under default i was used to have compression set to normal quality

#

but in your inspector i can't see compression field

queen adder
#

yeah happens to the other sprites i use

queen adder
late bobcat
#

can you give me your sprite in dm?

#

i'll try wiht my unity

queen adder
#

ye

#

does discord compress it

late bobcat
#

it does i believe

#

see dms

hi i dont know what this errors means

If so, is it in a namespace?

timid hinge
#

forget it, thanks btw

grand sigil
#

what would be the cause where the TMP_Text i assigned at the editor is suddenly missing when i instantiated the gameobject which is a prefab?

polar acorn
#

Show !code

eternal falconBOT
grand sigil
polar acorn
#

Show the code

rocky canyon
#

is the prefab referencing a TMP element thats inside hte prefab? or is it in the scene?

grand sigil
grand sigil
#

I tried reassigning it in the prefab view

polar acorn
grand sigil
#

All TMP_Text

polar acorn
grand sigil
#

The first one

#

The parent GameObject appears but the childs it was supposed to come with are missing

polar acorn
grand sigil
#

Debate Manager?

polar acorn
grand sigil
#

ohh ic

polar acorn
#

Also, why is debDataHolderPrefab of type GameObject if literally the first thing you do is a GetComponent? Just make the variable of type DebaterHolder

grand sigil
grand sigil
#

i can see the instantiated gameobject with both variables appearing with the inputed text

polar acorn
grand sigil
#

Clicking on it even highlights it

polar acorn
# grand sigil

Okay, so, RoundXArea is set to itself, and the first thing you do in that function is destroy all children of RoundXArea

grand sigil
#

Ohh

polar acorn
#

So the reason it says all of those text components are missing is because they're missing

grand sigil
#

Im dumb

#

Thanks

I have this code from a package that i modfied:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Photon.VR;
using TMPro;

public class ColorScript : MonoBehaviour
{
    public TextMeshPro ColorText;
    public float Red;
    public float Blue;
    public float Green;
    float TrueRed;
    float TrueBlue;
    float TrueGreen;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        ColorText.text = string(Vector3(Red,Blue,Green));
        TrueRed = Red / 10;
        TrueBlue = Blue / 10;
        TrueGreen = Green / 10;

        Color myColour = new Color(TrueRed, TrueBlue, TrueGreen);
        PhotonVRManager.SetColour(myColour);
    }

}

But ColorText doesn't show in the inspector(idk how yall call it in unity godot)

grand sigil
#

Change TextMeshPro to TMP_Text?

languid spire
#

use TMP_Text not TextMestPro

polar acorn
languid spire
#

not at all sure where this syntax comes from

ColorText.text = string(Vector3(Red,Blue,Green));

yeah definitely looks like some compile errors

Instead of 'just trying the python way' try 'just reading the C# documentation'

Hello, these errors appear after installing game creator asset how to fix them?

image.png
wintry quarry
#

but also you can't construct things without new in C#

#

You can't just do Vector3(x, y, z)

#

you have to do new Vector3(x, y, z) or just new(x, y, z) if the type can be implied @stable moth

zenith cypress

#

that's a literal 🙂

#

for this particular example IDK why they want to use Vector3 though

Bump. Still having this issue, i'm going crazy. It seems like all the obstacles(cubes) are spawning on the inspector's position. If i debug the obstacles spawn position tho are all differents, but still spawning all on the same spot

zenith cypress
#

@wintry quarry is the new syntax for arrays a literal too? The var array = [1, 2, 3]; thing, never really thought about it. Is it just if you make an object without the new? I assume not because of constants or anything.

# late bobcat here

The object you're spawning wouldn't happen to have a CharacterController component on it, would it?

late bobcat
#

it was a bug

#

no it doesn't have a character controller, just a simple 3d cube with a rigidbody and box collider

#

here it is

echo aurora
#

so when i made a bullet shooting mechnaic and the spawn point i get weird duplication after shooting another bullet and I would like it to just be 1 click 1 bullet if that makes sense ```using UnityEngine;

public class BulletShooter : MonoBehaviour
{
public GameObject bulletPrefab; // Reference to the bullet prefab
public float bulletSpeed = 10f; // Speed of the bullet
public Vector3 spawnPointOffset = new Vector3(1, 0, 1); // Offset from the player position

private void Update()
{
    // Check if the left mouse button is clicked
    if (Input.GetMouseButtonDown(0))
    {
        ShootBullet();
    }
}

private void ShootBullet()
{
    // Calculate the bullet spawn position based on the player's position and rotation
    // Adjust the spawnPointOffset to move the spawn position to the right of the player and slightly forward (like holding a gun)
    Vector3 spawnPosition = transform.position + transform.right * spawnPointOffset.x + transform.forward * spawnPointOffset.z + transform.up * spawnPointOffset.y;

    // The rotation should match the player's rotation
    Quaternion spawnRotation = transform.rotation;

    // Instantiate a new bullet instance at the calculated spawn position and rotation
    // Instantiate a new bullet instance at the calculated spawn position and rotation

    GameObject bulletInstance = Instantiate(bulletPrefab, spawnPosition, spawnRotation);


    // Add this line at the end of ShootBullet() method
    Destroy(bulletInstance, 5f); // Destroys bullet after 5 seconds


