to layer correctly

[compact knoll]

and you are certain that the object you instantiated is not on position -2 along the z axis?

[fading osprey]

yes

im checking the editor

[compact knoll]

what is its position on the z axis?

[fading osprey]

wait hold on, for some reason some of the instantiated things are doing z axis stuff, ima check the other pieces of the code that spawns them

ok i found the problem sorry for wasting some time

[minor barn]

How do I set the connected rigid body for a spring joint using a script? It only has a get function.

Ah, found it, it's connectedBody, not connectedRigidBody.

[dusky wagon]

I have a moving platform. I used to move that platform with the Vector2.MoveTowards function and applied friction to the object, by setting the player to be a child object of the platform whenever he touches it, but now I switched to moving it with rigidbody velocity and the friction method doesnt work anymore. The player just falls right off. Why is that and how could I fix it?

[magic shoal]

i get "no overload for method 'addforce' takes 3 arguments",anybody knows what is wrong with my code?

[hollow crown]

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

public void AddForce(Vector2 force, ForceMode2D mode = ForceMode2D.Force);

Also, 0 times anything is 0, so your logic also has flaws

[magic shoal]

wait lemme try something

[magic shoal]

got this error "Movement.AddForce(Vector2, ForceMode2D)' must declare a body because it is not marked abstract, extern, or partial"

[hollow crown]

what did you do?

[magic shoal]

wait

this

i also tried putting {} instead of a ; and got 2 errors

[hollow crown]

You just copied the signature of the method you're trying to invoke that I posted, that's not going to do anything

invoke the method using variables that match the signature's definition

[stoic moon]

I have an upgrade in a scene that I don't want to be re-instantiation when i leave the scene and come back.I have a boolean that controls weather or not it's been picked up. I have multiple of these objects in my game, so using something like static wont work since it effects all of the types of that object. How would i go about solving my problem?

[stoic moon]

nvm i found a fix

[dusky wagon]

Why does this happen? I would assume that velocity also moves a child object, because my player character also moves with velocity and all its child objects move with it and the velocity also changes the transform

[dusky wagon]

I looked some things up and from what I can tell, it should work. is it the way I am moving the platform? Im moving it like this:

rb.velocity = (pos[movingTowards].position - transform.position).normalized * MovementSpeed;

Both of the points are Vector2s

[stoic moon]

How would i make something launch towards the player using addforce?

[dusky wagon]

@stoic moon probably the exact same system I used here

Just change pos[movingTowards].position to be your target position and transform.position to be the position of your object

[stoic moon]

thanks

[vocal condor]

var direction = (target.position - transform.position).normalized;
var force = direction * speed;
rb.AddForce(force);

[dusky wagon]

You could also do that in a single line I think

[vocal condor]

I was being informative using code relative to naming conventions.

[dusky wagon]

Yes

[stoic moon]

that kinda just moves the enemy towards the player, how would i make it be flung towards it?

[vocal condor]

Play around with speed 🤷‍♂️

[dusky wagon]

And only call it whenever you want to launch it, not every frame

[stoic moon]

I have this script to handle my doublejumping(In a bigger jumping script). My problem is that the jump instantly adds 2 to the jumpamount and stops you from doublejumping if i use getkey, however using getkeydown makes the jump really unresponsive. how can I fix this?

[vocal condor]

Try using GetKeyDown rather than GetKey.

[stoic moon]

Using getkeydown makes it so that the space bar sometimes doesnt register

or that you have to wait a bit before placing space

i mean pressign sorry

AHHH IC ANT SPELL

[vocal condor]

It should always register if done correctly

You'd want input to be handled in Update and physics to be done in Fixed Update

[dusky wagon]

Yes GetKeyDown checks if the key was pressed in the current frame, but if you run it in fixed update, the update might not run the frame you press it

[stoic moon]

It should be running in regular update

[vocal condor]

If anything you could place everything (your if statement and all) in Update since you're only going for instantaneous jumps.

[stoic moon]

Here's my full jumping code, running in update

I have the same problem with regular jump and using getkey fixed the problem

oh wait its running in fixedupdate

wow

I'm really dumb

[nova bear]

I tried adding text to a GameObject but it doesn't show at all

oh wait

do I need a canvas?

[dusky wagon]

Also I assume no one knows why this happens? If so I would try moving the objects with vector2.movetowards, but that would make detections a lot harder

[vocal condor]

Are you moving the player with velocity? If so you're overriding all friction and opposing forces.

[dusky wagon]

Oh yeah that might be the case

[nova bear]

I added text to my gameobject but it's really blurry

how can I fix this?

[vocal condor]

Try using tmpro

[dusky wagon]

Thank you! That seems to be the problem. Now I only need to find a way to fix it

[dusky wagon]

@vocal condor do you have an idea about how I could fix this? I tried adding the velocity of the moving platform to the player, but I calculate the movement in the fixed update and not every frame so that when I do this, the player always has a higher velocity than the platform because of the short moments between the fixed updates

[vocal condor]

Perhaps apply player movement in fixed update as well; only acquiring input/character states and such from update.

[dusky wagon]

The player movement already is in the fixed update

Im going to try to put the platform movement in fixed update, but I dont think that will do anything, since Im working with velocity

[vocal condor]

Well, you're eventually going to have to use cumulative velocity by either having extra velocity variables to be added to your formula or using forces (introducing sliding, if not overwriting).

rb.velocity = (...).normalized * MovementSpeed + extraVelocity;
```ie movement velocity + extra velocity.

[dusky wagon]

Hm the problem would be the y velocity. Its a sidescroller game so the player has gravity and jumping phyisics, and there isnt a set value on how fast he is

[dusky wagon]

Is there a way I can modify this in order to work with this gravity?

[vocal condor]

It should have simply been your original formula with the inclusion of extra velocity.

How were you implementing jump prior to this?

[dusky wagon]

It was like this:
Check if the jump key was pressed in the update method. If it is, check if the player is on the ground. If so jump. This jump works with add force. If not, check if a double jump is available (boolean) if so, activate the double jump. This one works by setting the y velocity to a certain value

Also I dont necessarily need the object to move with rigidbody velocity, but I have a script on the player that detects when the player is between two objects and one of them is moving towards him and kill him if it is and I need a way of detecting whether the object is moving towards him or not and thought the best way for the would be rigidbody velocity since it would be universal for all objects

However if it is easier to just do it with Vector2.MoveTowards, I could do that as well

[vocal condor]

Try out a variety of ways and pick your poison. Implementing fake physics with rigid body physics has always been extra work. Hopefully you can find a middle ground that will satisfy both needs.

[dusky wagon]

Okay I guess Im going to go with the second way and make some sort of script that holds a direction variable. Anyway, thanks for all of the help!

[still tendon]

Does anyone know what's up with this image file? I'm just trying to get it in a proper format

[kindred pebble]

what are you currently using for regular movement?

[still tendon]

I’ve been trying to edit the 2d platformer template by using my png in place of the character idle animation and it doesn’t show up in the game play, it shows the pre-existent walk animation but when the character goes idle it’s invisible. I’m not sure why. (Didn’t mean to interrupt)

[kindred pebble]

ah okay, transform movement. I would do something simple like track your current movement when you're pressing a / d then when you get the input for dash you just move in that direction with transform.position for an extended amount of time either with a coroutine or update timer. So move in x direction with y speed for z amount of time

you would track your movement a/d so you can 'dash' in that direction

will also have to 'turn off' regular movement during dash

    {
        yield return new WaitForSeconds(dashCoolDownTime);
        canDash = true;
    }

