Nice, it works perfectly

Thanks

[orchid nest]

how do I test if two entitys are on the same grid space?

Could I collect the data through some kind of game manager and then feed it to the code as an if statement

btw Im working with an isometric grid

(you can ping if you want)

[lament spire]

There are many ways to implement this, but one way would be to have this big List with all of your gridspace entities and their positions, and when you want to check you would have to go through every entity and check their grid position

there are optimisations to this but this is simple to implement

[grand coral]

this may not be the best solution but i would track it with colliders, so when the colliders intersect you mark which one is on the same space and when it leaves mark it as not there anymore

I'm having a bit of trouble with coding a ladder in Unity. For some reason, the ladder is a bit slippery when the player climbs it (as in, once I let go of the vertical key, the player slides a bit before stopping). How do I fix this? This is my code:

[turbid heart]

Slides downwards?

[rapid wagon]

No, it slides in the direction it's climbing in

[grand coral]

give the ladder 100% friction with a physics material

[rapid wagon]

That didn't work, but I think it has something to do with my player's velocity (since instead of just setting itself to 0, it slows down to a zero)

[grand coral]

then set it to 0 when you want it to stop

rbd.velocity = 0

[steel stone]

im a noob at unity and was trying to make some kind of list system, where you click a button and add another item to the list. I don't want the list stacking though, and I want the "spawn Pos" empty gameObject to move like 100 or so down on the Y when I click a button. The button has an OnClick event that is titled spawnNewItem. Here's my code

 public GameObject item;
 public Transform spawnPos;
 public Transform parent;
 public void spawnNewItem()
 {
     var go = Instantiate<GameObject>(item.gameObject, parent);
     go.transform.position = spawnPos.position;
     
 }

[grand coral]

if you want spawnPos to move down, you'll need to reassign its position value as well after assigning go.transform.position

also you don't need the <GameObject> on the Instantiate, GameObject is the default

[steel stone]

oh

will it hurt it if i keep it

[grand coral]

probably not, it's just extra code

[steel stone]

oh ok

[grand coral]

doesn't really matter i guess

it would just look cleaner without it just my ocd acting up

[steel stone]

so i would just need to reassign go.transform.position

[grand coral]

no if you don't reassign spawnPos position as well then it will always Instantiate in the same spot no matter what

so in that same function at the very end put a line like spawnPos.position += Vector3.down * 100; or something like that

[steel stone]

ok thank you

[grand coral]

👍

let me know if it doesn't work

[steel stone]

i spent all night on this lmao im so dumb

1 sec let me test

dude thank you so much

it works great

[grand coral]

awesome

[orchid nest]

Its dynamic

it can change any moment

[desert cargo]

You can tweak the "gravity" of the vertical axis in the input settings

that will change how quickly the input axis returns to 0 after you release a button

(not to be confused with physics gravity)

[limber ruin]

Hey everyone! I've just been working on a project and i wanted to install 2D extras, but im getting this error - Library/PackageCache/com.unity.2d.tilemap.extras@9fbcb0960e/Editor/Tiles/RuleTile/RuleTileEditor.cs(310,26): error CS1061: 'ReorderableList' does not contain a definition for 'IsSelected' and no accessible extension method 'IsSelected' accepting a first argument of type 'ReorderableList' could be found (are you missing a using directive or an assembly reference?)

[signal tundra]

Hey guys, im trying to recreate hotline miami's movement and camera, but I'm stuck with this one problem - when moving in one direction, everything looks fine, but when you change directions it looks snappy, and I want it to look smoother. How would I be able to make it more like the game? Here's my game:

And here's hotline miami:

[turbid heart]

can you show us your movement code? use a paste site if it's long. see #💻┃code-beginner pinned

yeah, use a paste site please 🙂

[signal tundra]

ok hold on

Code for the character: http://pastie.org/p/2Xa0EIK6BXaokJmS0huvxY

[turbid heart]

your Input should be in Update

you need to separate the code that gets the Input, from the code that moves the player

[signal tundra]

alright, I'll try that

Code for the camera following http://pastie.org/p/6LYdoaNRRyx0N0u7r71t53

[turbid heart]

also, you might want to rename your Character method to something more like "MoveCharacter"

it should describe an action, not what it moves

[signal tundra]

done

How i can make the enemy bullet rotate in player direction?

[turbid heart]

look up "how to make object rotate to face another object unity"

[wide remnant]

That should be up there in top 10 google searches

[frank lintel]

can someone help me figure out why the tap event doesn't fire? http://pastie.org/p/6z2jVU3dFORukynKWv6Xbg

[wide remnant]

Anyways, Question:
I'm trying to detect if a trigger is in a collider, and also if the user presses the return key.
I've tried to use

private void OnTriggerStay2D(Collider2D other)
{
    Debug.Log("TRIGGERED");
}```
But it only returns true for ~23 frames

[wide remnant]

I think you're only testing for clicks and taps in Start(), not Update()

[frank lintel]

@wide remnant it works with mouse clicks tho

[wide remnant]

https://docs.unity3d.com/ScriptReference/Input.GetMouseButtonDown.html Can't you use this? Seems much simpler.

[frank lintel]

@wide remnant I'm using the system touch thingy

[wide remnant]

idk

Answered my own question: rigidbody should be set to 'never sleep'

[vivid trout]

Hi, I have some spanish tutorials 😄 for unity in 2d games.

https://www.youtube.com/channel/UCu-KRsLD1D50x7G5z4Kou5A/featured

[wooden ruin]

void OnCollisionEnter2D(Collision2D col)
    {
        if (col.gameObject.name == "TilemapFG" && hookState == 1){
            hookState = 2;
            hitPosition = transform.position;
            hitRotation = transform.rotation;    
        }
        if (col.gameObject.name == "PlayerPlane" && hookState == 3){
            hookState = 0;
        }
    }

probably the last thing ill have to ask for a while, but for some reason, the bottom one (collision with PlayerPlane) never works, and the top one (collision with TilemapFG) does. I've made sure that they are spelled correctly and they both have rigidbodies and edge colliders. and, no its not the variable that's causing it.

[snow willow]

Try adding a log statements at the beginning of the method to help figure out what's going on:

Debug.Log($"Collided with {col.gameObject.name}!", col.gameObject);

[wooden ruin]

it just doesnt register that it colides with PlayerPlane

other one works

[snow willow]

Have you tried any logging?

you're just guessing until you get in there and see what's actually happening

[wooden ruin]

not sure what you mean

[snow willow]

Try this: #🖼️┃2d-tools message

[wooden ruin]

yea i did

[snow willow]

maybe you will find some unexpected object is being collided with

and what happened?

[wooden ruin]

the only thing that happens is that it collides with the tilemap

[wide ginkgo]

Put Debug.Log everywhere in your Collision function, and see which ones happen and which ones don't

[wooden ruin]

is OnCollisionEnter2D a 1 time per run thing?

[snow willow]

?

[wide ginkgo]

You would also know thtis if you put Debug.Log

just put the damn log already

[snow willow]

He said he did 🤔

[wooden ruin]

????

[snow willow]

Can you show that this "playerPlane" object is?

Show its inspector

and what is the object that is supposed to be colliding with it

[wooden ruin]

ok

PlayerPlane

[wide ginkgo]

void OnCollisionEnter2D(Collision2D col)
{
    Debug.Log($"Collision with {col.gameObject.name}, hookstate is currently {hookState}");
    if (col.gameObject.name == "TilemapFG" && hookState == 1){
        Debug.Log($"Inside TilemapFG");
        hookState = 2;
        hitPosition = transform.position;
        hitRotation = transform.rotation;    
    }
    if (col.gameObject.name == "PlayerPlane" && hookState == 3){
        Debug.Log($"Inside PlayerPlane");
        hookState = 0;
    }
}

[wooden ruin]

litterally exactly what i have, minus the hookState thing which i can already see

[wide ginkgo]

Can you show the output log for this?

If you mean you see hookState in the Inspector,don't trust it as it's slow to update

[wide ginkgo]

Can you show the log from my code?

[wooden ruin]

it just never registers that it colides with the plane

[snow willow]

can you show the "hook"'s inspector?

Are you changing anything else about the hook when you change "hookState"?

[wide ginkgo]

Form the log you showed now it seems hookstate is never changed?

