only if im not holding shift though right?

modest dust
#

GetKeyDown detects the moment a key gets first pressed

#

You want GetKey for continuous detection

sand snow
#

ohhh okay thank you

modest dust
#

But keep in mind that with your current code you'll get a massive speed boost in a matter of a few frames

sand snow
#

yeah that just happened, and it just keeps multiplying until infinity

modest dust
#

If it's a one-time speed boost only then consider either getting rid of *= and just define a constant sprintSpeed somewhere in your code and assign it rather than multiply it or look into GetKeyDown and GetKeyUp

languid spire
#

you want GetGey, not GetKeyDown

sand snow

modest dust
#

Basically:

if (shouldSprint)
   currentSpeed = some_sprint_speed;
else
   currentSpeed = some_normal_speed;
modest dust
sand snow
#

oh I see

modest dust
#

So, once again, I suggest taking a C# course, because you seem to be lacking some basics and these are the root of your issues

sand snow
#

are the ones on Unity good?

#

like the unity learn website

modest dust
#

Take a pure C# course first

#

There's a link in the pinned messages in this channel

sand snow
#

is it free?

modest dust
#

Under Resources, Beginner, Intro to C#

#

All the pinned resources are free as far as I'm aware

sand snow
#

oh okay thank you so much 🙏

#

and by the way my sprint now works!

sand snow
#

okay i ran into another problem...

# 
if (rb.velocity.x >= 0f)
{
    facingRight = true;
}
else
{
    facingRight = false;
}
#

i am trying to make a bool to see of I am facing left or right, which kinda of works

#

but if i click the left movemnt button it does say im facing left but then when i let go it reverts to facing right

#

i want it to keep looking left unless i press the right movement key again

#

i am trying to make a wall check once i make the bool so that if i am running into a wall my velocity on the x axis can no longer go that direction

#

is it not working because i am using velocity instead of something else

queen adder
#

Velocity tells you how fast is the rigidbody in the World Direction. You should choose which direction will be considered as Right. For example, local right (transform.right)? World right (Vector3.right)?

sand snow
#

ohhh okay i will try that right now i didnt know that was possible

#

this doesnt work either though, its saying "cannot implicitly convert type 'unityengine.vector3' to bool"

if (transform.right)
{
    facingRight = true;
}
else
{
    facingRight = false;
}
#

my game is 2D i forgot to mention if that matters at all

queen adder
sand snow
#

oh then cant i use Input.GetAxisRaw("Horizontal") for that?

queen adder
queen adder
sand snow
#

i accidentally click f10 while scripting and it did something

queen adder
#

But if you do that:
if (1 < 3)
Then it will be valid.
That means:
if (Input.GetAxisRaw("Horizontal") < 3)

i have this button, even if i click it nothing happens
the code is:

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

public class SceneManagerScript : MonoBehaviour
{
    public void LoadScene(string SceneName)
    {
        SceneManager.LoadScene(SceneName);
    }
}```
image.png
#

the onlick event seems right to me

image.png
#

also the build settings

image.png
sand snow
#

@queen adder i was able to solve my problem

#

i made a string variable "lastDirection" and used GetKeyDown to determine if my "facingRight" bool is true or false

#

so if my velocity.x was equal to 0 (meaning im pressing nothing) that my bool = lastDirection =="right"

#

heres the code:

private string lastDirection;

void Start()
{
    lastDirection = "right";
}

void Update()
{
 if (Input.GetKeyDown(KeyCode.D))
 {
     facingRight = true;
     lastDirection = "right";
 }
 else if (Input.GetKeyDown(KeyCode.A))
 {
     facingRight = false;
     lastDirection = "left";
 }
 else
 {
     if (rb.velocity.x == 0)
     {
         facingRight = lastDirection == "right";
     }
 }
}

i have a question: is there a better way to generate Random.InUnitSphere or OnUnitSphere within a parallel.for or parallel.foreach loop

#

because they usually return that they can only be run on the main thread

Okay I think I'm making progress on this rock spawning thing.

https://hastebin.com/share/irolitiyop.java

Everything is working fine, except that my height check is kinda messed up and I don't understand why.