``` would be an example of a Coroutine 

then when you want to call that you would do 
```            StartCoroutine(DashCoolDown());

[still tendon]

Ferb

[kindred pebble]

it's basically calling that timer from below

kind of, you would need to set up different bools to check if dashMovement is done, if you can move, etc.

yeah so with that you're just setting a new transform, you'll need to do it with Time.deltatime

I have a simplyish setup I can send you from an old project if you want more code

[mellow sleet]

hi i have a animation in my prefab, can someone tell me what the code should look like that tha animation gets played?

[cedar panther]

I have a pretty basic question, I know I can get the angle between 2 points using Vector2.Angle, but how would I get a Vector 2 from a given angle and distance?

[late viper]

you don't. the math doesn't work that way

[cedar panther]

sorry, given angle, distance AND position

[tall current]

that is a Vector2 though...

[late viper]

he wants to find the other point

[cedar panther]

that's... true

[tall current]

reverse-trigonometry it?

[cedar panther]

maybe a use case would make more sense, I'm trying to raycast to the left and right of my gameobject

and other positions as well...

[late viper]

why not just use Physics2D.Raycast then?

[cedar panther]

Physics2d.Raycast requires 2 points

I don't have the second point

[tall current]

it does?

[late viper]

it requires a point and a direction

[cedar panther]

I didn't see an overload for angle

[tall current]

it requires an origin and a direction.

[late viper]

not two points

[cedar panther]

oh it literally says direction in the method

[tall current]

yeah.

[cedar panther]

So that means the angle is also a Vector2

[tall current]

the angle?

[late viper]

uhhh no?

[cedar panther]

ahh.. right.. angle is different than direction

[tall current]

mhm

same angle can have different directions

[late viper]

just use transform.right

[tall current]

what are you trying to do?

[cedar panther]

A sweeping raycast from the left and the right object to forward

[tall current]

I feel like you don't want to use raycasts for that...

[cedar panther]

no? I'm doing a collision and distance check over time

[tall current]

Do you want info on the surrounding area?

why'd you need sweeping raycasts?

[late viper]

if you want to check an area you can use circlecast or boxcast

[cedar panther]

nah I need to check specific points.. it's kind of an odd game

[tall current]

you can still find specific points I believe

this maybe?
https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCircle.html

[cedar panther]

so I need to know if it hit, what it hit, what angle it hit it at, and what it is.

[tall current]

this should give you all that info.

[cedar panther]

it has to be more granular

[tall current]

with some mixing in of raycasts maybe...

hmm, okay.

If ya say so. You should probably make a method that cast rays in all directions with a specific distance between each ray from the origin all around you then?

[late viper]

you should explain what you want to do in more detail, because right now its unclear what you actually need

[cedar panther]

ok so I'm emulating something similar to lidar/sonar

the data return is going to modify the audio, volume and pitch, along with some audio effect based on what you hit.

so as the raycast sweeps on the left and right to forward over time, you will get audio feedback on the environment

[tall current]

maybe you can try using this:

    private void GrainCast(float rayAmount)
    {
        //Creating apropriate shooting angles and angle intervals for the entire thingie.
        float angleStep = 360 / rayAmount;
        float angle = transform.rotation.eulerAngles.z;

        for (int i = 0; i < rayAmount; i++)
        {
            //Ray direction relative to the angle.
            Vector2 localDir = new Vector2(Mathf.Sin(angle * Mathf.PI / 180f), Mathf.Cos(angle * Mathf.PI / 180));

            Physics2D.Raycast(transform.position, localDir);

            //Adds the next angle interval.
            angle += angleStep;
        }
    }

should give you a surrounding raycast

[cedar panther]

that's far more complicated than I expected it to be

[fading osprey]

how do i make an entire sprite a solid color?

[cedar panther]

I'll take a look at that, thanks @tall current

[tall current]

it the sprite already is a certain colour, you cannot.

You can work around that by using SpriteMasks and other shenanigans.

[fading osprey]

ok

[tall current]

You might have to modify it a bit. I wrote that just now - so I haven't tested it.

[late viper]

its also not very efficient

[tall current]

I wouldn't recommend spamming raycasts everywhere either.

But it should be fine if it's only the player doing it.

The top answer here recommends using Physics.OverlapCircle as I said earlier.
https://answers.unity.com/questions/30224/how-expensive-is-ray-casting.html

[cedar panther]

Yeah there is only one object using the raycasts

[tall current]

it's not optimal - but it should be fine even if you're casting like 360 rays... probably.

[cedar panther]

They are going to be cast over time, so it's going to be a handful of raycasts per second

[still tendon]

public GameObject CalculateSquareTopRight(GameObject pos1, GameObject pos3)
    {
        GameObject pos2 = GD.tileGrid[Mathf.FloorToInt(pos1.transform.position.x), Mathf.FloorToInt(pos3.transform.position.y)];
        return pos2;
    }```

So I got this GameObject that returns the top right position of a square based on the top left and bottom right positions, given through player input. I am getting an ``index out of bounds array `` error for GameObject pos2. I don't really understand why, tileGrid is a GameObject 2d array that generates tile gameobjects in a grid. Could anyone help me out here?

[snow willow]

if your grid is 2x2, and the object is at position 2, then you're trying to access index 2 of the array

which is out of bounds

0 and 1 would be the valid indices into an array of length 2

so maybe you want position.x - 1?

[still tendon]

should I do - 1 at the end of each?

yeah

I'll try that. I know pos1 and pos3 are fine because when I press numpad 1 the tile changes on those corners

It seems like that works, thanks @snow willow

@snow willow Okayyy, for some reason the problem is still persisting

    public GameObject CalculateSquareTopRight(GameObject pos1, GameObject pos3)
    {
        GameObject pos2 = GD.tileGrid[
Mathf.FloorToInt(pos1.transform.position.x) - 1, 
Mathf.FloorToInt(pos3.transform.position.y) - 1];
        return pos2;
    }```

}```

this is my movement scrip code

and the player cant jump

[opal socket]

I guess it’s because the name of the key is “Jump”, iirc? Not sure, i’m always using KeyCodes anyways

Also it’s in FixedUpdate so your input might not be detected at the moment you press the spacebar

[midnight nexus]

Oh okay, well, I don’t think that was the problem cause I changed it and It still didn’t work

Thanks anyways:D

[craggy kite]

isGrounded ever true?

@midnight nexus

[compact knoll]

is your layermask correct? you can print your layermask to the console to ensure it's correct. Or instead of setting it the way you are, you could serialize a LayerMask field and set it in the inspector that way

[midnight nexus]

Oh okay, let’s try that!! Tysm

Omgggg

It worked

Thanks!!!

[compact knoll]

sweet, glad that worked for you

although, you may want to consider switching to a boxcast or circle cast since the linecast will only check between two points and i'm sure your player is significantly wider than a single line

[midnight nexus]

yeah

i should probably do that

thanks for all the help :D

[gusty ermine]

How do I make an image that I can drag and drop with the mouse?

What sort of code would I n eed for that?

IMAGE

NOT sprite

[still tendon]

an image that u put into the game is sprite

so it is technically sprite

and u can google that yk?

[turbid heart]

No. Image is UI. Sprite is sprite renderer

[gusty ermine]

^^ I can't figure out how to make sprites actually show up on my canvas so I'm using an image UI element, and I need to know how to drag and drop that image UI element

[gusty ermine]

And google and youtube aren't helping in the slightest

[still tendon]

ic

I haven't messed with the UI system enough to know about that

https://youtu.be/c47QYgsJrWc

is this what you're looking for/

[gusty ermine]

That uses unity 4 which is totally unhelpful because of how out of date it is

