Privataly settable

safe hull
#

ah, ok

#

alright, Im so used to java

#

that looks good

summer stump
#

You still cannot do new

#

You can't new an enum

safe hull
#

oh yeah

#

lol

#

do I just get rid of that?

summer stump
#

public ObjectType objectType { get; private set; } = ObjectType.Stone;

If you want a default

#

It should default to stone already though. I think default is 0

safe hull
#

ah so that just makes it appear as a dropdown, which can change

#

sorry for the inconvienience

summer stump
#

You may need to do a [field: SerializeField] attribute above it.
Unless you mean you already see the dropdown?

safe hull
#

yeah, I just noticed that

#

looked up enums it said that was necessary

safe hull

Great!

Hello, I'm trying to make a movement system in the style of the collide and slide algorithm but the walls kill all velocity and the ramps make you much faster, is there anything obviously wrong with my code?

why is Coroutine is so buggy when placed in FixedUpdate, I created extra animations for the slime to leap toward the player but when I try to execute it in Coroutine, it is just terrible. The amount he dashes is usually half the Distance i set, or maybe even one tenth, or zero. I use virtually the same code in fixedupdate with SlimeDash a new State, it works just fine

I'm using the class reference method but the variable value is not being retained between classes

    {
        PathContext pathContext = new PathContext();
        while (pathContext.TotalTimeElapsed < chaseDuration)
        {
            yield return _pathfinder.MoveAlongPoints(pathContext, _pathfinder.GetPoints(target.position), RecalculateSpeed, _moveSpeed);
            Debug.Log(pathContext.TotalTimeElapsed);
        }
    }```
I'm modifying its value on the pathfinder class but when it returns the value is the same

            if (pointIndex >= points.Length)
            {
                targetVelocity = Vector3.zero;
            }
            else if (Vector3.Distance(transform.position, points[pointIndex]) > .1f)
            {
                targetVelocity = points[pointIndex] - transform.position;

            }
            Move(targetVelocity, moveSpeed * Time.deltaTime);
            pathContext.PathTimeElapsed += Time.deltaTime;
            pathContext.TotalTimeElapsed += Time.deltaTime;

            yield return null;
        }
        yield return null;

    }````
teal viper
#

Hmm

abstract finch
#

Debug.Log is returning the same value 0.1012646

#

which is the duration inside movealongpoints so it makes sense

#

its not retaining the modified value in the class called

teal viper
#

I feel like there's some confusion with the coroutine yields.

abstract finch
#

let me fix some

#

you mean the yield return null?

teal viper
#

No. With yield return AnotherCoroutine.

abstract finch
#

is there an alternative? this is the only way i know how to run another coroutine within one

teal viper
#

For starters debug what's going on. Use the debugger to step through the code or add more logs.

abstract finch
#

ok

wintry quarry
teal viper
#

I kinda feel like the nested coroutine just only does one loop before finishing.

abstract finch
#

I just tried declaring the time elapsed value on the second coroutine, whats happening is the value of TotalTimeElapsed is not being saved when being modified in the other coroutine

worthy chasm
#

i finished the brackeys tutorial and its good but glimpses over the coding too fast, whats a better series to follow with a lot of focus on coding?

abstract finch

I had to reset this variable every time it entered the second coroutine

#

in my game i have a grappling hook and right now im using a lienrenderer to draw the line between the player and the end of the grappling hook but i want to make the line look like a rope and not just a renderer line. so i made a rope sprite but how should i go about making a rope sprite that can dynamically change sizes depending on the distance between the player and the grapple end and that conencts the 2.

worthy chasm
#

why is he multiplying the mouse movement and not just adding it to the rotation, can someone explain the logic?

eternal needle
worthy chasm

can u tell me a better tutorial

eternal needle
worthy chasm
#

i watched another tutorial and it also u ses time.deltatime

#

what should it be instead

eternal needle
# worthy chasm i watched another tutorial and it also u ses time.deltatime

i believe you can just exclude the Time.deltaTime, most tutorials do this because one guy did it and every tutorial is a copy paste of each other. Most people who make beginner tutorials arent very good themselves.
As for your question about "not just adding it to the rotation" im not sure what you mean, .Rotate will rotate the object

timber tide
#

I was looking that up too and I see a lot of tutorials multiplying by deltatime

#

but I swear I've had it working without it

#

oh right doesn't a brackys video do that

languid spire
#

From the GetAxis docs

image.png
#

I do wish people would read them

eternal needle
timber tide
#

Ah, ok GetAxisRaw is frame independent, but you have to do your own lerping if you want to smooth it, but GetAxis seems to already do most of that work for you.