In the code, maxYPosition is set to 3, and minYPosition is set to 1, so I'm not really understanding why my rocks are spawning below 0 on the y. 😕

Can anyone see my mistake please? Been staring at it for too long. lol.

You could code the normalization by yourself and when length = 0, return (0,0,1) (almost inpossible to happen so shouldn't affect the overall distribution) or pick new coordinate. Unitys normalize method returns Vector3.zero for zero length inputs which might cause issues depending on your case

ive been working on this fluid simulation, looking at the papers i applied the equations, but when two particles got in the same position they combined so i needed a random pressure force to push them away

#

instead of just returning zero

night valve

Strange that unity does not provide build in SpherePoint struct for operating on polar coords, they can be really handy. Or does it? Anyways making such struct yourself is quite easy

I am making a script to flip my character depending on which direction im facing, I have a working system to check which direction im walking, but my player only flips if I click A instead of A and D, if i click D my player doesnt flip but just moves with the player facing whatever way A set it to can someone please help

night valve
#

you need to provide code for someone to help you

sand snow
# 
     if (Input.GetKeyDown(KeyCode.D))
     {
         facingRight = true;
         lastDirection = "right";
         Flip();
     }
     else if (Input.GetKeyDown(KeyCode.A))
     {
         facingRight = false;
         lastDirection = "left";
         Flip();
     }
     else
     {
         if (rb.velocity.x == 0)
         {
             facingRight = lastDirection == "right";
         }
     }
 }
 
 private void Flip()
 {
     if (facingRight)
     {
         transform.localScale = new Vector2(transform.localScale.x, transform.localScale.y);
     }
     else if (facingRight == false)
     {
         {
             transform.localScale = new Vector2(-transform.localScale.x, transform.localScale.y);
         }
     }

 }
 
 }
#

there is the code, sorry

#

there are 0 warnings and 0 messages, so the code is technically correct, but my player doesnt flip when I click D

night valve
#

also you can try swapping A with D behavior and see in the inspector if scale is set to negative, didnt do much 2D, but negative scale can mess things up in 3D, so maybe 🤷

ruby python
#

Sorry my answer was all over the place. lol. Gimme a sec.

You should be able to modify this to fit. I use this snippet to switch between firing left gun and right gun.

if (leftLastFired == true)
            {
                Instantiate(bulletPink, firingPointRight.position, firingPointRight.rotation);
                StartCoroutine(MuzzleFlashLight(leftLastFired));
                leftLastFired = false;
            }
            else
            {
                Instantiate(bulletPink, firingPointLeft.position, firingPointLeft.rotation);
                StartCoroutine(MuzzleFlashLight(leftLastFired));
                leftLastFired = true;
            }
#

Not sure how it works with 2d though tbh.

sand snow
#

I already tried changing it to work with the "lastDirection" string, it still does the same thing

#

do you thinkit would work if I do something like this:
if(rb.velocity.x > 0)
{
Flip()
}

night valve
#

then it will Flip() every frame if there is any velocity

#

if it is in update()

sand snow
#

i just tested it it doesnt do that but I still have the same problem

ruby python
#

Debug your bool and your localscale.x (or serialize them)

night valve
#

also your Flip() method is named improperly i think. Flip is to... well flip. No matter which direction. So it should be just

void Flip(){

             transform.localScale = new Vector2(-transform.localScale.x, transform.localScale.y);
}
sand snow
#

thats how it is

ruby python
#

Actually yeah, that above will just invert the current local scale, so you don't even need the bool.

sand snow
#

but if there is no bool, then how will it know which direction I am facing

night valve
#

do it outside the flip, check if direction changed, if it changed - do Flip(), otherwise dont

sand snow
#

im about to test it with out the private void, is that what you mean?

night valve
#

it doesnt matter

sand snow
#

yeah I just tested it, I thought this would happen, but my player now flips over and over no matter what

night valve
#

what i mean is:

string lastDirection = "right";
void Update()
{
  string newDirection;
  if(Input.GetKeyDown(KeyCode.A){ newDirection = "left";}
  else if(Input.GetKeyDown(KeyCode.D){ newDirection = "right";
  }
  else {newDirection = lastDirection;}
  if(newDirection != lastDirection) {Flip();}
  lastDirection = newDirection;