    // Get the bullet's rigidbody component
    Rigidbody bulletRb = bulletInstance.GetComponent<Rigidbody>();

    // Log the instance ID of the bullet
    Debug.Log("Bullet Instance ID: " + bulletInstance.GetInstanceID());

    // Add force to the bullet in the direction of the spawn position's forward vector
    bulletRb.AddForce(transform.forward * bulletSpeed, ForceMode.Impulse);

    // Log the instance ID of the rigidbody to which the force was applied
    Debug.Log("Rigidbody Instance ID: " + bulletRb.GetInstanceID());
}

}
using UnityEngine;

public class Bullet : MonoBehaviour
{
private void OnCollisionEnter(Collision collision)
{
// Destroy only the bullet instance, not the prefab
Destroy(gameObject);
}
}``` I cant figure it out im gonna pull my hair out lol

How can i fix Vector3 showing things with 2 extra zeros ?

polar acorn

#

Hmm, ok, that took me a bit because the comments make it really hard to read. But it does look fine. You may want to set the RIGIDBODYs position instead of transform.position

#

Also, doubt this is even relevant, but in your random ranges, you don't need a + to make that value positive

Hmm. https://hatebin.com/ There is something wrong with raycast here. I have another script that handles prompt messages. in OnFocus and OnLoseFocus. When I move my mouse to and away from the interactable object. The raycast seem to be working. But when I move sideways for example while looking at the interactable object. The prompt message does not go away. It is as if im still looking at the interactable object. What may be causing it?

This here is what I am talking about if its any help

I log the OnLoseFocus. It does not work until I shake my camera around a bit.

I can give the Interactable script as well but it just inherits from an abstract Interactable class. and has OnFocus, OnLoseFocus and OnInteract thats all.

Well okay I fixed it. Thanks.

#

Hey, guys! I want to make a Game Mechanic for my game which is a flappy bird. So, I want to increase the speed gradually in order to make it difficult for the player. Can someone help me implementing that?

#

I don't know where to start and how to start basically

#

Never done that before

summer stump
#

Plug that in update

sage mirage
#

hmm let me try.

summer stump
#

Unless you want to increase it at checkpoints, which would be a bit different

sage mirage
#

Alright! I actually made that Game Mechanic but now the problem is that I can't actually synchronize the speed of each game objects I am spawning. I am spawning my game objects so my pipes actually with spawn rate using Enumerator. I got confused on that something happening and I can't sync their speeds. It only happening for my pipes which I have 3 different pipes as prefabs, I am also giving speed to my background and ground layers so they are fine.

#

I see my objects instances to spawn on different positions

#

When I am using enumerator and I have a fixed speed rate then it is fine

Oh ...

so either inherit from MonoBehaviour if this should be a component, or call StartCoroutine on some MonoBehaviour reference

rich adder
#

myMonobehaviorReference.StartCoroutine(whatever

swift sedge
#

you need to inherit from MonoBehaviour in any case

slender nymph
#

if it does not need to be attached to a gameobject as a component then it is not necessary to inherit from monobehaviour

Lots of methods that "feel" like magic globals are actually just UnityEngine.Object or UnityEngine.MonoBehaviour methods

no, that's the latest 2021 LTS

it's a major version number behind the current LTS, yes, but it's still actively maintained

#

it's also the only version that has access to those microgame templates

Putting the year in the version number definitely makes older LTS's seem "outdated"

hi, just a quick question about the use of readonly. What's the point of this property, is it used just for variable we don't want to modify in inspector ? thx

rich adder
#

unity 6k sounds futuristic

rich adder
slender nymph
swift sedge
slender nymph
#

so it's for when you want to keep the same instance of that object and never assign to again it within the containing object's lifetime

upbeat yacht
#

oooh ok ! very clear thank you very much

swift sedge
# 
readonly int num;

void SomeMethod()
{
    num = 1;
    num = 2; // error and won't assign
}
swift crag
#

that is incorrect; the only rule is that you cannot assign to it outside of a constructor or field initializer

#

you cannot assign to it in any other method

#

in this case, both lines would be errors

#

The constructor is unique in that it's guaranteed to run at most once at a very specific point in the object's lifecycle

#

along with field initializers

#

Nothing else has those guarantees.

swift sedge
#

so... would const work?

upbeat yacht
#

so i use readonly only if i'm sure to use my variable just once ?

slender nymph
#

no, you use readonly if you want to prevent assigning to the variable outside of the field initializer or constructor

polar acorn
#

If you never intend to change it

#

just read the value

rich adder
slender nymph
timber tide
#

readonly doesnt work that well with monos beyond anything you can initialize in the member scope space

#

there is some interfaces that can help with dynamic instantiations though

slender nymph
#

i pretty commonly use readonly for lists or other collections that i don't need to assign in the inspector but don't want new instances created for, pretty handy for things like buffers used for non allocating physics queries

swift crag
#

I use it because the linter tells me to

rich adder
#

usually VS tells me , only usually happens on newer .NET apps I work on , never gotten it in unity UnityChanThink

swift crag
#

It is somewhat nice to know that a variable will never be reassigned

timber tide
#

until you do and then it yells at you to remove it

Can I put multiple layers on one object? I want something to have a layer that marks at as an obstacle that blocks raycasts, but also something that gets picked up by a sphere overlap, but I’ve only been able to put one layer on an object

languid spire
timber tide
#

that's not a bad idea otherwise make an interface of tags

hidden sleet
#

K, so would you just put empty game objects on the child of some mesh and put layers on those?