#

If I'm understanding correctly

#

So I guess it's just people getting mixed up between the two

#

Mouse.current.delta.ReadValue(); would be considered the raw values too

north kiln
#

Scaling by deltaTime doesn't smooth something that is already frame-rate independent anyway, it just ruins it

#

you would need to actually perform some sort of filter to smooth

how can i fix this? Find is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'KeyClicks' on game object 'KeyHandler'.

what do you not understand about that message?

what i need to do to fix it

im not sure

you need to understand the message and do what it tells you to do

it says to call it in start

no it does not

then what do i need to do

Item equippedItem = equipmentSlot2.GetComponentInChildren<Item>();
does this always throw an error if there is no Item?
should I use var instead?

keen dew

var just means that the compiler guesses the type from context; the end result is exactly the same

In my game enemy attacks if float attackRandom > attackProbability. I want to increase the chance of attack steadily on runtime. But Im not sure how to keep incapsulation here. I dont think making attackProbabillity public is a good idea. Score is saved in GameManager and attackProbability is stored in enemy script. How do i keep attackProbabillity private?

#

So, depending on the score, attack probabillity should be increased

timber tide
#

You can consider reading from GameManager's score from where attackProbability is calculating

bold nova
#

So, making score public?

timber tide
#

You can always read publicly if you want to do that, and set as private

bold nova
#

Attack method is realized throught InvokeRepeating and i thought maybe i should += to attackProb some multiplier that is calculated based on score until probabillity reaces 0.6

bold nova
#

public get, private set

#

thanks!

timber tide
#

Yeah, there's a bit more to it when it comes to reading references publicly, but if it's some sort of value type then it's as easy as that.

Hi guys, how are you ?
I'm trying to add an onclickFunction on a Instantiated button. I know the add listener system, but since my button is not instantiate at the beginning of the game, i dont know how to do that :/

Why would it matter when it's instantiated?

safe hull
#

is it a prefab?

I still don't see how that prevents you from adding the listener

So you ask how to post code in another channel and then post it incorrectly here. Why?

keen dew
safe hull
# 
                ObjectData objectData = interacted.GetComponent<ObjectData>();
                KeyBindType.text = objectData.keyBind.ToString();``` wouldn't this get the script component from the raycasted object, and then take the KeyBind variable and put it into the string?
#

I debuged it and am getting the error right after:

keen dew
#

Which one is line 30?

languid spire
timber tide

debug it all

keep in mind the Debugger can be good for some of these things. Debug mode lets you peak into the contents of all variables up to your breakpoint.

Hi!

I know I'm having amoment where I'm being very dumb, but my brain cannot currently figure this out. Why can't the GameManager see exitpermitted() ?

I'm doing a Uni assignmkent, but the professor isn't available due to ahving covid.

image.png image.png
timber tide
#

what's the error

safe ore
#

exitpermitted doesnt exist in current context

languid spire
polar acorn
safe ore
#

exitpermitted() is in the ExitPossibleIndicator class within a script document of the same name. I thought I'd be able to reference it in the GameManager since it's all set to public.

languid spire
#

you need to learn some c# basics

polar acorn
#

You have to call that function on an instance of ExitPossibleIndicator

#

You have to tell it which of those you want to call the exitpermitted function on

tawdry nymph
#

I am currently working on a boss and i have 3 attacks for it, spray which works fine, bulletwall, which works occasionally but sometimes doesn't register as completed, and smash which doesn't work at all. I've been having trouble with this for a while now and I can't seem to figure out the problem. this is the script attached to the Object: https://gdl.space/xiyezuroye.cpp

rare basin
#

would fit percetly in there instead of doing everyhing in one big function in Update()

#

what if you will have 10 attacks, you will need to make 10 if/else statements and a huge code wall

safe ore
# polar acorn https://unity.huh.how/references

Thank you, and sorry for doubt you but I wanted to make sure you had all of the information.