}


void Flip(){

             transform.localScale = new Vector2(-transform.localScale.x, transform.localScale.y);
}
#

probably it could be done better, but at least it is readable imo

sand snow
#

let me try it

night valve
#

(#edit - added semicolons)

sand snow
#

nothing happens

#

yeah nothing happens, i even copy pasted it

night valve
#

Add debug logs to print new direction and last direction when the key is pressed

#

Also debug.log "flipping" in flip method, basically debug log is your friend when anything does not work as expected

#

Also you can get rid of else statement, and set string string newDirection = lastDirection on the first line of Update, but this will probably not change anything, just make code cleaner

#

go to 3:40 to see the method

#

the problem with my code before, is that the bool wasnt being used to detect if I was actually fdacing left or right, therefore I could flip infinitely

#

also im sorry if I am not allowed to put links

#

is that allowed?

verbal dome
#

@sand snow i can see 5 hours of questions from you. Maybe make a thread

sand snow
#

i got the solution

#

sorry about that ill try to start remembering, please forgive me if I forget

lapis frigate
#

umm any1 can give me a direction to how do I create a level system for an rpg game?

eager spindle
#

do you have any plans on what your levelling system is like?

lapis frigate
#

1v1 turn based combat system

eager spindle
#

What will the player do to level up?
What will the player gain from levelling up?
What will be displayed when the player levels up?

#

Do think of more questions you can break down before making this

lapis frigate
#

What will the player do to level up? defeat enemies
What will the player gain from levelling up? his stats like dmg, defence, health ect will level up
What will be displayed when the player levels up? just like standard level up messege with maybe some infomation on what happened

#

I mean I'm not looking for something too complicated just like asking if I need a seperate maneger for it or do I need to do it in the players script

eager spindle
#

Ohh

#

Make a seperate manager

lapis frigate
#

ok and what do I do there? do I not put any information about the levels in the player's script?

#

for example the current exp max exp level ect?

eager spindle
#

To be honest it's up to you

lapis frigate
#

ye ik but like im just asking for the better way to do it

eager spindle
#

But I prefer to have one responsibility per class, like player combat and player movement has its own scripts

true oriole
#

im tryna enable the moving speed under my script

Screenshot_2024-09-26_174006.png Screenshot_2024-09-26_174024.png

So ideally you keep your RPG levelling in it's own script too

In addition to your error, you should not multiply mouse input with deltatime

{
   double e=System.Data.Convert.ToDouble(System.Data.DataTable().Compute(CurInput,"");
   CurInput += val;
   textdisplay = CurInput;

}
}
public void Update()
{
public string CurInput="";
string val="4+15+63";
}

and when i press the button, it displays CurInput as NULL string, not updating itself. Although, it is updated when i press twice, but the error is still displayed:- "Cannot assign double values to DBNull"

Hey guys I'm making a dungeon like room generator, it's just hallways and stuff. I need to do occlusion of course for this because it's huge, but normal occlusion doesn't seem to work at runtime. Is there any way I can get help with this, it's the most important part of my game.

verbal dome
shy ruin
verbal dome
#

Or program some sort of "portal-based occlusion" yourself

#

Which I think would be the simplest way to implement it

shy ruin
#

Long hallway made out of multiple rooms

verbal dome
#

That's not an issue if you implement it correctly

shy ruin
#

This is weird, does it look like it's working?

#

It just started doing this

#

It seems to be only FOV though.

#

Biggest problem is it cannot be an occluder

verbal dome
#

Yeah I don't think that the built in occlusion is suitable for procedural stuff

#

I'm in the middle of writing my own occlusion system for generated areas. If you find something useful please ping me though @shy ruin

shy ruin
#

Ok, what should I do right now though.

verbal dome
shy ruin
#

Fine, I'll try it but the reviews say there's a ton of deprecated variables.

verbal dome
#

Fixing those would likely be easier than writing your own from scratch. I havent' found any alternatives yet

shy ruin
ripe oyster
#

in visual studio it sometimes gets the references and has the autofill, but now i opened a second new script and it doesn't detect any of the unity systems. not even debug.log();
does anybody know what can cause this?
so far there are 2 scripts in this project. 1 works fine, the other doesn't.

