So if I understand this correctly, you're using two colliders as separate hitboxes and combining that with the bullet's velocity to handle the logic, basically?

[tropic charm]

Yes. I added logic to try to do what you are trying to do. That is, use just one collider. I never finished it but the logic would go into ShowDamage().

[native thistle]

Okay, I think I understand. This has definitely been food for thought; I'll give my code a bit of a refactor and try something closer to this implementation. Thank you so much! 😀

[tropic charm]

Yep. No problem.

@twin topaz Look at this code. Something I just whipped up.

https://hatebin.com/blzhqwqikq

Use it as follows...

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    private CameraZoomHandler _cameraZoomHandler;

    void Start()
    {
        _cameraZoomHandler = GetComponent<CameraZoomHandler>();

        if (!_cameraZoomHandler)
        {
            throw new System.Exception("You messed up.");
        }
    }

    public void Damaged()
    {
        // ...
        _cameraZoomHandler.StartCameraZoomAnimation();
    }
}

[still tendon]

is there any code to make a 2d object face the mouse position?

[bronze estuary]

can somebody help?

these methods are not being called

both objects that are supposed to be colliding have colliders and rigidbodies

and it doesnt even print "test" when the playuer touches the thing

its even in contacts

its in continuios

oh wait ohhh

i need to do full kinematic continuous i think

nopp

im lost

[severe notch]

How to make two objects with rigidbody2D not push each other?

[tropic inlet]

u can find it from google

commonly, u will see atan2(dir.y, dir.x) * Mathf.Rad2Deg used to find the angle in degrees, where dir is a direction vector pointing from the object to the mouse

[still tendon]

ok, thx!

[drifting plaza]

is procedural biome generation possible in a 2d game

[indigo oriole]

Of course why wouldn't it be

[drifting plaza]

how hard is it

[indigo oriole]

Depends what you need exactly

[tropic charm]

using UnityEngine;

public class PointAtMouse : MonoBehaviour
{
    [SerializeField] private float _adjustDegrees = -90.0f;

    void Update()
    {
        Vector3 currentMousePos = Input.mousePosition;
        currentMousePos.z = Camera.main.nearClipPlane;

        Vector3 mouseWorldPos = Camera.main.ScreenToWorldPoint(currentMousePos);

        Vector3 delta = mouseWorldPos - transform.position;
        delta.z = 0.0f;

        float angle = _adjustDegrees + Vector3.SignedAngle(Vector3.right, delta, Vector3.forward);

        transform.rotation = Quaternion.Euler(0.0f, 0.0f, angle);

I have set up a timer that counts how long it takes you to complete a level, It was working perfectly fine yesterday but when I opened my project today it has now stopped working, visual studio shows no errors

the Debug.Log(timePlayingStr); only prints once and then stops

the Debug.Log("update timer hath begun"); prints

Debug.Log(" timer hath begun"); prints

but it only runs once even though it's a loop

nvm I got it to run

[unreal gulch]

Hello, does anyone know how to make cinemachine follow the player that you just spawned?
i tried adding this script to CM Vcam but doesnt seem to work, any help?
code:

[burnt badge]

anyone know how to draw a circle around an object in-game?

[fervent otter]

how do you mean?

[burnt badge]

im making a tower defense game. I want the player to see a slightly opaque circle on top the tower while theyre trying to place it

[tropic charm]

I think the closest thing there is to that is you can create sprites with specific shapes. If you right-click in the asset window you can chose Create | Sprites | Circle.

[burnt badge]

is there a way to do this within the code?

[tropic charm]

No, I don't think so. That feature will basically just create a sprite file (png) based on your design-time parameters.

You might have to find a shader to do that.

[burnt badge]

yeah, im looking at the inspector for it now. I can use this, so thanks jack

[vagrant wigeon]

Hi, so i'm making a boss level and i have to make sure that the boss (when he hits those 3 colliders) enable the Script Renderer. I first thought about using a general script for the holes and then assign it to each of them. But even if i collide with hit it doesn't re-enable the Renderer. Any suggestions?

Here's the hole script

i fixed it

[regal ocean]

hey im new and i can't see what is the problem in this code it says that the name Destroy doesnt exist

but i just want to destroy a game object every time my player step on it

[vocal condor]

Destory != Destroy

[peak stirrup]

I have set up checkpoints along the platform, basically they teleport an empty object to them, which the player teleports to when they "die". for some reason when you die after hitting a checkpoint, you get teleported to the second one, i'll post code below

they both have the same script attached to them but with a different flag gameobject

does it have to do with instance? I am still not enirely sure what insatnce does, only that using it I can reference my class in another script.

nvm, I changed it so that it moves checkpoint to the players position when they enter the collider

[twin topaz]

yo guys i am making a simple bow game and i want the bow to hold at its apex and i made a animation for it but the problem i am running into it shoots before i hold the mouse button down(and the button doesn't even needs to be held down for the holding animation to play), it also does the shoot animation before the hold animation

[craggy kite]

How are you calling the animations?

[twin topaz]

are you talking about the script or animator?

if animator i set them as a trigger parameter

[wanton iris]

Anyone here have any experience with the pixle perfect camera?

I will ask my questions anyway 🙂 : my project is using 16x16 tilemaps / sprites

so i set my Pixle Perfect camera's assets PPU to 16 and left the reference resolution to 320x180

and calculating the size of my camera, I used the formula Y / PPU / 2 : (180/16/2) : 5.625

but that made my view waaaay to small

but it seemed to work if i times it by 10 : 65.25 (looks about right for screen size when playing)

hmm, my follow up question was, that my camera size kept changing when i hit play

but right now, its not changing, not sure what changed...

oh, nm, sorry for wall of text, if i disable the pixle perfect camera, my camera size stays at 56.25, but if i enable it, it changes it to 10.8125

not sure why

[rancid gorge]

On the topic of Pixel Perfect cam, anyone ever figure out how to get rid of the Pixel jerking when cam is following the player character?

[tropic charm]

@naive epoch I don't see any problems but I also don't understand what it is the script is trying to accomplish.

It looks like it is finding game objects with a tag of "Player" and will rotate to face them but I'm not sure what it is supposed to do when there is more than one player.

It looks like you have most of what you need. One approach would be to iterate through the players each time Update() is called and track it. You can determine the distance between a player and the 'tracker' by subtracting the two transform.positions and reading magnitude property of the result.

[tropic charm]

I think you should be able to do what you are doing in ExcludeSelfRotationTarget() now.

[stark totem]

Heya, i've ran into small problem with tilemaps, while trying to place second layer of tiles via Tilemap.SetTile() they are weirdly offseted (pic rel). I've tried changing pivot of sprites, but then when i try place those tiles by myself they are offseted

[vocal solar]

Movement in 2D without gliding?

Anyone?

If I press W once it glides away like its on ice skates

and then stops after certain time

[stark totem]

Okey so i found out that i need to change Matrix4x4 transform on y value to 0.5

[orchid pewter]

how do i stop my character from sticking to walls instead of just falling straight down?

[tropic inlet]

those animations are so cute

anyway, I fixed this issue by adding a physics material to my rigidbody2d iirc

[glass coral]

Hi.
I, m programatically adding an image to a sprite rendered.
The image is 106px/106px, so i set the px per unit of the sprite to 106

When i place my sprite i the scene the size of it is 1
But when i create a SpriteRenderer with a script the size of the images goes brrr

Any ideas ?

[orchid pewter]

i've got no materials 😦

[tropic inlet]

u can create one in 1 second

right-click in ur assets

give it any name

slap it onto ur collider or ur Rigidbody2D (i don't remember which one)
see if that changes anything

[orchid pewter]

you're talking about physics materials?

[tropic inlet]

idk what it's called exactly

just see ur collider/rigidbody2d fields for ideas

[glass coral]

ok i'm the dumbest.. i didn't put the right number in the creation of my sprite

[orchid pewter]

@tropic inlet make one of these?

[tropic inlet]

sure

[orchid pewter]

what do i change?

[tropic inlet]

i don't know; I haven't touched Unity in ages
just experiment

slap it onto a collider/rigidbody2d, see if it fixes wall thing

[glass coral]

surely friction

dynamic one

[orchid pewter]

oh wow that was really simple lol

thank you

created a physics material 2d with 0 friction and it works

you only get two values lol

i wish i could change the box collider with values instead of eyeballing it

[tropic charm]

Use Input.GetAxisRaw() instead of Input.GetAxis().