This is exactly what the professor wants. I am stuck on the very end, trying to call the thing from another script. I want to make sure this still applies. We've only been coding in Unity for 4 weeks, a couple of hours every Monday so I'm not used to this yet.

I'm making a simple class (Bounds2) which is basically Bounds but for 2D.
I want separate constructors to make by min and max, and another to specify by center and size. But both would have the same arguments. Is there a way to do this with constructors? or is the cleanest way just to make a static method that makes a new Bounds2

How do I make my app's UI work with all screen sizes? I've got my Canvas on Scale with screen size but my text boxes will look great on one device and then when I switch to an iPad Mini 4 or something like that, the text boxes are off the screen. My UI is currently a couple of input fields that I'm using for testing i.e. there is nothing fancy

undone rampart
modest barn
#

@undone rampart how do you think I could implement code that checks for overlapping text boxes and reduces the size so they fit correctly? That will be an issue too

Great, I'll check that out. Thank you.

Edited a script while in play mode accidentally. How can I fix?

#

The referenced script (Unknown) on this Behaviour is missing!

wintry quarry
timber tide
#

those are kinda tricky to find sometimes

modest barn
#

There are no references in the scene, the script that was edited is instantiated by another script

timber tide
#

may have edited a prefab

wintry quarry
#

Check the prefab

modest barn
#

Pretty sure I don't have a prefab

wintry quarry
#

What are you instantiating then?

modest barn
wintry quarry
#

The error is talking about a broken MonoBehaviour reference

#

You wouldn't be using new for a MonoBehaviour

#

If you are that's a problem in and of itself

modest barn
#

Yeah that's what I was confused about

#

The only script that I edited during play mode

#

Was a script that does NOT inherit from MonoBehaviour

#

So I don't understand how there's a broken reference there

#

But I restarted Unity and all is well so I'm not sure...

rare basin
#

you can't really make changes in the code during playmode

#

that can lead to many random errors

modest barn
#

Yeah I know, just thought I had stopped the game, but I guess not

rare basin
#
  • dont modify scripts during playmode (even at paused)
  • dont refresh the project during playmode
  • dont make new scripts, dont delete any scripts, don't do anything that requries re-compiling the scripts

Hey guys, is there a way to reset the Time.time? I am trying but it is not allowing me saying its just readable. And I am having a problem where if you die in the game, you go to the main screen again, and when you press play, the Time.time is not ZERO again, its the same as before and that is messing with stuff..

Time.time is the number of seconds since the application began running. You can use it for differences, but should not use it for absolute values

Closing the game and starting it will reset that value

Resetting it artificially would defeat the purpose of it

Hello! please help me in creating a code, I have no idea on how I can display data in a unity scene from firebase, I know how to get data from unity to firebase but I don't know how I can display it on my unity scene.

please provide example code

And boom

Thank you so much to the both of you! I'll try them! 😊

and when I do that, this happens

You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed. MonoBehaviours can only be added using AddComponent(). Alternatively, your script can inherit from ScriptableObject or no base class at all
UnityEngine.MonoBehaviour:.ctor ()

I still don't fully follow what you mean by that

delicate notch
#

Objects are created by classes

polar acorn
#

Do you mean Object, the class, or object the concept

#

An object is an instance of a type, and classes are types

delicate notch
polar acorn

Okay, so yes, an object is a concrete representation of data defined by a class (or struct)

be careful, in Unity, Object and object are 2 different things

This how to keep this script alive

polar acorn
delicate notch
#

When switching scenes

delicate notch
languid spire
#

look at DDOL

delicate notch
#

what?

polar acorn
#

That's how you tell unity that

languid spire
#

Dont Destroy On Load

delicate notch
#

but when i do that

#

Would I have to create some sort of loop

#

to allow the script to run well again when press play again

#

or Does it allow specific scenes for it to live

polar acorn
#

What?

languid spire
#

you want to keep the Coroutine alive or the script alive?

polar acorn
#

What do loops have to do with things?

delicate notch
#

basically

polar acorn
#

regardless of DDOL

delicate notch
#

Ye so I just watn this script to live for 2 scenes then it dies

#

The whole thing

polar acorn
#

Then use DDOL to keep it across a scene load then manually destroy it when you're done with it

delicate notch
#

I see

#

DDOL is the singleton thing?

