why AssetDatabase.LoadAssetAtPath<Sprite>("Assets\\Textures\\plane01.png") not work?

i have check several times the path

[hollow crown]

Does it not have a file extension?

[remote moth]

?

[hollow crown]

#854851968446365696

[remote moth]

it has

[remote moth]

sry i forogt

[hollow crown]

Right, so now that's in your code does it work

[remote moth]

in the code i has png

[hollow crown]

Also, I'd use forward slashes

[remote moth]

i have it write new in discord the line

[hollow crown]

https://docs.unity3d.com/ScriptReference/AssetDatabase.LoadAssetAtPath.html

ALL asset names and paths in Unity use forward slashes, even on Windows.

[remote moth]

don't fix it

[hollow crown]

Also, note that AssetDatabase is Editor-only, so if you're not making an editor script you're using the wrong method

[remote moth]

what methode is better?

[hollow crown]

Serialized References, Addressables, the Resources folder.

[remote moth]

mean you Resources.Load?

[sudden dagger]

Thanks, I'll look into that a bit more. The knockback "bug" or issue happens when I'm not moving as well would that still be an issue of transform vs. physics?

[lusty olive]

I want to make it so tiles on the 'breakable' tilemap get destroyed upon being hit, how could I make this?

I found the answer to my question,

[stoic moon]

I'm following the brackeys tutorial for a* pathfinding, and it works well, exept that the movement is really floaty and feels like more of a plane or car pathfinding than a walking enemy. I'm pretty confident with unity, but I'm still not that good with enemy ai, so please excuse any obvious errors in my code: ```
if(path == null)
{
return;
}

    if(currentWayPoint >= path.vectorPath.Count || Vector2.Distance(rb.position,target.position) <= attackDistance)
    {
        reachedEnd = true;
        return;
    }
    else
    {
        reachedEnd = false;
    }
    Vector2 direction = ((Vector2)path.vectorPath[currentWayPoint] - rb.position).normalized;
    Vector2 force = direction * speed * Time.deltaTime;

    if (!reachedEnd) rb.AddForce(force);
    else rb.velocity = Vector2.zero;

    float distance = Vector2.Distance(rb.position, path.vectorPath[currentWayPoint]);
    if(distance < nextWaypointDistace)
    {
        currentWayPoint++;
    }```

this is being run in a fixedUpdate method

I dont understand fully the a* pathfinding system either, so sorry if I missed any obvious solutions

[paper dune]

check out sebastian leagues a* pathfinding tutorial on youtube

its great

[stoic moon]

Oh hey that dude is really good

his videos are so relaxing

Ok i'll do that

I tried using this for my moving to make it a bit less floaty: rb.velocity = Vector2.MoveTowards(rb.position, (Vector2)path.vectorPath[currentWayPoint], 10); but all it did was yeet my enemy into the stratosphere in the opposite direction?

[timid hound]

How do you know it’s the stratosphere

Did you debug.log it?

[stoic moon]

sorry I meant its just going super fast in a single direction

[timid hound]

Ok

Maybe put the waypoints closer to the ground?

Then the character won’t float

[stoic moon]

sorry I'm using 2d

[timid hound]

Or is it not possible

[stoic moon]

it seems to be lowering towards this number -7.629395E-06 when I start it

[timid hound]

Hmm

But it didn’t do that before you changed the code

[stoic moon]

yea using addforce worked fine

[timid hound]

Make it be transform.position instead of Rn.velocity

RB

[snow willow]

Why are you setting the velocity to a position?

That's kinda nonsensical

[timid hound]

I said it first

Yay

[stoic moon]

doing this transform.position = Vector2.MoveTowards(rb.position, ((Vector2)path.vectorPath[currentWayPoint].normalized), speed); just teleports my object to the end for some reason?

and then after a bit it just gets stuck in one spot

[still tendon]

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

public class basicMovement : MonoBehaviour{

    public Animator animator;

    void Update()
    {
        

        Vector3 movement = new Vector3(Input.GetAxis("Horizontal"),Input.GetAxis("Vertical"), 0.0f);

        animator.SetFloat("Horizontal", movement.x);
        animator.SetFloat("Vertical", movement.y);
        animator.SetFloat("Magnitude", movement.magnitude);

        transform.position = transform.position = movement * Time.deltaTime;
    }
}

I am using this code with on my character. I get no errors but my character automatically moves down?

[stoic moon]

getting rid of the .normalised seems to stop the thing getting stuck, but it still teleports directly to the end point

[snow willow]

Why's there an extra transform.position = transform.position in there

Anyway it will move down if movement.y is negative I suppose

[still tendon]

thats my bad lmao

i fixed it from falling now, but now my character doesnt move but just does the animation

[stoic moon]

Managed to fix my code, but now when my player is behind a corner the enemy ignores the nodes and just moves towards the player and gets stuck on the wall? here's the script: ```using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Pathfinding;

public class FollowEnemy : MonoBehaviour
{
public Transform target;
public float sightRadius;
public float attackDistance = 1;
public float speed = 200;
public float nextWaypointDistace = 3;

Path path;
int currentWayPoint = 0;
bool reachedEnd = false;
Seeker seeker;
Rigidbody2D rb;

// Start is called before the first frame update
void Start()
{
    seeker = GetComponent<Seeker>();
    rb = GetComponent<Rigidbody2D>();

    InvokeRepeating("UpdatePath", 0f, .5f);
}

private void UpdatePath()
{
    if (seeker.IsDone())
    {
        seeker.StartPath(rb.position, target.position, OnPathComplete);
    }
}

void OnPathComplete(Path p)
{
    if (!p.error)
    {
        path = p;
        currentWayPoint = 0;
    }
}

// Update is called once per frame
void FixedUpdate()
{
    if(path == null)
    {
        return;
    }
    if(currentWayPoint >= path.vectorPath.Count)
    {
        reachedEnd = true;
        return;
    }
    else
    {
        reachedEnd = false;
    }
    Vector2 direction = ((Vector2)path.vectorPath[currentWayPoint] - rb.position).normalized;
    Vector2 force = direction * speed * Time.deltaTime;

    rb.AddForce(force);

    float distance = Vector2.Distance(rb.position, path.vectorPath[currentWayPoint]);
    if(distance < nextWaypointDistace)
    {
        currentWayPoint++;
    }
}

}

It didnt do it in the brackeys video got this from

you know what screw this its way to late for my brain to work properly

[pastel sage]

Hello guys! I was wondering if anyone had any idea how to make Platform Effector 2D work with tilemaps. I mean, it works but it only works for a single platform. I cannot draw multiple platforms on a single tilemap or the effector simply won't work as it should

this is what I'm trying to accomplish

[stoic moon]

It does work just fine, just if you're flipping the platform effector to drop through it flips every platform in the scene

[pastel sage]

I havent implemented the dropdown yet

like the bottom platform in the webm

it's just not working

which is weird because it does collide from the sides

and if I paint more platforms, the effector goes to the middle of it all

oh I see what's going on

those are too close to each other

so the player's collider is still interacting with the top arc's collider and makes every single one passable

[pastel sage]

nvm, got it fixed. changed the tiles colliders to a single pixel tall one

and the effector only interacts with a small collider at the feet of the character

Hey guys i have a question, how do i make a raycast in 2 different direction and use it for the same function

[covert whale]

make your two raycasts, then you can do
if(hit1 || hit2)

[topaz dew]

Hello, I just started studying unity last week and there's a bug where my character gets stuck when jumping. Can someone tell me what's the problem and how to fix it?

Movement Script: https://hastebin.com/nuzaxorunu.csharp
Video: https://youtu.be/v3C0sxGMs2o

[civic knot]

Probably because you don't reset the animation parameter. You only ever set it to true
anim.SetBool("isJump", true);

[lament roost]

Hello,
Anyone knows how to use the Pixel Perfect Camera with Lightweight RP ?

[blazing mica]

Hi, so as I am concern, there is two ways to flip a sprite direction

1st : change +-ve of the gameobject
2nd : access the SpriteRenderer and use the Flip method

so generally which way is more preferable, or does it not matter whatsoever?

[blazing mica]

try having your Animator window and Game window side by side, see how your animation states run

[civic knot]

2nd because it avoids messing with everything else. It just renders the sprite inverted.

[topaz dew]

I tried to add anim.SetBool("isJump", false); and it doesn't animate the jump animation anymore

[civic knot]

where?

[civic knot]

Yeah, that's not the right place. It will set it to false on the next frame. You need to set it to false when the character becomes grounded.

[topaz dew]

do i need to create a new function

[civic knot]

Up to you. You don't have to. You could just put all of your code in update directly.

[hollow crown]

it looks kinda underhighlighted too. If you're not getting errors underlined in red, #854851968446365696 has the instructions for configuring VS.

[white cairn]

Hi, I am trying to patch some text rendering code as follows in a unity game public static void Postfix(TooltipBrickEntityHeaderView __instance) { //__instance.m_MainTitle.text = "hi"; __instance.m_MainTitle.color = (Color32)Color.green; __instance.m_MainTitle.overrideColorTags = true; __instance.m_MainTitle.outlineColor = (Color32)Color.magenta; __instance.m_MainTitle.outlineWidth = 5; } My code can change the color easily to this obnoxious test color. However it doesn't let me add an outline. Can someone please help me understand what I am missing?

