[spice thistle]

someone know mybe what i need to do?

[potent iris]

maybe the animation is like just to short and you have to loop the animation

[split pasture]

guys, can anyone help me with socre system?

score*

[spice thistle]

so i need to create a loop for the animation?

[split pasture]

i think yes

pls anyone

[simple lintel]

if you touch anything will add a score, add BoxCollider2d and enable IsTrigger = true;

make a script in the object, ad void "OnTriggerEnter", "OnTriggerStay", or "OnTriggerEnter".

more in https://docs.unity3d.com/ScriptReference/Collider.html

[potent iris]

send me a message with more exact info

I need help with Tilemaps in Unity, C# i want to load a preocedural generated world just partial in like chunks, can anyone help me with that?

[split pasture]

check dm

[simple lintel]

i did'nt know all about tilemaps anw

[potent iris]

thats sad

[potent iris]

isTrigger should be true on the coin, not on the player

[simple lintel]

yes i mean't that

[potent iris]

yeah i know but he prolly didnt know

[still tendon]

I believe is the only way to make persisten objects so u gotta work around that

U coul save ur death counter to playerprefs and pull it back it at awake in a New canvas

In the next scene

[rocky mirage]

its ok i find it

[still tendon]

me too

[teal plinth]

Sorry, really dumb question. How can i create a triangle in my 2d project? I cant find it, there are only all the other forms. Ive already searched under --> 2D Object --> sprites.

[simple lintel]

just download triangle mask image

keep script in that, so add variable "{the up image class name}"

in the collision trigger, add trigger "Take Damage()"

[spice thistle]

someone already help me ty tho!!

[simple lintel]

also ask... in movement, when i walk to left, want to flip x the sprite, but my script gave error

how to convert they to a boolean?

forget the bottom code

[snow willow]

You need to express what it is you want to check with the if statement

if( what? )

[potent iris]

+= means x = x+y

So += is not =

[still tendon]

how do i fix this problem

this is the really simple movement code

[snow willow]

Can you first explain what your expectations for this code are and how they are differing from what is actually happening?

[still tendon]

the clipping into the wall

[snow willow]

You are modifying the position of your object's transform directly in Update

that bypasses the physics engine

and causes things like clipping into walls

[still tendon]

does it work with fixedupdate?

[snow willow]

especiaally since you have a Rigidbody, you should not modify the positon of your object directly like that

[snow willow]

No - you can't set transform.position directly anywhere

or you will have this issue

For a Rigidbody you should only move it via setting the velocity or adding forces

[still tendon]

oh okay

thanks for explaining

[full oyster]

My square sprite(player), always goes up. I can't get to fix it. I don't have a script for that. I have a rigid body and a box collider component for it.

Can anyone help?

[snow willow]

if it's going up it's because

• You have a script moving it up somehow
• gravity is pointed up
• some other force from your scene is pushing it

[potent iris]

@snow willow you seem familiar with unity, are you familiar with tilemaps?

[snow willow]

nope

never used them

[potent iris]

oh sad

[full oyster]

But I don't have a script for the player movement

[full oyster]

How do I make gravity point down?

my character is flying up for some random reason

i can't figure out why

[snow willow]

Edit -> Project Settings -> Physics has the universal gravity settings

[full oyster]

this is what I see

[full oyster]

Where should I change it?

[snow willow]

the first setting

Gravity

make the Y part negative

so things fall down

instead of up

😄

[full oyster]

ohhh ty

tysm

[ruby karma]

Apple didn't fall on newton. Newton fall on applee

[potent iris]

if anyone needs help, hit me up im free to help

[light roost]

I am making an enemy that shoots snowballs like bullets (the snowballs move in a line and they don't lose speed). But mine just stops immidietly

[grim coral]

Guys I'm so confused how do I make it so that my when my 'Player' touches my 'Enemy' my player respawns? also would I need to make checkpoints first?

[abstract olive]

Check for collisions on your player script, if the thing it's colliding with is tagged with Enemy, then reposition your player back at some other point.

[grim coral]

This is probably a stupid question but how do I do that?

[abstract olive]

Look up tutorials for:
https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html
https://docs.unity3d.com/Manual/Tags.html

Or look at the examples in the docs.

[potent iris]

Simply you use a function called OnCollisionEnter2D (collider2D collision) inside it you say if (collision.compareTag("Enemy") and the you respawn the player

[full oyster]

I have this code in Visual Studio

its the movement script

but for some reason I don't get a feet transform in Unity.

[rapid hedge]

Did you save the code with CTRL+S

Wait we're working on the same project/tutorial LOL

Also, check for errors in the console when you run.

Finally, could I pls see what you have for the public vars in the inspector by scrolling down.

[full oyster]

not sure what you mea by that

mean*

@rapid hedge

[snow willow]

Can you share a screenshot of the actual script component on your object? It's not pictured in your screenshot

[full oyster]

ohh

ok

U mean like this

?

[snow willow]

Yes

See how Feet says "None"

[full oyster]

yeah

[snow willow]

You need to drag something there

[full oyster]

but i don't have a transform there

even though it is in the script

[snow willow]

what do you mean

the thing in the script creates that empty slot

it is your job to fill that slot with something in the inspector

[full oyster]

can I see yours since u are doing the same project?

[snow willow]

Presumably whichever object is supposed to represent your players' feet

I am not doing the project

that was someone else

[full oyster]

oh

ok

[snow willow]

you likely skipped a part

where they add a feet object to the player

I think it just needs to be an empty object that is a child object of the player

[full oyster]

yeah so the player is the parent

but I can't add a child to it

https://www.youtube.com/watch?v=1bHVsxw_o7o&t=322s

[snow willow]

why not

[full oyster]

here is the link for what I am woking on

the child has a to be a transform

[snow willow]

30 seconds in

is where they add the feet object

[full oyster]

yeah

[snow willow]

you need to do that part

[full oyster]

lemme see

ohhhh

tysm

that helps

[snow willow]

and then

at 5:30

is where he drags it onto the script

[full oyster]

got it

[rapid hedge]

O

Goodie

[full oyster]

y

@snow willow I have a new problem. I have changed the code and followed the tutorial but I can't jump. It is the same code as before

[snow willow]

Start using Debug.Log and find out if your ground check is working, if your jump button check is working, etc..

[full oyster]

how do I do that

[full oyster]

Can you give me an example

[snow willow]

Debug.Log("Hello!");

[full oyster]

but y would I do that?

[full oyster]

that would just print out something in the console

[snow willow]

indeed

[snow willow]

To diagnose your problem

to figure out why you can't jump

[full oyster]

i will try

[snow willow]

For example, put one of those inside the Jump function around line 31 to make sure it's actually running

Start thinking like a detective 🙂

[full oyster]

I don't see anything in the console

[snow willow]

then that code isn't running

you've learned something

[full oyster]

how do I fix it?

[snow willow]

now walk back in the script

and figure out why it's not running

[full oyster]

ok

[snow willow]

Looks like it's being called inside an if statement on line 18, right? And that if statement requires both isGrounded() and Input.GetButtonDown("Jump") to be true. So maybe print out the value of both of those things to see what's going wrong?

[full oyster]

ohhh ok

got it

[viral veldt]

any good free pixel art and/or 2d art drawing programs?

[snow willow]

[viral veldt]

ok thanks!

[simple lintel]

Aseprite is good tho

[viral veldt]

it cost money tho ://

[still tendon]

@viral veldt You can build it for free legally

Want a video on how to do that?

[viral veldt]

oh

cool

sure

[still tendon]

But if you ever have the money and time, I reccomend you buy it too. To support the developers of aseprite.

(This is actually how I first got it.)

[viral veldt]

thank you!!!

[red moss]

Hi everyone, I have a question on what the best practices are to setup a character controller on a 2D platformer-like game, namely on how to link the behaviour of the current state of the player (idle, walking jumping wall grabbing etc) to its animation. I setup a state machine pattern for the main character script, and then use trigger variables to swap between animations on enter/exit states. I know it is also possible to simply add code to the animator state itself (which I dont do). How do you usually do it?

[potent iris]

i made it with the animator itself like if my movement variable which was linked to the Axis of horizontal was higher or lower then 0.1 or -0.1 it changes the state

[soft nymph]

hi i am new to unity and as my first project i wanted to make a 2d ragdoll game and i want my ragdoll to be pickable and throwable like in mobile game beat the boss using a tutorial i made my ragdoll https://generalistprogrammer.com/unity/unity-2d-ragdoll-character-tutorial/ and using a tutorial i made grab and drag mechanic https://www.youtube.com/watch?v=55TBhlOt_U8 but when i grab a part of ragdoll the other parts of the ragdoll go crazy how can i solve this

[chrome fern]

does anyone have a good method for having a sprite update the max value on a slider?

