[swift crag]

make sure you've followed every step in the VSCode instructions

[meager steeple]

is it possible to have text grow and shrink in a loop, a bit like the terraria logo

[swift crag]

sure. i'd just set its localScale

transform.localScale = Vector3.one + Mathf.Sin(Time.time) * 0.1f * Vector3.one;

this would go up and down between 0.9x and 1.1x scale

[glass urchin]

okay weird as soon as I signed in to Microsoft to use c# dev kit it started working

[swift crag]

that isn't necessary, but it might've caused your editor to restart

[glass urchin]

I had already restarted it

[rotund garnet]

Cant figure out what causes this error...

[swift crag]

This is Unity's fault. Just restart the editor and it should clear up.

something went wrong with a graph window (like the shader graph editor)

[swift crag]

Mathf.Sin's input is in radians, not degrees, so this will do a full cycle every 2*pi seconds

Mathf.Sin(Time.time * Mathf.PI * 2)

This would cycle once per second.

[meager steeple]

so the scale is going from 0.9 to 1.1 what if i want it to vary at a bigger number, like from 2.9 to 3.1

[swift crag]

more generally

transform.localScale = baseScale + Mathf.Sin(Time.time) * scaleRange * Vector3.one;

where baseScale is a Vector3 and scaleRange is a float

Vector3 baseScale = Vector3.one * 3;
float scaleRange = 0.1f;

e.g.

[meager steeple]

right thank you so much

[glass urchin]

I wanna create a HingeJoint using a script, but it won't let me set the attached gameObject because it's readonly

[swift crag]

you can't set the gameObject property of a component

that's also irrelevant when setting up a hinge joint

a hinge joint is attached to a rigidbody or an articulation body

[glass urchin]

oh right

[daring stream]

Hello everyone! I wanted to ask, how can I display a character's health using TMP? I've figured out the part where I can change the UI text to whatever i want through code. But I can't figure out how to change the Health float to a string that only shows the Health without any decimals. So basically as an integer

[languid spire]

ToString("N0")

[signal narwhal]

Or do health.text = "Hp: " + health;

[polar acorn]

That doesn't actually solve the problem

They want to display it as an int with no decimals. You'd need to use a ToString formatter for that one

[signal narwhal]

I did it with this

[polar acorn]

Again, that would just display the entire number. Nothing there converts it to int or rounds it or drops the decimals

[signal narwhal]

Oh nvm i thought the health float was an int

[rocky canyon]

ToString() = no decimals ToString(F1) = 1 decimal, and so on

[amber spruce]

players = GameObject.FindGameObjectsWithTag("Player");

is it possible to have that also add objects that are disabled that have the tag Player

[meager steeple]

how would you change a button's properties on hover, would it have to be code or could you do it in a simpler way?

[half patrol]

Hello, beginner here so i face this issue. When player is jumping he falls down like in a picture. how to prevent this? it's rigidbody2d

`public class Player : MonoBehaviour
{
private float moveForce = 10f;

private float jumpForce = 11f;

private float movementX;

private Rigidbody2D myBody;
private Animator anim;
private SpriteRenderer sr;

private string WALK_ANIMATION = "Walk";

private bool isGrounded;
private string GROUND_TAG = "Ground";

private void Awake()
{
    myBody = GetComponent<Rigidbody2D>();
    anim = GetComponent<Animator>();
    sr = GetComponent<SpriteRenderer>();
}

void Start() { }

void Update()
{
    PlayerMovementKeyboard();
    AnimatePlayer();
    PlayerJump();
}

void PlayerMovementKeyboard()
{
    movementX = Input.GetAxisRaw("Horizontal");
    transform.position += moveForce * Time.deltaTime * new Vector3(movementX, 0f, 0f);
}

void AnimatePlayer()
{
    if (movementX > 0)
    {
        anim.SetBool(WALK_ANIMATION, true);
        sr.flipX = false;
    }
    else if (movementX < 0)
    {
        anim.SetBool(WALK_ANIMATION, true);
        sr.flipX = true;
    }
    else
    {
        anim.SetBool(WALK_ANIMATION, false);
    }
}

void PlayerJump()
{
    /*
        adding force to rigidbody using vector to tell player to jump in 2D
        ForceMode2D.Impulse tells it to use force right away
    */
    if (Input.GetButtonDown("Jump") && isGrounded)
    {
        isGrounded = false;

        myBody.AddForce(new Vector2(0f, jumpForce), ForceMode2D.Impulse);
    }
}

private void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.gameObject.CompareTag(GROUND_TAG))
    {
        isGrounded = true;
    }
}

}`

[amber spruce]

i have fixed this by disabling the z rotation in the rb2d not sure if that would work for you

[eternal needle]

You don't need this method at all. If the players already exist in scene then just drag the reference in. If you're instantiating them, it returns a reference so you can just directly add it to the list.
Or have the players notify this code that they exist

[half patrol]

how can i do this?

[amber spruce]

well the players are from a different scene

[half patrol]

thank you

[eternal needle]

That doesnt stop you

What's the use case?

[amber spruce]

im trying to have them be disabled until they select their character so when they spawn in i disable them and when they select their character i reenable them

[amber spruce]

problem is they are spawned in with a network manager

[half patrol]

btw, disabling it from unity engine is enough right? i dont have to do this in code

[amber spruce]

yeah disabling it in unity is good

[half patrol]

it worked. thank you pancakes

[amber spruce]

your welcome

[eternal needle]

Using Ngo? The network manager has a list of all spawned player objects then

[amber spruce]

wait it does

how can i acces it

[eternal needle]

I'm not on my pc, google should lead you from here

[glass urchin]

how to remove the red lines???

[eternal needle]

I forgot exactly where it is

[glass urchin]

it keeps saying im not using mscorlib and shit

[swift crag]

I think your editor threw up

VSCode sometimes does that for me

It completely loses the plot and can't recognize anything

give it a restart

[glass urchin]

ahhhh

it almost worked then it didnt

is there a way to check collisions outside of the collision system? like to check discretely if two specific trigger colliders are intersecting on load?

the animator not playing nice with the physics engine is starting to piss me off

[daring stream]

gives me an error message that states that " A field initializer cannot reference the non-static field........."

[swift crag]

you can use https://docs.unity3d.com/ScriptReference/Physics.ComputePenetration.html to ask if two colliders overlap in a certain pose

[swift crag]

you're trying to initialize a field

the field initializer runs once when the object is constructed

that doesn't sound like you want anyway

you want to set the text constantly

health.text = "Hp: " + health; will work just fine in Update

[swift crag]

public int x = 3; // fine
public int y = x; // error

these are field initializers

[robust kelp]

is it possible to replicate source engine stafing in unity using rigidbody?

[glass urchin]

do I really have to pass in ALL those variables?

[swift crag]

Yes.

I'd just store the values into variables and then pass those variables in, as the example shows

[glass urchin]

So if I have a bunch of colliders and I need to check which ones intersect which ones should I just have one script in the parent that checks all instead of a script in each gameobject that has the colliders?

[swift crag]

I suppose that's how I'd do it, yes.

[rocky canyon]

ya, keep ur logic tight

[glass urchin]

my aim is for each collision on load, I create a new empty and attach the newly created empty to both game objects by a hinge joint. just dont wanna do the entire area of this level manually

[rocky canyon]

if u have a problem much easier to debug a singular script vs 3 or 4

[daring stream]

Ohh, that makes sense. Thanks!

[glass urchin]

this is something I can do manually but I want to be able to adjust all variables on the fly

[long scarab]

Is there a way to change Button state to selected or other color tints in code?

I looked at some documentation

can't find any

maybe I should use a toggle insted 🤔

[rocky canyon]

https://gist.github.com/SpawnCampGames/f854b2e0313aa0fcaeefe619dd429f53
Hello, I've been working on this setup for a while, and i finally got it working somewhat how i want..

