#

dont see why it would be tho

#

worst case scenario you just make multiple fixed timesteps

#

you can use a faster one for this

#

if you need a super slow one for something else

verbal dome
rocky wyvern
#

since you are using fixedupdate you should use impulse or velocitychange force modes

#

using default in fixedupdate will result in very small velocity change

#

I think?

torpid igloo
#

yep

#

works now

#

thanks everyone

swift crag
#

Impulse and VelocityChange apply an instantaneous change in momentum or velocity

#

You're meant to use these for things like jumping

# 
if (doTheJump) {
  rb.AddForce(Vector3.up * 10, ForceMode.VelocityChange);
}
#

This is basically identical to

#

rb.velocity += Vector3.up * 10;

#

If you use these two force modes in every single fixed update call, you'll get 50 times more force or velocity change than you expected

# 
void FixedUpdate() {
  rb.AddForce(Vector3.up, ForceMode.VelocityChange);
}
#

This will accelerate you by 50 meters per second every second

# 
void FixedUpdate() {
  rb.AddForce(Vector3.up, ForceMode.Acceleration);
}
#

This will accelerate you by 1 meter per second every second

swift crag
#

It's wrong, but at least it's wrong in a framerate-independent manner 😉

#

It would be very wrong if you did that in Update, because then the amount of acceleration would depend on your framerate

rocky wyvern
#

I thought force was scaled by deltatime?

#

What’s the point of them even existing if they’re done by fixeddeltatime then

wintry quarry
rocky wyvern
#

Um yes I’m saying the force and accel modes are just like

#

Velocity change * 0.02 or whatever ur fixed step is at

#

Surprised they even exist if that’s the case is all

wintry quarry
#

Acceleration is so you can literally write the amount of acceleration you want in sensible units and it just works

#

Force is so you can literally write the force you want in newtons and it just works.

#

Acceleration is m/s^2

#

Force is in Newtons

#

It's possible to achieve the same result with any force mode but these are convenient for simplifying the math

cosmic dagger
#

Force and Acceleration apply x amount of force over time
Impulse and VelocityChange apply x amount of force during the one frame . . .

#

Those dropdowns are just shortcuts for adding and removing behaviours. Setting it to None just destroys the CinemachinePositionComposer behaviour, so that's what your code would need to do. However, that is not the recommended way to use Cinemachine. Instead, create a second CinemachineCamera without the PositionComposer and activate it.

i have a problem where script is working when i out game object manually in the hierarchy. but when i try to instansiate it it doesnt work/ i have checked prefab and the gameobject is same

#

did you click the links sent to you

#

click VS Code

#

double check each step is taken care of

long jacinth
#

it is

rich adder
#

well obviously something is wrong. Close VSCode, go to external tools in Unity and click Regen Project Files button. Open script again by double click in unity

check for errors in vsc

and the problem

rich adder
ancient karma
#

Quick question, I was hoping to detect a null reference for a condition (if this doesn't exist yet, do something else first). Is there any way I can write a condition that evaluates that?

swift crag
#

you can compare any reference type to null

# 
if (foo == null) {

}
#

additionally, any Unity Object can convert into a boolean, so you can do

# 
if (foo) {
  // it's a valid Unity Object reference
}

if (!foo) {
  // it's invalid
}

lol - why did you hide which external editor you have set in Unity? 🙂

rich adder
# long jacinth

you had vscode open first while I asked you close it before clicking the button. it probably cant connect vsc properly rn because of your compile error

swift crag
#

Oh, that's a very important note

#

If there are compile errors in your project, new packages can't have their code compiled

long jacinth
swift crag
#

So they can't start doing things

#

If you have had errors since you started trying to get your IDE working, then you need to fix them (probably just comment everything out) so that Unity can actually compile

long jacinth
rich adder
#

fix ide first

#

then you can use a fixed ide to let it Offer suggestion to fix the error in code

long jacinth
#

it doesnt autofill still

rich adder
# long jacinth it doesnt autofill still

no. now just try redoing the steps. close vscode this time, check off the first two also cause i think its default "Embedded packages" and "Local Packages" click Regen. Double click a script from unity.

#

check the vsc console /output for any errors

swift crag
#

you must be able to enter play mode before continuing -- that proves you have no compile errors

long jacinth
#

so i check these?

