yes it probably is from the camera

[deft gazelle]

hey guys

I have a problem with this:

float zRotation;
Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
float diffY = mousePosition.y - transform.position.y;
float diffX = mousePosition.x - transform.position.x;;
zRotation = Mathf.Atan2(diffY, diffX) * Mathf.Rad2Deg;
transform.Rotate(new Vector3(0, 0, zRotation));
Debug.Log(mousePosition.x + " " + mousePosition.y);

mouseposition seems to stay the same , even though i move my mouse

[foggy orchid]

thanks you were right

can someone explain to me why the else is functioning right.. the player is rotating back to normal angle over time.. but the top one just turns the player 180 on the head if its on an angle

the commented code it the working one just without rotation over time

is lerp only returning 2 values?

[serene wolf]

So I've now been trying to make the idle animations for my character and I've once again followed the exact steps on that tutorial, and somehow when I move on any direction it doesn't display the animation I want my character to have. I've checked the idle animations again and there was nothing wrong with them. Could someone help me with this? I really do not know how to fix this, since this is not an actual error

[solemn latch]

@serene wolf are the floats in the animator changing? (Would be a lot easier if you posted the code and a screenshot of the animator; on my phone I can't really pause video or zoom in so it is hard as hell to actually see anything)

[serene wolf]

this is the animator

and I suppose I can just type in here the code..?

[solemn latch]

Use a pastebin

Unless it is just a couple lines

[serene wolf]

how do I use pastebin??

sorry I'm just new to all of this

[solemn latch]

You go to any one of dozens of sites that let you paste text files, then share the link here

So in play mode are the floats in the animator changing when you move?

[serene wolf]

https://pastebin.com/FeqBSYhK

[solemn latch]

I noticed that you're using raw input instead of input?

[serene wolf]

yes

it is supposed to give it a more "old zelda" vibe

[solemn latch]

I'm guessing that the problem is that you set both floats to change.x

[serene wolf]

the what

are you kidding me

alright give me a moment

[solemn latch]

It happens =p

[serene wolf]

oh come on....

I feel really bad when I waste a lot of my time and other people's time fixing this begginer problem...

well, thanks a lot anyways

I think I'm just not used to checking the spelling and following the tutorial really quickly

[solemn latch]

You would be amazed at how often absolutely brilliant coders do that exact sort of error.

Typos happen

[serene wolf]

well I ain't any brilliant coder

I've started coding literally 3 days ago

I guess you can really see that by these begginer questions Lmao

[stone bobcat]

do u guys know any free asset to pick an image from gallery and transform to texture 2d ?

[knotty barn]

@stone bobcat Don't crosspost.

[wicked wasp]

I resolve the problem with the bullet

Now it shoot right

[white egret]

how can I make a square move when I click on the button

[vocal condor]

Google Unity movement tutorials and select one that best accommodates for your needs.

[white egret]

ok

[reef flare]

is there a channel for particle system?

[vocal condor]

There's a more appropriate channel to be asking that #💻┃unity-talk (I'm not sure)

[lean estuary]

#✨┃vfx-and-particles

[reef flare]

Thanks!

[reef flare]

negative vector is opposite direction right?

[unique storm]

So, I parented health bar to my main character..... My main character rotates by using scale*=-1 ..... But my health bar also "rotates" then.....How do I fix this?????

[honest summit]

try using sprite renderer flipX instead of scale?

[unique storm]

Sure, thank you.....

[south tree]

wondering if anyone knows whats wrong with this code

saying i have compiler errors

or is this wrong channel?

[hollow wave]

Missing opening squiggly bracket on start method

I'm surprised vs didn't give you a red line

[south tree]

none of my variables highlight either

its odd

[hollow wave]

Hmm

[south tree]

i get visual studio before unity

so

not a clue

[hollow wave]

Ahh

[south tree]

might reinstall it from unity ngl

[hollow wave]

Maybe Google how to link them? I'm still pretty new to this all so I'm not sure

[south tree]

ill have a look

[hollow wave]

That'll probably work

Gl

[lean estuary]

@south tree VS config instructions are pinned in #💻┃code-beginner

[hollow wave]

Gg for getting this far without any autofill haha

[south tree]

is that a lot yeah

woop woop

[hollow wave]

I can't live without tab autofilling

[willow current]

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

public class TeleportPlayer : MonoBehaviour
{
    public float waitTime;
    public GameObject destination;

    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.transform.tag == "Player")
        {
            TeleportPlayerAfterWait(collision);
        }
    }

    IEnumerator TeleportPlayerAfterWait(Collision2D collision)
    {
        yield return new WaitForSeconds(waitTime);
        collision.transform.position = new Vector3(destination.transform.position.x, destination.transform.position.y + 1f, destination.transform.position.z);
    }
}

the teleport never happens :( (waitTime is 0.2 seconds)

[inner ferry]

Try to paste yield return at the end of IEnumerator

[gleaming horizon]

I think you need to call StartCoroutine(TeleportPlayerAfterWait(collision)), assuming you're not trying to halt execution for the wait. You should also make sure your OnCollision is triggering properly.

[south tree]

says "myRigidbody" doesnt exist in the current context?

[snow willow]

get rid of the semicolon after Start()

and put the code inside the curly brackets { }

like:

void Start()
{
  // your code goes here
}```

[south tree]

hero thank you : )

[south tree]

just been setting animations up and as soon as I went into play mode i cannot see my character

i set up the idle animations and that worked fine

then i put my moving animations in and now i cant see the character at all?

when i change the z it shows up????

[worldly reef]

In 2D, the Z value can be used to manage layering. I would check the Z on your camera and compare it to your player

I like to keep my camera at a Z of -10

[foggy orchid]

might someone explain to me why the x and y are also doing something? I mean the target rotation is set to the current one how can there someting change?

[snow willow]

transform.rotation.x and transform.rotation.y are not euler angles

you should not treat them as such

those are components of the quaternion

you might want transform.eulerAngles.x

[foggy orchid]

oh okay thanks

the one I used are for vectors?

[snow willow]

no

they are part of the quaternion

but they're not the same as euler angles

they're values between -1 and 1

and they don't correspond to euler angles either

[foggy orchid]

oh okay

thanks

[south tree]

back with animation problems

ive set the correct images for movement. left right and down work

when i go up, the down animation is played but as soon as i stop i am in the idle up model

[split edge]

anybody here has ever used used Collider2D.cast successfully?

About to have a migraine

I am making a 2d platformer, and I have been unfixable issues when trying to use circlecasts with slopes, so I tried to move to casting my capsule collider

my circle cast was able to detect slopes, but for some reason detected walls as ground

now my Collider Casts doesnt even see slopes

it always returns a normal of 0,1

even when standing in slopes

        var direction = -transform.up;
        float distance = 1;
        float angle;

        int maxResultCount = 5;
        var raycastHits = new RaycastHit2D[maxResultCount];
        charCollider.Cast(direction, raycastHits, distance, false);

        if (raycastHits[0].collider != null)
        {
            var hitGameObject = raycastHits[0].collider.gameObject;

            //var origin = charCollider.bounds.center;
            //float newdistance = charCollider.bounds.extents.y;
            //Debug.DrawLine(origin+Vector3.down*distance, , Color.yellow, 10.0f);

            Debug.Log(raycastHits[0].normal);
            angle = Mathf.Acos(Vector2.Dot(Vector2.right, -raycastHits[0].normal) / raycastHits[0].normal.magnitude) * Mathf.Rad2Deg;
            Debug.Log(angle);


            if ((angle > 40 && angle < 140))
            {
                groundNormal = -raycastHits[0].normal;
                Debug.Log("Grounded!!!" + angle);
                isGrounded = true;
            }
            else
            {
                groundNormal = -Vector2.up;
                isGrounded = false;
            }
        }
        else
        {
            Debug.Log("Not Grounded!!!");
            groundNormal = -Vector2.up;
            isGrounded = false;
        }

this is really simple maths and it should work

I actually dont know what I am doing wrong tbh

I am just casting my capsule collider down and checking for the hit normal

it's a extremely basic test scene with a tilemap collider

[foggy orchid]

im not really sure what youre trying to archieve because im pretty bad at coding but maybe this video will help you. its maybe another method of doing your thing https://www.youtube.com/watch?v=QPiZSTEuZnw

srry if its not

[split edge]

yes, this is the method I was using previously

I cant use this due to other complications

[foggy orchid]

oh okay

then cant help you srry

[winter yarrow]