shy ruin
#

The only thing left is your portal method, any way you could point me in the direction to understand it and get working on it?

verbal dome
#

It's some pretty advanced stuff though, definitely not a beginner subject

#

@shy ruin Looking at the video series I linked it seems really complex, even for me (going into SIMD stuff etc.)
But keep searching for solutions, especially portal-based, since that should work the best for closed spaces like dungeons

shy ruin
verbal dome
#

Using cameras and custom shaders is a possibility yeah. There might be some big issues I can't think of right now

shy ruin
verbal dome
#

Btw frustum culling doesn't really help you here. An area can be in the frustum but still be occluded by a wall

#

I'd probably render the camera to a rendertexture with certain colors representing certain areas. Then use a script or a compute shader to check if an area's color is visible in the texture

hi! im making a 2d maze game in Unity for my comp sci coursework and its been working fine so far, however, after i created the playerEnemyCollision script for my game and ran the program, a few errors came up.

  1. the hearts/lives disappear from the screen (i added this as a sprite rather than ui)
  2. when i dont move the player, the enemy characters move/push the player outside the screen on its own
  3. in the console, it does not report "Game over" when the enemy and player collide.

here is my PlayerEnemyCollision script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerCollision : MonoBehaviour
{
private void OnCollisionEnter2D(Collision2D collision)
{
if (collision.transform.tag == "Enemy")
{
Debug.Log("Game Over");
}
}
}

here is my lives manager script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class LivesManager : MonoBehaviour
{
public static int lives = 3;
public SpriteRenderer[] hearts;
public Sprite fullHeart;
public Sprite emptyHeart;
private void Awake()
{
lives = 3;
}
// Update is called once per frame
void Update()
{
foreach(SpriteRenderer heart in hearts)
{
heart.sprite = emptyHeart;
}
for (int i = 0; i < lives; i++)
{
hearts[i].sprite = fullHeart;
}
}

Hey, I made a basic cc (rigidbody), and for some reason it seems to be very choppy, you can see the tree in the left, and every child and parent is on scale 1 and the camera is a child of an empty which updates to the position of an empty on the player called cameraPos. Help is appreciated.

You'll have to show the code

but why is the camera not directly a child of the player

I have an object that has a collider set as a trigger with a script that checks for OnTriggerEnter, which works, however if any other trigger is being activated, it executes this too
How can I restrict this OnTriggerEnter to that one BoxCollider?

This doesn't have the code that moves the camera. But I suggest you just make the camera a child of the player if the only reason it's not already there is to avoid lag

toxic void
#

Alright, thanks

#

It didn't fix the issue. By the way, the stuttering only happens when I move my camera and move at the same time. It also happens but only a little bit when moving only the camera, so moving might just be amplifying it.

#

So here's the camera movement script:

public class CameraHandler : MonoBehaviour
{

    public float xSensitivity;
    public float ySensitivity;

    public Transform playerTransform;


    float xRotation;
    float yRotation;

    // Start is called before the first frame update
    void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }

    // Update is called once per frame
    void Update()
    {
        float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * xSensitivity;
        float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * ySensitivity;

        xRotation -= mouseY;
        xRotation = Math.Clamp(xRotation, -90f, 90f);
        yRotation += mouseX;

        transform.rotation = Quaternion.Euler(xRotation, yRotation, 0);
        playerTransform.rotation = Quaternion.Euler(0, yRotation, 0);
    }
}

The OnTriggerEnter has a collider parameter, I think it has a tag property.

stiff crag
#

Yeah, and I can check what has collided with the trigger, however the other collider isn't the issue
Currently any trigger I touch with the other collider calls the event, somehow

2d vector in my case

verbal dome
#

You can use Mathf.Sin and Mathf.Cos and then multiply the vector with the magnitude