[still tendon]

try it out it might still work

[gusty ermine]

I tried it about an hour ago and it didn't work

I tried about 10 other youtube tutorials too and they didn't work either

Which is why I'm here

[still tendon]

https://tenor.com/view/face-palm-shake-my-head-smdh-smh-muppets-gif-5928154

i can't help you mate

[still tendon]

u should try some kind of code that works with a sprite but instead of messing with the transform of the sprite u can mess with the transform of the image

[raw pelican]

@gusty ermine I don't know either. But an idea: for images (UI Image), they are contained within a canvas, which is a game object. Can you make any game object follow your mouse position? Can you make the canvas's game object do the same thing and follow your mouse position?

[gusty ermine]

No I can't

But what I did was I just changed to a sprite and am using that

But now I have another problem

Which is that I actually don't want it to stay where I release the mouse

I want to click, drag, and when I release the mouse I want it to bounce back to it's original position

How do I do that?

[compact knoll]

cache it's original position then you can lerp it back to that position

[gusty ermine]

And how do I do that?

[compact knoll]

which part of that did you not understand?

[gusty ermine]

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

public class DragDrop : MonoBehaviour
{
    private SpriteRenderer mySpriteRenderer;

    public CardController cardScript;

    public GameObject parentObject;

    private Vector3 dragOffset;
    
    private Camera cam;

    private void Awake()
    {
        cam = Camera.main;
        mySpriteRenderer = GetComponent<SpriteRenderer>();
    }

    private void OnMouseDown()
    {
        transform.Rotate(new Vector3(0, 0, 45));
        dragOffset = transform.position - GetMousePos();
        mySpriteRenderer.enabled = true;
    }

    private void OnMouseUp()
    {
        cardScript.OnAdultQuestionClick();
        //mySpriteRenderer.enabled = false;
        transform.Rotate(new Vector3(0, 0, -45));
        
    }

    private void OnMouseDrag()
    {
        transform.position = GetMousePos() + dragOffset;
    }

    Vector3 GetMousePos()
    {
        var mousePos = cam.ScreenToWorldPoint(Input.mousePosition);
        mousePos.z = 10;
        return mousePos;
    }

}```

[compact knoll]

also, use a paste site for large blocks of code

[gusty ermine]

Every bit of it

How do I store the original position then jump back to it?

[gusty ermine]

sorry

I'm a noob I have no clue how to store the location then jump back to it

[compact knoll]

store it as a variable, then you can set the transform.position equal to Vector3.Lerp(positionAtRelease, startingPosition, fractionOfJourney)
https://docs.unity3d.com/ScriptReference/Vector3.Lerp.html

[still tendon]

still stuck on the drag and drop thing?

[gusty ermine]

Yep

I got it sorta working, I switched to using a sprite instead of a button + image combo for what I want, but I now need it to not stay where I put it

[still tendon]

that's what i told u to do

[gusty ermine]

Yea ik

I finally figured out how to actually make the sprite visible on my canvas

[still tendon]

gg

[gusty ermine]

Only 1 check box but still took me an hour to find it lol

idk how to store the original position as a variable @compact knoll

[compact knoll]

transform.position is what you need to store. save it in a variable in your OnMouseDown method

Vector2 startingPosition = transform.position;
You may want to go refresh yourself on some basic C# tutorials as well as some unity tutorials if you aren't familiar with how to store a variable

[gusty ermine]

No ik how to store a variable I just didn't know what I need to store, and what type of variable I needed to store it as

Thanks

Wait a sec

Is there any reason I have to declare it there?

Couldn't I just declare it in the class, set it in OnMouseDown() and then call back to it in OnMouseUp() with transform.position = startingPosition?

Yeah that works perfectly

What's the point in using lerp then if I can just declare it in the class, set it in the function, then call back to it?

[compact knoll]

i mean you absolutely can do that, but lerping will actually move it over time so it isn't an instant teleport because those generally look bad. plus you said "bounce back" which implies you see it move back to the position

[gusty ermine]

Ok so here's what's up. It's a card drawing system, I want to grab the card, move the card, release the card, card goes invisible and goes back to top of deck and only reappears when you click the deck again while an animation plays showing the card in fullscreen

So for now I can see it

But I'm gonna make it invisible most of the time and only appear when you click the card

And for now it's just basic af just to get it working, I'll smooth it out later

[deep granite]

hi im trying to get an object to move and this is the code i used, but it's not working for some reason and im not sure why?

is there a problem with the components?

[gusty ermine]

Uh dumb question but is it because your move speed is 0?

[deep granite]

in the tutorial i was following, they put that as 0 but the object still moved

just changed it but it still doesnt work

[hollow crown]

have shouldn't have two Translate components

and then just try putting in a large move speed value in the inspector

[deep granite]

sorry im kinda new to this, where did i put 2 translate components? @hollow crown

[deep granite]

oh right nvm

@hollow crown thank you it worked!

[still tendon]

https://paste.ofcode.org/XYJERDbPB2knSYDEdvr3Gg <-- this is my catcher movement + score text code but the score part doesnt work instead it gives me an error NullReferenceException: Object reference not set to an instance of an object on line 33 . i get that its not able to find the text component but idk y or how to fix it

[turbid heart]

assign to your Text variable

if you make it public, you can just drag the Text from your scene to the variable field in the inspector

[still tendon]

Sry for the late update but i already fixed the problem

My game is working fine now and it's completed

[dusky wagon]

Will constantly setting the velocity and object to a certain value each frame make it glitch through objects? My object does that and Im not sure if this is the reason or something else

[compact knoll]

It shouldn't, setting velocity uses physics

[dusky wagon]

Does it have it be dynamic? I tried it with the setting and it seems to work

But I dont want it to have gravity or be pushable

[compact knoll]

Yeah it will need to be dynamic. You can also set the gravity scale for the RigidBody2D to 0 as well as its mass and drag

[dusky wagon]

Shouldnt mass be really high?

[compact knoll]

If you don't want it pushed around, sure

Since you're setting velocity directly that won't affect movement speed

[dusky wagon]

Okay thanks!

[meager cobalt]

ive been going trough internet for like 1h
and i havent found how to change bool to true or false and i havent found how to change a float from like 5 to -5

its just myBool = true. I would suggest going through some basic C# tutorials first because that is one of the first things you learn

thanks

what about the Float one

[late viper]

same thing

you assign it the number you want

[meager cobalt]

okay

how could i toggle a boolean @late viper ?

by pressing a button i could switch it on/off

could you try to explain this to a 2 year old german kid? 😂

and no, i dont know the basics of Noise.

however

[dusky wagon]

Oh wow thats so much smarter than what I used to do

[gusty ermine]

I need some help. Basically I'm working on a board game that has trivia cards as a major element. There's 4 types of cards but only 2 are relevant here. There's the trivia cards, and treat cards. Trivia cards is either gain 3 points or gain 0 points depending on whether or not you answered the card correctly, and that's a super easy system that I already have working fine. The problem is the treat cards... Treat cards either give you a special item, give you anywhere between 1 and 6 points, and can sometimes remove points aswell. It can't be random since alot of the penalties/rewards only make sense when read with the card so I can't just randomly put in an amount of points, so I need to store all of the rewards/penalties and when I pull a random card it would give you the reward/penalty/item from that card when you click okay and I don't know how to do that