Ok, so i'm trying to program my jump animation using a boolean value. I can get it to work when jumping, but I don't know how to get the animation to stop; it keeps on looping after the initial jump. I want to try and do something like if the velocity = 0, then the animation is set to false. I'm new to unity so i'm sorry if my explanation isn't the best but I could really use some help. Here is the code that's already being used:

using System.Collections.Generic;
using UnityEngine;

public class Actions : MonoBehaviour
{

    public float _speed = 5f;
    public float JumpForce = 1;
    public Animator animator;
    
    private Rigidbody2D _rigidbody;
    private BoxCollider2D boxcollider;
    
    void Start()
    {
      _rigidbody = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        var _move = Input.GetAxis("Horizontal");
        transform.position = transform.position + new Vector3(_move * _speed * Time.deltaTime, 0, 0);
        
        if (Input.GetButtonDown("Jump") && Mathf.Abs(_rigidbody.velocity.y) < 0.001f) /// This makes the jump and animation work
        {
            _rigidbody.AddForce(new Vector2(0, JumpForce), ForceMode2D. Impulse);
            animator.SetBool("KoopaJump", true);
        }

 
        if (Input.GetKeyDown(KeyCode.A))
        {
            transform.eulerAngles = new Vector3(0, 180, 0); // Flipped
        }
        
        if (Input.GetKeyDown(KeyCode.D))
        {
            transform.eulerAngles = new Vector3 (0, 0, 0);
        }
    }
}```

[worldly reef]

I'm no expert on animation, but here's a few things to check. First, check if the animation itself is set to loop. You can click on the object and see that in the inspector. Second, open your animator during run time and where's it getting stuck and what the current values are.

[winter yarrow]

I more so think I need an if statement to set the boolean value to false, but I dont know how I would code that

I dont think its due to the animation looping

also I forgot to mention its a 2d game, not 3d, idk if that changes anything though

[worldly reef]

Checkout coroutines. You use yield return new WaitForSeconds(n) to cause a slight delay before setting it back to false. Or make a timer system by creating an int timer, set it to zero when you set the bool to true. Then every frame add Time.deltaTime to it. When it equals the amount of time you want to pass, set the bool back to false.

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

[winter yarrow]

Okay, so I didn't use your solution, but I finally figured out how to fix it! I just made an if statement that pretty much says if the velocity of the ridgidbody is 0, then the boolean is false (going back to idle)

[worldly reef]

Great!

[unique storm]

How do I call particles from code, and make them run for like a half a second.....

[proper gate]

Can some1 help me to code a animated walking i have and idle, walk and sprint animation and the idle to walk works perfectly now i try to implement the sprint function but the problem rn is that once i pressed shift the player dont wanna stop the sprint animation. I use animator.SetFloat("speed", movement.sqrMagnitude); and true false bool for sprint on/off

[unique storm]

I now know how to do it, but for some reason Particle system takes my transparent background of my image and it shows it as black.....

[unique storm]

material interprets it as black, not the particle system

[white cedar]

isn't this correct to call the animation?

[snow willow]

yep

is it a constant attack though?

or a one-off?

if it's a one-off thing you would normally use a trigger

[white cedar]

it's an npc, when he gets closer to another npc, he has to attack him

[proper gate]

Some1 help me quick with 2D movement animation idle -> walk -> sprint & jump

[white egret]

how to add edges to box collider?

[knotty barn]

Box collider will always be a box. Try mesh collider.

[white egret]

ok

[white egret]

I don't see a way to edit it

in fact I don't see the collider on the object

oh that is around the object

I don't want it to be full size of object

[knotty barn]

You can supply your own mesh to it. You can create meshes with all the traditional tools, including probuilder.

Oh for 2D you probably want polygon collider

[white egret]

oh ok

xd

[proper gate]

How do i stop my character to jump infinite?

[white egret]

add a tag to a ground and then just make a bool and check for collisions with that tag and if it is touching then bool is true and when it is not touching bool is false and lastly if that is true then character can jump

hope I explained it well

[proper gate]

what if my char doesnt really jump its just a animation

but i wanna do it once when i press space

[white egret]

I'm not a pro with unity coding I started few days ago

I just know that

[proper gate]

same

[white egret]

search it up on youtube, google

[proper gate]

im currently figuring out how i save the current character animation

because i try a 2D game like Stardew valley

[white egret]

cool

[proper gate]

but my char doesnt have a going down and up animation so if u walk left and he looks left thenn u press S to walk down he should be left and same as if i walk right than "S" for down he should look right but idk

i only got fixed animation to it so whenever i press S he looks to the right

and idk if there is a simple way to flip the same animation but i have 2 folder with left animations and right animations but they are all the same just flipped xD

[white egret]

I've put this code on my object and in a button but button doesn't work 70% of the time

why?

[snow willow]

Wdym you put it in a button?

[white egret]

put the script in the button

object*

not script

[white egret]

it is something about the ground

idk what

Imma redo the ground

[shadow matrix]

does anyone know how to made it so the player will stop once the movement key isn't pressed?

[white egret]

I'm not a good programmer in unity cuz I started few days ago but I think that rb.velocity should work

[proper gate]

Some1 gonna take a look at my code and tell me why unity is not applying my sprint speed anymore? lol nothing has changed it worked before

[magic junco]

Share the code with us

[magic junco]

Like sekikk.py said, If you are using Physics functions for the movement, you could just put a rigidbody.velocity = Vector3.zero; when the movement axis are not receiving any input

[shadow matrix]

THis is the code

[sacred kraken]

anybody know how to make my player attack by pressing a key
specifically depending on what direction i am facing
it would play a certain attack

like zelda

[still tendon]

please help i want help at script kill part replay player don't work at my game parkour 2D

[magic junco]

For capturing a key you will need to use the Input class. Here are some simple code examples of the Input Manager system: https://docs.unity3d.com/Manual/class-InputManager.html

[sacred kraken]

sooo Input.GetKeyDown

[magic junco]

About the facing direction, you will need to have it stored on some variable. So if your character moved to the right, you need to update its value to represent right. You can do it with an enum containing the directions or even a Vector2 if you prefer math rather than words.

[magic junco]

Yes

GetKeyDown returns true only on the frame the player pressed it

[sacred kraken]

well, i dont really know too much about code so can i get redirected to a place that i could start at maybe

[magic junco]

Yes yes, let me try to find a friendly tutorial that might help

just a moment

[sacred kraken]

sweet

[magic junco]

Well, this is a simpler one but it only covers the top-down movement, I hope it can helps for now https://www.youtube.com/watch?v=u8tot-X_RBI

If you are feeling more adventurous, there is a complete series about a Zelda Clone, might be worth watching. Seems beginner-friendly as well:
https://www.youtube.com/watch?v=F5sMq8PrWuM&list=PL4vbr3u7UKWp0iM1WIfRjCDTI03u43Zfu&index=1

[sacred kraken]

oh yeah ive seen some of that zelda series but i stopped following it because at one point the tutorial didnt work for me

[wicked wasp]

It happened to me but i ask here and they resolve that problem

anyone know how to make a 180* rotation

ONLY 180

[faint sparrow]

transform.rotation = Quaternion.Euler(vector3.forward * 180) ? and depends on how you want it, you can lerp it so its rotating, instead of giving new rotation

[wicked wasp]

thank

[wicked wasp]

i've got this script but it works for 360 *

[wicked wasp]

@faint sparrow

[faint sparrow]

first where you got that code, and from what i see you get that angle from mouse pisition relative to your mouse and convert to angle, and then actually you need to understand what you doing, and if you mean rotate only 180 degree...with that code i dont get the idea, do you want to clamp it?? so can not rotate greater that 180? or what

[wicked wasp]

it rotate over 180

[faint sparrow]

so yes? i dont get the problem...you want to clamp it?

[wicked wasp]

yes

want it to rotate 180 degrees only

[faint sparrow]

im not good person when talking about math and stuff, you can ask where you get that tutorial, or wait for someone else..sorry

[unique halo]

mathf.clamp()??

