@desert swallow

[desert swallow]

are you changing your text in update?

[still tendon]

uhh

sort of

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.CompareTag("Player"))
        {
            _inRangeNpc = true;
        }
        else
        {
            _inRangeNpc = false;
        }
    }
    private void Update()
    {
        if (_inRangeNpc == true)
        {
            if (Input.GetKeyDown(KeyCode.E))
            {
                _dialogue.StartWriteTextCoroutine();
            }
        }
    }

this is in update

but

the method itself

and other methods

arent\

        public void StartWriteTextCoroutine()
        {
            StartCoroutine(WriteText(input, textHolder, textColor, textFont, delay, sound, delayBetweenLines));
        }

    public class DialogueBaseClass : MonoBehaviour
    {
        public bool finished { get; private set; }

        protected IEnumerator WriteText(string input, Text textHolder, Color textColor, Font textFont, float delay, AudioClip sound, float delayBetweenLines)
        {
            textHolder.color = textColor;
            textHolder.font = textFont;

            for (int i = 0; i < input.Length; i++)
            {
                textHolder.text += input[i];
                SoundManager.instance.PlaySound(sound);
                yield return new WaitForSeconds(delay);
            }

            yield return new WaitForSeconds(delayBetweenLines);
            yield return new WaitUntil(() => Input.GetMouseButton(0));
            finished = true;
        }
    }

[desert swallow]

it'll only write the text when you press E. you have to be focussed on the game view for it to detect keypresses

[still tendon]

well lol

the functionality works

look at the right side

notice how it actually writes, without showing up

[rose prawn]

ah i see, onMouseDown needs a box collider

we are making progress here...

[desert swallow]

getting there 😄

[still tendon]

i had the mouse down commented at one point

doesnt make a difference

[rose prawn]

https://www.youtube.com/watch?v=c69oZprM1oc&ab_channel=Unity'

dunno, i just found this.

[still tendon]

its.

not

even

related

[rose prawn]

very much it is, to my problem atleast

[still tendon]

oookay bro

    public class DialogueBaseClass : MonoBehaviour
    {
        public bool finished { get; private set; }

        protected IEnumerator WriteText(string input, Text textHolder, Color textColor, Font textFont, float delay, AudioClip sound, float delayBetweenLines)
        {
            textHolder.color = textColor;
            textHolder.font = textFont;

            for (int i = 0; i < input.Length; i++)
            {
                textHolder.text += input[i];
                SoundManager.instance.PlaySound(sound);
                yield return new WaitForSeconds(delay);
            }

            //yield return new WaitForSeconds(delayBetweenLines);
            //yield return new WaitUntil(() => Input.GetMouseButton(0));
            finished = true;
        }
    }

how much is it related now?

[desert swallow]

@still tendon realise that you're not the only one in this chat please

[still tendon]

well, after i got ignored 3 times in different chats, i have realized that, thank you very much

[desert swallow]

Manners go a long way

[still tendon]

exactly, manners

[desert swallow]

Consider being patient and polite. Also word your questions better and please for the love of god don't send one word messages in succession. You're making it really hard for me to want to help you

[still tendon]

#💻┃code-beginner message

#💻┃code-beginner message

i already did ask the question two times

[desert swallow]

And how much research did you do on your own outside of asking twice?

[rose prawn]

so, they do move now with rigidbody and onMouseDown, but on mouse down breaks the functionality so that they teleport upwards and instead of following my mouse

[still tendon]

the only research i found

was that i need to use textmeshpro instead

[desert swallow]

show your code

[desert swallow]

and how's that going for you

[still tendon]

im not going to switch the whole text method because some person told me that its better to use, when unity methods already suffice

besides, that would lead to more research, because textmeshpro is more for hd not pixel games

[desert swallow]

Untrue, TMP has much more functionality. You can use it wherever

[rose prawn]

sure thing

 using System.Collections.Generic;
 using UnityEngine;
 
 public class DragY : MonoBehaviour
 {
     Vector3 first, second;
     public float speed = 15;
 
     void Update()
     {
         void onMouseDown(){
         if (Input.GetMouseButtonDown(0))
         {
             first = Camera.main.ScreenToViewportPoint(new Vector3(0, Input.mousePosition.y, 0));
         }
 
         if (Input.GetMouseButton(0))
         {
             second = Camera.main.ScreenToViewportPoint(new Vector3(0, Input.mousePosition.y, 0));
             Vector3 diff = second - first;
             transform.position += diff * speed;
             first = second;
         }
         }
     }
 }```

i also tried a more reduced version where there was only onMouseDown without any  of those class object variables. and inside onmousedown i had put the latter if clause

[still tendon]

im done

[desert swallow]

Your onmousedown function is inside your update, I don't know if that's intended

I'm more amazed that it'd even compile like that

@rose prawn also you have to strictly follow the case of the function in order for Unity to recognise it as one of its events

OnMouseDown()

[rose prawn]

i did that after my first try. the functionality remains the same.

you see, i'm a java programmer and during these two days our programming teacher set up a game jam for those who were interested.

thing is, i (we) have been thrown into unity and C# just under 24 hours or so and none of us knows any unity or C# syntax. so this is more like googling 101 for all of us

an experiment of sorts if you will

[desert swallow]

The class structure in java and c# is pretty much the same

[rose prawn]

yeah, i know that much

it's more like i don't know what any of the methods or what do they do. the logic just isn't there even if i know the somewhat similiar syntax

[desert swallow]

https://hatebin.com/wjjqfgjzyv

[rose prawn]

wait

[desert swallow]

That assumes that you haven't moved your camera and it's still at 0,0,-10

[rose prawn]

let me read thru that

yeah, the camera doesn't move

[desert swallow]

https://hatebin.com/ysjiqatkdr edited it, didn't realise I had done it a little wrong

@rose prawn here's a complete list of the unity event functions, under the Messages category https://docs.unity3d.com/ScriptReference/MonoBehaviour.html

[rose prawn]

thanks a ton, but there one itzy bitzy thing.

[desert swallow]

Also that code will allow you to drag in both x and y, not just y

[rose prawn]

we are recreating this

[desert swallow]

ah okay

[rose prawn]

so it's essential you must be able to move it only x or y

[desert swallow]

https://hatebin.com/pyycqzvozs

I just added line 12

[rose prawn]

beautiful, now let me read and try to understand it

just a sec

onmousedown and onmouseup are implementable methods?

[desert swallow]

They're listed in the doc I sent you

[rose prawn]

aight

will look into it

oh my this is bloody beautiful

thank you

i know where to go from here. you are amazing :3

[desert swallow]

🥳

[hearty anvil]

I've got everything set now

Idk if it's improved anything though

Falls below 60 FPS at around 300 bullets

[desert swallow]

What's your bullet object look like?

[hearty anvil]

Like the actual sprite or

[desert swallow]

No like what scripts does it have on it

[hearty anvil]

https://pastebin.com/Zh3RPxmL

This

https://pastebin.com/b6PnUD9C

And this

Along with a RigidBody2D and CircleCollider2D

[desert swallow]

It doesn't look terribly demanding

As a rule of thumb, GameObject.Find() is pretty slow, so if you're doing that 1000 times it'd be noticeable, however you only do it once per object so it shouldn't be an issue once it's assigned

also you can see the fps in the stats menu at the top right of the game view

just to make sure it's not your FPS code that's giving a wrong number

do you need to be doing animator.SetInteger("setColour", bulletColour) every frame?

@hearty anvil

[hearty anvil]

Hmmm my FPS code is actually giving me an incorrect number

Interesting

The real number is in fact higher

Phew

Panic over

Ohhhh thank God

Okay so I realised having over 1000 bullets may be too much for Unity, at least with my current level of optimising

So I decided I'll have a universal max of 600

Seems like the game can handle that fine at an average of about 110 fps

Still, I want to add more things to the game such as possible blending effects on the bullets as well as some particle effects for explosions and all that stuff. That and a working background. Does that sound feasible to do without falling below 60fps?