#

Oh and Mathf.Deg2Rad assuming you want to use degrees not radians

#

Or ditch the trigonometry and do Quaternion.Euler(0, 0, angle) * new Vector2(0, magnitude)

stiff crag
# toxic cloak https://docs.unity3d.com/ScriptReference/LayerMask.html

Isn't this for including/excluding colliders? The issue is not that the wrong collider calls the event, but that in area, where are multiple triggers and there is 1 with this script, although if the collider enters any trigger (no matter if the trigger has or not the script) the event gets called

#

Ex. Trigger1 with the script, Trigger2 without the script
If collider named "player" enters Trigger1, the event gets called, but somehow, if the same collider enters Trigger2, the same event gets called, even though the Trigger2 doesn't have the said script

Use Awake/Start for initialization instead

tender stag
#

is it possible to make your own attribute which would expose the variable in the editor

#

but make it read only?

#

so you couldnt assign anything by dragging or clicking

#

you would only be able to assign it through script

If you using something like NaughtyAttributes it has a ReadOnly attribute for that

# rancid tinsel im looking at inheritance rn for uni but im struggling to see a good example for...

Make a script - "Weapon". Has things like damage, durability, whether it's one or two handed, etc.
Then you could make a thousand scripts - "Baseball bat", "Chainsaw", "Park bench", "Cash Register", etc. that all inherit from Weapon.

Your inventory becomes List<Weapon> and your current weapon is a variable of type Weapon and you can very easy do something like duraText.text = currentWeapon.durability without even caring about which of those thousand child objects you currently have in that slot

is rotation 0-359? as a quaternion, like the y value of a quat

The y value of a quaternion has nothing to do with the Y axis of normal Euclidian space, it's a normalized 4D value including imaginary numbers to express an orientation

#

Yeah, you can't use an expression as a switch case. The only way this would be valid is if buildRot was a const, which is what I meant by "technically true"

mighty compass
#

Ah I see

polar acorn
#

and you can combine X and Z rotations to gain the same orientation you could by having a value on Y

mighty compass
#

coolio

#

What does rotation even return then if not 90, 180 etc

#

is it like some random float value

polar acorn
#

If you ever find yourself trying to deal with individual components of a quaternion, don't

mighty compass
#

I see hahaha

#

I have to limit the rotation of these wall assets I've made, so they place correctly in a grid block

#

dependent on player rotation to grid space they're placing it in

#

euler angles would be waht I want to use then?

polar acorn
#

Generally, you should work with directions rather than angles. You can get the direction it starts facing, and compare it to a world direction. Dot product is 1 when the two directions are facing the same direction, 0 when perpendicular, and -1 when opposite. So, you can get the current forward direction, and compare it to Vector3.forward, Vector3.left, Vector3.backward, and Vector3.right. Find which one has the highest Dot Product, that's the direction the object is "closest to" facing

#

That way you don't have to deal with positive/negatives, or non-Y rotations expressing the same direction

mighty compass
#

Awesome, thankyou. That's great

is it better to write your own inputs for movement with character controller or simply use the input manager

#

im about to just throw out the entire movement script and start over because i feel like with the way i've written it i cant really add crouching or jumping. originally i had no intentions for those because it didnt really cross my mind as that important. i likely wont do the jumping, but crouching will likely be added

#

physics vs character controller
my greatest enemy

I´ve been struggeling the past hour with the following problem:

I made some code in a flappy bird clone to add a point every time I go trough a trigger between pipes. Works perfectly

Now I want to make it so that if I get a game over I cant get more points even if I still go trough another pipe, but no matter what I do the points either stay at 0 the whole time or the code dosen´t work at all.

WHat should I do?

aat the bottom,

deft grail
valid turtle
#

yes that code I sent runs pefectly

deft grail
#

ah

#

nvm

#

i see the problem

deft grail
#

you are just checking if your script variable is true

#

your not checking the actual bool itself

marble hemlock
#

i might just throw out my script and character controller and work with rigid bodies instead

#

never really done it before so this might be a pain

valid turtle
deft grail
deft grail
#

the . access a property

valid turtle
#

Do I put that after the && ?

