@thick geyser Do the things you are trying to hit have actual colliders?
ruby karma
can use Debug.DrawRay/Line to visualize the raycast
always do ^ when raycasts aren't working as intended
thick geyser
oh ok, do i just copy the raycast part into that?
ruby karma
look up the documentation on how those work (: Similar to raycast overloads, but not exactly the same
plush coyote
do this line below your raycast
Debug.DrawLine(transform.position, transform.position + new Vector2(anim.GetFloat("horizontalMoveLast"), anim.GetFloat("verticalMoveLast")), Color.red);
I see, let me try that
plush coyote
Just to see if it is the right direction
im assuming interactableDistance is not 0?
plush coyote
A better way of doing it would be
Vector2 dirOffset = new Vector2(anim.GetFloat("horizontalMoveLast"), anim.GetFloat("verticalMoveLast")) * interactableDistance;
Debug.DrawLine(transform.position, transform.position + dirOffset, Color.red);
.normalized
plush coyote
His raycast isn't normalized
so this would be more accurate
Unless the raycast auto normalizes
ruby karma
nah it doesn't
plush coyote
not actually sure about that
thick geyser
oop need to change the vector 2 to a vector 3
plush coyote
just cast the transform.position to a vector2
plush coyote
(Vector2)transform.position
thick geyser
that doesnt work
plush coyote
be more specific
thick geyser
it cannot be used like a method
plush coyote
you have a typo somewhere
ruby karma
post code
thick geyser
plush coyote
read what I sent again
ruby karma
new Vector2
ruby karma
and wrong encapsulation
ruby karma
try to think why you are writing something before actually typing it. () basically encloses the values inside it into a single expression. so everything inside () is a single value
ruby karma
Unity dropped the native support for that
I remember reading somewhere you gotta do that on your own, they have an example somewhere
pulsar barn
so we cant do that anymore?
thick geyser
there is no ray being drawn, hmm
thick geyser
yeah
plush coyote
then are you sure interactableDistance isn't 0
plush coyote
try increasing it
thick geyser
alright
plush coyote
to like 5
ruby karma
hundred
plush coyote
what is the radius of your character?
because anything under the radius as the distance value makes no sense
thick geyser
what do you mean by radius? the size of the sprite?
plush coyote
if your player collider has a .5f radius or something
then .2f as the interact distance will never exit your player collider
thick geyser
oh I see whats happening, it is too small
ruby karma
^ the maxDistance is from the centre of the player position.
plush coyote
it needs to be at least larger than the radius of your player
thick geyser
I guess i may have to make it scale for the up facing then
my game is a top down rpg, for context
ruby karma
that isn't context
plush coyote
that's what I thought, why would it need to scale up though?
thick geyser
oh wait, the ray is coming out of the head and not the collider at the feet
ruby karma
screenshots ๐คทโโ๏ธ
pulsar barn
i mean is screen configuration like this
thick geyser
thick geyser
oh alright
plush coyote
I forget exactly what it is called, but there is some property in there to get the offset
@pulsar barn Yeah, dont think that exists anymore in newer versions
you have to make an options menu instead
abstract mural
Yeah you need to make your own in the settings of your game
pulsar barn
i hope unity creator make setting like that again
thick geyser
hmm, I disabled the button input for testing.
the line is touching, but it isnt detecting
I may just be an idiot and missed something obvious though
@plush coyote
eternal hamlet
It might be detecting your players collider
You can use a layer mask to only detect the other object, or get an array of all collisions and loop through them
thick geyser
ok, I tried doing if (interactable.collider != playerObject.GetComponent<Collider2D>())
but that didnt work
ill try the layer mask then
plush coyote
the second parameter of the raycast is not your destination of the cast
it is just a direction
eternal hamlet
You can put in some more debugs to see if it's detecting any collisions
plush coyote
@thick geyser You should pass in a direction as the second parameter
thick geyser
oh yup that makes sense
plush coyote
if you want to be consistent, change your dirOffset line to this
Vector2 rayDir = new Vector2(anim.GetFloat("horizontalMoveLast"), anim.GetFloat("verticalMoveLast")).normalized;
and pass rayDir in as the second parameter of the raycast
then, add back your interactableDistance as the third parameter
plush coyote
for the debug line, change it from using just the transform.position + rayDir to transform.position + (rayDir * interactableDistance)
thick geyser
already did that while you were typing lol
plush coyote
remember to normalize it
thick geyser
where do I normalize?
plush coyote
if you want to be consistent, change your dirOffset line to this
Vector2 dirOffset = new Vector2(anim.GetFloat("horizontalMoveLast"), anim.GetFloat("verticalMoveLast")).normalized;
thick geyser
ok, there
now let me try this out
hmm, still nothing. I need to set up a layer mask I guess
plush coyote
Send your current code
thick geyser
plush coyote
but yeah, you should use raycasts regardless
how about you debug.log in the outer if statement
to see if it hit anything
plush coyote
So then your interactable doesn't have the tag you think it has
Either it has no tag, or one is misspelled
or it is hitting something else entirely
plush coyote
Then I would set up the layermask
thick geyser
in both places
ok
thank you for all your help btw!
