im doing a course on Udemy and there is something that don't make sense to me.
we created a weapon script https://gdl.space/azovihujol.cpp
and added dropped weapons from dead enemies (cool) but they are also moving and shooting even before I picked them up (it make sense since we didn't check anywhere in the code if the are equipped)
am I missing something?

Sorry, I read again, yes I think it's a typo in the method code

this stuff is so frustrating, I have no experience with this, there's no explanation, just a random code snippet that doesn't work, dunno where to put it, what to do with it, why it doesn't work, what it's purpose is ...

Yo guys,im. Creating a card game and im using horizontal layout group,how can i make the cards in hand to have that curvy while still using hlg

frosty hound
#

You're going to be fighting against the layout group if you want to keep it only for the horizontal position.

But anyway, if you do, then you need to move the card as a child object of the parent that is controlled by the layout group.

You would offset the child position (vertically) and rotate it. The amount you would, would be a lerp between default position (no movement) to max movement based on how far from the center of the layout group the card is.

Will i win the fight?

Is it good practice to split FSM for character controller state and animation?

timber tide
#

Usually all that logic runs in parallel

#

the blend tree is basically a FSM machine anyway, but it's still useful for when you need to blend stuff together

Hi... A question for all those Math lovers.. I have a sphere droid with different cannons around it (a cannon is a a child transform that looks outwards). What is the right formula to rotate it so a random cannon will face front?

 private IEnumerator BounceTowardPlayer()
 {
     while (true)
     {
         // Wait for a random duration before jumping again
         yield return new WaitForSeconds(Random.Range(0.1f, 0.5f));

         // Jump if the enemy is grounded
         if (isGrounded)
         {
             Jump();
         }
     }
 }
#

my enemy is a slime thing so i have it look like its bouncing

rich adder
willow scroll
#

then just rotate using a coroutine with lerp

verbal dome
#

Quaternion.FromToRotation can be useful here

willow scroll
#

each cannon will have their own target rotation

#

like (0, 0, 0), (90, 0, 0), (180, 0, 0) and (270, 0, 0)

verbal dome
#

Something like this could workcs List<Vector3> directions = /* list of directions corresponding to the cannons, in local space */ int index = Random.Range(0, directions.Count); // Random direction idex Vector3 dir = directions[index]; Quaternion lookRotation = Quaternion.LookRotation(enemyPosition - myPosition); lookRotation = Quaternion.FromToRotation(Vector3.forward, dir) * lookRotation;

#

Untested, might need to flip the last line

#

And yeah, using rotations instead of directions is an alternative like password123 said

willow scroll
#

I wonder if they want to find the nearest cannon to the enemy

#

this way the target rotation should be lookRotation - nearestCannonRotation

#

I suppose

soft flume
#

Thanks. I don't mind it not being the nearest cannon. I just tried so many calculations and it doesn't work right

#

I will try to play with the @verbal dome code and see. Thank you!

verbal dome
#

And the left & right side of the last line might have to be flipped, I forget how Quaternion multiplication order goes

I'm trying to Instantiate a prefab of enemies but all enemies share a healthpool and i cant interact through C# with any particular instance, just the prefab itself.

timber tide
#

don't interact with the prefab itself

simple forge
#

well yes, but how would i do that ?

timber tide
#

You actually get the reference to the object when you instantiate it

#

store it somewhere safe

simple forge
#

im REALLY a beginner, no clue how to do that either

timber tide
#

You've written anything, specifically for instantiating those prefabs?

simple forge
#

yes

timber tide
#

post it

            GameObject enemyClone = Instantiate(enemy, new Vector3(i, enemy.transform.position.y, i), enemy.transform.rotation);
            enemyClone.transform.parent = enemyContainer.transform;
            enemyClone.name = "Enemy" + (i+1);
        }
    }
}
timber tide
# 
GameObject enemyClone = Instantiate(enemy, new Vector3(i, enemy.transform.position.y, i), enemy.transform.rotation);

Alright, so you do get the reference to the gameobject here

simple forge
#

so i just replace everything with that ?