[wicked wasp]

yes

[proper gate]

fixed it myself but im wondering why there is a difference between writing the if in the update or writing the if in a extra void and give update the void name();

idk why but i think my code is not made in good order, but im new to coding ^^

still cant really decide what should go in update and what in fixedUpdate because currently i have nothing in fixedUpdate

[turbid heart]

there shouldnt be a difference 🙂 also, when you say "give update the void name", what you're really doing is calling the function in Update

your code looks pretty good for someone who's new. there are way worse.

and for Update vs FixedUpdate. I personally don't do alot of physics stuff, so i'm not sure, but rule of thumb is Input stuff is in Update, physics stuff is in FixedUpdate
https://stackoverflow.com/questions/34447682/what-is-the-difference-between-update-fixedupdate-in-unity#:~:text=Update runs once per frame,the difference between the two.
https://learn.unity.com/tutorial/update-and-fixedupdate

but please research and read up on your own more on this topic. it's a very common question so there'll be tons of resources

[proper gate]

Thank u 🙂

The part im figuring out now is, when i sprint and i let go the directional key like W A S D but keep press shift my character stop moving but keep the sprint animation

[plush coyote]

only transition to the sprint animation if your speed is greater than .1f

just add that as another condition

and transition back to idle if speed is less than .1f

[proper gate]

@plush coyote have idle to walking greater/less 0.1 and walking to running shift bool true false

[plush coyote]

yeah, so what's it supposed to do if its in the running state and you arent moving

it just sits there because theres no speed condition on the run itself

just add the same speed condition to the transition between walk and run

so it can only enter the run if the speed is greater than .1f, and it will exit the run if the speed is less than .1f

[deft gazelle]

guys I started Unity 1 week ago(I have some programming experience),in unity I made a 2d game with a player(the square) who can jump , move , shoot , and switch guns .Do you have any ideas of what i could do next?(something that would make me learn new things would be great)

[proper gate]

u draw characters?

[proper gate]

it would be easier if the speed parameter value is 1.0 when i walk and 2.0 when i sprint

[deft gazelle]

No , i just use some sprites , squares , circles

[proper gate]

Oh wait i think i have it

this is so confusing

[hollow wave]

Hi all is there a way to basically regenerate my tilemap around a Vector3 position - basically my camera will move rts like and I just have a hex map (not really used other than to show the 'grid' ) and I want to show it always

using the 2d tilemap system

[magic junco]

Taking complete tutorials on the web and doing Unity Learn courses https://learn.unity.com/ are a good way to go. I mean, even if you make a game mechanic from a genre that you dont like, you will probably learn a lot by doing.

[magic junco]

You can move the Tilemap object's transform for that position

[brittle hollow]

hi all,

Im being quite vexxed by the idea of keeping everything appropriately scaled with screen resolution in a 2d game that operates with a static background image.

For example, consider the below screenshot.

Lets say that I wanted to have a bottle of beer thats always on top of the rightmost arcade machine and be a clickable, interactable object. But because its a background image, if the resolution changes then some of it can get cut off. How would I handle that scenario without creating black bars at the top and bottom of the screen etc.?

To reiterate, im having trouble understanding how to keep all elements on screen and in their proper place with a changing camera resolution in a 2d environment. Any thoughts?

Here is perhaps, a better example. Here is my game in 16:9

you can see the bottles on the left rack are visible

swap that to 4:3 and

the way I have scaling set up, the camera scales down a bit, sacrificing some background image to keep from having black bars left/right or top/bottom to match the resolution

am I just handling my scaling like an ape, or is this a common problem?

The issue im running into is, if I wanted to have interactable items in the background, but belong in a specific place in that background, how would I scale my environment to ensure they dont get cut off and remain in their proper place. Like a beer bottle on the counter

[white egret]

I want to create endless runner in 2D and I'm trying to follow CodeMonkey's video about it and I have a little problem. In the video he is using parents origin places and than scaling the childs to the place, but I can't do that because I can't scale it because that will mess up the texture. Any ideas on how I can do it?

[turbid heart]

why can't you scale it?

[white egret]

cuz it will mess up the texture

[hollow wave]

Is the issue that it's squashing / stretching the texture?

[white egret]

exactly

[hollow wave]

The only solution I can think of rn is to generate a texture from a base texture and change the area of the texture you sample depending on the scale of the object.

But that's probably not what your looking for

[white egret]

nah, to complex

[hollow wave]

I got nothing then

[white egret]

sadness

[frozen anvil]

Is there a way after I use RigidbodyConstraints2D.FreezePositionX I can unfreeze the X Position again without using GetComponent<Rigidbody2D>().constraints = RigidbodyConstraints2D.None; because that also unfreezes the rotation

[white egret]

try this

rb.constraints &= ~RigidbodyConstraints.FreezePositionX;

[unique storm]

So I made an animation in premier pro..... All the pictures I use had transparent background, but when I use that in Unity, the background isn't transparent, it's black..... Why is that????? The same thing happens when I use just on of those pictures..... .....

this is the picture.....

[snow willow]

Make sure you're using input alpha as transparency in the image import settings

[unique storm]

Thank you, one more question, do I change that in the settings of my drawing software or Unity?

[misty vine]

And don't forget to hit apply after

[unique storm]

Thank you a lot.....

How do I do it with animations?

[snow willow]

The animation itself shouldn't know or care about the sprite transparency

[unique storm]

This is my animation

When I apply I see black around it

[delicate loom]

Anybody find out how to set tile color for a tilemap?

I can set the color, and it returns the correct color, but the tilemap simply renders as if no color was set

Using URP btw

@delicate loom try tinting the material

[solid island]

hey guys i was wondering if there was a way to detect the same button twice within a time period to execute a command

i know what i want isnt clear but basically i want to detect the double press of a button in a period of time

anyone can help?

[snow willow]

Just save the current time when the button is pressed and subtract the previous time it was pressed

if the difference is < some threshold, do the thing

[solid island]

one moment lemme process what u just typed

i allready made a float and multiplied it by -time.delta time

[snow willow]

why

[solid island]

so now that float's number should be decreasing correct?

[snow willow]

Imagine you're a computer. SOmeone presses your button. You look at the clock. It's 3:00.

You write down 3:00

later, someone presses the button again

you look at the clock

it's 3:16

you look at what you wrote down earlier

it says 3:00

you subtract

you get 16 minutes

Is 16 minutes less than the predefined threshold?

if yes - do the action

if no - just erase 3:00 and write 3:16

[solid island]

well what i was thinking of doing is if float is more than zero && getbuttondown again then it should execute the command

[snow willow]

just pretend Time.time is the clock

[snow willow]

which float though

[solid island]

the one that is multiplied by -time.deltatime

[snow willow]

I don't understand the multiplying by -time.deltaTime thing

what is that supposed to do

[solid island]

make the number decrease i think

[snow willow]

i mean... it multiplies it by a small negative number

that's all it does

[solid island]

wait what?

my bad then i guess

[snow willow]

Time.deltaTime is just a number

usually a pretty small one

around .016 if you're at 60FPS

[solid island]

then how do i make it decrease gradually as time passes

??

[snow willow]

well if you want to make your own timer

you make a float that starts at 0

and just add Time.deltaTime each frame

But there's already a timer that does this

Time.time

[solid island]

please do keep in mind that i just started so im a little dumb

learning unity that is

anyways how would i use time.time in this situation

[snow willow]

Like this: #🖼️┃2d-tools message

that's a metaphor of course

think of Time.time as the "clock"

and a float variable as the piece of paper where you write the time down

[solid island]

yeah i get the idea but

the idea isnt gonna do much for me if i dont know how to code it out u know?

[snow willow]

Maybe give it a try

see if you get stuck

[solid island]

ill look in the unity documents

thx

so time.time is basically a timer that is always active right?

[snow willow]

yes

[solid island]

hmmm im not so sure if ill be able to use it but ill see where it takes me

maybe ill reach my goal

[quick hornet]

Hey all, could use some help... I have a game object (eyes) that is the child of another game object (head) and I'm trying to clamp the local rotation of the eyes between -45 and 45 degrees on the Z axis. This is my code:

    public static Quaternion RotateTowardsOnZAxis(GameObject target, GameObject current, float degOffset, float rotationSpeed)
    {
        Vector3 difference = target.transform.position - current.transform.position;
        float targetZ = Mathf.Atan2(difference.y, difference.x) * Mathf.Rad2Deg;
        return Quaternion.RotateTowards(current.transform.rotation, Quaternion.Euler(0f, 0f, targetZ + degOffset), rotationSpeed);
    }

...        