#

i can enter play mode

#

is this related

long jacinth
#

yes and fully up to date

proper bobcat
#

Oh...They need the Runtime

rich adder
#

the sdk installs both, runtime an sdk

frail hawk
#

imo just use VS instead Code

#

it is way better and provides more tools

long jacinth
#

ok ig i will reinstall it

proper bobcat
#

I'd just close everything and reinstall the needed dependencies

rich adder
#

I dont need a bulky editor sometimes

Alternatively, you should change your system so that it plays the internal audio as long as any of the colliders are being overlapped

perhaps by counting up and down when you enter and leave colliders

marble grotto
# swift crag You'd get rid of the MeshCollider entirely

i believe i fixed it. I didn't fully grasp the logic of state groups. Essentially, when leaving the first mesh, i had it switch to outside ambience since it needed to do that when leaving the building. But this would mean it would also trigger briefly when moving to the corridor. So essentially what i did was remove all references to outside ambience while in those meshes and added a new box collidor by the entrance with the sole purpose of retriggering the outside ambience. A simple fix

swift crag
#

ah, is "state group" a Wwise thing?

I've been curious, does everyone write their own scripts. Or do you find something similar and modify it?

cosmic dagger

wintry quarry
#

Beginners tend to copy-and-modify because they have no idea how to start

#

but once you learn the ropes, you write your own

swift crag
#

There is one case where I do wind up modifying existing code -- when I'm doing something weird with someone else's library

#

I've made a few edits to the unity splines package to make it perform better for me, for example

#

(I need to NOT aggressively recalculate the up-vector cache on splines that are changing every single frame!)

Hi, i just started learning how to use Unity. I'm currently trying to use a tileset to make a 2d platformer but there's this bug that showed up where if I run on a flat surface, my character still gains some vertical height and goes into a jump state

#

I was wondering if its a problem with the collisions on the tiles? or the code of my player movement

#

this is my code for my player movement, as well as the colliding components i added to my tilemap

your logic is all wrong

frosty field
#

why?

languid spire
#

step through the code line by line

frosty field

oh

#

i think i get it

#

is it that if i press V, its changing to true but then instantly to false cuz when its true and get's an V input its going back to false?

languid spire
#

It's not changing to false at all.
When you press V ALL 3 of the If statrments become true

frosty field
#

huh?

languid spire
#

post your !code correctly and I'll show you

eternal falconBOT
frosty field
languid spire
#

OK. So
if (camCheck == false && Input.GetKeyDown(KeyCode.V)) is this true? Yes camCheck is false and V has been pressed
so set camCheck = true
next step
if (camCheck == true) is this true? yes, we just set it
next step
if (camCheck == true && Input.GetKeyDown(KeyCode.V)) is this true? yes
so
camCheck = false;
offset.Set(0, 5, -7);

humble forum

so although you set offset.Set(0, 2, 1); is is only for one if statement

then, when the player selects a building to construct, you would use the prefab from the list and instantiate that prefab. this will return a copy (instance) of that prefab. make sure to assign this instance to a field or list on your city (to keep track of it) . . .

i kinda hope this is a game about explaining tariffs: showing how American companies can choose to pay for them or find a cheaper competitor to buy from, the loss in revenue from said tariffs, then eventually increasing prices to recoup losses or maintain their current price, thus adding to inflation

make sure the player has the option to build factories to try to increase jobs that will lead to economic growth in their region. of course there are other factors to input, but it'd be an interesting concept for players to experience themselves . . .

no you use SetTile if you are putting a tile on tilemap

#

i dont even know what it does since that doesnt make sense coming from TileBase

#

if it needs to be a prefab use Instantiate and place it with WorldToCell / CellCenter or whatever.
if its a tile in tilemap then use tilemap.SetTile(pos, tileYouWant)

Hello everyone, i am confused about my code:

I can move fine in all directions using the keyboard.
But for some reason , when i use my dualshock 4, i can only move horizontally, but not vertically, why is that???