languid spire
#

yes, exactly

hidden sleet
#

Alrighty, sounds like that would do the trick

#

Although why can’t you put multiple layers on when tags work just fine?

languid spire
#

Ask Unity

timber tide
#

Unity tags stink

hidden sleet
#

I’ve not used them in a while

timber tide
#

even if you search by tag you still need to do a component search to grab the exact object (also you can only have 1 tag??)

rich adder
hidden sleet
#

In what way

languid spire
#

If Unity used a LayerMask at GameObject level instead of Layer then multiple layers could be a thing and it would make RayCasting a lot simpler

hidden sleet
#

Cause this is just to physically block a raycast but also allow another raycast through

rich adder
#

I usually combine Layers and then specific objects further, through components

languid spire
#

tbh as Layer is just an int there is nothing to stop you making it a LayerMask and using it as such

hidden sleet
#

I’ll try out the child objects idea and see what happens

How to I make the arrow faces toward the target ?
Do I take the Vector3 of the target and minus it to the object that's shooting ?

Like Vector3(target.x,target.x,target.x) - Vector3(shooter.x,shooter.x,shooter.x) ?

There's like a handful of ways to move in unity

Did you turn on interpolation for the bees Rigidbody? @gray crest

gray crest
wintry quarry
#

Well then that's your issue

#

You're seeing non interpolated physics motion

#

Which is at 50hz by default, not matching your framerate

gray crest
wintry quarry
#

You changed it to what?

#

And wdym "weird thing where they slow down"?

gray crest
wintry quarry
#

I presume that's a result of your code

gray crest
#

as you can see they are still blurry, also in the future i plan to speed them up to make the game harder so they will be even harder to se

wintry quarry
#

I think your Smoothdamp call is a little sus

#

For the moment I would simplify the movement code to a constant velocity to sort these issues out

#

Then start introducing the weird smoothdamp and sin wave stuff

gray crest
#

okay let me try

gray crest
# wintry quarry I think your Smoothdamp call is a little sus

so ive done this, ```using System.Collections;

private float amplitude;
private float frequency;

void Start()
{
    rb = GetComponent<Rigidbody>();
    frequency = Random.Range(1f, 12f);
    amplitude = Random.Range(1f, 2f);
}

void FixedUpdate()
{
float x = amplitude * Mathf.Sin(frequency * Time.time);
float y = amplitude * Mathf.Cos(frequency * Time.time);
Vector2 waveMotion = new Vector2(x, y);

// Calculate the target velocity
Vector3 targetVelocity = new Vector3(-enemySpeed, 0, 0);

// Assign the target velocity directly to the rigidbody
rb.velocity = targetVelocity;

OK how to fix this then? my character falls very slowly if I move left or right while in air, I want it to fall normal.

^ this, ur setting velocity to Vector2.right * speed;

queen adder
# 
public void kretnja()
{
    if (Input.GetKey(KeyCode.RightArrow) == true)
    {
        igrac.velocity = Vector2.right * speed;
    }

    
    


    if (Input.GetKey(KeyCode.LeftArrow) == true)
    {
        igrac.velocity = Vector2.left * speed;

    }
    


    if (Input.GetKeyDown(KeyCode.UpArrow) == true && Grounded)
    {
        igrac.velocity = Vector2.up * JumpStrength;
rocky canyon
#

that means ur setting ur Y velocity to 0 each frame.. stopping it from falling

queen adder
rocky canyon
#

in ur vector use the rigidbody's y velocity as the Y value

polar acorn
rocky canyon
#

igrac.velocity = new Vector2(speed, igrac.velocity.y);

#

-speed for left

queen adder
#

new vector2 is my custom vector2 right?

rocky canyon
#

yes

#

one that u can construct urself.

queen adder
#

yes yes I get it

guys i have 2 objects one has a player layer and another one that has the projectile layer as as you can here i disabled their collision with each other but they can still collide with each other

#

thanks, it works like I want now. can you explain what (speed, igrac.velocity.y) means is igrac.velocity.y the direction of moving, and speed the multiplier, it kinda doesnt make sense, I think it should be (speed * igrac.velocity.y) can you elaborate @rocky canyon @polar acorn

polar acorn

X and Y

#

speed is X

#

igrac.velocity.y is Y

wanton crater

how do i specifically set the x value of a transform function

polar acorn
autumn tusk
#

sorry wrong wording

#

but yeah how do i only change the x value of a transform

polar acorn
#

Transform doesn't have an X value either

queen adder
#

so speed(x) is telling y how much to move in y direction?

hi i have an animation for my 2d object that is supposed to only be played when i tell it too, instead it plays as soon as the game starts and i dont know how to make it not

Hey I am trying to make a simple 2D game but I have never developed a 2d game only 3d also it has been a while since I have used Unity anyway what would be the best way to have a sprite move up and down with gravity ex press button sprite goes up release it goes down

polar acorn
queen adder
#

yeah it goes from entry to the animation, i understand that would start on start but idk how to make it so it only starts when i want it to

#

do i have to make a seperate animation that does nothing

swift crag
#

Correct. The entry state is entered the moment the animator starts working.

#

It's the default state.