• when you single click on an object (if its selected it gets deselected and vice versa)
• when you click and hold (on the object) (if its selected we open a menu)

so far i have this raycast that detects if its selectable (using an interface)

• when we first click we get teh object so we can check wether or not its selected
• this also triggers the (holdingAction) so we can decide whether we release early (short click) or release it later (long click)
  The dragging feature is where I'm stuck.. b/c I need a way to know whether or not we are dragging the mouse (away from the selected unit)

but I have the mousebutton down (which starts the raycast) so I'm a bit confused on where or how would be the best way to do it..
The initial MouseButtonDown (is on line 73)
The Raycast in which the stuff starts happening is on line 149
The Raycast sets the booleans which are monitored in the update

sorry, theres so much information in here, I just wanted to explain it thoroughly..
any questions, suggestions, or follow-ups you can ping me

[rocky canyon]

you can use a toggle
on a button u can set its interactivity
myButton.interactable

but u probably also need to do something with the event system, letting it know ur focusing on a button

[long scarab]

yeah but I dont want to make it non clickable

I just wanted to change its colour

so basically a toggle haha

but thanks for reply!

already writing listener for toggle 😄

[glass urchin]

if a capsulecollider is on the x axis does that mean the quaternion is identity?

or is that the y axis?

or is it always identity unless changed?

[swift crag]

A capsule collider on an unrotated object will align with the Y axis

[glass urchin]

I set mine to X

[swift crag]

oh right, you can change it

[glass urchin]

does that change the rotation?

since the axis is a propety of capsule collider?

[swift crag]

use the rotation of the transform for the collider

[glass urchin]

okay

[swift crag]

Unity just needs to know how the collider's object is positioned and oriented

similarly, I don't think you need to do anything with the Center of the collider

[glass urchin]

so then assuming the colliders intersect, I need to check if I already created an empty that collides with them, since each empty will be connecting to up to 4 rigidbodies

is this considered complex?

[rocky canyon]

lol, how do you feel about it

[swift crag]

sounds like it could become a giant headache very quickly.

I would first build a list of all rigidbody-rigidbody pairs, then create joints on them afterwards

[rocky canyon]

ya, i was gonna say, id try to get it working quickly.. and not touch anything afterwards 😄

[swift crag]

separate the "finding pairs" logic from the "connecting pairs" logic

[rocky canyon]

but keeping a list is def smart

[swift crag]

this will also let you manually define pairs if you want to

also, I'd suggest just making a method that checks for an overlap and nothing more

[glass urchin]

I'm testing my script with just a set of 4

Well, yes, but idk how to STORE those pairs

[rocky canyon]

multiple colliders and multiple physics calls can get very hard to debug..

[long scarab]

I made a custom class for my pairs

[rocky canyon]

just try to keep ur stuff straight

[glass urchin]

I have 4 days and I have more to do after this area.

[swift crag]

public static bool TestOverlap(Collider first, Collider second) {
  return Physics.ComputePenetration(
    first, first.transform.position, first.transform.rotation,
    second, second.transform.position, second.transform.rotation,
    out var _, out var _
  );
}

now you have a nice simple TestOverlap method

[glass urchin]

why position and not localposition?

[rancid tinsel]

im wondering if the way im coding here could cause a bug if the player was to purchase an upgrade that increases their attack speed while the coroutine is running?

[swift crag]

because it works with world positions

you're asking "would these two collider overlap if they were positioned and rotated in this way?"

you tell it the world position of the colliders

[rancid tinsel]

cuz im assuming it would take the A value of the variable and count down those seconds, while ignoring the new value B

[hard hornet]

it'd count the old value

[rancid tinsel]

yeah i thought so

thanks

[swift crag]

I wouldn't consider that to be a huge problem

you already shot the weapon

[rocky canyon]

nah, the player wouldnt even notice i bet

[swift crag]

the upgrade will kick in next time you fire

[rocky canyon]

or be buying upgrades and shooting at the same time anyway

[swift crag]

Ah, I do see the problem though

[hard hornet]

you could also do StopCoroutine() when you buy an upgrade

[swift crag]

The sprite wouldn't match the actual ready state of the weapon

[glass urchin]

what's out var _?

[swift crag]

Why not just make the sprite change based on timeUntilFire?

[swift crag]

ComputePenetration has two out parameters. An out parameter lets the function write values into your variables.

You can declare the variable as part of the function call by including a type

[wintry quarry]

You should use a bool you set and unset inside Shot animation instead of checking the time outside

[rocky canyon]

i think _ just means default

[swift crag]

I used var, since it's obviously a float

float would also be fine

[rancid tinsel]

the tower in question is a balista, i want the sprite with the arrow on it to be loaded in earlier, but im not sure yet

[swift crag]

and then since I don't care about the result, I use _

[rancid tinsel]

i might just do that but i want to test which one feels better

[swift crag]

https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/functional/discards

_ is used when you don't actually want a variable

[glass urchin]

you lost me

okay

so it discards the minimal orientation and distance?

[long scarab]

is the discard discarded tho?

as in GC

[swift crag]

public void SetToThree(out float result) {
  result = 3;
}

void Foo() {
  float myVar = 0;
  SetToThree(result);
  Debug.Log(myVar); // "3"
}

[swift crag]

floats aren't ever garbage collected anyway, since they're just values

i don't know exactly what the compiler will do

there's also no real reason to worry about that

[rocky canyon]

its just a float, or bool.. yea GC doesnt matter in that case

[rancid tinsel]

there are 2 sprite renderers in children, any way to specify which one?

[swift crag]

Correct. We MUST pass variables to the ComputePenetration method, so we use _ to indicate that we don't care about the results at all

we can't just leave the parameters out

[swift crag]

reference them directly with two SpriteRenderer fields

[long scarab]

so what is the difference between using _ and using proper variable

[swift crag]

not much, but it makes it clear that we don't care about the values

[long scarab]

true haha

[rocky canyon]

well considering ur using GetComponent (the singular version) thats only gonna return the first one

every time

[rancid tinsel]

is there a different thing i can use to achieve what i want?

[rocky canyon]

u could use the plural version to get all of them.. and then ud have to do another check to get the right one

else id use a different method of finding it..

using a blank Monobehaviour as a tag.. or using a regular unity tag

[glass urchin]

it says no bc its c# 6.0

[swift crag]

what do you actually want?

not "get two sprite renderers"

[swift crag]

what version of unity are you using?

[rocky canyon]

and search for it first.. and then grab the component from the one u know its from

[glass urchin]

2017.4

[swift crag]

aeugh

okay, just use out float whatever or something

[rancid tinsel]

to find the second sprite renderer, because its deeper in the hierarchy of the children objects

[glass urchin]

that cant change

[swift crag]

what are you actually making your game do here?

[rancid tinsel]

the tower is basically split into the background and then the bit that rotates

[swift crag]

If you can assign the reference manually, just do that

[SerializeField] SpriteRenderer rotatingPart;

drag the sprite renderer in and you're golden

[rocky canyon]

^ best bet

[rancid tinsel]

it will be a prefab so i dont think i can do it manually

[swift crag]

sure you can

do it in the prefab

[rocky canyon]

if its inside the prefab

[rancid tinsel]

ohhhh

right

got it

[rocky canyon]

then thats all that matters

[swift crag]

prefabs would be useless if you couldn't assign intra-prefab references

[rocky canyon]

that would suck

[rancid tinsel]

so i dont need the Start() function all together

[rancid tinsel]

since i just assign it in inspector?

[wintry quarry]

Best practice is never to really reach "inside" other objects like that anyway. Put a script on the root of the prefab. Give that script the references (to inside itself). And have external code only interact with that script.

[swift crag]

ah, the entire thing is disallowed

okay, just declare two float variables before you call ComputePenetration

and then pass them in as , out var1, out var2);

[glass urchin]

its vector3 and float

[swift crag]

ah, then Vector3 and float :p

[rocky canyon]

var var1 = Vector3.zero;
var var2 = 0f;```

Vector3 var1 = Vector3.zero;
float var2 = 0f;```

[glass urchin]

still not working

how do I do that

[rancid tinsel]

is this a good workaround to the player buying more attack speed during the animation?

[glass urchin]

says its already defined in this scope

[swift crag]

show me your code

i have no idea what you've written

[rocky canyon]

lol...

[swift crag]

Pass them like this.

Do not include the types.