[snow willow]

You must configure your Canvas Scaler as desired

Looks like you currently have it set to Constant Pixel Size

which means... basically no scaling happens at all

Try the other options 🙂

[misty hazel]

hey guys so im stuck and have been for a while and it made me put down the project but i want to finish it

i have this code ill link (hastebin not working)

and the idea is itsll move a gameobject (enemyship) in a random direction for a stay and after so meny seconds change direcection

then i made it change direction if it hit a box collider but the change of direction sometimes is the same and it make the ship stutter

i want to to move towards the player and or away from the play at a random time but also keep away from the box collider i have names (enemywalls)

but im very stuck

i dont know if im looking at this all wrong or not but i really need help

ill post the code next

{
    public float latestDirectionChangeTime;
    private readonly float directionChangeTime = 5f;
    private float characterVelocity = 2f;
    private Vector2 movementDirection;
    private Vector2 movementPerSecond;

    
    
    void Start()
    {
        latestDirectionChangeTime = 0f;
        calcuateNewMovementVector();
    }

    void calcuateNewMovementVector()
    {
        //create a random direction vector with the magnitude of 1, later multiply it with the velocity of the enemy
        movementDirection = new Vector2(Random.Range(-1.0f, 1.0f), Random.Range(-1.0f, 1.0f)).normalized;
        movementPerSecond = movementDirection * characterVelocity;
    }

    void Update()
    {
        //if the changeTime was reached, calculate a new movement vector
        if (Time.time - latestDirectionChangeTime > directionChangeTime)
        {
            latestDirectionChangeTime = Time.time;
            calcuateNewMovementVector();
            

        }

        //move enemy: 
        transform.position = new Vector2(transform.position.x + (movementPerSecond.x * Time.deltaTime),
        transform.position.y + (movementPerSecond.y * Time.deltaTime));

    }

    void OnCollisionStay2D(Collision2D collision)
    {
        //moves the enemy ship away from wall if it colliders with "enemyWalls" (box collider)
        if (collision.gameObject.tag == "enemyWalls")
        {
           calcuateNewMovementVector();
        }
    }


}```

[still tendon]

Is there a way for me to tell how much force an object has pushing against another object without using velocity?

How do i add physics to the blue cube?

[tropic charm]

Add a RigidBody2D component to it.

[still tendon]

Oh ok

Thx

[tropic charm]

Look into Physics2D.Raycast(). You can use it in calcuateNewMovementVector() to look in the direction you intend to turn to and check to see if it is clear of walls or not.

[still tendon]

i did but the cube is going down and not stoping

[tropic charm]

The cube doesn't have anything to interact with. The ground will need to be a rigid body as well.

[still tendon]

oh

so i basically need to a add a rigid body to both of those three?

[tropic charm]

Actually the ground can just have a box collider on it. If you haven't put one on the cube then it will need one too.

[nocturne rivet]

can you add a physicsmaterial2d at runtime?

[snow willow]

yes

[tall current]

I'm using velocity to move my character, and that works awesome in almost every way.

There's a visual problem. The character stutters forward as it moves.

This is the code for moving the character horizontally, but I don't think it has to do with that.

private Vector2 VerticalMove(Vector2 vel, float speed)
{
    return new Vector2(myIn.move.x * speed, vel.y);
}

I believe it has to do with how I set the velocity. I do it at every FixedUpdate()

Does anyone know why this kind of stuttering appears?

I believe it has to do with the order of Unity's order of execution, I'll try something else...

nope, tried doing it at WaitForFixedUpdate but the stuttering continues, any ideas?

[deft niche]

anyone got an Drag and Drop Script?

[tropic charm]

You might see if this fixes your issue...

[still tendon]

i have a problem here

i've added my ground check and all to my cube but i added it in to one side

but when my cube rotates to one of the other three sides when i press Space the cube doesn't jump

really need help on this

[stark totem]

Heya, i was wondering is it possible to make pathfinding and movement system based on Tilemaps?

I can't find any reasource for that, so if i missed something i would really appreciate sending me tutorial or something

[twin topaz]

yo how do i change the position of something else(different object) after an object has been hit

[tropic inlet]

GameObject otherObject = ...;
otherObject.transform.position = ...;

[twin topaz]

i don't think that will work?

[tropic inlet]

It will work.
Assigning to transform.position is how you change the position of an object.

Just make sure otherObject stores a reference to the object you need to reposition

[tall current]

Aye mate, thanks a lot. Forgot about that completly :D

[still tendon]

can i have a script for the camera following the character?

i'm following these tutorials but it's not just working on point

[tall current]

I can give ya one, 2 sec...

[strong heron]

Camera.transform.position = target.transform.position

@still tendon this should work on the most basic level

[tall current]

~~https://hatebin.com/mvsekrqbqr~~
https://hatebin.com/kzaldfgyqj
Here's one that I've been using for a few of my 2D games @still tendon

0.01 is a good value for smoothing speed, play around with it to find the correct one.

And set the offset of z to the offset you have on your camera, then you're fine :)

[still tendon]

thank you leo and Mazarch so much

[still tendon]

tysm

[still tendon]

i don't know how to put this correctly van you help me?

[tall current]

offset.z = -10 probably, or whatever your offset on your camera is.

oh wait, is it 2D?

[still tendon]

yea]

[tall current]

oh, we're in #🖼️┃2d-tools hah

[still tendon]

well you said 2D here lol

[tall current]

:D

well .z should be -10

and the player should be target

that should work...

[still tendon]

ok it's working thanks

[violet basin]

hey guys, i'm having an issue with this problem : I have this dash function attached to my game object A. I allows A to go from point 1 to point 2. I would like my game object B (children to A) to rotate through Z axis according this angle :

[limber thistle]

The rotation from the black line to the dash direction is :
Vector2 blackLine = Vector2.down; float angleToDashDir = Vector2.SignedAngle(blackLine, dir); Quaternion rotation = Quaternion.AngleAxis(angleToDashDir, new Vector3(0,0,1));

@violet basin

[violet basin]

thanks a lot, i'll try that 🙂

[twin topaz]

@tropic inlet so what about otherObject.transform.position = ... what do i put where the ... is supposed to be

[strong heron]

@twin topaz that would probably be a vector3/vector2 position that you want to move the otherobject to

[tight tinsel]

How do i get the direction of the collision

[strong heron]

@tight tinsel you could probably use a ContactPoint2D if its a non-trigger collision and then compare the position of whatever gameobject you need the relative direction from

[crystal geode]

is it possible to trigger animations based on a variable in my character's controller script? My character has a 'state' variable that will change to "standing" or "walking" or "jumping," and I wasn't sure if there was a way to use that variable to trigger animation transitions

[tropic inlet]

You said you wanted to change the position of an object, correct?
You must know what coordinates you want to change its position to, then, right?

just replace it with new Vector3(...)

with ur desired coordinates replacing ...

[twin topaz]

yea but i want it to change position every time a object is destroyed

[strong heron]

@crystal geode not sure if this is what you meant but you can trigger animations using parameters in the animator and then setting the parameters through scripting using Animator.SetInteger or the corresponding variable

@twin topaz use it in the OnDestroy() function

[twin topaz]

@strong heron i would have to create a new function for Ondestroy right?

[strong heron]

@twin topaz So you could really put it on any script that is attached to the gameobject that will be destroyed and trigger the function

OnDestroy() is built in so just go

OnDestroy() { otherObject.transform.position = target.transform.position }

[faint creek]

how can i set the player as platforms child on collision

i have half of it figured out but the rest no

[strong heron]

Under OnCollisionEnter2D, you should be able to use player.transform.SetParent(collision.transform)

@faint creek

[strong heron]

is it workin?

[faint creek]

no

[strong heron]

also you probably wanna check if it's the platform you are colliding with

[faint creek]

thats what ive been stuck on i have no idea how to do to

[strong heron]

so is the platform a part of the tilemap or a separate object?

[faint creek]

oooh wait

i forgot to give the script to the player

[strong heron]

hehe

happens all the time. if the platform is a separate object you can simply tag it and check against the tag with if(collision.collider.tag == "Platform"){ setparent }

or use the comparetag method which is preferred im told

[twin topaz]

okay i have a problem where it doesn't detect the game object in the script

[crystal geode]

that worked, sorry for not getting back to you. I created an int parameter in my animator and basically had it correspond to an array of "states" in my controller script to tell it which animation to swap to

[faint creek]

Still doesn't work

[orchid pewter]

is raycasting to a layer the only method for detecting if the player is grounded for a 2d platformer?

[strong heron]

@faint creek have to ask, are all your colliders set up properly? sure none are missing or set to triggers?

[faint creek]

The player is

[strong heron]

OnTriggerEnter2d then

[faint creek]

Set to trigger

[strong heron]

OnTriggerEnter2D

@Nivrtap this might be more than you need dependent on your scale but machine states and transitions can be setup in conjunction with the method you're using to have better control, you could potentially create independent 'behavior states' for running jumping etc. and have the transitions called on entering or exiting these states

@crystal geode

[faint creek]

what do i put here

[strong heron]

Collider2D instead of Collision2D

[faint creek]

oh ok

[strong heron]

also make sure you actually gave your platform a tag that says Platform

[faint creek]

Done

[strong heron]

you can also just do collision.tag

let me know if it works

[crystal geode]

ooh, that's definitely something for me to look into. Honestly I'm not even sure if my method is particularly good, but since I need to give or remove control from the player during particular times, using a string to track the current state seemed like the easiest route

[strong heron]

I'm still pretty new so I haven't even used machine states yet. My animator script for my current project is a horror show lol Working code > optimized code that hasn't been written

[twin topaz]

okay i have a problem where it doesn't detect the game object in the script

[faint creek]

semicolone

[faint creek]

do i have to put trigger on the platform

[strong heron]

my girlfriend said I don't smell as good as usual, i told her today I'm only wearing my semi-cologne

no you do need a collider but not a trigger

[faint creek]

haha

ok

well it still doesn't work

[strong heron]

did you try debugging and seeing which part isn't being triggered?

[faint creek]

when they collide it stays as its child

[faint creek]

what?

[strong heron]

wait i thought you wanted it to be set as a child?