[snow willow]

Can two edge colliders colldie?

never used them

[wooden ruin]

it is changed, but you can only see the value when it colides with the tilemap, and when that happens its always 1

[wooden ruin]

that might be the problem, but i dont know why they couldnt

[snow willow]

can you show an image of what exactly we're working with here?

the scene

[snow willow]

also how are you moving the hook?

[wooden ruin]

hook is the black and brown thing

its complicated, ill just make a pastebin

[snow willow]

and what is playerPlane, in the picture

[wooden ruin]

the plane

[snow willow]

oh the blue airplane?

[wooden ruin]

yes

[snow willow]

I was imagining a mathematical plane

how come it's an edge collider?

seems strange

[wooden ruin]

hook controller
https://paste.ofcode.org/A8dgWLcRsmrNfu2GSzAeRW

[wooden ruin]

it just seemed like the best option, this is my first project

[snow willow]

ok so one problem here is you're moving the object (which has rigidbody) with transform.Translate

that will bypass physics

leaving you only with collisions when you're lucky enough that the colliders happen to overlap on a particular frame

[wooden ruin]

https://paste.ofcode.org/DjxMJy9rZGfbahh7ggLqua planecontroller

[snow willow]

Same there - also being move with transform.Translate

That makes collisions very... finicky

[wooden ruin]

yea but the hook is overlapping the plane and it still doesnt register the collision

its a grappling hook, it comes back

like here

and it gets constantly pulled onto the plane's position

[snow willow]

can you try using a polygoncollider instead of edge collider for a minuite

or even a circle collider

[wooden ruin]

changed the hook to a box

and it works

why is that a thing

[snow willow]

https://answers.unity.com/questions/832350/no-collision-with-edge-collider-2d.html

I think the way edge colliders work is they check if any part of their line(s) are inside the volume of the other collider. But Edge colliders don't have a volume

there's no concept of "inside" or "outside" an edge collider

so they can't collide with one another

[wooden ruin]

definetly switching all my stuff to polygon ones

that caused a really big issue i didn't think about

the hook is stored inside the plane but its just turned invisible, but now that they collide, the plane is constantly hitting the invisible hook and it breaks the flying

is there a way to disable colision with code

[snow willow]

you can disable the collider while it's in the plane

Collider2D has an enabled property

[wooden ruin]

would that be PolygonCollider2D.enabled?

because that doesn't work

[snow willow]