The same way you would with 3D, use forces on a rigidbody. Nothing changes in that regard.

polar acorn

What do you mean "interfere with other rays"?

vale geode
polar acorn
vale geode
#

the camera goes to the other object

swift crag
#

This does not make any sense.

#

What is a "ray" here?

#

It does not sound like a "ray" I'm familiar with.

rich adder
vale geode
#

red is from the player raycast and withe is from the object ray cast, the player camera gets stuck to the new ray location

1question.JPG 2question.JPG
polar acorn
rich adder
polar acorn
#

The rays don't do anything, they just check if they hit something

#

If this white ray is moving the camera, it's because your code that casts the white ray tells the camera to move

vale geode
swift crag
#

this especially doesn't do anything

polar acorn
# vale geode

Okay, so this ray seems to just draw a debug line. It doesn't actually do anything ever

rich adder
#

player.transform.position = transform.psotiion ?

polar acorn
#

Ah, actually

#

Why are you teleporting the player to this spot

rich adder
#

they probably put = instead of -

swift crag
#

ah, that'll do it

polar acorn
#

this has nothing to do with the ray, you're just setting three things equal to each other

Hi. Are there any good articles for when to use scripts? From an engineering standpoint

polar acorn
#

You use scripts when you need to script something

swift crag
#

that's pretty vague, yes

young fossil
swift crag
#

the platonic ideal of a component is to do a specific job very well

polar acorn
young fossil
swift crag
#

you often create components that form an inheritance tree

#

and then combine them via composition

#

that's how my game works

#

every "thing" in my game that can meaningful act is an Entity. Entities have Modules, which provide specific features:

  • being visible
  • offering interactions to other entities
  • being able to hear things
young fossil
#

It may be better to discuss examples.

Like Enemy and Player scripts. They are both "characters". But inheritance doesn't seem to be the obvious route there in most Unity projects

swift crag
#

you can still have classes that inherit from others

#

so you could have an abstract class that is subclassed by Player and Enemy, if there is common behavior between them

swift crag
#

This was a rewrite from my original design, where I had some ... very large classes for "Player" and "Enemy"

swift crag
#

I previously had really janky code in the Player class so that it could be an AI or a human-controlled thing

frail star
#

Anyone know of any how-to's on letting players upload an image to set as a background , or even take images to set as backgrounds?

swift crag
#

you would need a library that can read image files and give you pixel data, which you'd then store into a Texture2D

#

or even take images to set as backgrounds?

This would be possible through a camera on the player's device

#

ah!

#

It can undersatnd JPEG and PNG data.

#

You'd just read the file as a byte array, then use ImageConversion.LoadImage

hey, i made (followed a youtube tutorial) a car controller script thing. it works until i try making the wheels visuals work.
the part of the script used is

void FixedUpdate{
// the rest of the script that makes stuff work
 UpdateWheel(frontLeft, frontLeftTrans);
        UpdateWheel(frontRight, frontRightTrans);
       UpdateWheel(backLeft, backLeftTrans);
        UpdateWheel(backRight, backRightTrans);

    }

void UpdateWheel(WheelCollider col, Transform trans) {
        Vector3 pos;
        Quaternion rot;
        col.GetWorldPose(out pos, out rot);
        trans.position = pos;
        trans.rotation = rot;
    }

the car flips horribly when the wheel turning part is added. does anyone know why it does this?

thanks!

How do you set the color of a line renderer via script ?

shell sorrel
#

has startColor and endColor properties

stable moth
shell sorrel
#

can set them when ever you want to change the color via code

carmine sierra
#

searched but couldn't find one

#

also I placed my UI's into an empty gameobject and now they are not appearing

rich adder
stable moth
# 
line.SetstartColor(PhotonVRManager.Colour);
line.SetendColor(PhotonVRManager.Colour);```
This is the portion of code
rich adder
carmine sierra
shell sorrel
carmine sierra
#

was wondering what that was

shell sorrel
#

its just properties line.startColor = wantedColor

gloomy bison
carmine sierra
#

how does it spread the sprite across the material

#

the material across the image i mean

stable moth
shell sorrel
#

line.startColor = PhotonVRManager.Colour;

#

and do the same for endColor

rich adder
#

Line renderer itself has different modes of rendering

#

make sure it set to Tile or the other ones, not stretch though

stable moth
shell sorrel
stable moth
#

I say there was PhotonVRManager.SetColour in an another script

stable moth
shell sorrel
#

that means you need a object of PhotonVRManager not just its class

#

how do i know an object

i hate the fact ```csharp

i'm working on my first game, it's a 3d world but there's an arcade machine i want the user to be able to play a little 2d mini-game on.
I've basically got it all setup but I don't know if I'm taking the correct approach to it.
In the picture I will provide, the scene to the right there's a cinemachine virtual camera that will be close up to the arcade machine screen.

in the right scene i have another camera that renders a 2dGames layer and the arcade machine has a render texture for the monitor.
this works just fine if i'm just taking in keyboard input to move the spaceship around. but i want aiming to be done with the mouse and i'm struggling to find out how to correctly translate screen points of the mouse position so that the 2d spaceship will rotate and aim at the mouse position.
what should I try to get this to work? is there a way to just get where the mouse position is at on the screen like viewport and just use that as where the mouse would be located for the render camera?