[faint creek]

wait let me explain

[strong heron]

if it is a child already and you want it to separate, SetParent(null)

[faint creek]

i have a platform that moves left and right repeatedly i want the player to move with the platform when it jumps on it

[strong heron]

oh i see

this is definitely not the best way to achieve that and potentially causes you problems down the line

[faint creek]

sorry for been unclear

[strong heron]

no worrieds

[faint creek]

oh

[strong heron]

so right now i assume your player just passes right through it?

[faint creek]

no

[strong heron]

because their collider is a trigger?

[faint creek]

the players collider is a trigger

[twin topaz]

Same problem

[faint creek]

but not the moving platforms

[rare yarrow]

Hey so i am trying to make a random dungeon and these errors keep showing up and the error isnt on microsofts website any help here is the code https://hatebin.com/psezcgwwrq and here is the errors any help?

[strong heron]

@rare yarrow It says right there, you are trying to use 2 incompatible arguments

[rare yarrow]

and i dotn knoe how to fix?

pls help

[strong heron]

You are probably trying to set a rotation to a transform.position or other Vector3

@rare yarrow if you double click on those errors in the unity window it should take you to the line in visual studio where your errors occured. failing that just go to the lines listed manually and check it out

look for anywhere you are using a quaternion and make sure you are using it correctly

[rare yarrow]

it turns out i forgot to put in two lines of code lmoa

[still tendon]

no one can help me?

[tropic inlet]

Plenty of people probably can

[strong heron]

...what was the issue?

[leaden hill]

Not really a code issue, but I can't seem to increase the y value of this 2D box collider. It's stuck, and manually increasing it does nothing.

Nevermind I see what's happening. It's a plane that I've rotated around the X-axis, and therefor the Y value is pointing upwards

[distant pecan]

if you post your problem, a lot of people can

[twin topaz]

yo bro can you tell me how to move a object relative to its position so if i have a object at -15 and i want to move it 2 back it would be -15 -2=-17 how would i script that

[strong heron]

Bow.transform.position = Bow.transform.position - new Vector3(0, 0, 0)

With the new vector3 being the distance you want moved

[twin topaz]

why vector3 and not Vector2

@strong heron

why is it (0,0,0)

[strong heron]

Because I don’t know the values you want

[twin topaz]

ah

why vector3?

[strong heron]

Because I don’t know if your project is 2d or 3D

[twin topaz]

ah

[spring zephyr]

*NVM found it myTilemap.GetTransformMatrix(Vector3Int).rotation
So i know i can use map.cellBounds.allPositionsWithin) to get the positions of the tiles in a tilemap, is there a way to get the rotation of a tile?

[still tendon]

I need help in this idk why my cube can do that jump can you guys help me fix it?

[still tendon]

@still tendon did you use AddForce for jumping

adding to velocity usually works better for me

yep i added force

but idk why is not working

Guys I want a bird's eye character to look at the mouse

But I don't know how to do that

If U tell me pls ping me

Well, to start with, I have a spawner that spawns my objects (meteorites and coins) from right to left between the values of the size of my map, i.e.: minY = -1.13 and maxY = 1.13. With the current script, I get a spawner like this :

Can someone send moving commands in 2019.4.18f1
2d

[eternal kraken]

What do you mean moving commands?

[tall current]

you can post problems here...

[still tendon]

@distant pecan

[faint creek]

how can i add double jump to a script that has only one jump

[strong heron]

Make a book like hasAirJumped, then make it execute the jump and set the book to true if input is jump and isgrounded is false and hasAirJumped is also false. Then reset the book to false when you collide with the ground

@faint creek

Bool*

[sleek pivot]

guys why isn't Debug.Log("left") being called? I feel like i'm missing something obvious here I figured it out

The pivot/degrees float is over 90, at wich point it should call "left", why doesn't it?

[faint creek]

in which script

[strong heron]

the bool itself and the execution of it would prob be in the second one, but making it false again on collision would go in the first one @faint creek

[faint creek]

ok

[faint creek]

Im so sorry but could you explain a bit more detailed

[orchid pewter]

is raytracing the most popular method for ground checking?

[abstract olive]

If you mean raycasting, then yes.

[orchid pewter]

wait

[abstract olive]

It's definitely the method which gives the most flexibility.

[orchid pewter]

oh i mean raycasting haha

raytracing is GPUs lol

[abstract olive]

Raytracing is for lighting and rendering.

[orchid pewter]

yeah

i have a quick unity problem, im using 2 text fields and when each one gets updated it convert the text to an int and when you press a button generates a random number between both text fields int (x and y) but unity is sending a lot of weird errors

[tropic charm]

@terse thorn You need to be using the so-called Dynamic string version of the methods. This way you actually get the string that the user entered instead of what you specified at design-time.

[terse thorn]

so i change the void OnXChanged(string x) to void OnXChanged(Dynamic string x)?

[tropic charm]

Look at the popup from your last screenshot. You will see it is divided in two. The top half shows the so-called Dynamic string methods that you can use. Use the OnXChanged() or OnYChanged() from there.

[tropic inlet]

@faint creek Honestly, just make these members

public int jumpsAllowed = 2;
int jumpCount = 0;

and in ur if statement for jumping use jumpCount < allowedJumps

set jumpCount to 0 every time u land. Add 1 every time u jump.

[opal socket]

hm?

Too vague, sorry

[tidal scaffold]

Hey guys! Moving this from #💻┃code-beginner to this channel, since it's 2D related...I have a Kinematic Rigidbody2D and to prevent it from moving through other Kinematic Rigidbody2Ds I currently use this piece of code that utilises BoxCast and nulls the velocity according to the hits "direction":

var bounds = _boxCollider2D.bounds;
var hits = Physics2D.BoxCastAll(bounds.center, bounds.size, 0, Vector2.zero);
foreach (var hit in hits.Where(hit => !hit.collider.Equals(_boxCollider2D))) // ignore self
{
    if ((_velocity.x > 0f && hit.normal.x < 0f) || (_velocity.x < 0f && hit.normal.x > 0f))
    {
        _velocity.x = 0f;
    }

    if ((_velocity.y > 0f && hit.normal.y < 0f) || (_velocity.y < 0f && hit.normal.y > 0f))
    {
        _velocity.y = 0f;
    }
}

Could I get some feedback on this? Is this a good approach? I feel like there has to be a better way to block the movement than those if conditions...

[snow willow]

I think ideally you would just limit your movement such that you end up touching but not intersecting the nearest obstacle in front of you that is within one physics frame of your current velocity

[tidal scaffold]

How would I go about doing this?

[snow willow]

you have to know your own size

then you just move to the position where your raycast hit the obstacle, but offset by your own size

so imagine you're a sphere with radisus 1

you do a raycast and hit an object that is 2 units away

then you would position yourself at that hit position

• 1 unit for your own size

back in the opposite direction of your raycast / velocity

[tidal scaffold]

I'll give that a go thanks for your feedback! 🙂

[sand hemlock]

Hey. I have a game where the Enemies are Scriptable Objects. If I have 3 wolves of the Scene they're all "Wolf" ScriptableObject. Is there a way for me to keep track of which specific enemy this is AND relate it to their physical location on the map consistently? Like can I just somehow, for the meantime, rename the Wolf ScriptableObject like StringName or something to "Wolf2" and then give it it's position or?

[still tendon]

how to fix this?

[inland jacinth]

While it's possible to use ScriptableObjects in this way, I would not recommend it. Do you not have any game objects that represent these enemies?

[sand hemlock]

Nah. I have the scriptableobjects of each enemy instantiated in a list, and the enemies contain their position in my battlefield, but their representation in the visual world isn't associated. I was just going to instantiate it and then associate it with a list of like a class doing similar to what I did.

My game looks kind of like smt, but the visual positioning is important

So it looks like this

And imagine the characters up there are enemies

[inland jacinth]

Is it going to be 3D? (doh, we're in the #🖼️┃2d-tools channel)

[sand hemlock]

Their position though visibly there is important

Nah, 2d.

Sprites on sprite BG

[inland jacinth]

How do you intend to draw them in their positions?

[sand hemlock]

So I was thinking of dividing up the positions based on the size of my battlefield. So my battlefields are a matrix of spaces. 2 rows, and the X columns.

[][][Enemy][][]
[][][][Player][]

Kinda like that

I was going to have some Enemy GameObject that holds the sprite that is based on a fixed location related to the spots. So maybe each spot is 10 wide and the enemy sits center. When they move, the are pushed 10 left or 10 right and the spot they have decides where they exist in space then.

So maybe position 3, translates to 30 in the visual realm or w/e

For extra enemies though probably just copy the base EnemySpriteGameObject and move/rename it.

[inland jacinth]

If the different characters are all very similar and predictable with only trivial differences between them, like what sprite they're using, that approach would work

But it makes things like having something like custom materials or multi-sprite characters more difficult to do

[sand hemlock]

Yeah, I know. I just dunno how else ide do it

They don't literally need to be attached so I could always just

Clear the battlefield and rebuild the enemy locations visually from their position

But then ide potentially be destroying a game object and making it every turn

Which, turn based, so doesn't happen often, but still

[inland jacinth]

There are ways to draw things manually without game objects or renderers, but I don't have experience with that in 2D.

Technically, it's all 3D. The 2D stuff is just flat quads.

[sand hemlock]

Ah, aw. Ya was gonna sau

Wouldn't the method be similar? How would you do it?