#

well, what is referencing the enemy

timber tide
#

You don't actually store the reference is the problem, unless you're accessing it from elsewhere

#

How are you doing damage to the enemy. Can you post that?

simple forge
# 
using System.Collections;

public class EnemyHealthTracking : MonoBehaviour
{
    public int health = 100;
    public void TakeDamage(int damage_ammount)
    {
        health = health - damage_ammount;
        Debug.Log(health);
        if (health <= 0)
        {
            this.gameObject.SetActive(false);
        }
    }
    
}
#

it wouldnt let me delete it since i was trying to delete the prefab thats why its disabling it instead

timber tide
#

So, your prefab has this component on it, yeah?

simple forge
#

yes

timber tide
#

Now, what method are you using to grab that specific gameobject instance that's now on the scene.

#

collider detection, casting, ect

raycasting yes

Heey, does anyone knows how can i export terrain textures on a jpg to apply them to a plane? 🧐

timber tide
simple forge
#

what should i implement instead ?

timber tide
# 
if (Physics.Raycast(ray, out RaycastHit hit, Mathf.Infinity))
{
    if (hit.collider.CompareTag("Enemy"))
    {
        EnemyHealthTracking enemy = hit.collider.gameObject.GetComponent<EnemyHealthTracking>();

        Debug.Log("Enemy hit is: " + enemy.name);
    }
}```
#

something like that

#

I suggest layers instead of tags though

#

which you should watch tutorials of

#

But to clarify what I'm doing here is I grab info from the hit and check if these gameobjects of these colliders have this class type instance (their hp class)

simple forge
#

thank you for the help, while you were typing that up i found a solution on the forum since i knew what to look for

#

i found this on a forum

timber tide
#

yeah, there's a lot of info out there for this stuff

simple forge
#

yeah, ive been looking for a while but didnt know what to look for exactly

#

Thanks

timber tide
#

should remove this too:

public EnemyHealthTracking enemyHealthTracking;```
as you shouldnt need to store a 'single' instance of your enemy here
#

you'll get their instances/references on demand from the cast

#

Is it possible to have a script run on a de-activated game object at all? As strange as that sounds.

timber tide
#

de-activated should just stop update and other unity methods

simple forge
lone sable
#

Yeah thats the problem I suppose.

#

Was hoping there was like a [AlwaysExecute] type thing.

#

Specifically, the problem I'm trying to solve is that, sometimes, when modifying the UI, I'll disable objects that need to be re-enabled.

#

And I'll forget lol. So, was hoping to just toss a script on them.

timber tide
#

if you need like coroutines to run, you can make like a singleton manager that re-enables the UI objects

#

I do something similar

willow scroll
timber tide
#

Oh, do coroutines still run? I thought they didn't.

willow scroll
timber tide
#

my coroutine manager too sweet to remove though ;)

steel pier
#

I have a script where when i left click a gameobjects follows my mous movement. but wenn the size is negativ you cant see the gameobject

timber tide
#

because you're flipping it

#

and it's backface culling the quad

steel pier
#

How could i fix it ?

willow scroll
#

so you don't have to remove your sweet coroutine manager

timber tide
willow scroll
#

could you, please, show your code?

#

basically you have to abs your GameObject's size

# 
        Vector2 size = mousePos - initialMousePosition;
        selectionBorder.GetComponent<RectTransform>().sizeDelta = new Vector2(size.x, size.y);
        Vector2 checkScale = new Vector2(size.x, size.y);
        selectionBorder.GetComponent<RectTransform>().anchoredPosition = (mousePos + initialMousePosition) / 2f;

"You can’t have a rectangle with negative dimensions.
What you need to do is create a rectangle that has positive dimensions starting from the point where your mouse is to the point where the drag operation started.
Basically, when your mouse X and / or Y are negative you will be redrawing the rectangle FROM CURRENT location of your mouse pointer to the START OF DRAG location.
In cases when they are positive then the logic stays as you have it since your are drawing the rectangle FROM START OF DRAG location TO CURRENT mouse position."

Now that I understand the question, here’s your answer: http://docs.oracle.com/javase/6/docs/api/java/awt/Rectangle.html A Rectangle whose width or height is negative has neither location nor dimension along those axes with negative dimensions. Such a Rectangle is treated as non-existant along those axes. Such a Rectangle is also empty with re...