Right now I'm storing my cards in strings but I don't know how to store instructions in a string instead of just text.

[late viper]

why are you storing cards in a string? why not use a class?

[gusty ermine]

Because I thought a string would be better?

And because I'm a noob and wouldn't know where to start for storing the cards in a class

[late viper]

hmm, maybe go through this first https://www.w3schools.com/cs/cs_classes.php

[tall current]

My child collider is being used by my script on my parent collider, how do I make that not happen?

the colliders join together

[gusty ermine]

Ok but I still don't see how storing it in a class solves my problem of strings with instructions

I have 50 or so cards

Each one needs to be picked at random with its instructions

[late viper]

if you use a class, you can store multiple attributes in the cards that you can use to store things like instructions and points

then you can make a list of Cards that you can just pull and read from

[gusty ermine]

Ok can you write an example for me? Basically "Card text" + add 5 points

card1 = "yeet" += 5 points doesn't work

Or at least if it does idk how to pick at random from card1 card2 or card3

What I'm doing for the trivia cards is storing them in a string and storing the answers in a second string, picking the question, storing the question as I, displaying I, then displaying I from another string

But the treat cards are only in 1 part, and it has to be together it can't be seperate like the trivia

And it' sconfusing tf outta me

[late viper]

so something like

class Card
{
  int points = 5;
  string instructions = "your instructions here";
}

then you make List<Card> cards = new List(); and add cards to the list with Card c = new Card();

[gusty ermine]

Wait so say I have several different cards that give +5, could I list all of those cards off there, then list off all of the 4 point cards etc?

[late viper]

sure

[gusty ermine]

Ok let me put this in and see if I can piece it together

[late viper]

you should probably use a constructor as well. refer to this https://www.w3schools.com/cs/cs_constructors.php

and maybe just go through the OOP section while you're there

[gusty ermine]

OOP?

[late viper]

object oriented programming, aka Class stuff

just go through that section I sent

[gusty ermine]

Do I put this in the card class or in my main code class?

Ohh ok bet

Never heard it called OOP before lol

[late viper]

main code

[gusty ermine]

ok

class card
{
    int points = 5;

    string[] treatCards =
        {"CARD 1 yaaasa \n +5 points",
        "CARD 2 yeetus deetus this card is sexy \n +5 POINTS",
        "CARD 3 YEET \n +5 POINTS.",
        "CARD 4 just a card \n +5 points"};

}```

Where would I go from here

And then where would I go about entering in all of the 4 point cards

Would I use another class with another set of integer + string?

Because that doesn't sound right

Ideally instead of complicated workarounds it should just read the card and add to my global points variable the correct amount of points

I guess technically I'm storing all my stuff in arrays of strings

But w/e

[late viper]

uhh no. You don't want to store ALL your card data in a class. A class is a template that you use to describe a card

[gusty ermine]

wait wut

Wait

[late viper]

so using my card class I wrote above, and assuming you write a constructor for it, what you want is probably:

Card Card1 = new Card (5, "yaaasa");
Card Card2 = new Card (5, "sexy card");
Card Card3 = new Card (5, "YEET");
Card Card4 = new Card (5, "just a card");

[gusty ermine]

Could I make an array of integers pertaining to every single card, then pick the same index from that array as I do from another array?

Might be a lazy workaround but do you think it'd work?

[late viper]

then you can access the data using Card1.points or Card1.instructions

why not just use random on a range of integers

you don't need an array

[gusty ermine]

And this goes in main code not in new class?

I don't want random, I want it to be set for every card

If the card says lose all your points then it'd make no sense for it to take only 5 points

[late viper]

then you can add a field in the class that can be bool losePoints = false;, and check it when you pick a card

[gusty ermine]

No I want every card to be specific

Not random

[late viper]

when I say random I mean when you pick a card randomly

[gusty ermine]

ik

[late viper]

the card properties aren't random

[gusty ermine]

I don't want to randomly pick the card and the points I want to randomly pick the card and have the points be preset

[late viper]

yes I know, I never said the points are random

[gusty ermine]

Then what's the point in a random range of integers?

[late viper]

oh I misunderstood your initial question. I guess it can work but it'll be very prone to errors

[gusty ermine]

Ok fair enough

Okay so summarize

Your code for the array

[gusty ermine]

This in main code

[gusty ermine]

This also in main code

Right?

And if so then what exactly is the point in the class?

I can't figure this out

I'm completely lost

[late viper]

the point of the class is to have an easy way to access the data of your cards without using a bunch of arrays

did you go through the OOP stuff?

[gusty ermine]

yeah

But it just confuses me

I gotta take another course

but rn I jsut want to get this figured out

[late viper]

you can stick to your two array solution for now then, if you just want it working

[gusty ermine]

Yeah I just set that up

Seems to be working fine

And my game is very small so it doesn't really matter if something is poorly optimized it's going to use so little processing power anyway

[winged marlin]

It only uses 2D movement controls right?

[compact knoll]

Modifying the transform for movement bypasses the physics engine. Use a RigidBody2D to handle movement. There are several options you have for that such as Add Force (which absolutely is 2d movement, idk why you would think it isn't really 2d), change the velocity directly, or MovePosition

Ah, add force still works though

you can use one of the other methods, just keep in mind that if you want like knockback and stuff they will be kind of annoying since they all either overwrite or ignore velocity

[magic shoal]

does anyone know what to add to my code so that landed becomes true only when the player lands on a platform (not going through it)

[vocal condor]

On collision exit: landed = false

[visual mural]

Okay guys so I have this following code I know I screwed up with the "Condition or" What I wanted to do was have the character move with arrow keys and WASD. I also wanted to make sure if two keys are pressed at the same time (like W and Up Arrow) the character doesnt move faster

The input works but I know this is a super messy approach

if (!keyPressed) //making real sure you cant speed the froggy up with two directional key presses
        {
            if ((Input.GetKeyDown(KeyCode.RightArrow) || Input.GetKeyDown(KeyCode.D)) && transform.position.x < 8)
            {
                keyPressed = true;
                rb.MovePosition(rb.position + Vector2.right);
            }

            else if ((Input.GetKeyDown(KeyCode.LeftArrow) || Input.GetKeyDown(KeyCode.A)) && transform.position.x > -8)
            {
                keyPressed = true;
                rb.MovePosition(rb.position + Vector2.left);
            }
                
            else if (Input.GetKeyDown(KeyCode.UpArrow) || Input.GetKeyDown(KeyCode.W))
            {
                keyPressed = true;
                rb.MovePosition(rb.position + Vector2.up);
            }
                
            else if ((Input.GetKeyDown(KeyCode.DownArrow) || Input.GetKeyDown(KeyCode.S)) && transform.position.y > -4)
            {
                keyPressed = true;
                rb.MovePosition(rb.position + Vector2.down);
            }
                
        }
        else
        {
            if(Input.GetKeyUp(KeyCode.RightArrow) || Input.GetKeyUp(KeyCode.D) ||
               Input.GetKeyUp(KeyCode.LeftArrow) || Input.GetKeyUp(KeyCode.A) ||
               Input.GetKeyUp(KeyCode.UpArrow) || Input.GetKeyUp(KeyCode.W) ||
               Input.GetKeyUp(KeyCode.DownArrow) || Input.GetKeyUp(KeyCode.S))
            {
                keyPressed = false;
            }
        }

[compact knoll]

You can cut that down a lot by using GetAxisRaw instead of polling each key manually like that

[visual mural]

Oh gosh i forgot about that, thank you

