alternatively, if you just want to check if something is in that space and don't need access to the colliders just use a CheckBox instead of OverlapBox

lusty socket
#

Does any object in the array have any part of its bounding box intersect with the bounding box of the given box?

#

i think thats right

polar acorn
wintry quarry
#

you're asking if there are any intersecting colliders.
The function you're using returns an array of intersecting colliders.

A Collider[] is not a true/false (aka bool)

lusty socket
# polar acorn

so its just asking is any other colliders overlapping?

#

with the box

wintry quarry
#

no it's asking which colliders are overlapping

#

and gives you an array containing all such colliders

lusty socket
#

so what do i need to add to this line of code in that respect then?

wintry quarry
#

think about it

polar acorn
wintry quarry
#

how do you go from an array of colliders to an answer to your question "are there any colliders"?

#

what would that array look like if there are no such colliders?

#

what would it look like if there is at least one collider?

short hazel
#

Alternative:
Use Physics.CheckBox() if you don't care about which colliders it detected, just if it detected anything. Returns a bool, so should be compatible with your method.

lusty socket
#

I understand the second question being no and the third question being yes, but the first question is just kinda going over my head

wintry quarry
lusty socket
wintry quarry
#

I'm asking how you would write code to determine that

#

and yes SPR2 is correct and you should be using that instead, but if that didn't exist, you should be able to figure out how to use OverlapBox

lusty socket
summer stump
#

How would compare the integer value to turn it into a bool?

#

Arrays have a length property to see how many elements are in it btw, if that is the part you are struggling with

green copper
#

do I need to do something special to make it "remember" the variable from the previous loop?

wintry quarry
#

you'll need to account for the case when selectedObject was not assigned yet, yes

green copper
#

Ohhh DUH

#

oops

wintry quarry
#

the variable already remembers from the previous execution, that's the point of the variable

green copper
#

sorry

lusty socket
#

return Physics2D.OverlapBox(coll.bounds.center, coll.bounds.size, 0f, jumpableground); so is that right? as there is 0

wintry quarry
#

you can't interchange them

lusty socket
#

sorry i didnt mean to add the 2d id just hit the wrong one, i meant Physics

#

return Physics.OverlapBox(coll.bounds.center, coll.bounds.size, 0f, jumpableground);

#

that is what i meant

summer stump
wintry quarry
summer stump
wintry quarry
#

think about what OverlapBox returns

wintry quarry
summer stump
#

Damn, too slow

wintry quarry
#

I'm not even really sure which Vector2 you're talking about, but it doesn't matter much

wintry quarry
lusty socket
#

i thought thats the issue because when changing boxcast to overlap box the error was cant convert vector2 to int

wintry quarry
#

This was the error

#

Cannot convert Collider[] to bool

#

Does Unity require .NET framework?

summer stump
summer stump
lusty socket
summer stump
#

How would you turn that into a bool

#

What comparison would you make?

lusty socket
#

is there any colliders in the box

summer stump
#

Yeah... and what comparison operator would you use?

lusty socket
#

= 0

wintry quarry
#

and what things would you actually be comparing?

#

what do you want to compare to 0?

summer stump
lusty socket
#

the integer value and the bool is what we are comparing

wintry quarry
wintry quarry
lusty socket
#

how many colliders are in the box

wintry quarry
#

there's an array of colliders

wintry quarry
#

we have an array of colliders

lusty socket
#

i think thats throwing me

wintry quarry
#

but it's also completely irrelevant

#

ignore what's inside there

# 
bool MyFunction() {
  Collider[] colliders = Physics.OverlapBox(/*stuff that doesn't matter*/);
  return ??? // << what goes here?
}```
lusty socket
#

i see

wintry quarry
#

what do we put in place of the ???

#

we have an array of colliders called colliders, which contains all of the colliders that are in the box

#

we want to know if there was something or nothing in the box

#

what do we do?

lusty socket
#

collider length

wintry quarry
#

Good!

lusty socket
#

needs to me more then 0?

wintry quarry
#

yes!

lusty socket
#

return colliders.Length > 0;

#

so itd look like that

wintry quarry
#

yes!

#

that will return true if there are colliders in the box

#

false if there are no colliders in the box

lusty socket
#

private bool IsGrounded()
{
Collider[] colliders = Physics.OverlapBox(coll.bounds.center, coll.bounds.size, 0f, jumpableground);
return colliders.Length > 0; // << what goes here?
}

#

so this should be correct?

summer stump
#

Should be, try it

lusty socket
#

Argument 3: cannot convert from 'float' to 'UnityEngine.Quaternion'

#

i get that errpr from the 0f

polar acorn
lusty socket
#

do i need to change that to Quaternion.identity

polar acorn
#

I sent you the documentation for OverlapBox that shows what parameters it expects and in what order

lusty socket
#

or am i on a completely different track

Why does my pc crashes when I save a script in Visual Studio? My whole pc like hangs and crashes.

is it possible to reference "other" from outside of an OnTriggerEnter method?

summer stump
#

Otherwise no, it is locally scoped

muted wadi
#

how would I save it to a variable?

summer stump
#

Make a variable of that type, and use an equals sign

muted wadi
#

just set one beforehand and inside the method assign other to that variable?

summer stump
muted wadi
#

oh ok

#

so I am doing it right

#

in that case how can I make a variable inside ontriggerenter update even if the method isn't called?