  _leftEye.transform.rotation = RotateTowardsOnZAxis(_player, _leftEye, eyeImageOffset, _eyeRotationSpeed);
  // here's the problem
  _leftEye.transform.localRotation = Quaternion.Euler(0f, 0f, Mathf.Clamp(_leftEye.transform.localEulerAngles.z, -45f, 45f));

The problem is transform.localEulerAngles.z doesn't return consistent values between -180 and 180. So for example sometimes I'll get 359 instead of -1, and that breaks my clamping function. I checked the documentation and they suggested we use the Quaternion * operator instead, but not quite sure how to translate that to do what I want to do.

[quick hornet]

did some googling and found an answer!

//return angle in range -180 to 180
float NormalizeAngle(float a)
{
    return a - 180f * Mathf.Floor((a + 180f) / 180f);
}

Hey guys, wanted to pick your brains a bit. I'm building a top down 2d JRPG type game, and am trying to implement jumping (same implementation as they have in the Mario and Luigi series). I got the sprite animating (increasing y and z values to account for depth), and I put a collider on the shadow of the main character, but am having issues jumping "on top" of the platforms. I can disable the colliders once the player reaches a certain z value, but am uncertain how I should set the players new z position once they land

[light elk]

hey how to make cinemachine follow my player on spawn?

player game object is not on scene

and i want it like that

[knotty barn]

@light elk The spawner could make that connection whenever player object is spawned

[light elk]

so i assign the spawn point instead of player?

but sapwn point does not move with player

[knotty barn]

No, I meant have the spawner somehow pass the spawned player object reference to the camera

[light elk]

https://controlc.com/813c5303

i found that online

[knotty barn]

Well that also works

[light elk]

not working

[knotty barn]

Is the player object tagged?

[light elk]

yeah

https://gyazo.com/091b613bbda0f5f8742a1b9fc6a32355

[knotty barn]

What happens to the tPlayer field in play mode?

[light elk]

fixed it

i have habbit of assigning it to prefab

in here u don't need to assign from start

it finds target

my bad

[knotty barn]

Yea that would screw it

[light elk]

thanks

[knotty barn]

Ideally you would not have this sort of field visible in the inspector

[light elk]

need break i guess

[knotty barn]

Either could make it private or just use [HideInInspector] attribute on the field

[light elk]

yeah i can do that

[fast siren]

is there something wrong with this?
Text text;
i keep getting this error

[hollow crown]

Add the namespace Text is in, your IDE should be able to suggest that for you

If you're using VS you may need to properly configure it https://docs.microsoft.com/en-us/visualstudio/gamedev/unity/get-started/getting-started-with-visual-studio-tools-for-unity#configure-unity-to-use-visual-studio

as the error should be underlined in red

[fast siren]

wym add the namespace text is in.

[hollow crown]

if you configure VS you can click the yellow lightbulb when the error is selected and it will suggest namespaces you can add

[fast siren]

ok it fixed it

Hey, does someone know how to make like a 2d platformer slippery movement?

[hollow wave]

Create a new Physics Material 2D and adjust the friction value. Set the new material as your rigid body's physics material to have the material effect all attached colliders or if you just want it to effect a specific collider on an object just apply the physics material to that collider and not the rigidbody

[fickle kiln]

stupid question but how do I create a background image for a puzzle game? I want to have a grid ontop of it so I can place tiles as well. I tried just creating a new object with an image component and then attaching a source image but it's not showing anything

[slender lark]

Heyo

How do I go about recognising the tags of game objects separate from the parent

Here i have 4 Sword objects that float around my character and are enabled and disabled

When these collide they are recognized as the parent object

[dreamy verge]

I Hope this is the right channel, first of all hi guys!
I wanted to make an zelda like game with unity , im at the very start , i tried to put collisions on 2d objects and when i try to touch them with my character, my sprite bouncing back and the console give me this error:

But i dont know why, i didnt touched that script

[jolly hawk]

How can I attach a audioclip and audiosource to Scriptable object? How can I play a sound on when specific function starts working on scriptable object?

I have managed to attach them but cannot add audio source

[last surge]

How does a particle system work ?
I need the effect in my game window but when i click play all i see is just the background. Please help

Note: i haven't done any layering

[hollow wave]

https://youtu.be/FEA1wTMJAR0

[last surge]

No problem is that the particles are just not showing

I added them edited them and changed them for my game but it just wont show when i click play

[turbid heart]

are they set to play on awake?

[last surge]

Yeah

[turbid heart]

can you try this to see if it's actually emiting particles? move the system to outside your background and away from anything that can block it. When you press play, go into your scene view and see if you can see it emitting there

[last surge]

Yeah its working its making the particles and i have no sprites over it

[turbid heart]

oh, then you'll need to give it a sprite. I think it automatically creates a material for it as well when you do that

Wait, I misread what you said

in that case it's probably the layering then. look at the renderer section of your particle system and set the layer there @last surge

[last surge]

Do i need to add different sorting layers?

[turbid heart]

that's up to you. you can either use different sorting layers, or just change its order in layer

[last surge]

Its on the sorting layer defualt and its on order 1

[turbid heart]

sorting layers and orders are very easy to understand. please read up on it on your own if you havent

[last surge]

Umm what ? Setting the z position to 1 worked

[fickle kiln]

why might the onDrop function not do anything here? https://pastebin.com/hMQ1VUMm

[snow willow]

You need to spell and capitalize your functions correctly

oh wait sorry you did

just not in discord 😄

when you say "do nothing" what do you mean?

Is the code running?

[fickle kiln]

ok actually my bad it is working, just wasnt seeing the debug messages - for some reason it's printing item dropped before end drag

ok I'm being dumb ik but why is this snapping my images to the same place on a 100x100 grid

    public void OnDrop(PointerEventData eventData)
    {
        Debug.Log("Item Dropped");
        var currentPos = transform.position;

        transform.position = new Vector3(Mathf.Round(currentPos.x) / 100    ,
                             Mathf.Round(currentPos.y) / 100,
                             Mathf.Round(currentPos.z) / 100);
      
    }```

[snow willow]

are you meaning to multiply by 100 again at the end?

i'm confused about the division by 100

[fickle kiln]

nah it's supposed to be divided https://forum.unity.com/threads/in-game-snap-to-grid.77029/

[snow willow]

you're not followihng that correctly

you need to first divide, then round, then remultiply

[wild current]

is there a way to send out a signal to all gameobjects with a specific tag attached that they should move up a specific amount?

Ive been trying to figure this out for like 4 hours any help appreciated

m using this to move them

I have them all stored in an array too if that helps

the array updates so whenever a new gameobject gets the tag its added to the array

[magic junco]

Yes, there is two ways, one is simpler but is more performance costing. Make a list with all game objects in scene with the tag: https://docs.unity3d.com/ScriptReference/GameObject.FindGameObjectsWithTag.html

GameObject.FindGameObjectsWithTag will return a list with all game objects that have the tag you are searching for. This is costing because it will run through all your game objects on the scene. But you can try that to make some tests

The other way, is using a messaging system

https://www.youtube.com/watch?v=k4JlFxPcqlg

This one is a small tutorial that presents the usage of Events for that. But for that you need to understand C# delegates first.

there is also another tutorial that I watched those days, which presents a message system using Scriptable Objects (similar to how the Chop Chop Open Project is doing).

It is a simple way to do that too

https://www.youtube.com/watch?v=lgA8KirhLEU

[magic junco]

Wait wait, you already have them on a list. So you can just run this list on a for / foreach and move them Huaha

[iron kayak]

im currently doing my first unity game ever and i got a problem with a boss

[native token]

does anyone know why onmousedown just stopped working

it was working before and it just stopped

[turbid heart]

does the thing you click on have a collider? @native token

[native token]

yes

it used to work just fine

[turbid heart]

Debug.Log inside your OnMouseDown to see when it gets called

[native token]

i already have one

[turbid heart]

It could be that some other sprite is blocking it

[native token]

it seems it doesnt get called at all

[turbid heart]

Show me the inspector of the object you’re trying to click on

[turbid heart]

Is there anything in front of the sun?