Here is a tooltip for the type of m_MainTitle

[topaz dew]

thank you, it works now

[covert whale]

your ide is most likely not configured, look at #854851968446365696 for how to do it

[topaz dew]

okayy thanks

[foggy horizon]

Is there a way to get SpriteRenderer's quad vertex, and then change its vertex color?

[tranquil tulip]

Hi there! By chance are there any people working with ProCamera2D?

[brittle smelt]

Can someone help me? i cant seem to diagnose the problem with this code, the gameobject that is attached to this code should flip around if encountered a wall or a hole in the ground but it doesnt wanna flip instead it got stuck

[covert whale]

could you do a Debug.DrawRay of your raycast to see that it's going in the right place

[brittle smelt]

where should i put the drawray function?

[covert whale]

right underneath your raycast

give it the same arguments for the raycast

[brittle smelt]

@covert whale https://streamable.com/dt2zld

[covert whale]

i think the issue is that even after you flip the character the transform is moved to the right
and this could be because you're using Vector2.right which is the world space for right, not transform.right which is relative to the transform

so try changing to transform.right to see if that fixes it

and additionally change any other Vector2.direction to transform.direction

[bleak elk]

Does <sprite>.bounds.center return the centre coordinates (as a Vector3) of the given sprite regardless of its pivot point (example: if its pivot point is at the bottom centre, does it return the coordinates of the bottom centre or the exact centre?) or is it completely different?

[distant oracle]

So hello I need some help

[abstract olive]

#854851968446365696

[distant oracle]

Hello I am recently having some questions

[grand coral]

ok so say the questions lmao

[distant oracle]

I was hum writing sry

xD

I want to do this

but the circle can be moveable depending on the position of a gameobject

is this possible?

I can do a sprite renderer so I can have a dark overlay but can I do a moveable hole on it somehow?

I want to do this so I can do a tutorial to my game btw

IF possible please DM me with answer

[abstract olive]

You would have to build a shader for this. It wouldn't be complicated, but also not easily explained quickly.

[distant oracle]

Any docs for that?

I have no idea what is a shader or how to use/do them xD.

[abstract olive]

There are no Unity docs for creating gameplay features, no. Only for the API.

If you have no idea what a shader is, then you have a big hill ahead of you.

Alternatively, if the hole doesn't have to animate around, you could just create different images with the hole baked in, and switch between them during the tutorial.

[distant oracle]

Hum I prefer to learn how to use shadows I guess ;-

[grand coral]

why can't he just use a spritemask

can you not do multiply or other blend modes with a spritemask?

[abstract olive]

Possibly? I haven't used it much. It looks like there's this:
https://docs.unity3d.com/ScriptReference/SpriteMaskInteraction.VisibleOutsideMask.html

[grand coral]

yeah that's what i was thinking of, i think that would work with a semi-transparent image

and much simpler than a shader (although i always look for opportunities to write cool shaders bc it's fun lol)

[still tendon]

Hello i have a pretty simple movement and animation script which works great but when i press w and d at the same time my character moves super fast diagonally? Any help/solution.

[fleet remnant]

well... its not that hard to figure out

you probably apply force for each key you press

so when you press 2 keys at the same time

you apply twice the force

or you dont apply force but just translate more units per second so it seems as if its faster

we cant know without seeing your script but basically, calculate the direction based on the inputs you have and only THEN add force / move in that direction

[remote moth]

i want to know when the mouse not touch a object

[grand coral]

the exact moment it stops touching, or at any given time query whether or not it's touching?

[grave fox]

How do I limit transform.Translate movement to 2 decimal places?

[snow willow]

what do you mean by this?

are you trying to round the resulting position?

Or limit the position to be within some range?

[grave fox]

Okay, basically I'm trying to achieve pixel perfect movement. I have background elements which parallax however when they reset on the x axis I get a nasty seam with some visual glitching. I'm using the Pixel Perfect camera component set to 640x480 and the grid units set to 0.01. I believe that the visual glitching is due to Unity translating the background elements in units which aren't 'pixel perfect'. I've been searching for hours for a solution and can't find a simple way to fix it.

[snow willow]

well one issue you're going to have is that 0.01 is not a number that is possible to represent in binary

it's an infinite repeating expansion

sort of like how 1/3 in base 10 is 0.3333333 repeating

0.01 in binary is like 0.0110110110110101 and so on

[grave fox]

PPU is set to 100 currently

So setting PPU to 1 maybe so movement is in integers?

[snow willow]

or maybe try grid units that are representable in binary

maybe 0.0125

[grave fox]

Currently 0.01 translates to 1 pixel... If I change the grid units I'm going to have to adjust the PPU to match

That's why I'm thinking PPU 1, grid units 1 (1 unit = 1 pixel)

Camera of 640 pixels wide would also be 640 units wide

All I want to do is increment the translation by 1 pixel at a time

[distant oracle]

How can I change the size of a mask?

but not of the sprite

[grand coral]

if you change the size of a sprite that has a sprite mask component on it, it should change the size of the mask

[distant oracle]

Hum yeah

but hum

I am so confused rn

but I want to keep the sprite with a specific size

but make hum a hole on it with a small size

[grand coral]

?

you want to change the size of the mask but keep the sprite that it's masking the same size right?

[distant oracle]

nvm nvm nvm

Im just being dumb

I just made a sprite mask in another gameobject

so I can make a circle in the rectangle sprite

and now it has exacly what I wanted thx 🙂

[grand coral]

cool

[distant oracle]

:=: xD

[bleak elk]

Looks like the message got lost (common in a server with many members I am not even angry about it). Just wanted to mention it again by just replying on it and ask whether or not you guys know about it.

[civic knot]

Bounds are generic. There are bounds for different renderers and colliders, so no, they don't take into account config specific to the object they're on.

[tawny tendon]

I am making a 2D game on a tilemap, and because I want to constrain movement to the grid, I am not simulating physics. Instead, I manually check for collisions before allowing the player (or other items on the map) to move onto a tile.

The problem I am running into is that when I move an object by directly setting transform.position, its collision boundaries do not seem to update right away. In other words, after updating the position and "occupying" a tile, another object that uses Physics2D.BoxCast to check whether the tile is occupied will not detect a collision.

So sometimes I get two objects moving onto the same tile at once, which should never be allowed, since the objects should collide with each other, and the first to occupy the tile should prevent the other from entering.

I have taken steps to verify that this is not just a "race condition." It seems as though updating the position of an object does not cause any other object to detect collisions with its new location until a later update cycle.

I'm guessing this is known behavior and not a bug, but I'm wondering if anyone can point me to documentation that will help me understand what to expect with regards to when collision boundaries get updated.

[timid hound]

I’m pretty sure that collisions get processed in FixedUpdate, so if you set the position in update, it won’t get processed till next fixeduodate

[tawny tendon]

Ah, that's an interesting thought. I am doing everything directly in Update, so I will see if moving my collisions checks to FixedUpdate resolves the problem. Thanks.

And now that I know the answer, it is easy to find a bunch of similar answers with a google search.

[subtle vessel]

there's a setting in the project settings (in physics) called somethign like "autosync transforms"

turning it on should fix your problem, I think

https://docs.unity3d.com/ScriptReference/Physics2D-autoSyncTransforms.html

or https://docs.unity3d.com/ScriptReference/Physics-autoSyncTransforms.html

though it sounds like you're using 2D physics, so the first one

[tawny tendon]

Oh, that's perfect. The documentation for that setting also matches what I was experiencing.

When set to false, synchronization only occurs prior to the physics simulation step during the Fixed Update.

So even if I moved it to FixedUpdate, things might get out of sync if I am updating multiple transforms, since the synchronization happens just once per fixed update otherwise.

[amber shard]

hm. I was hoping to do some simplistic but dynamic shapes for a 2d sprite game. chaining lines of various thickness, arcs, that type of thing. Is there a way aside from gui-hacking for this?

[subtle vessel]

Are you familiar with the LineRenderer component?

also, the Shapes asset is very well suited to that kind of thing. https://assetstore.unity.com/packages/tools/particles-effects/shapes-173167

[amber shard]

Hm. I like it, though I don't know how to sort through Sprite Rendering and Mesh Rendering... in terms of sorting and layering the drawing

Will explore it more for sure

[brittle smelt]

Can someone help me? how do i use this to make an if statement, like "if distance from a is less than 3 then do this"

[still tendon]

hello, when i press (for example) a and w my character goes diagonally but faster then just pressing a, any help?

[jolly narwhal]

if(dist < 3) { do this }

[jolly narwhal]

Need to see the code

[still tendon]

alright

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

public class PlayerMovement : MonoBehaviour
{

    public float moveSpeed = 5f;
    
    public Rigidbody2D rb;
    public Animator animator;

    Vector2 movement;

    // Update is called once per frame
    void Update()
    {
        movement.x = Input.GetAxisRaw("Horizontal");
        movement.y = Input.GetAxisRaw("Vertical");

        animator.SetFloat("Horizontal", movement.x);
        animator.SetFloat("Vertical", movement.y);
        animator.SetFloat("Speed", movement.sqrMagnitude);

        if(Input.GetAxisRaw("Horizontal")==1 || Input.GetAxisRaw("Horizontal")== -1 || Input.GetAxisRaw("Vertical")==1 || Input.GetAxisRaw("Vertical") == -1)
        {
            animator.SetFloat("LastHorizontal", Input.GetAxisRaw("Horizontal"));
            animator.SetFloat("LastVertical", Input.GetAxisRaw("Vertical"));
        }
        
    }

    void FixedUpdate()
    {
        rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);
    }



}

[jolly narwhal]

You set the speed to sqrMagnitude which is about 1.4 if both x and y movements are 1

if you want the speed to be always the same then set the speed to 1

[still tendon]

what should i change to 1?