[snow willow]

sprites are just image files

You can update the max value on a slider by setting this property https://docs.unity3d.com/ScriptReference/UIElements.BaseSlider_1-highValue.html from a script

[chrome fern]

I tried this and the max value goes up but not the slider maxValue

 if (LevelManager.instance.maxHealth > slider.maxValue)
        {
            slider.maxValue = LevelManager.instance.maxHealth;
        }```

[chrome fern]

I figured it out

[full oyster]

Another good pixel art software is UPA Toolkit by Brackeys

[unique turret]

I'm trying to get the Cinemachine camera to follow a gameObject that is tagged with "playerTag", but it's not working. Here is my code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Cinemachine; 
using Mirror; 

public class CameraManager : NetworkBehaviour
{
    string playerTag = "Player";

    // Start is called before the first frame update
    void Start()
    {
        
        GameObject newPlayer = GameObject.FindGameObjectWithTag(playerTag);
        GameObject.Find("CM vcam1").GetComponent<CinemachineVirtualCamera>().Follow = newPlayer.transform;
        
    }
}

[knotty barn]

What happens? Errors?

[unique turret]

Doesn't give off any errors, just doesn't work

[knotty barn]

Check if Follow is set after that runs

[formal scarab]

Is that a freelook camera?

Oh, sorry, just saw I'm in 2d lol

[unique turret]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Cinemachine; 
using Mirror; 

public class CameraManager : NetworkBehaviour
{
public GameObject newPlayer;
public Transform FollowPlayer;
private CinemachineVirtualCamera vcam;

    // Start is called before the first frame update
    void Start()
    {
        CinemachineVirtualCamera vcam = GetComponent<CinemachineVirtualCamera>();
        GameObject.Find("CM vcam1").GetComponent<CinemachineVirtualCamera>().Follow = newPlayer.transform;
    }

    void Update()
    {
        if (newPlayer == null)
        {
            newPlayer = GameObject.FindWithTag("playerTag");
            if (newPlayer != null)
            {
            FollowPlayer = newPlayer.transform;
            vcam.LookAt = FollowPlayer;
            vcam.Follow = FollowPlayer;
            }
        }
    }
}

I tried this to fix it, but it still doesn't work

[unique turret]

This is so it automatically finds the player with tag playerTag

[knotty barn]

Yea, just meant check if the field is set when you do it in code

[unique turret]

Yeah it is

It's just not following the player for some reason

[knotty barn]

And it points to the right transform? What if you set it manually?

[unique turret]

Ill try that

Nothing still happens when I set it manually, because nothing changes

[knotty barn]

So the camera rig isn't working?

[unique turret]

I assigned this script to the camera itself

[knotty barn]

I meant change the Follow field on the camera, not on the script

And make sure the value is on the camera as expected

[unique turret]

Oh okay one sec

[unique turret]

That works but every time I disconnect from the server and join back it stops working

I'm using Mirror for the networking

[knotty barn]

Now check if the script is setting the value

[unique turret]

It is

[knotty barn]

So the value on the camera is the same as when you set it by hand?

[unique turret]

Yeah

[knotty barn]

Then I have no idea 😄

[unique turret]

😄

I don't have any idea what to do

[unique turret]

When I leave and join back this field becomes empty, is there away to have it automatically set into this field and not the scripts field?

This one stays filled in

[knotty barn]

It stays filled or is refilled?

[unique turret]

refilled

[knotty barn]

Yea what you are trying to do is the way to do it. Not sure why it isn't working

[unique turret]

It's confusing, lol

nvm it was always filling, Its just filling wrong

[viral veldt]

ah when i see the name brackeys i know its good

[unique turret]

I got it working, but when I spawn in another player It doesn't work for the new player

do you know why?

I'm going to bed, hopefully a solution will come to me when I wake up, lol

[knotty barn]

@unique turret Are other players also tagger with playerTag?

[unique turret]

Yeah they are

I just spawn in the same prefab for every player

[knotty barn]

Then the FindWithTag is probably problematic

[unique turret]

Alright so what should I use?

[knotty barn]

I would consider moving this sort of logic to the spawner, which could set up the UI target, camera target etc

On the spawner you can probably figure out when you are spawning a GameObject that belongs to the player

[unique turret]

Alright thanks, I'll try some stuff in the morning

Hello, I got a question regarding the Pixels Per Unit Setting.
I have a 100x100 pixels Sprite and imported it into Unity. I left the PPU setting at 100.

What's the problem here?

[sage imp]

Hey! I was wondering how I would make a game that I'm working on similar to spore where I can drag and drop parts on a 2d character in order to affect appearance, movement damage, health, etc?

I have a character

And pieces

[snow willow]

Spore's character creator is quite complicated

[left lotus]

Keep in mind Spore had over 100 developers, 8 years of development, and they still had to simplify their final version of the character creator from their original idea

[snow willow]

Man what a disappointment that game ended up being lol

[left lotus]

😦 still have the box. If only

[sage imp]

I only want to be able to click and drag onto body

And be able for it to carry on throughout scenea

Scenea*

Scenes*

[snow willow]

Then you just want to Instantiate some sprites as children of the main body I suppose

[trim fjord]

My particles (in a 2D project) are showing up in the editor (when selected) but not in the game preview

Has anyone experienced something similar and know how to resolve this?

[left lotus]

They have Play On Awake checked? Or if not, you're managing the Play() through a script?

Do they have Loop checked (if they should loop)

[left lotus]

Oh also, are you running your game when doing this. If the game isn't playing the particles won't run in the game preview

[trim fjord]

Yes, play on awake and loop checked, playing the game inside Unity

So weird...

No background, so they aren't being hidden by a layer or something

[left lotus]

Can you try swapping the material for a moment or something? Are your particles maybe transparent, or something else that would prevent rendering

[trim fjord]

Changed to Grid instead of Spites, no change

[cyan yoke]

my 2D collision isn't working 😦

[trim fjord]

Is there a way to hide certain types of objects in the game preview, or something?

[cyan yoke]

I have 2D Box colliders on both objects, but nothing shows in debug

[trim fjord]

@left lotus Found it 🙂 I had for some reason set Z Y and X positions to some weird values

[left lotus]

haha nice

[trim fjord]

lol!

[cyan yoke]

for OnTriggerEnter2D, you need both objects to have 2d colliders and one to have a rigidbody right?

I'

I've done that, but it is not occurding

[left lotus]

The triggering one has isTrigger checked, and the one with a RigidBody does not have isTrigger checked, is that right?

Is the RigidBody on the same object, or a parent object, of the Collider?
And is the script with OnTriggerEnter2D in it also on the object with the trigger-Collider?

Also confirm you don't have the objects at different depths (z value)

[cyan yoke]

same z value not working

oh wait got it

I forgot to put the script on the objects

[native pelican]

Is there any way to remove this annoying twitching whenever I instantiate a prefab inside a Scroll View?

[left lotus]

It looks like the messages have an animation to quickly slide-down-from-up into view

Is there any kind of animation or anything on them? If not, how are you instantiating them inside the view

[native pelican]

I have prefabs with empty text and I fill them up with the message text after setting SetActive to false as soon as I instantiate the prefab. Then I set SetActive to true to make the message appear on screen.

I'm not using animations/tweening at all in this case.

[limber kraken]

Ok so i tried to follow brackey's 10 minute making a video game Video and um, i don't know what i did rwong. Can someone explain?

second image: brackey's. third image: my code ._.

Your code doesn't match the brackeys image? Also the brackeys screenshot is from an incomplete portion of the code that won't compile until he's finished typing

[limber kraken]

Oh

So to make a 2D game, i need to:
-rwite info on paper from start to finish
-git gud at speedrunning

[left lotus]

huh?

I mean at the very least you need to watch the video until he finishes typing

[viral veldt]

aloha

i need help

i cant find the condition tab in my inspector

how do i add it?

[snow willow]

conditions are part of transitions

which are the arrows between your states

[brittle helm]

Looks like if you make setactive true then later the layout system starts to place to the correct position (based on size). You could try yourRect.ForceUpdateRectTransforms(). But I am not sure which rect you need to use there after using SetActive(true).

Also you can do LayoutRebuilder.ForceRebuildLayoutImmediate(parentRect). This should force the layout system to rebuild. Better try this first.

[native pelican]

Ok, let me try.

Oh, wonderful. The twitching disappeared after adding LayoutRebuilder.ForceRebuildLayoutImmediate(parentRect) Thank you so much @brittle helm !

https://pastebin.com/LCvzGTDu

[left lotus]

Lines 48 and 52 you have 'if' statements for touch.phase == TouchPhase.Moved and touch.phase == TouchPhase.Ended, all of your logic is happening when touch.phase == TouchPhase.Ended

You want to move it into the (touch.phase == TouchPhase.Moved) region, but then you'll need a little bit more code a the top to check if the distance is above whatever distance you want as your threshold

[mellow sleet]

[tidal onyx]

Anything look wrong with this code? Essentially, it puts a raycast2d on a player (down from their feet) to check if there is ground below them, which is represented by the bool grounded.