#

jsut to confirm

no

Evenin' all. soooooo, I'm having a bit of a brain issue figuring out the logic on this script.

What I want it to do is for the 'end point' of the linerenderer to move back to its origin ( left side of the screen, pink character), but I can't seem to figure out code.

Could anyone point me in the right direction please?

Hi i have this code and i want the code to spawn a prefab in like 3x3x3 or 6x10x8 like you choose how many to spawn and i am getting stuck my code is under

 [SerializeField] private GameObject boxPrefab;
 [SerializeField] private float boxWidth = 1.0f;
 [SerializeField] private float boxLength = 1.0f; 
 [SerializeField] private float boxHeight = 1.0f; 
 private float amountToSpawn;

 void Start()
 {
     SpawnBoxes();
 }

 void SpawnBoxes()
 {
     if (boxWidth > 1 && boxLength > 1 && boxHeight > 1)
     {
         amountToSpawn = boxWidth * boxLength * boxHeight;
         while (amountToSpawn > 0)
         {
             // Code to spawn them like 3x3x3 or boxWidth x boxLength x boxHeight
             amountToSpawn--;
         }
     }
     else
     {
         Instantiate(boxPrefab, transform.position, Quaternion.LookRotation(Vector3.forward));
     }
 }

3 nested loops

ruby python
eager elm
# craggy lava may i ask why? 
for (int x = 0; x < width; x++)
{
    for (int y = 0; y < height; y++)
    {
        //Instantiate here and set position to (x, y)
    }
}```
Then it will Instantiate width * height objects.
summer stump
#

The nested loops for the 3x3x3 would run like this with their indexes

0, 0, 0
Then 0, 0, 1
Then 0, 0, 2
Then 0, 1, 0
Then 0, 2, 1
Etc

It would give you all 3x3x3 coordinates

it spawns something but there is too many now my script looks like this

    {
        if (boxWidth > 1 && boxLength > 1 && boxHeight > 1)
        {
            amountToSpawn = boxWidth * boxLength * boxHeight;
            while (amountToSpawn > 0)
            {
                for (int x = 0; x < boxWidth; x++)
                {
                    {
                        for (int y = 0; y < boxHeight; y++)
                        {
                            for (int z = 0; z < boxLength; z++)
                            {
                                GameObject boxToSpawn = GameObject.Instantiate(boxPrefab);
                                Vector3 pos = new Vector3(x * boxWidth, y * boxHeight, z * boxLength);
                                boxToSpawn.transform.position = pos;
                            }
                        }
                    }
                    amountToSpawn--;
                }
            }
        }
        else
        {
            Instantiate(boxPrefab, transform.position, Quaternion.LookRotation(Vector3.forward));
        }

Also, you have an extra scope in there
The curly braces

Right after the for loop with x

Kinda works

but the spaceing is because of this cs Vector3 pos = new Vector3(x * boxWidth, y * boxHeight, z * boxLength); then the grid is 3 from each pilar

since the newText in inspector is empty so unity passes an empty string each times it calls it

You do NOT want to upload a lot of the stuff you are pushing

show the newText in inspector
i am pretty sure it is an empty string

the newtext is serialized so unity passes the value in inspector when it calls this method

yes, empty string

You probably want to use the dynamic version of the function

instead of passing in a hard-coded empty string

how do i do that

which passes the value of the input

how do i know if the .ignore file is working??

should it be a txt documnet?

wintry quarry
#

wdym?

#

The name of your .gitignore file is correct

fickle geyser
wintry quarry
# fickle geyser

The thing that says "Text Document" is just Windows classifying the file based on some heueristic

#

it's completely meaningless/irrelevant

fickle geyser
#

well

your os classify it as text document

it still shows me 13k files

what does

#

Commit the gitignore file 🤷‍♂️

fickle geyser
#

ah..

summer stump

Did you commit anything else yet?