Oh by the way is there a way I can access the variables of the enemy bullet component so I can like set the speed when I activate one?

[desert swallow]

make them public

[rose prawn]

my objects collide correctly and they stay within the boundaries...

but only when pushed by another object

using a mouse they will go over the designated area

somewhere on the interwebs someone said something about moving them by velocity and not by mouse

also, why do they jiggle when pushed against a wall? it doesn't really matter since in the end you are not supposed to be able to push them with other ducks

[orchid pewter]

when calculating velocity for movement do you do it based on frames per second?

for example if you've got 6 frames for walking and 8 frames for jumping then walking should be slower?

[rose prawn]

srsly dunno

[rose prawn]

seee here

[hearty chasm]

it breaks after spawning about 8 objects (40 beats into the game). It seems fine every time before that tho

[tropic charm]

I don't see how the code you posted would cause the problem you describe. The problem is likely elsewhere.

[rose prawn]

i got it fixed

but now there's a new problem

if i move it with enough speed, the collider ignores it

all i had to do was transform it, not by the location of the mouse, but the speed that comes with it

oh and also this brings back the previous problem where multiple objects are moved at once

[rough gorge]

Cinemachine + URP + Unity 2d + Pixelart + Cinemachine pixelperfect = Jittering sprites while moving camera. Any solution?

[deft charm]

try to set Interpolate to "interpolate" on rigidbody

[chrome anchor]

so I am trying to create a separate dash action script for the player (i want enemies to use this ability too so i split them) and i don't understand game objects very well.

How do I make it so the dash script gets code from the player script (x and y movement) and modifies the player's movement accordingly (to make the player dash)?

[tropic charm]

What you want to do can be accomplished a couple of ways. 1) The Player script and the Enemy script can derive from the same base class--MoveableCharacter, for example. The Dash script can then get a reference (in Start(), for example) by using GetComponent<MoveableCharacter>(). 2) You can use scriptable objects. I suggest you use the free ScriptableObject-Architecture asset on the asset store for this. If you use scriptable objects then the Dash script will not need to know about the Player script or the Enemy script. It can get access to the necessary information through scriptable object fields.

Example use of scritable object fields...

    [SerializeField] private FloatReference _playerMaxHealth;
    [SerializeField] private FloatReference _playerCurrentHealth;

[chrome anchor]

I see, thank you

[chrome anchor]

are there any tutorial videos on using scriptableobject-architecture?

[tropic charm]

Yes, that particular asset was inspired by some Unity conference talks. https://youtu.be/raQ3iHhE_Kk https://youtu.be/6vmRwLYWNRo

There is also documentation on the project's github page.

[chrome anchor]

oh cool

[chrome anchor]

it doesn't recognize floatreference

[tropic charm]

using ScriptableObjectArchitecture;

[chrome anchor]

oh, thanks!

[grizzled burrow]

Hello! I'm new to unity, and want to get to experience c#. Is there some articles you guys recommend?

[tropic charm]

I think these are what most people are recommending these days. https://learn.unity.com/project/beginner-gameplay-scripting

[remote moth]

How to can i save and load a object with all parents objects?

[silver heron]

by creating the parent object with sub objects all attached? otherwise if your talking about setting flags would have to save them somewhere then load them

[mellow owl]

Hi, im having a problem with OnCollisionEnter2D, theres already 2d colliders on both of the objects but the function wont get called, any suggestions? Thank you

[grizzled burrow]

Okayz thank you

[earnest wind]

How can i make it so that when the red box collides with the white one the white box gains a certain amount of impulse?

[mellow owl]

@earnest wind Im a noob but maybe use OnCollisionEnter2D and then add force in the opposite direction?

[earnest wind]

That's what i have done

[desert swallow]

What is happening instead?

[earnest wind]

But it doesnt work

[desert swallow]

You're asking for 2 frame perfect events there

The exact frame that they collide, and the exact frame that space is pressed

If you want to check if they press space while they continue to collide, then use OnCollisionStay2D instead

Otherwise if you want to check if they're holding space at the point of collision, use Input.GetKey(KeyCode.Space)

[earnest wind]

Yeah that was the thing

Also how could i do so that it gets impulse depending from where the red box is?

Like, if the red box collides with the white box in the right side the white box gets impulse to the left

[desert swallow]

instead of new Vector2(0,5) you can do something like redbox.transform.position - whitebox.transform.position which would give you a direction pointing from the center of the red box to the center of the white box. You could then multiply that by whatever force you want

[earnest wind]

Doesn't work

[desert swallow]

What does it do instead

[earnest wind]

It doesn't do anything at all

Also, i guess if i have the red box and the with box in diferent scripts i need to instantiate one of the right?

[desert swallow]

void OnCollisionStay2D(Collision2D collision)
{
  Vector3 dir = collision.transform.position - transform.position;
  if(Input.GetKeyDown(KeyCode.Space) * collision.gameObject.CompareTag("Cid"))
    rb_caja.AddForce(dir.normalized * 5.0f, ForceMode2D.Impulse);
}

Assuming this script is on the white box, you can get the red box from the collision parameter

[earnest wind]

Oh gotcha

It works but instead of going the opposite direction it goes in the same direction as the red box

[desert swallow]

oh, flip the values around then

[orchid pewter]

is it possible to detect what type of tile the raycasting is looking at?

[desert swallow]

transform.position - collision.transform.position

[earnest wind]

Ok i got it

Thanks for the help 👍

[marble badger]

What should the output be and why

[timid kettle]

hey guys, I have this Tile Map with a composite collider component on it, how can I get all the platforms positions (I want to dynamically spawn monsters on them) ?

[orchid pewter]

how do i randomize between -1 and 1?

one or the other

[still tendon]

Hi, I'm trying to deal damage to a new enemy that I have created but I cannot because I have made a new script for him.

private void DealDamage()
    {
        Collider2D[] enemiesToDamage = Physics2D.OverlapCircleAll(AttackPosPlayer.position, AttackRange, WhatisEnemies); Debug.Log("DealDamage Initiated");
        for (int i = 0; i < enemiesToDamage.Length; i++)
        {
            enemiesToDamage[i].GetComponent<Enemy>().TakeDamage(dealsDamage); Debug.Log("Dealt Damage to Enemy: " + enemiesToDamage[i]);
        }
    }```

This is the script for the player

If i want to deal damage to, lets say a few enemies should i add them too in the loop where enemiesToDamage[i].GetComponent<Enemy>().TakeDamage(dealsDamage); Debug.Log("Dealt Damage to Enemy: " + enemiesToDamage[i]); is

The script for first enemy is "Enemy" and second is "EnemyGhost"

or can i somehow have the player identify which script is on the enemy

[still tendon]

Fixed it myself

I'll post it here just if anyone wanted something similiar

You can use if(enemiesToDamage[i].name.contains("Keyword"))

[tropic charm]

Use Random.value or Random.Range() as follows.

float f1 = (Random.value < 0.5f) ? -1.0f : 1.0f;
int i1 = (Random.value < 0.5f) ? -1 : 1;

float f2 = (Random.Range(0, 2) == 0) ? -1.0f : 1.0f;
int i2 = (Random.Range(0, 2) == 0) ? -1 : 1;

Debug.Log($"f1 = {f1}  i1 = {i1}");
Debug.Log($"f2 = {f2}  i2 = {i2}");

[orchid pewter]

what does ? -1 : 1; mean?