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

public class PlayerController : MonoBehaviour
{
    public float speed = 10.0f;
    public float jumpForce = 50;
    private Rigidbody playerRb;
    // Start is called before the first frame update
    void Start()
    {
        playerRb = GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
        float verticalInput = Input.GetAxis("Vertical");
        float horizontalInput = Input.GetAxis("Horizontal");

        playerRb.AddForce(Vector3.forward * speed * verticalInput * Time.deltaTime);
        playerRb.AddForce(Vector3.right * speed * horizontalInput * Time.deltaTime);

        

        
    }
    
    
    
}```
rich adder
#

dont use time.deltaTime on rigidbodies

#

also use FixedUpdate to move rb

wintry quarry
tawny edge
#

why? (i'm asking to undersatnd better, not to disagree with you)

rich adder
#

unless you use impulse ofc (like a 1frame jump not constant)

wintry quarry
#

Vector3.forward would move it horizontally

wintry quarry
tawny edge
wintry quarry
#

Using Time.deltaTime is not a replacement for that when it comes to physics and other simulations that have second-order functions-over-time in them like acceleration/velocity

wintry quarry
# tawny edge why?

deltaTime (or rather FixedDeltaTime) is already accounted for in the various ForceModes used in AddForce

#

what you are adding is extra noise that makes the units of the force you're adding nonsensical and unpredictable

#

By default, the force you add is measured in Newtons

#

and expected to be added consistently over time in FixedUpdate

humble forum
#

if (BuyScreen != null)
{
BuyScreen.ShowPanel();
tilemap.SetTile(clickedCell, expected);
}

but how can i make it work and have it dynamic so i can use it on all i just don t know anymore

your set tile code has to "wait" till selection is done

Hey guy, for the past week Ive been making 1 tiny project/ day to get more familiar with the Engine, it's going great but now I need to create projects with better practices such as using getter/setters, interfaces/scriptable objects, etc. i have 2 questions

  1. Where can I learn the best practices to apply in projects?
  2. Do you guys recommend a youtuber or someone who goes through best practices - sometimes im not sure what to look for, and how it would be 'best practice'

Thank you 🥳

# wintry quarry As for: > i can only move horizontally, but not vertically, why is that??? Becau...

that didn't work, i should have clarified the type of game i'm making.
Vector3.up doesn't work as it makes my character go up in the air, that is not what i wanted so i changed back.

Look at the video, on the first part when the capsule is moving only sideways, i am actually using my controller and moving the joystick in CIRCLES, he should have moved farther and closer to the screen!
At the second part when the capsule does move in all directions is when i'm using my keyboard, all directions work!

what is going on here? why does it work for my keyboard and not my controller?

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

public class PlayerController : MonoBehaviour
{
    public float speed = 10.0f;
    public float jumpForce = 50;
    private Rigidbody playerRb;
    // Start is called before the first frame update

    // Update is called once per frame

    {
        float verticalInput = Input.GetAxis("Vertical");
        float horizontalInput = Input.GetAxis("Horizontal");

        playerRb.AddForce(Vector3.forward * speed * verticalInput);
        playerRb.AddForce(Vector3.right * speed * horizontalInput);

It's possible they intend you to use a non-parametric version that is

the class itself isnt

west radish
#

It's probably a silly question, but why is it when I give my game object the foo class as the component, its the foo's Update that gets called, not the Update from the base? I'm not too sure why this doesnt give me an error too, as I didnt override anything

public class foo : MyBase
{
    void Update()
    {
        Debug.Log($"This gets printed");
    }
}

public class MyBase : MonoBehaviour
{
    void Update()
    {
        Debug.Log($"this, does not.");
    }
}```
cosmic dagger
west radish
#

ah, right

cosmic dagger
#

currently you can't because it's not virtual . . .

#

nor is it public or protected . . .

#

you need to allow the method to be overridden, and give it the appropiate access level . . .

humble forum
#

f god im done for today 🙂

north kiln
#

if these functions were public/protected you would be seeing a warning

west radish
#

What I'm not sure if is which update is the ony I should be getting Unity to call, because if I can have 2 different update methods in both the derived and base class, only one should be called

north kiln
#

Unity will call the more specific one, ie. the one in the inherited class. But it's bad to have an inheritance hierarchy and manually redefine functions like this

I don't use C++

devout flume
#

Fair enough, I'll look that up

devout flume
# north kiln I don't use C++

It doesn't hold the same meaning at all, and actually after thinking about it twice, that's quite logical because virtual in C++ has a lot to do with pointers

cosmic dagger
devout flume
#

However it will eventually prompt an issue depending on the context

swift crag
#

Both the parent and child classes declare a private method named Update

eternal needle
devout flume
swift crag
#

which is why these methods still get called even when they're nominally private

#

If it weren't for reflection, there would be no way for this ambiguity to come up at all

the differences are very minor

I got this error when trying to export from localization string table to character set for Russian, anyone encountered this?
"OverflowException: Value was either too large or too small for an unsigned byte."