[inland jacinth]

Well, sprites can have their own generated mesh

[sand hemlock]

If you had a scriptableobject with the "position" of the enemy, and it contained its sprite

[inland jacinth]

I don't think you can access that mesh, so you'd always have to use the less optimized quad

The mesh is more complex, but smaller because it wraps around the sprite, decreasing its screenspace

[sand hemlock]

Hmm

[inland jacinth]

Sprite atlases also complicate things

I don't think I'd recommend this approach

[sand hemlock]

Aw. I didn't want my sprites to be complex else than bosses. I'll animate those

[inland jacinth]

Also because of the point I gave earlier. It limits what you can do.

Instead, I would just make prefabs for each character/enemy.

There definitely is value in having a sort of ScriptableObject database of every character and common data between them

[sand hemlock]

The only crazy things my sprite needs to do is have things like squash and stretch/jitter/flash for certain attacks that hit them visually.

So you would have a scriptableObject base and then put that into a live game object prefab for each enemy?

[inland jacinth]

I've never made a game that works like this, but I've never really made a 2D game in Unity.

[sand hemlock]

Interesting. I guess I'll just have to study/experiment more at the end of the day.

Hmm, there's maybe a solution out there I haven't seen yet so

Just gotta explore more

[inland jacinth]

While there is value in the ScriptableObject database approach that you're going for, it also limits what you can do

[sand hemlock]

But you did make me aware of some of the pitfalls it feels so thank you for that.

Yeah it does.

[inland jacinth]

My approach would be more dynamic. Just a prefab for every character with a sprite renderer, probably some common scripts that stores data about each character.

Maybe some custom scripts for more custom characters like bosses

They can still all have one common script among them, like Character, which has all the common data like their grid position, health, whatever

And skip the whole scriptable object thing

[sand hemlock]

Hmm sounds like a good idea maybe. Ide still have issues though then with dungeon generation since I'm, again, using ScriptableObject info for its generation, but I could still probably ref the gameobjects in it.

[inland jacinth]

I've also seen some people use ScriptableObjects just to store the data, but have scripts that reference the ScriptableObjects. So all the Wolf game objects would reference the same "Wolf" scriptable object.

[sand hemlock]

Yeah. I'm thinking that might be what works.

[tight tinsel]

How would i get a trigger to tell me when its no longer in contact with any object

[uneven shuttle]

You could cache all collision in a list OnTriggerEnter and remove them on OnTriggerExit, and fire an event when the list is empty. Alternatively, you can set a flag to check for colliders OnTriggerEnter and then use Physics.OverlapCollider(...) on Update, firing the event and stopping the check when nothing is found. There might be more or better options

[stark totem]

Heya again, i have problem with getting tile by clicking mouse on tilemap. So the problem seems to be that somehow mouse position is weirdly converted to grid position for example when i click [-8, -5] unity tells me that i clicked [-8, -6]. World pos is where i clicked, tile pos is designated tile and cell pos is what position in world cell is

here's code

if (Input.GetMouseButtonDown(0))
            {
                Vector2 mousePos = Input.mousePosition;
                var gridPos = Camera.main.ScreenToWorldPoint(new Vector3(mousePos.x, mousePos.y, -10));
                var tile = groundMap.WorldToCell(Vector3Int.FloorToInt(gridPos));
                TileBase tilebase = groundMap.GetTile(tile);
                bool a = dataFromTiles[tilebase].walkable;
                Debug.Log("Tile: " + tile + " TileBase:" + tilebase + "Walkable: " + a);
                Debug.Log("Tile pos: "+ tile);
                Debug.Log("World pos: "+ gridPos);
                Debug.Log("Cell pos: "+ groundMap.CellToWorld(tile));
            }```

[remote abyss]

Try to do just this one-liner grid.WorldToCell(Camera.main.ScreenToWorldPoint(Input.mousePosition)); and see if it returns correct results. Not sure why you do the -10, or the FloorToInt.

[stark totem]

Camera is on z -10

Does the trick, why it's happening tho?

Seem to be problem with FloorToInt(), thanks for help

[snow willow]

If camera is on -10

You want +10

Hey guys, im doing a game which is a 2d turn base 1player vs 1 player. Each player chooses 3 characters from a pool of multiple characters. I did the characters using scriptable objetcts. I want each character to have 4 skills(skills are just click on them and click on the oponent you want to use it on) and a passive, each skill i think its going to be a function because they all do diferent stuff ( some are similar).
My question is how do i "associate" 4 skills to each character ? What do you guys think its the best way, thanks in advance!

Hey! I am making a game, I need to make the object make a sound when it falls. I made a code like thism, but it doesn't always work.

[zenith saddle]

Hello everyone, I am with such a question to you. I wrote a game for an engineering thesis and everything works fine on Unity. However, if I build a project and run the game, it sometimes happens that my character will lose despite having 2 lives. In the code I write that it only has to take 1 and sometimes it will take 2 and I do not understand it. Someone can explain this to me?

sorry for comments in code, my language is polish

[upbeat igloo]

What is the best / simplest way to make a moveable / pushable object in a top down tile set made game?

[distant pecan]

you can just add a rigidbody/collider then change its mass/friction, or you can make a script that whenever the player is colliding with the object, and press a button, the object becomes a child of the player, then decrease player speed if the object is heavy, and things like that

i personally would go with the second option, as it looks better and it's easier to customize

[upbeat igloo]

ah okay and if both my player controller and the object have rigidbody collider I can set how they react when they contact? (aka physics or pushing)

[distant pecan]

you can set a bool to true/false when the player collide with the object

then have a button for pushing it, or check in the movement if this bool is true

using OnCollisionEnter2D/OnCollisionExit2D/OnCollisionStay2D

[upbeat igloo]

amazing ty 😄 gonna try to make a simple puzzle arena with pushing objects and loadzones for new levels

[brisk flame]

make a character class and an ISkills interface that way you can implement different methods for different characters and still call them using the same pattersns

[twin barn]

Is there a way to skip to last scene from any scene?

[strong heron]

Hey all, quick question - I'm using a Tilemap Collider combined with a Composite Collider. Is there any way to eliminate or reduce the vertices you can see going out diagonally from the two right corners?

[snow willow]

Use BoxCollider2Ds instead?

[strong heron]

@snow willow I guess I technically could, and it would probably work. I guess I was just hoping to avoid having to set up independent box colliders for the whole tilemap. I managed to reduce the amount of vertices using some of the Composite Collider2d params but they are still there a bit

[snow willow]

PolygonCollider uses traingles

you can't get rid of these vertices basically

I think 🙂

then again I see some trapezoids in there so maybe I'm talking out of my ass

[strong heron]

That's what I'm saying, if they were all traps I'd be golden

[snow willow]

does it matter really? Are you having issues or just being a perfectionist?

[strong heron]

it's only because my 'carry' mechanic has the item slightly above his head when holding, and when he throw it it will get caught between in the vertices of the topmost facing part

if there is no vertice there it will just gte immediately clipped/pushed back out of the collider

Maybe extruding the edges a bit would help overlap them? @snow willow

[glass coral]

Hi all, how can i find a VerticalLayout width and height (in unity units), i tried vertLayGroup.minWidth but it didn't seem to work

[tropic charm]

You might put the following code at the beginning of OnCollisionEnter2D(). This should prevent the problem you are seeing.

if (this.enabled == false)
{
    return;
}

[topaz dune]

Can i get a basic rundown on the code that i need to get the game up and running? I cant get the camera to be locked onto the player and i cant control the sprite that i want to be the player either

[old sail]

New to tilemaps here. I was originally thinking that my enemy tiles would act as game objects that would be able to move/pathfind around the map, but am I understanding it correctly that tiles on a tilemap is more for drawing the environment of a game? And any mobile object should be a gameobject spawned on top of the tilemap?

[echo cedar]

Hello friends, does anyone see why this wouldn't work, no crash but the method attached to the event handler from the button click never gets called..

GameObject charHud = Instantiate(charHudPrefab, transform);
charHud.transform.Find("Skill1Button").GetComponent<Button>().onClick.AddListener(()=> OnSkillSelection1(unit)); 

private void OnSkillSelection1(Unit unit)
 {
   throw new NotImplementedException();
 }

[snow willow]

should work - are you sure you're clicking the right button?

[echo cedar]

Yeah! For sure haha, I don't have too many buttons yet. It's driving me nuts @.@

[snow willow]

Maybe once the game is running try manually attaching a function and see if it still gets called

maybe it's an issue with graphic raycaster

or missing event system or something

[tropic charm]

@echo cedar You didn't delete the EventSystem from your scene hierarchy did you?

[snow willow]

or some other UI element blocking the click

Also check what the EventSystem says in its preview window when you are mousing over the button. It should tell you if something else is blocking the button.

[echo cedar]

I did not delete the event system. Where is the preview located when I'm hovering the button?

Oh I had it shrunk I see, sorry

[glass coral]

Instead of a Button you can use the OnGui, with a TextArea on a singleton with a public string corresponding to the TextArea. Like this you can debug directly from the code, no need to add buttons. When you instantiate objects from code it's really useful

[tropic charm]

Check out these videos. https://youtu.be/44djqUTg2Sg https://youtu.be/2jTY11Am0Ig

[snow willow]

yeah but this is the old ineffecient GUI system that is much harder to edit :/

[echo cedar]

So I see pointerEnter is on a text box, but when I click it does say pointerPress: the button

does pointer enter also need to say the button?