I know ive probably been a pain lol
plush coyote
not really, a lot of people here just ask for free code and copy paste without understanding anything
you actually understand whats going on though, so its easier to help
thick geyser
yeah, I dont like doing that. I have been dealing with this problem for 2 days, trying to fix it myself. Thats what I really want is to understand it for later
ok, I just had to set the player's layer to Ignore Raycast
Its working now!
plush coyote
it would be better to pass in a layermask as a parameter of the raycast
and have the interactables on a specific interactable layer
then you don't even need a tag for them
because your raycast would only be able to hit interactables
thick geyser
thats true, then I could make NPCs also on that layer
yeah
Im also planning on putting trigger colliders in front of each object or on the side I want a specific interaction for. Does that make sense in conjunction with the raycast?
I want that so I can also put things in corners and not worry about overlapping
plush coyote
what do you mean in conjunction with
like, the raycast would hit the trigger?
or the trigger would work independently
thick geyser
the trigger would be independent
so I could have the player have a different response interacting with the back or side of something
plush coyote
I cant really say if it would be better or not because I don't know how everything in your project is set up
thick geyser
yeah that makes sense, ill just have to see as I go
plush coyote
but you can always just ask here again if you have a specific issue with it
thick geyser
yeah, thanks! you've really helped me, and I've learned some good things to make my code better too!
see you around then when I break something again haha

Hello there, currently I;m having a project that uses LWRP(I know, it's an old one), I am having some issue when introducing pixel perfect camera into the project
The game was designed at 960x540 on 16PPU
so I set up the project that way
However after I switch the screen resolution into 1080p, or 4K, even if I've checked the stretch fill
The rendered image remains un-scaled

Never mind, just found it, I have to use 2D Renderer in order to make that actually works

Unity 2D Collider, is there a version of OnTriggerExit but it triggers when only part of the collider is exiting
I need this cause I have a terrain (e.g. water) and I only want to make water sounds while the player is on top of it, this works when the player "enters", but when it exits, there's some delay because the player's collider is "bigger" and not a single dot, so that causes latency before the water walking sound changes back to the normal walking sound, if that makes sense
the only workaround is i have to create colliders surrounding the water as well, for the hard concrete floor
spring ledge
You could use OnTriggerStay and compare bounds yourself

tight shard
You could use OnTriggerStay and compare bounds yourself
@spring ledge its harder than i thought (to make the footstep sounds in/out of the 2D terrain sound nice/responsive). I think the next solution I thought of is to make a "tiny" collider 1x1 pixel wide, store it as a child gameobject of the player, and when the player is moving right, it'll move this collider to the right, if left, then left, if up, then up, if that makes sense.
ah i can use OnTriggerStay and the direction
i'll try ontriggerstay with direction into account

i mean it does, i just dont understand what it means

First question here.
Using boxcast for isGrounded, issue is that when jumping from under a platform I get grounded because of the collider, I've tried to make the boxcast smaller heightwise but to no avail.
Is it a good practice to make a empty child and have the boxcast on that instead?
Or should I disable the platforms as I am jumping (not falling) ?
Any tips would be great, ty
might be wrong channel, sorry if so
spring ledge
I've seen multiple tutorial use an empty gameobject to place the boxcast, don't see why you wouldn't. You could even just add some offset to your transform.position, but it's nicer to be able to place it in the editor
I wonder what the best way for a groundcheck is though. I've often seen the boxcast way, but it's kinda weird imo. You already have a physics engine which stops your object, so it feels like you should be able to use that
fresh bridge
Ok yeah, that is sort of what I want to be able to do, not fiddle with gizmo or debug.draw
spring ledge
Maybe can just set it on OnCollisionEnter or so
Would have to check orientation and such though, since else you'd still set ti to true if you hit your head on a platform instead of your feet
fresh bridge
I've tried so many approaches and always found issues I could not fix ๐ Boxcast is what I've been looking for, cept for the platform thing atm. :)
I will try the empty and if it fails I will fix with OnCollisionEnter, I have time ๐
Thanks for the input!
tropic inlet
tbh, I wish I could like
[SerializeField]
private GameObject groundCheck;
private void Start(){
groundCheck.GetComponent<Collider>().OnTriggerEnter += (col) => {
//code
}
}
setting the OnTriggerEnter of an object the script is not attached to
fresh bridge
That would've been ace
but there is a way to get another object is there not? ๐ค I am quite the noob at this so not sure
tropic inlet
u can get another object with, like GameObject.Find, or some RaycastHit but
i only know how to set the OnTriggerEnter/OnCollisionEnter of the object a script is currently attached to
spring ledge
OnTriggerEnter isn't a real even,t it's just a function called by Unity
fresh bridge
Ok yea
tropic inlet
I can prolly implement my own way of doing it

Hey I'm creating a Tower Defense game and now that I have a wave system with enemies prefabs I want to start placing towers. So for this I have to define where can the player place a tower/turret. I currently have a Grid that contains Tilemaps (Road, Decorations, Buildable terrain...)
Since this is a grid and I can actually see the cells in my Scene view would there be a way to do something with my BuildableTerrain Tilemap? Like getting every cells in this Tilemap or something?
spring ledge
I mean, you have errors. Check your code in the editor and see what's wrong. If you "don't understand any of it", you probably will have to learn C#
spring ledge
it says various things
tropic inlet
do i change it?
it's text
u just replace the text as u would in a word document
basically,
ok, but i want u to
click moveSpeed
then hold alt and press the down arrow key
once
if u are using Visual Studio
spring ledge
Teaching them fancy shortcuts
tropic inlet
that should move that line down
now save the file
and see if it works in Unity
I have a feeling "horizontal" is supposed to be "Horizontal"
that's what that axis is called by default
of course, it's possible for people to change input settings
cant watch streams rn
spring ledge
Well once you remove all the errors, it should work. Does it stil show errors?