[jolly narwhal]

the speed

[still tendon]

are you referring to the moveSpeed?

[jolly narwhal]

no, the one that uses sqrMagnitude

animator.SetFloat("Speed", movement.sqrMagnitude);

[still tendon]

ah i think i get it.

[jolly narwhal]

and set movevent to movement.normalized to get a distance that's always one in FixedUpdate

[still tendon]

do i have to add

movement.normalized

to FixedUpdate?

[jolly narwhal]

yes, for example

[still tendon]

when i add movement.normalized; i get an error "Assets\scripting\PlayerMovement.cs(37,9): error CS0201: Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement"

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

public class PlayerMovement : MonoBehaviour
{

    public float moveSpeed = 5f;
    
    public Rigidbody2D rb;
    public Animator animator;

    Vector2 movement;

    // Update is called once per frame
    void Update()
    {
        movement.x = Input.GetAxisRaw("Horizontal");
        movement.y = Input.GetAxisRaw("Vertical");

        animator.SetFloat("Horizontal", movement.x);
        animator.SetFloat("Vertical", movement.y);
        animator.SetFloat("Speed", movement.sqrMagnitude);

        if(Input.GetAxisRaw("Horizontal")==1 || Input.GetAxisRaw("Horizontal")== -1 || Input.GetAxisRaw("Vertical")==1 || Input.GetAxisRaw("Vertical") == -1)
        {
            animator.SetFloat("LastHorizontal", Input.GetAxisRaw("Horizontal"));
            animator.SetFloat("LastVertical", Input.GetAxisRaw("Vertical"));
        }
        
    }

    void FixedUpdate()
    {
        rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);

        movement.normalized;

      
    }



}

or did i do it wrong cause this is all new for me

[jolly narwhal]

no, replace movement with movement.normalized

[still tendon]

so for movement.x should i change that aswell

[jolly narwhal]

no only for that one line in FixedUpdate

[still tendon]

ohhhhh

thank you so much lol i had no idea what to do.

[still tendon]

hello is there away i could make an attack delay because i can just click my attack button very fast and the animation just keeps on resetting.

Hey is there a function that record if a gameobject is in front or behind another gameobject?

[still tendon]

my bad

[haughty pollen]

Hi! I’m watching a tutorial on c# and using unity and I’m supposed to use : private BoxCollider2D boxCollider; and on the tutorial guy’s screen the BoxCollider2D has a colour on it but mine doesn’t. So I’m thinking it that it doesn’t register? When I’m going to playtest in Unity it says “All compiler errors have to be fixed before you can enter playmode!” I don’t know what’s wrong, I seem to write everything just like in the tutorial.

[compact knoll]

set up your IDE using the configuration steps linked in #854851968446365696

also compiler errors will be in the console in the unity editor, if you have errors in the console you won't be able to test until you fix those errors

[haughty pollen]

Ok, thank you.

[haughty pollen]

I'm sorry, but where is the workloads tab? Or the modify button? There isn't any other buttons except open, new or projects.

Or am I supposed to do it in the Unity Hub?

[compact knoll]

that's in the Visual Studio Community installer. Did you install visual studio separately or did you install it with the unity editor when you downloaded it through the hub?

[haughty pollen]

I installed it separately.

[compact knoll]

ah in that case you'll need to run the installer again to add the workloads

[haughty pollen]

Is it simpler to install it in the Unity Hub?

[lean estuary]

Yes, it installs all dependencies and configures itself

[haughty pollen]

Alright, I'll try that.

[lean estuary]

Don't forget to remove copies first, it may mess with it

[haughty pollen]

Course

Great! Thank you. And sorry for the hassle.

[livid hill]

Can someone help me with some transform math?
Basically I have this heirarchy:

| PlayerBody (Rigidbody2D - Dynamic):
|--> BoxingGlove (Rigidbody2D - Kinematic)

When the player presses a button I want the boxing glove to shoot out and come back like a punch. I'm controlling the glove movement via a script (lerp to destination, lerp back to start) but the problem I am facing is that I can't figure out how to use Rigidbody2D.MovePosition in terms of local position so the glove always stays in position relative to the player.

I.e. If the player is moving how do I keep a good starting position reference for handling my lerps.

[covert whale]

you could try transform.TransformPoint to convert the position you want the glove to move from local to world space
https://docs.unity3d.com/ScriptReference/Transform.TransformPoint.html

do all your lerping calculations in local space, then when you want to actually move use transform point

[livid hill]

Still don't quite have it working but I'm headed in the right direction now. Thanks.

[livid hill]

Got it working! Two things I found out along the way:

• You have to use the parent transform for TransformPoint to work properly (kinda obvious but I overlooked it at first)
• Apparently Rigidbody2D.MovePosition will not work if the rigidbody is a child of another moving rigidbody. I don't really need the physics checks that MovePosition offers since my child rigidbody is just a trigger so I am just applying the position directly to the transform which does work.

[covert whale]

nice

[haughty pollen]

Sorry, one more thing. When I download the Visual Studio for Mac it says Completed with errors. And Install failed. Any way to fix this? I've tried looking it up online, nothing seems to work.

[compact knoll]

if you are using visual studio for mac then just install it normally. the tools for unity are included on the mac version (as you would have seen had you switched to the mac version instructions)

[haughty pollen]

Alright! And again, sorry for the hassle.

[bleak elk]

I've got a problem. I have a gameobject that I want to spin. However, its sprite's pivot is not in the centre (done like that on purpose for other reasons). I know that I can make it a child of an Empty GameObject and then spin the parent (the Empty GameObject). Is there a way to find the co-ordinates of the exact centre of the gameobject's sprite? Or even the distance between the sprite's pivot and the sprite's actual centre?

[vague meadow]

my sprite is split into several layers. on my movement code, all the parts are moving individually at different speeds even though their position in the world is identical. any clue?

[storm coral]

Does anyone have any idea how I would go about making collideable shadows?

[vague meadow]

separate object parented with its own collider is the easiest method

or create it by script addComponent and set transform

[storm coral]

yeah but how would I get it to conform to the shape of the shadow

[vague meadow]

polygoncollider

then press the button in the inspector that looks like a point selection diagram

that will open the editor for the polygoncollider in the scene view

assuming the shadows shape never changes and is known before hand

[storm coral]

therin lies the problem

the changing shape

i need to have the collider move to wherever the shadow moves

[tame turret]

do you have a screenshot how the shadows look like?

[vague meadow]

u shud be able to animate it per frame

unless u r generating it procedurally

in which that is more advanced

[storm coral]

im using the 2d lighting shadows

either that or making my own

[vague meadow]

i came to a similar issue myself

i saw that u can tie variables to each frame in the animator

thats the first potential solution

the second is to have multiple shadows and deactivate the right one

[storm coral]

yeah but i cant predict every possible location of the light

[vague meadow]

the light is generated by unity

we are talking about collider shapes moving to suit the frame

unfortunately i dont know more on that sorry

[storm coral]

i mean the light source

the player will carry the light around and place it down where they need

[tame turret]

do you have multiple light sources that determine the shadow colliders?

[storm coral]

just one

[tame turret]

and you you need point or shape collision?

[storm coral]

idk

its a platformer

what would be really good is if i could just tell the player, collide with anything onscreen that is black

[tame turret]

yes

you can always make a custom collider that looks up collisions in a utility texture

render your occluders manually with a special material into a render texture and use that as data-source for the collision lookup

[storm coral]

sorry idk what that means...

im somewhat new

[tame turret]

right

[compact knoll]

what you are attempting is not exactly simple in any way. Give these threads a read to better understand what it is that you are doing (and some possible solutions)
https://forum.unity.com/threads/3d-shadows-collider.824499/
https://answers.unity.com/questions/1739021/make-shadow-interactive-1.html

they are technically for 3d, but the concepts discussed would still apply for the most part

[storm coral]

thanks!

Ps. can anyone tell me why this: https://paste.mod.gg/qrskfyqiobyb/0 end up like:

[snow willow]

1. It's pink because your linerenderer doesn't have a valid material.
2. Some of the lines are weird because DrawLine(vertex, unNormdir, Color.black, Mathf.Infinity); is erroneously using a direction vector as a position.