image.png
swift crag
#

Oh huh, I didn’t know you could do that

#

Can you show the stack trace? Click on the message and look at the bottom of the console

rose geode
#

I'm sorry, unity localization has an error when trying to parse Russian characters, with other languages ​​like Japanese, French, Korean it's completely normal.

image.png
swift crag
#

The error is coming from code that tries to parse a format string's selectors

#

"Like this: {0}"

#

If it finds a character it doesn't like, it tries to turn it into a byte and then display it

#

But if that character's encoded value is too big, it doesn't fit into a byte, so you get an error

#

Can you check for strings that include curly braces like that?

#

If you have, say, "oops {ü}", that might break

#

(i don't actually know if that's out of range, but that's the idea)

nocturne kayak
#

Hey, i'm having a bit of trouble changing a method bool, i don't think i understand how they work properly

#

i'm calling hte onSelected() method from another script and i can trigger it no problem, however isSelected's printing false

#

what gives?

pure drift
swift crag
#

your set accessor does nothing

nocturne kayak
#

Ah, i see

swift crag
#

If you don't want to let other classes set it, use private set

nocturne kayak
#

once again the main problem in my code was between my chair and the keyboard

#

Still, i don't fully understand how the bool accessor works

#

i just saw i can't really set a variable in an interface there

swift crag
#

"in an interface"?

rose geode
nocturne kayak
#

i'm sorry, i'm still learning this as i go, but isSelected is a bool declared in an iSelectableFurniture interface which this class's pulling from

swift crag
nocturne kayak
#

apparently i can't just use the good old bool isSelected in the interface code, so i have to do bool isSelected {get; set;}

swift crag
#

Ah, yes

nocturne kayak
#

but i don't really understand why, or how to use it

swift crag
#

You cannot declare fields in an interface

# 
public class Foo {
  public bool field;
  public bool Property1 => true;
  public bool Property2
  {
    get => true;
  }

  public bool Property3
  {
    get
    {
      return field;
    }
    set
    {
      field = value;
    }
  }
}```
#

This class has one field and three different properties

#

the third property has both get and set accessors

#

I think you want to make the property only have a get accessor

# 
public interface Selectable {
  public bool IsSelected { get; }
}

public class Whatever : Selectable {
  public bool IsSelected => selected;
  private bool selected;
}
#

e.g.

rose geode
swift crag
#

Can you show an example of a string that has the curly braces in it?

rose geode
#

It is strange that complex hieroglyphs of Japanese or Chinese do not have this error.

rose geode
#

I use a lot of smart strings in localize so I'm not sure which key it's actually failing on

swift crag
#

Hmm, that seems okay. It’s only a problem if you have cyrillic characters in places like “value” or “choose” or “0|1|2” here, I’m pretty sure

rose geode
#

I see what you mean, I will check it again and hope it works.

swift crag
#

You could do that by embedding the package

rose geode
#

I found it manually, I used the auto translate function in google sheets and it produced this string
Соответствует {количество} элементов

Thanks for taking the time to help me.

swift crag
#

You'd copy /Library/PackageCache/com.unity.localization@1.5.3 into /Packages/com.unty.localization@1.5.3, then go and edit the function

#

ah, nice!