You still ahve to move the moveSpeed line
tropic inlet
yea it needs to be under the {
then remember to press ctrl + S
to save ur file
that asterik at the upper left means ur file is unsaved
like anyone who doesn't follow my religion
buoyant bolt
You need to move line 6 down the "public float movespeed"
tropic inlet
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Move2d : MonoBehaviour
{
public float moveSpeed = 5f;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
Vector3 movement = new Vector3(Input.GetAxis("horizontal"), 0f, 0f);
transform.position += movement * Time.deltaTime * moveSpeed;
}
}
this should work
notice this:
{
public float moveSpeed = 5f;
Once you attach this to your object, and you press play
if your character does not move whenever you press your left and right arrow keys
you might need to change this line
Vector3 movement = new Vector3(Input.GetAxis("horizontal"), 0f, 0f);
to
Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), 0f, 0f);
Anyone knows how I could have a turret system for my Tower Defence game? I already have a Grid that contains Tilemaps (one for the road, one for the buildable area...) but the only thing I can get so far is all the cells position within a tilemap but it also takes the empty ones any idea if there's a way to check if a tilemap cell is "empty" or another way to do this?
@still tendon you defined your condition in the Jump method. You're calling Jump() every time and checking if you're jumping that's kinda weird.
You should rather put your condition
if (Input.GetButtonDown("Jump")
where you actually call Jump (in your Update() I guess) and call Jump() inside it.
Then define Jump() to do a single action (just like what you'd expect from something that says Jump) as follow
void Jump()
{
gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(, 0f, 5f,) ForceMode20.Impulse);
}```@still tendon you didn't understand my point you should ask question if you're not sure you understood what I explained.
In your Update() put this
if (Input.GetButtonDown("Jump")
{
Jump()
}```
and define your Jump method like this
```csharp
void Jump()
{
gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0f, 5f), ForceMode2D.Impulse);
}
if you read the code above it makes sense because in your Update() which is literaly "Update every frame and see if something changed in the code" you call IF I press Jump button THEN you jump
you don't need to check if you're jumping when jumping this doesn't make any sense, do you understand my point?
Think of it as if you code for someone who don't know anything about computers
if I press Key.JumpKey then Jump() nothing more
make it english
like even if the person knows nothing she should still understand
void Update()
{
if (Input.GetButtonDown("Jump")
{
Jump()
}
}
void Jump()
{
gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0f, 5f), ForceMode2D.Impulse);
}
@still tendon but you have to understand why I did it like this
did you understand? I can't make it simpler
which part don't you understand?
a method is defined like this:
access modifier (public or private) which you don't have here
void | return types (what your method will return, void is to create a method that just executes stuff without giving back data somewhere else in the code)
Jump is the method name, how you call it

If you're new to C#
it's a good idea to learn how to make console applications first
scarlet fractal
yeah
tropic inlet
This shows how to create a new console app in Visual Studio 2019
Once you know how to do that
I recommend watching something like Brackey's series on C#
He's using Visual Studio Code rather than Visual Studio 2019, but it's ok.
Same language.
The reason for learning how to code via console apps is because they are lighter.
There are less distractions.
I use console apps whenever I just want to test some C# code
When you use Unity, it's expected that you know every topic in that list
But, of course, you could learn while using Unity if u want

I don't see anything in the code that should cause issues. However, Unity doesn't update those if there's any errors (including in other scripts). So check the console for those, if any.

you check if groundCheck is null
still tendon
oof but its a good game ur working on though
spring ledge
That checks if groundCheck.gameObject is null, yes
And if groundCheck itself is null it'll error
๐
still tendon
so how would i fix
spring ledge
check if groundCheck isn't null
spring ledge
What did you try
still tendon
by deleting return false;
spring ledge
So
I told you to check if groundCheck isn't null
How do you arrive at deleting return false; to accomplish that
spring ledge
You don't
still tendon
so do i just delete the null
spring ledge
as I said, you're checking if groundCheck.gameObject is null, aka, the if gameObject field of the class that groundCheck is (in this case Collider2D) is null
so in that you're checking if groundCheck.gameObject isn't null
now how do you check if groundCheck isn't null?
still tendon
hm
i think i may know
let me see
actually
idk
public bool IsGrounded () {
if Collider2D groundCheck = Physics2D.OverlapCircle(feet.position, 0.5f, groundLayers) != null);
if (groundCheck.gameObject != null) {
return true;
}
return false;
}
}
i tried that
well it wont work
spring ledge
you have an if there, how do you modify that to check for groundCheck instead of groundCheck.gameObject
still tendon
remove game.object?
spring ledge
Yeah
still tendon
spring ledge
So what code do you ahve now

Well you have to remove that != null) thing again you put in there
after the Collider2D groundCheck = [....] stuff

It's just since the radius for it is .5 and your player is 1. So a .5 radius might not find the ground because it ends right as your player ends, doesn't intersect with the ground. So by moving it down slightly thats better
No, like, the script hitng
Where you set feet and groundLayers an dsuch

That seems right. Click ground and make sure it's on the Ground layer

if gameobjects have the same location, they should be at the same spot as far as I know
could it be that
ur colliders are positioned incorrectly?
like
maybe the collider is distant from ur gameobject's center due to some offset
mystic void
their origin points aren't at the same location
according to the inspector for these two game objects, their position on the x axis are both at 0
the distance between them isn't 0 which is what causes the issue with the knockbacks
spring ledge
How did you manage that ๐ค
They're like 7 units apart horizontally despite both being at 0?
mystic void
I suppose their position might be relative to where they were placed
spring ledge
shouldn't be
Do they have a parent that moves?