If so it's not named properly

it should just be .gitignore

can anyone tell me how i can check if a function could be called in unity or it throws an error. in c++ you just do if( function() ) but idk about c#

scarlet tiger
queen adder
#

wdym

scarlet tiger
#

wdym by check if it can be called

queen adder
#

if it throws an error

scarlet tiger
#

you can catch the error

#

using try {} catch(Exception error) {}

queen adder
#

for example if im trying to reach an item in a list that doesnt exist and it returns the outofbounds error, i wanna check that

queen adder
scarlet tiger
queen adder
scarlet tiger
#

so for you it would be

try
{
  function();
}
catch (IndexOutOfRangeException e)
{
  //do something on fail
}
#

in general though you'd put checks in to prevent the throw

#

so checking index is valid before trying to access

queen adder
#

wait

#

how will it be in the case of this error

image.png
scarlet tiger
#

can you show the code too

#

generally you want to avoid try catching throws in the first place

queen adder
#

wait i dont think i need to do catch {}

scarlet tiger
#

I know, but show the current code you have

#

question manager around line 46

queen adder
#

i tried the c++ method, but its not good, imma implement it with try{}

image.png
queen adder
scarlet tiger
#

if (questionContainer.transform.childCount > index + 1 && ...) nextButton...

#

I think that should prevent the error

#

There might be a space or other "invisible" characters at the end of that string

polar acorn
short hazel
#

Well actually the issue is that you're using a TextMeshProUGUI to interface with an input field, that's incorrect

queen adder
short hazel
#

The field should be of type TMP_InputField

true pasture
#

oh

#

lemme try that real fast ty

polar acorn
#

TMP_InputField adds a non-print character that isn't stripped with Trim(). You can manually cut it with:
.Replace("\u200B", "")

#

Or use the input field directly

scarlet tiger
#

otherwise you are asking for an index that doesnt exist

true pasture
#

okay ty guys that fixed it

queen adder
scarlet tiger
#

ok lol, why are you having negative indexes?

queen adder
#

i can do that also

scarlet tiger
#

add a check to make sure it's greater than 0 too then

queen adder

im so dumb lol

Is there a way to use GameObject.Find() for inactive game objects?

wintry quarry
calm coral
wintry quarry
#

You should avoid GameObject.Find in general for many reasons, including this

wintry quarry
calm coral
wintry quarry
#

GameObject.Find is very inefficient

#

it's also fragile, as it depends on object names which can change at any time in development

#

The preferred way is a direct reference in the inspector.

#

But again it depends on the context

calm coral
# wintry quarry GameObject.Find is very inefficient 
void Reset()
{
    GameObject.Find("Virtual Camera 1st person").TryGetComponent(out a1stPersonVirtualCamera);
    GameObject.Find("Virtual Camera 3rd person").TryGetComponent(out a3rdPersonVirtualCamera);
}
```Yes, it is inefficient but I'm running it just once, not in `Update()`. The thing is if game object is disabled it can't get its component and I have null reference exception
#

It's like null.TryGetComponent(out a1stPersonVirtualCamera); and that's not going to work

slender nymph
#

so null check the result of the Find before calling TryGetComponent on it

calm coral

So I was wondering if I can do something in case if game object is disabled

    }

    private Texture2D GetSteamImageAsTexture(int iImage)
    {
        Texture2D texture = null;

            byte[] image = new byte[width * height * 4];
            isValid = SteamUtils.GetImageRGBA(iImage, image, (int)(width * height * 4));

            if (isValid)
            {
                texture = new Texture2D((int)width, (int)height, TextureFormat.RGBA32, false, true);
                texture.LoadRawTextureData(image);
                texture.Apply();

# wintry quarry why don't you just: - do this once when they're still active and save the refere...
  1. Well, the thing is if one camera is activated then the other one is deactivated and vice versa. So one of cameras is always disabled by default.
  2. Uh, that's going to make more mess I guess aniblobsweat I'd have to create a new class to store references for deactivated game objects, it's rather faster to just manually assign them in inspector

I was wondering if there's a way to convert Instance ID to game object, something opposite to GetInstanceID();

wintry quarry
#

make a script that references both of these obejcts, directly, through the inspector

#

Then you can do whatever you want with the references

#

share them with other scripts, etc.

Where exactly is it crashing? Because that code does nothing apart from running Start() when the game starts.
Do you have an exception occurring somewhere? You should post its stack trace here

In an if, when checking collision, how do I check if the first object collides with any object in the second object?
The code is this:

if (Collider2D.Equals(gameObject, deletionAreas))
{
    Destroy(gameObject);
}
````deletionAreas` is a List.
wintry quarry
#

Can you be more clear about what you're trying to do?