#

That sounds like a bug. I'll look at reporting that tomorrow

lets say u have 3 int field that u can modify on inspector

public int A;
public int B;
public int C;```
if i turned them into an array

```cs
public int[] Array = new int[3];```
they cant keep the value from the inspector right?
naive pawn
#

you'd have to set them again, yeah

cosmic dagger
#

nope, just set them again . . .

naive pawn
#

there's nothing to indicate that A/B/C are linked to Array

#

also pretty sure you can't restrict the array size like that, setting an array in the inspector is an assignment, it'll just get replaced with whatever size array is set in the inspector

nimble apex
nimble apex
cosmic dagger
nimble apex
#

yeah thats what i talking about

#

i can guarantee there will only be 3 fields needed

# 
    public int enFontSize = 60;
    public int tcFontSize = 60;
    public int scFontSize = 60;
    public int[] FontSizeArray = new int[3];```

if u guys curious, thats what im doing now
cosmic dagger
nimble apex
cosmic dagger
#

after you run the method and you check that each element is correctly copied, you can remove the three fields without worry . . .

naive pawn
cosmic dagger
naive pawn
#

but then why are you using an array

cosmic dagger
#

oh, for sure, haha. typically, most people wouldn't do that. though, i will say there are some scenarios where you only want a finite length for an array . . .

naive pawn
#

a limit, maybe? but an exact length doesn't seem like a situation you'd want an array

cosmic dagger
#

wait, isn't that exactly why you want an array?

naive pawn
#

if you have an exact length, that could imply each member is a specific thing. a struct would probably be better for that

#

like this situation

rocky wyvern
#

why not use a class or smt then

rocky wyvern
naive pawn
#

en/tc/sc FontSize aren't all interchangable, an array doesn't make sense for that. linear structures tend to be homogenous

naive pawn
rocky wyvern
#

probably biggest usecase for using array in a scenario like this is to iterate over elements but I would assume you don't have to do that for smt like this

#

like u just want to set xyz text font size to enfontsize if its set to english right

#

to be honest the 3 variables way sounds better

nimble apex
#

so why the hell we dont use an array to do that at first place?

# 
text.fontsize = FontArray[(int)enum]```
you can definitely do this right?
naive pawn
#

why not use a dict for that, so you can benefit from having an enum?

nimble apex
#

because u need to tune the value of the size, if u use dictionary u need to visualize it

naive pawn
#

and you can have a list/array of structs so you can use to initialize that dictionary, if you don't want to manually serialize it, so you can actually use the enum names

#

if you use a list or array to begin with, you don't see the enum order in the inspector, that's more prone to mistakes

#

also with the array, imagine you forget to set one of the values. how would you know which one you forgot to set

#

an indexed container doesn't make sense when your values are specific to each key, each enum key

nimble apex
#

YO WAIT, we actually have one script

#

u never know the whole picture of a 5+ yrs old project💩

actually no

and its lazy

btw for exceute in edit mode script, can you destroy the script itself? like remove it from the object

destroy is not working tho, because its editor mode?

rocky wyvern

yeah

destroy happens until the end of the frame

#

try DestroyImmediate

nimble apex
#

i do think execute in edit mode only scripts shouldnt follow monobehavior

#

like u just type functions and it will execute all of them at once

rocky wyvern
#

unity official docs literally say to use pascal case

naive pawn
nimble apex
#

for me , "fields" are just visible "variables", or like buttons on a control panel, they should follow what variables will be on public and private

rocky wyvern
#

Use pascal case for public fields, and use camel case for private variables: For an alternative to public fields, use properties with a public “getter” (see previous and following sections).

nimble apex
#

btw i never use m_xxxxxx to define stuffs

#

or _xxxxxx

naive pawn
rocky wyvern
#

😂 #

#

ok buddy

#

of course its consider

#

they're conventions

#

not the language literally doesn't work if you don't

nimble apex
#

having a small prefixes or symbols in front of namespace is really not used to , my own style is Pascal for all enum classes, public variables, classes and functions

camel for all private/local variables

static follows public/private

fields are visible variables, they will follow what variable should be

naive pawn
#

i don't know of any other languages that use PascalCase for fields either tbh.

rocky wyvern
#

the docs are all over the place

#

i mean ofc they are

#

its not written by one guy

charred spoke
nimble apex
naive pawn
#

nor any code, really

#

using PascalCase for fields would make it overlap with types

#

love me some Rigidbody2D Rigidbody; Rigidbody = GetComponent<Rigidbody2D>();