You would also have to check if it's null before using it because of what you said

im trying to track the distance from the center of trigger object and the center of the object that has triggered it

wintry quarry

but anyway you'd just make distFromCenter a property - so it gets calculated whenever you use it:

float distFromCenter {
  get {
    return Vector3.Distance(mostRecentNote.transform.position, hitCollider.transform.position);
  }
}``` and save the note in a variable called mostRecentNote

i have a question

#

how do i make my character to hide then wait 1sec and then show again and play an animation

wintry quarry
#

or bake all of that into an animation

flat slate
#

but the problem is that i cant use a coroutine when the character hides

#

or can i?

wintry quarry
#

you can use a coroutine whenever you want

#

I guess you're saying if the coroutine is on the character and you are deactivating the character object? No, but you get around that in many ways:

  • only disabling the renderer, not deactivating the whole object
  • putting the renderer on a chilkd object and deactivating that
  • running the coroutine on a separate object entirely

I'm wondering if using the exact size of the collider is making it so it doesn't reach the ground

does anyone understand how to make navmesh stuff work? every video tells me to download specific components but I assume these old videos only have links for stuff that won't work with my unity version

summer stump
#

Capital L, sorry

lusty socket
#

or update i meant

summer stump
#

Do it in IsGrounded

#

You can't access colliders outside of IsGrounded

#

It's a locally scoped variable

lusty socket
#

okay i meant update anyways i thought that would tell you for every frame

lusty socket
summer stump
#

Since you call that method in update

summer stump
# lusty socket ohhh i didnt know that thasnkyou

Anytime you declare a variable, it will have a scope. If you do it in a method, its scope is that method. If you declare it in a class, its scope is that class (but in that case you can use access modifiers to change the scope it can be accessed in)

lusty socket
#

should i worry about the error?

ss19.png
summer stump
#

It is saying the debug can litterally never be accessed or run

#

You return from the method the line before it

#

So it will NEVER run

lusty socket
#

how do i fix that?

summer stump
lusty socket
#

so i need to remove the return before colliders length/

eager elm
#

a return ends the function

summer stump
#

No no no

#

Just simply move the debug lol

lusty socket
#

i got you

#

so just inbetween the lines of code is fine?

eager elm
#

Select with your mouse the Debug.Log() line and press ALT + UpArrow

summer stump

summer stump
#

Move it down

weary crystal
#

Umm how do I duplicate tilemap objects...?

lusty socket
# summer stump Move it down

ive moved it so it is as on the ground as it can be and even in the ground so when hitting play it bring it up to the ground but no change

summer stump
#

Hopefully not the player?

lusty socket
summer stump
#

Offset the position downwards

#

You use coll.bounds.center

#

And the size

#

But the colliders prevent it from going into the ground..

#

Also, can you show a screenshot of the inspector of the ground

wintry quarry
lusty socket
#

so i just add down to the end of the coll.bounds.centre and coll.bounds.size or am i wrong

#

ignore me

#

theres inspector of the ground + the new code to size down and move down, but still no change @summer stump

ss20.png ss21.png
summer stump
#

Also... just to make sure... show the layermask field

lusty socket
summer stump
#

Also, why have a GroundLayer and jumpableGround?

lusty socket
summer stump
#

Is _Idle_0 your player?

#

And I wanted the layermask expanded, but it shows Ground so that should be fine

lusty socket
#

i had an old way to do the ground check involving a ground layer so when it is detecting the ground then i can jump, if no ground is detected then the player jumping is true but i replaced it with the new one and forgot to delete the old layermask

weary crystal
#

Is this the right way to do what I'm trying to do?

{

I hope you understand the code, I don't know how to explain rn :/
lusty socket

#

yes size is as it was before moving it down and making it smaller

summer stump
#

Like, the debug still shows 0?

lusty socket
#

yeah still just stuck in jump animation and debug saying 0

#

if it helps its also showing the debug a second time every time i press the space bar, aswell as ever frame

summer stump
#

But I dunno if that is strictly necessary

#

Can't check, as I'm on my phone

What I am trying to achieve is this:
I have a linePrefab to which LineController script is attached. Similarly I have a TravellingBallPrefab to which the TravellingBalls script is attached. The balls are spawned after every "interval" & travel along the line with "speed", & have "lifeSpan". These speed, interval, lifeSpan are controlled via SlidersWithEcho script which has the sliders.

The issue I am facing is this:
Except for speed, the interval & lifeSpan for the balls prefab is not being controlled properly. I wanted every ball to have it's own speed, lifeSpan & interval I think can be common because after every interval new ball is spawned. How can I properly use sliders to manipulate the lifeSpan & interval after which ball will be spawned?