Also new Vector2(transform.position.x, transform.position.y); is unecessarily verbose - you can just use (Vector2)transform.position

[balmy pebble]

hey does anyone know how to make sprites overlay another sprite when its y level is lower than the bottom of the other sprite in a 2d top down game

[tame turret]

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

[balmy pebble]

let me try that question again, i want the player to be behind the object when its towards the top of the sprite, and when the player is at the bottom of a sprite it is ontop, thios updates during runtime. Also the sprite building is accually a tile which makes it a bit harder

depending on player position the player orders itself, how do i do this

also for these images i manually changed the sorting layer to show what i want

[balmy pebble]

thanks Anikki ill be using your tip with prefabs in tile palettes to do this

[fleet remnant]

you can use pick like lets say the top 3 tiles of the sprite to be one sorting group, and the 3 bottom ones to be another sorting group, depending on which tilemap you put them

if its a prefab tho idk how you could do that

[balmy pebble]

yea its all good thanks, i found an alternitive thats working ok, i just cant use tiles for the houses, i was getting lazy lol

[neat flame]

Hi guys, i want to make my player sprite blink between red and normal color to show the invincible state after getting hit. After 3 seconds, the player would go back to normal. I got the 3 seconds then back to normal thing, but i can't get the player sprite to flash between 2 color in that 3 seconds duration. What should i do?
https://pastebin.com/hTiqGpLw

[thin bear]

@neat flame use an animation instead of this hard-coded approach

[neat flame]

Yeah, the other guy in Beginner channel also telling me the same thing. I haven't even touch Animation up till now, lol. Guess it's time!

[thin bear]

👌

[craggy kite]

Really depends on your case, if you will have loads of animation styles like this, go for animation. If you just have simple flashes, you can still code it and go on animation later if it does not feed your visual needs

[neat flame]

Yeah, i've found a way to hard code it for now. I'm learning Unity now so i will touch on Animation sooner or later. Which is not my strong point, lol. I like working with code more than UI as i'm working as an Automation scripter :p

[craggy kite]

I mean you can have quite good procedural animations with code, but thats another topic 😉 So do you need any help with the code or did you figure it out? 🙂

[neat flame]

Thanks 🙂 But yeah, i got it figured out. A bit hacky tho.

[craggy kite]

I am sure using ienumerator cant hold that many ways of hacking colors 😉

[neat flame]

Here's my work-around, not very efficient i'd say.

https://pastebin.com/CzG6NGmT

[craggy kite]

Looks fine too me. not sure whats not efficient about it, such a small piece of code 🙂

just be sure to StopAllCoroutines otherwise you overlap ienumerators on every call of that function

[neat flame]

Gotcha, i'll do that!

Hi! I’m having trouble writing this line of code: transform.Translate(moveDelta * Time.deltaTime); I’m on a MacBook and I cannot make the multiplication symbol right and I don’t find anything on google. Anyone?

[compact knoll]

What do you mean you can't make the multiplication symbol right?

[haughty pollen]

It’s not like, on the top. But in the middle. Then the “Time” line isn’t in the right colour? If that makes any sense.

[compact knoll]

if you aren't getting syntax highlighting then you need to configure your IDE using the steps linked in #854851968446365696

[haughty pollen]

I did!

Oh what

What happened?

Oh

It wasn’t connected for some reason.

Nevermind then!

[exotic cradle]

What do you do when your button doesn't change colors when highlighted or pressed during runtime?
I have 'Interactable' checked off
I have another button that successfully darkens when clicked
I don't know what I'm missing

[snow willow]

Possibly another UI element is blocking it

Try looking at the inspector/preview window of your event system while the games running to see if it's detecting a different object

[exotic cradle]

I don't detect anything rendered in front the button, but 100% certain I'm using this tool right

[neat hollow]

im trying to make a base builder game, how do i store a "room" ?

i have the grid set up and player can build walls

how do i detect which grids is inside these connected set of walls ?, so then i could mark those grids as room 1

[bleak elk]

Any ideas?

[snow willow]

floodfill graph algorithms like Breadth-first search to find all connected squares

[neat hollow]

@snow willow thank you, its hard when i dont know the term i have to search 🙂

[covert whale]

you could call sprite.bounds.extents and subtract/add that to the pivot to get the center, if sprite.bounds.center doesn't return what you want

Hey guys, do any of you know how to fix this error: SceneView rotation is fixed to identity when in 2D mode. This will be an error in future versions of Unity.
UnityEditor.SceneView:OnEnable ()

I have no clue what's causing it, it returns a warning every time I touch something

[chrome snow]

Would anyone know what could be my issue:

1. I as a player run into a wall which doesn't allow me to pass. The character and the main GO of the player stays in the correct position(Correct)
2. When I try to attack as the player the spawned object position is waay off it sort of moves when I collide with my wall. The spawned position should be the same as where the player is located. (Issue)

Player Setup: has a network transform,rigidbody + rigidbody network,the movement and attack scripts are on the root player gameobject.
Spawned object: is spawned at the location of the root player gameobject

How is such sorcery possible?? 😄

Hey friends, I am generating multiple tilemaps and setting them next to each other for a platformer game. I'd like to be able to combine two tilemaps together. Any thoughts on how I might go about doing this?

Nevermind! Figured it out. I was forgetting to account for the x and y position of the other tilemaps and was just overwriting each tilemap which the one that comes after it.

[still tendon]

I'm trying to make sure a player character can pass through a collider until they've crossed it, and then they must land.

For this, I've made two layers, PlatformOpen and PlatformCaptured for such a platform and I've made a Player layer. What I'm trying to do is:

PlayerController.cs

        private void Start()
        {
            print(LayerMask.LayerToName(gameObject.layer));
            Physics2D.IgnoreLayerCollision(gameObject.layer, character.PlatformOpenLayer, ignore: true);
        }

Platform.cs

        [SerializeField, Layer] private int platformCapturedLayer = 7;
        [SerializeField, Layer] private int playerLayer = 8;

        private void OnCollisionExit2D(Collision2D other)
        {
            if (other.gameObject.layer == playerLayer)
            {
                gameObject.layer = platformCapturedLayer;
            }
        }

I've checked the layer values obviously, but it doesn't seem to work yet. Am I using IgnoreLayerCollision right?

I think I've mistaken some functionality here: ignoring collisions may even mean not being able to detect them. Perhaps I should use the IsTrigger property.

That didn't work. How else is it possible to preserve the player's rigidbody motion while still allowing to ignore collisions...

By which I mean it should still fire the Unity callbacks but I'll not have the character bounce back.

[still tendon]

Solved it by a crude bounds check.

Hey, Guys ,I am trying to make 2d Android Games and i have a problem with background, how to scale background same as 2d orthographic camera

Thanks before i hope you understand my problem

[covert whale]

if you always want the background to be the same as the camera's size, and if you don't want it to move, then you can make a canvas, set it to camera space, put it a layer underneath everything else, and add an image that stretches fully, then make your image the background

[fossil bluff]

Hi folks. As part of a bigger project, I'm recreating a Pacman game using Tilemaps. After a LOT of trial/error, I almost have a working model - except for some reason I cannot seem to have the player sprite flush against left or down facing walls. I think it has something to do with the wall detection code:

    {
        Vector3Int gridposition = walls.WorldToCell(transform.position + (Vector3)direction);

        if (walls.HasTile(gridposition))
        {
            return true;
        }
        return false;

    }```

It seems X+1 and Y+1 tile locations are fine, but X-1 and Y-1 are somehow exactly one cell away from the player sprite - but I cannot see why, or how to correct the alignment. Any tips would be welcome 😄

[covert whale]

could you debug.log gridposition to make sure it's the right one?

[fossil bluff]

I will double check that indeed.

hmm so it is working - however I think this is an issue with world to grid location - say the left side wall is at cell X=-9, logically we want munchyboy to stop at X=-8 - however he's actually stopping at X-7.1

On the other side, if the wall is at X=8, he is stopping at X=7

Must be a rounding issue, I do hate working with float to int

[prisma ocean]

Say I wanted to make a collider for the line renderer that represents the asteroid field, should I generate a bunch of circle colliders and get their positions in the same way that I got the positions for the ellipse line renderer?

[covert whale]

what do you need colliders on the belt for?

depending on how accurate you need to be it could be a single polygon collider or a series of edge colliders

[plush coyote]

^

although if you are only going to use it as a trigger, there are probably better ways of determining if you are in the belt (using radius from center, if its a circle)

Well not "better," just alternate

depends what you want / need it for

this is my enemy ai code, and i want it to go to the player and push them, but when it comes very close to the player it just stops, how can i fix that?

[hollow siren]

do they have rigid bodys?

@still tendon

[still tendon]

Yes they do

@hollow siren

i really need this fixed, because it's the main point of the game. so if anyone could help me out would be amazing

[hollow siren]

the problem is the if statement

[still tendon]

How can i fix it?

[hollow siren]

when it's near the player it doesn't do the comand any more

so it doesn't move

[still tendon]

and how can i fix that?

i'm really new to this

just tryin to do the best out of it

[hollow siren]

I would use velocity instead of transform.Translate

myRigidbody.velocity = new Vector3(...);

can I fix your code real quick?

[still tendon]

Yeah that i would appreciate

[hollow siren]

do they have Rigidbody or Rigidbody2D?

[still tendon]

i'm very confused rn so if you can help me fix the code would be nice

rigidbody2d

[hollow siren]

      myRigidBody.velocity = (target.position - transform.position).normalized * speed;
    }

  }

}

sorry

messed up

now it sould work

[still tendon]

now it just rotates against where my character is but not moves

[hollow siren]

ok

I can fix that

give me a second

[still tendon]

ty

[hollow siren]

how about now?

