not sure if its what ur after.. but u can expand a sprite sheet and select just the sprites u need /want animated from it (Ctrl + Click) and drag into the scene.. (no need to drag the entire sprite-sheet) unless u need the entire sprite sheet

Thanks

rocky canyon

took me a minute to realize that myself..

well, depends on the context

Vector2 delta = new(-1, 1); works just fine

I am trying to make a 3D Breakout/Arkanoid game for a uni project right. The one thing I cant do is the ball movement making it bounce around the playarea using Rigidbodies. Internet is no help at all and I'm about to give up and fail this can someone help

naive pawn
#

that's not much info to go off of

#

can you describe the issue in more detail

plush kernel
#

But this is for a 3d version of breakout

rocky canyon

this is my current code for the ball it starts to work then pushes itself to the left side and stays there pushing against it

using UnityEngine;

public class Ball : MonoBehaviour
{
    Rigidbody Rigidbody;



    void Start()
    {
        Rigidbody = GetComponent<Rigidbody>();
        Rigidbody.maxAngularVelocity = 1000;
        StartCoroutine(ChangeRotation());
    }

    private IEnumerator ChangeRotation()
    {
        while (true)
        {
            Rigidbody.AddTorque(new Vector3(10 * UnityEngine.Random.Range(0, 1f), UnityEngine.Random.Range(0, 1f), UnityEngine.Random.Range(0, 1f)), ForceMode.Impulse);
            yield return new WaitForSeconds(1);
        }

    }

    void Update()
    {


    }

}
polar acorn
#

When it collides with a wall, reflect its velocity

rocky canyon
#

u could even add a bit of randomness then..

#

the torque feels unecessary.. but then again.. im not a pong expert

polar acorn
#

It'd make the ball change its heading every second

How do i run unity unit tests from the command line?

they are editor tests

idk what other tests there are but

these are editor

So I'm not if there's a better way to do this (Probably is but I'm having problems with anyways). So I am trying to put a collision on this enemy when it dashes but when it does. The collision is compressed and smaller then what it should be and I ain't sure why.

(This has both code I'm using for it.)

question: I have code that manipulates the position of my player in unity using the line transform.position += moveDir * moveSpeed * Time.deltaTime;

when that line references transform.position I am assuming its directly referencing the "Transform" tab/class on the left side of the picture that holds the x,y,z position of my character.

my question is how does transform.position reference those values? when it says transform, it doesn't seem to be referencing an object of the transform class, which is strange cus usually the notation is Object.aVariableOfThisObject. On top of that, I see a public position variable in the Transform class with some get and set code that I don't really understand, but either way, how does the line of code transform.position even reference position if the transform. part isn't even and object? what is lowercase transform even referencing?

transform is a variable of type Transform

rotund bolt
#

sorry im a beginner here, are objects named with camelCase

#

im stupid, i thought they were named with PascalCase when created

polar acorn
#

Variables would start with a lower case letter. Classes start with a capital

slender nymph
#

in typical c# standards, public properties should be PascalCase, however unity decided they would rather use camelCase for that. types should always be PascalCase

rotund bolt
#

how does the Player class access this transform object if its not instantiated in the Player class? Where's it coming from? when I look at the definition, it says its coming from the Component class, but how is Player related to Component, i don't see any inheritance there

polar acorn
#

MonoBehaviour is a Component

#

and Player is a MonoBehaviour

rotund bolt
#

oh my god

its all coming together

Does anyone know how í could make a particle System work in an UI Canvas ("Screen Space Overlay").

I have these zones and want them to glow... also an "ember" like effect from the sides...

Unbenannt.png
rich ice
#

you'd probably just render them on a different camera and then put the render texture into the canvas. i dont think you can make particle systems work directly on a canvas

dusky pike
rich ice
#

make a new camera. make sure its only rendering the PS's layer. make a new render texture. put the render texture onto the cameras output. put the render texture into a raw image on the canvas

rocky canyon
#

could just make it an image and animte it

#

if u dont u'll probably need to do extra camera work render/texture.. or use a screen-space shader

#

Render/erFeature if URP

dusky pike
rocky canyon
#

slap a particle system in front of the camera and fine-tune it til it works

So i can't figure out why is item in my game going to coords 0 0 0 and not to the point where i would like it to be, also it doesn't follow the players movement only the rotation
here's the code:
item.transform.SetParent(centre.transform, false);
item.transform.localScale = new Vector3(7f, 7f, 7f);
heldItem = item;
Debug.Log("item picked up!");
.
i also tried to add this in update but it also doesn't work:
heldItem.transform.position = centre.transform.position;
Debug.Log("pos updated");
.
pls help 🙏

#

could it that the item has no rigidbody?

slender nymph
# rotund bolt for some reason sometimes simply saving my code with CTRL+S doesnt implement the...