Ok I need serious help right now, I'm trying to make a game in which you're a square trying to avoid touching the top, bottom and the objects that'll appear in your path, the thing is I'm adding the force to move up(The only thing you can do is move up, the square will go down because of the rigidbody) adding the force make square go up too fast or too slow and I'm confused what to do here :/ It's 2D game btw

Here's the code if needed:

using UnityEngine;
using UnityEngine.SceneManagement;

public class playerMovement : MonoBehaviour
{
    public float movementSpeed;
    public float jumpForce = 10f;
    private Rigidbody2D rb;
    public string sceneName;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        if (Input.GetMouseButton(0) || Input.touchCount > 0)
        {
            rb.AddForce(Vector2.up * jumpForce, ForceMode2D.Impulse);
        }


        transform.Translate(Vector2.right * movementSpeed * Time.deltaTime);
    }

    void OnCollisionEnter2D(Collision2D collision)
    {
        SceneManager.LoadScene(sceneName);
    }
}

Sorry for writing a long ass message btw

polar acorn

That's going to wreak havoc on your momentum.

#

If you're using physics, don't move with translate

lusty socket
weary crystal
#

That makes my game 10 times more harder

polar acorn
#

If you want the speed to instantly change to a fixed amount, modify velocity instead of using AddForce

wintry quarry
#

if you used FixedUpdate and/or GetButtonDown it would work more consistently

#

never add force in Update

Why is this function not resulting in the camera not returning to the position it started, I understand why it might be off by a little but it's like not even moving back at all: https://hastebin.com/share/ebekajiser.csharp

Do you get both logs?

crisp token
#

yeah

#

they're different values tho which is weird

#

oh actually it makes sense y theyre differnt

polar acorn
#

Log the position before the first loop, between loops, and at the end. Give them each a different prefix so you know which is which. Debug.Log($"Before: {transform.position}"); and then the same for middle and end

crisp token
#

Here its only off my one tick which makes sense, but sometimes its a lot worse, let me see if I can get an example

#

I have a feeling the issue is coming from a different script

polar acorn
#

You're going to be off by one or two on occasion. You said it wasn't moving back at all which is a different problem

if I want to implement IEnumerable<T>, why do I need to implement both IEnumerator IEnumerable.GetEnumerator() and public IEnumerator<TStored> GetEnumerator()? Isn't it a bit redundant?

muted wadi
#

is there a function in unity like CrossFadeAlpha but for the size of a text element instead of alpha?

sweet zenith
#

DOTween is pretty popular

muted wadi
#

What is a tweening library?

sweet zenith
#

It's a library for changing one value to another over time

muted wadi
#

Ah

sweet zenith
#

Like moving an element around, or resizing, shaking etc

#

But if you want to do it manually you can too

muted wadi
#

That sounds like exactly what I need

sweet zenith
#

I would recommend trying out DOTween

#

Actually there's another one on the asset store that's meant to be way better...

muted wadi
#

Is it not a standard unity asset that comes with every project?

sweet zenith
#

PrimeTween

#

No, they're third party

muted wadi
#

Because this sounds really good, I'm just not sure if I'm gonna be able to use them since they're a third party addon

sweet zenith
#

Or because it's a school project/

#

Most ppl add a tweening lib to their unity projects

#

But if you can't, you can write your own

muted wadi
sweet zenith
# 
static IEnumerator TweenLocalScale(Transform transform, Vector3 to, float duration) {
  var from = transform.localScale;
  var startTime = Time.time;
  var endTime = startTime + duration;
  while (Time.time < endTime) {
    var t = Mathf.InverseLerp(startTime, endTime, Time.time);
    transform.localScale = Vector3.Lerp(from, to, t);
    yield return null;
  }
  transform.localScale = to;
}

//

StartCoroutine(TweenLocalScale(someTransform, Vector3(1, 2, 3), 1f));
muted wadi
#

Now that I think about it I should be fine considering it's just a library, unity has plenty that we already use

sweet zenith
#

So long as the library isn't doing the core thing you're being assessed on

#

Just ask your teacher

#

I would definitely recommend using a library over writing it yourself

#

It's a good tool to know

muted wadi
#

Oh nah I just want to cut down the time spent programming tiny cosmetic changes, the core stuff is all me

Hey guys I was following someone's tutorial where they gave a ragdoll a 3rd person camera controller: https://hatebin.com/fwidzztlpp but after following their steps and applying the component, the camera moves left and right when you move your mouse up and down, similar to in real life when you tilt your head from left to right, side by side. Could anyone help me with this?

how could i make a slot be able to hold up to 160 of the item thats inside it?

#

i already have item data for each item to have a stackable bool

#

but im not sure how id make stacking in the actual slot

teal viper
acoustic arch
teal viper
#

Then I don't get the question

acoustic arch
#

nvm i was confused

acoustic arch
#

if its a stackable item it should instead go to the ItemStack class instead of the slot class?

#

or both and the slot just holds data but not like the amount

teal viper
#

I'd just make all slots hold Stacks and the stacks would have a reference to the item definition and item instances list. If it's a non stackable item, it would just have 1 instance of an item in the list.

acoustic arch
#

oh well

teal viper
#

But if you really want to differentiate, you could make a stack inherit from an item instance so that you can pass them to the slot as an item instance.
ItemStack: ItemInstance

acoustic arch
#

i could just make them all a stack and limit the non stackable items to 1

#

which sounds simpler

#

like you said

teal viper
acoustic arch
#

ya

acoustic arch
teal viper
#

Yes. Instead of ItemData, it should be ItemStack

So thanks to your help here I got the new Inputsystem for local multiplayer running perfectly, the only problem I have now:

How can I allow the first player to navigate down to the start button? Currently both of the added players are contained in their little button test structure at the top but i'd like the first player to be able to break out of it and press start, any way to make that possible?