it would be .enabled on a reference to your actual collider

Collider2D myCollider = GetComponent<Collider2D>();
myCollider.enabled = false;
``` for example

[wooden ruin]

is there an operator like "within one of"

because then i could just do "player position (within one of) hook position"

[snow willow]

float distance = Vector3.Distance(playerPosition, hookPosition);
if (distance <= 1f) {
  // they are close.
}

[strange cove]

how to instantiate gameobject in clone object unity i still can't understand this....

[meager mural]

can you explain

[deep urchin]

Hello, I am trying to get an object to face towards the mouse, but slowly (It doesn't instantly face towards the mouse, it turn say 10 degrees each frame.) Here is my code so far:Vector2 mouseScreenPosition = Camera.position; Vector2 direction = (mouseScreenPosition - (Vector2)transform.position).normalized; transform.rotation = Quaternion.Lerp(transform.rotation, direction, 10 * Time.deltaTime);But I am getting an error saying Argument 2: cannot convert from 'UnityEngine.Vector2' to 'UnityEngine.Quaternion' and it underlines the word "direction" on line 2.
Is Quaternion.Lerp even the right thing to use? What am I doing wrong?

[turbid heart]

Lerp is correct, but you’re using it wrong. Look up how to use lerp correctly. There’s tons of guides

[deep urchin]

I think the problem is that direction is a Vector2. How would I change it to a quaternion?

[turbid heart]

Thats the other problem. Also look that up. It’s a basic google question

I just pointed out the less obvious one

[deep urchin]

Ok I'm doing this now, but now it always faces straight up. If it's "such a basic google question" then what is the answer because I can't find itVector2 mouseScreenPosition = Camera.position; Vector3 direction = (mouseScreenPosition - (Vector2)transform.position).normalized; Quaternion quaternion = Quaternion.Euler(0, 0, direction.z); transform.rotation = Quaternion.Lerp(transform.rotation, quaternion, rotationSpeed * Time.deltaTime);

[frank mason]

I have some questions about using tilemaps specifically about their physics. Is this the correct channel to ask in?

I don’t think it’s necessarily a coding problem

[late viper]

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

[deep urchin]

transform.LookAt only works for 3D (along the x and y axis). I want it to rotate along the Z axis for 2D.

[late viper]

but 2d doesn't have a z axis 🤔

you will have to use 3d transforms regardless, you can always zero out the components you don't need in the final rotation

[deep urchin]

? All 2D rotation is in the z axis, if you turn in the x or y axis it warps the object.

[deep urchin]

And the z rotation is always 0 because transform.LookAt is meant for 3D

[grand coral]

@deep urchin i think using quaternion's euler angles functions would be helpful to you, i always get confused trying to manipulate quaternions directly

or you could just use Vector2.Angle() to determine which direction to turn and then use transform.Rotate() to rotate a certain amount each frame rather than bothering with lerp

[burnt badge]

is there a way to get a list of ALL the objects currently on top of a trigger collider?

all objects with a collider themselves i mean

i know there is the OnTriggerStay2D method, but that only returns one collider at a time

[turbid heart]

on top? like within a trigger collider?

[burnt badge]

yes

[turbid heart]

never used this before myself, but try this
https://docs.unity3d.com/ScriptReference/Collider2D.OverlapCollider.html

[burnt badge]

oh my god how did i not know about this. if this is what i think it is, ive been overcomplicating a lot of things

[bright fjord]

You could also just have a list of colliders and add/remove in OnTriggerEnter and OnTriggerExit

[split edge]

^^^ thats the only sane way

you will need that list + a fix for removing disabled elements from the list if their gameobject gets deactivated because for Unity, deactivating a gameobject doesnt count as exiting the collision

I use a dictionary tho, just to have an easier time removing stuff

[deep urchin]

Ok, so I have an object that follows the mouse, but if I move the mouse or camera very quickly, then it lags behind and jitters back and forth. Here is the code:void Update() { transform.position = new Vector3 (Camera.main.ScreenToWorldPoint(Input.mousePosition).x, Camera.main.ScreenToWorldPoint(Input.mousePosition).y, 0); }

How would I fix this?

[turbid heart]

Try LateUpdate

[terse basin]

or use lerp

@deep urchin you are setting position directly so instead use a lerped value

@deep urchin https://github.com/jpgordon00/Unity2DCameraFollow

allows your 2D camera to follow with lerp one or many GO's

ya welcome people

[ebon galleon]

For some reason when running the game the IK Manager on the legs is playing, but in the animation window where I created it and tested it, it works fine. Anyone able to help? (There's also another issue where the player's jittering around if anyone knows how to fix that too). Thanks heaps https://gyazo.com/8542739632c14d9c67c107e5d71a5e72

For what purpose?

Thread within main thread or start a new thread from main thread?

[calm valve]

is there a way to instantiate an object at the location of every object that has a certain tag?

[abstract olive]

Sure, use FindGameObjectsWithTag to get an array of all the objects:
https://docs.unity3d.com/ScriptReference/GameObject.FindGameObjectsWithTag.html

Then loop through that array and use normal instantiation to spawn an object using the tagged object's position.

[calm valve]

damn, ty so much, I can't believe I couldn't find this lol

[indigo leaf]

Hey guys! I'm hoping someone might be able to help me out, I've been watching a bunch of videos but can't find one to explain this situation.
I'm working on a text based RPG, and I want to have a couple different character options to choose from. For example, you can choose your race, then your class, then your alignment. I'm wondering what the best way to go about this would be. I'm leaning towards setting up each individual character option as a scriptable object, but I'm curious how I'd assign that to the player. For example, if you picked 'Lawful, Human, Ranger' as your options, is there a way to assign the three objects to the player in a way that let's each one alter the player stats? Is there a better way to go about this?

[wide ginkgo]

What you said is how I would go about it. You can add functions to a scriptable object, it's not necessarily a pure data object.

Look up the pattern on how to use ScriptableObjects as an Enum substitue

[indigo leaf]

I'll look into it! Thanks for the advice.

[quiet bluff]

I've got a bit of a problem here, and I'd like to hear how you guys would approach it. Basically, I've followed a few tutorials and messed around a bit and got a mesh shooting out in a cone from the player character. Objects in a certain layer cast obstruct the mesh, basically creating a realistic Field of View effect. All good there, except, well, I need to find a way to make it so that Enemy units only appear when under the mesh, and I'd also like every part of the map not under the mesh to be slightly obscured. I've scoured the web for an answer, but most of them rely on custom shaders -which I haven't managed to get working and, even if I did, I'd then have to sacrifice 2D lighting provided by the Lightweight Render Pipeline package. Do any of you have any idea on how to solve this?

[lean estuary]

You should make a visual mock-up of what you are asking exactly.

[forest portal]

guys, I saw zyger using something that's called PlayerPrefsX, and it adds more to playerprefs, but idk how to use it

[snow willow]

https://wiki.unity3d.com/index.php/PlayerPrefsx

it's super old though

and written in javascript

so I'd recommend not

[forest portal]

oh damn, so no bool saving?

sad programmer noises

[snow willow]

just save as an int

0 for false, 1 for true

[forest portal]

I tried that method but

I just don't like it

[snow willow]

¯_(ツ)_/¯

[forest portal]

I mean I'm a chad 13 yo programmer lol

I can do it

but idk

[snow willow]

public static void PPSetBool(string key, bool value) {
  PlayePrefs.SetInt(key, value ? 1 : 0);
}```

[forest portal]

PPSetBool, hmmm sus

[snow willow]

public static bool PPGetBool(string key, bool defaultVal = false) {
  int result = PlayerPrefs.GetInt(key, defaultVal ? 1 : 0);
  return result == 1;
}```

[forest portal]

oh wait it's playerprefs

nvm

srry

[forest portal]

hmmm I'll try that

[quiet bluff]

Well, the effect has been achieved. I will post a picture of it in action in a moment.

As you can see, the field of view is obstructed by the block on the upper side (which is actually just the floor sprite rescaled into a block) while the block on the right side does not obstruct it. I couldn't properly show it here, but if you move the FOV away from the rightmost block it wouldn't show in the "darkened" portion of the map.

However now I have another problem, said problem being that to achieve this effect I had to use a URP "normal" renderer instead of a 2D one, set like this:

(I can provide the full info on how they're set if anyone needs them)

This prevents me from using the 2D renderer lights to illuminate my sprites, which is something I REALLY want to do. I am trying to use camera stacking to use both renderers at the same time, but the lights in the "overlay" camera don't render properly.

[indigo leaf]

Forgive me for the noob question.. but how did you embed your code like this?

[craggy gorge]

What's the most efficient way to rotate hundreds of gameobjects in 2d? Using quaternion.RotateTowards() is killing my performance

[marsh quail]

try setting the pixel per inch as same as your sprite pixels

[fickle plover]

hi

[dusky wagon]

Pixels per unity have to be the same as the size of the sprite

[faint sparrow]

you want rotate hundred of game object at same time??? ofc that killing performance

[craggy gorge]

Yes basically I am trying to check the maximum possible NPC agents that can he active on screen. I can have a 100 spaceships on screen without any problems. But when I activate their weapons (turrets that are children to the ships), framerate tanks. So I was thinking if there was a simpler way to rotate 2d stuff

[faint sparrow]