[restive jungle]

I have a game where I want to have a cloud flutter around. I have the cloud at the top of the screen moving back and forth, but I want it to float around this point that's moving back and forth. I already have the parent object moving back and forth, and the cloud is a child object but I want the cloud to float around this point. I've tried using lerp, but it doesn't really look good I don't really know how to describe what I want and can't think of any examples, but i want it to float around this moving point.

[compact knoll]

if you modify the localPosition it will move in relation to the parent

[restive jungle]

I know how to get it to move, the problem is getting it to float around it

[still tendon]

I am having some trouble finding resources for this, but how can I detect if a player has made a building? I have a 2d grid made out of gameobjects called tiles. I tried looking into Flood-Fill, but that's not exactly what I'm looking for. Basically, I'm looking for a system similar to RimWorlds house detection
Each tile has an id, 0 for road, 1 for wall, 2 for floor

[compact knoll]

use the localPosition to "float" around the parent object. unless by float you do not mean to move around the parent object while the parent object moves, in which case i'm going to need you to explain better

[restive jungle]

yea I am moving the child's position around the parent's position, that I can do just fine, I can't make it look good though

[compact knoll]

if it's a matter of it moving around the parent object in a good looking/fancy way then animate it

[compact knoll]

bro quit spamming. read #📖┃code-of-conduct

[deep granite]

can someone tell me why this is happening??

it only happens when the bounciness of the materials is above 1

and this is the code

[compact knoll]

bounciness is a float from 0 to 1
https://docs.unity3d.com/Manual/class-PhysicsMaterial2D.html
going above 1 breaks physics

[deep granite]

oh whoops, thank you!

[dusky wagon]

If I use OnCollisionEnter2D, is there a way of detecting where the collision happened?

[fleet sundial]

someone knows why the script to jump and go horizontally does not work (the game is in 2D)

[dusky wagon]

You shouldnt check for input in fixed update

Check for it in Update instead

@fleet sundial

[fleet sundial]

ok

[compact knoll]

you can get the contacts for the collision, this has the different methods and properties available
https://docs.unity3d.com/ScriptReference/Collision.html

[dusky wagon]

I assume the point property is the thing I need here? I cant tell from the documentation, but it seems to be a Vector3 so that sounds right

[topaz axle]

yeah it should be point

[dusky wagon]

Alright thanks

[fleet sundial]

sorry @dusky wagon I am a beginner in programming (and French) I followed this chain for the code and copy paste the code he put in his github https://github.com/TUTOUNITYFR/creer-un-jeu-en-2d-facilement-unity/commit/db4deb8b8fe9dd47ee0ce2fc0a0da8b008d741a9 (at the bottom of the page) all that to say I didn't understand at the moment i'm coppie sticking on google translation

[dusky wagon]

Just move the check for the Pressed Jump Key from FixedUpdate to Update

[fleet sundial]

ok thanks

[compact knoll]

that's not actually necessary, it does make getting input snappier though

[dusky wagon]

But doesnt it miss some inputs if you check in fixewd update?

[topaz axle]

yeah exactly

[dusky wagon]

The higher the frame rate the more key presses it will miss

[compact knoll]

it can that doesn't mean it will. This is just polling the value of the axis though so it won't miss that

[fleet sundial]

like that

[topaz axle]

yea

[compact knoll]

physics calculations should go in FixedUpdate, not Update. Make a separate Update and FixedUpdate function, put the input stuff into Update and everything else in FixedUpdate. Also you would need to make horizontalMovement a class level variable.

[wind trellis]

yo i need some help
i use unity 5.6.7f1

and
i want to import the post processing package but it is removed from the assets store
and i don't have the package manager so
is there any way to install it manualy

like

idk

[topaz axle]

dont they have a git repo with it or am i dumb

[wind trellis]

um wait

[topaz axle]

https://github.com/Unity-Technologies/PostProcessing

this

you can grab 2.1.8 and youre good

[wind trellis]

yeah
how can i install it manualy dammit

[dusky wagon]

How exactly does the GetContacts method work? I would assume that it returns all of the contacts, but it seems to take contacts as an argument and return an integer

[topaz axle]

throw in the PostProcessing folder in your assets folder

that contains the necessary files

[wind trellis]

ok i think

[compact knoll]

you'll most likely want to use collision.contacts[0].point to get the first contact point

[dusky wagon]

And a foreach loop if I want to get all?

[topaz axle]

yeah

[karmic kettle]

hi there every one.hope you guys are doing fine,i'm kinda stuck at this thing if anyone could help i would really appreciate it.so the idea is that there is a map with multiple cities and each city has a capacity and a unit regen...when i click on my city i want it to get selected and then i click on an enemy city and i want troops to be lunched towards that enemy city.how can i make the lunching part in unity?

[topaz axle]

OnMouseClick() should do the job

[karmic kettle]

the question is how to do the section 5

im using entitas btw

[dusky wagon]

It says:
You should avoid using this as it produces memory garbage. Use GetContact or GetContacts instead.
In the manual which is why I didnt want to use collision.contatcs. Do I have to worry about that? The article is about 3d and I am in 2D but Im not sure if that will make a difference

[compact knoll]

you can use GetContact(index) instead to avoid the memory garbage. my bad i forgot about that

[topaz axle]

you can add to the transform.position of the troops the direction between them and the enemy

syntax should be like:

in the troop script:
transform.position += (enemy.transform.position - transform.position).normalized * Speed * Time.deltaTime

[dusky wagon]

And what would I do if I want to get all of them? I cant use a foreach loop for that, can I? That is why I tried the GetContacts method, but it doesnt work as I expected

[topaz axle]

for loop

[dusky wagon]

Do I first have to get the count and then do a for loop to cycle through each contact?

Oh yeah

[compact knoll]

for loop using i < collision.contactCount for the condition

[karmic kettle]

owww don't know why i didnt think of that

i think this should do the trick

thanks my g

[topaz axle]

yw

[karmic kettle]

this entitas thing is really a pain in the ...

[wind trellis]

another problem

what script do i use

[topaz axle]

uhh layer and volume iirc

like
post process layer and post process volume

volume contains all the effects you want to apply and layer tells on what layers it should render the volume
i used to set it to everything since i wanted it to render on everything

[wind trellis]

ummm can i send photoes here?

[topaz axle]

yeah

[wind trellis]

what tha

[topaz axle]

this

and this

they have the editor counterparts that tells unity how to show the scripts in the inspector

but you want to use the ones i sent

[wind trellis]

what what i don't have those scripts

why

[topaz axle]

check the runtime folder

[wind trellis]

why the hell unity doesn't mport those scripts

[dusky wagon]

Whats the best way to detect on which side of a box collider a collision happened? I tried

if (collision.GetContact(i).point.y >= transform.position.y + 1.999)

As the box collider is exactly 2x2 big but it doesnt work

[still tendon]

use 4 edge colliders

ez

[dusky wagon]

Is that a good way?

[still tendon]

idk i just said it off the top of my head

https://gamedev.stackexchange.com/questions/97993/detecting-on-which-side-did-the-objects-collided-unity-2d

maybe this'll work?

[mint geyser]

you could get the normal of the contact point: ```cs
Vector2 normal = collision.GetContact(i).normal;

[dusky wagon]

Thanks to both of you, I got it to work

[idle mountain]

So im having this weird thing, where when I jump normally, the falling animation doesnt play, but when im running and jumping, it plays

Thats my code

Id love if I could get some help

[dusky wagon]

I think we rather need the animator than the code

@idle mountain

[idle mountain]

let me check now

heres the animator

[wooden ruin]