I attached a screenshot of how the "button container" prefab has the containment per-player configured

Hello, I am quite new to coding in of itself, and I would like to ask-
I have a script to select units written by a friend, and I would like to ask- what does it actually do? I would like to understand unity more instead of just constantly asking other people to help.

public class Unit : MonoBehaviour

{
public InputManager inputManager;
void OnMouseDown()
{
inputManager.UnitSelected(this);
}

public class InputManager : MonoBehaviour
{

public Unit selectedUnit;
public void UnitSelected(Unit unit)
{
    selectedUnit = unit;
}
slender nymph
#

first: !code
second: it uses the OnMouseDown method on the MonoBehaviour class which detects clicks on that object. when a click has been detected on that object is calls the UnitSelected method on the instance of the InputManager class that it has a reference to and passes itself. The InputManager's UnitSelected method just assigns the reference that was passed to it to a field on that class.

hey could anyone help me identify the problem? im getting null reference exception in this line
var collectionSlot = unitsCollectionController.collectionSlots.First(c => c.unitData.objectType == unitSlots[index].assignedUnit.objectType);

#

unitsCollectionController is assigned

slender nymph
#

unfold the Unit Slots collection there and make sure that it actually contains non-null elements

rare basin
#

well there are null elements, because the fill based on what units i choose

#

so for example right now in the deck i have 2 units, digger and north assasin

#

and if i add another it fills the [2] index

Hey, I have a bunch of blocks which each have a script (the same script _containing some variables. Now how do I get the information from a certain block into a different script? Im doing the inspector link method but it only allows me to manually select which block it takes the script from in the inspector. How can I make is so that I can just pick which gameobject does it take the information from? I hope that I wrote that clearly

rare basin
#

sorry wrong screenshot

verbal dome
#

It has null assignedUnits

rare basin
#

everything in the collectionSlots list is referenced, theere are no empty elements

verbal dome
#

Yeah but things inside those slots vould be null

rare basin
#

the unitDatas might be unll

verbal dome
#

And your Linq is trying to use those

rare basin
#

in the collectionSlots?

verbal dome
#

Anything there could be null

#

So yeah start by checking that

candid oyster
rare basin
#

everything looks good here

#

the unit data is referenced

#

and that's the only thing im using

# 
var collectionSlot = unitsCollectionController.collectionSlots.First(c => c.unitData.objectType == unitSlots[index].assignedUnit.objectType);
#

objectType is an enum

slender nymph
#

there are so many objects on that line that could potentially be null

rare basin
#

unitsCollectionController is referenced

#

collectionSlots is a list with no empty elements

slender nymph
#

how have you verified that any of this not null

rare basin
#

unitDatas are referenced inside the elements

slender nymph
#

and just looking at the inspector isn't really enough

rare basin
#

wdym i can see it's referenced

slender nymph
#

what have you done to verify your assumptions

rare basin
#

i can see it's referenced in the inspector

#

unitData for each unit

verbal dome
slender nymph
#

well then i guess everything is fine and your issue is solved

rare basin
#

and collectionSlots list doesnt contain any empty elements inside

rare basin
# 
    public void UpdateUnitUI(int index)
    {
        unitSlots[index].isAssigned = true;
        unitSlots[index].assignedUnit = PlayerDeck.Instance.unitSlots[index].assignedUnit;
        unitSlots[index].slotImage.gameObject.SetActive(true);
        unitSlots[index].slotImage.enabled = true;
        unitSlots[index].slotImage.sprite = unitSlots[index].assignedUnit.unitSlotSprite;
        unitSlots[index].plusEmptyImage.enabled = false;

        var collectionSlot = unitsCollectionController.collectionSlots.First(c => c.unitData.objectType == unitSlots[index].assignedUnit.objectType);
        if (collectionSlot != null)
            collectionSlot.hasBeenAdded = true;

        unitsCollectionController.RefreshCollection(index);
        UnitDeckPreviewController.Instance.AddUnitToPreview(index, unitSlots[index].assignedUnit);
    }
#

this is entire function

#

i have a UI preview of my current deck

# 
PlayerDeck.Instance.OnUnitAdded.AddListener(UpdateUnitUI);
#

and im triggering this function everytime i add a unit at specific slot index

# 
        Debug.Log(unitSlots[index].assignedUnit);

        var collectionSlot = unitsCollectionController.collectionSlots.First(c => c.unitData.objectType == unitSlots[index].assignedUnit.objectType);
        if (collectionSlot != null)
            collectionSlot.hasBeenAdded = true;
verbal dome
slender nymph
# rare basin

instead of using linq you should write a loop and do the check manually so that you can null check the relevant objects instead of just assuming that they are not null

rare basin
verbal dome
#

How do we know that PlayerDeck.Instance.unitSlots[index].assignedUnit is not null?