i mean yes, it is different than saving because it does more than just save the code, it attaches the debugger to debug play mode. but if you find that simply saving the code and tabbing into unity is not causing it to compile changes then make sure you didn't do something silly like disable the auto refresh for assets, or that some asset (like a Hot Reload asset) isn't fucking with compilation

Which object is the first transform? Which one is the second?

unique spear
#

1st is centre 2nd is the sword

polar acorn

So, from the looks of it, the sword is at the position of centre

#

there's some rounding errors because of the scale, but that object is at its parent's position

unique spear

ok

polar acorn

If that's at world 0,0,0, then so is centrum and you'll need to find out why that is there

Hi all, could I ask for help with a problem? I have a Gameobject that I want to prefab. The Gameobject has a script called AbilitySystem which as an array of Abilities . Ability is an abstract class wth concrete subclasses like RangeAttack etc. If I populate the array on my gameobject, make a prefab and then instantiate the prefab the array on the new object is empty. Do I have do serialize something more here? Thank you

short update: Prefabs worked:)

#

Im doing a car sim and the car needs a mass. Do I have to just select some arbitruary value or is there a way to use a realistic mass for the car

#

so i can take the gameobject itself and maybe utilize density of its volume to find its mass.

rich adder

when I use wheel collider is not uncommon to use about 3000 to 4000 mass on main rigidbody , which makes sense for a vehicle

Not strange. Just think about it. Imagine a ruler at 1:1:1 scale. The centimeter mark is exactly 1 centimeter away from the start of the ruler.

Now scale it up to double size. The centimeter mark is now 2 centimeters from the start of the ruler

Above here, i have a script to display a crosshair over other players. However, when the players are too far away, it doesnt work?

ive tried debug.log in the if else statements for toggling the ui but somehow both are being executed?

wintry quarry
#

well presumably there's more than one enemy

ripe matrix
#

yes

polar acorn
wintry quarry
#

Also maybe you have more than one copy of this script as well

#

So you should log more infomration

#

such as:

  • which enemy
  • which object this script is on
ripe matrix
ripe matrix
#

the rect transform of the crosshair also seems to be right

#

it is enabled as well

#

it just doesn't show when the other player is too far. However, if they move closer, it appears again

wintry quarry
#

and have you tried setting the z of the returned vector to 0?

#

WorldToScreenPoint uses the distance from the camera as the z coord it returns

#

it most likely doesn't make much sense for setting the UI, and it might be putting it out of the renderer's bounds

hey friendz, does anyone know of resources of how I'd implement "customer AI" for a coffee shop simulator game?

rich adder
vagrant pendant
#

I figured 🫠

rich adder
#

AI in generally something you do once you have some type of system in place already

vagrant pendant
#

I know it's an extraordinarily vague question but I have 0 idea where I'd begin

rich adder
#

Make the system work first without the concept of AI . Eg do transactions manually via UI buttons and such

wintry quarry
#

e.g.

  1. first they arrive at the store and queue up at the counter
  2. once it's their turn, they randomly pick a set of items to order
  3. They wait for the player to fulfill the order
  4. when the order is fullfilled they pay and leave
#

something like that

#

come up with a system

#

when you have designed a system you can think about implementation

eternal needle

worked on something like this for a sim, I can share some of the line que stuff if you'd like

behaviour trees def overkill

ripe shard
#

why?

#

its not that its a particularly complicated idea

#

or implementation even

sour fulcrum
#

i know it's kinda been mentioned before but also keep in mind that you are asking this to a room of programmers. depending on your game and what it actually needs you could end up needing something that's like 95% less complex than anything someone here is gonna offer (doesn't make those options any less valid ofc)

rich adder
# ripe shard why?

I guess with new behavior tool unity has might be easier to do actually

ripe shard
#

dude, a behaviour tree is like the simplest thing ever, it doesn't have to have a visual editor

rich adder
#

ya for some its just easier to do with an actual UI tool too

i wouldn't call a behaviour tree "the simplest thing ever" considering the average post made in this channel, no offense to anyone

I am trying to use Vector3.Dot to detect when the hand of this clock hand thingy gets to the 45 degree position. I can do it for the 12/6 oclock positions using transform.up and -transform.up, but having trouble with in between positions. How would you get a 1:30p vector, for example, originating from the center of the clock? (It's a 3D object but just rotating around one axis)

# wintry quarry What do you mean by keep it consistent

well, in the suspension im designing, I have the max height for the top of the tire (where the x is). and that is basically the chassis + a little offset. and wherever the car is , I always want that offset to be the same relative to the car. so i thought to do transform.TransformPoint(car.localposition + transform.up * maxWheelHeight) to get that position, but because of scaling it isnt actually where its supposed to be.

for some reason, the part of the code with the "roll()" function triggers multiple times after Z is pressed despite the fact that "rolling" is never set back to false (in any part of the code)