#

the naming is more important tho lol

rocky wyvern

ur argument makes no sense

what if you wanted to use properties

#

which is very well accepted as pascal

naive pawn
rocky wyvern
#

its the exact same as ur example

#

because u gave it a bad name

naive pawn

#

properties in unity are in camelCase too

#

unity uses properties a lot and they're all in camelCase

zzz ok i cba

nope seems like they're all properties

unless your player is a child of the camera, the camera is rotating freely of the player

whole sequoia
#

oh

#

so anything i can do to fix that

naive pawn
#

you need to apply yaw (horizontal rotation) to the player and pitch (vertical rotation) to the camera, and then have the camera inherit the yaw from the player

whole sequoia
#

i have no idea what how to do that,

charred spoke
#

Simply move your player with tge forward and right of the camera transform instead of his own. Note that if your camera tilts you will have to project the vectors on a plane defined by the up of the player

wdym what next

#

if you want it to have a double jump, implement that

burnt vapor
naive pawn
#

also why do you have 2 ifs for the same action

#

merge them into a single check

willow shoal
#

i need add else

#

and then what next?

naive pawn
#

what next for what?

#

what is your actual question here?

willow shoal
#

i just dont know what add after this if(Input.GetKey(KeyCode.R) && isGrounded) { velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);

naive pawn
#

to do what?

willow shoal
#

double jump

naive pawn
#

ok, have you researched that at all?

burnt vapor
#

If you want double jump, it's a matter of adding a boolean to check if you jumped once. Then, in your if-statement for jumping you want to check if you either jumped just once or you're grounded.

naive pawn
#

also, again, why do you have 2 ifs for the same action

#

that's going to make it impossible to do any branching conditionals

burnt vapor
#

I suggest you simply add an integer for "jump count". Then when you succesfully jump you increment it. If you then try to jump again, check if the count is equal to 1, and allow a jump again. If it's 0, check for isGrounded. Lastly, 2 always fails

#

The only thing left is setting it back to 0 when you get grounded again.

willow shoal
#

how it work

naive pawn
#

would probably be better to add a bool for that single mid-air jump

willow shoal
#

i will try

burnt vapor
#

The point is not really edge cases. That's up to them

#

Especially since there are plenty of things to consider here, and perhaps their game doesn't have ledges? 🤷‍♂️

            }

Why do i get an error here? I want to check if it is null, why don't you let me? If i understand https://stackoverflow.com/questions/9609715/creating-nullable-class is corretly. Classes are automatly nullable, rigth? TileScript? choosenTile; Something like this also didn't work

That said, your code is correct so I can only assume you have left out important bits. Please share all the code if you want to be helped.

#

The only thing I can assume is that this is a local variable, in which case you need to explicitly assign it to null

#

Right now you defined the variable, but it is not assigned

-TileScript choosenTile;

It's not complaining about checking against null. It's saying that you haven't assigned a value to the variable.

burnt vapor
#

All those yellow lines are spots where a variable can potentially be null but you have not handled it that way

queen adder
burnt vapor
#

I do have to mention that in the case of Unity a lot can be wrong so I generally add it and then use what's called a "null-forgiving operator" on the spots that are incorrect.

which line is wrong because I don't have an error and the character doesn't double jump

#

secondJump not working

naive pawn
#

you're making secondJump false when you jump the first time, instead of refreshing the jump

willow shoal
#

wait i will check

naive pawn
#

you don't need secondJump = true in the first check

willow shoal
#

oh yeah

#

thanks for help

naive pawn
#

also, use GetKeyDown instead of GetKey so it only triggers on the first frame that it's pressed instead of doing the second jump right after the first

willow shoal

ok

Heya, im testing around a bit with AI using tutorial vids and im running into an issue where my AI wont pick up the player game object, im not sure why since the player is called "Player" which is the same name that the game object finds and assigns but I keep getting null instead, any help would be greatly appreciated, my code for the AI is below.

using System.Collections;
using System.Collections.Generic;
using System.Runtime.CompilerServices;
using UnityEditor.Rendering;
using UnityEngine;
using UnityEngine.AI;

public class RKTiMove : MonoBehaviour
{
public bool isHostile;

public Transform currentWayPoint;
[Space(12)]

public NavMeshAgent AiAgent;

GameObject Player;
[Space(12)]
public float distToPlayerAttack;

public float speed = 3;

// Start is called before the first frame update
void Start()
{
    Player = GameObject.FindWithTag("Player");