Hi! I'm making a game an easy 2D game that moves jump and do other stuff (not yet in the code), but I have an issue, when I code the mode everything is fine, but whenever I enable the Animator (so it looks better) I can't move on the X axis neither on the Y axis, I struggled all day yesterday with that and still cannot find a solution so I'll be very thankful if someone can help me with that, my code looks like this:

[formal lava]

I know this is for code but could someone help me. whenever i move it like paints itself behind the actual sprite

im new btw

[peak stirrup]

I'm using a tileset collider 2d on the ground and a box collider 2d on the player but the player randomly gets caught on the platform and stops moving, does anyone know how to stop this from happeneing?

[tropic charm]

1. Try using a composite collider 2d on your tilemap and/or 2) Try using a capsule collider 2d on your character.

https://youtu.be/SW6tpzF7I60

That video will show you how to setup a composite collider on your tilemap.

[peak stirrup]

thank you

I don't want to use a capsule colider because if you get too close to the edge you end up sliding off

It worked! thanks for the help @tropic charm

[formal lava]

is there a easier way to make your tiles have a collider other then making a colider

or like how do you make a collider for a slope

[tropic charm]

@formal lava Usually the collider that unity generates based on the sprite works fine.

Just make sure the tile's Collider Type is set to Sprite.

[formal lava]

ok thanks

[tropic charm]

See this also in case you want to change the default. https://stackoverflow.com/questions/58707598/how-to-change-collider-in-individual-tile-in-tilemap

[formal lava]

how do i fix this

where the sprites are very tiny

[formal lava]

where is the pixels per unit couse i dont see it when i click on the sprite

[crisp flume]

click the sprite in the explorer or whatever it's called, then check the inspector and it should be there

[formal lava]

are these blue lines part of the sprite or just camer/scene

[tropic charm]

@formal lava That might be tile bleed. It's a big pain to deal with.

[chrome anchor]

this function only works when the game starts but not when i update the health value. am i supposed to call the function somewhere?

[desert swallow]

@chrome anchor are you familiar with events?

[chrome anchor]

not really, i did make a game event listener though

[desert swallow]

You would call HealthChanged whenever you actually change the health, e.g. TakeDamage() or Attack()

[chrome anchor]

https://github.com/DanielEverland/ScriptableObject-Architecture/wiki/Quick-Start
this tutorial says it's supposed to update by itself (i use scriptableobject-architecture)

[chrome anchor]

yeah i did that part here

[tropic charm]

What you have looks similar to what I had when I went through that same example and I didn't have a problem. Obviously, you have to change the value of that variable at some point...

[still tendon]

how do I change the collider of a tile from a tile map

[tropic charm]

_playerCurrentHealth.Value -= 1;

[chrome anchor]

hm

[tropic charm]

#🖼️┃2d-tools message

[chrome anchor]

I think it's just the slider having issues. I ran a command that drained my hp every frame and it worked

Thank you for your time though

[tropic charm]

So you were changing it in the inspector? I just tried to change it in the inspector too and it didn't call the event. So that sounds like a bug since that's exactly what he is doing in the example.

[chrome anchor]

Yep, that was the case for me

[tropic charm]

Someone has a 29-day old pull request for it. https://github.com/DanielEverland/ScriptableObject-Architecture/issues/141

It wasn't an accident, though. It is pretty obvious that it was intentionally pulled out.

[formal lava]

is there any way t recover an unsaved file

[still tendon]

theres tilemaps in my main camera object. Are these supposed to be here

@formal lava yes idk how but you can

[tropic charm]

Which editor are you using? Some are smart enough to do that.

[formal lava]

no my entire gaddamn unity game

[tropic charm]

Unless it is in the OS's Recycle Bin then it is likely gone. Although, a "unity game" is several files so you would have had to lose the entire folder.

[formal lava]

well the thing just crashed

[still tendon]

anyone know?

[formal lava]

all my files seem to be here just all trhe charecters and shit is off the screen

and delted fronm the hierachy

[tropic charm]

No, there shouldn't be a tilemap on your camera.

[formal lava]

i think ill be good all my scripts are still here

[scarlet violet]

source control

[still tendon]

Black lines keep coming up in my game. Is it a rendering issue? Do you need a video?

[orchid pewter]

do you think this is okay? being able to be a few pixels over before falling

[tropic charm]

You're doing a tile map, right? The problem is likely tile bleed.

[tropic charm]

Users will likely be annoyed by that.

[orchid pewter]

not sure what i could do

[scarlet violet]

I always err on the side of making the box collider a bit smaller, rather than larger. Nothing more annoying than getting hit by projectiles when the player feels like it wasn't even on them.

[orchid pewter]

i understand but i don't like pixels clipping through stuff

[scarlet violet]

Why not try a polygon? @orchid pewter

[orchid pewter]

i don't know i am learning

[scarlet violet]

Ok, just a thought.

I'm learning too.

[orchid pewter]

i guess its fine for now hehe

[scarlet violet]

Hint: There are other colliders rather than just the box.

[orchid pewter]

i'll make a note of it for future

[scarlet violet]

Sounds good.

I think it's fine for now too 🙂

[orchid pewter]

all the tutorials use box colliders lol

[scarlet violet]

Sure, but you don't have to, it's your project.

[orchid pewter]

i know

[scarlet violet]

What if you want to change something else but the tutorial doesn't?

You might be screwed, or could be great. Worth exploring.

[orchid pewter]

i already do that within limits

[scarlet violet]

You might want to try:
https://docs.unity3d.com/Manual/class-PolygonCollider2D.html

[orchid pewter]

yeah i thought the alternative would be messy hehe

maybe i could work around it with new pixel art

[still tendon]

how do I make my animation slower so the players not on gfuel

[orchid pewter]

@still tendon in the animation tab click the three little dots top right corner, then enable Show Sample Rate, i change 60 to 12 or 10 and it'll space the animations apart

[still tendon]

Thanks!

[still tendon]

how do I delete a transition

[orchid pewter]

select it and click delete?

[formal lava]

why is it able to see the like icon of the light

[tropic charm]

That's a gizmo. Click the left-hand side of the 'Gizmos' button (not the arrow) to enable/disable them.

[rotund remnant]

Anyone know a way to "stick" an object to a 2D animation? Like put a separate sprite over the moving character's foot for a shoe. I know I can maybe lerp it to match the animation, I just dont know if anyone has done something like this before. These will be different items that will change

[snow willow]

Put your shoe as a child of a transform that is being animated

[rotund remnant]

Its just a sprite sheet, so there really isnt a transform for that 😦 I think the only way is to do it through movement within script to match the animation speed

[snow willow]

If it's a Sprite sheet then it's not straightforward

But you can always add an empty transform to your animation clip

And just match up the keyframes to the sprite manually

No script required for that

[rotund remnant]

Ah I didnt know you could do that, ill take a look!

Thank you

why unity show my image so:

[silk pendant]

Hi all, I'm starting in the game development world now but I already have a good experience in C#.

Do you guys have any starting point to share with me? I'm studying random things in the unity 2D engine but should be better if someone give me some ideas on how to start with it or something like that.

Thanks a lot 😃

[lean estuary]

@silk pendant It is still advisable to go through the course like "Create with Code" (pinned in #💻┃code-beginner ) to familiarize yourself with engine itself in a more methodical way.

[silk pendant]

Thanks a lot buddy. I'll take a look on it.

[sick pier]

Hi im a beginner unity user who has used Godot for a year now but i want to use the firebase capabilities of unity and I was wondering if there was a way to save a gameobject as a file and then place it into multiple scenes

for ex: a player who is need in multiple level scenes

[compact moat]

i think you can just drag it to the project window

[lean estuary]

You can keep runtime data in ScriptableObjects, which when used as assets can be referenced from multiple scenes. Or offload data to Json on exit if you need persistence between runs.

if i've got 16 pixels per unit how do i jump one unit with velocity?

i've read conflicting help like if i wanted to jump 100 pixels it would be 100 / 16 = velocity but that doesn't work unless i'm doing something wrong

[dense flame]

One unit is one unit, you don’t need to calculate using the pixels per unity if you are setting them properly

[orchid pewter]

so one velocity should equal one unit then?