#

I agree that a loop will make it more debuggable

rare basin
#

Debug.Log(unitSlots[index].assignedUnit);

#

prints correct value

#

unitSlots[index].assignedUnit = PlayerDeck.Instance.unitSlots[index].assignedUnit;

#

and before debug log im doing this

#

so if PlayerDeck.Instance.unitSlots[index].assignedUnit; would be null

slender nymph
#

don't make assumptions. actually verify what is happening

rare basin
#

the debug.log would be null aswell

rare basin
slender nymph
#

well you're clearly not reading what i've written

rare basin
#

how is that an assumption?

#

PlayerDeck.Instance.unitSlots[index].assignedUnit; is not null

#

otherwise the Debug.Log will print null

verbal dome
#

What about unitsCollectionController or unitsCollectionController.collectionSlots or c...

rare basin
slender nymph
#

now what about the individual elements of the list and the objects you access on those elements?

#

stop making assumptions that they aren't null when there is at least one or more null object

rare basin
#

the only element that im checking i unitData which is SO and unitSlots[index].assignedUnit

#

and both aren't null and this is not an assumption xd

slender nymph
#

oh my mistake, here i was thinking you were using the First method from linq which will loop through the collection. i guess you aren't doing anything at all that could end up with a null object

rare basin
#

no reason to be passive agressive ;p

#

i've verified that nothing is null

verbal dome
#

Well you are being a bit defensive

slender nymph
rare basin
# 
        Debug.Log(unitsCollectionController);
        Debug.Log(unitsCollectionController.collectionSlots);
        Debug.Log(unitSlots[index].assignedUnit.objectType);

        foreach(var c in unitsCollectionController.collectionSlots)
        {
            Debug.Log(c.unitData.objectType);
        }
#

nothing of that

#

prints null

#

nothing else can be null

#

in this line
var collectionSlot = unitsCollectionController.collectionSlots.First(c => c.unitData.objectType == unitSlots[index].assignedUnit.objectType);

verbal dome
#

Do you have a duplicate of this script in the scene?

rare basin
#

Hey guys, creating a very simple ship game, 2D, where i shoot and destroy 1 enemy.. i dont know what could be wrong with my scripts.. have like 2 c# scripts 1 for enemy 1 for player, with just few lines, but i feel like when I am moving the ship sometimes there is a LAG on the input and even tho i already released the keys it continues to move for half a second like if it was a lag or something, any potencial reasons for that?

slender nymph
# rare basin no

try this and see if it prints any errors. if it doesn't then the issue does not lie here.

CollectionSlot collectionSlot; //obviously change this object's type to whatever it's correct type is
var collection = unitsCollectionController.collectionSlots;
for(int i = 0; i < collection .Count; i++)
{
  var slot = collection[i];
  Debug.Assert(slot != null, $"Element {i} is null on {name}", gameObject);
  var unitData = collection[i].unitData;
  Debug.Assert(unitData != null, $"Element {i} contains a null unitData on {name}", gameObject);
  if(unitData.objectType == unitSlots[index].assignedUnit.objectType)
  {
    collectionSlot = slot;
    break;
  }

        transform.Translate(Vector3.right * _speed * horizontalInput * Time.deltaTime);
        transform.Translate(Vector3.up * _speed * verticalInput * Time.deltaTime);
        } ```
#

I call it on void update

#

it works, but sometimes it just moves with a lag, and its so simple script.. imagine a complex one.. 😦

slender nymph
#

are you sure that it is actually lagging though? and not perhaps something just being stuttery, perhaps camera movement being stuttery?

#

if you think it is actually lag then you need to use the profiler to determine the source of any performance issues

I'm not sure what this is called. I want to have a function which takes some C# code, creates another new function, and sets this new function to a variable. For instance ```cs
public object Action;

public void CreateNewFunction(object action)
{
Action = action;
}

For now it's just at runtime but both in the longterm.

Hmm, so like the player can type the code or?

slender nymph
quaint thicket
#

Right now I just want to create some functions at runtime by setting them via a code-block instead of directly to functions. Later I'll do the playercode thing.

copper pumice
#

So basically you want a input field and then the text becomes code yeah?

#

Or did i missunderstand?

quaint thicket

So you want a runtime interpreter.

It's a pretty advanced topic. Are you sure you can handle it?

Hello guys, I am following an Udemy Unity course, still at the begining of the course but now I started to encounter a prob that even having EXACTLY the same code and setting as the teacher, he doesnt have a prob I have that SEEMS like its a LAG but not sure what could it be as sometimes when I am moving my ship and relase the key it continues to move in some direction or half a second.