hmm tbh i never know 100 of game object can fit on 2D space, even that pretty small(and its useless since its will looks bad), i dont know what should be better, lets wait for someone else

[ruby karma]

@craggy gorge you can try writing the Quat.RotateTowards thing in C# to reduce calls to the cpp side. Might gain a few frames, as well as, you can look into the jobs system, specifically ParallelForTransform jobs

[craggy gorge]

That's what I was thinking but unfortunately my math is failing me here. Is there a formula to rotate a vector?

I found a matrix multiplication formula but I have yet to understand and try it

[snow willow]

I really doubt the problem is the performance of the function itself

it's the fact that you have hundreds of Update calls each frame

but you can check yourself with the profiler

[ruby karma]

^^^ should check in the profiler before doing that

[craggy gorge]

I have added the profiler and the code. Maybe I am doing mistakes that a more experienced dev can identify

I am calling the turret rotate function from a centralised manager's update ()

[snow willow]

Are there 102 calls to TurretSystem.Update()?

[craggy gorge]

Yes 102 calls, taking a total of ~6ms

Well 102 calls from a 102 ships. It's not fully centralised yet

[snow willow]

right I thought you were using a centralized manager

so there was only one update

but you're calling that "one update" 102 times?

[craggy gorge]

Nah. It's centralised only to the ship right now. I want to first flesh out how turrets work before I can centralise it completely. Just wip code that I started today and trying to see how I can optimise it

[mighty wren]

Any body here to rat-cast rendering in unity similar to doom? Was thinking about rendering each line to a sprite in UI d updating it in Update, is there anything wrong with this

[flint girder]

Are the colliders marked as triggers? If not, maybe "OnCollisionEnter2D" is the function you need instead?

I have a special screen in my game where I'm trying to grey out the scenery but leave targetable objects still coloured

At the moment I'm doing it to the whole level at once.

And only to the tiles.

But it's not very performant. Is there a way I can access just the tiles and objects (that aren't targetable) on screen?

perhaps if I can get all objects and tiles on screen I can just filter out the targetable ones

?

Hi, got a question about pausing/delaying a 2D game. So I have an UI with buttons and changing text. I want when I click the button to change temporarily to green, then wait, the change back to the original color

[hot fog]

Hey im making a 2d rpg kinda inspired by undertale so at the moment i have my camera as a child of my sprite but that just makes it follow the sprite around wherever how would i make it so that the camera stays still until the sprite reaches near the end of the screen then it starts following them till the edge of the level

[lament spire]

you could have a script on your camera that in the Update() loop sets it's x and y positions to the player's x and y.
Then you can check if your camera is too low or too high before setting the position so it only moves if you are in the middle

[hot fog]

Yeah im new to c# so i dont really know how to do that

Jittering is the camera not being updated in-step with the player or updated too close reflecting physics. You want to use smoothing on the camera that averages player position, not follows every frame is this case, probably.

[ebon galleon]

I'll give it a crack, thanks!

[worldly reef]

You could move the object, find it location in world points, and then set that to the parent's transform. I have to ask, if you want object A to follow object B, why is object B the parent? The main function of parents is to set up this sort of connection. Maybe that doesn't in your case.

im just having a bunch of build problems im sorry 😭

• I have text on a canvas - it isnt showing up in the build - it is in the game view in the unity editor.
• Not sure if editing the canvas text is working but meh
• i have a for loop, that just inst being executed??? It gets executed once but then thats it. It works perfectly fine in unity though, just not the built version

The code to add more "points" to the view - the loop only gets executed once

i also had a load of issues with building and all my camera settings reverting to defaults, so i have had to initialise the camera with code too 😭

The text on a canvas, gets edited;;;

public Text canvas; // HERE
    public GameObject point;
    public float speed;
    private int totalOnScreen;

    private void Start() {
        totalOnScreen = 0;
        gameObject.transform.position = new Vector3(-46.2f, 39.6f, 43.1f);
        gameObject.transform.rotation = Quaternion.Euler(41.185f, 111.561f, 104.436f);
        gameObject.transform.localScale = new Vector3(0.56023f, 0.56023f, 0.56023f);
        GetComponent<Camera>().backgroundColor = new Color(0, 0, 0);
        GetComponent<Camera>().orthographicSize = 34.7f;
        canvas.GetComponent<Text>().text = "Amount on screen: " + 0; // HERE
    }```

vs

[sturdy dome]

that looks tripy

[real lynx]

no text 😭

That second image was taken from a direct uhhh

direct build of the top one

also everything is so fast in the top one, and slow in the bottom, why cant unity be consistent ;~;

but whatever, ive edited the speed for the second

but WHY NO TEXT I DONT UNDERSTAND-

[sturdy dome]

i wish i could tell XD

[real lynx]

im sorry 💔

also the for loop is now working oddly

my understanding diminishes by the day

[orchid nest]

So Im having some trouble with cloning prefabs

So I have a button where if you press it a prefab will spawn and you can move it around and the prefab is suppose to follow the mouse

and all works well untill you click to spawn the prefab and it goes to some random location and it de activates

[dense flame]

Try putting all the information on a single message

That way no one interrupts you while talking

[orchid nest]

ah okay

my bad

[dense flame]

So when you Instantiate without setting position it uses the position of prefab

[orchid nest]

ah okay

[dense flame]

Try setting some position when instantiating

Instantiate(myPefab, somePosition, Quaternion.identity)

[solid turret]

Hey guys, do we have a channel for DevOps/Deployment?
I am having problems with WebGL deploy 😦

[orchid nest]

still doesnt work

GameObject a = Instantiate(spawnee, new Vector3(0, 0, 0), Quaternion.identity) as GameObject;
            mangrove.alreadyClicked = true;

[dense flame]

Dunno what that is but ask in #archived-code-general

[orchid nest]

mangrove.alreadyClicked = true;

This is referencing another script

the placement script to be exact

[dense flame]

Which scripts do changes to the prefabs?

[orchid nest]

These two

1. Mangrove Placement Script

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

public class MangrovePlacement : MonoBehaviour

    GameObject otherEntitys;
    Vector3 dragOffset;
    public float gridSize = 5f;
    private Vector3 oldPos;
    private Vector3 roundedPos;
    public bool alreadyClicked = false;
    // Start is called before the first frame update
    void Start()
    {
        gameObject.tag = "GroundEntity";
        oldPos = transform.position;
        otherEntitys = GameObject.FindWithTag("GroundEntity");
        return;
    }


    // Update is called once per frame
    void Update()
    {
        if (alreadyClicked == true) {
            transform.position = GetMousePos() + dragOffset;
        }
    }

    public void OnMouseDown() {
        if (alreadyClicked == false)
        {
            dragOffset = transform.position - GetMousePos();
            alreadyClicked = true;
        }
        else if (alreadyClicked == true) {
            gameObject.tag = "Untagged";
            var currentPos = GetMousePos();
            roundedPos = new Vector3(Mathf.Round(currentPos.x / gridSize) * gridSize, Mathf.Round(currentPos.y / (gridSize / 2)) * (gridSize / 2));
            alreadyClicked = false;
            if (roundedPos != otherEntitys.transform.position)
            {
                transform.position = roundedPos;
                oldPos = transform.position;
                Debug.Log("2");
            }
            else
            {
                transform.position = oldPos;
                Debug.Log("1");
            }
        }
    }
    Vector3 GetMousePos()
    {
        var mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        mousePos.z = 0;
        return mousePos;
    }
}

hi

[orchid nest]

2. The button

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

public class Mangrove : MonoBehaviour

    public Text text2;
    public MoneyCalculator money;
    public VillagerButton villagerButton;

    // Update is called once per frame
    void Update()
    {
        text1.text = price + "$";
        text2.text = villagerAmount.ToString();
    }

    public void OnClick() {
        if (money.moneyAmount >= price && villagerButton.villagerAmountThatPlayerHas >= villagerAmount) {
            money.moneyAmount -= price;
            
            price *= 2;
            villagerAmount *= 2;

            GameObject a = Instantiate(spawnee, new Vector3(0, 0, 0), Quaternion.identity) as GameObject;
            mangrove.alreadyClicked = true;
        }
    }
}

Hope this helps

[solid turret]

sorry no spanish
just English & Estonian

[dense flame]

For, while, do while, foreach

And use English

[faint creek]

how do you make something go forward using vector2 because Vector2.forward doesnt work and i can use Vector2.right for example because my player can flip

[dense flame]

I don’t get what you mean

Vector2 is 2d and it’s only up, down, left, right

[wide ginkgo]

Depends on what forward means in this case. You could use transform.right if you want relative "right"

[faint creek]

by forward i just mean straight ahead

[wide ginkgo]

There is no straight ahead in 2D?

[faint creek]

i know that why im asking for help

[wide ginkgo]

No i mean there literally isn't a 3rd axis in 2d

[faint creek]

i know

ok well i mean straight left or right

[wide ginkgo]

So you can't move something "forward". You could use Sorting Layers to sort objects if that's what you're after.

[faint creek]

i have a gun

that shoots

but

[dense flame]

You mean where it’s facing?

[faint creek]

yes

id like it to shoot the way the player is facing