#

If I were to do it I'd just draw my own quad honestly

willow scroll
#

please, note that it'll work just if both of your pivot is exactly (.5, .5)

#

if you need to change your pivots for some reason, you'll have to implement additional logic

steel pier
willow scroll
steel pier
#

yes

willow scroll
#

you should also store your RectTransform as a variable

#

and checkScale is redundant

willow scroll
#

"Just make your sizeDelta to be always positive and multiply the anchoredPosition according to the pivot"

#

That's how you change your anchoredPosition regardless of the pivot

offset.x *= _stretch.x == 0 ? 0 : pivot.x + (_stretch.x > 0 ? 0 : -1);
offset.y *= _stretch.y == 0 ? 0 : pivot.y + (_stretch.y > 0 ? 0 : -1);

rect.anchoredPosition += offset;
#

where offset if the difference between previous and new sizeDelta and _stretch the direction

#

@steel pier in case you want to change the pivot

Hey, having an issue where this hit.transform.SendMessage("Hit", weapon_Tracker.weaponDamage[weapon_Tracker.currentWeapon]); is supposed to return "Hit", int 20, but it returns 2[TKey,TValue].get_Item

Use GetComponent

Then call the function on the component

simple forge
#

it wont let me, or im doing it wrong

wintry quarry
#

Definitely the latter

simple forge
#

how should i do it ?

wintry quarry
#

Call GetComponent on the object to get a reference to the component.
Then call your function on that reference

#

What does "it won't let me" mean

simple forge
#

my function is in another script

wintry quarry
#

Obviously

#

If you're having trouble with syntax you should share the code you tried and whatever errors you might be getting

Do what I said

BTW this whole question was very confusing. You should have just shared this code and your error message from the start

Likewise you can set it in the inspector and it will work too

Why did you move the variable declaration

All you had to do was rename Start to Awake

alright

I'd start by writing down exactly what you expect to happen.

I.e. click on X
X is highlighted
Press E to disable etc

And then break it down from there.

#

Right now I have no real idea how your project is structured or how you want it to work, so I can't really advise. If this is one script, or many scripts, attached to the doorknob, or all doorknobs. Why is there an array? Etc

sterile radish

i thinm that's what causing the issue

tough lagoon
#

If it's a shared script, you need to tell it what was clicked on. If it's a singular script on each doorknob, an array isn't needed and it could just directly disable whatever itself. But then pressing E is running on all copies of the script anyway, so you keep a bool to tell which one is active

thats not the issue ill send a pic

if u open pic up u can see render lines

Ideally you'll probably want something more generic and reusable, so it checks not just doorbells but all intractable objects within reach

a better way would probably to not destroy the viewer each time, and instead change the sprite or model or whatever and disable it when no item is selected. If you don't want to do that you pull the stuff inside your if statement outside and Destroy the viewer inside the if statement

Another dumb question like before, is it possible to reference a already existing game object in a prefab

languid spire
#

no

vast vessel
#

Nope

languid spire
#

only another prefab

cinder plover
#

Shit

vast vessel
#

Maybe set up a game manager that has the refrance to that object

#

Then get it in the Start method on your prefab

#

So basically when the prefab is created it asks for the game manager for the refrence

Ill try it ty

So I am importing 2dgamekit into my project and I need to know what each of these settings do so I know whether or not to let them override my project settings.
When i don't give them override permission, the textures of moving background objects and perticle effects get reduced to pink polygons. when i give them full access, i lose access to the layer dropdown in my inspector. do you guys have a brief overview of what each asset does so I can figure out if i want to import it? even like a link to the documentation or something?

hey so im still struggaling with this how do i have my enemy ai move only on the x axis because i have them able to jump and i want them to be able to move when they jump but right now if the player is above them they start flying to the player i dont want that but they still should be able to jump so i cant just lock the y axis