Scripts:

Player: https://paste.ofcode.org/8G2N8UCrpJbHqDfjQyTR3T
Enemy: https://paste.ofcode.org/KQmAc5uHadHpAVLtw4XrR6
Laser: https://paste.ofcode.org/38jdzhzbSjuZfjSfZ9AUcfB

but I changed bat to GetAxisRaw

quaint thicket
#

I use the new input system, it detects a input action, and then I want it to run some function. The idea is that instead of making a function ahead of time, I'd put the functions code as part of a parameter, save it to a variable, and then run the variable-function instead of a normal function.

that's a delegate

I'll look that up. thanks everyone

also there is another prob.. when i limited the SHIP to not pass the lower border of the screen. sometimes RANDONLY and sometimes jut once.. it sticks there and wont get out for like some seconds.. what also doesnt happen with the teacher. and could be a lag also or whatever it is.. as A beginner see a code so small and game so small like that already having a prob that is hard to see where the prob is, damn.. imagine trying to create something a bit bigger.

slender nymph
#

the code you are using is fairly naive when it comes to ensuring the object stays within the bounds. it's very probable that the issue you just described also happened to the course instructor but they just didn't show when it happened

#

you'll probably also notice that your objects can move through colliders pretty easily and the instructor probably won't show that either. but that's because you are effectively teleporting the objects to specific places instead of moving them in a way that will automatically react to collisions like with physics

solemn fractal
# slender nymph the code you are using is fairly naive when it comes to ensuring the object stay...

yeah its a super beginer course.. so I imagine if he fixes everything if really there is a prob me as a beginer would be overwhelmed. Not sure if that would be the case. But all the tests he did I didnt see him having the prob at all. But could be just that he is hiding that as you say, no idea. Any ways its impossible for me to learn all now and I need to focus in some stuff. So for now maybe is just better to forget about this prob.. and focus on other stuff to learn that might be more important as a beginer.

solemn fractal
slender nymph
#

well if you can get a recording of what is actually happening like was suggested a bit ago by dlich that would be incredibly helpful for determining the cause

solemn fractal
slender nymph
#

you can build the game from the Build Settings menu

solemn fractal
solemn fractal
#

if I want to send that game to someone I need to send all that folder? or just the .exe?

image.png
slender nymph
#

you can use the profiler to profile the editor to see if it is actually causing a performance issue

slender nymph

slender nymph

the only exception would be if you were using Burst, it would create a folder that specifically says not to ship it

If i want to move my character by using rigidbody velocity, should i put the logic inside the Update method or FixedUpdate? Currently this is my script, but it is really buggy in regards to jumping

[SerializeField] private Transform groundCheckTransform = null; 
    [SerializeField] private LayerMask groundMask;
    [SerializeField] private float speed = 10f;
    [SerializeField] private float jumpSpeed = 10f;
    [SerializeField] private float turnSpeed = 10f;
    private Animator animator;
    private bool jumpKeyWasPressed;
    private float hzInput;
    private Rigidbody rb;
    private bool isGrounded;

    private void Awake() {
        rb = GetComponent<Rigidbody>();
        animator = GetComponentInChildren<Animator>();
    }

    void Update()
    {
        hzInput = Input.GetAxis("Horizontal");

        if (Input.GetKeyDown(KeyCode.Space))
        {
            jumpKeyWasPressed = true;
        }

    }
    private void FixedUpdate() {
        rb.velocity = new Vector3 (hzInput * speed, rb.velocity.y, 0);
        animator.SetFloat("Speed", rb.velocity.magnitude);
        transform.Rotate(Vector3.up, hzInput * turnSpeed);

        isGrounded = Physics.CheckSphere(groundCheckTransform.position, .3f, groundMask);
        Debug.Log(isGrounded);
        
        if (jumpKeyWasPressed && isGrounded) {
            rb.velocity = new Vector3 (rb.velocity.x, rb.velocity.magnitude, 0);
            jumpKeyWasPressed = false;
        }

    }
slender nymph
#

typically you would get your input in Update and apply physics inside of FixedUpdate

#

as for why it is buggy for your jump, why are you using the magnitude of the velocity for the Y velocity of your jump? that doesn't make a lot of sense

silent obsidian
#

Actually, I don't really know lol. would rb.velocity.y + jumpSpeed make more sense?

slender nymph
#

or just jumpSpeed

#

though i would personally use AddForce to apply the jump

silent obsidian
#

Okey, I see, it feels better with AddForce. Thanks!

buoyant knot
#

is there a way to check == true null?

cosmic dagger
#

huh?

#

which one: check true or null?

buoyant knot
#

like actual null null

#

not "destroyed object is null" null

cosmic dagger
#

it's still null . . .

buoyant knot
#

Would ReferenceEquals(obj, null) work?

cosmic dagger
#

☝️ that will work for c# objects . . .

buoyant knot
#

if you destroy a unity object, you can still plug it into a dictionary as a key

#

not the same as actual null, if that makes sense

cosmic dagger
#

unity does a bunch of internal checks for null on unity objects, so you have to use == null . . .

#

you can't use any of the c# null checks . . .

buoyant knot
#

well, I'm assigning null to represent actual nothing in this case

static cedar
buoyant knot
#

correct

#

I just wanted a way to distinguish

static cedar
cosmic dagger
static cedar
#

Is it because you can't really manually dispose a c# object?

buoyant knot
#

hold on, so obj is null, is different from == null?