[dense flame]

I’m not sure, but I think velocity is in units per second

The physics velocity

[orchid pewter]

so i should travel one unit every second?

[dense flame]

I think it will

[orchid pewter]

just tried it and i only moved about one pixel

per second or 1/16th a unit

[dense flame]

16 pixels per unit means each unit has 16 pixels

Not that one unit is the size of a pixel

Check your import settings of the sprite

[orchid pewter]

one unit is 16 pixels

so if velocity is 1 then i should move 16 pixels per second?

Unity velocity is in units/s. To convert those units, it solely depends on the scale you created your game in. If you let 1 unity unit = 1 meter for all your objects when you create them, then velocity is meters/s. For 2D, the default pixels per unit is 100, so if your velocity is 1, that would be 100 pixels/s.

when i make velocity 1 i'm not moving one unit per second

rb.velocity = new Vector2(1f, rb.velocity.y);

wait maybe it does 😮

maybe its the gravity of jumping that is messing things up with my maths

seems perfect when walking

[dense flame]

Friction and gravity may affect the velocity

Check on the Rigidbody info to see that velocity is exactly 1

[orchid pewter]

yeah i need to calculate my jump to include gravity

just need to figure out how to jump one unit a second if gravity is 9.8

[desert swallow]

Well you'll never move upwards at a constant velocity as gravity is accelerating you in the other direction

What's your end goal?

[orchid pewter]

just wanna figure out how to change my jump height for puzzle platforming

[desert swallow]

https://www.youtube.com/watch?v=PlT44xr0iW0

[orchid pewter]

i wanna see what is possible with jumps

by calculating the jump height accurately

[desert swallow]

^ That video has what you're looking for

[orchid pewter]

thanks

[dense flame]

Change the velocity until the height is like you want

[orchid pewter]

that is one method yes

[desert swallow]

The video I posted uses kinematic equations to specify the max Y position of a jump and allows you to determine the exact velocity needed for it

[dense flame]

Wow, that’s very cool

[desert swallow]

Mathematics ™️

[dense flame]

I’ll add it to my playlist

[desert swallow]

I'd sub to the guy, he's been invaluable to my learning

[scarlet violet]

How did you fix? @forest hedge

[forest hedge]

completly re-did my code after following a tutorial lol

so not really fixed

just scrapped and redid

[scarlet violet]

Ah ok was just curious if there was something specific you put in.

[brisk badge]

How do I make sprites (using 2D URP) cast and receive shadows? I've looked online, but the only posts I've found are for 2D games in a 3D project

[hollow crown]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@10.3/manual/2DShadows.html

you need to be using the 2D Renderer and 2D lights

[brisk badge]

I am using the 2D renderer and lights, but that doesn't seem to work either

[inner ferry]

Hi everyone. I've often seen people say that transform.Translate is worse than rigidbody.velocity, because it doesn't work well with collisions. But when I turned on Auto Sync Transforms the collision started working perfectly. And since the vectors are not involved, transform is also easier to change. Well, the question is: is rigidbody better than transform, and in what way?

[wooden gust]

I was using the unity tutorials but they are using an older version is there any tutorials with the current version

[dense flame]

Tutorials in unity 2018 and 2019 should work fine, it hasn’t changed so much

Unless it is a specific feature that had huge changes, what tutorials are you searching for?

[wooden gust]

They show the tile section and the newer version didnt have it

[dense flame]

Which title section?

Ahh, tile

On which part?

What do you mean, where is it supposed to be?

In unity 2020.2 you go create>2D>tile

For tilemap you right click on the hierarchy 2D>tilemap>rectangular

[wooden gust]

I dont have tile

[dense flame]

On where?

[wooden gust]

create 2d

[dense flame]

Which version of unity are you using? Is it a 2D project?

[wooden gust]

2.2.7 and I though I did

[dense flame]

You mean 2020.2.7?

[wooden gust]

yea, sorry

[dense flame]

On the top part go to window>package manager>in project and check it has 2d Tilemap installed

[wooden gust]

I do

[dense flame]

Hierarchy: Create>2D> tilemap appears?

[wooden gust]

I do have that

[dense flame]

Go to window>2D>tile palette

[wooden gust]

yea that works

[dense flame]

Then create a tile palette

And drag a sprite

[wooden gust]

Doesnt all me to create new

allow

[dense flame]

Why?

[wooden gust]

Some how there is something already in there

[dense flame]

Show me a screenshot

[dense flame]

Then there are the tiles already created, what is the problem?

Do you want to add more?

[wooden gust]

And were that come from?

I didnt make it

[dense flame]

Is that a downloaded project?

[wooden gust]

yea, but I started new and just download the assets

is that right?

[wooden gust]

I problem is they took out tile in the newest verision

[peak cargo]

Does anyone know the math I’d need to make a UI sprite that hovers over the mouse on one canvas also work the same for another display of a different size? None of the ways I’ve tried so far have kept it to the same ratio, like if display 2 is half the size of display 1 the icon on display 2 isn’t at 1/4 across when it’s 1/4 across on display 1

[flint vortex]

Hi, how can i set the main camera to stop when reaching the tilemap edges?

[strong sand]

I'm using Vector2.MoveTowards to make a sprite move/follow another, how do I figure out if the sprite is moving left, right, up or down?

[snow willow]

I'm not sure how these two things are related

are you trying to figure out if you're moving left/right/up/ or down, or are you trying to find the nearest object?

[strong sand]

My bad, got it solved tho. Tried to find out the direction of where my object was moving.

[snow willow]

alright

[strong sand]

https://i.imgur.com/9ncAVQh.png

public ParticleSystem psBlood;
Instantiate(psBlood, target.GetComponent<Transform>());

How come this doesn't instantiate it?

(not even in the editor)

Not getting any errors

[hollow crown]

you're sure the code is running?

[strong sand]

Yeah

            if(enemy.getHealth() <= 0)
            {
                ParticleSystem ps = Instantiate(psBlood, target.GetComponent<Transform>());
                ps.Play();
                GameObject.Destroy(target);
                target = null;
            }

The object gets destroyed properly after

Tried the play part since it didn't work at first but then noticed it wasn't even spawned in the editor

[hollow crown]

but you just... destroy the object

[strong sand]

Yes, the target. Not the particle system?

[hollow crown]

you instance it and immediately destroy it because it's the child of what you destroy

[strong sand]

How do I spawn it on that position without parenting?

[snow willow]

You're basically saying "Here hold this baby", and then throwing the person and the baby off the cliff together

        {
            rb.velocity = new Vector2(MovementSpeed, 0f);
        }``` it says "Assets\Scripts\Controller.cs(23,13): error CS0029: Cannot implicitly convert type 'float' to 'bool'", on the if statement

[hollow crown]

if (Input.GetAxis("Horizontal"))

what does that mean

[quick oxide]

it gets "W A S D", and the keys

[snow willow]

Sure, and returns them as a float

E.g -1 to 1

[quick oxide]

oh, how do I fix that?

[snow willow]

You ever try to write if (-1)?

Depends on what you want to do

Probably compare that value to something

Why is my layerMask not working (wrt to Raycasts). I'm using it to detect if the player is in the line of sight of the enemy, but the raycast is colliding with the enemy even though the enemy's layer (default) is not included in the layerMask ```cs

{
RaycastHit2D hit = Physics2D.Raycast(body1.position, body2.position, layerMask);

    if (hit.collider == null)

I've gotten quite confused, I have one script trying to import basic pathfinding. That script has this variable: https://i.imgur.com/1a9jp8f.png (a public transform)
How do I go about setting that variable from another script?

The other script (on the same gameobject) looks like this: https://i.imgur.com/8dTb63b.png

It's the Target I want to change

[spring adder]

Scripts can be instanced in the scene in your editor. They can also be given references to other script instances in the editor. That’s probably the most direct method if you only need one instance of each script, though there are a million ways to do this.