[still tendon]

it says transform does not exist

line 27 transform does not exist in current context

[hollow siren]

weird... every game object should have a transform

[ruby karma]

transform

not tranform

[still tendon]

omg im blind

[hollow siren]

ups typo

[still tendon]

still goes up to me it feels like we're touching but it doesn't push me

he comes this close

and just

stands there

[hollow siren]

is it because you are pushing the other way?

[still tendon]

no i stand still

[hollow siren]

show me both rigidbodys in the inspector

[still tendon]

this is player

this is enemy

[hollow siren]

so... I am quite confused

does it move to the player at least?

and then it stops?

[still tendon]

yeah

it moves to player then stops / cant push it

dont know which one it is

[hollow siren]

can I see the player code?

[still tendon]

yeah

    }

  }
}

[hollow siren]

I am afraid that the problem is here

since you are forcing the volocity to be 0 when you are not touching comands

[still tendon]

so what should i do

i don't want it to fall onto its side and not be able to do anything

[hollow siren]

ok I'm thinking...

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

public class PlayerMovement : MonoBehaviour {

    public float jumpSpeed = 8f;
    private float direction = 0f;

        }

    }
}

try this

[still tendon]

yess

now

it pusehes a litte bit

but then stops

[hollow siren]

hahahahaha

[still tendon]

looks like it doesn't have enough power

[vocal condor]

I think that if statement about direction isn't necessary.

[still tendon]

and + now it flies (the enemy)

[hollow siren]

let him code as he understands it hahaha

[hollow siren]

put the enemy code as it was before, your code was better

[still tendon]

using System.Collections;

public class EnemyAi : MonoBehaviour
{

  public Transform target;//set target from inspector instead of looking in Update
  public float speed = 3f;


  void Start()
  {

  }

  void Update()
  {

    //rotate to look at the player
    transform.LookAt(target.position);
    transform.Rotate(new Vector3(0, -90, 0), Space.Self);//correcting the original rotation


    //move towards the player
    if (Vector3.Distance(transform.position, target.position) > 1f)
    {//move if distance from target is greater than 1
      transform.Translate(new Vector3(speed * Time.deltaTime, 0, 0));
    }

  }

}

this?

[vocal condor]

When direction is not greater than zero or not less than zero, it's definitely zero; implying the third player.velocity = new Vector2(0f, player.velocity.y) - direction.x is zero.

[hollow siren]

try, I never used transform.Translate, that is why I said to change it

but my code, I noticed it ignores the gravity

[still tendon]

it doesn't fly anymore, walks torwards me but doesn't push

[hollow siren]

oh ok

go back sorry

[vocal condor]

Are you moving with rigid body or transform?

[hollow siren]

I was courious

[still tendon]

rigidbody i think

[vocal condor]

Transform is a teleport and will not trigger physics detection.

[hollow siren]

I know, it was a test

it's using rigid body

[hollow siren]

like this

[still tendon]

i went back to your code

what now?

[hollow siren]

the problem is that it ignores the gravity

[still tendon]

is there anyway we can add more power to the ai, so it can push harder haha

[hollow siren]

add more velocity

[still tendon]

o ok

[hollow siren]

• more speed

[still tendon]

but then the gravity is problem

[hollow siren]

using UnityEngine;
using System.Collections;

public class EnemyAi : MonoBehaviour {

    public Transform target;//set target from inspector instead of looking in Update
    public float speed = 3f;

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

    void Update() {

        //rotate to look at the player
        transform.LookAt(target.position);
        transform.Rotate(new Vector3(0, -90, 0), Space.Self);//correcting the original rotation


        //move towards the player
        if (Vector3.Distance(transform.position, target.position) > 1f) {//move if distance from target is greater than 1
            Vector2 velocity = new Vector2(target.position.x - transform.position.x, 0).normalized * speed;
            velocity.y = myRigidBody.velocity.y;
            myRigidBody.velocity = velocity ;
        }

    }

}

how about now?

[still tendon]

cannot convert from 'UnityEngine.Vector3' to 'float'

[hollow siren]

oh I'm sorry

try now

[still tendon]

still flies

[hollow siren]

try now

[still tendon]

now it flies a little and gets sky rocketed somewhere

just dissapears completely

[hollow siren]

I just changed it

[still tendon]

Yeah way better now

now it doesn't fly, just spins a little weird and falls alot

but works as it should

[hollow siren]

I'm sorry, it's difficult not being able to try the code I am sending you

not having the project

[still tendon]

Yeah but you're still helping me, i've gotten a better way now

even at higher speed than the player, and if i stand still

the enemy doesn't have enough power to push them

just a little (more and more for how much speed it has) but i dont want the enemy to be usain bold either

[hollow siren]

that is because most of the speed is going in the gravity

since it's an acceleration and not a velocity

ok I get it

[still tendon]

adding more mass helps, but it still gives like 1 big push then just stops

until i do something back

[hollow siren]

your if statement

do you need it?

[still tendon]

which one

[hollow siren]

or do you want to always go to the player

if (Vector3.Distance(transform.position, target.position) > 1f)

[still tendon]

Not Always maybe, but most of the time as it's a sumo game ihs

so i want the enemy to try push me off

[hollow siren]

when it gets near the speed drops since the player is pushing too

[still tendon]

no but even if i stand still, it stops pushing until i push it a little then it gives again a big push ( with more mass )

[hollow siren]

but you don't want that it's velocity is stoped when it's near the player right?

try getting rid of that if statement

[still tendon]

I want it to keep pushing, and when i figure out the pushing part then i'll try to add more stuff to the game, like that it can jump to avoid death etc

but now i worry about it just actually pushing and trying to win ( push me off)

[hollow siren]

give them the same speed and remove the if statement

and same mass

[still tendon]

trying

wayyyyy bettter

not it's actually hard for me

it doesnt stop now

but now if i jump, and my character ends up ontop of the enemy, neither i can jump or get of him, neither the enemy can move and is just under me

is there a code that can say that when i'm on top it makes me slip of or sum?

[hollow siren]

taht is because your jump code has the condition that it has to be touching the ground

you can fix that your self

[still tendon]

Yes i know, but i don't want it to jump forever, so it has to be grounded

[hollow siren]

maybe you can say that if you are touching the enemy you can still jump

[still tendon]

oh thanks

i'll try

[hollow siren]

I have to go now

I really hoped I helped, I am afraid I confused you more than anything

[still tendon]

Have a nice day bro, nah you helped me out now i just gotta polish the code a bit

[hollow siren]

you could also probably look in to some FSM states

so you can switch between your enemy rushing to you, bouncing back, and every thing that you want

and keep me updated on your game, it's interesting

[still tendon]

Alright Thanks

[coral tusk]

@still tendon if you are using a layer mask when checking for the ground, you could include the enemy's layer mask in the check, and you would be able to use them just like the ground?

then you could walk and jump on them and even use them as platforms if they dead maybe

[still tendon]

Yeah but the problem is

when i jump on the player i'm stuck forever, i did use the enemy as layer

but when i jump and move to the side it jus follows under me while still laying

so i never get of them even if i jump because they're still under me

but either way i just turned of it's rotation, but the player and enemy just keep pushing eachoter forever as one of them slowly goes to its death, and i can't jump over or anything to make it more fun because the enemy just keeps pushing and following you

so thinking of adding a delay or sum after some time it's stops or gets tired same with the player

[spare coyote]

guys i have one problem how can i solve is trigger to be checked without object moving on him

it only checks is trigger if object is moving

is there any work around for this

[dusky compass]

Hey, anyone know how I can fit my UI inside a rect with grid layout group?

I am trying to fit some UI items into a grid and I want them to scale based on the size of the parent container (with the grid layout component)

I can set the cell size to scale them but isn't there another way?

[covert whale]

if you have on trigger stay it should call as long as the collider is touching
https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnTriggerStay2D.html

[grave solar]

hey can somebody help me out with movement?

[compact knoll]

provide more details about what specifically you need help with and someone might actually help

[amber idol]

Hoi 👋🏻

Hope y'all doing good, I have a question

See my friend RussianGuard? See the little box right in front of his foot?

Basically, i want him to walk forward over a platform and if that little trigger collision box no longer overlaps with any ground tile, he should turn around.

How do you recommend I do that? What would be the most simple approach?

My idea is giving the box - which is connected to the guard - an Update() that checks whether or not it's overlapping with ground every frame

As soon as it doesn't, it sends RussianGuard a prompt; to which the guard reacts by turning around and walking the other day, rinse and repeat. Much like a Red Koopa Troopa would, for connoisseurs. 🤔

How do I check if the little collider trigger is overlapping with ground?

[amber idol]

I know I'm not the person above, but just in case you have any advice regarding my situation... any help is appreciated

[compact knoll]

You really shouldn't ping people randomly like that, kinda not cool and against #📖┃code-of-conduct
but you could use a boxcast or if you wanna do it in a really hacky way, you could use OnTriggerEnter2D/OnTriggerExit2D

[amber idol]

Does the reply button send a ping?

[compact knoll]

yes

[amber idol]

My bad

[gray perch]

Hi! I have the following situation and i'm wondering what will be the easiest approach.

I have 3 Locations and 3 Objects and i want each object to spawn on a random location (1 object per location)

Then i want to be able to detect if an object is at the correct location (Object 1 on Location 1, etc.)