#

You want to check if a certain object is contained in an array?

#

What types of obijects are we talking about?

#

GameObject? Collider2D?

#

What is the type of the array?

wintry quarry
pliant oyster
#

The code is for a bullet. I have two squares outside of the screen. I want the bullet to delete itself when it touches it (or an enemy/player, which I will add later).

wintry quarry
#

it's just checking if two object references refer to the same object... sort of, in a really wrong way.

wintry quarry
pliant oyster
#

In the if, or as a new method?

polar acorn

details depends on which style of input handling you're using

I just realized, I can do that without using colliders by just doing a "if bigger than x or smaller than y" check

Are you using InputActionReference?

polar acorn

#

ahhhhh

#

is PlayerInput a object that holds methods useful towards input reading

wintry quarry
queen adder
#

oh

#

i'll do that

#

i tried starting from unity's manual but it wasnt very helpful

nimble inlet
#

ok first I'd like to ask why " GameObject playerObject = GameObject;"
=> trying to hover a gameobject from scene onto inspector doesn't work. (type mismatch of somekind?)

image.png
#

maybe the syntax is wrong (that used to be from find object with tag. ) but couldn't really assign that eithe.r

polar acorn
nimble inlet
#

yeah that should be. it wasn't though, there was this that checked null

image.png
#

^tagging is bad but I was in a hurry and couldn't assign shit. xd

#

how should I do it?

polar acorn
nimble inlet
#

this tag I think doesn't find its way home, and it's the right title.

short hazel
#

You talked about:

hover a gameobject from scene onto inspector
So are you drag-dropping? Or are you referencing it from the code?

nimble inlet
#

drag dropping.

short hazel
#

Because when it refuses to drag-drop into an object in the scene, it means the thing you're trying to drag-drop is an asset (prefab) that is not in the scene, and that's not allowed

nimble inlet
#

I'm trying to drag an object from the hierarchy in the scene onto a prefab. :C

#

maybe that's not allowed.

short hazel
#

Yes, because there is no guarantee the scene will exist when the prefab exists

nimble inlet
#

right. but I do need the link from that object to the prefab (I'm using the prefab to spread a script that needs the player location).

#

maybe I'm going all about this wrong.

short hazel
#

The code that Instantiates the prefab will have to pass the references you need at runtime, fully from the code, then

nimble inlet
#

ugh.

rocky canyon
#

spawn it, set it, forget it

nimble inlet
#

right now it adds the script that asks for the reference to the object. That script needs that link, but I don't think I can assign things to a script from the inspector, and tagging is bad (and didn't work...)

rocky canyon
#

there's other alternatives

#

but you'll have to assign it during runtime..

#

the only other alternative is to have the stuff u need packaged into the prefab already

nimble inlet
#

I have the script packaged in the prefab, but that's one I cannot drag to. otherwise I do not know what to add to it. x-x

short hazel
#

Who talked about finding, when Instantiate returns the object that was just created?

GameObject inst = Instantiate(prefab, pos, rot);
inst.GetComponent<SomeScript>().thing = something; // injection of the reference
rocky canyon
#

no the things you drag must also be inside hte prefab

#

or u assign it after the fact ^

nimble inlet
#

aagh. I'm too tired for this x_X

nimble inlet
rocky canyon
#

heres a reference manager i use

image.png
nimble inlet
#

taking some of its component.

polar acorn
rocky canyon
#

in start i find all my references.. during the loading screen

polar acorn
#

You want to set the variable of the object you just spawned

nimble inlet
rocky canyon
#

then afterwards they're assigned so i dont need to call expensive find calls or w/e

nimble inlet
#

amaznig

rocky canyon
#

just that once

nimble inlet
#

shit I should've done that. it's a little late now.

rocky canyon
#

note, thats just 1 method.. and it does use find calls.. which somepeople don't ever use

nimble inlet
rocky canyon
#

in my experience i use them in start and awake functions (just once) and its been a pretty decent system

polar acorn
#

and then pass it to the spawned object

nimble inlet
#

object spawning prefab aka the enemyspawn manager?

#

noooo x_x

#

I can't follow.