[tropic charm]

You are correct about both of your assumptions.

[snow willow]

nah you're probably good - is the button's transition graphic also playing?

[echo cedar]

Yes, the transition of a slightly darkened square happens when I click.

[old sail]

@tropic charm Thanks for clarifying!

[glass coral]

Not at all, that's a Immediate GUI system, but with fewer possibilities than the original C library. The same system is used by unity (menus, etc...). The specificity of these UI is that it is computed every frame. It's the perfect tool for debugging. That's literally used everywhere

https://github.com/ocornut/imgui

I think the real UI of unity is a derivate of DearImgui

[snow willow]

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

The IMGUI system is not generally intended to be used for normal in-game user interfaces that players might use and interact with. For that you should use Unity’s main GameObject-based UI system, which offers a GameObject-based approach for editing and positioning UI elements, and has far better tools to work with the visual design and layout of the UI.

yes it's still the primary tool for editor code

[glass coral]

yes it's for debugging, but it's a perfect tool for this

[echo cedar]

It's working? I didnt change a damn thing

LOSING MY MIND

I should write this ?

[tropic charm]

[glass coral]

Do you know how to do a MoveTowards but i want a curve ?

Is it pre-built or do i need to do transform.position updates with a custom function by myself ?

[snow willow]

Not really built into Unity but there are free tools which will do stuff like this: https://assetstore.unity.com/packages/tools/animation/dotween-hotween-v2-27676

[glass coral]

Wait.. I LOVE THIS, you can do custom timelines !

Btw for the moment i create a script for each animation type, then link them with a Chain of responsability to do the full anim. I think it's a bad way to do it.

Hey i wanted to ask what im doing wrong. Im using brackeys Scene Transition tutorial together with my code.

[sweet swan]

capitalize SetTrigger

and pass in the build index of the scene you wanna load

you can find the loadindex by pressin ctrl-shift-b

[compact gate]

Hi, I am incrementing my position each frame by a value, let's call it X
When X = 1, my position increase by 1 each frame and it's perfect
Now when X = 0.1, my position increse by 0.1 each frame but I get some decimal for no reasons
Like going for 5.4 to 5.49999

[sweet swan]

yep, floats be like that

[compact gate]

That's really problematic because my system need to use correct coordinate, I think I will just round these values ?

[sweet swan]

i suppose you could use this as well https://docs.unity3d.com/ScriptReference/Mathf.Approximately.html

[compact gate]

That's quite annoying, I guess it is the famous floating point precision

[sweet swan]

mmhhmm

one alternative is to use integers to track position

but divide them by some arbitrary number like 1000 when youre actually setting positions

so when youre comparing coordinates, you can use the integers

[compact gate]

And when settings transform i divide it ?

[sweet swan]

but ideally you should find a solution that doesnt involve equality comparisons on positions

yepp

[compact gate]

I don't think I can do what I want without that; I need to check if 2 positions are "glued"

I will try to make a better system which will use integer as positions for comparaison

I think it's the best solution

[still tendon]

Hey! Im trying to stick my character onto a moving platform but it isn't working as i thought

I got the code off Jason's video on yt

private void OnCollisionEnter2D(Collision2D collision)
    {
        if(collision.gameObject.name == "Player")
        {
            Debug.Log("Player Stepped on platform");
            collision.collider.transform.SetParent(transform);
        }
    }
    private void OnCollisionExit2D(Collision2D collision)
    {
        if(collision.gameObject.name == "Player")
        {
            Debug.Log("Player has stepped off the platform");
            collision.collider.transform.SetParent(null);
        }
    }```

[sweet swan]

code looks functional, what's happening instead?

[still tendon]

What it's doing is, making the player a child of the moving platform however but the player's transform doesn't move along the paltforms transform

[sweet swan]

oh it's probably because your player has a dynamic rigidbody

those arent affected by parent translations

[still tendon]

Ohh

That makes sense

[sweet swan]

i don't spend that much time on platformers myself so i'm not sure if there's a better solution, but i'm sure you can find one if you google around

worst comes to worst you can always translate the player manually inside fixedupdate and track when the player is on with enter and exit

[still tendon]

If both of the rigid bodies are dynamic would that work?

[sweet swan]

nah

any gameobject with a dynam rigidbody will ignore changes to the parent transform

• for 2d anyways

[still tendon]

Got it to work

private void Update()
    {
        PlatformMove();

        if(moveright)
            transform.position = new Vector2(transform.position.x + PlatformSpeed * Time.deltaTime, transform.position.y);
        else
            transform.position = new Vector2(transform.position.x - PlatformSpeed * Time.deltaTime, transform.position.y);
    }
    private void PlatformMove()
    {
        if(transform.position.x > 97)
        {
            moveright = false;
        }
        if(transform.position.x < 87)
        {
            moveright = true;
        }
    }```

Removed the rigidbody from platform and now using this to move it

Object with dynamic bodies can be attached

here's a few videos/playlists about making a pong clone in unity

[glass coral]

I found a weird way to do it. It's perfect when scripting but crappy for prefabs, will look at your propsotiion

[mossy coyote]

anyone have any good methods for creating a 2d effect of a player throwing an object (like a grenade or something) for a top down game? To give the appearance of the object being thrown in an arc between two points, with shadow effect?

[glass coral]

use movement equation ? scale with height

[peak stirrup]

does anyone know any good tutorials on 2d biome generation?

[deft pumice]

So my 2d raycast works, however when its really close to a collider it will hit the collider
even when the collider is not in the raycast direction

[pseudo flame]

making a 2d gam and dont know how to code at all

pls help

[abstract olive]

Nobody is going to make your your game for you, if that's what you're asking. 🤔

[pseudo flame]

i wanna learn code

[hollow crown]

There are resources pinned to #💻┃code-beginner

[narrow gulch]

can i create a 3d video animation and put it in my 2d game as if it were a cutscene? (I don't want to do the animation on the unity itself, since I can't create a 3d animation in a 2d game)

[raven narwhal]

Hello! someone will send me a procedural generation tutorial?

[gloomy lagoon]

so yesterday i asked here for help and the code didnt gave any errors after that. But it still wont work. Please help meh

[mental totem]

Coroutines must be started with StartCoroutine method

[gloomy lagoon]

I never did that before can you give me a quick example? Only if you have time and want to

[mental totem]

StartCoroutine(LoadLevel(1));

[gloomy lagoon]

Ohh

thanku

Yess it worked. I got one other question. For my start menu or any other button in the game i made a script that loads a scene from a string i can edit in the editor. I implemented the scenes and wanted to switch them with the button. If i do that i get this error.

nvmd i fixed it my bad

btw you guys rock you help better than any tutorial ever could and i am super thankful to be here 🙏

[narrow gulch]

guys help me

[sweet swan]

there's nothing inherently 2d about a 2d project template, so if you create a scene with a perspective camera and make it into a cutscene with timeline or the like, i don't see why not

keep in mind that 2d physics can't interact with 3d physics, and 3d is a lot harder because youll need to juggle meshes materials and lighting as well

[narrow gulch]

yes, but the 3d animation would be basically a video (as if it were a yt video) and put it at certain times. I don't know if I made myself understood

[sweet swan]

if the 3d animation is all in the same scene, you can transition between the scenes as often as you like, and look into Timeline for making cutscenes

if it's similar to a yt video, you can skip all the messing about with 3d and just use this https://docs.unity3d.com/ScriptReference/Video.VideoPlayer.html

[idle wing]

Can someone help me with this error

[willow heath]

um did you put [system.serializable] before the class?

[cedar quarry]

Raycast2D hit;

This variable is never initaliazed, thats the cause of your unassigned local variable problem, you need an access modifier such as public at the beginning:

public Raycast2D hit;

Also, I'd recommend changing your if statement to be a bit more efficient (it doesn't make it much more efficient, but any efficiency is good)
Use hit.collider.CompareTag("PlayerShip") like:

if (hit.collider.CompareTag("PlayerShip"))
{
  //do
}

[blissful gale]

im wondering if there is a way to store variables on specific tiles on a grid. For example if a tile is tilled or not, and be able to edit what tile is in that spot.

[cedar quarry]

you could create a tile class

[blissful gale]

so make a custom grid?

[cedar quarry]

hmm

not sure about this actually

[blissful gale]

ive been looking online for days and havent found anything on it surprisingly

im new to unity so im not that experienced

my last resort was just placing down each individual tile as a sprite, which would be a pain

[cedar quarry]

class Tile
{
private:
  Vector2 pos;
  bool isTilled;
public:
  void Till()
  {
    //do stuff
    isTilled = true;
  }
}

this is just a very basic beginning of a class

but you could maybe build something off of this

id recommend looking into classes/structs in c#

theyre very useful

[blissful gale]

This is awesome, but where can I reference a specific tile?