Will appreciate any help or advice, or just pointing me what to google because i can't seem to find anything

[golden cedar]

Should be similar to key door systems, giving door/object some same identifier, and then checking if they are near each other

[gray perch]

sounds like a great place to start, thanks a lot!

[golden cedar]

no problem

[amber idol]

My tilemap somehow causes both me the player and an enemy to get "stuck" randomly
While moving left or right
I don't know why that happens
Any help?

[compact knoll]

don't crosspost, i just answered in #💻┃code-beginner

[normal river]

downloaded unity a few days ago and i'm just trying some stuff out.
I have a sprite above a square, and they both have box colliders perfectly alligned to the edges, but when i press play the sprite still floats slightly above the square.
i'm at a loss at what to do, i've tried google but none of the answers have helped.
yes, i've tried changing the default contact offset but that still doesn't help.

[compact knoll]

add a rigidbody2d to anything that you want physics (like gravity) for

[normal river]

i did that

to the player

it falls and then stops a slight but noticeable amount above the ground

[snow willow]

If its floating above then one or both of the colliders are misaligned

[compact knoll]

well that doesn't sound right. care to share a screenshot with gizmos enabled?

[normal river]

both colliders are practically pixel perfect

[snow willow]

Show them

[normal river]

and when played

floats about here

different scaling but still an issue, clearly visible in the game window

[snow willow]

I'd maybe put an OnCollisionEnter method on the player and print out the name of the collider it's colliding with

[normal river]

    void OnCollisionEnter(Collision collision) {
        Debug.Log(collision.collider.name);
    }

is this the correct code? cus if so i'm getting nothing

and i got this from https://docs.unity3d.com/ScriptReference/Collision-collider.html

[compact knoll]

it needs to be 2d so OnCollisionEnter2D with Collision2D as the parameter

[normal river]

mm thank you

[snow willow]

Sorry my bad - yeah you need the 2d version

[normal river]

alright they are colliding

player is colliding with square

[snow willow]

what is square - is that the ground?

[normal river]

yes

[snow willow]

can you select the ground and show screenshot of its collider gizmo(s)?

[normal river]

the green collider outline?

[snow willow]

yes

[snow willow]

and it only has one collider?

[normal river]

yes

box collider 2d

[snow willow]

Do you have any scripts on your player

[normal river]

nothing besides the oncollisionenter2d

[snow willow]

Oh also Project Settings -> Physics2D -> Collision detection Offset have you looked at that?

[normal river]

yes

so many times

doesn't really fix it

[snow willow]

You said default contact offset above

which is not the same

[normal river]

oh wait lemme

check that then

[snow willow]

unless I'm just reading something wrong here

[normal river]

where is that? i'm looking at physics2d and i don't see collision detection offset

[snow willow]

yeah I may have just misread something

[normal river]

if i adjust default contact offset to 0.0001 from 0.001 then the player dips slightly into the ground, which also isn't ideal

sorry not those values but generally there is no value that gets the player to not float

or maybe there is, but i haven't found it quite yet

should i just look for that

[snow willow]

dumb question but - is your camera aligned properly?

and are your objects on the same z coordinate?

[normal river]

yeah

for both

[storm coral]

Why am I getting health subtracted twice for each collision? https://paste.mod.gg/kceblqwspmia

[snow willow]

Does your player or your enemy have more than one collider?

[storm coral]

no

wait yes

dangit i thought i removed that

[feral parcel]

hi, i want to change the position of the golden one relative to the position of the hand, how am i supposed to do that

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

public class WeaponPickUp : MonoBehaviour
{
    public Transform hand;
    public GameObject weapon;
    public GameObject oldWeapon;

    void OnTriggerEnter2D(Collider2D other)
    {
        if (other.CompareTag("Player"))
        {
            Destroy(oldWeapon);
            weapon.transform.parent = hand;
        }
    }
}

this is my code

[vocal condor]

It's parented now so it would do what you say; change relative to the parent.

[subtle geyser]

Anyone know why the Default GameObject field would be missing from a RuleTile? All it gives me is the option for Default Collider.

[velvet magnet]

does anyone have pixelated 2d 0-9 numbers?

[covert whale]

google exists, there are plenty out there

[fleet remnant]

you need to select a sprite, not gameobject

u put the base sprite on the default sprite and then add rules for different sprites to apply

[subtle geyser]

https://docs.unity3d.com/Packages/com.unity.2d.tilemap.extras@1.6/manual/RuleTile.html is showing that there would normally be a Game Object field that I could select in addition to a sprite?

I've done it in previous projects as well, so I'm not sure what changed cuz it was in the same version of Unity as far as I'm aware

Cuz it'll spawn the sprite but also spawn a game object at runtime

I did some digging and it looks like the Game Object field was added in 2019.x and I'm using 2019.4.12f

I need a camera to follow the player but only on the y axis. How do I do that?

Hello there, I want to draw ray in 16 different directions. So starting from angle 0 i will add 22.5 degrees to the next line.

How can I do it?

https://www.youtube.com/watch?v=Xvd4aR6zd30

Want to do something like this

[snow willow]

Vector3 dir = Vector3.up;
int directionCount = 16;
for (int i = 0; i < directionCount; i++) {
  float angle = i * (360f / directionCount);
  Vector3 drawMe = Quaternion.Euler(0, 0, angle) * drawMe;
  Debug.DrawRay(transform.position, drawMe, Color.red);
}

[cerulean comet]

How does Physics2D.RaycastAll work on a 2D tilemap collider? I am doing a raycastall on a tilemap scene (see below) However the raycastall only ever returns 1 hit point. I am curious how Physics2D.RaycastAll interacts with the 2D tilemap collider. Thanks in advance.

[snow willow]

Tilemap collider combines all of the tile colliders into a single collider

[cerulean comet]

Thanks for the response, how does this inturn impact the RaycastAll? I was trying to find some information on this. Does the raycast check the same collider twice? Seeing as the tilemap collider is combined

If it does not check colliders twice, is there a work around that could be achieved?

If need be I can provide context to why I am trying to achieve this

[snow willow]

Not sure why it would check the collider twice. It will check any given collider only once

The workaround is don't use Tilemap Collider

Context would be good, yes

[covert whale]

do you have a composite collider on the tile map?

[grim lintel]

Hey so how do I make a character aim with a joystick using an animation of them rotating 360 degrees? I have this frame animation but I'd also like to know for bone-based

[glacial sky]

Hello once again. For some reason when I try to load the game view, Unity throws this at me NullReferenceException: Object reference not set to an instance of an object SpawnCard.CardCheck () (at Assets/Code/SpawnCard.cs:36) however there are no errors or warnings in code editor.
The error occurs because of this part. Note: setManaCounter is 'int' as is warrior.cost

idk why, because it's warrior's properties are public

this is the script of character's constructor

[covert whale]

right before this line, could you debug.log manaRefill and entity.warrior to see which is null

[glacial sky]

both are null

https://paste.myst.rs/y0b6yqrh
here are all the scripts in one place

[wide ginkgo]

Where do you assign manaRefil in SpawnCard?

[glacial sky]

you mean scripts or references?

[wide ginkgo]

public ManaRefil manaRefil;

[glacial sky]

SpawnCard.cs is assigned to UI buttons which indicate which prefab to instantiate
manaRefil.cs is assigned to a GameObject with slider component attached to it

[glacial sky]

these are used to check whether there is enough mana generated to spawn warrior

[wide ginkgo]

Can you double check that you assigned it? It shouldn't be null if you did. Also make sure that there's not multiple scripts in the scene where one might not have the reference. You can search the scene hierarchy with t:ManaRefil

[glacial sky]

do that search in Unity or editor (I use vscode)?

[wide ginkgo]

The hierarchy in Unity

[jolly narwhal]

The error is thrown by the SpawnCard component so you need to check the elements that have that component

so search for t:SpawnCard and check the references to manaRefil and entity

[jolly narwhal]

and now select each one in turn and check the inspector that all of them have valid references

[glacial sky]

they all have these checked (according to entity)

[jolly narwhal]

No, the SpawnCard component

[glacial sky]

I added mana bar and warrior prefab here, but now I get different error

[covert whale]

oh

where are you accessing any object's name

[hollow crown]

My guess would be that CardCheck is calling itself infinitely

[glacial sky]

I'm not, I assumed the info is passed between scripts, since access to needed values is public

[glacial sky]

CardCheck is called on button press

[covert whale]

    private void CardCheck()
    {
        
        if (selectCard.gameObject.name == "SelectCardWarrior" && manaRefil.setManaCounter >= entity.warrior.cost)
        {
            spawnWarrior = true;
            Debug.Log("selected card: " + selectCard.gameObject.name);
            spawnCost = 2f;

        }
        else if (selectCard.gameObject.name == "SelectCardArcher" /*&& mana.mana >= 3*/)
        {
            spawnArcher = true;
            Debug.Log("selected card: " + selectCard.gameObject.name);
        }
        else if (selectCard.gameObject.name == "SelectCardZeppelin" /*&& mana.mana >= 4*/)
        {
            spawnZeppelin = true;
            Debug.Log("selected card: " + selectCard.gameObject.name);
        }
        else if (selectCard.gameObject.name == "SelectCardDragon" /*&& mana.mana >= 5*/)
        {
            spawnDragon = true;
            Debug.Log("selected card: " + selectCard.gameObject.name);
        }
        else CardCheck();
        Update();

here

why are you calling Update?