[native token]

nope

i started the game and set every object execpt the one im trying to click to not active and i still cant click it

[turbid heart]

Weird. Have you tried restarting Unity?

[native token]

i should try that

[turbid heart]

Yeah.. i just looked at this https://answers.unity.com/questions/486847/onmousedown-doesnt-work-1.html

[native token]

yea ive seen that too

im gonna make a new object and test it

still nothing

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
public class Sun : MonoBehaviour
{
    public float FallSpeed;
    public int SunValue = 50;
    private float Destination;
    public bool isSpawnByPlant;
    public GameManager gameManager;
    void OnMouseDown()
    {
        Debug.Log("test");
        gameManager.Sun += SunValue;
        Destroy(gameObject);
        
    }

    private void Start()
    {
        gameManager = gameManager = FindObjectOfType<GameManager>();
        if (!isSpawnByPlant)
        {
            GenerateNumber();
        } else
        {
            float tempY = this.gameObject.transform.position.y;
            Destination = tempY -= 0.7f;
        }
            
    }
    void Update()
    {
        if (transform.position.y > Destination)
        {
            transform.position -= new Vector3(0, FallSpeed) * Time.deltaTime;
        }
    }

    void GenerateNumber()
    {
        float destination = Random.Range(-1.75f, 2.4f);
        Destination = destination;
    }

    public void SetDestinationManually(float yPos)
    {
        Destination = yPos;
    }

}

heres the code

everything but the onmousedown works

[turbid heart]

I forgot how it works, but there’s something like an EventSystems object in your scene

[snow willow]

Does the arrow have its own Rigidbody too?

show the object hierarchy

[turbid heart]

There might be somewhere it tells you what you’re hovering or clicking on @native token

[snow willow]

well if you have a script on the arrow that might be moving it

[native token]

the event system is for onpointerdown @turbid heart

its for gui objects

i have one

[turbid heart]

My bad. Can you try making a new empty scene and creating an object with collider and a new script with only an OnMouseDown and debug log in it?

[snow willow]

Click your event system while playing and watch the preview window in the bottom of the inspector

It will show you what the mouse is over etc

[turbid heart]

Oh so it’s not only for ui?

[snow willow]

also make sure you have a PhysicsRaycaster2D on your camera

it is not only for UI

it's for everything

works on colliders too

as long as you have the right kind of raycaster on your camera

and:

• Event System/Input Module

[native token]

oh

should i try using onpointerdown on my prefab instead of onmousedown then?

im looking at the event system preview and it shows nothing when i hover over the object i want to click

when i hover over my other clickable objects they do show up

[turbid heart]

Onpointerdown is for UI i think, so no. Did you check that your camera has the raycaster like Praetor said?

[native token]

yep

it has one

[turbid heart]

Then it’s something wrong with your object alone

Try making a new object and slap on the sun script and a collider

Trying to figure out if it’s your object or script

[snow willow]

OnPointerDown is better than OnMouseDown

it gives you PointerEventData

but it still works basically the same way

• Does your object have a Collider2D?
• Does your camera have PhysicsRaycaster2D?

[native token]

i have both of those

[turbid heart]

My mistake again. I’m on mobile so I’m not as diligent in checking :x

[snow willow]

(you need to implement IPointerDownHandler to use OnpointerDown btw)

[native token]

i know

i have other objects in the scene with it

they are ui objects tho

[snow willow]

SHow the object in question's inspector?

[snow willow]

ok and your camera?

[snow willow]

what is Event Mask set to on the raycaster?

[native token]

it has everything without being set to it

[snow willow]

ok

[native token]

so all the layers are selected

[snow willow]

should work then

🤔

[turbid heart]

Right? This is really bumming for me too

[native token]

its weird because it used to work

it just stopped

[turbid heart]

And it’s just that object?

[native token]

yep

[turbid heart]

Can you try this? #🖼️┃2d-tools message

[native token]

did that

twice now

[turbid heart]

I’m stumped. I’d suggest commenting out everything expect on mouse down in that script and see if it works. Shouldn’t be the issue unless you’re disabling the collider or something..

If you have another script with an on mouse down that works, you could try swapping temporarily

I’ll head to bed now

[snow willow]

the fact that it's not showing anything in the event system preview is telling

maybe a UI element is blocking it? But I would expct that UI element to show up then

so not sure

[native token]

yea im not sure what its doing

im gonna rewrite the script

still nothing

there also are no intersecting colliders

[native token]

im just gonna give up and make it a ui object

all good now

[burnt badge]

im trying to impliment a system where content from one viewport can be dragged into a neighboring viewport and vice-verse. im usinging a pointerEnter and PointerExit to detect which viewport the dragged content is over, so that when the player stops dragging, whichever viewport the content is hovering over becomes a child of the content of that viewport. the only problem is that the pointerEnter and pointerExit event systems consider the content items to be part of the viewport, so when im dragging them away fromt he viewport, it still thinks im hovering over the original viewport

does anyone know how to fix this, or a better solution? i tried using an image that goes over the viewports for my mouse detection, so that way the content items arent a child of that image, but then the image gets in the way of being able to click the content items

[elder minnow]

When a viewport becomes a child, just store that information in a variable, so when you are dragging first you check if whatever you detected on drag first is not that parent

I may have misundertood everything, though

[burnt badge]

i see what your saying! yes i believe that would be a good solution

ill try to impliment that now, thanks wesai

[elder minnow]

No problem, good luck!

[burnt badge]

so i tried that, but a new issue occured. even if the content item isnt a child of the viewport, the fact that im dragging it and its following under my mouse means that it is still getting in the way of the mouseEnter event for the viewports

[elder minnow]

When an object is being dragged it should be ignored then for the events, give it a state

Anyway, I'm having a hard time visualizing all of this and I have to go too

So it's hard to help you there

Good luck, though! Hopefully someone else can come for the rescue

[burnt badge]

np, have a good one

ok, i figured out a solution. i had to add a canvas group component to the content item, then i have it turn "blocks raycast" off while its being dragged, thus allowing me to look under it, then just turn it back on once its placed

[faint glacier]

stupid question: I want to have an object rotate a fixed amount of degrees per second towards something. I've tried every rotation method I could find, but they all either work like a slerp or I don't understand them well enough to implement them. How would I do this?

[snow willow]

Quaternion.RotateTowards(currentRotation, targetRotation, degreesPerSecond * Time.deltaTime);

in Update

[faint glacier]

I think I tried that but it flipped my sprite sideways

i'll try it again and see if it works

[snow willow]

of if it's 2D that won't quite work

[faint glacier]

yeah now it's not turning at all, I assumed it was because I didn't properly convert my vector to a quaternion tho

[snow willow]

You need to use:

transform.right = Vector3.RotateTowards(transform.right, targetDirection, degreesPerSecond * Mathf.Deg2Rad * Time.deltaTime, 0f);```

assuming transform.right is the "forward" direction for your sprite - as people usually do

[faint glacier]

apparently it's not :P

[snow willow]

what is the forward direction for your sprite

[faint glacier]

it looks like it's up, since that makes the code work. Thanks!

[snow willow]

cool

[still tendon]

@snow willow Thanks for help. I got my build done for my match 3 game done.

I am working on a feature that is in line with mother's day.

Would you like to help? I think I'm close.

I have a list of game objects that act as poems.

The object that holds all the poems and should display them has these components.

The current script for PoemKeeper...

https://hatebin.com/bnodljeovd

This debuglog triggers from the PoemKeeper script.

But when I get the gameover screen....

I'm going to try and set a "currentPoem" setting for the script to diagnose it further, but was wondering if you had any idea why it won't play any of the poems I have loaded.

[still tendon]

I'm getting a null reference error, so maybe my script doesn't pull an object like I think it does....

OK, this is probably super easy step.

🤔

Any ideas?

I'm going to try and chance my strategy here.

[formal scarab]

The obvious one is that Findobjectoftype isn’t finding it

[still tendon]

That's true.

I use it for all scripts. I dunno why it isn't working...

[formal scarab]

There's nothing inherently wrong with the code, it depends on how the scene is setup at the time where it runs

[still tendon]

KK.