#

also i'm not sure if it matters but the arcade machine is away far away from the 2d render camera and they are oriented differently. for example, the arcade machine is facing east lets say and the render camera is pointing north

# tame mist

Idk if you know but you can add a scene inside of another scene. Called additive scenes I think. Look that up on google or YouTube

summer stump
minor patio
#

so I've got this null reference that I just don't know what to do about: I have a game object that has a 'Representative' class attached (a player character), and I have a 'Specialisation' class (a class that describes a skill) that I have a method in that requires a 'rep' object to calculate the skill's score. Problem is the rep object is null and all the 'getComponent' tricks I know are insufficient to fetch the required data. I'm beginning to think that this is one knot I just can't undo...

#

idk if i can really help you without understanding this properly though...

wicked cairn
# tame mist additive scenes sounds like a really cool feature but i'm not sure how that's go...

Additive scenes means whatever is in the other scene gets added to your current scene, but under the parent hierarchy of that scene. When a player reaches the arcade machine it could prompt if they want to enter, if yes, it could add the new scene then disable the current camera, or of course not and just use one camera from the main scene, again the additive scene is just adding more objects to your scene

#

hmm for the mouse position im not sure. possibly youtube making something follow the cursor, and keep the object(fake mouse) that follows the cursor in bounds of the machine screen

#

could stack ur rendertexture camera and (everything it see's on top of ur main camera) and just cull out the machine and everything you're looking at.. taht way ur mouse positions would be the same for both camera's

Lovely people on the Unity Discord code-beginner chat. I need help.

As you can see in the video, an enemy throws a bomb towards the player and the bomb explodes after a few seconds. I'm trying to instantiate an object at the location of the bomb explosion when it explodes, but I can't figure out how to do it. What I'm struggling to figure out, is how to get the position of the explosion. If anyone has any ideas, I'd really apprecaite it

gaunt ice
#

transform.position?

slender nymph
#

yeah the position of the explosion would be the position of that thrown object at the time the explosion happens. i'm honestly confused as to how that isn't obvious

west sonnet
#

The thrown object is a particle

#

So If I do the transform.position of the particle system, it uses the position of the particle system, not the particle itself

#

My bad, forgot to mention it's particles

timber tide

looks like it's working in the video no?