and also CardCheck

[glacial sky]

to spawn entities on left mouse click in the scene

[hollow crown]

Is that not when this is happening? I have not been folllowing, all I see is that CardCheck is calling CardCheck

which seems like a potential infinite loop, which is all a stack overflow is indicating

[covert whale]

if you're new to coding recursion isn't recommended

[hollow crown]

Look at the full error and see if it hints at where it is

[covert whale]

you can end up in a loop which is happening here

[glacial sky]

ok, removing CardCheck call in else solved the problem

that was just dumb logic error

;d

[covert whale]

no need to call Update at the end of CardCheck too, that'll be called by unity every frame anyway

[glacial sky]

that's true, thanks for pointing this out :)

[covert whale]

also here, you can replace this whole switch statement with manaCounter.text = setManaCounter.ToString(), and ```
if(setManaCounter == 2)
{
allowSpawnWarrior = true;
}

doing setManaCounter-=2 doesn't do anything because you're not using setManaCounter outside of this method

[glacial sky]

I'm using it to convert mana (it's being constantly increased in Coroutine) to int (setManaCounter is int)

[covert whale]

you have setManaCounter as a parameter name, and also as a field name

what you're passing in as setManaCounter isn't the same as public int setManaCounter

[glacial sky]

I understood what you meant now, that mana deduction was in wrong script :D

hence it had no effect on mana value

it needs to be here :D

[covert whale]

the whole of entities.cs should be split up into something using polymorphism
you can have different classes, and use inheritance, an interface, or have scriptable objects instead, instead of having a bunch of bools and if statements to check what the entity is
https://www.w3schools.com/cs/cs_inheritance.php
https://www.w3schools.com/cs/cs_interface.php
https://docs.unity3d.com/Manual/class-ScriptableObject.html
this would be better than setting a bunch of bools and having if statements to set each property

[glacial sky]

yeah, I see that current entities.cs won't work as I want if I keep it that way, I'll change it the way you suggested

[covert whale]

and for things like castle.type, use enums instead of strings to avoid typos and to allow for it to autofill
https://www.w3schools.com/cs/cs_enums.php

doing some c# tutorials would help a lot in allowing you to organise this better

[spring compass]

how do i reenable collision between 2 layers after disabling it with IgnoreLayerCollision? im trying to make an action start by ignoring but then going back to normal at the end

[molten lance]

how do i make an object point at the mouse

[ancient path]

ok so

first you need a camera reference

then use the built in method to convert the mouse position to a world position

[molten lance]

Input.MousePosition?

[ancient path]

then get the difference between the objects position and the world mouse position

[ancient path]

yes

then get a float using the mathf.Atan2 method of the difference x and y times Mathf.Rad2Deg

then assing that float to the z rotation of the gameobject

[molten lance]

ok, thanks!

[ancient path]

np

i'll be here to explain

[molten lance]

ok why the heck won't an option show up in unity for cam

but my old Target is showing up??

ITS NOT EVEN IN MY CODE ANYMORE

HUH

im so confused rn

ive saved the script, ive tried removing the script component and adding it back

it just says no

deleting all the code and putting it back worked

ofc it did

why not

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

public class controller : MonoBehaviour {

    [SerializeField] private Camera cam;
    float xInput = 0f;
    float yInput = 0f;
    float stepSize = 1f;
    Vector2 mousePos = new();


    // Start is called before the first frame update
    void Start() {

    }

    // Update is called once per frame
    void Update() {
        xInput = Input.GetAxisRaw("Horizontal");
        yInput = Input.GetAxisRaw("Vertical");
        mousePos = Input.mousePosition;
    }

    private void FixedUpdate() {
        transform.Translate(new Vector2(xInput, yInput));
    }
}

why the heck is cam not showing up as an option here

unity recognizes that the script has changed

SO WHY WONT IT LET THE SERIALIZED FIELD SHOW UP IN THE INSPECTOR

[ancient path]

maybe is the class name

[molten lance]

how could the class name be the issue

[ancient path]

no idea might be worth a try

[molten lance]

i copied all the code over to a new script, changed the class name, still nothing

oh, there was an error hiding from me

lol

[primal notch]

I have two different coroutines running in 'parallel' that do RayCast2D with 2 different layer masks (Door and Arrow)
Door and Arrow Sprites in scene are overlapped (Arrow above Door) and I would like to make trigger only the Arrow RayCast2D and not the other one.
How to do that?

[molten lance]

ok, i made my player follow my mouse, but it always is looking 90 degrees to the right

code: transform.rotation = Quaternion.Euler(0, 0, Mathf.Atan2(transform.position.y - mousePos.y, transform.position.x - mousePos.x) * Mathf.Rad2Deg);

it seems kinda weird that it is 90 degrees off

180 or smth woulda made sense

[ancient path]

Use another variable you can modify in the inspector

And add that variable to the z rotation

[inland wind]

I have a question. I want to make it so my player dashes to the mouse pointer. I tried storing the mouse pos in a variable but then the power of the dash depends on how far away the mouse pointer is. im still a beginner so im not very good. sorry if the answer is obvious

[ancient path]

Normalize the direction

More specific

Normalize the distance to get a direction vector

A direction vector doesn’t affect speed

[inland wind]

sorry im rlly dum

i dont get it

ik normolize means that you turn it so the max value is 1

but i dont really know how to implement that

[ancient path]

Can you send a screenshot

[inland wind]

do i just do rb.velocity = mousePosition.normalized;

[ancient path]

It’s preferably better to use add force

[inland wind]

ok thanks

[ancient path]

And btw

Don’t use the mouse position directly

[inland wind]

mousePosition = Camera.main.ScreenToWorldPoint(mousePosition);
?

[ancient path]

It will give you the direction for an object placed at the origin (center)

Rather use
mousePos -= transform.position;

[inland wind]

do i subtract with the transform

yeah

thanks

forgot to do dat

its not working

[ancient path]

What exactly

[inland wind]

it;s still launching itself depending on the mouse pos

if i move it further

then it goes really fast

[ancient path]

Did you hit Ctrl + R

?

[inland wind]

?

[ancient path]

Did you refresh unity

[inland wind]

yee

heres my code

mousePosition = Input.mousePosition;
mousePosition = Camera.main.ScreenToWorldPoint(mousePosition);
mousePosition -= transform.position;
rb.AddForce( mousePosition.normalized);

[ancient path]

What happens if you change in the Camera.main the mousePos ti Input.mousePosition?

[inland wind]

like this?

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

[ancient path]

Yes

[inland wind]

it no work

[ancient path]

Ok let’s try

mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector3 difference = transform.position - mousePosition;
rb.AddForce(difference.normalized);

[inland wind]

nope

same thing

[ancient path]

Ok

Did you refresh unity?

[inland wind]

thanks tho

1 sec

still nothing

[ancient path]

Well

The problem is now not the code

Can you send a screenshot of your IDE?

[ancient path]

I said your IDE not unity

The code in visual studio

[inland wind]

ohhh

do i just copy and paste it?

srry im rlly dum

[ancient path]

No

Screenshot

[inland wind]

ok

[ancient path]

That isn’t visual studio

[inland wind]

how do i find it?

[ancient path]

Is the purple program

In the task bar

[inland wind]

the code doen't fit on the screen

i gotta go

srry

thanks tho

[kind island]

hi, this is in a coroutine, and i want the button to have an addlistener inside the coroutine by code. i can't do that. how do i do it?

pls help

[inland wind]

My brother made a math equation that changed the force my dividing it so it adds to a certrain number

it worked!

[smoky sable]

Would there be any drawbacks or bad practices if I were to use the different Layers to keep collision and rendering (clients only) separated whenever my players accessed new floors of buildings etc? Thought it'd be a decent way to keep the same translations and everything without teleporting players to different locations (it is a multiplayer game, so everything needs to be in the same world / scene)

[covert whale]

i don't think there's anything wrong with it, but too many layers can be hard to manage, so make sure it doesn't get out of hand if you have lots of floors

if you do have lots of floors, you may want another system such as messing with the z axis, disabling/enabling objects or components on different floors and so on

[covert whale]

are you trying to add an IEnumerator as a listener to an event?

[fluid cloak]

This looks like a nice game

[covert whale]

you'll have to add a method that has StartCoroutine(TheCoroutine)

[little loom]

Ok so for context I wanna have a spawner to create an enemy that will follow the player. Only issue is that when I made the character a prefab, they only followed to the location where the perfab is declared as, not the character itself. So uh, how to fix?

The 'Enemy' that I directly spawn initially works perfectly fine, but the ones spawned from the spawner however isn't

I can't drag the Circle directly to the transform slot, and if I make the Circle a prefab, the clones of the enemy will just go to where the prefab was made, not the player itself

[feral parcel]

hi, so apparently as you can see, i have the platform where my player is in, they both have colliders, and the platform is set on trigger

now

when it collides with the player

what it should do is

if (other.gameObject.CompareTag("Player"))
        {
            Debug.Log("I hit a player");
            for (int i = 0; i < spike.Length; i++)
            {
                spike[i].transform.position = new Vector3(spike[i].transform.position.x, spike[i].transform.position.y + yOffset, 0);
            }
        }

is there something wrong im doing

oh well nevermind

i found the prob

xD

[covert whale]

you'll need someway for the enemies to get a reference to the Player after they've spawned, and you can either do that by
dependency injection - when the enemies are spawned by the spawner, have the spawner pass them a reference to the player
singleton (this only works if you have only one player object) - make a public static Player instance in the player script, set instance = this; in awake, and have that be used to get a reference to the player

you can search up these two methods for a more detailed explanation/example

[little loom]

How can I use rb2D.AddForce() in the direction an object is facing?