Essentially, grounded is never set to true when I run the game despite the if statement there. I am wondering if there is anything wrong with this code that could be causing this

As can be seen by the red debug lines, the raycast is colliding with the tilemapcollider (green)

Thanks in advance for any help

[native zephyr]

anyone know how to setup A* from arongranberg with Unity's grid system? setting the cell sizes to the same value in both won't result in an overlap at all.

[vocal condor]

Basically grounded = (hit.collider != null) which would imply hit.collider == null if the lines are red.

[tidal onyx]

Thank you

[vocal condor]

So there weren't any valid colliders hit during the raycast.

Hello, I am having trouble with adding a jump movement. I want it to only jump when it is on the ground. So I tried adding a groundCheck feature. But now, I can't jump at all. Here is my code. Can anyone help?

[knotty barn]

Is the ground check working? Debug values by logging them or using breakpoints in Visual Studio

[full oyster]

lemme try that

[tidal onyx]

Wait @vocal condor , I am a little bit confused. I think I get what you are saying but what makes the collider not valid? Sorry

[vocal condor]

If they do not have the correct layer that you're filtering for.

Being trigger mode may effect this as well depending on your global settings.

QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal

public static bool Raycast(Vector3 origin, Vector3 direction, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);```

queryTriggerInteraction Specifies whether this query should hit Triggers.

[tidal onyx]

Ok thanks I got it 👍

[unique turret]

Still haven't figured out a good solution for this camera, I'm using Mirror to spawn them in, The red square is the place where I select what prefab I want to be spawned in when the player presses play

[knotty barn]

You should be able to handle the spawning yourself in your network manager. You can probably copy the implementation from the base network manager to start with

[thorn veldt]

you were very correct

and I thank you

additionally, where would something like this be appropriate?

[scenic zenith]

Hey, does anyone know how to make a simple 2d lever? when the player walks to the right the lever switches to the right sprite and when he walks to the left, if switches to left one but i cannot seem to get it to work since on TriggerEnter2D dosent have contact points and i am using that to check when the hit location is... and if i use collider it just kind of bugs out and its not the way i want

[still tendon]

hi, I am trying to get only the rotation of a vector so that my character will always run in the direction its going, here is the code that I have so far, but I dont know how to get only the direction of the vector
Vector3 direction;

void update()
{

  direction = GetComponent<Vector3>();
  direction = Quaternion.LookRotation;

}

when I do that, it brings me the error "Cannot convert method group 'LookRotation' to non-delegate type 'Vector3'. Did you intend to invoke the method?"
so can anybody please help me?

[still tendon]

does anyone know to make UI buttons stack vertically, so that if a button in between is disabled, the one above will move to stick to the one below?

[still tendon]

but did you wanted to invoke the method. did you wanted to do this ```cs
direction = Quaternion.LookRotation();

instead of ```cs
direction = Quaternion.LookRotation;

[gray brook]

Look up vertical layout group and sibling index

[snow willow]

there's a lot wrong with this code snippet... what eactly are you trying to get the direction of @still tendon

• update should be capitalized
• Vector3 is not a component
• is direction actually a declared variable anywhere?

[turbid wasp]

Hey guys, I need a lil push into the right direction. I'm trying to have it so that I have an object attached to the player which rotates around the player based upon the mouse's position on the screen. I want object to collide and stop on things within the environment without trying to phase through and/or fling the player around (like "Getting Over it").

It would be great if someone could redirect me to a source that could help me.
Here's an image of what I mean :

[turbid wasp]

I've tried the following

    void Update()
    {
        transform.position = player.position;

        Vector2 direction = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
        float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
        Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.forward);
        transform.rotation = Quaternion.Slerp(transform.rotation, rotation, speed * Time.deltaTime);
    }

But I have the problem of the "Stick" simply phasing through objects like its Martian Manhunter. Instead of colliding and Stopping

[snow willow]

you're going to need to use a physics-based solution. Modifying the Transform directly is going to completely ignore physics, as you have seen

[turbid wasp]

can you think of any solutions off the top of your head that I can look into?

[snow willow]

A rigidbody on a hinge joint probably

[turbid wasp]

So I can keep the script the same but put the "stick" on the hinge joint instead of just your standard child/parent relationship?

[snow willow]

modifying the rotation of the transform directly in your script is not going to work

no

[compact gate]

Hi, does anyone know a way to "pixelate" a Line Renderer ? I think my best solution could be a shader ?

[snow willow]

Yeah a "pixelated" shader would work nicely

[still tendon]

thanks but I realized that doing that isnt gonna work, so I found a way better and simpler solution, which in short is just making the detection float for when to switch animations a bit higher and that did the trick😂

[compact gate]

I ended up using a render texture, it is even simpler

[woven trail]

I have a problem with my 2d game. I want to make an ice block that has 0 friction but I can't make it work. I have tried adding a physics material 2d with 0 friction but it didn't work. I added 0 anglular drag in my player, I added a rigidbody on the tileset and set the angular drag there to 0 and it still doesn't work. I don't know how to do it

[still tendon]

unity somehow can see 5 errors but i have been looking at this script over and over again and i think it looks fine

[gray brook]

What are the errors?

[still tendon]

I'm very new to Unity and setting up games in general. I just set up a collision box around the camera so objects in the game don't go off the sides of the camera out of view, but if I change the aspect ratio to 4:3, the collisions boxes stay the same and objects can go off screen from the sides

[formal scarab]

@still tendon Look into this: https://www.youtube.com/watch?v=M7v1TGQnJ7I

That covers how to setup Cinemachine cameras to nicely follow along 2D and confine themselves to an area that shouldn't differ by screen ratio. If you want to prevent the character walking off too you just have to throw some colliders around the edge

[still tendon]

The game doesn't have a moving camera, so that doesn't really help me, but it was useful to watch still so thank you 🙂

[formal scarab]

Oh, ok 🙂 I guess I don't understand your description of what you're trying to do then

[tidal onyx]

Hello, so essentially I am trying to make an enemy in a side scroller walk and then turn around when they hit a wall. This is what I got so far does anyone know what is wrong with this code?

Right now the enmy just jitters in place atm

[hidden cypress]

@tidal onyx For one, you can just do movement = direction * speed * Time.deltaTime
Second, what happens if you replace translate with just altering the position manually?

[tidal onyx]

Would something like this work for changing the position manually?

this.transform.position = new Vector2(transform.position.x + 1, transform.position.y);

[hidden cypress]

You can just do transform.position += myVector

In your case transform.position += movement

You dont need this, the this is inherent when referring to stuff in the class scope

[tidal onyx]

Hmmm... I get the same result. Basically the game object just vibrates back and forth. I assume that is because the raycasts are hitting the collider too early?

[hidden cypress]

Do you have a rigidbody or anything else on it?

[tidal onyx]

Although I dont think the game object is not close enough to the collider to trigger it, so idk

Yeah I have a rigidbody

[hidden cypress]

Is gravity on?

[tidal onyx]

Here it is

[hidden cypress]

What happens if you set gravityScale to 0?

[tidal onyx]

I get the same thing

[hidden cypress]

if you remove the rigidbody wha happens?

[tidal onyx]

Unfortunetly the same result

[hidden cypress]

Wait actually, that if statement seems weird

Are you trying to say if one of the raycasts is over the side of the platform or something it flips?

You originally said when they hit a wall but you're raycasting down

[tidal onyx]

So they are raycasts on each side of the game object and yes I am intending for them to flip when they hit a wall. I'm using raycasts instead of OnCollisionEnter because the environment is a tilemap so it all has the same tilemap collider.

I see the issue you pointed out with the raycasts being .down, what should I change that to?

.right and .left?

[hidden cypress]

Yeah because right now its like youre checking if its grounded

Since both raycasts are pointed down im assuming its always triggering

[tidal onyx]

Ok, I got the game object to move! The only issue is, when the raycast touches the collider, that if statement gets caught in an endless loop. Is there any way to get around this?

[hidden cypress]

What do you mean by endless loop?

[tidal onyx]

So basically right now the gameobject moves, and when it encounters a wall it gets stuck there. What I think is happening is the raycast is colliding with the wall collider, starting the if loop, and turning around the game object, however since the raycast is still touching the collider when this happens, the if loop executes again and so on, going on forever

[hidden cypress]

Oh. Do

direction *= -1;
transform.position += direction;

multiplying by -1 is the same as scaling it

The reason its happening is because time.deltaTime is not consistent so its probably getting caught

[tidal onyx]

Something's wrong with the second line, I get an error

It says

[hidden cypress]

oh is it vector2 to 3?

[tidal onyx]

No everything should be vector2

[hidden cypress]

I mean is that the error?

Like invalid conversion or something

[tidal onyx]

It says the operator += is ambiguous of types vector2 and vector3

[hidden cypress]

transform.position += (Vector3)direction;

Do that

[tidal onyx]

Ayyy it works!