                }          
            }            
        }

```\
gaunt ice
#

do you notice that once you fly up again the previous particle disappear

timber tide
#

dont pause them

#

actually I see the problem. I don't use the shuriken system much, but you probably want to stop emitting, but not pausing the system

#

otherwise pool independent systems

silent vault
#

Does the number of components affects performance? For example, I have 2 methods I want execute in Update but since they deal different matters, I prefer to have 2 different components. Will it run slower than having 1 component Update doing both methods in the same loop? Obviously for a difference of 1, it won't matter but if we stretch that to having 10 small components instead of 1 big component and then having 10 of this gameobject in the scene?

wintry quarry
timber tide
#

eh, worrying about micro optimizations, but ideally you want to keep your game objects less populated with components (specifically the ones with colliders) so GetComponent can grab what it's looking for quicker.

#

More of an issue when these checks are happening per update.

silent vault
#

Ok Thanks

wintry quarry
#

When I say "affects performance" that doesn't mean "significantly"

#

In the same way dropping a bucket of water in the ocean "affects" the sea level.

silent vault
#

Ahah, got it. Thanks 🙂

charred spoke
#

Technically at the scale of lets say 10,000 it is better to do 10,000 methods cals inside a single Update, than having 10,000 individual updates.

Hi, how can I put this event in the second code?

#

Second code:

timber tide
#

Few ways, one is being give every Health class a reference to your MainGame object which you probably have one of

#

The more typical ways people use these game manager objects is by making them into singletons which means that they become the only instance of that object type

#

This way you can just reference the class type (with an extra dot operation) without worrying about passing that reference into all of your objects

young warren
#

is there a reason you can't create a MainGame type variable in Health.cs and assign it like you did for mainOver in MainGame?

#

I recommend going through this guide and see which one works for you

#

I suspect Dependency Injection would be suitable for your case

verbal meteor
timber tide
#

Ah, so you do pass the reference in, but as a gameobject.

#

Either be more specific on the type (make it a type of MainMenu and add it on the inspector) or do a GetComponent call assuming you know the GameObject has a MainMenu component

verbal meteor
timber tide
#

Consider doing it all on the inspector though

#

You may be assigning the wrong object then ^

verbal meteor
timber tide
#

Stick to calling the GameOver method since it's more relevant to the GameManager than the player

Sorry, I'm a beginner i don't know exactly what you mean.

MainMenu is a component of GameObject, but if you assign it as GameObject you need to use GetComponent to grab it from it. Otherwise, change the type to MainMenu specifically and assign it as is in the inspector

you could also use an anonymous type, if you really want names
Action<(int myNamedVariabel, int someOthername)> callback;
but imo, it makes both the invocation, and the subscriber signature a little messy. but up to you

why is it causing a clicking noise?

its like a really quiet click noise

u probably wont be able to hear it on video

well you're playing a sound, no?

yes but im destroying the sound after its finished playing
Destroy(newObject, clip.length + 0.25f);

i even added 0.25f just to be safe

and setting the volume to 0 just before i destroy it

also didnt work

# tender stag why is it causing a clicking noise?

Well, i created a whole audio system for the "clicking noise" before. If you don't wan't that behaviour, use a third party audio system because you will encounter later on even you fix that one. FMOD Suggested.

tender stag
tender stag
wintry quarry
#

the gunshot?

tender stag
#

yeah

queen adder
#

Basically, the clicking noise happens when the music stops, a small gap happens between frequencies if the frequency is high enough. This gap causes a "clicking noise". How to fix it? Only way is to delete that high frequency when you stop the audio. In other words, mute or fade out. But yeah FMOD is all good they thought about everything.

wintry quarry
#

maybe just shoot once so it's not masked haha

tender stag
#

wait it doesnt happen for the ak

#

maybe its cause the sound doesnt fade out properly?

guys i have a bit of a unique problem that idk if it has a fix or not
so basically i have this lighting attack that bounces from enemy to enemy using the script below (on top there is "OnCollissionEnter2D")
the thing is since this is "OnCollissionEnter2D" and not "OnCollissionStay2D" if 2 enemies and really close to each other to the point the collision box of the lighting projectile that this script is attached to dosent leave the collider of the the first enemy hit when it hits the second enemy it targets back to the first enemy since its the closet enemy but since the colliders are still touching from the first time he got hit it dosent register it as a collision enter
a logical fix would be to change OnCollissionEnter2D to OnCollissionStay2D but that would make the first enemy get hit 3 times instead of the projectile bouncing 3 times
is there a way to fix this?

hello, so i'm trynna fix my character's diagonal movement and apprently only one condition can be true and so the player can't walk diagonally. if i press the right arrow key, then the up arrow, the right movement is cancelled and the player goes up

wintry quarry
ornate lynx
#

that makes sense

wanton crater
ornate lynx
#

shall i make another condition where left or right and up or down are pressed?

wintry quarry
#

Try something like this @ornate lynx

Vector2 move = Vector2.zero;

if (horizontalStuff) {
  move += new Vector2(...);
}
if (verticalStuff) {
  move += new Vector2(...);
}
transform.Translate(move...);
#

see how I'm using +=?

#

So they can both affect it

ornate lynx
#

yeah yeah

wintry quarry
ornate lynx
#

so it's like i'm summing the old vector wh=ith the new one is that right?

wintry quarry
#

you should just do this:

Vector2 move = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
transform.Translate(...);```
#

much simpler

ornate lynx
wintry quarry
#

no need for if statements, checking individual keys, etc..

ornate lynx
#

oh

#

well, you know, i'm beginner, trynna make code i can understand for now

wintry quarry
ornate lynx
#

will make it more compact at a later point

wintry quarry
#

What part is confusing?

ornate lynx
#

no, well, idk, seems easier for me in if statement

wintry quarry
#

what does the if statement add here? Input.GetAxis already tells us the value of the axis (aka the keys being pressed)

#

if they're not being pressed, it will be 0

#

which is as expected

ornate lynx
#

i wrote that line at first, and forgot to transform.translate and i thought using that line was wrong 💀