{
    if (running)
    {
        if (!rolling && activated)
        {
            rolling = true;

            crank.SetTrigger("Crank");
            roll();
        }
        else
        {
            if (Input.GetKeyUp(KeyCode.Z))
            {
                activated = true;
            }
        }
    }
}```

why is this happening?
slender nymph
#

how have you confirmed any of that

lusty flax
#

the crank thing is an animator so it tries to trigger the animation in quick succession and results in errors

image.png
#

however the animation still plays once before the error

#

so that part of the code is triggering multiple times

#

i think

rich adder
#

not even a log to check it prints twice?

slender nymph
#

you very likely have more than one copy of that component in the scene, because if that crank.SetTrigger line is the one throwing the NRE then it cannot possibly be properly setting the trigger

#

so the only explanation is another copy where crank is not assigned

lusty flax
#

yea thanks for some reason there were various copies of that script in elements that were not meant to have them (idk how they got there 🤷‍♂️ i probably hovered over them by accident or smth) and deleting them fixed the issue
thanks 👍

Having issues with applying ice physics in my platformer. It's like my player doesn't slide at all even when the function for it is called

slender nymph

you're gonna need to provide more information because you can't just drop nearly 1000 lines of no syntax highlighted, barely formatted, code and expect anyone to want to dig through it to figure out what's wrong with it

brittle isle
#

That,s the part that baffles me. In it, I call a ApplyIcePhysics function to when I'm on tilemaps tagged ice on the ground layer. The catch is that maybe my calculations for slowing down and gaining speed on ice are wrong, and so it's like my function doesn't even exist even when the log clearly says it does, feeding me the variables.

when messing around with the built in splines package myself, i notice that it becomes increasingly more resource heavy the more complex a spline is. im not sure if this is something that you can overcome by implementing your own custom system, but it's definitely something to be wary of, at the very least. this is not to mention the complexity of the math that goes into making splines in the first place

If you're using version control, which you should, you can just re-clone the repo to a new folder.

Otherwise, if you aren't, just copying the entire project folder. 🤷‍♂️

its like the old scene and scripts are still in the memory

that is better i think

then i'll go into project settings/preferences and rename it there too to finalize it

delete the old .sln files n whatnot and let the IDE make a new one w/the new project name

when u re-open a script from the new project you'll get a new one generated w/ the new name

Tuple/valueTuple vs KVP are fortunately not the same or even on par

KVP doesnt implement IComparable and IStructuralEquatable. for element wise comparison both tuple and valuetupple surely have more advantages.

Also in terms of hashcode uniqueness tupples are more superior

Keep digging, thats whats learning about. Not learn to repeat what you get told in the first place. You dont understand a word of something explained? Google it, learn how to use the docs. It all is a bigger picture of your learning curve resulting in the tools you need to solve problems instead of always looking for a premade solution. 🙂

I have a simple script that spawns enemies at a number of locations randomly which is done by having an array of empty game objects and choosing a random number from 0 - array.length then selecting the specific empty game object and getting its transform.position then spawning the enemy there. The script seems to work and spawns the enemies but for some reason I get a "IndexOutOfRangeException" everytime a spawn happens even though it works fine. I can't seem to work out what's wrong?

[SerializeField] private GameObject enemy;
[SerializeField] private GameObject[] spawnPositions;
private bool startSpawn = false;

// Start is called once before the first execution of Update after the MonoBehaviour is created
void Start()
{
    startSpawn = true;
}

// Update is called once per frame
void Update()
{
    if (startSpawn == true)
    {
        InvokeRepeating("SpawnEnemy", 1, 3);
        startSpawn = false;
    }
    
}

private void SpawnEnemy()
{
    int randomSpawnPos = Random.Range(0, spawnPositions.Length);
    Instantiate(enemy, spawnPositions[randomSpawnPos].transform.position, enemy.transform.rotation);
}
burnt vapor
#

Since arrays are zero indexed, the length must decrement by 1 to avoid overflowing the last index

#

For example, assuming your array has one entry, you effectively try to get entry index 0 or 1, meaning 1 overflows.

Its still giving me the error and now it doesnt spawn at the last location in the array

Sorry im a beginner you're gonna have to explain what you mean by "logging it"

Try changing your code to this @last owl

private void SpawnEnemy()
{
    Debug.Log($"Length: {spawnPositions.Length}");
    int randomSpawnPos = Random.Range(0, spawnPositions.Length);
    Instantiate(enemy, spawnPositions[randomSpawnPos].transform.position, enemy.transform.rotation);
}

#

My bad, I think I'm not quite understanding everything that's going on here, what is it exactly that this is trying to do?

burnt vapor
#

My guess is it either logs twice, or once and length is 0

last owl
#

yep it logs twice

astral falcon
#

well

last owl
#

first one is the correct one second is just 0 for some reason

#

Why is that happening?