Thanks so much for your time, I really appreciate the help

[hidden cypress]

Yeah you cant add v2 and v3, adding (Vector3) in front converts the vector2 into a vector3

Since transform.position is always a v3

[blazing cave]

Need help with something; -;

Assuming I have a clock in the scene (whose hands are already running) if a bool becomes true, the minute hand should be "fired" in exactly the direction in which it is pointing.

How can I do that?

[oblique crown]

Hi, I'm probably asking a stupid question, but is there anyway to create more than one Rules Tile with the same tiles? Basically I have this tile: https://files.fm/u/3gzr8yxt3#/view/u7csgnyn8 and based on the dimension of the rectangle, I want to use part of it. I'm thinking I have to create different Rules Tile and use each one appropriately, correct?

[oblique crown]

Other question: can two tiles with the same rule coexist?

[potent iris]

Check if the bool is true and then add a force to the minute hand

[zealous topaz]

hey there. quick question here. I'm using a Tilemap and I have registered and rendered a few tiles through code. My problem is that the images are too large, I need to know how many pixels the tilemap draws per unit. How can I get this piece of information?

Unity 2020.3.2f1

Got it, it all depends on what value I give as pixelsPerUnit when I create the sprite

[hearty anvil]

Hi, I was just wondering how do you get an instance of a GameObject to reference itself in code. It's fine to do with GameObjects where they are the only ones with a certain tag but with enemy bullets for example I need it to reference the exact one I'm using and not the prefab or anything else.
Not sure if I'm making sense with this but it's pretty hard to explain 😓

[misty vine]

If you have a script on a prefab, when you instantiate that prefab, it creates a whole new GameObject and the script that runs is relative to that single instance of it.

[hearty anvil]

So would my option be to just set the GameObject to public and then drag and drop my prefab into that in the Inspector?

[misty vine]

That depends entirely on what you're actually trying to do

[hearty anvil]

I'm trying to access the SpriteRenderer and Transform components so I can alter them in code

[misty vine]

So you want to create a reference to the SpriteRenderer in your script, and either drag it in the inspector or use GetComponent<SpriteRenderer> in your Start() method.
Transform you can just call with the transform reference

[hearty anvil]

Can I change the scale of the sprite using the transform reference?

[dusty jolt]

hi, probably a stupid question but, is there a way i can read how much pressure is being applied to a Rigidbody, i can't seem to find anything helpfull online.

[snow willow]

Closest you can get is the impulse from any collisions:
https://docs.unity3d.com/ScriptReference/Collision-impulse.html

But of you're talking about fluid pressure or something Unity's physics engine doesn't simulate that

[dusty jolt]

thanks

i accidently put my scene to hexa in the tilemap. how do i change it

strg Z doesnt work

nvm

[edgy plover]

Hi guys I have this problem, I want to put a character but my world is a parallax that is always in motion, so it gets out of place and the effect is put on the sprite. I have more bug, does anyone know what I could do? I have no idea

[fast wolf]

Working on an isometric map, just followed a guide by Adam C Younis. My tiles with higher Z are drawing below tiles on the same grid space with lower Z values. Mode of tilemap renderer is set to individual, sort order is on top right.

[unborn pilot]

how do i make a script that will run some code if all the enemys in the layer is gone

[gray brook]

Do you have some kind of enemy factory that would be able to watch for that condition?

[high radish]

Hey I need some help regarding UI ordering in unity 2d. So we got a setup where there are platform gameobjects in the world and a canvas instantiated under it as a child, basically to make a setup where an object has a text attached to it, and the player character can climb over it.
The problem is that the UI appears over everything else; we don't want that, we want the text to stay behind the player character. I am not sure how to proceed on this one- should I make a single canvas for the entire scene and replace all the texts? mess with the layers in canvas/sprite renderer?

Here is a screenshot. The text should appear under the player character but over the dark brown box.

and the "canvas instantiated as a child of game object":

[snow willow]

Screen space UI will always draw over world space objects. Use a world space canvas or a second camera with screen space camera UI on the bottom camera and the 3d object on the top layer

[high radish]

can you elaborate on the second method? It seems like world space canvas is a bit too large

[high radish]

nvm, fixed the issue by just making an empty child and adding textmeshpro component to it (and adjusting sorting layer). thanks for the help!

[dim forge]

hi, i was hoping someone could help me with how i make the character animation only happen when they are moving? thanks!

[strange echo]

I'm currently trying to generate a checker board and I can't figure out why my color isn't generating properly. I'm getting this when the desired effect is just a normal-patterned checkerboard. Can anyone help?

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

public class Board : MonoBehaviour
{
    public GameObject mCellPrefab;

    public Cell[,] mAllCells = new Cell[8, 8];

    public void Create()
    {
        for(int y = 0; y < 8; y++)
        {
            for (int x = 0; x < 8; x++)
            {
                // Create Cell
                GameObject newCell = Instantiate(mCellPrefab, transform);

                // Position the Cell
                RectTransform rectTransform = newCell.GetComponent<RectTransform>();
                rectTransform.anchoredPosition = new Vector2((x * 100) + 50, (y * 100) + 50);

                // Setup
                mAllCells[x, y] = newCell.GetComponent<Cell>();
                mAllCells[x, y].Setup(new Vector2Int(x, y), this);
            }
        }

        for(int x = 0; x < 8; x += 2)
        {
            for(int y = 0; y < 8; y += 2)
            {
                // Offset every other line
                int offset = (y % 2 != 0) ? 0 : 1;
                int finalX = x + offset;

                // Color
                mAllCells[finalX, y].GetComponent<Image>().color = new Color32(230, 220, 187, 255);
            }
        }
   