[dense flame]

How does that change?

Is it a top-down?

[faint creek]

yes

[dense flame]

Then transform.forward, transform.up or something like that

[faint creek]

but im using Vector2

and i have to use it i cant use transform

[dense flame]

Why?

[faint creek]

because its a bullet

using vector it shoots off but transform only keep it in place

[dense flame]

transform.up returns a Vector3

Convert it to Vector2 and set it to Rigidbody speed

(In the case you use Rigidbody2D to change bullet position)

[faint creek]

ok thanks

[orchid nest]

Hey can I get some help with my problem?

[dense flame]

Can you stop asking help everywhere?

Oh I see, #💻┃code-beginner is occupied

[orchid nest]

yeah

my bad

[dense flame]

It might be a problem of the script that moves it to mouse position

[orchid nest]

Im sorry I dont get it

wdym?

[wide ginkgo]

wrong channel?

[orchid nest]

My game is in 2d

I think its fine

[wide ginkgo]

? I replied to nyancode

[orchid nest]

Im pretty sure that he was helping me out

and you seemed confused

[dense flame]

Yeah it was to help you

How do you handle following mouse position?

[wide ginkgo]

Ah right, my mistake

[orchid nest]

dont worry its fine

[orchid nest]

if (alreadyClicked == true) {
            transform.position = GetMousePos() + dragOffset;
        }

[still tendon]

for some reason, when jumping, this code seems to work fine in the editor but not in the built executable:

        if (Input.GetKey(KeyCode.W) && !isJumping) {
            rb.AddForce(new Vector2(0, 0.2f), ForceMode2D.Impulse);
            jumpFrameCounter += 1;
            if (jumpFrameCounter >= 80 || Input.GetKey(KeyCode.W)) {
                isJumping = true;
                jumpFrameCounter = 0;
            }
        }

isJumping is set to false when touching the ground, that much works
you can see isJumping in the top left along with the status of the jump key

[orchid nest]

@dense flame is it ok if I dm you

[still tendon]

w for this specific case

[orchid nest]

there seems to be too many people talking

and I feel like my issue is quite complex

[wide ginkgo]

Is your code in Update or FixedUpdate?

[still tendon]

update

fixedupdate seems to make it not work in the editor

[wide ginkgo]

So basically Update happens every frame. When you play in Editor you most likely have hundreds of FPS, which means it happens a lot. When you make a build and play it's usually capped to 60FPS. So it's not happening as often.

So when you are working with physics you want all the AddForce etc to happen in FixedUpdate, because then it will always happen at (default) 50 FPS

So your issue is that you jump currently is framerate dependant. Moving stuff to FixedUpdate will fix that. Although Input might be a bit wonky then, so try splitting the input to happen in Update and then read the input values in FixedUpdate

[still tendon]

okay, i'll look into that

thank you

[frigid shoal]

any tutorial for a top down, open world RPG?

[viral moss]

https://www.youtube.com/watch?v=P98iXcpN9YQ

This series might get you what you're looking for.
It's attempting to replicate zelda rather than a typical RPG but there's plenty of tutorials on making RPG combat systems. So this tutorial series can probably help you get the top-down open world part sorted.

I really liked the room system it used at some point and used it for a platformer 👌

[frigid shoal]

i would also like to integrate some more elements, like a money system and bosses

so how would i put that code into the existing tutorial code?

[snow willow]

Integrating large complex game systems together is a huge amount of work. That's basically the bulk of what you will do programming-wise for your game.

it's not something you can simply drag and drop

[orchid nest]

Hi so can anyone help me out with my problem
I know its quite annoying of me to ask multiple times but this is an assignment I need to hand in soon. Also if you are willing to help it would be better to do it in dms as conversations can get cut off in the channel

[abstract olive]

@orchid nest This isn't the Discord to ask for free personal help.

[orchid nest]

uhm

[abstract olive]

Just post your question and if someone's available, they can help you.

[orchid nest]

Sure

makes sense

[terse basin]

aint no body doing a free assignment for you

no body smart atleast

[orchid nest]

Alright so Im trying to make it so that when you press a button it will spawn a placeable object that you can move around but there are a few problems.

1. When pressing the button it will spawn a tree that you can move around with just moving your mouse but if it interacts with other trees it will un select and not be usable
2. If you press left click, the normal key to spawn a tree, you will stop moving it and it will go on a random number on the x axis and disapear

So that is the problem, and the weird thing is, I never told the clone to do any of this, its like it has a mind of its own

[abstract olive]

Nothing has a mind of it's own, it's doing what you're telling it to, regardless if you think otherwise.

So, when you press the button, is it spawning the tree correctly? How are you trying to make it move with your mouse?

[orchid nest]

I make it move with the mouse with once you press the sprite it will go to the position of the mouse

in a void update sequence

I can post my code if you would like

[abstract olive]

Use a bin site to share it.

[orchid nest]

http://pastie.org/p/6Bb6cprN08Oas3LV9f17aL

[viral moss]

If your trees aren't intended to collide with each other, you could put them on a layer that can't collide with itself.

[orchid nest]

if they collide

I wrote a line of code that just tells them to go back to there original place

but thats if you press the left mouse button again

but now if you just make them interact the sprite will just disapear

[abstract olive]

This code is a bit messy. Why not start by just getting the trees to follow the mouse without any fancy offsets or collision detection.

Just straight transform.position = GetMousePos();

Because if that doesn't work, nothing you layer on top of it, will.

[orchid nest]

ok got it

what else

[abstract olive]

Got it as in ... you understand, or it's working?

[orchid nest]

I understand

still doesnt work tho

[snow willow]

string someString = "apple";
LivesText.text = $"LIVES: {someString}";

This also works:

string someString = "apple";
LivesText.text = "LIVES: " + someString;

[storm coral]

Is there anyone who can help me step by step to make a block-based lighting system?

i really need the help because just by myself i wouldnt be able to do it, and i have no idea where to even start

[orchid nest]

@abstract olive so have you figured something about it? Still having trouble with it

[snow willow]

new Vector3(0, 0, 0)

you have to use constructors in C#

of course for 0 you can just use the predefined Vector3.zero

it's like a function that creates/initializes an object and uses the new keyword

Vector3 spawnPos = new Vector3(1, 2, 3);

https://docs.unity3d.com/ScriptReference/Vector3-ctor.html

[late viper]

then get that to work. nobody is going to magically find out what the problem is just by reading that script for you, you need to narrow down what may be causing the bug yourself

[orchid nest]

I tried to explain it as much as I can

I dont really know what to say else

[snow willow]

you can't instantiate a Vector3

The first parameter must be a UnityEngine.Object type such as a GameObject or Component

[late viper]

its not your explanation thats the issue. you need to do the debugging. get osteel's suggestion working, just a basic placement without collision

@orchid nest

[snow willow]

See the docs for the parameters order

https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

also your IDE should show you which is which

[orchid nest]

tried that but maybe I could go with one problem at a time

so first Im trying to figure on how to tell a clone to go somewhere

go to your camera and press f

multiple times

[late viper]

don't spam

you add the parent's transform as part of the parameters to Instantiate

for example Instantiate(myObject, myParent.transform)

yes

yes

the inspector is showing you the local coordinates

are you expecting the position you give it to be world or local coordinates?

https://answers.unity.com/questions/31169/explanation-local-vs-global-space.html quick explanation

if the position you give it is world coordinates then it should be at the correct position. Is it correctly placed in the scene?

again, the inspector will show you the local coords. can you see it in the scene?

[snow willow]

there's no way you want it at z = -5520

unless your camera is in some equally ridiculous place

[late viper]

I wasn't going to question that until later 😛

[snow willow]

anyway this is local position

not world position

I'm guessing either your camera is in a silly place or you have some silly scaling on a parent object

wait this object is a child of a canvas?

Is it a UI element?

[late viper]

that explains the scaling

[snow willow]

why is it a child of a canvas if it's a world space gameobject

[late viper]

thats kind of a problem if you are using it 😐

[snow willow]

It gets the BoxCollider2D component from the GameObject your script is attached to and enables it.

you're enabling it on the object this script is on

not the instantiated object

var newPlayerInstance = Instantiate(player, spawnPos, Quaternion.identity);
newPlayerInstance.GetComponent<BoxCollider2D>().enabled = true;

not the instance of the script that is running currently

anyway if that's the case you should probably just put this code in Awake() instead:
GetComponent<BoxCollider2D>().enabled = true;

Because it could be anything

You could have something like:

MyPlayerScript player;

in which case it would be:
MyPlayerScript newPlayerInstance = Instantiate(player, spawnPos, Quaternion.identity);

but I didn't want to assume anything

in fact I would recommend using prefabs that way to avoid calling GetComponent right after unecessarily

it just copies the state of... whatever it's copying from

well you are Destroying the player

right before you copy it 🤔

which... technically should work since Destroy is delayed till end of frame... But idk - you sure you're not disabling that stuff when the player dies for example