Use physics collision layers

Put your rpg on one layer, like "player", put the rocket on another layer like "projectile". Then disable the collision between them in project settings>physics

it will play the jump animation but if they are moving they dont jump

# amber spruce it is?

I think so. I think the problem is that your enemy isn't grounded and thats why he doesn't jump? Try adding a Debug.Log("Jump"); inside your jump method

languid gate
#

also samething happens with this code

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

public class PlayerMovement : MonoBehaviour
{
    public Rigidbody2D rb;
    public float moveSpeed;
    public Vector2 PlayerInput;

    void FixedUpdate()
    {
        Vector2 moveForce = PlayerInput * moveSpeed;

        rb.velocity = moveForce;
    }

}

``` and its like super simple so idk how the wall pushes back

could it have anything todo with the type of collider i am using?

looks like currentWeapon is null. Do you maybe have two of the scripts in your scene?

using System.Collections.Generic;

using UnityEngine.SceneManagement;
public class startGameEasy : MonoBehaviour

    public void LoadLevel()
    {

vast vessel
bitter canyon
rare basin
eager elm
# bitter canyon i have it in a "loader"

I don't know what a "loader" is? If you want to change a value from one scene to another you can use static variables:

public static spawnRate;

Then you can change it from any script without needing a reference:

EnemySpawner.spawnRate = 1.5f;

rare basin
#

that is not a good approach

bitter canyon
#

oh

vast vessel
#

What about a game manager?

rare basin
#

use a singleton, or store the spawnRate data in scriptable objects for example

eager elm
#

that's a fine approach for something like that

rare basin
#

so you can have different spawn Rate for each level

#

easily

bitter canyon
#

well theres only one level

#

i need to rename those

rare basin
#

sure but what if you want to add more levels in the future

bitter canyon
#

i dont

rare basin
#

ok xd

bitter canyon
#

its not that type of game

rare basin
#

make a DifficultyManager (singleton), set the difficulty whenever you want (store it as enum for example EASY, HARD) then in the spawner in Start() set the spawnRate based on the difficulty from the manager

vast vessel
#

Just use a singleton. Plus, you will probably need a game manager singleton script later down the road for other things

bitter canyon
#

whats a singleton?

#

i just see that it means it only creates one instance of itself

rare basin
eternal needle
eager elm
#

Singletons stink, just make the spawnRate static

rare basin
#

i've worked on many AA projects

#

in every we've used a singleton

eager elm
#

Singletons are just static variables with extra steps

vast vessel
#

Bruv didnt even know what a singleton was a second ago and is now saying singletons stink

For the paddles you do need to freeze the rotation and X position

Yes that too 😄

dense root
#

That did the trick thank you @keen dew

eternal needle
#

You may want kinematic instead of freeze position. Freezing the position can kinda mess with the collision, at least I've had issues with it. Objects think they can go further than they should into a frozen object

gilded flame
dense root
#

@eternal needle with kinematic the paddles then go through the upper and lower walls

gilded flame
#

Do those walls have static rigid bodies?

dense root
#

No, just box colliders

image.png
#

Do I add a static rigid body?

gilded flame
#

Yes, add static rigid bodies and the paddles should not go through. Fingers crossed

dense root
#

Added rigidbodies and no dice

#

And the player Inspector for reference

#

The docs say "Enabling Full Kinematic Contacts enables a Kinematic Rigidbody 2D to collide with all Rigidbody 2D Body Types. This is similar to the behavior of a Dynamic Rigidbody 2D, except the Kinematic Rigidbody 2D is not moved by the physics system when contacting another Rigidbody 2D. Instead, it behaves like an immovable object with infinite mass."

dense root
#

Even with full kinematic contacts it still goes through

gilded flame
#

Let's see... how you are moving the paddles in your script? Are you adding/removing velocity? Or directly translating the position? Were the paddles being prevented from going outside the walls when its body was dynamic?

dense root
#

rb.velocity = new Vector2(rb.velocity.x, movement * speed);

#

Yes, velocity

#

I'm gonna stick with Dynamic for now

gilded flame
#

Okay... at the very least freeze the Z rotation

The object's name is Game Manager, not GameManager

shouldn't use Find anyway

Typically the game manager is a singleton so that you can refer to it directly

or in simple cases, make a serialized field and drag the object there like with everything else