Then 0 would be relative to parent
At least in the editor
mystic void
That might be it, they donโt have the same parent
spring ledge
Wheres is the parent at?
And how do you calculate the knockback
transform.position.x should give you world coordinates, not relative to parent
The editor shows relative to parent though when you have it selected

Can someone help me getting every non empty tile in a tilemap (and only in the tilemap) please?
Getting every green cells only (Tilemap Collider 2D) would be cool
I'm trying to check if a tile is part of a tilemap and if it's not empty when I click on it.
Basically what I want is to have a buildable tilemap and build something whenever you click in any of the tiles in this particular tilemap. I tried lot of different stuff but I really can't get anything good
spring ledge
That sounds like a terrible way to do that ๐
You should somehow get mouse position and calculate the tile clicked from that
Then you can access that specific tile directly
Instead o fhaving to build a gigantic list
scarlet fractal
Well yeah I'm really lost here I've been searching since yesterday.
For now I have the mouse position when clicking and I can check if the click position is within the tilemap
but it's an area so it also takes other tilemaps and all
spring ledge
Well I'm not sure if your setup is
scarlet fractal
if (Input.GetMouseButtonDown(0))
{
Vector3 pz = Camera.main.ScreenToWorldPoint(Input.mousePosition);
pz.z = 0;
Vector3Int cellPosition = myTilemap.WorldToCell(pz)
foreach (var VARIABLE2 in myTilemap.cellBounds.allPositionsWithin)
{
if (cellPosition == VARIABLE2)
{
transform.position = myTilemap.GetCellCenterWorld(cellPosition);
}
}
}
scarlet fractal
for now cellPosition is my mouse click position converted to the tilemap
then I check if my click is within the tilemap bounds (foreach) and if click position == a cell within the bounds I set my tower here
the thing is that the foreach is really bad
spring ledge
Well good that you realize that it's bad
scarlet fractal
the mouse click only works in my buildable tilemap but as you can see here if I put a block bottom right I can build everywhere between
spring ledge
presumably you want to use https://docs.unity3d.com/ScriptReference/Tilemaps.Tilemap.HasTile.html with that position you get from WorldToCell
What do you mean with "build everywhere between"
scarlet fractal
it seems to be working.. I can't be believe it's that simple
I found this before but got caught in so much things that I forgot about this method
yeah sorry what I meant is moving. whenever I click on one of the tile in the tilemap it moves the GameObject the script is attached to$
well thank you very much I was searching since yesterday morning I feel so dumb
can't believe I got stuck so long just for this but again thanks a lot!

I have a question, i am making a 2D game, but when i move the object and there are colliders on both objects and in the code if i just have void OnTriggerEnter2D it wont work. Can you help me with this?
this is the exact code private void OnCollisionEnter2D(Collision2D collision)
{
Debug.Log("colided with lava");
Destroy(collision.gameObject);
}
tropic inlet
private means it can't be accessed from beyond the definition of the class
For functions like Update and Start, I just make them private because there is no reason for any other script to access it
still tendon
@clever sky Public fields will be displayed in the editor and can be edited (like this)
Thats the way i can explain it

same thing

Meaning they want it to go "up" on the local up direction, not the global up direction
Presumably
fiery oar
what do you mean with respect to it's rotation?
@grand cove i want it like in 3d we use transform.forward so like that how to use it in 2d
Meaning they want it to go "up" on the local up direction, not the global up direction
@spring ledge yeh but how to do
clever sky
what if you fix this OncollisionExite2D to OncollisionExit2D?
spring ledge
@fiery oar What does transform.forward give you?
clever sky
(there's an extra e in your version)
fiery oar
@fiery oar What does transform.forward give you?
@spring ledge its for vector3 so it wont work
i want it for vector2
spring ledge
@fiery oar What does it give you? Abstractly, not the value
silent bay
nope
spring ledge
@fiery oar Btw, 2d games still use vector3 for gameobjects
grand cove
you can just convert the vector 3 to a vector 2...
silent bay
but i've tryed with and without and the probleme is &&ontheground
fiery oar
you can just convert the vector 3 to a vector 2...
@grand cove how to convert it
grand cove
just put (Vector2) in front of the vector 3 value
silent bay
is there a other function maybe?
grand cove
vector 2 is literally the same thing as a vector 3 but it has 1 less value <.<;
clever sky
@silent bay try and Debug.Log("Jumped") in you collision code to check if it even gets called?