Hi! Can someone help with questions concering data persistence and input fields? It's something I've found a ton about online, but I'm failing to understand how to apply what I'm reading. What I want to achieve is:

  • Type the player name in an Input Field on Scene 0
  • Load Scene 1
  • Display the text from the Input Field in a TextMeshPro in Scene 1, as part of the scoring text (which alreadys works). It would be: "<player name>'s score: xx"

How would I do this? I'm struggling with:

  • Writing code that takes the player input
  • Storing/saving that player input somewhere
  • Sending that input as text to display to my other scene

Here's 2 screenshots of my current game.

swift crag
#

For data that there can be only one copy of, a static field is a reasonable choice.

#

a static field is part of its class, rather than being part of instances of that class

#

so, you can access it from anywhere

dusk musk
swift crag
#

figure out how to log the contents of your input box when you click a button

#

then you just need to store the text into a field instead of logging it

dusk musk
swift crag
#

okay, so instead of printing it, you need to store it in a static field

#

creating a static field is easy: just add the static modifier to a field defintion

# 
public static string playerName;
#

for example

dusk musk
# 
    public static string playerNameInput;

    public void ReadStringInput(string playerNameString)
    {
        playerNameInput = playerNameString;
        Debug.Log("Player name: " + playerNameString);
    }
dusk musk
buoyant knot
#

i’ll always take a singleton over a static field, even tho a singleton uses a static field to function

buoyant knot
# dusk musk Like this? 🙂

that would work, but because it is static, it is 1) harder to debug, 2) persists, 3) hard to track down changes

swift crag
#

You write to it on the menu scene and then read from it elsewhere

#

You don’t need to create an elaborate contraption to hold the string

buoyant knot
#

i wouldn’t call a singleton an elaborate contraption, if you just inherit from a class someone else wrote

dusk musk
#

Thanks for your help both. I'm now going to do some experimenting with showing the input field in another TMP on the Menu scene. if that works, I'll try to get it to show on the next Scene.

swift crag
#

It’s trivial to find who changes the field.

buoyant knot
#

for that I use a singleton that is DoNotDestroyOnLoad

#

this should work tho

swift crag
#

Static fields live for the entire duration of the game

buoyant knot
#

which is why I have a kneejerk reaction to defining static fields

dusk musk
swift crag
#

Static fields have nothing to do with Unity at all.

buoyant knot
#

of the whole program

swift crag
buoyant knot
#

i’ve been screwed over by static fields a lot, so it is hard to unlearn

swift crag
#

creating a static field to store a reference to a class that holds a single field is functionally equivalent to creating a static field in this situation. there are certainly scenarios where they aren't equivalent, but this isn't one of them

buoyant knot
#

my concern is abuse/overuse associated with starting to use them, and never learning the downsides

Hello, guys! I want to implement a Game Mechanic for my game. So, I am making a flappy bird game and I want to increase speed of my tree logs everytime I am making +10 score. Here is how it looks like right now because I am currently increasing the speed gradually. Can someone help me with that please I stuck on that and don't know how to make it?

buoyant knot
#

just follow the tutorial from game maker’s toolkit

sage mirage
buoyant knot
#

he literally makes flappy bird from start to finish

sage mirage
#

The problem is that I am already at the end of the process

#

I have only one game mechanic to make and I am fine

dusk musk
swift crag
#

you'll need a reference to the component

#

TMP_Text is the type you want.

ivory bobcat
swift crag
#

It works for both UI and non-UI text.

#

You will need to add using TMPro; up top, since that's the namespace this class comes form.

#

TMP_Text.text lets you set the text it displays.

sage mirage
# ivory bobcat Maybe consider showing your implementation 


public class MovingUpDownLogs : MonoBehaviour
{
    [SerializeField] private float currentSpeed;
    [SerializeField] private float minY;
    [SerializeField] private float maxY;
    [SerializeField] private float speedIncreaseFactor;
    [SerializeField] private float maxSpeed;

    private bool movingUp = true;


    private void Update()
    {
        if (movingUp)
        {
            transform.Translate(Vector3.up * currentSpeed * Time.deltaTime);
            if (transform.position.y >= maxY)
            {
                movingUp = false;
            }
        }
        else
        {
            transform.Translate(Vector3.down * currentSpeed * Time.deltaTime);
            if (transform.position.y <= minY)
            {
                movingUp = true;
            }
        }
        IncreasingSpeedOfTreeLogs();
    }

    public void IncreasingSpeedOfTreeLogs()
    {
        if (currentSpeed < maxSpeed)
        {
            currentSpeed += speedIncreaseFactor * Time.deltaTime;
            currentSpeed = Mathf.Min(currentSpeed, maxSpeed); // Ensure speed doesn't exceed maxSpeed
        }
    }
}

Here is my class that moves the tree logs!

dusk musk
sage mirage
#

So, I am thinking to use my IncreaseSpeedOfTreeLogs() inside my UpdateScore() method

ivory bobcat

Yeah maybe let me try give me a minute

hi, how can i add a one time force to a rigidbody?

buoyant knot
#

AddForce using ForceMode.Impulse

dusk musk
# swift crag `TMP_Text.text` lets you set the text it displays.

Wow I think I figured it out!

    public static string playerNameInput;

    public TextMeshProUGUI playerName;

    public void ReadStringInput(string playerNameString)
    {
        playerNameInput = playerNameString;
        Debug.Log("Player name: " + playerNameString);
    }

    public void Update()
    {
        playerName.text = playerNameInput;
    }
image.png
ornate lynx
#

it's gonna happen only once?

ivory bobcat
#

Also, you probably don't need to be multiplying current speed by delta time in the accumulation of speed - Update would be relative to this frame thus why it's necessary in Update.

swift crag
#

that's the general idea for a lot of tasks

#

get a reference to the thing you need (usually by dragging it into the inspector) and then do stuff to it

ornate lynx
dusk musk
buoyant knot
swift crag
#

Non-static members (fields, methods, etc.) are part of a specific object, like public TextMeshProUGUI playerName

#

You can assign them in the inspector for each instance of the component

#

Static members are part of the class, like public static string playerNameInput

ornate lynx
#

is there a way to call it once in update method?

swift crag
#

sure, slap a bool field in that you set to true after the first time you run the method

wanton crater
#

should i make all my player stats as in attakc damage / health / range.... as public static?

swift crag
wanton crater
#

so any script that wants to change them can instantly do