it's hard to understand half of the console errors an they usually bring me to the scripts that i know nada about

formal escarp

#

i have 2 problems. 1 is making the gun not point to the the mouse while moving, prolly camera. the other one is that when i go in bewtween gun and the player it will go the opposite way. these two combined make this game practically unplayable.

#

wait

#

got more images

#

click on the image and press left or right

#

idk what went wrong

verbal dome
#

Lol why aren't the other embeds showing

#

The PointTo script seems fine to me

red prairie
#

exactly

#

look at the video

#

like i said. click on the image. and then the arrows

verbal dome
#

I understand, just wondering why the thumbnails don't show

red prairie
#

dunno. doesnt matter currently.

#

Alright! Got it going thank you all for the debugging help :)

#

I'm unfamiliar with cinemachine, but try changing that Update to LateUpdate in case it's an execution order issue @red prairie

#

Or make sure that your code runs after cinemachine in the execution order settings

red prairie
#

its even worse. idk

slender nymph
red prairie
#

which problem?

slender nymph
#

when i go in bewtween gun and the player it will go the opposite way

red prairie
verbal dome
#

Yep, better use the character's position in the direction calculation instead of the gun's position

red prairie
#

r u reffering to this line of code?

image.png
verbal dome
#

Yes

#

Use player's transform, not gun's transform

red prairie
#

that works.

#

just spawns from the player which is kinda wierd.

#

what about the other problem. i tried setting one to eairly update. and cinamchine to late

verbal dome
dense root
#

Anyone know what is causing the following error?

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
red prairie
#

yes i used the players transform

verbal dome
dense root
#

Oh alright, thank you

verbal dome
red prairie
#

yes but how do i use the players transform for the bullet?

#

they r the exact same for both transforms

verbal dome
#

Or do the logic on the player object and reference the gun

#

Maybe it's best if you show what you just changed

red prairie
#

that still doesnt solve the issue of it not pointing to the mouse

#

all i changed was the position of the transform

verbal dome
#

Show your current PointTo script

red prairie
#

late update makes it worse

verbal dome
#

I just told you to use the player's transform instead of the PointTo object's transform here

#

Isn't the PointTo object on the child object?

red prairie
#

yes.

verbal dome
#

@red prairie Vector2 direction = mousePosition - playerTransform.position

so, i have a player object, it has a sliding() coroutine, in which it deactivates the main hitbox and activates the lower body object, which has its own, adjusted hitbox. I tried using a normal sliding() function, but making a timer for it doesn't work, as it will run entirely in the frame it was called. Is it a good idea to make a separate script for the lower body?

summer stump

weary moss
# summer stump There is a lot to unpack. Probably best to just show your !code 
public IEnumerator escorregar()
{
   //setting everything for the slide
    escorregando = true;
    hitbox.enabled = false;
    corpobaixo.SetActive(true);
    animador.SetBool("Escorregar", true);
  //duration of the slide
    yield return new WaitForSeconds(2);
  //deactivating the animation, starting a transition in the           animator window
    animador.SetBool("Escorregar", false);
  //duration the transition should be
    yield return new WaitForSeconds(0.5f);

    corpobaixo.SetActive(false);
    escorregando = false;
    nada();
}

the variables may be a little weird bc they aren't in english
nada() is a function that sets everything back to normal

summer stump
weary moss
#

no, what runs immediatly is if i make it a function, the problem with this one is that there is a period of time after everything ends that the player doesn't do anything, like it doesn't accept any input

verbal dome
#

Also make sure to start the coroutine with StartCoroutine(escorregar())

#

Instead of escorregar()

weary moss
#

i'm calling it correctly

summer stump

#

i absolutely hate writing code in native language

#

why not just english, especially when you are sharing this code in public discord

weary moss
#

i didn't plan to share it here, i'm together with another guy writing this, making the variables in native language helps me, and the other guy understand it better

summer stump
weary moss
#

i know it's hard for other people to understand the code without the whole context, so don't stress over it, i'll try a bunch of possible solutions here and report back if any of them worked

eternal needle