seems pretty likely you're disabling the stuff as the player dies

which you're then copying.

It's pretty unusual to do things this way. Normally the player would be a prefab, rather than Instantiating the player based on another object in the scene already

you wouldn't put it in the scene if it's a prefab

you would instantiate it at runtime

then you can reuse the prefab across different scenes

and respawn it without worrying about its current state in the scene

what about in your other code

&& see wht happens if you do the Destroy last

[hot fog]

Im struggling to make a script for my camera that only follows my player when its about to leave its view but doesn’t follow it when its near a wall basically i want to make a camera that follows the player how the camera follows the player in undertale

[viral moss]

@hot fog I think what you'd need to do is that the current room the player is in has a minimum and maximum value for where the camera can go. So that when it approaches the edge, it'll hit the 'limit' and can't move further in that direction.

[hot fog]

I dont know how to do that

[viral moss]

https://youtu.be/OWJa6lcFTXk
I think this vid does a decent version of it

[hot fog]

hey all, how do I go about making a floor for a 2d game

I tried importing apicture, setting wrap to repeat, but when I drag and drop the image it won't repeat if I stretch the object

[opal socket]

Tilemaps

[ripe wind]

tru

looking into those now

I noticed the example given is for 2d pixel-art games

that shou;dn't be an issue tho ignore me

Open the layer matrix and remove all the other layers but the one you want.

i am using the URP for my game, and would like to have complete darkness. For some reason, there is a sort of global light coming from somewhere and brightening everything up. How do I find this light to fix it?

[chrome lintel]

This engine is making my brain kinda hurt aha
So i have code set up for a 2D map that was supposed to be seemless with no load zones. Basically it loads new tile maps as you step from one map to the next. Basically you have a serialized Cells array that holds the tilemap prefabs it should load at what position in a second array. In the unity inspector I have the zone12 prefab loaded, but when the code is actually running it's reloading itself? I dunno what I could've done wrong since things are so simple right now (Posting screenshots in a sec)

So this is the zone11 object in the inspector

Code that loads it

[snow willow]

wdym by "reloading itself"?

what scripts are on the Zone12 prefab?

[chrome lintel]

Sec

whoops

No scripts in zone12

cause i didnt even get to that yet

and nothing in my code touches cells aside from the code i sent

[snow willow]

so what am I supposed to be looking at here?

[chrome lintel]

I dont even know dude this is annoying as hell

Cells is supposed to hold Zone12

[snow willow]

can you show the rest of the code?

[chrome lintel]

as shown by the first SS

Yeah no problem

public class WorldCell : MonoBehaviour
{
    [SerializeField]
    private GameObject[] cells;

    [SerializeField]
    private Vector3[] relativeLocation;

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.CompareTag("Player"))
        {
            GetComponent<BoxCollider2D>().enabled = false;
            LoadConnectedMaps();
        }
    }

    private void LoadConnectedMaps()
    {
        Grid grid = GetComponentInParent<Grid>();
        for(int i = 0; i < cells.Length; i++)
            Instantiate(cells[i], grid.transform).transform.position = relativeLocation[i] + transform.position;
    }
}

[snow willow]

Is it possible this script is on more than 1 object in the scene?

[chrome lintel]

Uhhhh

it SHOULDNT but weirder things have happened

[snow willow]

e.g. in your debugging - what's the name of this GameObject

[chrome lintel]

I see

the script somehow ended up in both the empty game object that held the tilemap and the tilemap itselkf

and that array has Zone11

Tyvm

[snow willow]

there ya go

[chrome lintel]

I did what is called a goof

[snow willow]

it happens ¯_(ツ)_/¯

[chrome lintel]

I know how

I edited the object while the game was running

lmao nice

and it got reset

without me realizing

Works like a charm

hot asf

[ripe wind]

So I tried making a palette for a tilemap and I got this when I dragged in the images (which I split into multiple different smaller sprites first)

it's not flush with each tile

yet in the inspector they don't actually seem to be cut off like they are here

[fringe pumice]

sooo for some reason my room has its center on 0,0 and this is waht i want but my other rooms has there bottom right corner at the 0,0 anyone know how to fix?

[storm coral]

why is my line renderer always turning out pink?

public void Start() {
        LineRenderer lineRenderer = gameObject.AddComponent<LineRenderer>();
        lineRenderer.startColor = lineColor;
        lineRenderer.endColor = lineColor;
}
public void Update()  {
        LineRenderer lineRenderer = GetComponent<LineRenderer>();
        var t = Time.time;
        lineRenderer.startColor = lineColor;
        lineRenderer.endColor = lineColor;
        lineRenderer.startWidth = lineWidth;
        lineRenderer.endWidth = lineWidth;
        lineRenderer.SetPosition(0, new Vector3(transform.position.x, transform.position.y, -1));
        lineRenderer.SetPosition(1, new Vector3(mouse.position.x, mouse.position.y, -1));
}```

i set my lineColor to green

nevermind, it was a rendering error

incompatible material

[still tendon]

i need help the character isn't showing up

[hollow crown]

Make sure it's inside the camera's clipping planes (the Z position of the transform should likely be 0)

[still tendon]

@hollow crown do i set the scale for the z axis to 0?

[hollow crown]

The position

Scale should be 1

[still tendon]

yea thats correct'

[hollow crown]

click off the 2D mode and check where it is in depth

[still tendon]

ok did that

do i move the background up?

@hollow crown

[hollow crown]

Where is it in space? is the character not visible at all?

[still tendon]

no

[hollow crown]

if it's not visible in the scene view at all, where's its sprite?

what happens if you move it so there's no objects around it, can you see it at all?

[still tendon]

im just new to unity i dont really know where 😭

no

i can try and reload the assets into the game

@hollow crown

[hollow crown]

2D objects will only exist with a sprite renderer component on it, and I haven't seen that, I can't tell what you're trying to render, so 🤷

[still tendon]

ok sorry for bothering you XD

@hollow crown

[hollow crown]

It's not a bother, I think you might want to start with some tutorials if you haven't already though, there's some good 2D starting points on Unity Learn.

[still tendon]

ok thank you

So I made a button where you can purchase something then place it down and once you place it down it goes to some random location on the x axis and then sets itself to not active

http://pastie.org/p/6Bb6cprN08Oas3LV9f17aL

But now I just found out that its for all my prefabs

and I have really no idea why

[orchid nest]

ok so I got it back to working so that its just the clone that does it

but its not really a fix

its more like I had to restate everything

[orchid nest]

Ok so I fixed

it

[potent iris]

You gave them the right tile size?

I'm trying to use 2D Sprite Atlases, but there seems to be no rhyme or reason as to what order it packs the sprites.

[dusty jolt]

how do i rotate an object without breaking any joints attached to it?

basically i want to avoid this
https://i.imgur.com/DFDvLKl.mp4

[mortal ginkgo]

can anyone explain why this is happening and if you do then how can i fix it, its suppose to be a softbody figure

[ancient wing]

lol

[sturdy dome]

is it supposed to stay in that shape?

[worldly reef]

What's a good way to check if an collider is stuck inside of another? I'm currently getting the bounds of the wall and seeing if contains bounds.min or bounds.max of the other object. It seems to be working, but I was wondering if there was a better way to do it.

I take it back, it's not working 100% of the time

[grand coral]

you could have a variable that stores a collider name and set it in the OnColliderEnter function

then set it to null or “” in OnColliderExit

[mortal ginkgo]

yes

[snow willow]

keep references to them in a List or other collection. Then loop through the collection and destroy them all

https://www.tutorialsteacher.com/csharp/csharp-list

that covers most of it

[worldly reef]

I'm not sure how that does what I want. How would I use that to figure out if the colliders are not just touching but overlapping?

[grand coral]

oh i see

no clue sorry

[lost phoenix]

does any1 know how to make this work

[snow willow]

using UnityEngine.SceneManagement;

Your code editor should be suggesting that for you if you mouse over the error

[lost phoenix]

thanks

also the main menu part is having an error aswell

[late viper]

https://docs.unity3d.com/ScriptReference/Physics.OverlapBox.html

[worldly reef]

Thanks that helpful. I'll have to do some tests and try to figure that out.

[worldly reef]

No worries!

[lost phoenix]

The namespace '<global namespace>' already contains a definition for 'MainMenu'

this

[snow willow]

You have a duplicate script in your project

Two MainMenu scripts

Or at least two scripts that contain: public class MainMenu

[lost phoenix]

oh ok

[obtuse sierra]

My gun in Unity2d gets distorted when I rotate it.
for example, sometimes it'll look like this:

and other times it looks like

obviously distorted

public float speed;
    public Transform gun;

    void Update()
    {
        Vector2 t_direction = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
        float angle = Mathf.Atan2(t_direction.y, t_direction.x) * Mathf.Rad2Deg;

        Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.forward);
        gun.rotation = Quaternion.Slerp(gun.rotation, rotation, speed * Time.deltaTime);
    }```
here's the code (math is not mine), any ideas on how i could fix the distortion?

[snow willow]

this is not caused by your script

it's caused by your object hierarchy containing non-uniformly scaled objects

e.g. the parent of the gun has a scale that is not (1, 1, 1)

[obtuse sierra]

you're the goat fr

how long have you been doing game dev?