burnt vapor
#

You have the script on two components

#

Change the code to this:

private void SpawnEnemy()
{
    Debug.Log($"Length: {spawnPositions.Length}", this);
    int randomSpawnPos = Random.Range(0, spawnPositions.Length);
    Instantiate(enemy, spawnPositions[randomSpawnPos].transform.position, enemy.transform.rotation);
}
#

Then you can click the log message and find where it is defined

#

Then just remove the invalid one

last owl
#

They both lead to the same object

burnt vapor
#

Then you have it defined twice

#

Scroll on the component and it's there twice

#

Alternatively you somehow manage to empty the array and then the code calls it a second time

last owl
#

Oh my god I have no idea how that happened but the script was on there twice LOL

I have this script that is responsible for loading my Loading_Scene first then inside starts loading the scene I pass in. When I start my game. It succesfully loads the First scene with loading screen scene. But through my game when I want to load another scene using Loader class. It gets inside the OnLoaderCallback but never starts the coroutine. So basically I cannot use the Loader.LoadScene twice through my game. It only works once.

BlazeBin - txywxgahxhai

A tool for sharing your source code with the world!

astral falcon
final kestrel
#

No not at all

#

I thought maybe I was giving the string wrong but It is the same as my scene

astral falcon
#

Does your log get fired in the coroutine?

final kestrel
#

Yes if it succesfully fires the coroutine I see the message. But when I try using the loader class again no. Doesnt call the coroutine

astral falcon
#

Did you check your gameobject, if its created?

final kestrel
#

Yes I did. Its there

astral falcon
#

And it never gets destroyed I guess?

final kestrel
#

I already have it on my Loading Screen scene. Before creating it in the code too

#

I thought it could be related with how I flag the booleans but I cant wrap my head around

#

Because it wouldnt get inside the OnLoaderCallback at all if that were the case

astral falcon
#

So the onloadercallback, that you assign a method to, is called?

final kestrel
#

Yes it logs the first message

image.png
#

saying it works I mean

astral falcon
#

When does that log happen. On the first load, right?

final kestrel
#

Second too

astral falcon
#

So first is not loaded default scene and second call is the loaded scene?

final kestrel
#

So my first scene is my menu scene. When I press play I call Loader.LoadScene. It works as its expected to. Then I play my game and have to use the Loader again to load another scene.

#

Then it does get inside OnLoaderCallback but never unloads the other scenes or loads the next scene. I'm still on the Loading_Screen scene.

#

When I dont start from my Menu scene and not load. Starting straight from my playable scene. Loader class works cause im using it for the first time.

I have colliders on the island "floor". Is it possible to do something like a ReverseRaycast that will get the position where there is no more land?

image.png
#

rather than making an ocean collider

astral falcon
final kestrel
#

Inside the LoadSceneAsync method. At the bottom. I'm calling Unload scene. Which checks current scene and some other scene that is not present anymore. And unloads the rest

astral falcon
#

That naming is misleading 😄 But okay, found it

final kestrel
#

Yeah sorry about that.

astral falcon
#

So your code created prefab, is not created after your first scene was loaded correctly?

hexed terrace
final kestrel
#

I already have a game object with the loader call back script attached to it in my Loading screen scene.

#

Its not a prefab

astral falcon
#

yeh, not prefab. GameObject, my bad. But you create it everytime you enter a new scene and your update is called first. And then you try to destroy it right after if its loaded (which it should I assume, as the scene got entered?)

native widget
astral falcon
#

Why not use another layered collider to check against?

#

Water != land

hexed terrace
final kestrel
#

I dont see it get destroyed

hexed terrace
#

you destroy it in code

image.png
final kestrel
#

Yes I do I was checking if it got destroyed in the hierarchy

hexed terrace
#

I dont get why you'd create and destroy this every load

final kestrel
#

Well to be fair. I followed a video for this from Code monkey.

#

This is what he does I mean

hexed terrace
#

I understand

astral falcon
#

Tbh it is kinda hard to read the code. Not to udnerstand, what its doing but just to follow. Like having your callback setting a loading state to false is wrong, as the callback should never dictate the actual state its waiting for for example. You should really, after understanding the code, clean it up a bit. As Carwash said, no need, to have one MB and GO created all the time, just make it a DDOL and listen for scene changes for example.

final kestrel
#

I see. Well I do not get why I keep creating and destroying a game object that already exists in the scene either. Also yeah I need to be specific with the names and such sorry. I thought it may be because it destroys the object without even starting the coroutine but yeah. Thanks for the help!

astral falcon
#

You also seem to be destroying your loading scene with your SceneManager loop, could that also be the case?