# weary moss i know it's hard for other people to understand the code without the whole conte...

I dont think its an issue of not understanding the code (ideally use a code site and paste more context so we can see what type each thing is), but that what you're describing doesnt make a whole lot of sense. if you called the coroutine properly, it shouldnt be running all in the same frame. I think maybe you have more code which is causing issues instead, you should add Debug.Log in your coroutine to see all of this doesnt happen right away

english is the most common to write in code, if he ever wants to find a job he will need to adapt, i doubt there is a single company (serious company) in the world writing code in native language

Guys, does anyone know why my bullets don't have the same rotation as the gun or the muzzle? var bullet1 = Instantiate(bullet, muzzle.transform.position, Quaternion.identity); bullet1.GetComponent<Rigidbody>().velocity = (targetPoint - muzzle.transform.position).normalized * shootForce;

slender nymph
#

pass the rotation of the object you want it to have the same rotation as instead of Quaternion.identity which is no rotation

unreal imp
#

ahhhhh

#

i know

#

thx

#

How would i go by checking whether the player is using controller or keyboard. Would i have to add every controller and keyboard binding to their own scheme in the input system?

quasi rose
twin bolt
quasi rose
# twin bolt Okay, i'll try searching for that.

I recall it was in one of their example scenes like when you create a new project and they come with a controller. There was a ternary line in there that checked if it was a keyboard or not. Might have been Keyboard.current

twin bolt
quasi rose
#

yup

twin bolt
#

Okay i'll try that

quasi rose
#

Looks like it's Keyboard.current and Gamepad.current

#

Could probably create some Action with that for when switching between controller/keyboard too.

twin bolt
#

I think, if the keyboard and gamepad is connected at all, then both bools will be true, i want to check what input device is sending input currently. @quasi rose

quasi rose
#

But I think current would work if you got creative with the bools and events, idk. You could track which one last had input and then update your UI or whatever you need based on an event.

amber spruce
#

how do i assign player to this in code

#

would i do smth like this ```csharp
target = GameObject.FindGameObjectWithTag("Player").transform;

so could you explain how to have it set to it

#

not sure how to do either of the things you are talking about

twin bolt
#

Why does this work when i'm navigating through my scene, but if i pause my game, it flickers back and forth between the two bools? https://hastebin.com/share/samiqujixi.rust

nothing here shows you're pausing the game

twin bolt
#

I know, this is the only code in my game that sets the bools.

#

Everything else, checks those bools.

timber tide
#

Yes but I don't know where these methods statements are located in. Methods? Update? Events?

eternal needle
# amber spruce so could you explain how to have it set to it

It all depends on how the player exists in the first place. If it's just in the scene already then dragging it in is fine. If something is spawning it, you get the object returned from instantiate and plug that into any object that wants the player. Or you use the singleton pattern (google it for unity) and access it via a static field

amber spruce
#

so the enemy is spawned in

twin bolt
# timber tide nothing here shows you're pausing the game

I think i found the culprit, In the Gamecontrols.GamePlay.Mouse.WasPressedThisFrame() it checks for input from a mouse, but i have a virtual mouse in my game, which i think is triggering it. WHich is why its flickering. How can i fix this?

timber tide
#

Still haven't answered the question

#

Are you checking through update or through events

twin bolt
#

Update

timber tide
#

If you're pausing the game, your timescale should prevent these types of updates, no?

twin bolt
#

Oh, i didnt know that.

#

Where should i move it then?

timber tide
#

I mean, there's a few ways about pausing. One is using timescale, and the other is separating game logical updates from input.

#

Actually, I don't think the event system does pause. You may be correct if you're using timescale

#

In that case you may want to add a boolean in your update (if paused then skip this input)

twin bolt
#

I ended up fixing it by using Input.getAxis instead of the new inputsystem, that detects even virtual mice. Also Time.deltaTime isnt affecting my code.

amber spruce
#

anyone know how i can check if there are no objects with a tag (trying to check if there are no enemys left before new wave)

timber tide