``` This is the code I'm using to generate the board

And I highly doubt the problem lies in my Cell class but here's the code for that too ```cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Cell : MonoBehaviour
{
public Image mOutlineImage;

public Vector2Int mBoardPosition = Vector2Int.zero;

public Board mBoard = null;

public RectTransform mRectTransform = null;

public void Setup(Vector2Int newBoardPosition, Board newBoard)
{
    mBoardPosition = newBoardPosition;
    mBoard = newBoard;

    mRectTransform = GetComponent<RectTransform>();
}

}

Nevermind, I found the problem

My second nested for loop should've been y++ instead of y+=2

hey, i just wanted to adjust the hight of a coin in my game. But when i click on the coin the inspector just shows a preview:

but when i did this yyesterday it showed me the stuff with high and xyz

how do i get back to this inspector

[ruby karma]

I think you were looking at the sprite settings for the coin

[misty vine]

You've clicked on the sprite, not a game object that is using this sprite

[ruby karma]

or that

[signal storm]

you guyxs are angels

wait

its more less

[novel pewter]

Anyone figured out how to get Z Axis working properly on an Isometric tilemap with chunk rendering? I've set up sprite atlasing and set Trasparecy sort mode but that hasn't helped...

[signal storm]

how do i click on it as an object?

[novel pewter]

From the Hieracy widow, find the object you put your coin sprite on, then press that object to adjust the positioning with the inspector window

[signal storm]

this is what i see

when i click from hierarchy on object its the same

[signal storm]

still got the problem

anyone ideas?

[noble ivy]

hello, I have a question.

this should be 2D, but when you turn your player model, it changes the prespective a bit? or is it an ilusion haha

[narrow frigate]

its an illusion i believe

this is the second image rotated 180 in paint

[tidal onyx]

transform.rotation = new Vector2(transform.rotation.x, transform.rotation.y, 0);

Anything wrong with this line?

If there is, how do I go about changing the rotation/direction for something?

[snow willow]

Rotation is a Quaternion

Also Vector2 only has 2 components, did you mean Vector3?

If you want to set rotation as a Vector3 use transform.eulerAngles @tidal onyx

Same for reading it

[tidal onyx]

My game is top-down so I guess I meant vector 2

I only did 3 values because there were 3 in the inspector, my bad

[snow willow]

eulerAngles is a Vector3

You will have to use Vector3

If it's 2D most likely only the z axis rotation matters

[zealous topaz]

Hi there. Quick question: https://docs.unity3d.com/ScriptReference/GridLayout.CellToWorld.html

Does it return the center of the cell, or one of its corners?

[cyan yoke]

what would be the best way to have a drag to rotate system?

I've tried doing it myself, but the object just keeps spinning

[trim fjord]

I haven't been able to find a good answer through googling... I have a number of GameObjects with a BoxCollider2D each, and scripts with OnMouseDown functions. If these objects overlap, what decides which of them get the click?

Currently it seems that one of my objects that's the largest but also has a Order in layer of 0 whereas the other objects have 1, 2, or 3 gets the click event.

I read that changing the Z value of the GameObject's transform is one way to do this. Is this the recommended approach?

That doesn't seem to work though. Even setting the "wall" GameObject to Z = -1 makes it still get the OnMouseDown call instead of objects with a higher Z value in front of it

Ah, Z should be greater the further away it is, of course

[mild marsh]

How to freeze character in x axis?

[snow willow]

Depends

You using a dynamic rigidbody?

[mild marsh]

i'm using rigidbody 2d

[snow willow]

Is it dynamic? Are you moving it through velocity/forces?

[mild marsh]

Dynamic

[snow willow]

Then you can freeze the x position from the rigidbody component

Under constraints

[mild marsh]

Thx

[mild marsh]

I wish the character could still move around, but not to flip

[snow willow]

?

What does flipping have to do with freezing x axis motion

[left lotus]

You mean you want to freeze the rotation and not the position?

[sick heron]

RaycastHit2D hit = Physics2D.CircleCast(groundCheck.position, radius, Vector2.down, 1f, 8);
This doesn't hit anything, even though it should. All the vars are valid

[snow willow]

Your Layer Mask looks sus

Use
public LayerMask myMask;

Configure the Layers in the editor

And use that in your circle cast

If that's supposed to be layer 3 it's ok, if it's supposed to be layer 8 it's wrong

[sick heron]

@snow willow I tried putting in a string

but it's asking for an integer

[snow willow]

Use a LayerMask

Not string or Integer

[mellow sleet]

can someone tell me why its dosnt working? ps ignore the unknown script thats a other script.

[left lotus]

I'm guessing you have 2 scripts named LevelManager

Or 2 scripts each containing a class named LevelManager

[mellow sleet]

thats only one i think

[snow willow]

File name might not match it

[worn halo]

Im almost certain my code is right to make a gameobject destroy itself when it enters a trigger but nothing is happening do objects need a rigid body or a collider to work with triggers?

[snow willow]

• both objects need colliders
• at least one collider needs to be a trigger
• at least one object needs a Rigidbody (it can be kinematic)

[worn halo]

@snow willow Thankyou! The problem was that I didnt have a rigidbody on either objects

[worn halo]

Im trying to set a variable to a insantiated clones gameobject so that I can destroy one clone at a time and not the entire prefab and I am having trouble doing so.

I have tried putting the script on the prefab so that the instantiated objects might destroy themselves one at a time but its not working

[snow willow]

The Instantiate function returns a reference to the instantiated clone

So you can capture the reference in a variable there.

Having the script destroy itself should work as well.

assuming you have a way to trigger said destruction

[rare lake]

wait....

actually i know why nvm

[snow willow]

your last one is = should be ==

[still tendon]

hey, I am trying to make a raycast to detect if my character is at a ledge so that it can grab on to it, I already mad the raycast, what I am having trouble with is selecting only certain colliders for the raycast to detect, so to only have the edge colliders be detected by the raycast and trigger the animation, so how do I do that?
code:

//get raycast origin position
        shootRaycast = raycastOrigin.position;
        //get raycast direction
        raycastDirection = raycastOrigin.TransformDirection(Vector2.right);
        //raycast
        hangEdge = Physics2D.Raycast(shootRaycast, raycastDirection, 1f);
        //visualize raycast
        Debug.DrawRay(shootRaycast, raycastDirection);

[wispy sable]

(ah - figured it out, for some reason the parent had a -10z value)

[still tendon]

oh yeah, thats because if you spawn a gameobject it will sometimes spawn it in random weird locations

so always when creating a game object, especially in 2d games first make the location 0,0,0

[arctic stag]

you can use the layer mask to ignore objects on a certain layer. i think that is the only way to ignore certain objects https://docs.unity3d.com/ScriptReference/Physics.Raycast.html

[still tendon]

oh thanks, Ill try that

[subtle badger]

guys how can i make one block impossible to pass?

[abstract shore]

Like how?

[latent hazel]

Hey, so I am using the unity IDragHandler stuff to make certain objects drag and droppable, however I also wanted to be able to rotate an object 90 degrees when the player right clicks, but unfortunately that just starts a new drag. How do I write my code so the player can modify the object while dragging?

[wet nova]

Hi Guys, is this a good place to ask some simple questions regarding 2D stuff? I just started messing around with unity and have some questions for "setting up empty objects to be filled later" and getting components or parents of components 🙂

[tidal onyx]

Yep you can ask questions here

[wet nova]

Thats awesome! I'll try to figure out the stuff I dont get and all and write some questions later then 🙂 Thanks!

[wet nova]

Ok i got one: How can I change the Color of a children 2D Object Sprite from a Parents Script?

I find a lot of stuff with
Color parentColor = this.GetComponentInParent<Renderer>().material.color;
GetComponent<Renderer>().material.color = parentColor;
and so on but whenever I try something with the GetComponent Stuff it always fails and throws errors like
Evaluate request failed (Could not resolve type: Renderer).
Evaluate request failed (Unknown member: GetComponentsInChildren).
and so on, depending on which angle I try to tackle the stuff 😄

[rare lake]

Anyone know why I would get an error if I did public float mobStrMod = (mobStr + 10) / 2;

[still tendon]

what is the error message

[still tendon]

set the variable on Start

[still tendon]

do what the error says. it says } expected so put it

[craggy briar]

You cant assign the variable based on another variable when you declare it like that

[rare lake]

so how would I be able to do it 😮

[craggy briar]

Just declare it, and assign the value you want in Start like Hasan said

[rare lake]

I swear I did that exact thing and it didn't work, but it is now XD thanks guys

It's not even doing the math -.-

Doesn't seem to be running the Variables at all

Is this supposed to update with whatever i declare these variables to be?

[zealous topaz]

hey I need a short guidance. I want to draw a sprite, and some text, at the bottom left corner of the camera, and I want them to stay there even if the camera moves later on. How should I do that? thanks

[rare lake]

If you know how to make the text just make ur a child to the player and camera a child to the player

It*

[zealous topaz]

this is the tree so far, so what component should I create as a child of Battlefield?

[knotty barn]

@rare lake The initialization values are only used when the component is created, after that it uses the Unity serialized values.

[zealous topaz]

could somebody help me please?

[rare lake]

So I just do a void start() or something else for them?

[snow willow]

No.

[knotty barn]

Set the values in inspector if you want to have default values. Set them in Start or wherever if you want to override the serialized value

[rare lake]

Alright

[snow willow]

If you set the value in Start I can't see what the benefit of making them serialized at all is

[rare lake]

So what would be my best bet?

[snow willow]

whatever makes sense for you

[knotty barn]

You can use [NonSerialized] attribute to disable Unity's serialization of that field

[snow willow]

Or just make it private

[rare lake]

Well I’m trying to make it so the stats are dependent on level, which will match the player level so that the game scales to the player

[snow willow]

The relevant question is do you want to set values per instance in the inspector?

Or do you want to set them in code?