swift crag
ornate lynx
#

my player is sliding so i'm adding a brief force as counter movement to stop it

wanton crater
swift crag
#

It would make a lot more sense to just pass the player themselves to the components that need to modify the player

#

You could make the player a singleton, I suppose.

wanton crater
#

im still new i don't know what a singeton is

swift crag
ornate lynx
swift crag
# wanton crater what

stats are a property of the player in the scene (a Player component on a game object), not just the abstract concept of a player (the Player class)

swift crag
ornate lynx
#

alr alr

swift crag
#

Set it to true when you apply the force and set it to false when you move again

ornate lynx
#

got it

buoyant knot
#

i try to avoid doing things in Update unless I kind of need to

ornate lynx
#

i'm programming the player's movement sooo

wanton crater
dusk musk
# swift crag Right.

To be honest, I'm lost again. 😅 It's mainly a thing of not understand how to describe what I'm trying to do. I'm still missing some of the vocabulary, is what I'm feeling... Anyway. In my other scene, where I want the player name to show up: how do bring over the static string? I know how to get text to display in my scene. But how do I get the string from Scene 0, to Scene 1?

buoyant knot
#

then the force should be added in response to an invocation of player jump or something

sage mirage
buoyant knot
#

update should generally be used to capture input tho

ornate lynx
#

yes?

buoyant knot
#

but actually applying force would be done once per fixed update

ornate lynx
#

when is fixedUpdate called?

ivory bobcat
wanton crater
buoyant knot
#

by default, 50/s

swift crag
ornate lynx
#

soo fixedUpdate is not a solution is it?

buoyant knot
#

regular update could be called 50 to 600 times in a second

swift crag
#

The player's component is probably not attached to the enemy

ivory bobcat
buoyant knot
#

partially

swift crag
# 
rb.AddForce(whatever, ForceMode.Impulse);
buoyant knot
#

so Input.GetKeyDown is true for exactly one frame, which may or may not be a fixed frame

ornate lynx
#

yes i have this exact line in update

sage mirage
ivory bobcat
#

Where you'd cache the instantiated tree and modify its speed value based on your stored score.

wanton crater
#

@swift crag look
i have a script and i wnat to it change a value in another script
should do that private variable and get that componenet and change it or make the variable i wnat to change a static or what

buoyant knot
#

but you should not do physics things in regular update, since the timing can get wacky, since physics sim isn’t even done that frame!

ornate lynx
swift crag
buoyant knot
#

so in general, with the default Input system, you want to query player input and store variables in Update. Then actually action on them in FixedUpdate

swift crag
#

Alternatively, if you didn't use a singleton, you'd need to provide a reference to whoever needs to modify the player

# 
public void GivePowerup(Player player) {
  player.attackDamage += 100;
}
ivory bobcat
swift crag
#

This could be called when the player collides with the powerup

#

In that situation, you would use GetComponent to get the Player component after colliding with the player

ornate lynx
buoyant knot
swift crag
# 
void OnTriggerEnter2D(Collider other) {
  if (other.TryGetComponent(out Player player) {
    player.attackDamage + 100;
  }
}

That would be reasonable.

#

TryGetComponent returns true if it manages to find the component you asked for

ornate lynx
swift crag
ornate lynx
#

except the last sentence

buoyant knot
wanton crater
#

thanks @swift crag

buoyant knot
#

you might have 20 frames between fixed frames

#

you might have 1

#

or zero

#

you don’t know

ornate lynx
#

i'm sorry mb but i still don't get it

buoyant knot
#

so the code needs to handle the distinction

swift crag
buoyant knot
#

unity has frames and fixed frames

ornate lynx
#

why i should use fixed update

ornate lynx
buoyant knot
#

physics simulation only happens on fixed update

ornate lynx
#

physics like adding force?

swift crag
#

AddForce just adds your force to a running total.

buoyant knot
#

the whole putting of bodies in motion, changing velocities, collision callbacks, contacts… NONE of this shit happens on non-fixed frames

swift crag
#

The force is acted upon in the next physics update.

#

I wouldn't call them "fixed frames", since they're not frames at all

#

it's just an update loop that runs at a fixed cadence -- 50 times per second

ornate lynx
#

so u suggest that i detect the input in Update and actually do that physics stuff in fixedUpdate

swift crag
#

that means you get 0, 1, or many fixed updates per rendered frame

swift crag
#

Reading input in Update is important because things like Input.GetKeyDown care about exact frames

#

GetKeyDown is true for one frame

hollow dawn
#

im a beginner at coding c# i know how to use unitiy/know the basics. whats the fastest/best way to learn c#

swift crag
#

If you check for input in FixedUpdate, you might miss that frame entirely

hollow dawn
#

c#?

buoyant knot
#

if you give a grounded player +5 Y velocity in update, then next update check that he is on ground to try a jump, the player will still be on the ground if a physics update/fixed update hasn’t happened yet!

swift crag
#

vitally:

image.png
buoyant knot
#

you gave the player velocity, but physics system doesn’t DO anything with it until it is time for physics sim.
which happens on fixed frames, and not on non-fixed frames

#

do you understand?

Hello, I have a problem that I can't find the answer for online, so I was hoping someone could help here is what im trying to do: I want to make a "Bullet" hit a "Enemy" by using tags but when I shoot the "Enemy" nothing happens not even my Debug output, Here is my line of code, if you need more I could screen shot my whole thing: void OnCollisionEnter()
{
if (GameObject.FindWithTag("Test"))
{
TakeDamage(20);
Debug.Log("HIT");
}

}
swift crag
#

your method's parameters are wrong.

buoyant knot
#

this is why you don’t want to do anything physics related in Update. Because that is not the frequency with which physics updates happen

swift crag
#

Go through these pages.

ornate lynx
dusk musk
swift crag
#

a NRE means you have a null variable you're trying to do something with

#

therefore, something on line 23 is null

buoyant knot
#

anyway, i hope that clears things up

ornate lynx
#

i'm reading over and over to better understand it

ornate lynx
#

i kinda get it now

#

so when i press the spacebar, the player doesn't jump at the exact moment i pressed, he actually jumps when a fixed frame happens while i'm pressing the spacebar

buoyant knot
#

Input goes off EVERY frame, fixed or not. So if you ask Input if this is the frame where spacebar was pressed down, it may or may not be on a fixed frame

buoyant knot
#

So you need to capture wtf Input is doing in Update, then actually do physics in FixedUpdate

ornate lynx
#

ok so i need to detect the input from Update(), make some variables to work with to add the force in FixedUpdate()