[cedar quarry]

oh

are your tiles manually placed in the game?

through the editor

[blissful gale]

in a tilemap

[cedar quarry]

yep

[blissful gale]

The tiles are not placed in game

just changed

hopefully

lol

[cedar quarry]

huh

well uh

unfortunately i have little experience in unity 2d

is the tilemap an object in the inspector?

like

a gameobject

[blissful gale]

yeah its a child of a grid

which is a gameobject

[cedar quarry]

alright

hmm

yeah uhh

unfortunately

im not sure

[blissful gale]

all good, im sure ill find it eventually, thanks for the help

[sleek thistle]

how would i go about controlling the world light source with a boolean?

like cause it to go pitch black and you need a light to see anything

[sweet swan]

fastest solution that comes to mind is parenting a black rectangle sprite to the camera that covers everything, and setting it to render outside of sprite masks

then light sources just need to be sprite masks and youve got a rudimentary flashlight system

[sleek thistle]

huh alright

thanks

[sweet swan]

🍀

this is all assuming you aren't using the actual 2d lighting package

[sleek thistle]

i have no idea what that is

i'm completely new pretty much

[sweet swan]

yeah, i'd say it's better to start off with black squares and masks

you can always upgrade later!

[wooden gust]

anyone know of good tutorial for 2d in unity?

[dense flame]

Search for platformer tutorials

[wooden gust]

Does it make any difference for top down? and thank you

[tropic charm]

Try this tutorial if you are interested in top down. https://learn.unity.com/project/ruby-s-2d-rpg

[wooden gust]

Thank you!

[tropic charm]

I don't know for sure but it seems like that would be one of the use-cases for scriptable tiles.

[elfin sandal]

If I want to make a physics explosion at a certain point in the world what method do I use?

where all physics2d objects get moved away from the point

do I do a circlecast and then add an explosion force to all rigidbodies?

[valid schooner]

hey, I'm creating a simple 2D top down prototype game and wanted to create some physic based objects with item icon. Is there any disadvantage of using world space canvases per item over sprite renderer? I just fell more in control over UI than sprite renderer 😅

[nocturne cipher]

Hi, I'm a bit confused about whether this where to to go for help with 2d coding errors, but can anyone point me in the right direction for this:

I'm getting a CS1001 error on this code

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

public class PizzaSpawner : MonoBehaviour

[SerializeField]
private GameObject[] pizzas;

private BoxCollider2D col;

    col = getComponent<BoxCollider2D> ();

    x1 = transform.position.x - col.bounds.size.x / 2f;
    x2 = transform.position.x + col.bounds.size.x / 2f;
}

void Start()

IEnumerator SpawnPizza(float, time) {
    yield return new WaitForSecondsRealTime(time);

    Vector3 temp = transform.position;
    temp.x = Random.Range (x1, x2);

    Instantiate (pizzas[Random.Range(0, pizzas.Length)], temp, Quaternion.identity);

    StartCoroutine (SpawnPizza(Random.Range(1f, 2f)));

Won't compile until I figure out what's wrong 😑

[elfin sandal]

can u post more about what the error says

[nocturne cipher]

Yes, happy to. One sec

Assets/PizzaSwap/Scripts/PizzaSpawner.cs(28,33): error CS1001: Identifier expected

[elfin sandal]

IEnumerator SpawnPizza(float, time) {

[forest wagon]

hey, I have a question. in my game, I have 2 "modes" for the UI. it's a 2d game where one mode displays only text on the screen, while another mode displays that same text to the side with other info on the left. how do I go about implementing that? (I want to be able to toggle the mode via code)

[nocturne cipher]

Awesome, that worked!! ...But now I have a new error 😅

Assets/PizzaSwap/Scripts/PizzaSpawner.cs(17,15): error CS0103: The name 'getComponent' does not exist in the current context

[elfin sandal]

capitalize it

[nocturne cipher]

Amazing. That worked too. Thank you

Now it's: Assets/PizzaSwap/Scripts/PizzaSpawner.cs(29,26): error CS0246: The type or namespace name 'WaitForSecondsRealTime' could not be found (are you missing a using directive or an assembly reference?)

Looking that up

[tropic charm]

Ran across this in Unity's github repository. I don't see a way to create the per-tile information at design-time but this class will allow you to do it at runtime.

https://github.com/Unity-Technologies/2d-extras/blob/master/Runtime/GridInformation/GridInformation.cs

[strong heron]

Do you define time somewhere?

[nocturne cipher]

Solved it

[strong heron]

Oh wait I see

[nocturne cipher]

Realtime

Instead of RealTime

😂😭

[strong heron]

You might be looking for overlap ircleall

[forest wagon]

anyone?

[strong heron]

Sorry, OverlapCircleAll

[elfin sandal]

is there an add explosion force for 2d rigidbodies

I know there is one for 3D

https://docs.unity3d.com/ScriptReference/Rigidbody.AddExplosionForce.html

[strong heron]

If you want it to add force away from a point use transform.InverseTransformPoint

[elfin sandal]

which point

[strong heron]

That’s a 3D function

[elfin sandal]

yah is there a 2d one

[strong heron]

Ah, maybe that’s better then

[elfin sandal]

does it work in 2d

[strong heron]

It doesn’t look like there is a 2d function

OverlapCircleHit.rigibdody2D.AddForce(Explosion.transform.InverseTransformDirection(OverlapCircleHit.transform)

Is one way to write it I believe

Although you’d probably want to normalize it and possibly add more force dependent on distance but depends on desired function @elfin sandal

[elfin sandal]

ok thanks

[orchid pewter]

should i change the collider box dimensions for each different animation type for the player?

the sprite changes shapes so the box collider should also change?

not per animation frame but per animation cycle?

[still tendon]

Well, to start with, I have a spawner that spawns my objects (meteorites and coins) from right to left between the values of the size of my map, i.e.: minY = -1.13 and maxY = 1.13. With the current script, I get a spawner like this :

You can see that on the red line, I have a row of meteorites that is too similar, but I want something a little more random, like this for example (it's a diagram):

The code : https://paste.myst.rs/ybwkxwjg

[brisk badge]

I've been trying to set a health bar system up for my enemies using this script: https://pastebin.com/5KU4Bmvn

However, when I run the game, even when the enemy's health is 4 (maxHealth = 10), newScale (health/maxHealth) equals zero. How can I fix this issue?

[dull badge]

@still tendon I've seen you ask this and get answers 2 or 3 times already. Nobody is going to code it for you.

[idle wing]

How do i make something move up relative to a parent?

The lasers fly up in the world, i want them to fly out the front of the ship

[still tendon]

answers? no, just suggestions, but they didn't lead to anything, I have already tried

[tropic charm]

Because health and maxHealth are both integers any math you do with these variables will done as integer math. You can force the compiler to do it as 'float math' by casting one of the variables to a float. For example: (float)health / maxHealth.

[rough gorge]

How can i revert animations to another spriteRenderer than actual one?

[tropic charm]

You might need to elaborate. Are you wanting to swap sprites?

[craggy kiln]

This is a double post, he figured it out in general a short bit ago.

[lofty cosmos]

Set their rotation and then use transform.Translate() with the Space.self parameter maybe?

[slate wyvern]

hello, when using rigid body i want my falling objects to move at a set speed and not accumulate speed according to gravity, is there a setting to do that? or do i need to write a script for it

[hollow crown]

wow I really wish I could help but instead you decided to get muted for being a troll - good luck with that.

[snow willow]

2d or 3d?

If it's 2D you can set the gravityScale to 0 on an individual object

If it's 3D there's a Use Gravity checkbox you can turn off

[nocturne cipher]

Can anyone point me to a simple way to make a 2d item disappear after X time of not colliding with a player-character?

[still tendon]

how do i set jump height to start jump height
and not to a number

[fallen flicker]

Under the start function or wherever you want just put jumpHeight = startJumpHeight

You'd have to make startJumpHeight a variable tho

[still tendon]

ok thanks

[chrome parcel]

how do i duplicate a game object to the hierarchy?

[craggy kiln]

ctrl + d is the default shortcut

You can also copy - paste

[chrome parcel]

i mean with code

[craggy kiln]

Get a reference to the object, and it can be as simple as GameObject.Instantiate(originalGameObject);

[warped zealot]

So quick question

Say I am storing a path to a sprite in my Resources Folder

This sprite happens to be part of an atlas

How would I load a specific sprite from an atlas using Resources.Load?

SpriteAtlas.GetSpriteis what I'm looking for

[rotund remnant]

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

[burnt badge]

im trying to get an image to display what an orthographic camera is capturing, but my mesh renderer is showing up in the scene view, but not the game view?

[white bronze]

anyone know how i can launch my player the oppisote way when i shoot? I think its like a lot of recoil or something. i tried using this but it only launches me 1 direction. it doesnt launch the other way
i tried using this ```using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Weapon : MonoBehaviour
{

public float offset;

public GameObject projectile;
public ParticleSystem shootEffect;
public Transform shotPoint;

public Rigidbody2D rb;




private float timeBtwShots;
public float startTimeBtwShots;

private void Update()
{
    // Handles the weapon rotation
    Vector3 difference = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
    float rotZ = Mathf.Atan2(difference.y, difference.x) * Mathf.Rad2Deg;
    transform.rotation = Quaternion.Euler(0f, 0f, rotZ + offset);

    if (timeBtwShots <= 0)
    {
        if (Input.GetMouseButton(0))
        {
            shootEffect.Play();
            
            Instantiate(projectile, shotPoint.position, transform.rotation);
            timeBtwShots = startTimeBtwShots;

            rb.AddForce(new Vector3(rotZ, -rotZ, 0f) * 5f) ;
        }
    }
    else
    {
        timeBtwShots -= Time.deltaTime;
    }


}

}```

[tropic charm]

You have already calculated the (non-normalized) vector (difference) that points to where you are shooting so you can use the negative of that to determine the direction of the force. Something like this:

    Vector3 forceVector = -difference.normalized;
    rb.AddForce(forceVector * shotForce);

You will likely need to use a different value for your force.