That's trying to declare new variables named var1 and var2

also, your IDE is having a meltdown right now

[rocky canyon]

lmao i'd say

[glass urchin]

I know

[swift crag]

try regenerating project files from the External Tools menu and restarting the editor

[rocky canyon]

i can't really tell whats kicking off the red squigglies

[swift crag]

the editor forgor about every single type

VSCode does that to me occasionally

[rocky canyon]

Vector3 var1 = Vector3.zero;
float var2 = 0f;

public static bool TestOverlap()```

hehe, w8 that wouldnt make them error

[swift crag]

there's no reason to declare them outside of the function

[rocky canyon]

yea lol idk im just hunting for error (if there is one)

[glass urchin]

when I go to assign it to the output of TestOverlap it says it doesnt exist in the current context

[swift crag]

you're going to continue seeing a huge pile of errors because of this IDE problem

[rocky canyon]

why would bool be underlined?

yea.. the IDE is drunk

[glass urchin]

I mean in Unity

Unity says it doesnt exist

[swift crag]

where is TestOverlap defined?

if it's not defined in the same class, that won't work

[glass urchin]

in the same class

[swift crag]

Show me the entire script.

[rocky canyon]

can u share the entire class

yea, context would help

[swift crag]

I need to actually see what you're doing.

I opened the script from unity and restarted vscode

idk what else you could mean

[swift crag]

Do you not understand what this means?

try regenerating project files from the External Tools menu

[swift crag]

Yes.

In Unity.

You had to go to that menu when setting up VSCode to work with Unity.

[rocky canyon]

https://pastebin.com/n0G36Z70

heres some formatting

[glass urchin]

I did I think

[swift crag]

the errors don't say this #💻┃code-beginner message

[swift crag]

the errors say that you might have not assigned anything to trigger and trigger1

the variables absolutely exist

It's just possible for your code to not set anything

You could initialize both to null

[swift crag]

this is ancient unity

[glass urchin]

Unity 2017.4

[swift crag]

so it may be different

[rocky canyon]

lol facts

[swift crag]

I'm not sure if you can even get a working editor now

maybe with Visual Studio

[swift crag]

CapsuleCollider trigger;

if (foo) {
  trigger = bar;
}

trigger may still be unassigned after this code runs

Hence the error.

[glass urchin]

oh well it will be

[swift crag]

doesn't matter. the compiler is not convinced.

[rocky canyon]

i used chatgpt to reformat it.. it mentioned something may be wrong with trigger1 and trigger

[glass urchin]

screw the compiler

[swift crag]

If you're certain that a collider will be found, then initialize the variables to null

[glass urchin]

null check incoming

[swift crag]

no, this has nothing to do with checking for null

[glass urchin]

why?

[swift crag]

CapsuleCollider trigger;

This variable is not initialized.

[rocky canyon]

lol ya thats what chatgpt said 😄

[swift crag]

It doesn't contain null. It has no meaningful value at all.

[rocky canyon]

"here i added some null checks for you"

[swift crag]

Attempting to read trigger is an error.

[shrewd swift]

Damn for once its useful 🦐

[glass urchin]

cool compiler is happy

[swift crag]

well, this isn't about null checking

[rocky canyon]

well im not sure.. see ^

[swift crag]

it would be worthwhile to test if they're null right before you use them

[rocky canyon]

thats why i didnt post the changed code.. i just wanted it to reformat (i know it does that decent)

[swift crag]

but that's not why the compiler is mad

[glass urchin]

andddd debug printed nothing

[rocky canyon]

unreachable perhaps

[shrewd swift]

Does it print if null ?

Try printing (yourObject == null)

Unity doesnt print by default all stuff from my experiences

[gaunt ice]

Transform transform1 = webpieces[j].transform;
CapsuleCollider[] colliders1 = transform.GetComponents<CapsuleCollider>();
```no idea why you get colliders on same tf again

[rocky canyon]

u dont use Print() do ya?

[glass urchin]

Debug.Log

[rocky canyon]

i was askin Fishy, but ya Debug > Print

[glass urchin]

I used the wrong method

getcomponents not getcomponentsinchildren

so should I cache each set that intersects? can you make an array that contains arrays?

[rocky canyon]

why not make a struct or a class that contains w/e u need and just keep an array of those instead?

[glass urchin]

struct?

[rocky canyon]

sounds like ur trying to complicate it even more..
struct.. like a data holder

[glass urchin]

I think I did that in UE4 once but it was visual coding

[shrewd swift]

No debug.log
I didnt check if print does exactly the same

[glass urchin]

I wanna do it all in the Start method with not too much complex stuff

[rocky canyon]

public struct MyData
{
    public int intValue;
    public float floatValue;
    public string stringValue;
}```

[glass urchin]

a struct can contain arrays?

[rocky canyon]

but since u probably wanna store colliders/ and stuff like that may jsut make a class

[wintry quarry]

why not?

[glass urchin]

The script is a class.

I have a script on each game object that I'm trying to connect

[shrewd swift]

Sometimes idk if i should make a class or struct

They have a lot of similarities

[wintry quarry]

as a beginner you're probably better off using a class almost always

[rocky canyon]

public class MyData
{
    public Collider collider1;
    public Collider collider2;
}```
```cs
  // Create an instance of MyData
  MyData myDataInstance = new MyData();

myDataInstance.collider1 = blabla; myDataInstance.collider2 = blabla;

something along these lines.. u should get the idea

[shrewd swift]

Is there a good documentation where i could see the most differences

I have the reflex to always do structs

[rocky canyon]

the way i see it is.. if i want to use Unity stuff (the components) i use a class

[shrewd swift]

Im probably shooting myslelf in my toes

[rocky canyon]

if its just data.. like numbers only id use a struct

[wintry quarry]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/value-types
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/reference-types

[rocky canyon]

but thats just my personal workflow

[glass urchin]

then I can make an array of MyData structs?

[shrewd swift]

Yes

Maybe a list here if its changing at runtime

[rocky canyon]

since ull be adding to it u may want to use a List<> vs an Array

[wintry quarry]

of course

[glass urchin]

List?

[rocky canyon]

its just a class.. same as u make a list of any other class..

    List<MyData> myDataList = new List<MyData>();```

[glass urchin]

List<MyData>?

[rocky canyon]

well <NameOfScript>

so if u had a class called ColliderData it'd be List<ColliderData>

but since my example was of MyData i just used that

[glass urchin]

can I declare it inside my current class?

or at least in the same script?

[rocky canyon]

• Setup a class that holds the data you want

• When you want to add that to the list you create a new one
  MyData myDataInstance = new MyData();

• then you can set the values..
  myDataInstance.collider1 = whatever;

and then you add that to the list
myDataList.Add(myDataInstance);

[rocky canyon]

i think you can.. but im not 💯

[swift crag]

Sure. That's a nested type.

public class SomeClass {
  public class AnotherClass {
    public int x;
  }
}

inside SomeClass, you can refer to AnotherClass directly

[rocky canyon]

^ so now im 100

[swift crag]

Outside of SomeClass, you refer to it as SomeClass.AnotherClass

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/nested-types

It's useful for classes that are strongly associated with the containing type

for example, I have several "pickers" that use a set of criteria to decide what to do

each one declares a Criteria struct inside of it

although this is actually a no-no according to microsoft; they want nested classes to be private

too bad, Redmond! i'm doing it anyway!

[glass urchin]

can a method call itself?

[swift crag]

sure

[rocky canyon]

no..

[swift crag]

that's called recursion

[rocky canyon]

lol i mean.. it can

but then u get a infinite loop

[swift crag]

recursion can elegantly solve some problems, but you're also responsible for preventing infinite recursion

[glass urchin]

I just want to call it 4 times to get the 4 collider checks then once I have 4 to return

[rocky canyon]

oh then as long as u stop it thats fine

[glass urchin]

or once I've exhausted the list

[swift crag]

why would a method need to call itself for that?

sounds like method A should be calling method B

[rocky canyon]

ya, a for loop or foreach loop can do that

[glass urchin]

because I don't want to look at 4 nested for loops

[rocky canyon]

at this point i think you're trying to make ur setup as complicated as possible

Colliders check within itself, an array of an array, and now a recursive method..