[strong sand]

Every object (characters) will have this script running as to use the pathfinding.

But I'm not sure how I can set the target from another script on the same gameobject.

[spring adder]

Lol, must've been drunk! Tried that before but now after a break I managed to get it on the first attempt. 😛

[still tendon]

Hi! How can I know what is the position in world space of a point inside a local UI object?
e.g. I have a scrolling list inside a hierarchy and now I have a calculated point inside that list, but I don’t know how to get the world space of that point since it is not a Game Object with a Transform but just a Vector2 :).
Thanks for the help!

[dense flame]

I think Camera.ScreenToWorldPoint works for RectTransform and UI position

[snow willow]

Raycast2D expects a position and a direction. You're giving it two positions.

It's going to interpret that second position as a direction

[crystal geode]

is there a way to make a BoxCollider2D snap to its new size/position immediately during an animation rather than morphing in between key frames?

[snow willow]

yeah just make your handles vertical

[crystal geode]

ah, thank you! I completely missed the curves menu, I'm really new to unity animation

[rich bridge]

Im trying to make a game object follow my player and remain slightly behind it, and im kinda stumped on how i can have the object move behind the player as it turns

This is where im at at the moment

[still tendon]

set its location when pressing direction keys

[rich bridge]

thats what im trying to do, ive thought of having a child object that it follows, so when the player sprite flips it will move towards it

[still tendon]

your not showing how you have it set up just a video so I assume you are using void update to constantly follow player with and off set just check if A and D and set the offset to the correct side

you should just set it up to be a child of the player that way it always follows without needing a script to update follow then just check when A or D is press then set the child local location to +1 or -1 depending on what you are pressing.

transform.SetParent(newParent); then when D is press transform.localPosition = new Vector3(0, 0, -1); or 1 for other side

[rich bridge]

ive got it perfect 🙂

[still tendon]

nice

[rich bridge]

i wanted it to be smooth, and not too snappy, so i took a camera follow script and adjusted it a bit

[still tendon]

Hello ! I can't stop my spawner from drawing "lines", and blocking my objects, at the maxY height. Like here (below the red line):

Actually, what I want to do is a spawner like this (in a loop of course). I specify that I have placed my objects manually:

A spawner with objects not too far or too tight, the one in the video is very good but I can't get a similar result 😦

[limber thistle]

You probably have a clamp function, or a if(y>height) statement somewhere

That would result in that kind of line

So without seeing your code, all I can recommend is to generate a value that is directly between your max and min heights.

@still tendon

[rich bridge]

is there any way i can prevent an object from moving too far away from the player?

i have an object that can follow the mouse, but i want it to stay within bounds of the player

[brittle summit]

How do I make the game a pixel type of thing, like tilesets and pixelated units

[grand cove]

@brittle summit Just place pixel art into the game objects and you are good to go.
But there are also guides for this all over youtube, some are pinned in the 2D art channel

[limber tartan]

I am trying to use Unity Sprite Shape and I need to add points using a script. I have been searching documentation and forums but nothing is relevent. I need to have a point places every "x" seconds on the sprite shape. Is there any way to do this? I am using Unity 2019.4 | 2D mode

[grand cove]

2d mode vs 3d mode is actually only a camera setting, so they function very much the same, but have sadly never used sprite shape, can do a quick google

Seems like most people don't add points using a script though...do you have to do that because of the level generation you have made or something? @limber tartan

[limber tartan]

I have a flower that is growing and it can move left and right, and behind it I want a curvy stem, that when the player moves, curves that way too.

That is why I need a point every x seconds, so that the stem curves

[grand cove]

you could potentially move a point every second, seems like creating one will be quite heavy...but lets see if it's possible

[limber tartan]

🧐 That is an interesting idea

Sorry for all these questions, but can you move a point up if it is lower that the player by 20 blocks?

[grand cove]

https://www.reddit.com/r/Unity2D/comments/brvbfy/can_you_edit_the_spline_of_a_sprite_shape_via_a/
This one show an example how you can edit the spline in a script, even added a gif of it.

Oh, unity also has a whole tutorial for how to work with sprite shapes

[limber tartan]

I've seen that one, but that causes issuses where the spline is like 2 pixels tall and you can barely see it.

[limber tartan]

in my implimentation

[grand cove]

Might it be because you failed to set some settings for certain nodes maybe?

[limber tartan]

Sorry I have to sleep, its like 11 pm

I'll try again tomorrow

[grand cove]

yep, sleeping on it is most of the time the best action :p

[brittle summit]

Oh OK, thx m8

[inner ferry]

Hi everyone. I've often seen people say that transform.Translate is worse than rigidbody.velocity, because it doesn't work well with collisions. But when I turned on Auto Sync Transforms the collision started working perfectly. And since the vectors are not involved, transform is also easier to change. Well, the question is: is rigidbody better than transform, and in what way?

[snow willow]

You will simply not get realistic collisions when moving the transform directly. You will only get depenetration forces

Your object will not be stopped by colliders

Unless it's moving quite slowly and the depenetration pushes it out

Not sure what you're talking about with vectors, as you use vectors for modifying the transform just as you do with modifying a rigidbody velocity

They are also not very complicated

i think you can just parent the 2d object to the text mesh pro object and when the 2d object moves the text should move with it. otherwise IDK

If i'm using rb.velocity, i can't change it freely. For example, i want to have some acceleration in my movement and speed barrier too, and i'm using this code:
private float cap = Mathf.Max(maxSpeed, Mathf.Abs(rb.velocity.x) - 0.1f);
rb.velocity.x = new Vector2 (Mathf.Clamp(rb.velocity.x + direction * walkAcceleration, -cap, cap), rb.velocity.y);
And it isn't working, for some reason.

[dusky narwhal]

Heya, could use some tips!

Style 2d topdown.

So i'm using new input system.
and i rotate the character based on the movement.
However, the update is so fast, that when i release it register a few quick frames of input
which causes the top down character to quickly slide towards the last recorded input.
and the rotation to reset.

any tips how to combat this?
Thanks!

[snow willow]

Your logic is flawed if you're trying to cap the velocity with that.

[snow willow]

Maybe share short video of what you mean and your code?

[dusky narwhal]

It's noting major, just the basic code. but i try to get wasd and controller to work well, controller does good, wasd is the issue

https://i.gyazo.com/ad1186b6c8636f0243ef5c562dba1d99.mp4

[snow willow]

Are you using Input.GetAxis by chance?

[dusky narwhal]

No sorry, im using the new input system

[main shuttle]

when I hit play I cant see my cubes in the camera

I can only see one of them

[snow willow]

Line up your camera beforehand by using the camera preview in scene view

[main shuttle]

where is the camera preview

[snow willow]

Could just be that when you release one button slightly before the other one, only the last button to be released is registered for a frame or two

[still tendon]

click on camera

[snow willow]

In scene view. Make sure Gizmos are turned on and you select your camera

[main shuttle]

ok

[dusky narwhal]

Yes that's what im getting to aswell, and try to fight that somehow xD

[still tendon]

if your camera clipping planes near is too high and your objects are with in that range your camera will just clip though them you wont see them

[main shuttle]

what should I change that to

the clipping palanes

[snow willow]

Don't change clipping

Just look at the z position

Of your camera and your object

[main shuttle]

its 5 right now

[snow willow]

Make sure they're not the same

[still tendon]

.3 near and 1000 for far

[snow willow]

Your camera usually should be at z -10 and your objects should be at z 0

[still tendon]

means you will see as close up as .3 away from camera and as far as 1000 units away

[snow willow]

For a typical 2d game

[still tendon]

oh yea forgot we are in 2d xD

[main shuttle]

eyy pog it worked

[main shuttle]

is there something wrong with this

bc its not working

[snow willow]

Time.deltaTime is unecessary for AddFOrce inside FIxedUpdate

other than that it should work

oh wait

you're also missing this @main shuttle

void Start() {
  rb = GetComponent<Rigidbody>();
}```

[main shuttle]

okay

I just get error codes when I do that

[snow willow]

such as?