#

ah no, thats happening after the load. phew, yeh, its kinda ping pong in the code going on 😄

final kestrel
#

Yeah I'm also having hard time navigating. I'm really sorry about that 🙂

#

What is weird is that why does it work the first time.

astral falcon
#

Nah, its fine. Its all part of the learning curve 🙂

#

I guess, your assumption about some boolean or whatever not being correctly reset or soemthing might be the issue. But I 100% bet, rewriting to your own needs and with your own understandable structure and naming is less time consuming then trying to understand the structure the tutorial provided 😄

final kestrel
#

Yeah that I agree. I could just load my loading screen scene then load the next scene non additively but I just wanted to make this work cos I had a Init scene previously I wanted to keep.

astral falcon
#

You can of course take parts out of it. But as you said, you know, what you actually need.

final kestrel
#

I simply refused to accept the defeat but yeah. Thanks for your time I'll find a workaround!

astral falcon
#

haha, yeh I know that feeling. But you yourself already found out, that the code was not optimal, so you are able to write a better one 🙂

final kestrel
#

Well I hope so. Haha we'll see!

What is a good way to truncate positions of a vector? Math.Truncate() seems to be doing funky things for me, with the top value being the Math.Truncate()'d version and the bottom being the world position of the vector

image.png
#

I guess I could also cast it to an integer and then back to a float..?

timber tide
#

There's Vector3Int if you want to just use ints

wintry quarry
#

Just for logging or display? Or what?

#

Also showing the actual code you did would help us explain why you're seeing weirdness

cosmic dagger
#

Use Vector3Int instead. If you cast to an int, the values under 0 will be 0 . . .

little seal
# 
    Vector3 GetClickedPos(out RaycastHit hit)
    {
        Vector3 target = Vector3.zero;
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        if (Physics.Raycast(ray.origin, ray.direction * 10, out hit))
        {
            if (!IsPointerOverUIObject()) target = hit.point;
        }
        return target;
    }

why does this return a height of 0? shouldnt it be .5 the object im hitting has a transform at 0 and the box collider and scale is 1 thick
it does return the right x and z

image.png
bitter apex
#

i need to round to the nearest integer to 0, so like 21.65 to 21. -17.93 to -17. my actual vector can't be an integer though as I'm adding 0.5 to each component of the vector

bitter apex
#

i need negative values too

wintry quarry
#

What are you doing with them

bitter apex
#

I'm just trying to get a vector, that's literally all I'm doing

wintry quarry
#

To do what with

#

Sounds so far like you could be using Vector3Int

#

But truncate would work if used correctly

#

Or Round

#

Or Ceil

#

Or Floor

#

Depending on the requirements

cosmic dagger
#

Use Mathf.Floor then . . .

#

Or FloorToInt if you want the result to be an int . . .

polar acorn
#

Cast it to Vector3Int when you need the ints, but keep it as a float for your computational purposes

bitter apex
#

Okay, thank you.

bitter apex
little seal
polar acorn
little seal
polar acorn
#

Did you log that inside or outside of the IsPointerOverUIObject check? If that's true, it won't change target from its default value of 0

But as Praetor suggested, telling us why you need to do this can help you find the appropriate solution . . .

You're nesting methods which you probably don't want to be doing here

scarlet grove
timber tide
#

It means don't create methods/functions inside of other methods

scarlet grove
scarlet skiff
# timber tide more information

playerCapsule has a rb
so does the stick.
nothing changes the position of the stick in the code except for this upon collision:
itemComponent.transform.localPosition = Vector2.zero;

when on ground its gravity is 1, upon collision it gets set to 0.

and this is the method that moves the player:

void  OnMove(InputValue value) 
{
    Vector2 input = value.Get<Vector2>();
    // If any horizontal key is pressed, use its sign (1 or -1), otherwise 0.
    float horizontalInput = input.x != 0 ? Mathf.Sign(input.x) : 0;
    moveInput = new Vector2(horizontalInput, 0f);
}
timber tide
# scarlet grove how would i go about fixing that ?

You should find yourself some tutorials to follow. Sorry, I'm not that great at throwing resources at this stuff, but you're obviously somewhat new at c# and you're just going to run into more issues until you learn it properly, and jumping right into Unity without knowing what's wrong here just going to make your life even more difficult on your path on learning.

Disabling is fine, yes. If say you wanted to use the stick as a weapon with physics and a child to the player -> requires some custom logic

scarlet skiff
#

oh wait u cant enable and disable rbs

#

i guess kinematic it is then?

timber tide
#

Yeah, if it's like an inventory thing where you're storing these objects you can probably just switch kinematic on and off

scarlet skiff
scarlet skiff
timber tide
#

If you wanted to use the stick as a weapon, stick to kinematic

#

but if you were to drop it on the floor and want that physics, then you can toggle it like that

scarlet skiff
timber tide
#

Usually you use the animator too when it comes to weapon attacks anyway, but I guess you probably manage something through code

#

there's actually some benefit of using kinematic vs just animation, but that's a pain to really do

timber tide
#

but remember that collision isn't handled when it's kinematic, but you will still get callbacks from the OnTrigger methods

grand snow
scarlet skiff
timber tide
#

Kinematic doesn't handle any sort of collision. If you added velocity like gravity to it, it'll clip through the ground unless you tell it not to