[warm condor]

hey, can anyone tell me why when I press shift and "D" or "A" at the same time, I start at maxRunningSpeed? I there maybe a problem with the if statment?

        accilerate(direction);
        limitMaxRunningSpeed(direction);
        playerAnimator.SetBool("hasStopedRunning", false);
    }
    private void accilerate(int direction){
        if (Input.GetKey(KeyCode.LeftShift) ){
            initialiseAccelirationRunningValues(direction);
            accelerateBeforeRunning(direction);
        }
    }
    private void initialiseAccelirationRunningValues(int direction){
        if (Input.GetKeyDown(KeyCode.LeftShift)){
            speedDuringRunning = Math.Max(initialHorizontalSpeed, walkingSpeed);
            time = timeItTakesToFinnishAcceliration;
        }
    }

    private void accelerateBeforeRunning(int direction){
        if (time > 0f && speedDuringRunning < maxRunningSpeed){
            time -= Time.deltaTime;
            speedDuringRunning += accelirationValue * Time.deltaTime;
            rb.velocity = new Vector2(direction * speedDuringRunning, rb.velocity.y);
        }
    }
    private void limitMaxRunningSpeed(int direction){
        if (speedDuringRunning >= maxRunningSpeed){
            rb.velocity = new Vector2(direction * maxRunningSpeed, rb.velocity.y);
        }
    }```

[rocky canyon]

🤣 got me tripping over here

[rancid tinsel]

is there a simple way to make a 2D object face another 2D object?

i tried doing LookAt with a vector3 z = 0 but it just makes it disappear

[wintry quarry]

you would need to show your full script.

Use a paste site

[warm condor]

what site?

[wintry quarry]

Vector3 direction = targetPosition - transform.position;
direction.z = 0;
transform.right = direction;```
If your sprite uses "up" as forward then do `transform.up = direction;` instead

[wintry quarry]

[warm condor]

ok here you go https://hastebin.com/share/iyefosumeg.csharp

hope this works

[rocky canyon]

it probably faces the front part of the object towards the other one.. making it sideways.. so u cant see it b/c it has no thickness

[rancid tinsel]

yeah that might have been it

[rocky canyon]

mmhm but use praets method

its a solid way to get the direction

[rancid tinsel]

i know in general its bad practice to use LookAt in 2D

i was just hoping it would work but the solution was so simple literally just transform.up = target.position - transform.position;

[rocky canyon]

well transform.up or transform.right

make sure u use the right one 👍

[rancid tinsel]

.up in my case since its an arrow pointing upwards 🙂

[rocky canyon]

cool 👍

visual

[vale bronze]

how do I make a gameobject rotate towards my mouse to always be pointing at it? i've tried like 10 different things but no code works as I want it to.

[wintry quarry]

I can't help but think this is very overcomplicated

there's a lot of code here, I looked for a little but can't identify the problem, there are a ton of very long named functions here.

[warm condor]

yea sorry about that 😅

but Ik that the problem lies in the code that I just sent #💻┃code-beginner message

[glass urchin]

can i instance a list as null and still add to it?

[wintry quarry]

"instance a list as null" is an oxymoron

if you instantiated the list, it's not null

you can make an empty list, yes.

[warm condor]

wait @wintry quarry, could it be because because limitMaxRunningSpeed() is being called imidiatly instead of starting with the accilerate function?

[wintry quarry]

List<Whatever> myList = new();```

[swift crag]

two pieces of the puzzle:

• use Quaternion.LookRotation to get a rotation that faces a certain direction
• use Quaternion.RotateTowards to steadily rotate from one rotation to another

Is this a 2D game?

[wintry quarry]

I don't know and if it were up to me I would probably rewrite this from scratch. I have a feeling you can get most of this same behavior with about 15-20 total lines of code.

[vale bronze]

nevermind, Camera.main wasn't working because I had a script called Camera...

[swift crag]

woops

[warm condor]

oh alr

[swift crag]

common error

[swift crag]

(in 2D, you might use Quaternion.FromToRotation instead)

since you don't want to rotate an object's forward vector to face something

in 2D, the forward vector points into the screen

[smoky niche]

Hey there, is it possible to add two LayerMasks at once when doing Raycasting.
I have 2 LayerMasks which should both be detected by the ray, but apart from these rays, the LayerMasks don't have anything in common and I wouldn't want to make a separate LayerMask for them if not needed

[swift crag]

You can use | to union two layermasks together

| is the bitwise OR operator.

[wintry quarry]

One mask can contain any number of layers.

you cannot use two separate masks

[glass urchin]

SetOfColliders set;
set.collider1 = trigger1;
set.collider2 = trigger2;
set.collider3 = trigger3;
set.collider4 = trigger4;
ListOfSetsOfColliders.Add(set);

[wintry quarry]

just use one mask that contains both layers

public LayerMask myMask; < add both layers in the inspector

[rocky canyon]

looks good to me..

[wintry quarry]

what

[smoky niche]

What about this then?

Does that not work?

[rocky canyon]

ur making a new class
adding ur colliders to it.. and then adding it to ur list

[wintry quarry]

It works but seems like extra work/overcomplicated for the simple thing you want to do.

[smoky niche]

Awesome, thanks!

[rocky canyon]

not sure exactually.. what happens when you run that code a 2nd time? its gonna have the same name as the last time u made that class

you'll have (2) sets

[glass urchin]

i dont get it

doesnt it change set each time and add a new one?

[rocky canyon]

no.. when it runs the 2nd time.. its gonna set.collider1 =

its gonna overwrite what ur set already had

[glass urchin]

im completely confused

overwrite the set in the list or just the set?

[rocky canyon]

set.collider1 = <--- thats gonna set collider1 in teh class u have named set

[glass urchin]

It's .Add so doesn't it always prevent overwrite?

[rocky canyon]

when u run it again.. its gonna set collider1 in the class u have named set

same class... same name..

[glass urchin]

the class name is SetOfColliders

[rocky canyon]

it's gonna overwrite it

yea.. but ur using an instance of that class called set

[glass urchin]

uh huh

[rocky canyon]

u called it set

[glass urchin]

yes

[rocky canyon]

ya,,, so next time ur gonnna be using the same reference

do u not need different versions?

that code is gonna set the same colliders on the same set

over and over

each time u run it

[glass urchin]

no because

[rocky canyon]

ya, its gonna say "remember set?"

[glass urchin]

my for loops are indexed with i, j, k, and l

they are nested

[rocky canyon]

"yea change the variable of that again`

[glass urchin]

listen

[rocky canyon]

        SetOfColliders set = new SetOfColliders();
        set.collider1 = collider1;
        set.collider2 = collider2;
        set.collider3 = collider3;
        set.collider4 = collider4;

        listOfSetsOfColliders.Add(set);```

[glass urchin]

they are nested, and j starts at i+1, etc.

[rocky canyon]

i get that..

[glass urchin]

so each for loop only checks higher value indices

[rocky canyon]

but its still calling set.collider1 = thast always the same variable

ok, maybe i dont understand, ignore me then lol

[rocky canyon]

okay, that may be fine.. i thought u were calling a function multiple times

but its all in start

[jovial sandal]

Does some1 have any idea how i can make the shotgun from knockback like karlson

[wintry quarry]

Add a force to your player object (assuming it's a Rigidbody)

[rocky canyon]

ur shotgun should face a certain direction.. if u negate that direction (-direction) u get the opposite direction

then u can apply that to the player

-shotgunsTransform.forward; <-- the opposite direction

[jovial sandal]

Okey what if i am using a charcter controller

[rocky canyon]

then u got to add taht force into ur Move() function

[wintry quarry]

then you'll have to build the concept of external forces into the physics of the controller script yourself

[jovial sandal]

Can i use this?

[rocky canyon]

add it to ur vectors or w/e

[wintry quarry]

you can of course use that to get the direction but the actual handling of adding a force to the player will need to be written from scratch

and your movement code will need to be aware of it

basically you'll need to have an internal concept of velocity and forces in your player controller.

[shell herald]

two questions. i cant seem to hide my cursor. in the unity docs it states that a simple

Cursor.visible = false;

should do the trick, but for me, the visible doesnt seem to exist

also, in the new input system, if i use Any Key [Keyboard]that includes the esc key right? what do i need to do in order to exclude it?

[rocky canyon]

it really is that simple..

[glass urchin]

oh in game

[rocky canyon]

if its set to false.. when u click into the game window it should vanish

and u can test if its the escape key

[shell herald]

maybe im massively misunderstanding something, but this doesnt seem to work. atleast i get an error in VS and inside unity

[rocky canyon]

if (Input.anyKeyDown && !Input.GetKeyDown(KeyCode.Escape))

[languid spire]

visible

[rocky canyon]

well.. its not spelled right 😄

[shell herald]

even if it is

[languid spire]

do you have your own class/struct called Cursor?

[shell herald]

that might be it

[rocky canyon]

or rename ur Cursor to something more "custom" CustomCursor.cs maybe

don't forget to rename the class name inside the script also..