[snow willow]

you may have put it in the wrong place

or copied it wrong

show code?

[snow willow]

You forgot the {

[main shuttle]

where do I put it

[snow willow]

exactly where I put it in the code I shared above

or on the next line if you prefer

[main shuttle]

i dont get the error code but its still dosent work

[snow willow]

be more specific

what does "doesn't work" mean

[main shuttle]

my "player" dosent move

[snow willow]

did you attach this script to your player?

[main shuttle]

yes

[snow willow]

Does your player have a Rigidbody?

[main shuttle]

yes

[snow willow]

Is the rigidbody kinematic?

(Also

[main shuttle]

no

[snow willow]

this is 2D isn't it?

[main shuttle]

yes

[snow willow]

Does your player have a Rigidbody or a 2D rigidbody?

Rigidbody2D***

[main shuttle]

just rigidbody

[snow willow]

why

2D physics should use Physics2D

Rigidbody2D

If this is a 2D game, with a 2D camera

your object right now is moving along the z axis

[snow willow]

which will not be a visdible motion

yeah

remove the BoxCollider

you want a BoxCollider2D

you need to use all the 2D physics stuff for a 2D game

[main shuttle]

the rigid body wount go in the script now tho

[snow willow]

right

because you need to change your variable

Rigidbody2D rb;

GetComponent<Rigidbody2D>()

[main shuttle]

I did

[snow willow]

show screenshot

you have a Rigidbody2D?

[main shuttle]

yes

[snow willow]

that code does not compile

rb.AddForce only takes 2 parameters

for a 2D rigidbody

fix your compile error first

actually it only takes Vector2

so you need like rb.AddForce(new Vector2(forwardForce, 0));

[main shuttle]

on once per frame or on start?

[snow willow]

you tell me?

whenever you want to add force

FixedUpdate is where you have it now

[main shuttle]

vecter 2 is missing a directive or an assemby reference

[snow willow]

Did you spell it correctly?

[main shuttle]

ok its fixed

but its says the name fowardforce does not exist in the curent ccontext

[snow willow]

did you capitalize it correctly?

It must match your variable name

forwardforce is not the same as forwardForce

[main shuttle]

yea it looks good I think

but its says no overload for method add force takes 3 arguments

[snow willow]

correct

we're only using 1 argument

the Vector2

you muyst have misplaced a parenthesis or comma

try to copy what I have exactly

[main shuttle]

I did

[snow willow]

show it?

[snow willow]

oh you still have the old one

remove the old one

[main shuttle]

ok i got it in the script

Can u explain what a vector does exatcly so I can learn it

[snow willow]

It's just a thing that holds an x value and a y value

in this case, we're using it to tell the rigidbody in what direction we want to add a force

we're using 2000 in the x direction

0 in the y direction

Vector3 is for 3 dimensions and is the same except it also has a z in addition to y and x

[main shuttle]

how does it know that its x not y

[snow willow]

Because we used the constructor: new Vector2(forwardForce, 0)

the first parameter is always x

the second is always y

https://docs.unity3d.com/ScriptReference/Vector2-ctor.html

[main shuttle]

oh like a graph

[snow willow]

yes

[main shuttle]

thanks alot

[forest hedge]

https://gyazo.com/4432565cb43d1beb8c333bf5a4d33ffc I'm not sure if I'm meant to ask this here cause its not really a question of exact code; more of a "how would one...". So I'm trying to make the flashlight effect stop when it hits walls, but as you can see it goes through them, right now its a sprite mask system and the tutorials I've found on youtube use raycast & meshes but collisions for me are broken on those, any ideas?

(the wall jump thing is also a bug but I'm not as concerned about that rn)

[snow willow]

Unity has a 2D light system

which includes shadow support

[forest hedge]

[coarse sentinel]

Hi guys, I need a quick question answered if its not much trouble... Can I make 2d "meshes"? instead of sprites make like polygons like the sprite editor but with the option to make holes... I don't know if I'm explaining myself properly..

[snow willow]

Just make images with transparent sections

[coarse sentinel]

But I'd like to zoom in and out without changes in quality

I intend to use solid colors, no textures

[snow willow]

that's a whole different subject

but look into vector art

Unity has a Vector Graphics package https://docs.unity3d.com/Packages/com.unity.vectorgraphics@2.0/manual/index.html

but it's still in preview

[snow willow]

so use it at your own risk

[coarse sentinel]

Like this

[snow willow]

Yes I understand

[coarse sentinel]

I might aswell make a flat 3d model...

[snow willow]

You would use something like Inkscape or Adoibe Illustrator to create SVG files

You can also make flat 3D models yes

[coarse sentinel]

Oh I gave it a read a few days ago

I plan to use the physics engine on this project, so I'll see which one is better suited for that job

Thanks

[snow willow]

You can use 2D or 3D physics either way

You can use 2D physics with 3D meshes and vice versa

rendering and physics are completely separate things

[coarse sentinel]

In terms of performance?

[coarse sentinel]

Oh thats great to know

[snow willow]

I don't think they're that different performance wise

I would imagine that the 2D engine might be faster but I can't say that for sure

[coarse sentinel]

It'll probably calculate an extra vector which will be 1 anyways

I think the svg importer is the way to go, thanks!

[snow willow]

it has freeze rotation settings

[tropic charm]

https://docs.unity3d.com/Manual/class-HingeJoint2D.html

It should. It should be easy enough to try and see.

[snow willow]

If you use rn.MoveRotation and not transform.rotation

[tropic charm]

Try rb.MoveRotation(angle); instead of rb.rotation = angle;

[orchid pewter]

I dont see any particular reason to do that but sure if your implementation calls for it

[orchid pewter]

the raycasting would detect if the player is on the ground and also detect the surface type by tags?

[forest hedge]

is there a way for me to generate 2d light from a script?

from the URP

[plain pier]

I have an issue... So I have a circle sprite and a ground (The ground I made larger on x and z) both have box colliders 2d but, when the ball falls it bounces in one spot (and does not go through) But any other spot it does go through? Anybody know why?

[rich bridge]

its probably really simple, but how can i add the players x and y coordinates to a value?

is it just + player.transform.position.x

[loud slate]

*Water.cs, I think there is a collider for the circle, did you add bounciness to your circle sprite. To add bounciness, right click to project’s asset folder then create>physical material. Name it bouncy or anything haha then change the bounciness to 1.?

Sorry to bother, but everytime i create image with a button component it doesn't work, anyone knows how to solve this?

[red umbra]

make the button component and change the sprite of the button component itself. that should work

I have a question about unity 2D.
How do I set a specific width and height to a gameObject? 
I am getting a distance between two objects and I need to set a circle around the player with the same radius (or with the same units of measurement).
How can I do that?

[snow willow]

best to start with an object with exactly 1 radius for example

then it is very easy to scale

[mild kelp]

How can I set circle radius 1? Then that would be a rectangle. @snow willow

[snow willow]

A circle with radius 1 is a rectangle?

[mild kelp]

One what? One pixel?

[snow willow]

one unit

one unity world space unit

[mild kelp]

Where can you change unity world space unit? Or just see it?

[snow willow]

Is this a sprite?

[mild kelp]

Yes

[snow willow]

If pixels per unit is 100

then a 100 px width image is 1 unit wide

so you can either change the size of the image in image editing software, or adjust that pixels per unit setting

until your circle is 1 unit

in diameter I guess

[mild kelp]

And the distance between two objects is in units? (Vector3.distance)

[snow willow]

yes

[mild kelp]

Thank you so much!!!