then you can at least see if it stops colliding with the ground

i want the game to be like when i press left it rotates left and when i press right it rotates right and when i press both at the same time it goes in upward direction
@fiery oar i want it to be like the minecraft boat controls

i want the game to be like when i press left it rotates left and when i press right it rotates right and when i press both at the same time it goes in upward direction
@fiery oar something like

but 2D is different from 3D, there is not forward @fiery oar you have to calculate that your self or rotate the game object and keep using transform.up as "forward"

it works
i want no gravity in rigidbody2d so it moves in the direction for ever
how can i make it to come at rest in the script
public class Ship_Controller : MonoBehaviour
{
public Rigidbody2D shipRB;
public float speed = 1;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame

its my whole script

I believe you can remove gravity from the inspector

@clever sky so i fixed it but it doesn't fucking work

How do i add gravity and movement to my game

This is literally stuff you learn from basic tutorials @fiery oar
https://learn.unity.com/search?k=["tag%3A58088f5f0909150077ca2bc6"]

@clever sky so i fixed it but it doesn't fucking work
@silent bay but does it print?
silent bay
so I think i'm just gonna rewrite everything
fiery oar
i know
spring ledge
Thats why I asked you what forward returns btw
silent bay
heu
fiery oar
as z axis is towards the screen
still tendon
How do i add gravity and movement to my game
clever sky
then the collision doesn't exit
spring ledge
Forward returns the positive Z-axis. What has 2D? x, and y. So we do'nt need forward. Whats up in 2d? y. Whats the transform for up?
fiery oar
i have my issue fixed
clever sky
@spring ledge isn't it just .up?
fiery oar
yes
silent bay
do you think the problem is from "collision2D"
grand cove
How do i add gravity and movement to my game
@still tendon Read up on rigid body and use the unity beginner tutorials.
clever sky
The collision doesn't trigger
silent bay
oh
clever sky
I personally don't know how to trigger collision, I just know how to print statements my way to victory ๐
silent bay
gonna check

if (Input.GetKey("right"))
{
shipRB.velocity = transform.up * speed;

here i want my gravity to be off in the inspector by doing so the object continues to travel in the direction forever so how to gradually decrease the velocity
fiery oar
public class Ship_Controller : MonoBehaviour { public Rigidbody2D shipRB; public float speed = 1; // Start is called before the first frame update void Start() { } // Update is called once per frame void Update() { if (Input.GetKey("left")) { if (Input.GetKey("right")) { shipRB.velocity = transform.up * speed; Debug.Log("working"); } } } }here i want my gravity to be off in the inspector by doing so the object continues to travel in the direction forever so how to gradually decrease the velocity
or the second way to say is how to implement gravity in code
grand cove
Christ, people don't even do basic tutorials before they start blasting questions here any more, I'm off.
clever sky
@spring ledge does gameobjects just casually have collisions for free? ๐ฎ
spring ledge
Only if you put in colliders?
clever sky
That makes sense
fiery oar
Christ, people don't even do basic tutorials before they start blasting questions here any more, I'm off.
@grand cove i have basic knowledge but i want the efficient code that's why im asking
my issue solved
spring ledge
You're literally asking how to dampen velocity over time. I'm not sure that counts as basic knowledge ๐
grand cove
If you know the basics, then you should know what transform does and how to use it to "fake" gravity.
still tendon
So I made a platform collider so that you could go through a ceiling and floor, but if you go through the floor, it does not stop. I want to turn it off right after they go through it.
Any help?
scarlet fractal
@still tendon if I understand what you say you could use the OnTriggerEnter2D method (requires a Rigibody and a Collider 2D on your player)
then you could use the collider that's given in parameters and use .Compare("yourPlayerTag") as a condition and inside this if put your .enable = false or something
still tendon
On what event would I make it false though @scarlet fractal
scarlet fractal
whatever you're using to make your collision turn it off
still tendon
okay thanks

Do you mean Mathf.Abs(Input.GetAxis("Horizontal"))? Because Mathf.Abs("Horizontal") literally just gives it the string "Horizontal" when it wants a float
tame lava
Is there a way to select all **particles **in a certain radius? The same way as OverlapCircleAll finds all colliders.
tame lava
ans:
var droplets = new ParticleSystem.Particle[rain.particleCount];
var num = rain.GetParticles(droplets);
for (var i=0; i<num; i++)
{
if (Vector2.Distance(droplets[i].position, rb.position + rb.centerOfMass) <= radius)
{
droplets[i].remainingLifetime = 0;
}
}
rain.SetParticles(droplets, num);
@tame lava Use DistanceSquared and square your radius before comparing it
(Sort of depends on how many particles you have and how often you do that for it to matter though :P)
slate token
how would i go about designing a collision system for a grid ship like this https://gyazo.com/168659d73d306c6706b08963f242b998 ?
i thought about having the parent having a rigidbody and a composite collider, but i don't know how i would go about checking collision for individual blocks (as they can be damaged individually)
tame lava
@spring ledge about 300 particles, every frame. Is DistanceSquared faster or something?
Oh, makes sense, it just doesn't need to take a square root every time.
spring ledge
Yeah
tame lava
Idk if it's me being dumb but it
Cannot resolve symbol 'DistanceSquared'
var distSquared = Vector2.DistanceSquared(droplets[i].position, rb.position + rb.centerOfMass);
Vector2.cs doesn't have it.
spring ledge
๐ค
spring ledge
@tame lava Not sure why they don't have that, but you can do distSquared = (droplets[i].position - (rb.position + rb.centerOfMass)).sqrMagnitude instead
Oddly the sqrMagnitude docs even note that its faster than magnitude, and Distance says it's the same as (a-b).magnitude. So no clue why they decided to have no DistanceSquared

Hey I have a turret GameObject with this script attached that strikes every 2s and slows every enemy GameObject within its radius (Tower Defense game). My only issue is that when an enemy exits the slow radius his speed goes back to normal but almost of the enemies have their speed reduce once after it.