[shell herald]

yeah i simply changed the class since it was a non used script anyway

[rocky canyon]

did u see the way to check for escape key?

[echo matrix]

hey, is there a way to transform the postion of an object only on one axis and leave the other 2 as they are?

[frosty hound]

Yes, just use the same position on those axes when supplying the new vector

[echo matrix]

problem is my game object is moving

i currently have a transform.postition moving it at a set speed to the right

now i want to have a public float giving it its hight while moving (instantly)

[frosty hound]

So set the value of its position to the height you want

[honest haven]

    {
        //recheck in future what player can move does
        if (_canPickUp && Input.GetKey(KeyCode.P))
        {
            if (_isWeapon)
            {
                GameManager.instance.AddWeapon(GetComponent<Item>().itemName);
            }
        }
    }```best way to only register this once?

[wintry quarry]

Vector3 pos = transform.position;
pos.y = whatever;
transform.position = pos;
``` exactly as Osteel said.

[rocky canyon]

transform.position.x, transform.position.y, myposition.z;

or w/e

[robust kelp]

void OnGUI()
{
float rotatero = orientation.rotation.y;
GUI.Box(new Rect(10, 10, 140, 100), "Measurements");

    GUI.Label(new Rect(20, 40, 80, 20), "   " + rotatero + " m/s");
}

why is the first value so different than the other

[wintry quarry]

Use GetKeyDown

[honest haven]

thanks

[echo matrix]

ah so i was wondering how to tell it only the y axis... thank you @wintry quarry@frosty hound i will try pos.y

[wintry quarry]

rotation.y is one of four components of a Quaternion. You should under no circumstances be looking at the internal components of a quaternion unless you know what you're doing, which you don't.

it has nothing to do with the y rotation in the inspector.

[timber tide]

sceneView = SceneView.lastActiveSceneView;

what callback can I throw this in so it doesn't throw me errors after script compilation

OnSerializationCallback almost works after it spams my console with 999 errors

[grizzled pagoda]

hi i have a unity project due tuesday and im almost done, im having a problem getting the amount of an object in my scene at once then using that int in an if

[robust kelp]

true 😭 do you maybe know how to get that Y rotation 1 to 1?

[rocky canyon]

        // Find all active objects of type SomeType in the scene
        SomeType[] foundObjects = FindObjectsOfType<SomeType>();```

[grizzled pagoda]

am i allowed to post my code here so someone can give suggestions?

[rocky canyon]

use a Component <ScriptOfYourChoosing>

[grizzled pagoda]

zombiePrefabCount = FindObjectsOfType<ZombiePrefab>().Length;
Debug.Log("Number of ZombiePrefabs: " + ZombiePrefabCount);
if(ZombiePrefabCount == 0){
SpawnZombiePrefabWave1();

this is what i have rn

[rocky canyon]

that will place ALL of em in the array.. then u can use array.Length to get teh number of elements in teh array

yea, that basically what i was saying

[wintry quarry]

What are you actually trying to do here

[grizzled pagoda]

doesnt work though i keep getting this wierd error

[rocky canyon]

is this the name of the script?

u named a script ZombiePrefab ?

[grizzled pagoda]

name of my prefab i want to find the amount of

[rocky canyon]

yea no thats not what that does

[wintry quarry]

Are you looking for orientation.localEulerAngles.y;?

[grizzled pagoda]

oh

[rocky canyon]

it finds Components..

not names

[grizzled pagoda]

ah

[robust kelp]

check in which direction is the player rotating

[grizzled pagoda]

so i should use a script only found in my zombie prefabs as a reference?

[robust kelp]

maybe i have no idea what it does

[rocky canyon]

make an empty script put it on ur zombie.. and then search for that script

ya that will work

[grizzled pagoda]

alr ill try that

[wintry quarry]

Gets you the y component of the euler angle representation of the object's local rotation

which is what's displayed in the inspector

[rocky canyon]

plus even if it did work that way im pretty sure Unity adds Clone(1) Clone(2) and so on to ur prefabs

[grizzled pagoda]

oh

[rocky canyon]

even if the name was Originally ZombiePrefab it wouldnt find them correctly unless u manually rename them after u instantiated it

but u should be good if u have a component thats exclusive to the zombie

[grizzled pagoda]

okay

[shell herald]

on enable gets called every time the gameobject its on get activated right?

[grizzled pagoda]

rror while saving Prefab: 'Assets/My things/Prefabs/ZombiePrefab.prefab'. You are trying to save a Prefab that contains the script '', which does not derive from MonoBehaviour. This is not allowed.
Please change the script to derive from MonoBehaviour or remove it from the GameObject 'ZombiePrefab'.
UnityEditor.PrefabImporterEditor:OnDestroy ()

whats this mean?

i tried adding that blank script

[rocky canyon]

well it cant be completely blank lol

[wintry quarry]

yes or when the script itself is enabled

[rocky canyon]

using UnityEngine;
public class ImAZombie : MonoBehaviour
{

}```

[wintry quarry]

there's some script attached to the object that doesn't derive from MonoBehaviour. It used to but you removed : MonoBehaviour from it

@rocky canyon thanks dude your a lifesaver, for some reason all the documentation forums didnt specify you had to put a script in and i assumed it was an object that you had to find

also is there a way i can check for all objects in a array? or would it be simpler to check for all those that have the same script?

oh

i was looking at smth else then

[rocky canyon]

type means alot of things, Monobehaviour is a type, Collider is a type, a rigidbody is a type

a name is not however

[rocky canyon]

np, glad u got it fixed 👍

[glass urchin]

Type T?

[woeful lagoon]

Hey guys, the ui buttons I have (TMP) don't show up in builds but do in game view on the editor, I've searched the net and nothing came up that could fix my issue, any ideas?

[rocky canyon]

i was talkin to Mahdboi, but yea sometimes Type is represented as T

i think that means it can be any type or its a placeholder type

not so sure on that one

[rocky canyon]

i bet they do, but they're off the screen somewhere..

i would think ur canvas isnt scaling correctly.. and when u build (and its a bigger resolution) they're off the edge

[woeful lagoon]

Change scale mode to scale w/ screen size?

[swift crag]

your anchors are probably wrong

show me the inspector for one of your UI buttons

along with the scene view

[swift crag]

the anchor looks okay, but that's a really funnily shaped canvas

is your game view really a narrow rectangle?

[woeful lagoon]

Yeah

[swift crag]

also, depending on scaling settings, it's possible that the buttons are becoming very small and then winding up off screen

i wouldn't expect it, but...

consider changing the Pivot point to [1, 1] and then making Pos X and Pos Y both zero

[sage mirage]

Hey, guys! I have a question. Is there a way to make an animation for my Game Title Scene? I want to make something like when the game starts and the player appears in title scene where the name of the game is shown to see an animation like in background.

[woeful lagoon]

is that of my empty contaning them or the buttons themselvs?

Changing all of them worked

Thanks guys!

[rocky canyon]

i dont see why not.. ur game scene doesn't have to be ur generic 2d panel..

it can be a 3d world. with a text canvas on top for the buttons

[minor spindle]

Any settings suggestion for making transitions from idle states to walking etc faster?

Video so u can see what my issue is=

[rocky canyon]

u can manually drag that blue highlight or u can set this value that says "Transition Duration"

[minor spindle]

Tried that but the gliding still occurs :/

[rocky canyon]

not a coding question tho, if u have any more trouble with the animator, use #🏃┃animation or #💻┃unity-talk

[minor spindle]

Should I repost there or can we finish resolving it here?

[wintry quarry]

Uncheck "Has exit time"

or reduce the exit time

[minor spindle]

You're beautiful

[minor spindle]

thank you boss 🙏🏼

[rocky canyon]

ahh, ya i didnt see that. exit time means the animation plays fully before it would transition

[honest haven]

Hi trying to fix an issue. when my player walks over an object he slighty comes of the ground then walks in the air. Im trying to add gravity but now when he hits the object he starts flying into the air

https://gdl.space/tesakomimo.cs

[minor spindle]

So in theory only the melee and kick animations should have exit time if I understand correctly?

[rocky canyon]

if u want it to play fully yea,

[minor spindle]

Okay, thanks yall :))

[rocky canyon]

the ones w/o are ones that would get cut off

like walking, idling etc

[minor spindle]

Thank you 🙏🏼 I'll make sure to post animation related questions in #🏃┃animation next time

[rocky canyon]

no worries, if ur controlling animators thru code and thats the issue's then here is fine even for animations.. but if its in the inspector, and dealing with teh animator and stuff then animation is the place 👍

[minor spindle]

Gotcha :)), well u might see me here soon then cause my animation controller's code is messy as hell ☠️

[rocky canyon]

😱

[minor spindle]

but it works for now which is all that matters right 😅

[rocky canyon]

thats right!

[minor spindle]

"If it works it works"

[rocky canyon]

well, for now.. as u get better and learn more, you'll get into the refactor this and that.. and start thinking about scaleability (how easy is it to add or modify this).. and so on

Hey, I feel like this is a silly question, but I literally cannot get the bullet I am firing to instantiate vertically, I tried fixing it manually in the animator., I tried rotating the prefab itself, but nothing it working. The code is here

using System;
using UnityEngine;
using UnityEngine.InputSystem;

public class Shooting : MonoBehaviour
{
    public Transform firePoint;
    public GameObject bulletPrefab;
    public float bulletForce = 20f;

    [SerializeField] private InputActionReference shootAction;

    public event Action OnShoot; // Event to handle shooting

    private void OnEnable()
    {