It will however notify you that "hey, I touched ground just so you know"

# scarlet skiff or so i think, its my first inventory that i make

another idea too is just destroy the actual item when you pick it up and store it as data if we're talking about a UI representing the items. And, when you drag the UI element out of the inventory to drop it you would instantiate this rigidbody scene element again. But, if you're not making an infinite inventory, it's fine to just stash the monobehaviours

grand snow
rotund bolt
#

most definitely

scarlet skiff
# timber tide another idea too is just destroy the actual item when you pick it up and store i...

yes but there is also the pickedup state is a li lcomplex because i want the itemto be usable as well, that u can see the player holding it etc, so what i did is that once picked up, i disabled all its hitboxes, and as u now know change rb to kinematic, and parented it to the player, i do that will all items, just that the only visible one is the selected item. i assume there are more effecient ways but oh well, i also only have a hotbar in the game no full on inventory, so this works fine i think

You can also adjust the damp time to change how smooth your transition is. This function will also automatically account for player movement mid-lerp.

}

void Change(int num) {
  num = 10;
}```
it will print 5.
But if you do:
```cs
void Test() {
  int x = 5;
  Change(ref x);

  print(x); // this will print 10
}

void Change(ref int num) {
  num = 10;
}```

It will print 10, because since it's a reference we can change the variable from the caller.

Hello, can someone help me with something about camera rotation and change directions? Like, when I rotate my camera, the player direction chage, like if I'm stiff facing noth and walking to the north and I rotate my camera, my player still walking forward (I don't know if it is understanding)

surreal minnow
#

Is there no events for animation ends/stop or do I need to make the logic myself?

shut warren
wintry quarry
#

it's whatever code you're using to rotate your player

#

Also potentially because you haven't enabled interpolation on your player Rigidbody

#

(if you haven't)

#

Oh yeah sorry it's this:

        playerBody.Rotate(Vector3.up * mouseX);```
#

You can't rotate a Rigidbody via the Transform

#

unless you want it to be jitter city

#

instead do:

myRigidbody.rotation *= Quaternion.Euler(0, mouseX, 0);```

you are a godsend, i hope you win the god damn lottery, thank you 🙏

#

i watched a video about yandere devs code and it said i should not initialize a module more than once if not necessary right? what do i do instead of that

wintry quarry
#

What do we mean by initializing modules in this context?

#

What "module" are you initializing right now and when and where are you doing it?

slow knot
#

i realize now that it probably isnt the issue but just in general, oh yeah its GetComponent<componentname>(); not initialize component

#

too much python in my brain

surreal minnow
#

Can anyone explain what component makes this pill hitbox? I need to disable collision temporarily

image.png
rich adder
wintry quarry
surreal minnow
#

Is there a property to disable its collisions?

wintry quarry
#

Disable it

#

what do you mean exsactly though

#

like other things colliding with it

#

or it colliding with things when it tries to move?

surreal minnow
#

Yeah when i climb the ledge of a cliff the hitbox is pushing against the terrain

rich adder
#

you can like Nudge it up or down depending where you want it to go

wintry quarry
surreal minnow
#

Yes I will show a video clip one moment

#

Seems to be pushing against the terrain, not sure how else to do this other than to disable collision temporarily

wintry quarry
#

but no the CC will not "push against" terrain really unless it's moving via Move()

surreal minnow
#

Well I tried but it doesn't disable it. I put

GetComponent<CharacterController>().detectCollisions = false;

Inside Start() and the character should fall through the map, no?

rich adder
#

why not just GetComponent<CharacterController>().isEnabled = false

#

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/CharacterController-detectCollisions.html

This method does not affect collisions detected during the character controller's movement but rather decides whether an incoming collider will be blocked by the controller's collider. For example, a box collider in the Scene will block the movement of the controller, but the box may still fall through the controller if detectCollisions is false. This property is useful to disable the character controller temporarily. For example, you might want to mount a character into a car and disable collision detection until it exits the car again.

wintry quarry
rich adder
#

im confused why its not working then so Id say just disable it lol

wintry quarry
#

GetComponent<CharacterController>().enabled = false; is how you disable it @surreal minnow

surreal minnow
#

Well the issue with that is:

image.png
wintry quarry
#

correct

#

don't call Move on a disabled CC

rich adder
surreal minnow
#

But that would disable air strafing, wouldn't it?

rich adder
#

yea

#

so maybe disabling the entire thing might not be what you want

wintry quarry
#

are you supposed to be able to air strafe while doing the climb animation?

surreal minnow
#

No but Id imagine in the future I would want to be able to move left or right while grabbing the ledge