[covert whale]

just multiply your force vector by transform.forward

[somber wyvern]

@covert whale ok, thx

[bright condor]

How can I make sorting layer order only affect sprites when they are in the exact same Z position?

so like if a sprite has sorting layer of 1 but its under another sprite the sprite above will always show?

[turbid heart]

put it on another sorting layer. not sorting order

[lucid frigate]

is there no 2d character controller? and if so should I still use a character controller and add 3d box colliders to sprites or just switch to 2d rigidbody?

[covert whale]

if you're using 2D, use 2d colliders and 2d rigidbodies

i don't think there's a 2d character controller but it's not difficult to do 2D movement, there are plenty of tutorials out there

[lucid frigate]

mhm ok

well I know how to do it but I just prefer charactercontrollers

[covert whale]

if you don't want any of the fun, go onto youtube, search 'brackey's 2d movement' and it's very simple

basically gives you a script

[still tendon]

I started creating a game whit rockets my player can move and that is ok and my rocket is following my player and it get destroyed when touch player but when i put rocket in script for spawning rockets its spawn but whet it get destroyed they stoped spawning and it missing a game object, and when i put it in prefab they spawn but are just spinning around. How do i fix that?

[covert whale]

don't crosspost

can you send your code and a video of this

[still tendon]

can but private

[covert whale]

sorry you need to send them here

i don't do dms

[still tendon]

ok

this is rocket mowement

[covert whale]

use one of the sites in #854851968446365696

[still tendon]

and this is spawn

[covert whale]

how are you setting target

[still tendon]

you mean this

[covert whale]

it looks like the Player object is outside of this prefab, so dragging that reference won't work

you'll need to assign what Player is to each rocket, and you can either do that with a singleton (static instance of Player) or dependency injection (pass in a reference when the rocket is instantiated)

[still tendon]

ok

i try and tell you if it works

[covert whale]

on the edge of my seat

[sudden fox]

I have this c# code which is supposed to make player arms follow the mouse

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

public class MouseFollow : MonoBehaviour
{
  int speed = 5000;
  public Rigidbody2D rb;
  public Camera cam;
  public KeyCode mousebutton;
  void update()
  {
    Vector3 playerpos = new Vector3(cam.ScreenToWorldPoint(Input.mousePosition).x, cam.ScreenToWorldPoint(Input.mousePosition).y, 0);
    Vector3 difference = playerpos - transform.position;
    float rotationZ = Mathf.Atan2(difference.x, -difference.y) * Mathf.Rad2Deg;
    if (Input.GetKey(mousebutton))
    {
      rb.MoveRotation(Mathf.LerpAngle(rb.rotation, rotationZ, speed * Time.fixedDeltaTime));
    }
  }
}
``` It gives me no error although it does not work either :/. I have a ragdoll joined with HingeJoint2Ds

[snow willow]

One problem - you have update instead of Update

another problem is that MoveRotation should only be done in FixedUpdate()

[sudden fox]

I am dumb

Thanks for the help <3

[lean estuary]

@sudden fox No reaction gifs, please.

[sudden fox]

:0 ok

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

public class MouseFollow : MonoBehaviour
{
  int speed = 300;
  public Rigidbody2D rb;
  public Camera cam;
  public KeyCode mousebutton;
  void Update()
  {
    Vector3 playerpos = new Vector3(cam.ScreenToWorldPoint(Input.mousePosition).x, cam.ScreenToWorldPoint(Input.mousePosition).y, 0);
    Vector3 difference = playerpos - transform.position;
    float rotationZ = Mathf.Atan2(difference.x, -difference.y) * Mathf.Rad2Deg;
    if (Input.GetKey(mousebutton))
    {
      rb.MoveRotation(Mathf.LerpAngle(rb.rotation, rotationZ, speed * Time.fixedDeltaTime));
    }
  }
}
``` Now when i try this script, it just points the hands in one direction and do not follow the mouse position. Any help would be much appreciated :)

[snow willow]

Are you using a perspective camera or orthographic?

[sudden fox]

YOU ARE A LIFE SAVER. Thank you so much. Pardon me for being so dumb

[spare coyote]

Guys i have problem have prefab that instantiate with game start but if resolution is 19:9 it is cutted on sides it does not fit into screen

maybe someone know where is the problem

[covert whale]

what are you instantiating?

[spare coyote]

Its puzzle game and im instatiating level that is premade prefab but i dont know how to instantiate it properly on every screen

Its same on every screen and if screen is slimer then it cuts it of

[covert whale]

do you have a set aspect ratio or is it in free aspect

you can see this in the game window

[spare coyote]

When im testing its on 16 9 when i put it on free aspect prefab is same size

Its always same size aspect does not matter

[covert whale]

you can get the screen's extents with Screen.width and Screen.height
use Camera.ScreenToWorldPoint of those values to get the extents of the screen in world position
then you can change the scale of the prefab depending on whether it falls outside of those positions

[spare coyote]

Ok so i should include screen width and screen height on code where im instantiating it i supose

I dont im gonna play with it im sure there is a way

Thanks for time

[versed halo]

Hey guys! I just got into programming and i have a first project in mind. I am really excited but really new, so ill be here a lot lol

I wanted to ask for help because my project has some game related characteristics, but is definetly not an actual game. My idea is a platform that people can get to organize themselfs and create a routine... it's inspired by a game called "virtual cottage". I don't know what tutorials to search for because if i search: unity 2d tutorial, there is only like, mario bros type of thigns

[ancient path]

organize as?

build levels?
or procedural levels

[compact knoll]

you'll definitely want to go through those basic tutorials and familiarize yourself with C# before you attempt to make something big. gotta learn to walk before you can run, ya know.

[civic cave]

👀

[versed halo]

i am not htinking anything complicated... is more because of the aesthetic of it. I am more a graphic artist then a programmer so the main area of it would be its looks

but i did a c4 model of it and i saw that my idea might actually be a little too complicated

[versed halo]

i just don't know how to look for tutorials... i watched a lot of C# tutorials, so now it would be time to learn a little more specific areas... but i don't know if game development would actually work for me

[compact knoll]

there is a "Beginning 2D Game Development" course on the unity learn site you could start with. And if you end up deciding that the actual programming side of things isn't for you, you can always check out the forums to find people to collab with so that you can focus on the art while someone else does programming.

[versed halo]

oooh, cool!. Because i made a list of the functions i would need, and the most complicated one, is building a spreadsheet. Because the idea was that the perosn could set a tiemr and title to a task, and put it in kind of a this spreadsheet, where the tasks u added are movable. The rest of the functios are basic, like... clokcs, timer, music and stuff

[civic cave]

@ancient path you good?

[ancient path]

yes

you?

[civic cave]

same haha been waiting for ya

[ancient path]

i thought you were doing it

lol

[civic cave]

idk how to do it lmao

I thought you were like, making a tutorial or something lol

[ancient path]

xd

well

wait a bit

Rigidbody2D rb;
public float speed;
    float horizontal, vertical;
    sword S;
    Vector2 direction;

    private void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }
    private void Update(){
        direction.x = Input.GetAxisRaw("Horizontal");
        direction.y = Input.GetAxisRaw("Vertical");
    }
    private void FixedUpdate(){
    rb.AddForce(direction * speed * rb.mass);
    }

@civic cave we said acceleration right?

and force movement?

[civic cave]

yup

[ancient path]

its pretty much done

you can then play with the speed and drag

[civic cave]

😳

what does sword stand for in the script? It's telling me the type or namespace name could not be found

[ancient path]

delete that

i copied an old sccirpt

[civic cave]

ok I'll test it now

maybe I did something wrong? It's not working as intended

[ancient path]

whats your rigidbody values?

[civic cave]

for the elevator?

[ancient path]

yes

[civic cave]

mass 1
friction 0
angular friction 0.05
gravity 1

Freeze position X checked, Y unchecked, Z checked

[ancient path]

uncheck all of them

put 0 gravity

[civic cave]

done

[ancient path]

try now

[civic cave]

it's floating away

lol

[ancient path]

ok

then check the x position

how strong is your speed?

[civic cave]

speed is 1

[ancient path]

increase it

[civic cave]

well it's not floating away anymore but it's like this

it moves with me tho

[ancient path]

constrain the rotation

[civic cave]

well now it's gone

[ancient path]

xd

[civic cave]

fell into the hole

[ancient path]

which hole?

[civic cave]

nevermind

it just goes away somewhere

[ancient path]

well

what

exactly goes

there

[civic cave]

I hit play and it already moves from the starting position and goes to the right

[ancient path]

go into an empty scene

[civic cave]

then it gets stuck in the wall and I can make it move/follow me with A and D

[ancient path]

and test the elavator there