is there an easy way to apply velocity in the direction a sprite is facing? (not transform.translate, I mean actual velocity)

oh i just made somthing that did that exact thing

ill copy paste the code

mouseWorldPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            mouseWorldPosition.z = 0;

            directionToMouse = (Vector2)(mouseWorldPosition - transform.position);

            directionToMouse.Normalize();
            transform.rotation = Quaternion.AngleAxis(Mathf.Rad2Deg * (Mathf.Atan2(directionToMouse.y, directionToMouse.x)), Vector3.forward);

probably something else i missed so if you have any questions just ask

[dusky wagon]

Im moving an object with

rb.velocity = (idlePos.position - transform.position).normalized * retreatSpeed;

I want it to move towards a point and stop once it hits that point. It works but when the velocity is too high it jitters a lot because it shoots over the point and then goes back to it. Is there an easy way to make it not go over the point? The only thing that comes to my mind is reducing the velocity once the object is in a certain distance from the target

[wooden ruin]

oh

can you elaborate on "doesnt work"

at all?

[wind trellis]

i just downloaded unity 5.6.7f1 and i have SO MUCH troubles

[wooden ruin]

well, i have no idea

well yea

its just mouseworldposition

and direction to mouse

[wind trellis]

do you have duplicated scripts in your object

ok

have you locked the rotation?

oh

i ltrl have no idea

ohk

[dusky wagon]

Does anyone have an idea how to fix this? I also set the velocity to Vector2.zero as soon as the object is in a range of 0.02f of the target object, but it seems to just miss that point

[honest python]

My game runs horribly, even when I turn off everything in the scene except my camera, which has no scripts, I only get like 300-400 fps
I'm in unity 2020.3.14f
normally I get 2000 fps on most of my unity games
though they are in other unity versions

even in build it lags

when there's is nothing in the scene except a cursor following the mouse

[honest python]

make it snap to the position of the target when it is in a certain range

[worldly reef]

How complicated are the games running at 2000 FPS? That seems more like an oddity than something you should expect.

[honest python]

pretty complicated

all 23D tho

2D*

well complicated but definetily not heavy for pc

[honest python]

with lots of stuttering as well btw

also in the build

with just a cursor

[worldly reef]

Do you have a video?

[honest python]

I can make one 1 sec

do you see the stuttering

and that is with just a camera and a cursor in the scene

[worldly reef]

Interesting. What's your code look like?

[honest python]

for the cursor?

[worldly reef]

Yeah

[honest python]

public class CursorScript : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        Cursor.visible = false;
    }

    // Update is called once per frame
    void Update()
    {
        transform.position = Camera.main.ScreenToWorldPoint(Input.mousePosition) + Vector3.forward * 10;
    }
}

this is all

[worldly reef]

This might be your problem. Using Camera.main every frame is super inefficient. Make a Camera property and set it to Camera.main in. Something like Camera cam; and then in Start() do cam.ScreenToWorldPoint()

[honest python]

it still stutters even without the cursor tho

will still do it tho

[worldly reef]

https://stackoverflow.com/questions/61993166/what-alternatives-are-for-camera-main

That might be a good reference

[worldly reef]

Let me know, it could be something specific to your computer, but that's all I see so far.

[honest python]

it only happens with this version of unity

but when I try to switch

I get tons of errors

[worldly reef]

What version are you using?

[honest python]

2020.3.14f

#archived-code-general message

these are the errors

[worldly reef]

It seems that a lot of the newer versions of Unity are less stable. I would try recreating your game (or at least the cursor scene) in an earlier version like 2019.4 LTS

[honest python]

ye will do

99% of the game rn is code anyway

[worldly reef]

Good luck!

[honest python]

thanks!

[dusky wagon]

Thanks. I also have a other idea that has to do with things happening in between frames so that it doesnt get caught. Or at least I assume so since it only happens when the object has a high enough velocity.

I made a script that is supposed to detect when you are getting crushed (checking if there is an object on one side of you and another one on the opposite side and one of the two is moving towards you), but when my objects velocity gets too high, it just doesnt detect it anymore.

The relevant code I used for detection is:

// This in Update()
topTouchedObjects = Physics2D.OverlapBoxAll(topCheck.position, topCheckSize,  0, solidObjects);
        bottomTouchedObjects = Physics2D.OverlapBoxAll(bottomCheck.position, bottomCheckSize, 0, solidObjects);
        side1TouchedObjects = Physics2D.OverlapBoxAll(sideCheck1.position, sideCheck1Size, 0, solidObjects);
        side2TouchedObjects = Physics2D.OverlapBoxAll(sideCheck2.position, sideCheck2Size, 0, solidObjects);

And then doing a foreach loop that cycles through each object in each of these arrays in the same frame and does some detecting.
Does anyone have any idea how I could fix this? Should I completely change my system for detecting crushing?

[honest python]

maybe raise ur FixedUpdate rate?

[honest python]

running at 1200fps now without stutter, thanks :)

also glad I did it cuz the interface looks a lot better now

[wooden ruin]

is the best way to have destructible terrain just to have everything made out of sprites or is there some other way i dont know about?

[dusky wagon]

Its running in update though

And I assume I cant make a higher check rate than my frame rate?

[wooden ruin]

nope, fixed update can go faster

[dusky wagon]

Oh okay how do I raise the rate?

[wooden ruin]

somewhere in edit>project settings i think

[honest python]

wait what how the hell would it do that?

but tbh this is not the way to go

what's the velocity where it doesn't work anymore

[wooden ruin]

wait i thought fixed update was like physics updates

[honest python]

it is

but that can't run faster then your fps

that's like doing something in your game every half frame

or less

[wooden ruin]

i feel like ive seen things that said it could but dont take that as fact

[honest python]

?

[dusky wagon]

Not sure what the exact velocity is, but 10 is already too high

[honest python]

maybe just increase the range of where it detects?

[dusky wagon]

Hm yeah but I probably have to make multiple ranges based on the velocity of the object so that it doesnt look weird on skower objects right?

I can do that, I just thought there might be a better way to detect the whole thing

[still tendon]

Hello everyone, I wanted to ask you something, I just started to use unity and I had to create an old-fashioned 2d game, which Template should I use?

[dusky wagon]

Template?

I recommend not starting with a template, whatever that mean, you learn a lot more if you do it yourself

[still tendon]

I don’t understand that kind of template

[dull wraith]

this new code is supposed to fix a bunch of issues when my player walks, but now he can't move at all.

the animations run as if he is walking but he doesn't move

[dusky wagon]

Can you send a screenshot of what you mean?

[still tendon]

I' have turn off mi pc now .

...

[dusky wagon]

Can you describe what you mean then?

[whole kite]

Can someone tell why this code dont work?

[dull wraith]

it's "Vertical" not "vertical"

also it shouldn't be "(0," it should be "(0f,"

[dusky wagon]

I dont know the context but does that make a difference? Im pretty sure you only have to add the f on decimal float numbers

[whole kite]

im tryna make my player move

for a endless runner

[dusky wagon]

Yeah I meant context inside of the code

[whole kite]

https://www.youtube.com/watch?v=U3sT-T5bKX4&list=LL&index=6&t=145s

i used that video for help

but when he add the player script onto the player he get s to choose player speed but it wont let me, and i dont know if it makes any differnce but his code has a lot more colow while mine dont

[dusky wagon]

Unless you renamed it it does indeed have to be „Vertical“ and not „vertical“

[whole kite]

renamed the script?

[dusky wagon]

And the color part just depends on your ide

[whole kite]

kk

[dusky wagon]

No, the input

[whole kite]

i dont think i have renamed it, ocly thing i renamed was the script name to player