Let me try from splash. That's where it's supposed to start.

Does this help @formal scarab?

!!!!

@formal scarab I'm so happy!

Thanks so much!

OK, she needs some work.

But I have this setup at game start.

So since tryagainpanel wasn't active until I lost the game, it couldn't find poem keeper.

[formal scarab]

Makes sense!

[still tendon]

My old strategy probably works now. Happy mother's day @formal scarab ! Thanks again.

The line that saved me...

Lookin to make an inventory system and allow for weapon switching. The weapons right now are individual prefabs with an animation which I'm turning on and off under the player hierarchy. Would anyone suggest something different as a more advanced topic?

[storm timber]

use Time.time instead of Time.deltaTime

Time.deltaTime is the interval in seconds from the last frame to the current one

and Time.time is the time in seconds since the start of the application

[tough nimbus]

how do i get a sprite object to snap to the same grid as the tile instead of 'in btween'?

[split lava]

open the sprite editor for that sprite and change where its pivot is

i.e. that little blue circle in the middle

[tough nimbus]

oh, thank you buddy

[split lava]

alternatively, you could simply move your grid gameobject up by 0.5 and to the right by 0.5

depends on what works for your game and your assets

Hello 🙂
Can someone here tell me how to make sprites always fit inside a box with SpriteRenderer? (In UI it works easy with UI.Image and Preserve Aspect Ratio but how do i get this behavior with non UI?)

[turbid heart]

what do you mean fit inside a box? Do you have a picture you can illustrate this with?

[still tendon]

Yes sure, one moment

I Have these Boxes

and I want that the Sprite (Tree, branch) is always Fit inside these Box

How can i achieve this with non UI 😄

[still tendon]

Do you understand? 🙂

[turbid heart]

are you using tiles..? I'm not familiar with that, but hopefully someone else will

[still tendon]

No i am not using tiles, the grid in background is generated by a custom script

and the items are placed on top

i am making a wall bounce but idk how to make it bounce off a wall from bellow left or right all i can do is up my code ```void OnCollisionEnter2D(Collision2D collision)
{
Vector2 reflectedPosition = Vector3.Reflect(transform.right, collision.contacts[0].normal);
rb.velocity = (reflectedPosition).normalized * speed;

    //rb.velocity = Vector2.Reflect(speed,collision.position);
    //rb.rotation += 180;
}```

[shadow matrix]

can someone help me with at problem

[still tendon]

can't you just use a Physics Material 2D for bouncy wall

[lime mulch]

i did not know that i will try it

[elfin wharf]

Can someone give me an idea how to make "transform.position += difference" smooth? It's an enemy class and if enemy gets shoot then it gets knockback. For now at getting shoot it instantly teleports so it looks bad.

[full needle]

I'm trying to get a trigger to switch a boolean from false to true, but the function keeps spitting out errors.
At first I had

    if (collisionInfo.collider.tag == "Player") {
        aggro = true;
        Debug.Log("aggro");
    }
}```
but it told me that `Collider2D` was outdated and I should use `GetComponent<Collider>()` however that gives me the errors `Identifier expected`, `syntax error, ',' expected` and `Tuple must contain at least two elements`

[snow willow]

You've mixed up some code snippet from a OnCollisionEnter2D and one from OnTriggerEnter2D

void OnTriggerEnter2D (Collider2D otherCollider) {
    if (otherCollider.tag == "Player") {
        aggro = true;
        Debug.Log("aggro");
    }
}```

that's all you need

[full needle]

thanks

[fervent otter]

I'm setting my rigidbody2d's velocity.x to zero and my object is still moving very slowly. What am I missing?

[snow willow]

velocity.y maybe? Gravity? something colliding with it? Some code in your script moving it or adding velocity?

[fervent otter]

Uhhh let me type out a good explanation. Bear with me

Its a simple 2d platformer. The main character object has a circle collider on it. The velocity.x is lerp'd toward the max walk speed or zero depending on input. When there is no input the velocity.x gets down to a very small number, but not zero. So I do this if (_velocity.x < minXVelocity && _velocity.x > -minXVelocity) _velocity.x = 0; where minXVelocity is 0.1f.

The reason this becomes a problem is that it makes my player seem to bounce off corners. Imagine the character walks into a short wall and stops. Now I jump, with no X axis input. Because the velocity remains a tiny number the character is pushed slightly over the top corner of this short wall. And because the collider is a circle, when the character falls back down it collides with the corner of the wall and ends up pushing the character away from the wall at a noticeable velocity depending on how fast they were falling.

And I noticed in my Rigidbody2d component that the velocity.x is never actually zero once the player moves at all in either direction.

Despite being explicitly set to zero in the code above.

[snow willow]

i mean the question is when and where are you running this

and when and where are you doing your "lerping"

and how are you lerping

etc..

[fervent otter]

    private void FixedUpdate()
    {
        _velocity = RB.velocity;
        _velocity.x = Mathf.Lerp(_velocity.x, Input.x * maxRunSpeed, 0.25f);
        if (_velocity.x < minXVelocity && _velocity.x > -minXVelocity) _velocity.x = 0;
        _velocity.y += gravity;
        RB.velocity = _velocity;
}

In that clip I'm hitting the wall, stopping, then pressing jump. Idk why my character is bouncing off the top corner

[snow willow]

what is minXVelocity set to?

[fervent otter]

0.1

maxrunspeed is 5

Granted, a very small number, but I'm suspecting this is the cause of the unwanted bounce

The physicsmaterial2d for both the tilemap and character have no bounce

[snow willow]

Can you try setting "sleeping Mode" on your rigidbody to "Never Sleep"

see if that changes anything

[fervent otter]

nope 😦

[snow willow]

🤔

there's no other code that's changing the velocity?

also you haven't modified gravity at all?

and you're sure your ground is 100% flat

silly questions probably but

[fervent otter]

I had the gravity scale set to 2, but even at 1 it does the same thing

If i replace the circlecollider with a boxcollider it doesn't do this

but I want the circle collider so I kind of slide off corners

[snow willow]

Yeah I meant Edit -> Project Settings -> Physics 2D Settings -> Gravity

[fervent otter]

nope, default value

[snow willow]

also do you have rotation frozen?

[fervent otter]

z rot is frozen

[snow willow]

ok good

have you tried a capsule collider?

[fervent otter]

but this is strange -- it only happens on that particular platform and only against the right side of it

[snow willow]

maybe it's the platform then?

[fervent otter]

Its the same tile used for the others, but I'm playing around with it

Nope, does it with other tiles as well

ok so apparently its the composite collider I have on the tilemap

bc removing that fixes it

[plush coyote]

Does anyone know why disabling tilemap colliders take way more time than enabling them? I'm trying to pool chunks, and for some reason loading the collider is almost instant, whereas disabling them takes way longer. It's not my code, as you can recreate this effect by simply disabling and enabling a bunch of tilemap colliders through the inspector

causes huge stutter on disable, but enable is fine

I'm sort of wondering if there is anything I can do internally to unity that would fix this, if its something unnecessary

[mighty meteor]

hlo

[wise nacelle]

@plush coyote What do you mean? You just go into the tile map component in the inspector and turn off the collider2D no?

or did you mean disabling them in a script?

[plush coyote]

both... disabling the collider at all seems to regenerate it and freeze the game for little while if it's even a slightly large tilemap (64x64)

[wise nacelle]

Here, let me show you a 2d game i'm working on and what happens when I turn off the tilemap collider

[plush coyote]

I know what it looks like

im asking if anyone knows why it uses seemingly more resources to disable the collider than it does to enable

the profiler spikes for way longer when disabling than enabling

[wise nacelle]

wrong video oops

is that what you ment?

by turning off the tilemap collider?

[plush coyote]

you dont understand my question in the slightest

but yes

that is what I meant

[wise nacelle]

ah, that I have no idea why

I misunderstood the question

[opaque swan]

can someone help me with this error? playerCollider = GameObject.Find("Laura").GetComponent<BoxCollider2D>(); this is the code that I am using

laura is the name of the player object

[turbid heart]

Either there is no gameobject named Laura in your scene or it doesnt have a BoxCollider2D component

[valid plover]

so how can I check if a gameobject colided with a tilemap with a composite collider(not trigger)

use OnCollisionEnter2d instead of triggerenter?

it kinda works but still super glitchy

[empty garden]

I've gotten buttons to work the other day but I might need help breaking down how im going to accomplish the idea I have in my head.