Anyone knows what I could do? Or at least see my OverlapCircleAll in my Scene to see if it match my turret Circle Collider 2D?
public class TurretTest : MonoBehaviour
{
void Start()
{
StartCoroutine(SlowAttack());
}
IEnumerator SlowAttack()
{
yield return new WaitForSeconds(2);
Collider2D [] colliders = Physics2D.OverlapCircleAll(transform.position, 7f);
if(colliders.Length > 0)
{
foreach (var VARIABLE in colliders)
{
if (VARIABLE.CompareTag("Enemy"))
{
Debug.Log(VARIABLE.name);
SlowEnemy(VARIABLE);
}
}
}
StartCoroutine(SlowAttack());
}
private void OnTriggerExit2D(Collider2D other)
{
Debug.Log(other.name + "EXITED RADIUS");
var script = other.GetComponent<EnemyMovement>();
script.Speed = script._defaultSpeed;
}
void SlowEnemy(Collider2D other)
{
var script = other.GetComponent<EnemyMovement>();
if (script.Speed > 2)
{
script.Speed = script.Speed - 0.5f;
}
}
}```@spring ledge thanks!
spring ledge
@scarlet fractal Thats an odd way to use coroutines? why not just while true it
@scarlet fractal Also not sure what you mean. Enemies stay slowed?
heavy token
@scarlet fractal that system is gonna break once you have more then 1 slow effect, because the Turret removes all slows and not just it's own. I would apply slows as a Debuff, but that would be a little to advanced for you I think.
still tendon
someone wanna created a game 2D
spring ledge
True
scarlet fractal
@heavy token yeah you're right didn't think of this, I think I'm gonna search for a debuff tutorial then.
Maybe I could update an isSlowed bool on my enemy so that when it's false my enemy starts recovering his speed bit by bit instead of resetting to the default value so that if he enters in another slow turret's radius it goes back to isSlowed?
@spring ledge wdym while? I used OnTriggerStay2D() before but it ran my slow code every time.
spring ledge
IEnumerator SlowAttack()
{
while (true) {
yield return new WaitForSeconds(2);
Collider2D [] colliders = Physics2D.OverlapCircleAll(transform.position, 7f);
if(colliders.Length > 0)
{
foreach (var VARIABLE in colliders)
{
if (VARIABLE.CompareTag("Enemy"))
{
Debug.Log(VARIABLE.name);
SlowEnemy(VARIABLE);
}
}
}
}
}```I don't really understand how this will change? Actually my slow is executed 1 more time than it should so would while(true) change this/what would it change?
spring ledge
It just mean you're not constantly making a new coroutine if you can keep one running ๐
scarlet fractal
so this will only slow my enemy once? what I want is a turret that hit the ground and slow enemies in its radius a bit every time it hits the ground while they're in the turret's radius
maybe I could also change the behavior to make just slow every enemy inside it to a fixed value and then whenever they get out they progressively get their speed back
heavy token
@scarlet fractal he means that instead of calling your Coroutine again at the end of your Coroutine you could have it in an endless loop instead.
scarlet fractal
oh that's just better in term of memory usage? @spring ledge I'm not thinking of performance for now but thanks this should be way better performance wise
heavy token
@scarlet fractal a debuff class would have a baseDuration, timer and enemy it is affecting. If it's a slow debuff it would have a slowAmount value, when it is applied reduce the speed of the enemy by X amount. When the duration reaches 0 add X to the enemies speed again.
But you would also have to learn about Inheritance
scarlet fractal
So like if the enemy is in the radius he will be slowed by 5 for 3 seconds but only once if he's already slowed
and when isSlowed is false he progressively gains his speed back

@still tendon you should learn C# before Unity. NullReference means the reference you gave is null which means nothing. In your error it's written Scripts.Update() so this happens in your Update() method. The problem probably comes from _rigidbody. Did you add a Rigidbody in your inspector?
Also you can debug yourself: is this problem happening on start or when I press the Jump key? If it happens when you press your Jump key then the problem comes from something inside your Jump key condition.
spring ledge
An f there doesn't matter though ๐ค
vocal condor
But the null reference exception definitely does ๐
Guessing you do not have a Rigidbody2D attached to your GameObject..
vocal condor
"it worked" isn't relative to the error you posted..
spring ledge
fmatters on assignment. For example float abc = 0.3; this would need the f. Because without any addition that 0.3 is a double, not a float. You're assigning it to a float, so you'd potentially get wrong data as a float is less precise than a double. Thats why it needs you to denote that you're putting a float by adding f. Comparing double to float works without f's
still tendon
Why would you argue, when it works lmao
spring ledge
You sure you didn't assign a rigidbody during those tests or something ๐
Lets do it the science way
remove the f again
Does it break?
still tendon
Yes

Because we aren't.. we're explaining your error.. not feeding self justifications ๐คทโโ๏ธ

Also you should use std::cout; there. using namespace std; is incredibly bad practice
๐
still tendon
Couldn't care less, using namespace std; is way faster
and much more efficient
๐
scarlet fractal
That's what I told him
tropic inlet
using std::cout;
For beginners, using namespace std; is fine. If they don't even understand what a variable, function or scope is, it's unlikely that they are writing any large projects that are vulnerable to name clashes.