[dusky wagon]

Okay yeah then you have to capitalize it

[whole kite]

kk, should it work after that?

[dusky wagon]

Not sure what you mean by the first bit here

Does it not show the field in the inspector?

[whole kite]

in the video he dragged the script on the the player and then in the inspector its a field to change player speed but that dont show up for me

[dusky wagon]

Then you either didnt save the script, or there should be an error in the console

[whole kite]

k i will check that and if it dont work i will let u know, thx

[jovial stirrup]

Hey small question, I'm making a 2D platformer game and I want to check if my characters in on the ground however:

• If I do a raycast from the center of the character, being on the edge of a platform would count as "not being on the ground" and I'm not sure how to get the character size to do raycasts at the both sides
• I can't check with OnCollisionEnter2D with a tag because I could collider with a platform on the side and in that case I'm still in the air

Any idea?

[kindred pebble]

Look into Physics2D.OverlapArea maybe

[jovial stirrup]

I'll try that, thanks

    }```
I'm getting a `` Cannot implicitly convert type 'int' to 'System.Collections.Generic.HashSet<UnityEngine.Vector2Int>'`` error when trying to do ``return openList.Count + closedList.Count;`` and I'm not exactly sure why

[grand coral]

because Count is an int but the return type of the function is a HashSet

so make the return type of the function an int and then it will work

if you aren't trying to return an int it will be more complicated and you'll have to explain the purpose of the function to get help with that

[dusky wagon]

I have a script the detect when an object is being crushed, by doing OverlapBoxAll on all four sides of an objects and then detecting some things in them and it works so far, but when the velocity of the object gets too high, it doesnt detect it anymore and pushes the object into the ground. I could make the detecting radius higher depending on the velocity of the object, but it would never really be frame independent. On my laptop the velocity it breaks at is 8.5

[lilac roost]

Hey so I'm trying to make a wave of enemies swarm the player and have them jump only if their box collider is touching the ground which sets the isGrounded bool to true. My problem is it sets isGrounded to true for ALL the enemies so any enemies that are in the air will still count as grounded even though they shouldn't and end up jumping like 10 times at once. What can I do to keep their isGrounded values separate because at the moment they are all clones of the Enemy prefab.

[dusky wagon]

Did you make the bool static?

If each of them has their own component with the field inside, they should all have a different value for it

[lilac roost]

@dusky wagon no I didn’t make it static at least I don’t think I did. I just wrote a quick separate script that detects the tag “Ground” and sets the bool to true inside of the enemy movement script

So like two enemies spawn in and as soon as they jump the other enemies also jump but all the way to the top of the map

The other enemies that just spawned*

[late viper]

post the script

[dusky wagon]

I might have an idea to fix this, is there a way to detect if an object is i side of another objects collider? With inside I mean for example in a box collider being in the middle of the object

[astral knot]

Hello all I am experiencing a weird technical difficulty, I have it so if you speak to an NPC it will display a dialogue box with dialogue, and if a requirement is met then it will display a different dialogue box and reward an item, this works but for some reason when I try it when entering from a different level, it gives me the Item but displays the old dialogue box, any pointers? fixed :/

[magic shoal]

i get "error CS0019: Operator '&&' cannot be applied to operands of type 'bool' and 'Vector2'",how do i fix it?

[turbid heart]

the way you're checking your velocity in the if statement is wrong. = is for assigning, == is for comparing

[magic shoal]

i got this error now

[turbid heart]

well you clearly dont understand what assigning and comparing is

Hey guys any suggestions on how I can make "blocking tiles" in Unity?
i.e a prefab, when placed on a grid cell, ensures that nobody can walk on that grid cell. The prefab is placeable by a user. Anyone wanna brainstorm with me?!

[turbid heart]

you're supposed to compare if a tag is "platform", and you're supposed to compare if a velocity is 0. Why are you assigning?

and velocity is a Vector3 type, so it really should be comparing against a Vector3, not a float

if statements need a true or false, and comparing 2 values is how you get a true or false. Not when you assign

@magic shoal

[magic shoal]

yeah

[compact knoll]

here's a probably not ideal way, but something that should theoretically work: you could use a tile map, get the current tile that needs to be changed and set it to a tile that has a collider (or rule tile with your prefab)

[oak olive]

Hi. I'm trying to create a bubble shooter game (you shoot your bubble to a hex grid of bubbles, match 3 or more to remove). I'm trying to get a basic scene set up and shoot a ball. OnMouseUp only works on BoxColliders so I made a background image that's a box collider. I don't want the player to touch the bubble they're going to shoot, but point where it should go. I can calculate the right direction, but because the ball also is a collider/rigidbody it kind of slithers off screen instead of shooting upwards. Is there a better way to get those mouseup events than a huge box collider in the background?

[grand coral]

you could put the objects on separate layers and remove collisions between those two layers if that is the issue

[oak olive]

Ah, that makes sense. Let me try that! Kudos.

[grand coral]

you could also maybe use an event trigger instead of a collider if that doesn't work

[oak olive]

No, that doesn't work. Maybe it's not an issue with the colliders.

[snow bear]

I thought of that but there are some issues with that approach. Tilemaps is bad because I need an additional layer of functionality on each tile. i.e only people with certain roles can be allowed to pass through a tile.
Now do you think a prefab is better?

[compact knoll]

Rule tiles can have game objects attached to them so the gameobject would do everything, the tile just places the object in the grid.

[snow bear]

I thought rule tiles were something else. (i.e how the sprite must be placed when painting)

[compact knoll]

They can do two things

But seriously though, they are primarily used for tiling rules like you thought. But they can have game objects attached and instantiate the object when they are placed

[snow bear]

interesting. so you're saying I should take the rule tiles approach

what about the prefab approach? Should I make a tile prefab that's the same size as a grid cell and try with that?

[compact knoll]

Technically that's pretty much what you would be doing with rule tiles. But you absolutely could do it without using the tilemaps.

[snow bear]

thing is, I don't mind the tilemap approach. I'm using tilemaps for everything else, so..yeah, it kinda makes senes

I just need to know if it's possible to selectively turn off the tilemap collider 2d for certain tiles (which I haven't found a way to do so far)

[compact knoll]

In that case yeah just use the rule tile approach. No tilemap collider necessary because the prefab you attach to it can handle the collision

[snow bear]

oh, so you want me to create a new prefab and attach it as a game object to the tile in runtime...got it. I will explore the same

[oak olive]

I ended up using simple Input.GetMousebutton en Input.GetMouseButtonUp instead, that seems to work just fine with the background collider removed.

[grand coral]

ok awesome

[dusky wagon]

Like said before, you need to use == to compare things and = for assigning values, not the other way around

[magic shoal]

fixed it already but thanks

[dusky wagon]

Oh okay

[dusky wagon]

For some reason, one of my objects doesnt show up in a OvelapBoxAll method call and I cant figure out why. Im probably just really stupid but I dont see why it isnt showing up.

if (Physics2D.OverlapBoxAll(upperCrusherPosition1, new Vector2(1f, 3), 0, ground).Length != 0)

This is how I am checking for the object. It detects everything, except my tilemap

[still tendon]

hey does anyone want to help wiht my shooting joystick?