#

trippy

static cedar
buoyant knot
#

anyway, I made my first public git repo class

cosmic dagger
# buoyant knot I just wanted a way to distinguish

It's hard to distinguish between fake null and real null. You can have a bool on a MonoBehaviour class that marks it as destroyed but you can't access it if/when the UnityObject does become null . . .

cosmic dagger
static cedar
#

I guess that's a pretty annoying limitation for cases like that. UnityChanThink

teal viper
#

For all intents and purposes, a destroyed object should be considered as null. There isn't really a need to make distinction.

buoyant knot
cosmic dagger
#

I'd just check for null and call it a day. It's considered null when destroyed anyway . . .

buoyant knot
static cedar
#

Btw, casting a unity object to an interface and then comparing it is a foot gun ye? UnityChanThink

buoyant knot
#

uhhh.... maybe lol

#

because the interface wouldn't have == overridden

static cedar
#

Yeah.

static cedar
buoyant knot
#

wdym weak references?

static cedar
slender nymph
#

WeakReference wouldn't account for destroyed objects though

static cedar

Yeah sadly.

Hello! I have 2 questions, let's start with the first one. My unity engine just locked my cursor, so I can't make colide boxes or choosing items on the screen with my mouse anymore. It can be fixing by just creating a new project, but I would like to continue with my existing one. is there anything I could do to fix it? Thank you before hand blushie

slender nymph
#

if your cursor is actually getting locked, then some code somewhere in your project is locking it via the Cursor.lockState property

U can try global word search on ur IDE. UnityChanThink

shell zephyr
#

Yes, but I can use it to choose assets in project or inspector, but not on screen

#

That's weird :(

slender nymph
#

is the cursor locked or not?

#

keep in mind that it being locked is not the same as it being visible but not able to click anything

so it's just affecting Game view? is it that you cannot click on buttons and other UI objects?

shell zephyr
#

Nop, I'ts no affecting the game. but it's not allowing me to add any coliders or move any objects

slender nymph
#

what? you just said you can click on things in your inspector and scene, no?

#

can you record a video of whatever is happening? because you can't seem to describe what is actually happening without contradicting yourself

also is this even code related?

How would you guys handle a character rotation based on the horizontal input?

    private void FixedUpdate() {
        rb.velocity = new Vector3 (hzInput * speed, rb.velocity.y, 0);
        animator.SetFloat("Speed", rb.velocity.magnitude);

        Quaternion startRotation = transform.rotation;
        Quaternion targetRotation = transform.rotation * Quaternion.Euler(0, hzInput * turnSpeed * -1, 0);
        
        // pseudocode ?
        // if (transform.rotation.y < 90 || transform.rotation.y > -90) {
            transform.rotation = Quaternion.Slerp(startRotation, targetRotation, .5f);
        // }

I managed to get my character to rotate but I'm struggling to find a way to only let it rotate if rotation.y < 90 || rotation.y > -90

slender nymph
#

search "clamp rotation" or "clamp camera" for examples of how you can clamp it.

#

but basically you keep a float that you add/subtract to when you want to rotate the object. clamp that, then apply that using Quaternion.Euler to construct a quaternion from your angles and assign it to the object's rotation

#

do not attempt to clamp the transform.rotation values as they are not in degrees, nor the transform.eulerAngles values as they are interpreted from the quaternion at the time you access them and may not be exactly what you would expect them to be

is this a good way to assign tmp text objects cuz ik there is another way and this was isnt seeming to work for me?

That's a good way to assign any variable. Setting it directly is always going to be faster than getting it some other way

Hello! It's asking me to add something there, but I don't understand what exactly Unity wants. I tried with scripts and animations, but It's not accepting them

Like, an Animator controller. Not a script. Not an animation

Animator

It's a component

You can think of it as an Animation Manager or smth.

You can look it up. There's plenty of tutorials on it

Idk the whole context. But yea the orange box is the state that will be entered by default. You might(?) not technically need it, since you could transition to a non default state from the Any State node based on some condition - but idk how an animator behaves whose controller doesn’t have an active state

I’ve never not had a default state

Hey all. I have this move method. My game starts paused so I need to zero only the forward velocity. Since these are local variables. I could not seperate them and use individual axis. Can someone help me out

If it's important, show us/yourself.

ivory bobcat
# flat slate

Try more useful logging instead:cs Debug.Log($"{name} was touched by {trigger.name}", this);

flat slate
#

instead of?

ivory bobcat
#

Instead of what you had prior

flat slate
#

instead of the log: hide, show, or istoched, isnttouched?

ivory bobcat
flat slate
#

these are all logs

ivory bobcat
flat slate
#

ye i know but what do i have to replace with that?

#

which log code

ivory bobcat
flat slate
#

ok

swift crag
#

the example Dalphat gave you says "was touched by", so..

ivory bobcat
flat slate
#

ye

#

ok

#

it even says that it touches

#

but the button doesnt show up anyways

ivory bobcat
#

What becomes highlighted when touch occurs?