If it's the former, leave them public or private with [SerializeField]
If it's the latter, make them private or public with [NonSerialized]

[rare lake]

How do I make them NonSerialized

[snow willow]

private int mobLevel;

or

[NonSerialized]
public int mobLevel;

[rare lake]

Oh so just make them private?

[snow willow]

yes...

[rare lake]

Oh 🥴

Wouldn’t that make it so I can’t use it in a separate code for like player or something

[snow willow]

Then do:

[NonSerialized]
public int mobLevel;```

or, even better:

public int MobLevel { get; private set; }

[rare lake]

Noice, thanks

Then I can just do Debug.Log(mobLevel); if I wanna make sure it went through in the console right?

[snow willow]

of course

[rare lake]

Alright, just wanted to make sure I had the code right for it

Tbh that top one with the brackets looks cleaner 😂

[snow willow]

they do different things

[rare lake]

What’s the difference?

[snow willow]

the first one is just a public field with a special attribute on it to tell Unity not to serialize the field. The [Nonserialized] attribute is just a hint to Unity that says "don't serialize this"

The second one is a property. Properties allow you to carefully control access to variables in your script

See https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

[left lotus]

^ Yeah by default unity automatically serializes public fields, so you have to tell it not to

[rare lake]

Neat

[rare lake]

Something I did was creat an empty, name it player, drag the camera to it to make it a child of “player” once you start putting in the stuff for the character and everything the camera will follow the players movements. When you make the text object, however you do that, do the same thing and drag and drag it into the “player”

[zealous topaz]

thanks!

if I use

gameObject.transform.Translate(x, y, z);```

all of its children will be translated as well, if I understand you correctly

[ruby karma]

yes

if you move a parent, the child is always moved

[zealous nebula]

hello

So I am German and would have a problem with Unity because I want to make a start menu for my game, unfortunately I don't know my way around and so I watch videos and other things so that I can develop my game. Well that works quite well but my problem is that when I do this menu I have to create a new scene, but when I jump to the other scene the other one is simply deleted everything that was in there. I tested this before I do it on my real project but I don't know what to do next. Have you got an idea?

[ruby karma]

did you save the scenes ?

[zealous nebula]

omg how stupid i'm no wonder that doesn't work xD

Thanks alot @ruby karma

hello, it's me, for the 1637912748923178934 time!, i'm struggling a lot with this enemy AI stuff i try to implement, the problem is that the enemies yes, are targeting the player and instantiating bullets at the player BUT dont aim towards the player i guess the problem is in the way i stored the closestPlayer variable but im not sure

also, when a enemy shots, it transfers the player position to a vector2 called target but... is a completely mess!

How can I create gameObject and move it to vector2?

Vector2 cursorPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);

[lyric crag]

hey, Is there a way to check if there's a tile present on a tile grid or not?

like i have multiple tile objects considered as map layers as a child of grid so is there a way to check if tile is present on that grid?

[vocal condor]

I would guess it best done during collision detection else you're stuck with possibly searching the hierarchy for the unknown.

[forest cave]

tilemap.hasTile

or

tilemap.getTile if you want a specific tilemap

remember to do using UnityEngine.Tilemaps;

[lyric crag]

thank you 🙂

this helped

Good Morning,
Why would't an light source NOT cast shadows on an object while using the ShadowCast2D ?

I think I got it, I need to enable shadows on the lighting source ;P

[forest cave]

how do i do ontriggerenter2d with a tilemap because when i have this it only counts the first tile i walk onto instead of all

[vale bobcat]

sorry, can you please tell me how to also drop the code?

[still tendon]

If not, I've created some numbers: can't I import them directly into Unity to create a font?

[left lotus]

A font file is a bit different than just being an image

You can use your images as a Sprite or Image object, and combine them to make the illusion they're acting as a font, but not necessarily as a font without converting it

[still tendon]

To be more precise, with the same font style, my white background is not there:

[left lotus]

Oh gotcha. Your white is being imported as alpha somehow

They're exactly the same files as what you just posted above? The alpha seems correct on the numbers above

[still tendon]

In fact, the numbers with the white background were created by me. Simply because in my game, with the font, there is no white inside the numbers

[left lotus]

Wait I don't get you. The image files you uploaded above are the same as the ones you're using in your game, or they are not?

[still tendon]

No, they are not the same. To put it simply:

• In my game (without the white background) it's an installed font (.ttf)

• The numbers with the white background, it's me who created it (.png)

I created these numbers to try to put them in the place of the font because currently, they don't have a white background, here it is

[left lotus]

Ok understood, yeah you'll need to convert your images to a font, which isn't totally simple

Fonts don't really use pixels for things the way an image does

Because a font needs to be able to zoom up/down by a lot and stay crisp

So a font file is actually a description of the lines and paths that make up a "glyph", or character

There are tools to convert a .png to a .ttf that you can try

But because the formats are so different, pixels vs vectors, tools don't always do a good job converting

[still tendon]

then, I don't know if there is another solution to have a font with a white background as I want, maybe with the Text Mesh Pro

[left lotus]

You'll have to find a font that is designed the way you want, or you can modify the font in a program made for editing fonts like FontForge

[still tendon]

FrontForge is free? ah I know otherwise. I also have this:

[left lotus]

Know otherwise? Yeah it's free and open source

[still tendon]

well, I thought of putting the font in white and adding a black outline but the outline is blurred, I had forgotten

[left lotus]

In fontforge?

[still tendon]

no in Unity

and you can add colour to font forge, can't you? so I edit my figure and add white to it

[rare lake]

I didn’t see a UI channel so ima ask here, for EXP for example as a variable could I set up the UI to have a border than have the bars horizontal transform be linked to the EXP variable to “fill” if that makes sense

[still tendon]

I am trying to make my character in Unity 2D be able to hang onto an edge until I press a button and it will either climb up or fall down depending on what you press, but until you press something it just hangs there, and to make sure it doesnt fall down I made the gravityscale 0 and the velocity in both axis 0 as well, once you press W it will go back to normal and pull you up, but the problem is that it would make the velocity 0 and gravity scale 0 on each frame, I need it to happen only on the first frame that it detects that you are on a ledge (using a raycast), every frame after that it doesnt need to update it until I either press W or S feel free to ask any clarifying questions because I am not very good at explaining things

this is the first script(I wrote this in two scripts to keep it a bit more organized):

// name of the raycast
     if (hangEdge)
             {
     
                 if (Input.GetKey(KeyCode.W))
                 {
     
                     rb.gravityScale = 5;
     
                     transform.position = Vector3.Lerp(transform.position, myPosition[posIndex], lerpTime * Time.deltaTime);
                     t = Mathf.Lerp(t, 1f, lerpTime * Time.deltaTime);
     
                     if (t > 0.9f)
                     {
     
                         t = 0f;
                         posIndex++;
                         posIndex = (posIndex >= lengtht) ? 0 : posIndex;
     
                     }
     
                 }
             }

second script:

if (hangEdge) {

         //get rigidbody component(rb is the name of a rigidbody2D variable)
         rb.GetComponent<Rigidbody2D>();
         if (myFunctionCalled == false)
         {
             //change velocity on both x and y axis to 0(essentially tell player to stop moving)
             rb.velocity = new Vector2(0, 0);
             //set the gravity on this object(the player) to 0
             rb.gravityScale = 0;
             myFunctionCalled = true;
         }
     }
     else 
     {
         
         //set gravity on this object(the player) to 5
         rb.gravityScale = 5;
     }

I also made my own attempt at solving the problem, to no avail

pls ping me if you have an answer

also thanks in advance

[bright fjord]

@still tendon
You could freeze your rigidbody upon touching the ledge, and unfreeze when you get input
(rigidbody.constraints)

[still tendon]

alright thanks, Ill try that

[ivory spear]

I checked aome tutorials on yt, as a beginner, I dont understand one simple thing, why do people use "vector3" in 2d games as opposed to "vector2"?

In example, transform object to x,y they used transform new vector 3 (xx,yy) id think ignoring z(2d), it would be overall better to use vector2?
Or did i simply misunderstood vector3/2 in general? (And the number is not related to dimensions)

[bright fjord]

I think it's because you can't assign a Vector2 to transform.position, but not too sure about that

[left lotus]

There are 2 reasons. In some cases, the way you mentioned is correct. It's better to use a Vector2 if you really don't need the z value

But like wtch28 says, transform.position is actually a Vector3

Even in a 2d game, Unity does it in 3d but with the Z value fixed to 0

[ivory spear]

Ah, good, thanks :)

[left lotus]

You can actually create different visual layers in a "2d" game this way, by moving them along the Z

[ivory spear]

On the same note, if im spawnong something on top of something else, that is in fixed position, is it better to use instantizate(or whatever its called) with vector xy values or with object to spawn o top of ? Not sure what the differences/advantages are

Example, i have a square in fixed position, and in script i wantt o spawn object on it, i can instanciate it using the circle, or, sinfe it is fixed, x,y vector on the circle, if that makes sense

[left lotus]

If you use a Vector3, it goes to that position and is not a child of anything. If you use an object (transform) it will make it a child of that object

[ivory spear]

Is that so?
Thanks

So
Instanciate (go1, go2)
Makes go1 child of go2
Instanciate (go1, vector3)
Moves go1 to poaition of vector3

[still tendon]