        shootAction.action.Enable();
        shootAction.action.performed += OnFirePerformed;
    }

    private void OnDisable()
    {
        shootAction.action.Disable();
        shootAction.action.performed -= OnFirePerformed;
    }

    private void OnFirePerformed(InputAction.CallbackContext context)
    {
        if (bulletPrefab != null)
        {
            Shoot();
        }
    }

    void Shoot()
    {
        Debug.Log("Bullet fired");
        GameObject bullet = Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
        Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
        rb.AddForce(firePoint.up * bulletForce, ForceMode2D.Impulse);

        // Invoke the OnShoot event when shooting.
        OnShoot?.Invoke();
    }
}```

Ok thanks haha

I tried Control, but it was a bit confusing honestly

[rocky canyon]

i use 'Fork' but beginner may see more documentation with GitDesktop or w/e its called

[wispy karma]

Prefab is verticle too

it's weird af

[rocky canyon]

well github isn't a walk in the park

[wispy karma]

Fork is really good I hear

How do you like it?

[rocky canyon]

but if u start it correctly it shouldnt be too bad

[rocky canyon]

its the only software ill use from now on

unless something about it changes

[wispy karma]

oh fr?

[swift crag]

ride or die on the command line

[wispy karma]

Doesn't it cost money tho?

[swift crag]

Lots of things cost money

[wispy karma]

True

[swift crag]

it's good to pay money for things you use a lot

[rocky canyon]

i love the visual filetree

[swift crag]

rebases your repository into a single commit

"add files"

[north kiln]

Fork 🍴 is da best

[shrewd swift]

What is Fork ?

[swift crag]

okay, so @cunning locust : generics let you write methods that work on many different types

[shrewd swift]

A repo & version control manager ?

[swift crag]

have a look at https://learn.unity.com/tutorial/generics?uv=2019.3&projectId=5c88f2c1edbc2a001f873ea5

[north kiln]

https://fork.dev

it's a git GUI

[woeful lagoon]

Having a bit of trouble with netcode D; , my clients aint moving

[languid spire]

@cunning locust

T math<T>(T a, T b, char opr = '+') where T: struct

[woeful lagoon]

I have the clientnettransform script from git

[shrewd swift]

Looks intersting, the one time price seems honest to me

[rocky canyon]

public abstract class Singleton<T> : MonoBehaviour
where T : MonoBehaviour
{
    public static T Instance { get; private set; }

    void Awake()
    {
        // Destroy this object if we already have a Singleton defined
        if(Instance != null)
        {
            Destroy(gameObject);
            return;
        }
        DontDestroyOnLoad(gameObject);
        Instance = (T)this;
        DoAwake();
    }

    // Virtual method to allow implementations to use Awake
    protected virtual void DoAwake() { }
}``` oh, i have a generic singleton

using UnityEngine;
public class GameManager: Singleton<GameManager>
{
    public void Start()
    {
        Debug.Log("Check");
    }
}```

i think some of its wrong tho.. I can't remember if i ever fixed it

[cunning locust]

Interesting.. this is overly complicated for it's purpose

[shrewd swift]

A singleton i just a class that will be used once ?

[rocky canyon]

ya, pretty much

can only be 1

of itself

so u can have a reference u can access via anywhere, knowing its the only one

[swift crag]

doing math with this signature is pretty awkward

[rocky canyon]

singleton.Instance.DoStuffFromAnywhere();

[wintry quarry]

It means there will only be one instance in some scope. By scope I mean "one instance per scene" or "one instance per application" etc..

[swift crag]

given that struct makes no promises about being to add the values, and that the compiler doesn't think you can cast back from int to T

[languid spire]

True, but it makes a great generic compaprer

[woeful lagoon]

How do I give ownership of a player object to a client so they can use transforms on them

[rocky canyon]

how could u cast to T?

hows that work in general speaking

[shrewd swift]

So my player class will be a singleton since its a solo game

[wintry quarry]

You can make it one, if you wish

[languid spire]

just (T)

[swift crag]

the compiler will at least accept doing if (result is T castedResult); no idea if it would work

[wintry quarry]

both of those work, as well as as

[swift crag]

it doesn't accept casting an int to T with a cast operator

[rocky canyon]

? u would have each player client running code when their instance is theirself

[rocky canyon]

and then anything could cast it back?

[languid spire]

yep

[rocky canyon]

🤯 ... welp, thats interesting

[woeful lagoon]

My clients only get their camera input and noi transforms

[swift crag]

the gist of generics is that you declare a method that has one or more unspecified types. So:

public T Identity<T>(T input) {
  return input;
}

This method may be used with any type.

int x = Identity(3);
float y = Identity(1.0f);
string z = Identity("hello");

However, this method is not very useful. We have absolutely no constraints on what T can do, so we can assume very little about it

[languid spire]

the call would be

int x = math<int>(x,y,'*')
or
float z = math<float>(a,b,'-')

so no casting required

[swift crag]

the method body is working with T, however

[north kiln]

you know what would explain this, watching a tutorial 😛

[languid spire]

yes, exactly what you want

[rocky canyon]

well then u gotta send those RPC things back and forth to modify the transforms i reckon (i know nothing about multiplayer) lol i dont know how ur multiplayer setup is either (what u mean they only get their camera?) and how is they? : aka someone else would have to help :

[swift crag]

and the compiler doesn't believe that casting an integer value to T works at all

[woeful lagoon]

Clients have the ability to modify the camera and such but can't move

[rocky canyon]

then why not let them the ability to modify transforms?

[languid spire]

no it wont bacause you cannot constrain T to primitives only value types

[woeful lagoon]

I don't currently have any idea on how to do that

[cunning locust]

wait wait wait, you wrote public T, so the why is the function called Identity, not T

[rocky canyon]

how did u do the camera?

[swift crag]

why is public float GetNumber() { return 3.5f; } not called float?

[woeful lagoon]

Using a public transform

With movement its applying force to a rb

Camera is locked to a var

[cunning locust]

oh i see it now lol

[rocky canyon]

u have to write player code, one that all players would use to move their respective transforms

[swift crag]

T is the return type of the method. The method takes a single parameter of type T and returns something of type T.

[cunning locust]

makes sense

[swift crag]

Go through this tutorial. Feel free to ask if you have questions afterwards https://learn.unity.com/tutorial/generics?uv=2019.3&projectId=5c88f2c1edbc2a001f873ea5

[languid spire]

and you need to constrain T in order to be able to do anything sensible with it

[swift crag]

indeed!

the more you constrain it, the more you can do with it

completely unconstrained types are only really found in data structures

[woeful lagoon]

 // calculate movement direction
 moveDirection = orientation.forward * verticalInput + orientation.right * horizontalInput;

 // on ground
 if (grounded)
     rb.AddForce(moveDirection.normalized * moveSpeed * 10f, ForceMode.Force);

 // in air
 else if (!grounded)
     rb.AddForce(moveDirection.normalized * moveSpeed * 10f * airMultiplier, ForceMode.Force);```

[swift crag]

and even then, they often make some demands of the type -- such as making sure that it's comparable

[woeful lagoon]

This wouldn't work?

[cunning locust]

I'll save this for later, right now im watching some 10 hours beginner tutorials on c# itself

thanks!

[rocky canyon]

do bolf 😈 🖥️ 🖥️ .. lol

[woeful lagoon]

whuh

aight

[swift crag]

If you're using a regular Rigidbody, then every client will be trying to simulate each other's rigidbodies

[woeful lagoon]

oooh

ok, I gotcha

[swift crag]

https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/physics/#networkrigidbody sounds relevant here

[cunning locust]

Unity on 1 monitor, visual studio on second, tutorial on third, if i had a forth one, i'd use it for c# manual lol

[swift crag]

Been a hot minute since I played with this stuff, though

[woeful lagoon]

I already have a network rb tho

[rocky canyon]

whats controlling it?

[woeful lagoon]

wdym

Aight fixed

my movment is scuffed now tho

only on the client apparently

[rocky canyon]

        if(Input.GetMouseButtonUp(0) && (drag ^ hold))
        {
            if(hold) hold = false;
            if(drag) drag = false;
        }```
does this make sense?

i mean, both hold and drag need to be the same value, also

[north kiln]

why not just write something normal lol

[rocky canyon]

lol, i seen a mention of a ^

and if i think im right thats an exclusive or gate?

so either one or the other returns true for the entire ()

lol, i was refactoring b/c it was worse, i have 3 or so if conditionals looping at different times each also having the GetUp tagged towards the bottom of the function

[north kiln]

what are you trying to check? Because it'll just check if they're different

[rocky canyon]

    void RequestSelection(Vector3 pos)
    {
        Ray ray = Camera.main.ScreenPointToRay(pos);
        RaycastHit hit;

        if(Physics.Raycast(ray,out hit,distanceOfRay))
        {
            focusedTransform = hit.transform;
            if(hit.collider.TryGetComponent(out ISelect selectable))
            {
                scrollLock = true; // the map shouldn't move until we release
                hold = true; // we're (possibly holding down the mouse button)

                lastSelectable = selectable;

                // Store the initial mouse position when the drag starts
                initialMousePosition = Input.mousePosition;
                drag = true;
            }
            else
            {
                Debug.Log("We clicked something unselectable");
                lastSelectable = null;
            }
        }
    }
``` mouse down starts a timer, to see if we clicked a ISelect interface