#

Something should become yellow when you click the log message

flat slate
#

wait

#

the player

#

as it should

ivory bobcat
#

So this part is working fine.

flat slate
#

ye

#

the problem is in the "gameObject.setActive(true);"

#

but i dont know why

ivory bobcat
#

Meaning the fault has to do with your IsTouched script/object

flat slate
#

so what should i do

ivory bobcat
#

Does "Show" ever print?

flat slate
#

no

#

and hide does just 1time

#

so just in the start not when the player doesnt collides anymore

ivory bobcat
#

If not, it doesn't ever think "the player" it's referencing is ever touched.

flat slate
#

ye

#

wait

ivory bobcat
#

Meaning "the player" it thinks is the player, isn't the one being touched

#

Or IsTouched is never called again

#

Since the code shown are excerpts, we aren't able to know the behavior that you've designed for it - the more important stuff.

flat slate
#

wait

#

i can try soemthing

ivory bobcat
#

It's likely possible that it's one of the two above or that you may have secretly set to the bool to false elsewhere prior to checking etc

#

The issue isn't related to the code shown above - we weren't given enough info.

flat slate
#

i can look for it

#

maybe the problem is with the function itself

ivory bobcat
flat slate
#

but there is just one player

#

istouched have to be called again bcs its in the update method

ivory bobcat
flat slate
#

ye i know

#

but what should i do then

ivory bobcat
#

Is the console spamming hide/show?

flat slate
#

no

#

just in the start it says 1time "hide"

ivory bobcat
#

Make it spam it or occur once with properties etc?

#

Spam would be referring to the method being called in Update - apparently it's not according to the video

flat slate
#

ye it is

ivory bobcat
#

It wasn't prior

flat slate
#

in the video the "hide" method is being called 1 time

ivory bobcat
flat slate
#

ye i know

#

but it doesnt

#

but why

ivory bobcat
#

So that means it isn't being called in Update

flat slate
#

but it is

buoyant knot
flat slate
ivory bobcat
flat slate

#

!code

eternal falconBOT
flat slate
#

this is the whole script

ivory bobcat
#

Is it spamming the console now?

flat slate
#

no

polar acorn
# flat slate no

Then either:

  1. You have an error
  2. This object is destroyed or disabled
    or 3. It is
ivory bobcat
#

If not, did you save the script? Are there any compilation errors? Are you not using the script (implies you've got backup scripts and aren't using the correct script)?

flat slate
#

wait

ivory bobcat
#

Is the script on an inactive object?

#

Update isn't called on inactive objects.

flat slate
#

yes its inactive

#

okay i know the problem thanks

buoyant knot
#

just a side note: SCREAM_CASE is only normally used for consts

#

if I read PLAYER, I assume that is a const, but it isn’t. It’s a field

Not necessarily a coding question, but I like you guys better than the other channels:

Doing a platform adventure game with zone transitions back and forth.

Right now I only have a few, I'm setting up each full zone as a prefab that I instantiate at a pre-defined point.

My question is what's the best way to handle instantiating each new zone? Should I lay it out as one big world, each zone with its own point to spawn in when needed?

Should I alternate between a few points? Loading and unloading?

Hello fellow devs.
How can I prevent diagonal movement?

 private void Update()
    {
        inputMove.x = Input.GetAxis(c_horizontal);
        inputMove.y = Input.GetAxis(c_vertical);

        if (inputMove != Vector2.zero && moveRoutine == null)
        {
            var dir = new Vector3(inputMove.x, 0, inputMove.y).normalized;
            Debug.Log(dir);
            moveRoutine = StartCoroutine(LerpPosition(dir, duration));
        }
}```

Yea, I'm trying to find examples, but I don't really know what I'm looking for yet.

I'm thinking alternating between 2 spawn points might work best as that keeps the overall size of the map down, but might be tricky with different sized zones

Check if your X value is nonzero. If it is, set dir to that X value.
If it's zero, set dir to that Y value.

Or vice-versa

# polar acorn You're still using two values for `dir`

something like this?

var horz = inputMove.x > 0 || inputMove.x < 0;
        var vert = inputMove.y > 0 || inputMove.y < 0;

        if (inputMove != Vector2.zero && moveRoutine == null)
        {
            var dir = new Vector2();

            if (horz && moveRoutine == null)
            {
                dir = new Vector3(inputMove.x, 0, 0).normalized;
            }
            else if (vert && moveRoutine == null)
            {

            }

like getting the same effect as a gameobject with rigidbody2d and collider2d with a bouncy material atached

but instead I want to replicate this behaviour on script with a trigger collider

I have done this in the past with a OnCollisionEnter2D but I cant seem to figure it out with trigger

bouncing off a wall btw

just use raycasts

can I just create the raycast itself when the object gets triggered by the wall or should I call it every frame checking if it is hitting the wall

cosmic dagger
uncut dune
ivory bobcat
#

If you're using physics trigger, you should be able to just create your direction given the difference in position of the two object and find the necessary normal thereafter

uncut dune
#

not sure if it would work

ivory bobcat
#

Convert coordinates to the appropriate space 🤷‍♂️

uncut dune
#

and I did something like this

#

but how would I find the trigger coordinates

ivory bobcat
#

I'm assuming you meant collision info etc

uncut dune
#

I guess so

ivory bobcat
#

Whereas this time you're only given info about the collider and have to use some math to obtain the direction yourself

collisionCoordinates - transform.position

now what do I do with it

because from what Ive seen I cant even find the collision coordinates with trigger

If you're wanting the normal to some surface, consider raycasting for ease of life on the trigger event

yup thats what I was talking about, so I can know to where the object should actually go

isnt raycast expensive tho?