All of the gameplay and rules is kinda already there. Basically I'm taking a turn based sparring game I do in real life for swords and putting it in unity. But still very lost.

So what i have so far is three buttons that choose three moves. I will need the buttons to change what moves depending on what position the player is in.

[gleaming horizon]

In general yes, OnCollisionEnter2D is the thing, however depending on the behavior you want it can be called pretty frequently based on physics settings and few other factors. What are you trying to achieve?

[valid plover]

i want my bullets to explode when hitting a tilemap wall

[gleaming horizon]

And are these bullets traveling somewhat quickly? If they are you can "miss" the collider based on interpolation settings, timestep and a few other things.

[empty garden]

i think i need to think smaller maybe

[valid plover]

hmm kind off

its kind of working now

[gleaming horizon]

I guess I should really ask what does "glitchy" mean

[empty garden]

im kinda having a hard time getting my ideas into code.

[valid plover]

i got the composite colider geometry to polygons and its working pretty fine now

but with ontrigger enter for some reason

even tho my collider isnt "is trigger"

[gleaming horizon]

Is the collider on your bullet a trigger?

[empty garden]

so if i have buttons that have options 1,2,3 and i want it to display a different set of options like 4,5,6, what would i do

im also having a hard time keeping track of what the player state the player should be in, i have enums that have a list of things but how do i tell the game, this enum is what the player is doing rn.

    {
        windowGuard,
        ironGate
    }``` i want the player to be in on of these two things

[valid plover]

ohhh that might be why xD

[empty garden]

and later on if the player has one of these two guards active the button change depeding on what that guard type is active

[toxic kelp]

            {
                Debug.Log("Has RigidBody");
                FixedJoint2D selffj = gameObject.AddComponent<FixedJoint2D>();
                selffj.connectedBody = collidedrb;
                attached = true;
            }```

idk why but this doesnt attach the fixed joint to any rigidbody

the whole script is supposed to make objects sticky. when it collides with a rigidbody, it makes the fixed joint, but doesnt attach it

[forest portal]

Hi, so I used playerprefs to save my game, it works fine and all but the problem is when you stop compiling and launch it again and press load, it loads your saved score but spawns all the coins back, which can be used to get a big score

[snow willow]

You need to keep track of which coins have been collected already and not spawn them or destroy them.

[forest portal]

how can I do it?

[snow willow]

You're probably reaching the limits of what you can accomplish with PlayerPrefs

make a real saved game system

[forest portal]

no it's so simple

[snow willow]

¯_(ツ)_/¯

then save data about which coins were collected in PLayerPrefs

doesn't matter where you do it but you need to keep track of which coins were collected already

[gleaming horizon]

ehh, this could be a few things unfortunately, if you haven't already make sure you read the script reference for the fixed joint 2d, there are some things that get auto-generated when you create it in editor that don't when directly added as a component. From memory the anchor and some other config options need be set up correctly: https://docs.unity3d.com/Manual/class-FixedJoint2D.html

[valid plover]

how can i make the spawned bullet face where my cursor is? im missing the logic behind it

i have this already ```Vector3 mousePos = Input.mousePosition;
mousePos = Camera.main.ScreenToWorldPoint(mousePos);

    Vector2 direction = new Vector2(
        mousePos.x - transform.position.x, mousePos.y - transform.position.y
        );```

something is making it always face my character xD

so its going backwards

[gleaming horizon]

How are you actually setting the bullet rotation?

[valid plover]

im instanciating it like this Instantiate(bulletPrefab, FirePoint.position, FirePoint.rotation);

this a pretty old project i just picked it up most of the things must be from tutorials lol

[gleaming horizon]

So where does FIrePoint get its rotation? The above code seems to calculate a direction it just isn't used

[valid plover]

the above code i used for my character to turn to where my mouse is pointed

firepoint rotation lemme check that

its not lol, it changed cuz its atached to my character so using the code above it changes the rotation based on my character

[gleaming horizon]

OK, if your character rotation is working alright, and the bullet is always facing backwards you can either: rotate the bullet graphics 180 degrees in the prefab, rotate the bullet around once it's spawned, or just set the axis of your bullet that is the correct orientation to be equal to the direction you calculate, ie: if your bullet is aligned on the x axis you can do bullet.transform.right = direction.normalized. I think this is considered bad practice though, so rotation might be the best bet

[valid plover]

ye as i tought that will only glitch the bullet direction

i'll try to turn the sprite 180, so the actual png

ye that did the trick

[willow current]

How do I make directional particles>

I cant find anything in google or the forums that work

[gleaming horizon]

What do you mean by directional? orienting towards velocity, moving to a certain point, always facing a certain direction?

[willow current]

like, if the character is running to the right, the particles should leave left

i kinda want to do it for all directions, so if the user is jumping to the rght too

like this

[gleaming horizon]

Well, you can do a few things. The simplest is just setting the transform space of the particle system to world, so they will be left behind and look like a trail

you can also just rotate the particle system to face the opposite way the character is moving, so you can have the particles always move "up" but in Update just rotate the particle system so "up" is facing away from the characters velocity vector.

[willow current]

where can i set that?

[gleaming horizon]

are you using the vfx graph or the standard particle component?

[willow current]

Particle System

[gleaming horizon]

OK, so click on it and there should a field called "Simulation Space." Change the dropdown from "local" to "world"

[willow current]

I cant find it

[gleaming horizon]

click on the big thing at the top that says particle system

it should expand

[toxic kelp]

the fixed joint gets created and would work properly if i didnt want it to attach to a rigidbody

its just that the connect body does not get set so it makes the object static.

[gleaming horizon]

And the object your attaching it to also has a rigidbody2d? I think both need one for the connectedbody to work

[opaque swan]

I have no idea what happened but one of my game objects and the sprite just stopped showing

[snow shoal]

how do i set the rotation of my 2d transform by angle?

[snow willow]

transform.rotation = Quaternion.Euler(0, 0, angle);

[snow shoal]

OH of course! Thank you!

[snow willow]

or transform.eulerAngles = new Vector3(0, 0, angle);

[snow shoal]

ok thx so much

[still tendon]

whats the best way to make that detect multiple objects

om using ontrigger enter XD

[toxic kelp]

yes

[toxic kelp]

also, i dont see what you are talking about in the documentation

and i also checked https://docs.unity3d.com/ScriptReference/FixedJoint2D.html

[ruby wigeon]

If i for example want to make one game object render two sprites how would i go about doing that?

Very big beginner here haha

[toxic kelp]

i would make a new sprite and parent it to the other one

might not be the best way tho

[vocal condor]

There's a beginner coding channel but this sounds more like a #💻┃unity-talk question.

[ruby wigeon]

Hmm well im new to unity but ive had experience in other engines, where i could just draw multiple sprites in code, can i not do that here?

[toxic kelp]

nope

[ruby wigeon]

Ah thank you

[toxic kelp]

not that i know of

[ruby wigeon]

No worries thanks for the help :)

[vocal condor]

Add Image components to your object

They're what you're referring to as having an image rendered to the screen.

[ruby wigeon]

Wouldn't that be more of a gui component tho?

[vocal condor]

I wasn't certain what you were targeting.

[ruby wigeon]

So I'd like to make a character, with limbs that i can make look towards the mouse but I'd rather not split them to multiple game objects
Sorry if i wasn't clear earlier

[vocal condor]

Perhaps multiple sprite components https://docs.unity3d.com/ScriptReference/Sprite.html

Not on a workstation and merely giving suggestions from my mobile device

[toxic kelp]

you cant make multiple sprite components

i tried

[toxic kelp]

i think this might be your best bet

[ruby wigeon]

Hmm wouldn't hurt to try, cheers!

[vocal condor]

Consider the multiple object approach

[ruby wigeon]

Yeah I'll most likely have to go with that, although could be a hassle

[vocal condor]

How so?