#

maybe just scrap that whole thing. it's getting super late.

polar acorn
nimble inlet
#

it would truly take some time to get to the bottom of this/understand the thing fully

#

this script worked a while ago

#

it stopped working out of nowhere with basically no changes. x_x

bleak pasture
summer stump
#

It's for instantiating copies

#

You CAN do it across scenes, but they are useful even in one scene

bleak pasture
#

I thought I would only do a ui control in one scene, prefab it and then reuse it in other scenes...

summer stump
bleak pasture
#

so I dont have to redo that ui control in a canvas over and over again

summer stump
#

Just use DDOL

Oh, maybe I misunderstood

#

You mean copy the same canvas/ui into multiple scenes? That makes sense

#

I thought you meant copy the current state of the ui to a prefab at runtime, then instantiate that state in a new scene

bleak pasture
#

Like the ui control is actually a text with separator and part of the text is clickable etc. text is dynamic (so monobehaviour) and I want to use the whole thing as a control in multiple scenes. SO I thought of making it a prefab so the monbehavior follow around to manage the dynamic text as well so I can use the whole control in multiple scene

#

And no it's not to copy the state it's for code/gameobjects reuse

summer stump
#

You could just put it in DDOL still

#

But yeah, that works

bleak pasture
#

Just to clarify to make sure the context of the discussion is understood: Im going to have a breadcrumb in this format: $"{myFief.parentRegion.name} > {myFief.parentDepartement.name} > {myFief.parentArrondissement.name} > {myFief.ParentCounty.name} > {myFief.ParentBarony.name} > {myFief.name} > {myBuilding.buildingType} > {myBuilding.buildingID}" and each of these parts between the > would be clickable. It's something I'll use in every UI so you can quickly navigate and so far I'd do one scene = one UI so that control would be used all over the game

nimble inlet
#

ngh. I tried this fancy way to assign it but it remains null..

image.png
bleak pasture
#

Kinda ruins my plans if I can't prefab it and simply drop it in multiple scenes

nimble inlet
#

guess 'm gonna have to alter script to just shoot down lmfao. xD

#

wait that wouldn't even help

#

what on earth is going on though. I saw these things shoot bullets for 10 hours straight and suddenly it's null x_x

polar acorn
#

What is null? There's a few things that could be null there

summer stump
nimble inlet
#

the bullets I assume, since they aren't instantiating. I tried switching the script from tracking the player, and something stayed null so, yeah. probably bullets. :/

#

I think I debug logged it about them bullets as well. ah, and I did check that the instantiated objects dont have that reference in the inspector at runtime.

polar acorn
bleak pasture
nimble inlet
#

Imma send the script your way. Idon't think it's the problem though.

bleak pasture
#

They mean that many things could be null it there like bulletPrefab or bulletprefabname. So you should debug that or put a breakpoint and inspect

My Unity projects are often breaking with doing a push from one developer and a pull from another developer's machine. We're using PlasticSCM, but it's still happening.

bleak pasture
#

also where is bullet2 in the editor ?

wintry quarry
bleak pasture
#

Assets/Bullets/Bullet2 ?

nimble inlet
#

I think so.

#

yep

tiny hawk
nimble inlet
tiny hawk
#

And file IDs messing up

nimble inlet
#

that bullet prefab vanishes at instantiate

#

it's assigned to the prefab.

#

looking like this at idle.

#

How do I fix this?

nimble inlet
#

what. suddenly it works. I made no changes.

wintry quarry
#

Make sure anyone making changes is properly checking in all modified files including meta files

tiny hawk
#

Ohh ok

#

Thanks @wintry quarry !

bleak pasture
#

what's wrong with git ? It doesnt work with unity or something ?

#

not a criticism Dudesss, just a subtopic because you remind me of why unity doesn't show me git as possible source control in the edit preferences

summer stump
#

It is the standard

nimble inlet
#

or maybe not. x_x gah

#

had a nice view of screen full of bullets for a video presentation 2 hours ago.

#

basically no changes->they are gone. x_x

wintry quarry
nimble inlet
#

you can see in that image, that they are no longer assigned.