[snow willow]

On and off as a hobby for like 10 years

[obtuse sierra]

thats like 65% of my lifespan so far

[dusky wagon]

I have another question. Can I do sort of like overlays for textures? For example I made this game character. Can I make him have different hair colours, hair styles, eye colour, and other visual things, without having to make a sprite for every single possible combination?

[snow willow]

• Make the baseline sprite in greyscale so you can tint it

• Make separate sprites for the base body, hairs, clothes, etc..

[gilded rover]

Pls help, my jump code for a 2d game is not working, I am making a ragdoll stickman sort of game. I can double jump, but I don't know how to prevent from me double jumping
https://pastebin.com/UVKaZNhy

[snow willow]

then you can layer them to make a customizable character

[dusky wagon]

Okay and how does greyscaling work?

[snow willow]

Meaning - only use shades of grey for colors

[dusky wagon]

Yeah but how do I tint it in unity?

[snow willow]

that way it can be tinted

[snow willow]

https://docs.unity3d.com/ScriptReference/SpriteRenderer-color.html

[dusky wagon]

For example if I press a certain button the eyes get tinted to cyan and the rest stays the same

Okay I will look into that in a sec

[snow willow]

yes - you just set the color on the spriteRenderer

but the eyes would need to be a separate sprite

You can otherwise look into like a "color by numbers" shader

that would be a bit more complex

[dusky wagon]

Okay thanks I should be able to do the rest by myself, thank you

[mortal ginkgo]

I know that you were asking for the jump thing but I was also wondering why you are using if movement > or < to move, instead you could just set the velocity of the rb with the movement float like
rigidBody.addForce(movement * movespeed, 0) because then the code also looks more neat if you ask me

[pseudo tree]

hey does anyone here know anything about animating

[elder minnow]

That question is not specific enough

[snow willow]

I know nothing about most things

[tawdry sphinx]

my character has infinite jump

how do I make him stop all online tutorial makes no sense

I did a RaycastHit2D but it doesn't work

[snow willow]

You "did" a RaycastHit2D?

what does that mean?

[tawdry sphinx]

i made one

rather

sorry

[snow willow]

you made it how?

[tawdry sphinx]

bool IsGrounded()
{
RaycastHit2D hit = Physics2D.Raycast((transform.position) + new Vector3(0, -0.1f, 0), Vector2.down, 0.1f);
return hit.collider != null;

}

[snow willow]

Basically, my question, in short is - hjow does your ground check work

or how is it supposed to work

[tawdry sphinx]

well it just checks if it's touching the ground but it's not working

character still has inf jump

[snow willow]

how tall is your character

and where is its pivot

[tawdry sphinx]

pivot?

[snow willow]

seems like the raycast is probably not reaching the ground

pivot

yes

the position of the object

[tawdry sphinx]

my boxcollider?

[snow willow]

the place where the movement gizmo shows in scene view when your editor is set to pivot mode

[snow willow]

no, whichever GameObject this scirpt is attached to

[tawdry sphinx]

how do i set it to pivot mode

[snow willow]

the pivot is where transform.position is

[tawdry sphinx]

i dont see that i just have

[snow willow]

Yeah

it's in center mode

press that button

[tawdry sphinx]

okay

[snow willow]

or press "Z"

then select your player character

and look at where its pivot is

how far is that from the bottom of its collider?

Is it more than .2 units?

[tawdry sphinx]

pivot mode does nothing

im in pivot mode rn

this is what it looks like

im sorry im actually incompetent

i guess the pivot is in the middle

of my player character

[snow willow]

yes

and how bug is the player character

[tawdry sphinx]

1 unit

[snow willow]

it looks like it's 1 unit tall;

so

.1 + .1 = .2

the distance from the center of that box to the ground is .5

so your raycast is not going to reach the ground now is it?

[tawdry sphinx]

that's true

so i have to make the offset bigger on the raycast?

[snow willow]

I guess so

[tawdry sphinx]

so make it 0.5?

or can i move the pivot

?

[snow willow]

Up to you

You can/should use Debug.DrawRay as well to visualize the ray.

[tawdry sphinx]

i'd rather move the pivot but idk how to do that

oh really that's hype

[snow willow]

Is it a sprite?

If it's a sprite, you can use the sprite editor

[tawdry sphinx]

i have a Player empty object and a sprite child

[snow willow]

Oh you can just move the child then

so that it's offset relative to the parent

(also put the collider on the child)

[tawdry sphinx]

oh put the collider on the child

[snow willow]

alternatively - the collider itself has an offset field I believe

or at least it does in 3D

not sure if the 2D one has

[tawdry sphinx]

it does have one but it doesn't help

so

all i have to do is move the offset on the collider for the sprite

?

[snow willow]

play with it

learn it

[tawdry sphinx]

trying man this is hard

[paper yew]

So, could someone help me with my sprite atlas issue?

[tawdry sphinx]

@snow willow but if i move the offset my character is floating

[snow willow]

right - offset the sprite as well

using the child's transform position

[tawdry sphinx]

okay that's good

god this is so annoying

now I can't jump at all

okay new thing

whenever I move my sprite to make the pivot point at the bottom of the sprite

it moves the player (parent of sprite) up with the sprite

[snow willow]

Make sure you're still in Pivot mode not Center mode

[tawdry sphinx]

holy shit

thank you so much

[paper yew]

Do I have to edit the Sprite Atlas file directly?

[tawdry sphinx]

does anyone mind getting in vc or something to help me figure out something

why this doesnt display anything?

[viral moss]

May I suggest using this to check the layer easier?

collision.gameObject.layer == LayerMask.NameToLayer("LayerNameGoesHere")

[gentle phoenix]

Hiii, I have a rigidbody on an image rendering in my canvas. This falls on game load. I want the image to stay within the screen bounds rather than just continuously fall; but when adding an edge collider to either the camera or the canvas the object just falls right through

Anyone know anything about 2d rigidbody/colliders?

[late viper]

does the falling object have a collider?

[gentle phoenix]

oh

That was the secret, thank you

[pseudo geyser]

This are some frames of my character, the base color is white so I can customize the skin tone via the "Color" component in the sprite render, the issue is that when the player got hit or killed the entire sprite should be full white but obviously got replaced by the color I chosed. What can i do?

[outer plume]

Okay so I have a question. I am trying to use a Gizmos.DrawCube() but when I hit play I see... nothing. The gameobject is there but there seems to be no generation going on. I am using the following line (have also tried creating a new vector3 within, at a loss):
Gizmos.DrawCube(pos, Vector3.one);

It is inside an OnDrawGizmos() class so idk what is wrong

[marsh quail]

@pseudo geyser try using a shader

[pseudo geyser]

Yeah I solved with that

[snow willow]

Do you have Gizmos enabled?

[outer plume]

Yes

[obtuse sierra]

so im trying to make a bullet after i fire, and make it fly in the right direction

at the moment, the bullet doesnt do anything at all

it just instantiates and sits there, still

[snow willow]

If you're using FixedUpdate there's no need for Time.deltaTime really

It should work though - just slowly

[obtuse sierra]

so this should be working is what you're saying

[obtuse sierra]

i debugged it and the Z level is going up?

transform.forward is x is it not

[snow willow]

transform.forward is whatever direction the object is facing

which is the local +z axis

[tawny wyvern]

I'm having an issue with this sprite, it's not rendering in front of the 3D models

any suggestions?

[snow willow]

In 2D you normally use transform.right instead of transform.forward

right is the +x axis

[tawny wyvern]

Half of it is inside the 3D model, the other half is sticking out, but I'd like it to show all of the sprite regardless of where it is

[snow willow]

sprites have 3d physical positions and rotations

you need to put it in front of things to show it in front

[tawny wyvern]

So how would I make it always show

[snow willow]

either that or use a custom shader that draws on top all the time

[tawny wyvern]

alright, I'll do that then, thanks

[obtuse sierra]

it does move now but it doesnt shoot in the direction i want

if the bullet is rotated -90 degrees, transform.right should be upwards right?

[snow willow]

depends on which axis it's rotated

and what its starting orientation was

[obtuse sierra]

starting orientation is at 0 degrees, it shoots right

its rotating on z axis i think

yeah 2d only offers z axis

[snow willow]

Then yes if you rotated it -90 then transform.right should now point upwards

I think...

or maybe downwards 😄

nah I think it's up

what's happening instead? How are you rotating it?

[obtuse sierra]

as i instantiate it, i set the rotation to the rotation of the weapon

looks liek this

[snow willow]

I don't see any rotation being set here

just a position

[obtuse sierra]

oh

[snow willow]

Bullet.transform.rotation = transform.rotation;

[obtuse sierra]

changed to this

thanks man

[obtuse sierra]

quick question, to do weapon kickback (like i just wanna have some force on the player the opposite direction of the shooting), i would just get weapon forward and up, and apply the opposite direction on player?

[snow willow]

I think it would be weapon.right for the direction of shooting and therefore -weapon.right for the direction of the recoil impulse, right?

[obtuse sierra]

yeah cool

[remote moth]

exist a way to do that?

    void Update(){
        System.Type x = Upgrade();
        this.gameObject.AddComponent(typeof(x));
    }

    public abstract System.Type Upgrade();

[snow willow]

you don't need typeof(x)

you can just pass x

this.gameObject is also unecessary - the whole line can just be AddComponent(x);

[obtuse sierra]

took a small break, came back, realized that the kickback is off by a bit. any reason for this?

ill show code

last line determines the direction of the knockback