When they start becoming intermediate, and they start writing larger programs, they'll begin to see the benefits of being explicit due to how the creators of the standard library dumped so much into one namespace.

You are the first person in ages
that has used this phrase correctly
Everyone else says "I could care less", which is the opposite of what they intended to convey

hello, could someone help me?
I am producing a project where I need to throw objects and after a while they self-destruct, but all very quickly, since I send teleport. I can normally destroy the first prefab that the player shoots, but the next one is intact, being deleted only from the list and not being destroyed, I have been trying to solve this problem for a long time and I am new to programming.
My attempt:
{
yield return new WaitForSeconds(timerRange);
rb2b.constraints = RigidbodyConstraints2D.FreezePosition;
yield return new WaitForSeconds(timerRange);
Destroy(playerController.projectiles[playerController.projectiles.Count - 1]);
playerController.projectiles.RemoveAt(playerController.projectiles.Count - 1);
}```
I can't use "Destroy (gameObject);" since he gives the following error and I need the player to teleport as soon as possible: "The object of type 'GameObject' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object."
Sorry for my bad English, I'm not very fluent.

transform.position = Vector3.SmoothDamp(transform.position, targetPosition - new Vector3(0, 0, 10), ref currentVelocity, followDuration, maximumFollowSpeed);
}```
**targetPosition.x - player.position.x - (viewPortSize.x / 2 * Mathf.Sign(distance.x));** and
**targetPosition.y - player.position.y - (viewPortSize.y / 2 * Mathf.Sign(distance.y));** have red squiggly lines under it. I am using code from 2019, could it be outdated?
EDIT: Nevermind, the "-" right after **targetPosition.x** and **targetPosition.y**, was supposed to be an equals

Guys anyone know of a tutorial about GetComponent for Tilemaps?
I've found the reference.
Is there a way to assign a script to a tile or tile map. Should you create a likewise grid of tiles by returning TileMap.cellBounds and simulating properties?
Wait, if I create a huge array using TileMap properties from the TileMap I can calculate the exits from each tile
Then pathfinding is easy.

How can i get all objects in a spectify radius of a object?
vocal condor
Circle cast or sphere cast if your objects have colliders.
remote moth
Circle cast or sphere cast if your objects have colliders.
@vocal condor thx, but i've already figured it out myself
how can i create a object by c# script?
vocal condor
You can create using instantiate or keyword new.
remote moth
new GameObject?

i have a problem, why i have this All compiler errors have to be fixed before you can enter playmode! UnityEditor.SceneView:ShowCompileErrorNotification()
sudden cedar
think
vocal condor
Fix them from top to bottom..
remote moth
how can i give this gameobject a texture by script?
vocal condor
.... You need to start searching for tutorials online...
remote moth
ok .-.
vocal condor
These are pretty basic questions..
A renderer allows an object to be displayed.
There are many types.
They are all components.
sudden cedar
what am i supposed to do with the code from the link you sent me i don't understand
vocal condor
It wasn't for you.. you need to fix your errors.
Fix them from top to bottom..
@vocal condor
vocal condor
Scroll up and read the first error. I'm assuming you kept trying to play the application and unintentionally hid the original error.
sudden cedar
i have nothing
vocal condor
I see six errors being reported.
sudden cedar
look nothing
vocal condor
Double click and check the details pane below.
Clear the console as well.
Is this a new project?
sudden cedar
nop i crated 2 week ago
vocal condor
Not entirely sure, it's not a script error (especially related to 2D), more like a setup error. Post your question in #๐ปโunity-talk.. Not much folks will be able to give you the exact answer but there are others on the net with your problem and the solutions aren't too solid..

Does anyone know how to make 2d ragdoll physics for a stickman?
I just started Unity like this week and I want to make a 2d ragdoll game so i would appreciate any help
remote moth
How can I make the object go in the direction he is facing?
scarlet fractal
@remote moth I think you could use Quartenion. Maybe try to Debug.Log Quartenion.Identity to see where he's facing
Hey I currently have a script that spawns a GameObject where I click but I can spawn an infinite amount of this GameObject on top of each other, is there a way to check if there's already a GameObject at my mouse position? I don't think creating a List of every GameObject I spawned would be a good practice performance wise.

@scarlet fractal you want that it create one object wenn you click?
plush coyote
You could raycast to the mouse or something simple like that
scarlet fractal
No I already have this. My issue is that I only want to create one per position I don't want to have GameObjects on top of each other
plush coyote
If it is a grid based game, having a 2D array of your map would be a good option
plush coyote
If you actually want an object to take up one grid position, then yeah, have a 2D array of your map
When you spawn the object, you can round the position to the nearest grid position and set that position to "taken" or whatever
scarlet fractal
my only condition for now is
if (buildableTilemap.HasTile(mousePosition)```then just don't instantiate something if the rounded position is taken
scarlet fractal
ok I'll try this thank you
remote moth
he should go not completly in the correct direction .-.