from what I learned, unity does gameobjects in 3d even if the game is in 2d, but if you have a 2d game it will do physics calculations in 2d

[left lotus]

Correct. Keep in mind, being a child of an object means you're in the same position as it

So they both move it to the position

But one makes it a child

[ivory spear]

@left lotus thanks a lot, makes more sense now

It now makes sense why my object was rotated on wrong axis when i ritated my circle on x instrad of y, and when i scaled my circle the sprite scaled too

I fixed that by scaling the circle in prefab and then when i dragged my prefab to scene it was scale 1 1 1 again, so it worked, but ill try to refrain from doing it in the future, as it seems to add more work

Hey unity lovers! was hoping someone here might be able to suggest a decent tutorial for programmatic isometric tilemap generation, text or video doesn't matter I just can't seem to find much on the subject.

Any help is much appreciated!

[coral walrus]

Hi all -- relative noob to Unity here posting for first time. I'm working on an app that has
a static grid I want to display (the camera won't be moving around). I want it to look good on different devices, but I have an issue where due to the camera, some of the lines are distorted depending on the device viewing it. [here]: https://pasteboard.co/JWhZ1uE.png is the original image, [here]: https://pasteboard.co/JWi2jZm.png is an example where it is slightly distorted. Right now I'm not particularly worried about scaling properly, I am just trying to understand how to display an image without any distortion across devices (expecting that on a device with 2x the pixels vs another similar sized device, it'll be 1/2 the physical size). I am also curious if there are any really good tutorials out there dealing with 2d / pixel perfect rendering / UI elements. It looks like pixel perfect might do what I want, but in the little playing with it I've done, my UI elements are very distorted -- text just doesn't look good when I'm using pixel perfect.

Thanks much for any pointers 🙂

[coral walrus]

So I realized I posted a wall of text there. A simpler question that would help me greatly is just this: Is there a way to have a setup that will display an image on my target device pixel for pixel the way the image exists in the original file?

[abstract olive]

Have you tried Unity's pixel perfect camera package?

[coral walrus]

I've played with it a little bit, but haven't found any great tutorials for it either. If there is a good one you're aware of, I'd be happy to go through it.

I'll investigate it more, thanks 🙂

[abstract olive]

@west trellis No crossposting, please.

[abstract olive]

All I recall is Unity having a blog on how to set it up, but I've never used it myself. Have a look for that blog post.

[coral walrus]

oh sorry

im still very new at this sorry if im being too annoying

[oak forge]

So I have two triggers set up on an enemy and player game object. I am trying to make a simple system where the player can punch the enemy and knock them back a small distance and have the same happen in reverse. However, because of how triggers work when a punch occurs both triggers are activated on the players and script and the enemies script. This causes an unintended effect where the knockback is applied to both objects instead of just the one being punched. Is there anything I can do about this or I need to look at a different way of activating the knockback.

[wintry dirge]

Has anybody seen ScreenPointToRay giving incorrect results when using a pixel perfect camera?
It works when game view is maximized, but not when just docked in an editor window.

How to move objects around the room?

with a simple move script probally

[viral finch]

Does anyone know how to ignore physics2D collision between objects with the same tag?

I tried using the Physics2D.IgnoreCollision in a OnCollisionEnter2D but it doesnt seem to work

    {
        if (collision.collider.CompareTag("Spike"))
        {
            Physics2D.IgnoreCollision(collision.collider, GetComponent<Collider2D>());
        }
    } ```

This is the code im using

Basically im planning to make an enemy that'll shoot out spikes in a radial directions, and i want those spikes to not collide with each other once they are instantiated.

[viral finch]

Nvm i got it working

[zealous topaz]

hey, I created a BoxCollider2D through code:

        gameObject.AddComponent<BoxCollider2D>();
        BoxCollider2D boxCollider = gameObject.GetComponent<BoxCollider2D>();
        boxCollider.size = new Vector2(cam.rect.width, cam.rect.height);

where cam is a Camera component. I made it have the same width and height as my camera. Now, how do I make it have the same center, since BoxCollider2D.center is deprecated?

[zealous topaz]

anybody here know what the offset represents?

[snow willow]

Offset would be the local space offset from the transform position

[storm coral]

how can i disable the rigidbody2d and collider of an object in-code?

[snow willow]

so the actual center would be ```cs
Vector3 centerInWorldSpace = transform.TransformPoint(boxCollider.offset);

[storm coral]

pls?

[snow willow]

Colliders can be directly enabled/disabledx with the enabled property

Rigidbdoy has to either be destroyed or set body type to kinematic

[storm coral]

ok

thanks

oh one more thing

would setting the gravityScale of a rigidbody make it not affected by gravity at all?

[snow willow]

If you set it to 0, then it will not be affected by the global gravity setting

[storm coral]

ok thank

[zealous topaz]

sorry, I'm still a beginner and I've been reading this over and over and I still don't understand why applying TransformPoint to the offset would give you the center (world) coordinates. I would have thought that it would give you the world coordinates of the gameobject + Vector2(offset.x, offset.y)

[snow willow]

because the offset is a position in local space

TransformPoint converts a position in local space to a position in world space

that's all there is to it

[zealous topaz]

yes, I agree with that, but:

[zealous topaz]

that's not the local coordinates of the center, is it?

[snow willow]

anyway - I think if you're just trying to align this collider to the camera, why deal with offset at all? Just let the offset stay at 0 and set the position of the collider x/y to the same as the camera

[snow willow]

offset is the local coordinates of the center of the box. It's relative to the Transform's pivot location

[zealous topaz]

wow, I had no idea. It's written nowhere, as far as I've searched. Thanks

[zealous topaz]

so you mean, something like that:

gameObject.transform.SetPositionAndRotation(new Vector3(cam.transform.position.x, cam.transform.position.y, 0f), new Quaternion(0f, 0f, 0f, 0f));

where gameobject is the object having the boxcollided2d as a component

[snow willow]

something like that but just set the position, no need to set rotation (btw new Quaternion(0, 0, 0, 0) is an invalid quaternion)

transform.position = new Vector3(cam.transform.position.x, cam.transform.position.y, 0f);

If you want to set rotation too it would be like:
transform.rotation = Quaternion.identity;

[zealous topaz]

setPosition doesn't exist, and I've had errors with doing transform.position = , it was my understanding that I was changing a copy of transform.position rather than changing it directly

[snow willow]

setting position changes it directly

the thing you had a problem with was probably something like:

transform.position.y = 5f;

^ that you cannot do

but you can set the whole Vector3 at once

no issue

[zealous topaz]

ok thanks

long story short, the following:

        gameObject.AddComponent<BoxCollider2D>();
        BoxCollider2D boxCollider = gameObject.GetComponent<BoxCollider2D>();
        boxCollider.size = new Vector2(cam.rect.width, cam.rect.height);
        gameObject.transform.position = new Vector3(cam.transform.position.x, cam.transform.position.y, 0f);

will make a boxcollider exactly where the camera is, which will allow me to use OnMouseDrag for my script component

[worn narwhal]

Hey, so i am a beginner and i am working on a small game project. I have a problem and i feel like i am missing a simple solution.
i have a player object and another gameobject.
when the player presses space the game object is destroyed and replaced with another object. the UI interface reflects an additional point for picking up the object. I would like it so that the player can only hold one object at a time.

right now my problem is that my player can continue to interact with the other objects even though it has one object counted already. i would like the player to be unable to interact with the other objects until it has removed that object from the count

my player has this code implemented

private Text bagCounter;

public int bagAmount;

private void Start()
{
bagAmount = 0;

}

void Update()
{

bagCounter.text = "BagCounter: " + bagAmount;

}

I cant seem to put all the code on here but you get the jist

[sullen wadi]

zcoord0fMouse = Camera.main.WorldToScreenPoint(transform.position).z;
mouse_offset = transform.position - mouseWorldPos();
How can I remake this code in 2D?

[hearty anvil]

I'm very confused by something and not sure how to go about explaining it

I'm trying to have my boss object create emitters that also fire bullets. The script that controls emitters and the script that controls the boss both inherit from the same script where this bit of code comes from which creates the emitters to start with. What happens is the emitter successfully retrieves all of these values except for the location and rotation. They emit bullets but they don't move when they're supposed to. What I found the reason to be is because the emission script finds instBulletEmitter (this variable was declared at the start of the parent script) to be null.

I had trouble destroying this object before I changed it to read GameObject.Destroy(gameObject)
which is where I later learned the script doesn't have a value for instBulletEmitter. I've created objects in this way using similar functions to the one above before so I'm not sure why it's acting up now. I should also mention that this was working before but I can't pinpoint when it stopped working so I'm not sure what I did to cause it to break.

I had suspicions it had something to do with being inherited but I'm not so sure. I'm all out of ideas

[sullen wadi]

Debug.Log("OnPointerDown");
no work
Why is nothing displayed in the console?

[snow willow]

Either you have logs disabled or that code is not running

[sullen wadi]

but how to enable logs?

[snow willow]

They're enabled by default but top right of console window are 3 small toggles

One for normal logs, one for warnings, one for errors

[woven lynx]

i am still a bit confused about when to use scriptable objects currently i have created instances of playable characters that all share the same set of abilities so i'm using the scriptables for that but i was also considering using scriptable objects for enemies that share the same code is that a good way to go? or should scriptables be more for inventries etc.. ?