[white bronze]

oh ok

i will definetly try thanks

[tropic charm]

Sure.

[nocturne cipher]

Hi, I have a game object spawner that spawns items (pizza in this case) over a random range of time and removes the object when a player-character collides with it. I want to also have any pizza a player-character doesn't collide with fade out over a random range of time and be removed. I am assuming there is a much cleaner way to do this than what I am poking around trying to figure out:

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

public class PizzaSpawner : MonoBehaviour
{
[SerializeField]
private GameObject[] pizzas;

private BoxCollider2D col;

float x1, x2;

// Start is called before the first frame update
void Awake()
{
    col = GetComponent<BoxCollider2D> ();

    x1 = transform.position.x - col.bounds.size.x / 2f;
    x2 = transform.position.x + col.bounds.size.x / 2f;
}

void Start()
{
 StartCoroutine (SpawnPizza(1));   
}

IEnumerator SpawnPizza(float time) {
    yield return new WaitForSecondsRealtime(time);

    Vector3 temp = transform.position;
    temp.x = Random.Range (x1, x2);

    Instantiate (pizzas[Random.Range(0, pizzas.Length)], temp, Quaternion.identity);

    StartCoroutine (SpawnPizza(Random.Range(0.01f, 0.1f)));
}

} // class`

Hmm, I think I hit the spam filter limit, because I can't post the second script...

[tropic charm]

What I've done--and it seems dodgy but works--is just immediately call Destroy() and give a delay. This works even if the game object gets destroyed elsewhere before the delay.

    GameObject projectile = createProjectile(fromTheLeft);
    Destroy(projectile, 3.0f); // 3 seconds maximum lifetime.

[nocturne cipher]

Oh that's great

I don't mind dodgy at all in this case. Just trying to get it to work

Hmm, now I'm getting a float to int error (CS0266):

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

public class PizzaSpawner : MonoBehaviour
{
[SerializeField]
private GameObject[] pizzas;

private BoxCollider2D col;

float x1, x2;

// Start is called before the first frame update
void Awake()
{
    col = GetComponent<BoxCollider2D> ();

    x1 = transform.position.x - col.bounds.size.x / 2f;
    x2 = transform.position.x + col.bounds.size.x / 2f;
}

void Start()
{
 StartCoroutine (SpawnPizza(1));   
}

IEnumerator SpawnPizza(float time) {
    yield return new WaitForSecondsRealtime(time);

    Vector3 temp = transform.position;
    temp.x = Random.Range (x1, x2);

    Instantiate (pizzas[Random.Range(0, pizzas.Length)], temp, Quaternion.identity);

    StartCoroutine (SpawnPizza(Random.Range(0.01f, 0.1f)));
    
    Destroy (pizzas[Random.Range(3f, 13f)]);
}

} // class`

[white bronze]

hey, i finally got around to trying it and it didnt work

[tropic charm]

Did you make the force a larger value? Or is the direction incorrect?

[tropic charm]

I think you want to do something like this:

  GameObject pizza = Instantiate (pizzas[Random.Range(0, pizzas.Length)], temp, Quaternion.identity);
  Destroy(pizza, Random.Range(3f, 13f));

[nocturne cipher]

Unfortunately it's giving me this error now:

Destroying assets is not permitted to avoid data loss.
If you really want to remove an asset use DestroyImmediate (theObject, true);

Oh, I had an idea... what if instead of doing this I simply applied the same thing that is happening when a player collides with the pizza to when the pizza collides with the floor or other pizzas, but with a delay?

[tropic charm]

I played around with your script with my suggested changes and it seems to work.

[tropic charm]

I did find a problem. The difference vector's Z component wasn't getting zeroed-out so here's what I wound up doing...

Vector3 forceVector = -difference;
forceVector.z = 0f;
forceVector.Normalize();

rb.AddForce(forceVector * shotForce);

[nocturne cipher]

Ok, progress, all I needed was to learn about the wonderful world of object pooling

[burnt badge]

im getting an issue where my mesh renderer shows up in the editor, but not in the game tab

left shows editor vier, right shows ingame

[azure dew]

can someone help me

https://hatebin.com/bjetweljbc

the text isnt changing

after collision

guys

pls

[sonic herald]

try if (col.gameObject.tag == "yourtag")

[azure dew]

i've done this

but

its all good

its says in the console

that it touched

but the text didnt change

and can u help me pls

[sweet swan]

swap it for an image or raw image component

other renderers behave unpredictably when used with rect transforms

alternatively keep the mesh renderer, but move it to a gameobject with a regular transform

[white bronze]

sorry for not responding. Yes I tried increasing the shotForce but it didnt work. I will try this code though.

[white bronze]

thx for the help. THis code works!

[tropic charm]

Awesome! Glad to help.

[burnt badge]

i turned its rect tranform into a regular tranform and it still does not appear ingame

I tried turning the mesh renderer into an image component, and now it shows up as a black square, even though in the editor, it shows the texture renderer just fine

[sweet swan]

busy rn, hopefully someone else can take over

[bright dome]

you can make a circle collider and add any enemy OnTriggerEnter2D to your targets then remove when OnTriggerExit2D

or other way, use Physics2D.OverlapCircle every interval time (1 sec maybe) to get all enemies in range

[forest hedge]

https://gyazo.com/b481660b20dc38752d35933e426785f7

so i'm running into this problem where the player is "jumping" after going up the ramp, and I know the source of this problem ```cs
rb.velocity = new Vector2(movement.x * speed * Time.deltaTime, rb.velocity.y);

but if I change the rb.velocity.y to 0 or multiply it by Time.deltaTime it slows down heavily

[forest steeple]

how can i make looping background in 2d on menu
i have only 1 photo
no layers only 1 photo

[forest hedge]

https://www.youtube.com/watch?v=zit45k6CUMk

[forest steeple]

i had only 1 photo

i dont have layers

[forest hedge]

I don't know then tbh

I don't know if you can do it

[white bronze]

then u can just amp up the movement speed

[forest hedge]

what?

[white bronze]

if u move slower then u can just make the speed a lot higher

[remote moth]

Why is this every time false?

float extraY = 0;
RaycastHit2D blocks = Physics2D.Raycast(collider.bounds.center, Vector2.down, collider.bounds.extents.y + extraY, LayerMask.NameToLayer("Block"));
RaycastHit2D items = Physics2D.Raycast(collider.bounds.center, Vector2.down, collider.bounds.extents.y + extraY, LayerMask.NameToLayer("Item"));


return blocks.collider != null || items.collider != null;

there has the correct Layermask.

[snow willow]

Name to layer is wrong

https://docs.unity3d.com/ScriptReference/LayerMask.GetMask.html

[remote moth]

no, i think not

[snow willow]

I think so

Name to layer gives the layer index

[remote moth]

wait, i try

[snow willow]

E.g 8 for layer 8. LayerMask is a bitmask

[remote moth]

oh, ok that i doesn't know

[snow willow]

You should really just use a serialized LayerMask field

And set the mask up in the edit

Editor

[still tendon]

Is there any way to animate several sprite pieces with a single animator?

It's a base sprite with modular pieces (eyes, hair, etc) and they would all follow the base animation just with their own sprite sheets

[still tendon]

@tropic charm You can help me pls, if is possible 😦

[tropic charm]

Is it regarding the issue you posted above? #🖼️┃2d-tools message

[still tendon]

Yes, that's right

[tropic charm]

I didn't look too close at your code but my suggestion for tackling a problem like that is to not bother trying to get true randomization. You might approach it more from the standpoint of (conceptually) a grid with margins. You have a one-to-one relationship of a grid cell to an object that will occupy the space of the cell. This way you just put the objects in a random spot of each of the cells. You use the margins to ensure that the object can't possibly overlap anything in a adjacent cell. You can stagger the x-offsets of alternating rows to avoid having an area where objects wouldn't otherwise occupy.

[hollow agate]

So as you see, the bullets of the aliens rebounds on the other aliens and so I am not sure how to toggle that off or how to code it. My aliens are generated at the start of the game using an array of GameObject. Thanks

[still tendon]

It all sounds complicated to set up, but I can't just change something in the current code to hope for a similar result of what I want to have?

[tropic charm]

There might be something but I don't understand your code well enough to make any suggestions regarding it.

[still tendon]

good deal too bad

[crystal geode]

I'm having an issue where code that triggers on GetKeyDown triggers twice on a single button press. Would anyone know what could cause this?

ah, I think I figured it out, it seems to be some sort of issue with FixedUpdate as opposed to Update

in that case, followup question

if I'm using Application.targetFrameRate = 60; in my Start(), will Update() run once per frame, 60 times per second?

[radiant cedar]

I'm looking online to check what people consider the best movement script "type" to work with, and mostly what I can find is a raycast character controller from around 2015.
Is that still applicable together? or is there now a better way?

[snow willow]

Update always runs once per frame, no matter what the current framerate is. Application.targetFrameRate means your game will be limited to 60FPS (to the best of its ability), but it is still possible for the framerate to be lower than that.