[toxic kelp]

also i still need this answered. need some hands that stick to objects

[ruby wigeon]

Just drawing up some art to try it out right now

Well multiple characters/enemies that all have multiple objects connected to them would definitely be more costly than just each object drawing its own limbs

[toxic kelp]

i belive there is a way to make "limbs" part of the same object. i dont know how

[ruby wigeon]

Oh well they're purely cosmetic shouldn't affect things too much

Help much appreciated tho

[toxic kelp]

https://learn.unity.com/tutorial/rigging-a-sprite-with-the-2d-animation-package#6017535aedbc2a69ae9b3b9d this might work

[ruby wigeon]

That would work but I've no clue if i can manipulate the rig with code

[toxic kelp]

https://docs.unity3d.com/Manual/class-SpriteAtlas.html there is also this. might work but i dont honestly know what it is

[vocal condor]

What's collided rb? What the current Game Object? Are you a moving limb to be attached to another object? (Just curious)

I'm assuming you're a limb because you've given yourself a fixed joint component

[toxic kelp]

collidedrb is the rigidbody this sprite collides with. the current game object is a hand that is launched and then sticks to surfaces.

here is the script

it creates a fixed joint, just doesnt attach it to the collided rigidbody

@vocal condor

[vocal condor]

Something isn't right about your if statement

rb is assigned null

Rather than evaluating if null

[toxic kelp]

oh crap

thats a common error i make

however, that isnt the problem

@vocal condor its this line:

everything else works

[vocal condor]

Can you attach multiple fixed joints to one object?

[toxic kelp]

yes

[vocal condor]

Else you've already got a fixed joint

[toxic kelp]

im not making a fixed joint for every object

if thats what you're saying

[vocal condor]

Well, in Start you reference and set the fixed joint to not enabled. On collision (assuming the other body has a rigid body component as well and not just a collider) your adding another fixed joint component and connecting it to the other object; looks fine.

So what's the issue (assuming that's the thing - it isn't attaching to the other object)?

[toxic kelp]

yes

it just get attached to "the world"

freezing in place

basically what it looks like

[vocal condor]

Is that the first component or second? (You've got two)

[toxic kelp]

this was the problem

collided rb was null

[vocal condor]

Okay

Sounds like everything should work now (damn Swype - edits)

[toxic kelp]

when i tried to attach the fixed joint

yup it does

[vocal condor]

[toxic kelp]

why did that not cross my mind

would be nice if vs gave you a warning if an if statement is assigning a variable

[vocal condor]

Brain fart moments 🧠 ||💩||

[toxic kelp]

yup

no, it's 🧠 💨

lol

well thanks for the help!

[ebon merlin]

Hey guys..
I am a professional developer who's looking to get into game development now, particularly in 2d and I was wondering if you had any good resources and/or tutorials to recommend to start learning
I'm mainly interested in platformers, but any good resources/tutorials would do, as my main intent is to learn how to properly use unity itself
I've also messed around with shaders and physics systems before, and I've already worked a bit with rendering engines, so I think I could skip the absolute beginner's stuff

TL;DR: What I'm really interested in is a start-to-end (simple) project so that I can get used to the unity flow

[turbid heart]

Describe what you’re trying to achieve and what isnt working as expected. “Why isnt work” doesnt help

Your start is spelled wrong. It’s Start

And use 3 back ticks #💻┃code-beginner message

[turbid heart]

Hit or collider is null. Make sure they’re not null before using them

[wintry plover]

The setup:
Alright, so I'm trying to make a dash triggered by pressing space. The dash should give the player a burst of speed in the direction they are already moving in. I am aware that, this implementation doesn't account for the player gradually slowing down. dashCount is there solely for debug.

The question:
Why does this mechanism register only some dash inputs and ignores others?

The code:

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

public class MovementScript : MonoBehaviour
{
    public Rigidbody2D body;
    public float speed = 20.0f;
    float horizontal;
    float vertical;
    
    public float dashMult = 10.0f;
    bool dash;
    int dashCount = 0;
    
    void Update()
    {
        horizontal = Input.GetAxisRaw("Horizontal");
        vertical = Input.GetAxisRaw("Vertical");
        dash = Input.GetKeyDown("space");
    }
    private void FixedUpdate(){
        if(dash){
            Debug.Log("Dash" + dashCount);
            dashCount++;
        } 
        body.velocity = new Vector2(horizontal, vertical) * speed * (dash?dashMult:1);
        dash = false;
    }
}

[vocal condor]

Why does this mechanism register only some dash inputs and ignores others?
What do you mean by this? Give an example.

[wintry plover]

If I press space it sometimes works and sometimes doesn't.

It's not a keyboard thing since I can write here just fine.

[vocal condor]

How are you determining that it's working (how are you verifying)?

[wintry plover]

By watching the console

[vocal condor]

If you tap every few seconds, does it continue to log?

[wintry plover]

and watching the game

What do you mean by continue?

[vocal condor]

Not working as in not speeding up or not logging?

[wintry plover]

neither

[vocal condor]

It should be working; the input detection for "space".

The code looks fine.

Problem may lie elsewhere.

[wintry plover]

The gameobject with the script is just a standard white square with a rigidbody2D

[vocal condor]

Not relevant. The above would trigger a log of dash and dash counts every time "space" was pressed with the exception of there being fewer physics frame than logic frames.

[wintry plover]

Hold on, I could technically increase dash count in Update and print in FixedUpdate, that way I'd see if it was really skipping some

[vocal condor]

If you have fewer physics frame than logic frames, it could possibly assign dash to false again before the physics frame has occurred making it look like dash failed.

[wintry plover]

How do I check if I have fewer physics frames than logic frames?

[vocal condor]

Or possibly: ```cs
if(!dash)
dash = Input.GetKeyDown("space");

Assuming that your game is running at 60 fps, it would likely be true; we've got way more computational power than such.

With the above code, your dash will only be set to false in the physics frame.

ie FixedUpdate.

Or you could do: ```cs
if(Input.GetKeyDown("space"))
dash = true;

[wintry plover]

I did just did that, it works

[vocal condor]

Whereas assigning it to the result of input would allow it to be true or false so if you explicitly need the input to be evaluated... okay

[wintry plover]

interesting

[wintry plover]

Thank you, but I still don't understand what you meant by this

[vocal condor]

It depends on the behavior you intend for it to produce.

Since (in your case) you're wanting it to evaluate/count every pressed of space and only reset dash to false in the physics frame, you likely explicitly do not want to allow Update (the logic frame) to be able to reset dash.

[wintry plover]

oh, I get it now I think

right

thank you so much

[bronze sundial]

so im making a 2d unity game, and i have my code setup for calculating when my player takes enough damage to die, and my animation is ready, but i want a way so that during the animation, no keys (inputs) can be pressed. any way to go about that without adding a condition to all the if statements that check for inputs?

i can use (this.animator.GetCurrentAnimatorStateInfo(0).IsName("playerDeath")) for the if statement, im just not sure how to go about turning off all inputs

[turbid heart]

By using a boolean

[bronze sundial]

well i know that i can add conditions with a bool to all my movement if statements, but i was wondering if theres a function like (TakeNoInputs) or something that i can use with a WaitForSeconds so the death animation could play then you can go back to menu screen

just to save me some time, also because this is how my movement works and i have no idea how to shove this into an if statement // Moves sprite left and right Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), 0f, 0f); transform.position += movement * Time.deltaTime * moveSpeed; moveDirection = Input.GetAxis("Horizontal"); // Makes "Speed" an absolute number, easier for the Animator when creating movement sprite animator.SetFloat("Speed", Mathf.Abs(moveDirection));

[turbid heart]

that's the easy part. just wrap it in an if statement saying if(canMove) or something

[bronze sundial]

wow, i never thought of that. LMAO, i guess that makes alot more sense

so im guessin that theres no such thing as a TakeNoInputs function or somethin'?

[turbid heart]

not that I know of.. feel free to google that yourself though

[carmine stag]

yeah, and the jump animation is messed up

[full oriole]

For your jump animation, are you using a trigger?

within the animator i mean

So once its done executing it goes back to the idle state

[carmine stag]

it's a bool

[full oriole]

In your animator set up a trigger

and in your code when you press space

call that trigger

[carmine stag]

can you send a code example? I don't know what you mean

[full oriole]

erm let me see if i have a project

I just cleaned my unity hub 😂

[carmine stag]

ok

[full oriole]

ok this might look a little bit confusing

i only have an example of an attack

so inside the animator