deft grail
valid turtle
#

I get CS0117

Basically MyBool dosent have a reference. But if I change MyBool to what I called the alive status then it becomes CS0120

marble hemlock
#

ye i'll just set the player to be a kinematic rigid body and code the movement

deft grail
valid turtle
# 
 private void OnTriggerEnter2D(Collider2D collision)
    {

        if (collision.gameObject && SChloppyScript.SchloppyLebt == true)
        {
            logic.addScore(1);
        }
    }
}
marble hemlock
#

the player itself is not what needs to be affected by physics, but the player's movements will be applying physics effects to other objects it interacts with

#

so if it runs into something (that also happens to be a rigid body that isnt kinematic), it should push that thing

#

how fun :(

deft grail
valid turtle
# 
public SChloppyScript SchloppyLebt;
#

isnt that the reference?

deft grail
#

in this code

ashen frigate
#

im trying to add an partical effect and after 1 use it gets destroyed do u know how to fix it ?
MissingReferenceException: The object of type 'ParticleSystem' has been destroyed but you are still trying to access it.

}

//Other Script
public MyScript myScript;

deft grail
#

what you should do is just de activate it, or Instantiate and play one instead of playing the same one

#

by making a prefab and instantiating and playing it

deft grail
valid turtle
#

give me a bit

marble hemlock
#

i was panicking and worrying id have to redo the entire thing and replace all the components but turns out i can just remove the character controller component UnityChanThumbsUp

valid turtle
#

The problem I have is that it says it needs an object reference, but I have that reference like I said b4. Im so confused

deft grail
#

what you have done basically is:

public MyScript MyBool;
if(MyBool)
``` which is wrong, the compiler doesnt just guess you want to use `MyBool` of `MyScript` because you named your variable that
valid turtle
# 
/// I have this
  public SChloppyScript SchloppyLebt;

/// and I try this
SChloppyScript.SchloppyLebt == true)
deft grail
valid turtle
#

Ohhh okay

deft grail
# valid turtle Ohhh okay

this line public SChloppyScript SchloppyLebt; can be named absolutely anything, it doesnt relate to just 1 variable you want to access from it, you TELL it what variable you want to access via the . then typing the name of the variable you want

valid turtle
# 
  if (collision.gameObject && SchloppyLebt.SchloppyLebt == true)
        {
            logic.addScore(1);
        }
        else
        {
            logic.addScore(0);
        }
      
    }
}
#

this might work then?

deft grail
valid turtle
#

Okay now its just not adding score at all anymore

#

Wth

#

xD

deft grail
valid turtle
#

yes

marble hemlock
#

i added the component to begin with

deft grail
# valid turtle yes

before the if statement do Debug.Log($"Collided with: {collision.gameObject.name}, bool is: {SchloppyLebt.SchloppyLebt}");

#

and see what it prints

valid turtle
#

NullReferenceException: Object reference not set to an instance of an object

deft grail
#

i assume not

valid turtle
#

Uhh wdym by that

deft grail
valid turtle
#

you mean here

deft grail
#

no

#

on the other script

#

MiddeloPipScripto

#

which isnt on this game object

valid turtle
deft grail
valid turtle
#

Yes

deft grail
#

then go to that game object

valid turtle
#

okay

#

I did

deft grail
#

now there should be an empty slot

valid turtle
deft grail
#

oh right its a prefab

#

so you wont be able to drag it in

valid turtle
#

jup

deft grail
#

but Find should be avoided as much as possible usually

valid turtle
#

Where should I use find?

deft grail
#

the same way as you do multiple times already

valid turtle
# 
void Start()
    {
        logic = GameObject.FindGameObjectWithTag("Logic").GetComponent<LogicoScripto>();
    }
#

like here

deft grail
#

yeah

#

but for SChloppyScript this script instead

valid turtle
#

what would the code look like? I never wrote a find function

deft grail
#

i see multiple of them

#

in your code

valid turtle
#

Sorry Im just so new to this. What do you mean by find?

cosmic dagger
deft grail
#

or if it has a tag you can use the FindWIthTag

valid turtle
#

That probably wont work, because I added a tag to that gameobejct

#

Everything will not work if I do that I think

deft grail
#

your just finding a game object by name

#

then accessing the component from it

valid turtle
#

Im so confused as well

deft grail
valid turtle
#

I know Im sorry

deft grail
#

as simple as that

valid turtle
#

I put that into start

#

that whole thing

deft grail
#

yes

#

its just 1 line, "that whole thing" sounds a bit exaggerated lol

valid turtle
#

To me it looks so confusing because I barely understand what it means so I call it "that whole thing"

crimson whale
#

Not sure if this is a code issue, so please don't jump down my throat. I don't know which channel to post this in.

I have a prefab containing a parent "Struct_Cannon" with no mesh attached to it, and two children. One a cube and one a cylinder.

When I instantiate the prefab, the cube does not come along, and simply isn't present.

Nothing gets deleted until the structure has less than 1 health, and here's the instantiation code:

    if (!spawnedStruct) {
        GameObject curCannon = Instantiate(cannon, new Vector3(0, 0.5f, 0), Quaternion.identity);
        StructInitiate structInitiate = curCannon.GetComponent<StructInitiate>();
        structInitiate.structActive = true;
        structInitiate.health = 200f;
        spawnedStruct = true;
    }
    else {
        Debug.Log("Cannot place: cannon in way");
    }       
}```

The body child is active and on a plane the camera can see, but it's not being added to the scene at all.

Any help is greatly appreciated.

But why "YourObjectNameThatHasThe (SChloppyScript)"?

why SChlopyScript

idk what you name it

Schloppy thats what you name it

SchloppyLebt = GameObject.Find("Schloppy").GetComponent<SChloppyScript>();

Wait I think I understand my mistake

#

Do i put it Voidstart of the Bird script or the trigger script?

deft grail
valid turtle
#

oh

#

lmao

deft grail
#

the bird script is already the bird script

#

why would it find itself

valid turtle
#

I was like;
why would I find it where I already am

# 
void Start()
    {
        logic = GameObject.FindGameObjectWithTag("Logic").GetComponent<LogicoScripto>();
        SchloppyLebt = GameObject.Find("Schloppy").GetComponent<SChloppyScript>();
    }
crimson whale
#

Hey @deft grail you see any immediate issues with what I'm doing? Can't figure this out

valid turtle
#

like this

#

or remove the first line?

deft grail
deft grail
crimson whale
#

But the cube just isn't being included in instantiation

valid turtle
deft grail
#

this is why Find isnt good either, because if you rename it boom the code is broken

valid turtle
#

So what I need to find is actually:

"SchloppyLebt" right?

#

for the isAlive code

deft grail
valid turtle
#

yes

deft grail
#

you cant find the bool, but you can find the script

#

thats your goal yes, find the script

valid turtle
# 
SchloppyLebt = GameObject.Find("SchloppyLebt").GetComponent<SChloppyScript>();
#

like that

#

I think

crimson whale
#

Found the issue: I had the script intended for the prefab as a whole attached to the child object.

deft grail
valid turtle
# 
void Start()
    {
        gameObject.name = "Schloppy";

or something along those lines.

well either way, there you go thats the problem