rich adder
#

you could always use raycasts so when you move left and right you dont phase through walls while collider is disabled

#

like everything in development comes with its own compromises for each solution, either have a solid controller and manually deal with offsetting it.. Or disable it but that causes youto not bump into colliders at all which will make you phase through them unless you use a prevention like stopping movement with ray detection

polar acorn
#

Seems like you might simply not want to use the CharacterController

#

It really is only meant for incredibly simple movement and it sounds like you want something more granular

surreal minnow
#

You are probably right about that^

rich adder
#

CC is still very much easy to use for collision detection and steps / slopes

#

something you'd have to manually code when on ground

#

even RB makes this annoying as hell in comparison

fallen jacinth
#

Hello everyone everytime i install unity it's stuck at this

pCntIJf.png
rich adder
#

also wait a while

fallen jacinth
#

oh

surreal minnow
#

Well I have to switch from it if I am not able to do something as trivial as disabling its collisions

rich adder
surreal minnow
#

But it disables the whole component, not just collisions

#

I guess I can try making the collision box size 0 and see if it works

rich adder
#

the whole component is moving collider

#

collision is what its meant for

rich adder
#

CC just makes so when you do move an object its with Physics aka collisions

#

As I mentioned when you switch to disabled you can freely move the object without CC

#

you just need to account for collisions yourself on edge for example

#

hence the suggested Raycasting for such detections.
if(leftSideRaycast) // if hit a wall
{dont move this way} etc.

surreal minnow
#

Yeah I know. You are right and that it is a possible way. I am just debating if there are any future cases where it could screw me over

small dagger
#

Is setting a collider to be a trigger the only way to detect if it collides with something without interacting with physics?

polar acorn
#

That's basically the definition of a trigger

small dagger
#

yeah it's not really a big problem for me, I just have a swtich-case statement in my "oncollisionenter" method and I just wanted to see if I could sneak the pickup in there

#

but I guess I will just have to settle for putting it in ontriggerenter

frigid sequoia
#

Is there a way to tell if a component is missing?

naive pawn
#

from what context?

frigid sequoia
#

Like players have X script as target, but it was destroyed and it's now missing, that's not really null, how can I tell that it's misssing?

naive pawn
#

it'll say it's missing in the inspector

frigid sequoia
#

Yeah, I want to tell the scrip that if that happens, set it to null instead

swift elbow
#

what's stopping you from just checking if the class reference exists or not?

frigid sequoia
#

Exists?

swift elbow
#

use an == null check

grand badger
#

they're looking for an editor script, guys

swift elbow
#

yeah would == null not override?

grand badger
#

Daleo you need an editor script for sure. I'm not sure the exact code atm (no time, sry)

frigid sequoia
#

Pretty sure "missing" is not = "null"

rich adder
#

most likely youre starting the coroutine more than once

red igloo
rich adder
# red igloo I will look into this thanks

You can use a bool to avoid start a new one unless bool is true, or store the Coroutine in vairable and set to Null when coroutine is done.
Most often I use variable
private Coroutine myRoutine
myRoutine = StartCoroutine(TheRoutine())
if(myRoutine != null) //stuff

#

StopCoroutine(myRoutine) or avoid StartCoroutine while its finishing

While the game is running

fleet venture
#

well ye

polar acorn
#

How do you intend to make a playable game if you have to drag in references while it's running 🤔

fleet venture
#

no

#

you dont drag them while playing

#

sorry misunderstanding

#

the dragging isnt at runtime

#

the usage of the prefabs IS at runtime

polar acorn
#

So then it doesn't need to be included in the build

#

It's an editor script

fleet venture
#

what no its not

#

ok

#

you dont have to drag references while its running

#

but i need to get a prefab based on a name

polar acorn
#

Right, so you don't need to include it

fleet venture
#

for loading/saving purposes

polar acorn
#

Put it in an Editor folder or exclude it from your assembly definitions if you have them

red igloo
grand badger
fleet venture
#

im trying to use Resources.Load now

polar acorn
fleet venture
#

its a runtime script

#

i think you misunderstood what i meant

#

i have a save, that stores a prefab id, i want to create a new instance of a prefab based on the id

#

so the id is the name of the prefab

#

rn i use the AssetDatabase to get the prefab dynamically to instantiate it

polar acorn
#

If it can be circumvented by dragging in a bunch of prefabs outside of runtime, it almost certainly can be an editor script

fleet venture
#

i dont get what an editor script would do

polar acorn
#

Assign the prefabs for you

#

So you don't have to drag them in

fleet venture
#

i have no idea how i would make that

#

cant i just do this dynamically?

#

why does it have to be hardcoded 💀

polar acorn
fleet venture
#

var guid = AssetDatabase.FindAssets(prop.prefabId.Replace("(Clone)", ""), new[] {"Assets/Prefabs"}).FirstOrDefault();

#

and then i