and then theres diff states, if its selected and we click and hold a 2nd menu opens.. if its selected and we click and drag a different function would trigger

and for the time being im ignoring stuff if its not selected if clicking and doing nething

i think that conditional works just fine tho, as ive not exposed the drag variable but it debugs..

[grizzled pagoda]

i have a zombie that continually moves forward and will encounter a plant that its supposed to collide with and eat, problem is it passes through the plant and reduces the plants health by one only and doesnt stop and reduce the plant's health past the first collision

[echo matrix]

 {
     float elapsed = 0;
     while (elapsed < duration)
     {
         amplitude = normalPWave.Evaluate(elapsed);
         elapsed += Time.deltaTime;
         yield return null;
     }
 }```

[glass urchin]

wait I know what the problem is

I have to modify the Vector3 not the float

[grizzled pagoda]

void OnCollisionEnter(Collision collision){
if(collision.gameObject.CompareTag("Pea")){
HealthPoints = HealthPoints - 1;
Debug.Log("Zombie HealthPoints: " + HealthPoints);
}
} this is what i h ave

[echo matrix]

{
    yPos = GameObject.FindWithTag("ECG").GetComponent<ECGPatern>().amplitude;
    transform.position += Vector3.right * moveSpeed * Time.deltaTime;
    Vector3 targetYPosition = transform.position;
    targetYPosition.y = yPos;
    transform.position = targetYPosition;
}```

is there anything wrong with the code that could produce this error only at the beginning?

[tawdry rock]

oncollisionenter runs once, if you want to run multipe times you can use oncollisonstay

[grizzled pagoda]

i switched it to stay but it still only runs once

[tawdry rock]

what you try to achive is not clear to me. so the zombie eat the pea and decrease the zombie health by 1 like in every seconds?

[glass urchin]

how to make a certain scripts start function happen before another's?

or generally order them?

[tawdry rock]

use awake, it starts before start function

[glass urchin]

but what if I have multiple I wanna order?

[tawdry rock]

Edit > Project Settings and then select the Script Execution Order

[glass urchin]

okay nice thanks

thats easy

[rancid tinsel]

why is this code resulting in the color changing back to startColor despite the mouse still hovering the object??

[grizzled pagoda]

what i have is this rn for the zombie, void OnCollisionStay(Collision collision){
if(collision.gameObject.CompareTag("Pea")){
HealthPoints = HealthPoints - 1;
Debug.Log("Zombie HealthPoints: " + HealthPoints);
}
if(collision.gameObject.CompareTag("Plant")){
speed = 0f;
}
else if(
speed = 10f;
)
} in the plant, i have a on trigger enter that reduces the plants health continously

void OnTriggerEnter(Collider other){
if (other.CompareTag("Zombie"))
{
PeashooterHealth--;
Debug.Log("PeashooterHealth: " + PeashooterHealth);
}

// Check health in OnTrigger
    if (PeashooterHealth <= 0)
    {
        Destroy(gameObject);
    }

[tawdry rock]

@grizzled pagoda please use alt+96 to make a ` and place your code in a code tag 3

[grizzled pagoda]

alr

alt 96?

[rocky canyon]

it shouldn't change back, try:
https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnMouseOver.html

[glass urchin]

hold alt and type 9, 6

that gives `

[tawdry rock]

do you have IPointerEnterHandler, IPointerExitHandler?

[rancid tinsel]

ill recorrd a clip to showcase the issue

[rancid tinsel]

no, no idea what those are

[rocky canyon]

even that might not work.. b/c it says

[grizzled pagoda]

test

[tawdry rock]

https://docs.unity3d.com/2017.4/Documentation/ScriptReference/EventSystems.IPointerEnterHandler.html

[grizzled pagoda]

i did that and it doesnt work

[glass urchin]

// c code here

do you have unicode installed?

[tawdry rock]

put it after monobehaviour then you can use public void OnPointerEnter(PointerEventData pointerEventData) or OnPointerExit @rancid tinsel

[grizzled pagoda]

unicode? on my pc or what

'test'

[rocky canyon]

as long as it has a collider it should work..

[glass urchin]

copy this message as a template

[north kiln]

The backtick is generally in the top left of the keyboard

[rocky canyon]

a graphic/physics raycaster may be needed on teh camera

i cant remember about that generally

[grizzled pagoda]

test

there we go

[rocky canyon]

but his issue was he said it changed back

[grizzled pagoda]

ah i see

[grizzled pagoda]

sorry for being dumb haha

[rocky canyon]

so that means it must have changed originally

[rancid tinsel]

the clip i just sent should demonstrate what I mean

[grizzled pagoda]

` void OnTriggerEnter(Collider other){
if (other.CompareTag("Zombie"))
{
PeashooterHealth--;
Debug.Log("PeashooterHealth: " + PeashooterHealth);
}

// Check health in OnTrigger
    if (PeashooterHealth <= 0)
    {
        Destroy(gameObject);
    }
}`

this is my plant code

[rancid tinsel]

startColor is when its grey, hoverColor is when its yellow

[grizzled pagoda]

continously reducing health of plant as it collides with a zombie

[glass urchin]

also alt codes dont work on the top row of numbers unless you have that enabled. but works on the keypad by default

[rocky canyon]

somethings in teh way @rancid tinsel

[north kiln]

Use 3 backticks not 1

[rancid tinsel]

nothing is there tho... surely not pixel perfect camera?

[grizzled pagoda]

        if(collision.gameObject.CompareTag("Pea")){
            HealthPoints = HealthPoints - 1;
            Debug.Log("Zombie HealthPoints: " + HealthPoints);
        }
        if(collision.gameObject.CompareTag("Plant")){
            speed = 0f;
        }
        else if{
            speed = 10f;
        }
    }```

[rancid tinsel]

yup its pixel perfect camera causing it

[tawdry rock]

you can add a component called event trigger that listen for your mouse but i would still stick to IPointerEnterHandler and IPointerExitHandler

[grizzled pagoda]

this is my zombie code, reducing health when it gets hit with a pea and staying in place till it stops colliding with a plant, but i think i may have to put this if for speed inside a collision stay right?