when the gun is pointing straight down, or even further left than straight down, it knocks me to the left

but if i move more it'll fix itself

[snow willow]

because you are doing a recoil to the left/down

(relative to the gun rotation)

[obtuse sierra]

oh

[obtuse sierra]

i still cant wrap my head around this

[snow willow]

Why are you adding Bullet.transform.up * -2f?

[obtuse sierra]

oh its only right

not down at all

is that the solution

[snow willow]

yes

why would you add down

[obtuse sierra]

idk i was thinking polar opposite of where it was aiming

and in my head that included transform,.up

[snow willow]

where it is aiming is directly to the right

[obtuse sierra]

cool

that works a lot better

[snow willow]

Red arrow is transform.right.
Green arrow is transform.up

[obtuse sierra]

yeah i dont know why i was including .up

at least i wont make this mistake again

thanks

does unity 2d point light illuminate 2d objects as well or sprites only

[snow willow]

what is a "2d object"?

that is not a sprite

[obtuse sierra]

sorry i still dont know how to refer to them

[snow willow]

There's SpriteRenderers

and... that's pretty much it

[obtuse sierra]

oh

nevermind

i guess they're all sprites

[prime grail]

So lets say i wanted to add force on Y axis of a sprite when i press "up" on the arrow keys, how would i go about doing that?

specifically using rigidbody 2d

[elder minnow]

@prime grail

float power = 2f;
myRigidbody.AddForce(transform.up * power);

You just have to multiply a variable that is in charge of the "power" of your force by a normalized direction

transform.up is the same as a Vector3 of (0, 1, 0)

You have to register inputs on every frame if you use the old input system, so basically:

private void Update()
{
    if (Input.GetKeyDown(KeyCode.UpArrow))
    {
        // Pressed addforce button
        myBool = true;
    }
}

private void FixedUpdate()
{
    if(myBool)
    {
        myRigidbody.AddForce(transform.up * power);
        myBool = false;
    }
}

There, fixed it*

That's the gist of it

[prime grail]

Ah ok, thank you!

[dusky wagon]

How can you make colliders that can be passed through from one side jut not from the other? So for example in platformer games there are some platforms that you can jump through from the bottom but stand on the top

[snow willow]

saw a really good youtube video about this recently...

https://www.youtube.com/watch?v=M_kg7yjuhNg

[dusky wagon]

Awesome! Thank you

And one more question. How can I make objects that always move between two (or maybe more) points at a certain speed?

So for example have a platform or enemy pending around

If anyone knows feel free to ping me

[cursive heart]

I have a problem where when I instantiate the blocks, they are instantiated in the wrong rotation. Can someone help me?

code:
https://hastebin.com/raw/ewelareduv

[snow willow]

You can pass whatever rotation into Instantiate that you want.

Currently you are passing in the rotation of the GameObject that the Principal script is attached to

If that's not correct - pass in a different rotation that is correct.

[wide ginkgo]

☝️ You can use Quaternion.identity to pass in "no rotation"

[cursive heart]

How can I set the rotation that I want?

[snow willow]

It is the third parameter to Instantiate

[cursive heart]

I tried, but it's still in the wrong position

[snow willow]

Ok what rotation do you want

[snow willow]

first figure that out. Pause your game, go to one of the rectangles, rotate it how you want

and look in the inspector to see what that rotation is

Then you can use Quaternion.Euler(x, y, z) in that third parameter to use that rotation when spawning

that's probably Quaternion.Euler(0, 0, 90)

[cursive heart]

It worked, thank you very much

👍

[mild pewter]

Wow I only just now realized there's a channel for 2d code

[cursive heart]

I made code to move a block in the keyboard in the Z and Y axis, but for some reason, the Y axis I defined is selecting the X axis. What do i do?

https://gyazo.com/21ff7018ec9bac20ba9ff8a7d43f4a98

[viral moss]

@cursive heart Isn't it just because you have it rotated by 90?

[wraith osprey]

anyone know how to ask player's name (string) and after level end or something displays the name and collected gems in a scene?

[viral moss]

Your phrasing's a bit odd but..
If you mean when the level is beaten, you display a UI element with something like
"Player1 collected 30/60 Gems!"

You would need to store the player's name somewhere and grab it at the end of the level, potentially on the player themselves, and then have a counter that goes up everytime a gem is collected.

[burnt badge]

whenever i try to use
image = transform.GetComponent<Image>();
in a base class, it doesnt work, but it does when executing it in a derived class.

[left nest]

I am trying to detect when something collides with a gameObject, this gameObject has a box collider 2D and it is set to on trigger, the projectile I am sending towards this gameObject also has a box collider and it has default settings, I want to detect when the projectile collides with the gameObject so I wrote this code here:

using UnityEngine;

public class Boss_Health : MonoBehaviour
{
    public int health;

    void OnTriggerEnter2D(Collider2D other)
    {
        health -= 1;
        Debug.Log("Oh No I Have Been Hit :( ");
    }

    void Update()
    {
        if(health <= 0)
        {
            Destroy(gameObject);
        }
    }
}

The projectile is moved with transform.Translate, with all of this it is not working and I am not sure why can I get some feedback?

[hollow crown]

physics messages will not work correctly if you move via transform

[left nest]

To be more specific: The debug.log is not showing up in the console

[left nest]

ahh

[hollow crown]

as you are bypassing the physics system

[left nest]

would raycasts work?

[hollow crown]

Sure, or you can use a Rigidbody2D and its functions

[left nest]

ok thank you

so if I moved the projectile using rigidbody physics it should detect the collision?

[hollow crown]

Yup

[left nest]

ok thank you!

[wraith osprey]

anyone have a sample UML diagram of platform game?

where should I place tilemap stuff in it xD

[dusky wagon]

How can you fix graphic errors lime this? They keep appearing and I dont know why

[obtuse sierra]

both objects have a collider (sphere collider2d and box collider2d)

collision never happens?

oh, also the thing i'm trying to collide with has the tag "Object"

[late viper]

what collision method are you using? also at least one of them needs a rigidbody

[obtuse sierra]

oh, did not know they need a rigidbody

will implement

thanks, works now

[light wraith]

Hi, I was trying to make a infinite level kind of game. all I want to do is spawn a bunch of gameobjects on the scene (screenshot of what I'm trying to make). But I dont want to instantiate all the objects randomly right at start (which I am doing right now). Any ideas?

the center circle is my player

this is the code I use

    {
        for(int i = 0; i<=noOfObjects; i++)
        {
            Vector2 pickPoint = new Vector2(Random.Range(-bounds, bounds), Random.Range(-bounds, bounds));
            Instantiate(breakable, pickPoint, Quaternion.identity); 
        }
    }```

[lament spire]

how do you want them to appear then

[remote moth]

where can i do that a text is on a spefify worldpostion (NOT screenpostion)?

[lament spire]

does your game scroll in a direction ?

[lament spire]

Camera.main.WorldToScreenPoint

[remote moth]

should i set the canvas text on this position everytime?

[lament spire]

if you want it to follow something you need to call it every frame on the text object

[remote moth]

but then it is on the screen postion or not?

becaus a canvas text is everytime on the same screenposition

[remote moth]

TextW.transform.position = Camera.main.WorldToScreenPoint(new Vector2(0,0));

and that work?

no work not

[remote moth]

but it work when i do it under update

[lament spire]

Update calls whatever code is inside every frame

Put it in Start() if you dont want it to follow

[simple niche]

im not sure why this always return true bool IsGrounded() { return Physics2D.Raycast(transform.position, -Vector2.up, distToGround + 0.1f); }

distToGround = Collider.bounds.extents.y;

its supposed to check if theres ground underneath the player

[hazy trench]

You should grab the RaycastHit2D returned by the Raycast call, then you could Debug.Log out what it hit

my guess is it's hitting itself or something

[simple niche]

i did this bool IsGrounded() { RaycastHit2D hit = Physics2D.Raycast(transform.position, -Vector2.up, distToGround + 0.1f); Debug.Log(hit.collider); return hit; }

but all its really telling me is that its hitting a boxCollider2D

[hazy trench]

what about hit.collider.gameObject?

[simple niche]

https://i.imgur.com/ywOcKRO.png

[hazy trench]

Yeah so your raycast is hitting the player

You can set the layerMask to make it so your RayCast ignores colliders from certain layers

so if you setup a 'Player' layer you can have the RayCast ignore the player

Or, you could try to set the starting point of the ray below the player

[simple niche]

hmm

now its never true

RaycastHit2D hit = Physics2D.Raycast(transform.position, -Vector2.up, distToGround + .1f, LayerMask.GetMask("Player"));

[hazy trench]

maybe first change the .1f to something much larger

just to figure out if the ray just isn't long enough or something else is going on

[simple niche]

tried setting it to 20 and nothing

[acoustic vector]

@simple nicheInstead of layermasks, you can make a raycast ignore the object that creates it by going into Physics2D settings. You may have better luck with this method:

https://answers.unity.com/questions/756380/raycast-ignore-itself.html

[hazy trench]

that's awesome!

[hazy trench]

Is your ground in the Player layer?

[simple niche]

no

[hazy trench]

You can use Gizmos to draw the ray and then you can see in the editor what the ray is doing: https://docs.unity3d.com/ScriptReference/Gizmos.DrawRay.html

[simple niche]

https://i.imgur.com/5fDyoGC.png

thats the gizmo

[simple niche]

im not sure what combination of things i changed did it but i got it working

thanks

[abstract olive]

@junior vigil Stop crossposting .

[light wraith]

whoops, i'm too late. Yes, the player can slingshot in all directions.