[plain pier]

Ok Thank You Very much!

[lucid quiver]

Hey guys, I need help with mobile input system, basically when I move on my joystick controller my character also shoots at that position, i want to set it so i can tap on screen anywhere in the scene and shoot there, can someone help me with this who's not too busy?

[plain pier]

Just one thing..., It wont let me put the material on the circle...?

Oh it worked

Ty

[loud slate]

@plain pier I am a week or so in unity, I am glad it helped you😊.

[robust glade]

    void Update()
    {
    if(Input.GetKey(KeyCode.Space)){
//do something
//wait like 2 seconds
//do something after
    }
    }

How do I wait in this?

[snow willow]

use a coroutine

[robust glade]

how

i have barely done any c#

[snow willow]

void Update()
{
    if(Input.GetKey(KeyCode.Space)){
        StartCoroutine(WaitThenDoSomething());
    }
}


IEnumerator WaitThenDoSomething() {
  yield return new WaitForSeconds(2f);
  // Do the thing here
}

You will also need using System.Collections; at the top of your file.

[robust glade]

ok

thx

[snow willow]

But aklso be careful

Should probably use Input.GetKeyDown instead of Input.GetKey

[robust glade]

ok

[snow willow]

otherwise you will be doing the thing for every frame the key is pressed

[robust glade]

lol

        Vector3Int cellPosition = Tilemap.WorldToCell(transform.position);
        transform.position = Tilemap.GetCellCenterWorld.(Vector3Int(0,0,0));```

hello i'm trying to get my "character" to use grid movement but i can't make it work. i was wondering if someone have an idea about this or what i'm doing wrong

[snow willow]

Tilemap.GetCellCenterWorld.(Vector3Int(0,0,0));

Something's missing here

Tilemap.GetCellCenterWorld().(Vector3Int(0,0,0)); maybe?

also

[full nexus]

Can anyone tell me why my character seems like they're "stuttering"?

It look like the character doesn't have vsync.

Here's my code if that means anything:

    float horizontal;
    float vertical;
    float moveLimiter = 0.7f;

    public float runSpeed = 20.0f;

    void Start()
    {
        body = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        // Gives a value between -1 and 1
        horizontal = Input.GetAxisRaw("Horizontal"); // -1 is left
        vertical = Input.GetAxisRaw("Vertical"); // -1 is down
    }

    void FixedUpdate()
    {
        if (horizontal != 0 && vertical != 0) // Check for diagonal movement
        {
            // limit movement speed diagonally, so you move at 70% speed
            horizontal *= moveLimiter;
            vertical *= moveLimiter;
        }

        body.velocity = new Vector2(horizontal * runSpeed, vertical * runSpeed);
    }```

[snow willow]

Vector3Int(0,0,0) needs to be new Vector3Int(0,0,0)

[snow willow]

This is fishy in FixedUpdate:

        if (horizontal != 0 && vertical != 0) // Check for diagonal movement
        {
            // limit movement speed diagonally, so you move at 70% speed
            horizontal *= moveLimiter;
            vertical *= moveLimiter;
        }```

what happens if you get two physics frames?

You will multiply horizontal by .7 twice

and vertical

you probably want to only modify a local copy

The other thing is

physics movement is naturally "stuttery"

unless you turn on rigidbody interpolation

because the physics update is not synced with the frame update

[full nexus]

Even before implementing fixed update it did the stuttering.

I've turned on rigidbody interpolation aswell.

[snow willow]

you'd have to share your code in whatever other state it was also stuttering in

but if you were using Rigidbody, that moves in sync with FixedUpdate no matter what

interpolation should fix it though

[gaunt charm]

i already try this same error

[snow willow]

It is one of your errors

you have many

scroll up I mentioned another one

above the giant code block

[gaunt charm]

i know i saw it

someone. i already try the new(new Vector3Int(0,0,0));

and i add the () to the other line too

[snow willow]

show your new code, show what your errors are

[full nexus]

I don't even remember what other things I did, I've tried a load of different movement techniques and the stutter remains, even in some of my other projects.

Is there a better way to move the character in all directions?

I'm still new to this, so I'm sorry if I'm not understanding

[snow willow]

And maybe break that line of code up into multiple lines so it's easier to find and fix the errors

[gaunt charm]

it's with the code but here again https://cdn.discordapp.com/attachments/763500535554375750/820129365378596953/unknown.png

[snow willow]

share more of your code

the whole file if possible

[gaunt charm]

sure sec

[snow willow]

        Grid Tilemap = transform.parent.GetComponent<Grid>();
        Vector3Int cellPosition = Tilemap.WorldToCell(transform.position);
        transform.position = Tilemap.GetCellCenterWorld().(new Vector3Int(0,0,0));```

this is not right

You got a Grid object

and you're trying to call functions on it like it's a Tilemap

just because you named it "Tilemap" doesn't make it a Tilemap object

What is a "Grid"

is that a custom class you made?

WHy aren't you just using the map variable you have already defined

that is a Tilemap

then finally the way you are calling GetCellCenterWorld().(new Vector3Int(0,0,0)); is wrong

it should be GetCellCenterWorld(new Vector3Int(0,0,0));

[gaunt charm]

you told me to try this way

[snow willow]

I was telling you that to fix one error you had

which was the missing parentheses

Just becuase I didn't also fix your other error doesn't make it wrong

basically the dot you had was super confusing

[gaunt charm]

and about the grid im really new on unity so im trying to figure it out. just wondring if i could get some help trying to fix that

[snow willow]

You most likely just want to use map

[snow willow]

    void Start()
    {
        destination = transform.position;
        mouseInput.Mouse.MouseClick.performed += _ => MouseClick();

        Vector3Int cellPosition = map.WorldToCell(transform.position);
        transform.position = map.GetCellCenterWorld(new Vector3Int(0,0,0));
    }```

[gaunt charm]

it's like i didnt add anything to it with that code

[snow willow]

does it compile?

that's step 1

[gaunt charm]

yes

i edite my comment

[snow willow]

then you're in better shape than 5 minutes ago

add anything to what?

[gaunt charm]

the 2 new lines Vector3Int cellPosition = map.WorldToCell(transform.position); transform.position = map.GetCellCenterWorld(new Vector3Int(0,0,0));
they are like commented. they added nothing to the script

[snow willow]

not sure what you mean

I mean it's true that Vector3Int cellPosition = map.WorldToCell(transform.position); won't do anything

you're just reading a value out to a variable and then ignoring it

[gaunt charm]

https://docs.unity3d.com/ScriptReference/Grid.GetCellCenterWorld.html this is where i got it from

[snow willow]

Ok

But you have a Tilemap

https://docs.unity3d.com/ScriptReference/Tilemaps.Tilemap.html

which inherits from GridLayout

You already have your Tilemap reference

why do you need a separate Grid reference?

It's the same object, with the same method

in any case - what are you actually trying to do?

[gaunt charm]

snap the character to the grid. so only move inside the grid

[snow willow]

ok and how are these 2 lines in start supposed to do that?

Start only runs once

You'd need to make a change inside MouseClick()

to snap the mouse position to the grid

[gaunt charm]

ty for the info i will try to find out something about this

[lapis moth]

im trying to make a main menu but i get the error cs0103 scenemanager does not exist

[snow willow]

Did you capitalize it properly? SceneManager

And do you have using UnityEngine.SceneManagement; in your file?

[broken skiff]

I am doing a clicker, why clicks are not counted, I think this is due to an error in the script. Who can help solve the problem please write to me

[jovial narwhal]

how do you delete objects?

[still tendon]

How can you make the grass sprite go over the background instead of being behind it?

Nevermind, already figured out. I changed the sprite's Z position to -0.01

[marble badger]

anyone here

Have a question:
After performing a raycast, if it hits an object then i find the hit.distance and assign it to the objects velocity.x
It makes the object transfer to that position immediately. That how i do kinematic collision checks. But when i Debug.Log(hit.distance) it returns a value between the origin point of the raycast and the collision point.
then what does actually gets assigned to the velocity? is it a vector? what is it?