[rancid tinsel]

i mean if pixel perfect camera is somehow interfering with the mouse position then would that even help?

also a similar issue happens (not as badly as in the clip) when fully zoomed out

it seems to think the mouse isnt over the square anymore when close to the edges

• with pixel perfect camera disabled

[tawdry rock]

maybe your codes just overwrites it somewhere (in a update maybe) thats why you see yellow square for a frame

[rancid tinsel]

this is the entire code to do with those squares so I don't think so

could anyone tell me why this may not be working?

[calm coral]

The type or namespace name 'InputSystem' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)
Hey, I have a pretty basic problem not sure why using UnityEngine.InputSystem; doesn't work

[rancid tinsel]

might be better to use collision layers?

[grizzled pagoda]

why? and how would i set those up?

[tawdry rock]

you are destroying the gameobject ( the pea) if you want to destroy the zombie then Destroy(collision.gameObject);

[rancid tinsel]

if you go into Project Settings > Physics (or Physics 2D if youre in 2D)

[grizzled pagoda]

problem is i want to destroy the pea, it just passes through it instead

[rancid tinsel]

you can scroll all the way down to have the different layers and what they can collide with

[ivory bobcat]

Is it properly installed?

[grizzled pagoda]

okay

[rancid tinsel]

but youll have to make new layers by clicking on the pea and zombie objects, clicking layers and making new ones respectively

[calm coral]

I guess? I've changed to the new input system but still doesn't work

[grizzled pagoda]

what am i looking at?

[rancid tinsel]

the bottom bit with the tickboxes

[ivory bobcat]

It's likely not installed then..

[rancid tinsel]

but you should create layers first

[ivory bobcat]

The first sentence https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/QuickStartGuide.html

[grizzled pagoda]

how

[rancid tinsel]

go on your zombie prefab and click on the dropdown under its name in the inspector called "Layer"

and then Add Layer

name it and then go back to the zombie prefab and change the layer to that

do the same for the bullets and plants as well

[grizzled pagoda]

layer overides?

oh nvm add layer

[rancid tinsel]

but give them individual ones

[grizzled pagoda]

found it

[rancid tinsel]

nice

[calm coral]

Yeah, my bad, I forgot to install the package thought it's already built-in, thanks!

[rancid tinsel]

yeah its just easier to do it this way than checking which thing it colllided with

[grizzled pagoda]

okay

[rancid tinsel]

and hopefully you wont run into issues with this method

[grizzled pagoda]

what about sorting layers? that important or nah?

[rancid tinsel]

where is that?

[grizzled pagoda]

just beside the layer selection

[rancid tinsel]

oh in sprite renderer?

[grizzled pagoda]

also, if i want the zombie to interact with all my plants the same, ill just give the plants the same layer right?

[rancid tinsel]

yes

[grizzled pagoda]

okay

and coding wise how would i check if the layers collide?

[rancid tinsel]

basically what the ticks do is you choose which layer can collide with which layer

[rancid tinsel]

on collision enter

[glass urchin]

how do I see my code's memory usage and stuff while testing?

[rancid tinsel]

if your plants will only collide with the zombies, then you can just check for general collision

cuz it will be the only one that can happen

if you have 2 different layers colliding with a layer then you will have to check like normal i believe

[grizzled pagoda]

so instead of checking for tags i check for layer colliding or what?

[rancid tinsel]

no no

ok what will your plants collide with?

is it just the zombies?

[icy cape]

yo so where did they move navmesh stuff in 2022

[grizzled pagoda]

just zombies yeah

[icy cape]

because I don't have the window ai tab that im pretty sure my projhect is meant to

[rancid tinsel]

then you will untick everrything apart from zombies in the project settings

that means that only zombies can colllide with plants

[grizzled pagoda]

okay

[tawdry rock]

download it from package manager ( type AI in unity registry)

[rancid tinsel]

same as how i have bullets only colliding with enemies on mine

[grizzled pagoda]

i also want the pea to collide with the zombie, how would i do that?

[icy cape]

oh ok thanks

[glass urchin]

is 4096 rigidbodies a lot/too many?

what's a good limit?

[rancid tinsel]

same way, for the bullet or pea layer you would disable everything except zombies

basically tick means it can collide with objects in that layer, untick means it cant

[grizzled pagoda]

okay

[tawdry rock]

@rancid tinsel https://gdl.space/fowekolitu.cpp try this (uncomment what i commented)

[grizzled pagoda]

but my zombie cant even collide with the plant cuz theres no option to tick it you see?

[rancid tinsel]

that doesnt change colors at all, the only bit that still works is the commented bit :/

do you not need something else forr the pointer things to work?

[shrewd swift]

why do you need that many rb ?

[tawdry rock]

Mahdboi, are you making 2d or 3d game?

[grizzled pagoda]

3d

[rancid tinsel]

there is

look at the left side of the table

its a bit confusing to look at

but zombie is on both the top and the left

[grizzled pagoda]

ohhh

damn

[rancid tinsel]

yeah that got me earlier too lol

[grizzled pagoda]

aight fixed it

now how do i check for it

in my code

[rancid tinsel]

just normal OnCollisionEnter

[grizzled pagoda]

parameters stay the same?

[rancid tinsel]

so basically untick everything except the thing you want it to collide with

and it should work

[grizzled pagoda]

so like

[rancid tinsel]

OnCollisionEnter(Collision collision)

get rid of the if statement basically

[grizzled pagoda]

oh

[rancid tinsel]

and it should work fine

[tawdry rock]

strange, it works for me

maybe use image for your sprite and change the image's color

[rancid tinsel]

i mean the Sprite Renderer works for you no?

[grizzled pagoda]

i want the zombie to stay in place when it collides with a plant and reduce health when it gets hit by a pea, gimme a sec ill show you what i have

[rancid tinsel]

update on the issue: this only happens on certain squares, towards the edge of the screen mainly

[rancid tinsel]

use a bool for movement like moving = true

[rancid tinsel]

then make movement only happen when its true

[grizzled pagoda]

how would i specify which layer is colliding

[rancid tinsel]

oh for zombie you would need the pea and the plant layers

right

[grizzled pagoda]

is there no way i can specify each indivisually?

[rancid tinsel]

check the number of the layer for plants and peas

so where you select the layer it should have a number next to the name

[grizzled pagoda]

yeah

[rancid tinsel]

if (collision.gameObject.layer == plant layer number)

[grizzled pagoda]

ah

okay

[rancid tinsel]

let me know if that works

[tawdry rock]

@rancid tinsel see if this helps. put image component on your square, and put your sprite as the source. make a refference for the Image then change it's color by refferencename.color = startColor

[grizzled pagoda]

doesnt work at all

doesnt give me an error either

[rancid tinsel]

mahdboi wanna do a quick call so you can screen share it to me?

i want to see what the inspectors like

[grizzled pagoda]

alr cant talk rn tho

[rancid tinsel]

ill try that in a bit, might also be worth bringing it up with my professor on tuesday maybe he will know what the issue is

[rancid tinsel]

thats fine

[warm condor]

Is there a reason why this invoke function is not delaying the function enableMovingAndAnimationControles()?

        if (Input.GetKey(KeyCode.A) && Input.GetKey(KeyCode.D)){
            Invoke("enableMovingAndAnimationControles",2f);
        }
    }```

That is being called in the update function so I think that the problem is comming from this function right here.

can someone help me understand how this is possible? As soon as I take any damage my health percentage just goes to zero. I feel like i'm doing something stupid but it looks right to me!

        {
            float healthPercentage = characterData.CurrentHealth / characterData.MaxHealth;
            healthPercentage = healthPercentage * 50;
            int index = (int)healthPercentage - 1;
            Debug.Log("Cur Health: " + characterData.CurrentHealth + "\nMax Health: " + characterData.MaxHealth + "\nHealth Percentage: " + healthPercentage + "\nIndex: " + index);
            healthGlobe.GetComponent<Image>().sprite = healthGlobeImages[index];
        }

.98 * 50 should get me 49

Why do you multipe with 50?

[unkempt tree]

because I got 50 diff sprites* for my health globe

how can .98*50=0 though?

Hello! Was just wondering if anyone knew how to stop a player being able to change the trajectory of a jump while mid air

98/100 = 0, you have to cast at least one of them to float