    if (Player == null) {
        print("Player is null");
    }
}

// Update is called once per frame
void Update()
{
    if (!isHostile)
    {
        AiAgent.SetDestination(currentWayPoint.position);
        return;
    }else
    {
        print("Else statement worked");
        float DistToPlayer = Vector3.Distance(transform.position, Player.transform.position);
        if (DistToPlayer < distToPlayerAttack)
        {
            print("speed is 0 bozo");
            AiAgent.speed = 0;
        }
        else
        {
            print("cooking the speed rn");
            AiAgent.speed = speed;
        }

        AiAgent.SetDestination(Player.transform.position);
    }
}
private void OnDrawGizmosSelected()
{
    Gizmos.color = Color.red;
    Gizmos.DrawWireSphere(transform.position, distToPlayerAttack);
    
}

}

wintry quarry
sage steppe
#

Yeah

wintry quarry
#

If that's printing then indeed you don't have an active GameObject named Player in the scene

#

At least, not at the moment this script's Start is running

#

Make sure you actually have such an object in the scene

sage steppe
#

maybe the enemy loads before the player?

image.png
wintry quarry
#

you're using FindWithTag

#

not Find

#

So it needs to be tagged Player

sage steppe
#

ooh

wintry quarry
#

In the future for posting code: !code

eternal falconBOT
swift crag
#

The start order could definitely matter if you did something like this

sage steppe
swift crag
# 
void Start() {
  gameObject.tag = "Player";
}

and then elsewhere:

void Start() {
  var whatever = GameObject.FindWithTag("Player");
}

gotta watch out for that kind of thing 😉

#

but yes, I think you're just missing the tag here!

sage steppe
#

actually where would i drag it since i dont see any specific Player thing here

wintry quarry
#

there's nothing to drag

sage steppe
#

nvm uhh i mean like how would i tag my player to it

wintry quarry
#

You need your player object to have the "Player" tag.

#

Select the player object

#

and change its tag to Player

He was illustrating a possible source of a bug

not a suggested thing to do

its def working better

Thank you! got it working now

silk scroll

I'm using a CharacterController and ProBuilder and for some reason, OnCollisionEnter is never being called.

fluid remnant
silk scroll
#

That doesn't work either tho.

fluid remnant
silk scroll
# 
void OnControllerColliderHit(ControllerColliderHit hit)
        {
            LavaBounce bounce = hit.gameObject.GetComponent<LavaBounce>();

            if (bounce)
            {
                Rigidbody playerRb = GetComponent<Rigidbody>();
                playerRb.AddForce(Vector3.up * bounce.bounceForce, ForceMode.Impulse);
                
            }
        }```
#

i mean the code is just the void.

#

i don't know why it doesn't trigger

polar acorn
#

How do you know it's never being called

#

Have you put a log in the function? Maybe log bounce before it's checked?

silk scroll
#

I have put a log in yeah

#

I put a log to log just anything that collides and none of the Probuilder meshes are triggering it

runic lance
#

by the way, why is that people are referring to functions as "void" nowadays? 🤔

swift crag
#

it's a common error

polar acorn
#

And they don't know what "void" means

swift crag
#

void is just the return type of the function

runic lance
#

yes, but where does this comes from?

swift crag
#

it's the only keyword in the function's declaration

#

other languages might make you write, say, func Foo() or something like that

polar acorn
silk scroll
#

geez okay

swift crag
silk scroll
#

I just added Debug.Log(hit);

polar acorn
silk scroll
#

The Player has a CharacterController yeah, and the other object has a Mesh Collider

#

it's a ProBuilder object so MeshCollider comes on it by default

swift crag
silk scroll
#

Yeah, the player capsule

snow warren
#

is there any API in unity 3d texture that allows me to copy blocks of one texture image to another texture image with how i flip the image

swift crag
#

to rule out it being something with ProBuilder, add a cube to the scene and try moving into it

#

Also, it's important to note that you have to move into the collider to get a message here. If you don't add gravity, and you're just walking around on a flat surface, you will not receive messages

silk scroll
#

Alright, well I've tried jumping on it

#

I'll try the regular cube

snow warren

Hey
Guys

I am having some trouble

i wanted to import image sharp library inside unity but there is a problem

i cant use the System.Runtime.Intrinsics

i thought unity6 uses Net 8

and Memory Intrinsics was defined in .Net 5+

I dont know what to do now
any helps are appreciated

#

and all i can find by googling Intrinsics is a C++ native memory intrinsics library that .Net have bindings for

queen adder
#

If i have a class that has another class in it, something like this public class JokerShop : JokerBase
What's the term for this, is nested Class correct?(for future google searches ) And how to acces the JokerShop Class properly?``` JokerBase MyJoker = XY