#

I'm just not a fan of using timescale, but if you're using rigidbodies I'd assume you are required to use it.

#

otherwise just manually disabling updates on the game logic is my solution

twin bolt
#

Thank you

rich adder
#

only on removal of enemy from list is check how many left in list

amber spruce
#

cant a list not be emtpy though

#

bro im so mad rn i just lost so much progress cause unity crashed

rich adder
amber spruce
#

aight thanks

#

bro my unity crashed again

#

it keeps crashing

rich adder
#

what kind of crash? file a bug report

amber spruce
#

it just starts not responding i dont get a error message

rich adder
#

so is it after you hit play?

amber spruce
#

yeah it plays for a few then crahses

#

it seems to happen once 5 of my enemies spawn

rich adder
#

infinite loop probably

#

what did you do to your code

amber spruce
# 
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemySpawner : MonoBehaviour
{
    public GameObject enemyPrefab; // Reference to your enemy prefab
    public Transform[] spawnPoints; // Array of spawn points
    public float numberofenemies;
    public int numberOfEnemiesInWave = 5;
    public float timeBetweenEnemies = 1.0f;
    public float timeBetweenWaves = 5.0f;

    private void Start()
    {
        // Start spawning waves
        StartCoroutine(SpawnWaves());
    }
    

    IEnumerator SpawnWaves()
    {
        while (true) // Infinite loop for continuous spawning
        {
            if (numberofenemies == 0f)
            {
            yield return new WaitForSeconds(timeBetweenWaves); // Wait between waves

            for (int i = 0; i < numberOfEnemiesInWave; i++)
            {
                SpawnEnemy();
                yield return new WaitForSeconds(timeBetweenEnemies); // Wait between enemies in the wave
            }
        }
        }
    }

    void SpawnEnemy()
    {
        // Randomly choose a spawn point
        Transform spawnPoint = spawnPoints[Random.Range(0, spawnPoints.Length)];

        // Instantiate the enemy at the chosen spawn point
        Instantiate(enemyPrefab, spawnPoint.position, spawnPoint.rotation);
        numberofenemies++;
    }
}

thats the code i changed i believe

#

i dont think i changed anything else

rich adder
#

also this is a bad way to do this anyway

#

again you should just keep track wit a list

#

Instantiate returns the enemy spawned

amber spruce
rich adder
amber spruce
#

anywhere or at the end or smth

Does x > 0 returning false imply x <= 0, or ONLY x < 0?

x is a float

# rich adder inside the while loop

also any idea why this barely launches the enemy but when they are above me it launches them super high

void LaunchTargets()
{
    // Find all objects with the specified tags within the specified radius
    foreach (string tag in targetTags)
    {
        Collider2D[] targets = Physics2D.OverlapCircleAll(transform.position, affectRadius, LayerMask.GetMask(tag));

        // Launch each target that is not the current object
        foreach (Collider2D target in targets)
        {
            if (target.gameObject != gameObject)
            {
                Rigidbody2D targetRb = target.GetComponent<Rigidbody2D>();

                if (targetRb != null)
                {
                    // Calculate the direction from the launcher to the target
                    Vector2 launchDirection = target.transform.position - transform.position;

                    // Apply force to launch the target
                    targetRb.AddForce(launchDirection.normalized * launchForce, ForceMode2D.Impulse);
                }
            }
        }
    }
}
#

i have tried setting launch fordce higher doesnt fix much

Hi friends!
I'm using this line in attempt to basically find the net angle of input if that makes any sense:

Mathf.Atan2((Input.GetAxis("Vertical"),Input.GetAxis("Horizontal"))) * Mathf.Rad2Deg

But unity disallows me stating:
" CS7036 There is no argument given that corresponds to the required formal parameter 'x' of 'Mathf.Atan2(float, float)" "
Does anyone know how to make it accept my values?

verbal dome
#

So it thinks you are giving it just one variable, more specifically a tuple (float, float)

thin carbon
#

All that time wasted to such a silly mistake!

#

I never would of caught it myself, thx a lot for the help 🫶

How do I measure something in Unity? For example if I wanted to replace the paddles how would I know what size?

image.png
#

Like if I wanted to replace them with custom sprites I made in Aseprite, how would I know what size?

slender sinew
#

Go to the scene view and turn on the grid. Each unit grid cell is one unit, and you can decide how many pixels that should be.

#

If those are just squares that you scaled, you can also just check the scale

dense root
#

Oh I see so just judge based on the scale