[mild kelp]

I have a question about unity 2D.
For some reason button command is not working.
And the weirdest part is that the Debug.Log is happening, but everything else isn't. 
Does anybody know why is that?

[spring adder]

Well if it’s showing the log then it’s executing the function, unless you have another log that logs ‘y.’ So what is it not doing that you want it to do?

[mild kelp]

It is not changing the variable and not destroying the object. I tried putting in some other functions too, but only Debug.Log is executing.

[spring adder]

what other functions?

[mild kelp]

For example changing other variables.

But only thing that is happening is the Debug.Log @spring adder

[minor harness]

where is the option to import my sprite

I cant find it

someone just please

tell me where it is

[mild kelp]

Just drag your sprites from file explorer into unity

[minor harness]

oh ok

I'm dumb

what if it's a Sprite sheet

[mild kelp]

???

[minor harness]

@mild kelp what do I use to crop it

sorry of I'm being annoying

[mild kelp]

Do the same, and after importing go to sprite editor to slice it.

[minor harness]

thanks

that helps a ton thanks

wait

it hasnt done anything

[sweet bloom]

hey guys i'm trying to make an enemy move from a point to another but can't seem to make it work

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

public class MoveSide : MonoBehaviour
{

    public float speed;
    public bool MoveRight;

    // Use this for initialization
    void Update()
    {
        // Use this for initialization
        if (MoveRight)
        {
            transform.Translate(2 * Time.deltaTime * speed, 0, 0);
        }
        else
        {
            transform.Translate(-2 * Time.deltaTime * speed, 0, );
        }
    }
    private void OnTriggerEnter2D(Collider2D trig)
    {
        if (trig.gameObject.CompareTag("turn"))
        {
            if (MoveRight)
            {
                MoveRight = true;

            }
            else
            {
                MoveRight = false;
            }
        }
        
    }
}

this is the code i used, it can go back when it reaches one bound but then when it reaches the left one it just goes trough the collider without triggering

[mild kelp]

When you are in the sprite editor there is an option slice. Push that.

[minor harness]

@mild kelp it wont let me

its grey

[mild kelp]

I don't know why is that, but the slice option is still there.

And it still works

[minor harness]

it still has the massive border but there is only one sprite

[mild kelp]

You also need to choose multiple as a sprite mode.

[minor harness]

how?

I'm sorry I'm really new to this

I really shouldnt have done this

[mild kelp]

???

[viral locust]

Someone know how to make a script on a 2D isometric map

Like that ?

With movement point

You'll need a pathfinding algorithm

But to do that and get the visual effect too will require a lot of work

And without the effect

It's more easier

I have a question about unity 2D.
What is the toString() format, so if there is a number smaller then 10, it is going to put a zero before it. (For example 01, 02, 03, 04 ... 10, 11 12)

[mild kelp]

Does anybody know this???

[snow willow]

https://docs.microsoft.com/en-us/dotnet/standard/base-types/standard-numeric-format-strings

It's all documented there

It's also a C# question which isn't really related to Unity FYI

[mild kelp]

I am trying to use "D2", but is throes an error: The specified format 'D2' is invalid.

[snow willow]

How are you calling it

[mild kelp]

string.Format("0:{0}", objectShower.timeLeft.ToString("D2"));

[snow willow]

Is timeLeft an int?

Or a float

[mild kelp]

It is a float

[snow willow]

You have to use the float specifiers then

[mild kelp]

Ok, thank you! (I will just make it int)

[umbral patrol]

Is there a way I can make a game that toggles a camera to view all sprites as either pixelated or with a bilinear filter?

[snow willow]

You have to register the button you want in the Input Manager (it might already be registered as "up" or "forward" or something, not sure).

I have a question about a movement script.

When i playtest my scene, i enabled debug.log, the console is displaying the numbers, but the character isn't moving at all.

[snow willow]

Reversing the scale of stuff causes all kinds of issues like that so I'd usually not recommend it

If you're using a SpriteRenderer there's a "Flip X" option or whatever to reverse the image

why does the rigid body jitter when interacting with walls

[rain ingot]

i have a sprite with a animation how can i switch between frames using code and a int

[rare parrot]

show code

[rare parrot]

implement character movement by changing velocity of rigidbody, dont use transform.translate

ie

public class PlayerController : MonoBehaviour
{
    Rigidbody rb;
    public float speed = 1.0f;
    Vector3 movement = new Vector3();

    private void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void FixedUpdate()
    {
        rb.velocity = new Vector3(movement.x, movement.y, 0);
    }

    void GetInput(float speed)
    {
        // setting input variables
        movement.x = Input.GetAxisRaw("Horizontal") * speed;
        movement.y = Input.GetAxisRaw("Vertical") * speed;
    }
}

[rare parrot]

switch between frames? animation clip should contain all frames for that clip and play them automatically

ie

unless your question is how to transition between animation clips using code and a int

[rain ingot]

ok i have 3 of the same sprite on a animation

i need to switch between them

is a animation a good way to do i

t

[rare parrot]

show animator window

[rain ingot]

ok

[rare parrot]

if its not already in ur editor, navigate window > animation > animator

[still tendon]

how do you import unity stuff into roblox

[rain ingot]

idk

wrong channel

[still tendon]

which channels? sorry

[rare parrot]

ok so you have 3 key frames, are they all part of the same animation?

[rain ingot]

yes

[rare parrot]

does the animation play when you enter game mode?

[rain ingot]

yes

[rare parrot]

why would you need to switch between them

[rain ingot]

its a where is waldo type of game where u need to find the right collor one

[rare parrot]

can u show what the sprite of each keyframe is

[rain ingot]

.

https://www.imgonline.com.ua/result_img/imgonline-com-ua-resize-c2ViWwgtZjyTbdRz.jpg

whitout the white bg

[rare parrot]

what conditions for the int would you want the sprites to switch

[rain ingot]

0 1 2

[rare parrot]

how would you want the sprites to switch

[rain ingot]

any way

[rare parrot]

why would you need 0 1 2 to switch between sprites

[rain ingot]

idk

anyway is fine that i can change in rubntime

[rare parrot]

how do you want to change the sprite in runtime

[rain ingot]

everytime u click on it it changes it

and randompos

[rare parrot]

ok thats the answer im looking for

animation would not be ideal way to implement that

[still tendon]

um can i ask or am i barging in

https://stackoverflow.com/questions/66624074/when-character-flips-fire-point-does-not-rotate-2d the question

[rare parrot]

if you want to change the sprite on click, create script on the gameobject, declare a sprite array and create a function where you assign an int variable a random number between 0-2 for index of sprite array, then assign sprite renderer the sprite array[index]. reference this method on click

[rain ingot]

    public Sprite image0;
    public Sprite image1;
    public Sprite image2;
         public Sprite[] imageList = new Sprite[] {
                       image0,
                       image1,
                       image2,
                      ...
     };
```?

[rare parrot]

i wouldnt declare a sprite object for each image

just the array

you can set size and initialize the array in the inspector

[rare parrot]

what you mean by fire point?

[still tendon]

the point where the bullet spawns

when i face right it spawns and goes right

which is what i want

but

when i face left it spawns and goes right

i want it so when i rotate my sprite

i also rotate the fir epoint

i already rotate the sprite and the gun

dont know how to rotate the point

[rare parrot]

is the fire point a child of the object which runs the script to flip the player

[still tendon]

?

it flips with it

it just doesnt face the same way

[rare parrot]

nvm

[still tendon]

?

[rare parrot]

change the velocity of the bullet to negative when left input is detected

[still tendon]

what

[rare parrot]

or

[still tendon]

please dumb it down

i started unity and coding a week ago