[mellow owl]

hi guys, im having a problem with Camera.ScreenToWorldPoint, it work perfectly fine when the camera is at y=0 but once I move the camera up it starts to behave weirdly

[tropic charm]

There's a known issue regarding the Z-pos. Here's what I do, which seems to work:

Vector3 currentMousePos = Input.mousePosition;
currentMousePos.z = Camera.main.nearClipPlane;

Vector3 mouseWorldPos = Camera.main.ScreenToWorldPoint(currentMousePos);

[mellow owl]

I did exactly that

but it wont work

I even went to page 2 on google search

[tropic charm]

Here's the article I based that on. https://gamedevbeginner.com/how-to-convert-the-mouse-position-to-world-space-in-unity-2d-3d/

I keep my camera at -10 and it seems to work.

This is with 2109.4.x LTS.

[mellow owl]

yeah I read this, im actually haven't updated to the LTS version

[tropic charm]

Is your camera isometric? Or whatever it called?

[mellow owl]

orthographic

i tried perspective

same issue

[tropic charm]

Are you using ScreenToWorldPoint() for the mouse cursor or something else?

[mellow owl]

yes

[tropic charm]

So basically doing the same as me. I don't know what the problem would be then.

[mellow owl]

okay, thanks anyway!

[tropic charm]

You might play around with this script and see if it works.

using UnityEngine;

public class MouseToWorld : MonoBehaviour
{
    private Vector3 _mouseWorldPos = Vector3.zero;

[mellow owl]

okay, thanks a lot

[tropic charm]

I notice that the Z pos is non-zero. So watch out for that. You might have to zero-out the Z before doing any further processing with the result.

[mellow owl]

huh so I just noticed that when I move the camera up to y=8, the line is directly inverted

[tropic charm]

You're not using any weird camera settings are you? Here's what I have:

[mellow owl]

same thing

[tropic charm]

Did that script return valid values?

[mellow owl]

I haven't implemented it yet, gimme a sec

[tropic charm]

I see you set the Depth to -10. You didn't do that intending to set its Z position at -10 did you?

You can just attach that script to an empty game object at the root of the scene hierarchy, btw.

[mellow owl]

huh

your script

actually

return proper coords

[tropic charm]

Hmm. I guess that's good.

What the difference between it and yours is the question.

[mellow owl]

yeah im diggin it

thank you so much

[tropic charm]

Yep. You'll figure it out.

[mellow owl]

ok

so

the problem is instead of using Camera.main.ScreenToWorldPoint

I attach the camera to the script and use it

I thought it would be some stupid error that makes me hate myself but I dont understand why did that make a different

is it because my camera is a prefab?

@tropic charm thank you so so much

[tropic charm]

No problem. Glad to help.

[hearty chasm]

Hi, I need help with spawning sprites continuously. I am making a rhythm game and after a certain amount of beats, the prefabs stop spawning correctly (being rendered with no sprite). Here's a link to the code (but I've never used hatebin before so Im not sure if it works lol) https://hatebin.com/ynppiqiybc

[desert swallow]

@hearty chasm how many spawn before it breaks? The code you've shown looks fine so far

[remote moth]

how can i create a text object wihtout canvas?

[radiant cedar]

I'm looking online to check what people consider the best movement script "type" to work with, and mostly what I can find is a raycast character controller from around 2015.
Is that still applicable together? or is there now a better way?

[desert swallow]

Why don't you want a canvas?

[remote moth]

but i like do create as a object that are one a postion how other objects

and not still one the same position of the screen

[desert swallow]

World position canvas is what you're looking for

[remote moth]

yes, i think

[hearty anvil]

Hi, I was trying to make a frame rate display and I just want to double check it's right.
This is the code I've used for it. It works but it gives me very high numbers, falling as low as about 2000 fps when there's a few hundred bullets on screen. Is this calculating it correctly? Anything I should change?

[desert swallow]

@hearty anvil you've overcomplicated it. 1.0f / Time.deltaTime is enough to give you the FPS

Unless you specifically want it to only update every 0.5s

[hearty anvil]

I thought that it might be really finicky and messy if it was updating so fast you couldn't read it

And that the average fps for a set amount of time may be more reliable than the fps of a single frame

[desert swallow]

finalTotal = frameTotal / frameRefresh you're setting the (final total to the frame rate at each frame for 0.5s)/ 0.5

that doesn't look right

assuming you get 60 fps, you're adding 60 to frameTotal each frame, which in this example would be 60*30 = 1800 / 0.5 = 3600

to get the average, you'd want to divide by the number of frames that have passed in frameRefresh amount of time

so instead of adding the frameRate to frameTotal, you can just add 1 each frame

void Update()
{
  frameCounter += Time.deltaTime;
  frameTotal++;
  if(frameCounter >= frameRefresh)
  {
    finalTotal = frameTotal / frameRefresh;
    frameTMP.text = "FPS : " + finalTotal;
    frameCounter = 0;
  }
}

[hearty anvil]

I see

Yep this seems to work

Appears my fps is actually around 200

Wait no I retried it and the fps was around 2000

Nvm again I reset frameTotal to 0

Oh dear my game is struggling a bit

Barely able to keep above 60fps

Well thanks for the help

[desert swallow]

No problem

Are you making a bullethell?

[hearty anvil]

Yeah

Although now I'm a little concerned

I haven't added everything I want to yet and it looks like FPS drops below 60 at around 600 bullets on screen

Maybe I'm giving the bullets themselves too much to do

[desert swallow]

Are you pooling the bullets?

Or are you just instantiating and destroying them?

[hearty anvil]

I haven't heard much about pooling so probably not

I'm instantiating and destroying them

[desert swallow]

pooling is keeping a bunch of instances in memory and instead of instantiating/destroying you loop through the list and use the oldest one

It's good if your bullets are similar

Unity actually have their own tutorial on it: https://learn.unity.com/tutorial/introduction-to-object-pooling

[hearty anvil]

Ahh thank you

How much does it help exactly

Would you be able to have say over a thousand bullets that all act similarly and simply without dropping frames?

[violet ember]

i need help on zooming out when entering a room

[desert swallow]

It'll definitely be better than not using it

You'd have to do some tests on your own project to see how well it improves it, however your FPS counter should be a good metric to begin with

[desert swallow]

Can you be more specific?

[hearty anvil]

Yeah I decided I was gonna need a FPS counter as soon as to see what does and doesn't help with optimising

[violet ember]

okay so i have a room for a boss like fight and i would like the camera to zoom out so that it captures more of the scene

and idk how to do it

[desert swallow]

https://docs.unity3d.com/ScriptReference/Camera-orthographicSize.html

@violet ember Increasing the orthographic size will effectively zoom the camera out

[violet ember]

but i would like the camera to only zoom out in a specific place

and I'm also using cinemachine for my camera

[desert swallow]

https://www.youtube.com/watch?v=2jTY11Am0Ig

I haven't used cinemachine, but that tutorial might cover what you're looking for

[radiant cedar]

I'm doing this:
Debug.DrawRay(transform.position, Vector2.up * -20, Color.red);
On my player but I can't see anything. Any tips?

[desert swallow]

You won't see it in the game view, have you looked in the scene view while playing?

[radiant cedar]

yup

Just tried to also use duration (5.0 for 5 seconds) and depthTest=false; still not seeing anything

[desert swallow]

Are you calling it in your Update?

Otherwise it'll only draw it for 1 frame

[radiant cedar]

yup

calling it in Update, but I used the time=5 just in case anyway

tried without it as well, still nothing

[desert swallow]

There's a Gizmos button at the top right of the scene view, make sure that's enabled

[radiant cedar]

oh yeah that was it. Thanks!

[desert swallow]

🥳

[radiant cedar]

I saw that actually, just used the dropdown; didn't think it was actually a button :p

[desert swallow]

Yeah it's a toggle all

[orchid pewter]

is it possible to find the height of a sprite in pixels?

or as a float?

[desert swallow]

Renderer.bounds.size.y

Will give you it in in-game units

@orchid pewter

[orchid pewter]

thank you

[hearty anvil]

@desert swallow When you pool objects are you supposed to do it as soon as you run your game or as soon as the scene that needs them is active? If it's the former, how do you prevent the inactive objects from being erased when a new scene loads?

[desert swallow]

Hold off on creating the objects until you need them, that way you're not using memory for no reason

Look into DontDestroyOnLoad if you want to do it that way

Otherwise you could have separate pools in each scene

[hearty anvil]

So would it be the latter then?

[desert swallow]

I would go for the latter personally

[hearty anvil]

Alright

Makes sense

[shell wadi]

https://pastebin.com/NpwgFu78 I need help, my character doesn't jump correctly

When I set grounded to false, it cant jump, and loops the jump animation

When I set it to true, it can walk normally but doesn't do the jump animation and jumps infinitely

[desert swallow]

I answered this in #archived-code-general

You never set grounded to true when it touches the ground, and you don't set it to false when they jump

[rose prawn]

i have this script to move an objcet along the y axis, if i apply this to more than object, they ALL will move at once

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

how do i change this to only apply to the current object being clicked

[desert swallow]

@rose prawn look into the OnMouseDown() function

[still tendon]

hello
i change my code
in script
and when it changes, it dissapears

[desert swallow]

you probably just need to open the file again

[still tendon]

what file

ok so im getting ignored

thats fine

[desert swallow]

@still tendon
the file
that disappeared
the file that disappeared
the file you're talking about that disappeared
the disappearing file

[still tendon]

oh

sorry

i meant