Myjoker.JokerShop.DoSomethingThatsOnlyInJokerShop;
JokerShop MyJokerShop = MyJoker.Get-JokerShop(SubClass) and save as new Variable

polar acorn
#

If you want to do something that is only in JokerShop, the variable needs to be of type JokerShop

queen adder
#

Thank you !

#

so then how would I create a spring pad using Character Controller

swift crag
#

The Rigidbody wants to move the object around after each physics update (if interpolation is off), whilst the CharacterController is moving whenever you tell it to

swift crag
#

you shouldn't need to do that

silk scroll
#

No, it still does nothing

#

I guess I'd have to put an invisible cube over the ProBuilder object as a workaround.

swift crag
#

You can use that to decide how much to move in the next frame

#

You could also just store a separate "spring velocity" that rapidly decays to zero over time

#

and add that into your movement each frame

#

Lots of options there -- you're inventing your own physics :p

New to Unity, I'm trying to figure out how to "project" a png with transparency onto whatever is nearest on its path. Ideally warping to whatever is currently below it.

Literal description is it's a crosshair shaped light projecting down onto a moving tray.

I tried setting up URP to do it but some of the assets I can't replace don't have compatible shaders for URP. If it matters, this is for a VR project.

Hi, I am trying to make a simple pick up and drop system where when the player looks at an item like a flash light and presses E the item is picked up and press Q to drop the item. This is my script just a simple ray cast how can I make it so when you look at an item and press E you pick the item and press Q to drop it. I am very confused on how to do it. https://paste.ofcode.org/FvimTSGeLNVhdN3t4asNLK

#

Ah, I misunderstood -- I thought you were using URP already

red igloo
steep rose
#

you would also have to find which object the raaycast hit by either using a tag/layermask (not really recommended) or some other script which tells your grab script what it is

hi im super new to unity and i dont understand whats wrong with my code. can anyone help me?

⬆️ fix your ide so it underlines your typos

upbeat steppe
steep rose
cosmic quail
swift crag
#

Note that, if you need to install a new package to get your IDE working properly, that won't be possible while you have compile errors.

#

You may need to get rid of the script to set that up properly

upbeat steppe
#

yeah but im dumb as hell i dont what a IDE is

swift crag
#

(just move it out of your Assets folder)

steep rose
#

also you do not need if(_Inputx != 0) as InputX will be zero already if not input is added, you are also using addforce in Update instead of FixedUpdate

swift crag
#

an IDE is an integrated development environment

cosmic quail
swift crag
#

a text editor that also has features like syntax highlighting and text suggestions

steep rose
#

also unnecessary usage of getcomponent and assignment in the start function (just use the inspector)

hallow apex
upbeat steppe
#

🙏

naive pawn
steep rose
#

I mean if you don't need to get it on runtime just use the inpector to assign it

#

that would be the easiest solution

naive pawn
#

getting components on the current gameobject via getcomponent in start/awake is pretty standard

steep rose
#

well yes, but that is for when you want to get it on runtime. I don't really see any need to do that except if you just don't want to do it manually

naive pawn
#

what need is there to do it via the inspector?

steep rose
#

it is easier

naive pawn
#

but that is for when you want to get it on runtime.
no, static components are generally retrieved like this too

naive pawn
steep rose
naive pawn
#

no, dragging the wrong component wouldn't be an issue.

#

dragging the wrong object would be

#

that's not an unreasonable mistake, just dragged the wrong object, and a beginner might not think to debug that

steep rose
#

yes a wrong component from another gameobject , Also most people should know how to use their brains to figure out a problem, no?

naive pawn
#

it's an extra step that might result in bugs.
assigning it directly wouldn't. and forgetting either would result in an error either way

naive pawn
#

they don't know where to start

steep rose
#

its critical thinking, and using the tools they have to figure out solutions

naive pawn
#

or you could recommend something that isn't likely to result in bugs

steep rose
#

this is why you would teach them to use the inspector

naive pawn
naive pawn
steep rose
#

such as assigning a rigidbody and floats as they have in their script, also if you saw a field that was unassigned not only would unity tell you through errors it is as simple as dragging and dropping the correct component into it. I'm not saying the getcomponent method is bad but for this situation it would be better to use the inspector as that is what it is for.

#

this is also a good way to teach people to actually think instead of mindlessly doing things, as they will see the error and wonder how to fix it/tinker with it