heady sleet

I know

valid turtle
deft grail
heady sleet
#

I have my subject!

deft grail
# heady sleet

if your talking about modding "bean", then dont.
modding isnt allowed in this server lol

valid turtle
deft grail
#

just make your own game

#

not sure what the point of modding games is anyway

#

some random games

valid turtle
#

But a bool dosent have a value. Its only true or false no?

deft grail
#

your finding and setting a script, not a bool

valid turtle
#

because we were trying to fix that I couldnt stop getting either 0 points or 1 point even if the bird is ded

#

and I tried that with a bool

deft grail
#

yes because you were trying to get the bool from thin air

#

you need to get it from your actual instance of your script

#

which is what you did by making a variable and setting its value to an instance of the script

valid turtle
#

Okay but this:

SchloppyLebt = GameObject.Find("Schloppy").GetComponent<SChloppyScript>();
#

isnt reference the bool?

deft grail
#

its referencing the script

valid turtle
#

yes

deft grail
#

to reference the bool directly itself

valid turtle
#

OHHH

deft grail
#

but if you do it once in Start that wont help anyway

valid turtle
#

Sorry I cant read

#

I forgot the beginning part of SchloppyLebt

#

so I was like

#

how are we getting a value for the bool if we arent talking about the bool anywhere

deft grail
deft grail
#

only in the if statement

valid turtle
#

But SchloppyLebt is the bool no?

public bool SchloppyLebt = true;
#

So if we do this:

        SchloppyLebt = GameObject.Find("Schloppy").GetComponent<SChloppyScript>();

we are talking to (or about) the bool

deft grail
#

you can name it whatever you want

#

it wont change a thing

valid turtle
#

okay now I understand nothing again

#

One sec

#

I might understand it

deft grail
valid turtle
#

So the problem started here:

 if (collision.gameObject && SchloppyLebt.SchloppyLebt == true)
        {
            logic.addScore(1);
        }

I wasnt using
SchloppyLebt.SchloppyLebt

But instead SChloppyScript.SchloppyLebt

So we made this:

SchloppyLebt = GameObject.Find("Schloppy").GetComponent<SChloppyScript>();

But if this 2nd line of code dosent have anything to do with the bool, why did the 1st line now know what to do?

deft grail
valid turtle
#

right

#

and?

#

we need the 2nd line so that what happens?

#

Im so stupid ngl

deft grail
#

so SchloppyLebt = GameObject.Find("Schloppy").GetComponent<SChloppyScript>(); or public SChloppyScript SchloppyLebt;
have nothing to do with your bool

#

these just reference the SCRIPT

valid turtle
#

yes

#

So if I ever do something like this agian, I would need both

public SChloppyScript SchloppyLebt;

// and

        SchloppyLebt = GameObject.Find("Schloppy").GetComponent<SChloppyScript>();

to make points only appear when the character is alive

because the public line isnt enough of a reference

deft grail
#

what you can also do is

valid turtle
#

in the inspector it is only a checkbox

image.png
deft grail
# 
//In your SChloppyScript

public static SChloppyScript Instance;

void Awake()
{
  Instance = this;
}

and in your trigger script do SChloppyScript.Instance.SchloppyLebt == true

deft grail
valid turtle
deft grail
valid turtle
#

AHhh

#

okok

deft grail
#

or what you did with a Find

#

or assign the variable when you Instantiate the pipe

valid turtle
#

okay

#

So just for future proofing

#

why is finding not good?

deft grail
#

and because theres better ways of assigning a variable

valid turtle
#

okay

deft grail
#

the best one would be when instantiating it

valid turtle
#

But thats impossible if I like make something, then decide to add something else, then I have to delete the first thing and remake it so the 2nd things works perfectly?

deft grail
#

add what

#

depends what your adding and changing?

#

idk

valid turtle
#

I wanted to create a FlappyBird clone

So I made the basic game with jumping, pipes and game over

To make the pipes I make a prefab so it dosent infinetly creates pipes

Then after Im basically done I want to add a Score system.

But to not use find I would need to delete the prefab and recode the pipes so I could properly add the scoresystem to avoid find

deft grail
#

you just need to change the way you reference

valid turtle
#

because you said I cant reference to a prefab

deft grail
#

a prefab cant reference scene objects yeah

deft grail
valid turtle
#

Okay

#

I think I will just leave this how it is. I think I half understood what you kindly tried to explain to my stupid monkey brain.

We fixed it and I can move on to the next addition for the game haha

deft grail
#

for your first or even second or even 10th project if they are all small/prototypes
then bad code doesnt really matter

valid turtle
#

Using the bool value: The boolean SchloppyLebt.SchloppyLebt is part of the SChloppyScript. If you don’t assign SchloppyLebt to the right object using GameObject.Find and GetComponent, the script wouldn’t know which instance of the SChloppyScript you're referring to, making it impossible to check its SchloppyLebt value.

This is what ChatGPT spat out.

Now I get it

deft grail
valid turtle
#

Like how does it know which component to fetch if we didnt specify

deft grail
valid turtle
#

oh so

deft grail
#

then it errors

valid turtle
#

The two lines of code would only work togehter

#

never alone

deft grail
#

thats it

#

or if you use ONLY the 2nd line also, would work

valid turtle
#

because it only knows to fetch .schloppylebt by needing it for the point adding

valid turtle
deft grail
#

by the 2nd line you mean the one with Find correct?

#

thats what i mean at least

valid turtle