#

var propObject = Instantiate(AssetDatabase.LoadAssetAtPath<GameObject>(AssetDatabase.GUIDToAssetPath(guid)), new Vector3(prop.posX, prop.posY, 100), quaternion.Euler(0, 0, prop.rotation));

polar acorn
#

So, you know how to load a prefab by name.

You can set variables of scene objects outside of play mode using an editor script

fleet venture
#

im not entirely sure what you mean sorry

#

what i would do is like, create a dictionary with strings as keys and gameobjects as values

#

but idk how i would fill it

hollow wraith
# polar acorn a `Color`

Am I doing something wrong?
I've made sure everything that could be wrong is right but I still can't get the sprite to change colour

image.png image.png
polar acorn
fleet venture
#

dictionaries dont even work well with unity

polar acorn
fleet venture
hollow wraith
polar acorn
#

so it automates dragging in

fleet venture
#

you can do that?

polar acorn
#

Yes, like I said, an editor script can set variables on objects in the scene

fleet venture
#

okay i understand

#

ye that would be better than dragging

fleet venture
#

cuz normally a dictoinary doesnt work with dragging

polar acorn
#

You could make a serializable extension of a Dictionary that'd get saved, but the built-in C# dictionary is not

fleet venture
#

ok im not doing that

#

i still hate that its not serializable

#

a dictionary is so basic

fleet venture
#

i cant rly find it when searching for editor scripting

rich adder
#

since you can use anything as a key

polar acorn
fleet venture
#

editorscript

#

like for how to assing the variables

#

and for where to put the script and stuff

polar acorn
#

Then you'd execute the function by selecting it from the top bar

rich adder
fleet venture
#

it says not to use that

#

lol

polar acorn
rich adder
#

its fine for now(IMGUI) but yeah just kinda dropped that without contex mb

polar acorn
fleet venture
#

ah

rich adder
#

but yeah for future reference, Unity DOES want you to merge everything into UIToolkit eventually but thats another topic 😅

#

nothing wrong with IMGUI if you ever need some quick editor magic

fleet venture
#

the menu itme thing is to create new stuff?

rich adder
#

yea you can run function easily from right click

#

or the toolbar in this case

fleet venture
#

i want to add stuff tho

rich adder
#

what is "stuff"

fleet venture
#

oh wait i use FindObjectsOfType

rich adder
#

what do you want to add

fleet venture
#

the prefabs to the variables and strings

#

i use FindObjectsOfType for that?

rich adder
#

sure if you want to

#

its grabs them into an array

#

in editor those functions have no impact on gameplay anyway
(in game ofc u dont want to run that in update)

fleet venture
#

where is taht in

#

oh this should still be a monobehaviour?

#

uh it does say deprecated

rich adder
#

FindObjectsOfType is a static function

fleet venture
#

ah by type ofc

rich adder
#

unity switched up some functions in unity 6

fleet venture
#

i want the sorting order to be from top to bottom tho but thats not an option

image.png
#

im not sure how they are sorted in the editor

rich adder
#

alphabetically

fleet venture
#

oh

#

okay so next question, how do i then get the object in the scene?

rich adder
#

do you have some sort of identifier ?

#

to grab it

fleet venture
#

well its the only one of that type

#

so if i can do something similar to FindObjectsByType but for in teh scene

rich adder
#

oh its part of the scene already or you want to spawn it ?

#

Im confused on what you're going for I kinda just butted in at the end 😅

fleet venture
#

i want to link a prefab in assets, to a script variable in the scene

#

or well i want to link 200+ prefabs

rich adder
#

and you cannot use SerializeField why ?

fleet venture
#

i dont want to drag 200+ prefabs

#

i was told i can get unity to put them in for me with an editor script

#

so i dont have to drag

rich adder
#

ohh so you wanted a function to run in editor to do that/

fleet venture
#

yes

#

but ive never wrote an editor script so i dont really know what i am doing

rich adder
#

editor part is not important, its more important is how you want to grab/distinguish between these

#

eg if all Furniture had a Furniture component its a lot easier

fleet venture
#

i want to get all of these

image.png
#

all the prefabs have a Prop script

rich adder
#

I get that

fleet venture
#

ONLY the prefabs have that script

rich adder
#

but whats on the prefabs

fleet venture
#

Prop script

rich adder
#

so then FindObjectsOfType<Prop>()

fleet venture
#

ye i have that part down

#

but how do i get the object in the scene and how do i put it in the variable of said object

rich adder
#

place them in categories so they are easy to grab

#

say you want to place all barrels you could store them in List<Prop>barrells

#

perhaps here it would be okay to check their name

fleet venture
#

yes thats what i want to do but how do i store them

#

i have a List<gameobject> and a List<string>

#

the strings will be names

#

its basically key value

rich adder
#

why two lists

fleet venture
#

because a dictionary is not supported

#

sadly

rich adder
#

it is

#

just not serialized in editor

fleet venture
#

i dont want to make my own

#

oh wait so i CAN do a dictionary?

rich adder
#

ofc

fleet venture
#

i would much rather do that

#

its way cleaner

rich adder
#

you just cant see it in the inspector

naive pawn
#

there is a premade serializeddictionary package