Rotate to the object:
Quaternion GetRotationToTarget(Transform target,Transform i)
{
Vector3 targ = target.transform.position;
targ.z = 0f;
Vector3 objectPos = i.position;
targ.x = targ.x - objectPos.x;
targ.y = targ.y - objectPos.y;
float angle = Mathf.Atan2(targ.y, targ.x) * Mathf.Rad2Deg;
return Quaternion.Euler(new Vector3(0, 0, angle));
}
Move in this direction:
transform.Translate((transform.up / 2) * 1);
that's a lot of code to get the direction to the target
Quaternion GetRotationToTarget(Transform target,Transform i)
{
Vector2 dirToTarget = (target.position - i.position).normalized;
float angle = Mathf.Atan2(dirToTarget.y, dirToTarget.x) * Mathf.Rad2Deg;
return Quaternion.Euler(new Vector3(0, 0, angle));
}
he got still in the wrong direction
plush coyote
But, you just want it to go towards the target?
remote moth
But, you just want it to go towards the target?
@plush coyote yes
plush coyote
Vector2 dirToTarget = (target.position - transform.position).normalized;
transform.right = dirToTarget;
transform.Translate(transform.right * 5f * Time.deltaTime); // 5f is just some arbitrary movement speed number
that's the whole code
No need for quaternions or angles
remote moth
and can i do that he rotate in the direction?
plush coyote
this code also does rotation
remote moth
this code also does rotation
@plush coyote ok, thx
plush coyote
Use it all the time for my 2D projects
but yeah, it doesn't really make sense that it sets it
or at least, you wouldn't think it would
given the rest of unity's properties
remote moth
he don't move correctly by me, i want to set once the direction
plush coyote
No clue what you mean by that
remote moth
by creating the object
spring ledge
I mean, it can't change transform.right without changing rotation and such to match, I just expected it to be a read-only thing
plush coyote
thats what I meant ^ @spring ledge
given the rest of unity's properties, you would think its read only
remote moth
No clue what you mean by that
@plush coyote i mean that
spring ledge
Whats that
plush coyote
Two black squares
scarlet fractal
@plush coyote since I have a GameObject manager I just added my GameObject position to a List of positions whenever it's instantiated. Does the job for now I might create a class with different methods later
plush coyote
nice
remote moth
i mean that
he does not hit the object, but passes it
scarlet fractal
through it maybe?
spring ledge
next to it probably, since through it would be collisions
spring ledge
What passes what ๐
remote moth
he move in the direction of the blue arrow, but he should in the direction of the red arrow go
remote moth
and are these objects children of any other object
@plush coyote he has not childrens
create projectile
void SpawnProjectile(Collider2D[] enemys)
{
GameObject a = Instantiate(shootPrefab) as GameObject;
a.transform.position = new Vector2(self.position.x, self.position.y);
for(int i = 0;i < 100; i++)
{
Vector2 dirToTarget = (GetNearst(enemys).position - a.transform.position).normalized;
a.transform.right = dirToTarget;
}
}
Why is this looping 100 times
remote moth
becaus the old rotation variant
@remote moth but wenn i do execute it once for a object has he not rotate
plush coyote
well, what is the code on the projectile?
That doesn't make sense, the loop doesn't do anything
remote moth
well, what is the code on the projectile?
void Update()
{
if((self.position.x < -15f)||(self.position.x > 15f)||(self.position.y > 8f)||(self.position.y < -8f))
{
Destroy(this.gameObject);
}
transform.Translate(transform.right * 5f * Time.deltaTime);
}
when he is right to him, then the projetile move correctly, but...
..but, when he is over, under or left of him the, he move not so as he should
remote moth
mean you this?
spring ledge
No
plush coyote
why does it have gravity
remote moth
No
@spring ledge what then?
plush coyote
is that the projectile?
spring ledge
the actual object in the scene
remote moth
why does it have gravity
no, i have gravity set to 0
plush coyote
Ah ok
remote moth
A screenshot of that
@spring ledge of the scene?

Getting nearest enemy method has to be wrong. Everything else seems fine
remote moth
hmm should work then
nope
Getting nearest enemy method has to be wrong. Everything else seems fine
why is this method wrong?
Transform GetNearst(Collider2D[] Enemys)
{
Transform Nearest = null;
float distance = 1000f;
foreach (Collider2D x in Enemys)
{
float x_distance;
float y_distance;
Transform obj = x.transform;
if(obj.position.x > self.position.x)
{ x_distance = obj.position.x - transform.position.x;}
else{ x_distance = self.position.x - obj.position.x;}
if (obj.position.y > self.position.y)
{ y_distance = obj.position.y - transform.position.y; }
else { y_distance = self.position.y - obj.position.y; }
float NewDistance = y_distance + x_distance;
if(NewDistance < distance)
{
distance = NewDistance;
Nearest = obj;
}
}
return Nearest.transform;
}
Thats an odd way to get distance
remote moth
Thats an odd way to get distance
yes, this my way to get the distance xD
remote moth
Trying to think if that even works
yes this work
No, it does not
why not?
i have try it, this method work
plush coyote
Yeah, his old rotation method was like that too
tons of manual calculations that could have been done in 1 line

Say one object is at 0,0, the other at 9,1, so it's 9 tiles away from the first object. but you'd calculate that as 9-0, 1-0, then 9+1 = 10
Another object is at 5,6, so closer. But 5-0 = 5, 6-0 = 6 -> 5+6 = 11. So according to that it would be further away
plush coyote
literally
float distance = Vector2.Distance(obj.position, self.position);
if it feels like you are reinventing the wheel, you are probably doing something wrong (or there is a much easier way of doing it)
remote moth
tons of manual calculations that could have been done in 1 line
this is, because that i unity yet not long using
remote moth
but you could always google "get distance in Unity"
i have it so do, how i do it in python previously