it doesnt work atm

and this is the code

//using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class ShootJoystick : MonoBehaviour
{
    public float angle;
    public Joystick shootJoystick;
    public GameObject Bullet;

    [HideInInspector]
    public bool canShoot = true;
    void Update()
    {
        if (Input.GetMouseButtonDown(0) && canShoot)
            Instantiate(Bullet, transform.position, Quaternion.identity);
        if (1 > 0)
            Rotation();
    }
    void Rotation()
    {

        if (shootJoystick.InputDirection != Vector3.zero)
        {
            angle = Mathf.Atan2(shootJoystick.InputDirection.y, shootJoystick.InputDirection.x) * Mathf.Rad2Deg + 90;
        }
    }
}

[turbid heart]

Define “Doesn’t work”

[still tendon]

this code is supposed to make it so that if you move the joystick, your camera player will shoot in that direction, and will also turn to that reaction

and the code doesn't do any of those

[turbid heart]

Have you assigned it to a GameObject ?

[still tendon]

yes

this angle thing also inst supposed to pop up

[turbid heart]

Do you have any errors

[still tendon]

no

[turbid heart]

It’s a public float, it is supposed to show up

[still tendon]

do I have to make it private?

[turbid heart]

Or add a hide in inspector attribute like you did for your other variable

[still tendon]

like this right?

[turbid heart]

I dont know if it’s being referred to by other classes so only you can decide if you want it to be private

Try it and see? I’m not a compiler

[still tendon]

yeah the angle thing is gone

[turbid heart]

Idk why you’re bothered by it being exposed in the inspector though

[still tendon]

nah, dont mind that

[turbid heart]

Try debug logging in your if statements. If it doesnt print, means your condition checking is wrong

[still tendon]

I need to put like log before it right?

[turbid heart]

In it. You want to check if it actually evaluates to true and the logic actually runs

[still tendon]

what expecially do I have to type in it?

[turbid heart]

Whatever. You just want to check if the code actually runs, so just print anything

[still tendon]

yeah, but I need to like put

log. something

in the code

[turbid heart]

I said whatever

Debug.Log(“this code is running”);

[still tendon]

in which line?

[turbid heart]

Whatever if statement you want to check actually runs.

[still tendon]

yeah i know

if I wanna see if line 25 runs

where do I need to put the debug.log

[turbid heart]

Do you know how if statements work?

[still tendon]

yes

[turbid heart]

Then?

[still tendon]

do I have to place the debug.log before if?

[turbid heart]

The purpose of the debug log is for you to see if it gets printed when an if statement is true and thus runs the logic

[still tendon]

yes

[turbid heart]

In this example, if your if statement is true, line 27 gets run

[still tendon]

yes I know

[turbid heart]

Using that logic, if you want to know if line 27 gets run, where do you put a debug log

[still tendon]

ine 27?

??

[turbid heart]

If the if statement is true, would line 27 run?

[still tendon]

yes

[turbid heart]

If you have a shred of basic programming knowledge here, this is a no brainer

Then?

[still tendon]

its false?

[turbid heart]

https://www.w3schools.com/cs/cs_conditions.php

Once you know how if statements work, use debug logs to narrow down the logic that isnt being run

Then you can find out which part of your code isnt being run, and why

[still tendon]

I know how if statemens work

[turbid heart]

I’ll put it simply one more time. If your if statement is true, the code in its block will run. So check if your if statement really is true by seeing if a Debug Log prints.

[turbid heart]

You’re saying your code doesnt run. I’m not going to fix your entire code for you, but i can guide you on how to narrow down the problem

[turbid heart]

Like your first if statement in Update. Is GetMouseButtonDown and canShoot actually true?

If it’s true, the code would run. If not, find out why

[turbid heart]

I dont care. You debug log to see if it’s actually run. Would be easier if you didnt actually hide the variable so you can see it in the inspector

[still tendon]

I did this

did I put it at the right spot?

[turbid heart]

Ffs yes

If you know the objective you’d know if it’s right

[still tendon]

well, it didnt print

so it doesnt work

This is probs the problem

to get it called, I made that little thing

[turbid heart]

Is that seriously checking if 1 is more than 0

1 is always more than 0. That if statement is useless

[still tendon]

how am I able to let it run when I want to then?

[turbid heart]

I don’t know, use your own logic. You clearly don’t control when 1 is more than 0

Unless you can change how numbers work

You should use curly braces for your if statements even if they’re one liners. Less prone to logic problems

[turbid heart]

When do you want it to run?

[still tendon]

when you move the joystick

[still tendon]

I mean this

[turbid heart]

Then use something like this if statement

[still tendon]

thats the part that is IN void rotation

[turbid heart]

I said use something like that

[still tendon]

will

[turbid heart]

When you move your joystick you probably get a vector3 or something that gets assigned to a variable

[still tendon]

if (shootJoystick.InputDirection != Vector3.zero)
rotation();

work

[turbid heart]

Then check if that variable is not zero

[turbid heart]

@still tendon

I’m done trying to help. You’re putting in little to no effort to help yourself

[still tendon]

I am trying

but thanks

[still tendon]

does anyone else wanna help me with the if statement?

[woeful sentinel]

NO!.. now scram!

JK

don't ask, just post your code n question

[still tendon]

uhm

//using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class ShootJoystick : MonoBehaviour
{
    [HideInInspector]
    public float angle;

    public Joystick shootJoystick;
    public GameObject Bullet;

    [HideInInspector]
    public bool canShoot = true;
    void Update()
    {
        if (Input.GetMouseButtonDown(0) && canShoot)
            Instantiate(Bullet, transform.position, Quaternion.identity);
        if (1 > 0)
            Rotation();
    }
    void Rotation()
    {

        if (shootJoystick.InputDirection != Vector3.zero)
        {
            angle = Mathf.Atan2(shootJoystick.InputDirection.y, shootJoystick.InputDirection.x) * Mathf.Rad2Deg + 90;
            Debug.Log("runs!");
        }
    }
}

and im trying to make the If statement before the void rotation work

lol

but I dont know which if statement is gonna work

[turbid heart]

Gee whiz, i wonder how can you test. How about with Debug.Log?

[still tendon]

that doesnt solve the problem, about which I need to use

[orchid pewter]

is there a way to do 100% zoom in scene window?

[stoic moon]

is there a rigidbody2d equivalent for this code:```cs
transform.Translate(Vector2.right * moveSpeed * Time.deltaTime);

[turbid heart]

Look up 5 ways to move gameObjects in unity. There’s a video

[stoic moon]

neat, imma look at that thanks

[dusky wagon]

How can you make an object that applies velocity to any object that it colllides with and makes the object bounce away

But not in a certain direction, just pushing it away from the object

[distant pecan]

remove exit time on the transition and fixed transition depending on your needs

[olive mesa]

You could try a Physics Material 2D and set the bounciness super high

[nova bear]

what's the simplest way to rotate a gameobject on its Z axis?

using transform.

[olive mesa]

@dusky wagon You could also try something like this:

void OnCollisionEnter2D(Collider2D other)
{
    Rigidbody2D otherBody = other.GetComponent<Rigidbody2D>();

    if (otherBody != null)
    {
        otherBody.AddForce(otherBody.velocity * -1f, ForceMode2D.Impulse);
    }
}

[olive mesa]

transform.Rotate(Vector3.forward * *rotation speed*);

[nova bear]

ty!

[olive mesa]

Try that

np

[nova bear]

ok

[olive mesa]

Oh, and since this is an every frame thing, I would multiple it by Time.deltaTime as well

If you want custom rotation axis you could also use a public vector3, set it to whatever you want, and use that

[nova bear]

does transform.Rotate(vector3) add rotation or set rotation?

[olive mesa]

I believe it adds

[nova bear]

how can I set rotation?

[olive mesa]

transform.rotation = *Some Quaternion*;

If you want to use a vector for rotation, you can do that with transform.rotation.eulerAngles

[nova bear]

ok