and do i keep all the animations code within that or seperate that out?

[snow willow]

I like to think of ScriptableObject as just like some static data holders that can be created, referenced, and modified from the Unity Editor.

You can use them for other stuff but that's the main way I use them

[sullen wadi]

https://www.youtube.com/watch?v=BGr-7GZJNXg&t=1s&ab_channel=CodeMonkey

did everything as per the lesson and nothing works and the game does not give errors

[snow willow]

"nothing works" isn't a particularly useful hint

[woven lynx]

ok thanks @snow willow was just reading online another guy who only uses them for data not functions unless it's something trivial and have other scripts use the data is this what you would recommend?

[sullen wadi]

Even the console in the unit does not work for me for some reason

public class DragObject : MonoBehaviour, IPointerDownHandler
{

public void OnPointerDown(PointerEventData eventData)
{
    Debug.Log("OnPointerDown");
}

}

I created a script and added it to the object

[woven lynx]

i didnt think multiple inheritence was a thing in c#?

[snow willow]

Yeah wouldn't recommend them for nontrivial behavior coding

[snow willow]

It's not, that's an interface

[woven lynx]

ah 🙂

[snow willow]

Do you have a Collider2D on the object?
An event system in the scene?
An inputModule?
A physicsRaycaster2D on the camera?

[snow willow]

So no

No Collider2D

You need all 4 of the things I listed for that to work

[hearty anvil]

Not to rush or anything but is there any solution on my thing or do I need to provide more information?

[arctic wren]

hey guys... I got a GameObject whose OnMouseEnter gets called twice every time point on it... thing is it only has one collider... anyone encountered the same problem ?

[snow willow]

Does it have any children with Colliders?

[arctic wren]

@snow willow just figured that shit out... I had a class which inherited from another one and I was calling Awake from the inherited class which somehow overrode the parent's class Awake where some important stuff was happening

[hazy bridge]

waht does this mean?

[abstract olive]

You're calling something on line 20 of EnemyFollow which hasn't been assigned.

[hazy bridge]

Do you know what it could be?

[snow willow]

gotta be target is null

[plush dome]

I've been following a code Monkey tutorial for a top down shooter and don't know what to do here, it just says there is no definition of it even though it's at the top

when i do that this happens

i need some help with my 2d platformer
i want it so when I hit W, my player goes through a door and goes to a different scene. but what if I want to go back?
for ex: player spawns at bed, he goes outside and back, after loading the scene he will always be at the bed

[vocal condor]

What's the question? What have you tried? What works? What doesn't? etc.

[sweet nest]

I solved it it was just that i forgot to check "Used By Composite" in the TilemapCollider

[mellow sleet]

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

public class LevelManager : MonoBehaviour
{
   
    public GameObject pauseMenu;

    private void Start()
    {
        pauseMenu.SetActive (false);
    }

    public void TooglePauseMenu()
    {
           pauseMenu.SetActive(!pauseMenu.activeSelf);
    }


        public void ToMenu()
        {
          SceneManager.LoadScene ("MainMenu");
        }
        
}

[still tendon]

Does anyone know how I can set a 2 second delay when I instantiate my items? Like wait 2 seconds and then the items spawn

[mellow sleet]

why is my script not working?

[still tendon]

Why doesnt this flip the player ? When he goes left he should face left but he doesnt

Nvm i fixed it

[runic pawn]

im experiencing something very odd

im making a chess engine and to generate the board and pieces i use a few loops

i use one big loop for every chessboard cell with a big switch statement that determines which piece should go where

however, it seems as if unity gives up the loop about halfway through and just restarts the entire function, resulting in an infinite loop

what the hell could be going on

i probably messed up somehow but i dont see why it would do the entire Start function again lol

im so confused, it stops halfway through my loop and then the start function starts again

[vocal condor]

Seeing code would likely allow others to better help you diagnose the situation.

[runic pawn]

alright but it's quite a lot and im not sure if people are willing to take the time to through it all and understand it

so i'll ask something different i suppose

how can i check if my scene is somehow being restarted? (causing my function to be abruptly halted and causing the start function to keep looping)

like the only reason the Start function would get called again is if the scene somehow reset

[still tendon]

Add a Debug.log that only sends a message in the first frame, and if it sends more then once then the scene or code is restarting somehow

can somebody help me

public class RocketControl : MonoBehaviour
{
    public Transform player;
    public float angle;
    Vector2 CurrentDirection;

    {
        Rigidbody = gameObject.GetComponent<Rigidbody2D>();
    }
    void Update()
    {
        angle = player.rotation.x+90;
        CurrentDirection = new Vector2(Mathf.Cos(angle), Mathf.Sin(angle));
        CurrentDirection.Normalize();
        if (EngineRunning)
        {
            Rigidbody.AddForce(CurrentDirection * EngineThrust);
        }
    }

i am making a rocket simulator

and this happes with this code:

if i dont add 90 to the angle, this happens:

[runic pawn]

good idea, thanks

[vocal condor]

Did you save? Physics should be handled in FixedUpdate. Are there missing code you are not showing us?

[quick jackal]

oh

[vocal condor]

player.rotation isn't Euler and likely not what you're thinking.

[quick jackal]

the same still happens

[vocal condor]

So are you not showing us code or is this the complete class?

What're you doing with angle? (Implies you may be doing other stuff you aren't informing us of)

[quick jackal]

this is literally the entire class

and for some reason the thrust is being applied in a constant direction, no matter the rotation

[vocal condor]

Well angle isn't what you think it is.

So the direction is completely off.

[quick jackal]

bruuh what is it then?

i need to acces Z rotation

[vocal condor]

Rotation is a Quaternion not Euler

angle = player.rotation.x+90; would give you some unknown result.

It has x, y, z and w components but they are not Euler values.

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

Rotation is a Quaternion: https://docs.unity3d.com/ScriptReference/Transform-rotation.html

[quick jackal]

man

[vocal condor]

For simplicity first use a static direction of Vector2.up

[quick jackal]

yeah but the whole point of this is to apply the thrust im poining in

[vocal condor]

public class RocketControl : MonoBehaviour
{
    public Transform player;
    public float angle;
    Vector2 CurrentDirection;
    public Rigidbody2D Rigidbody;
    public bool EngineRunning = false;
    public float EngineThrust = 0f;
    private float EngineMaxThrust = 100.0f;
    public float EngineThrustPrc = 0f;
    void Start()
    {
        Rigidbody = gameObject.GetComponent<Rigidbody2D>();
    }
    void Update()
    {
    }
    void FixedUpdate()
    {
        if (EngineRunning)
        {
            Rigidbody.AddForce(Vector2.up * EngineThrust);
        }
    }
}

[vocal condor]

That float value angle isn't what you think it is.

You likely want it's Euler representation.

[quick jackal]

yes

[vocal condor]

Use the euler angle property.

Then access the specific component you need

[quick jackal]

so Transform.EulerAngles.z?

[vocal condor]

Assuming you're referring to the instance of Transform (transform) it would be transform.eulerAngles.

[quick jackal]

aand it still does weird things

[vocal condor]

What's the current code?

With simply Rigidbody.AddForce(Vector2.up * EngineThrust); does it do the proper action?

[quick jackal]

with Rigidbody does it use internal coordinates or global?

[vocal condor]

They're using forces and not setting position directly; physics.

[quick jackal]

void Update()
    {
        angle = player.rotation.eulerAngles.z+90;
        CurrentDirection = new Vector2(Mathf.Cos(angle), Mathf.Sin(angle));
        CurrentDirection.Normalize();
    }```

thats the current main method

not sending anything else bc it has not changed

[vocal condor]

Alright I've got to go but just lastly want to mention that mathf cosine is expecting a value in randians

Whereas I believe you're assuming it's in degrees.

There should be conversion in the mathf utilities https://docs.unity3d.com/ScriptReference/Mathf.html

[quick jackal]

k added angle = angle * Mathf.Deg2Rad;

[vocal condor]

And you would then apply the direction to force rather than vector2 up

I've got to go, good luck.

[quick jackal]

thank you very much

Guys, please tell me a script that will move the decor like in Sims 2d

[still tendon]

        audioSrc = GetComponent<AudioSource>();
        
    }

    // Update is called once per frame
    void Update()
    {
        if (rb.velocity.x != 0)
        {
            isMoving = true;

        yield return new WaitForSeconds(0.5f);

    }

need help

my sound is happening constantly

[snow willow]

You are suffering from a misunderstanding of the workings of coroutines

in more ways than one

Coroutine walkingCoroutine;

// Update is called once per frame
void Update()
{
    if (rb.velocity.x != 0)
    {
        isMoving = true;
    }
    else
        isMoving = false;

    if (isMoving)
    { 
        if (walkingCoroutine == null) 
        {
            walkingCoroutine = StartCoroutine(Walk());
        }
    }
    else if (walkingCoroutine != null) 
    {
        StopCoroutine(walkingCoroutine);
        walkingCoroutine = null;
    }
}

IEnumerator Walk()
{
    while (true) {
        int index = Random.Range(0, 3);
        audioSrc.PlayOneShot(clip[1]);
        yield return new WaitForSeconds(0.5f);
    }
}``` @still tendon

[gleaming moss]

Hey, I also have a small question.
In the Screenshot you see two 2D collider.
The big one is to track if the player is close to the enemy...

But the Problem is:
That a bullet that I made, dedects the big collider as an hitbox... so its to easy to hit the enemys...

How can I say the Bullet, that only the small collider is the right?

PS: Sorry for my bad english

I'm also sorry if this is the wrong channel

[fickle prairie]

@gleaming moss in the unity menu, go to edit > project settings > physics 2d. At the bottom there is a section, "Layer Collision Matrix". You can set up different layers and say whether they interact with each other or not. Then put the large collider on a gameobject that has a layer that doesn't interact with the bullet

[gleaming moss]

Youre missing a semicolon. You need to connect your visual studio to Unity as well.

[violet timber]

How do I do that?

[abstract olive]

Instructions are pinned in #💻┃code-beginner

And where? Lol

Your script is short, figure it out.