#

two images, first of instantiated objects which no longer have an assigned bulletPrefab

#

and second of one which has it assigned to the prefab of those instantiations at rest.

wintry quarry
nimble inlet
#

that makes sense, but I don't think..

bleak pasture
wintry quarry
#

it's unclear to me if this is a component on a bullet or on a thing that spawns bullets

wintry quarry
nimble inlet
#

this is a component on a thing that spawns bullets.

wintry quarry
nimble inlet
#

yeah.

wintry quarry
#

Ok so show:

  • the script that spawns this thing that spawns bullets
  • the inspector for the thing that spawns the thing that spawns bullets
  • The Bullet Pattern 1 script
  • the inspector for the prefab that is referenced from the first script.
#

Wait you're doing this:
GameObject bulletPrefab = Resources.Load<GameObject>("Bullets/" + bulletPrefabName);

nimble inlet
wintry quarry
#

in other words the variable you have in the inspector is pointless

#

why on earth are you doing this?

bleak pasture
nimble inlet
wintry quarry
wintry quarry
#

just do Instantiate(bulletPrefab)

nimble inlet
#

this is all I have on the spawn that spawns the bullet spawners.

image.png
wintry quarry
#

which prefab is the bullet spawner?

nimble inlet
#

this is what I had in the script before, and now even.

wintry quarry
#

one you got from Resources.Load

nimble inlet
#

this was used before I had resource load.

wintry quarry
#

ok well go back

nimble inlet
#

I can do that yeah.

wintry quarry
nimble inlet
#

the holymines.

wintry quarry
#

Ok click on the holymines prefab

#

show its inspector

nimble inlet
wintry quarry
#

ok great so - now with the resources.load removed, what happens?

nimble inlet
#

the screen would be full of bullets by now if things worked out.

wintry quarry
nimble inlet
#

the uh, holy mines, sir.

wintry quarry
#

which one

#

the prefab?

nimble inlet
#

yeah.

wintry quarry
#

Some instance from the scene?

nimble inlet
#

no, the

#

instantiated

#

objects.

#

yes.

wintry quarry
acoustic arch
#

for jumping with a character controller, for a very simple movement 3D game can i just make it a very fast cooldown instead of checking if it's grounded

wintry quarry
#

because nothing in the code you shared thus far would ever change that

nimble inlet
#

yeah, that's why it's so confusing.

wintry quarry
# nimble inlet yes.

are you 100% sure the exact copy of HolyMines that is referenced from the spawn manager is the one you showed the inspector for?

wintry quarry
nimble inlet
#

yes

wintry quarry
#

That's what you should do to look at it

#

Also is that screenshot from the copy of the SpawnManager that's in the scene? Or elsewhere?

nimble inlet
#

on the scene.

#

neither of the search bars (hierarchy) and assets show anything

#

no compile error after adjusting serialized field

image.png
wintry quarry
#

the only thing I can imagine then is just that we're looking at the wrong instances

polar acorn
#

Okay, so, let's see a screenshot of the entire unity window with the HolyMines prefab selected and the inspector visible

#

(This will make it possible to check several things at once)

nimble inlet
nimble inlet
polar acorn
# nimble inlet

Now, double click on that Bullet2 prefab in the inspector, and show another full screenshot of what comes up

nimble inlet
polar acorn
# nimble inlet

Can you show the code for BulletDamage and BulletCollisionHandler

nimble inlet
#

they can affect this? uh oh.

polar acorn
#

You might be destroying the prefab

#

instead of an instance of it

wintry quarry
#

shouldn't be able to 🤔

bleak pasture
#

this is much better than mystery shows on the discovery channel. Cant wait to know the cause 🙂

wintry quarry
#

If the prefab was destroyed I would expect "Missing (GameObject)" not "None (GameObject)" in the inspector

polar acorn
nimble inlet
#

these are the last scripts I meddled in tbh

wintry quarry
#

loopk fine to me, at least in terms of this problem

polar acorn
# nimble inlet

Okay, right before the Destroy call, add this log:

Debug.Log($"{gameObject.name} has collided with {other.gameObject.name} and is self-destructing", this);
#

Then go through the process that gave you the empty inspector parameter and see if this was ever logged. If it is, show what it prints

nimble inlet
#

this will take a bit

#

that was it.

image.png
polar acorn
# nimble inlet

Okay, those are the clones and they're after the error so it doesn't seem like it's that

nimble inlet
#

but at least the bullets instantiate right?

#

I mean the collision happens...

polar acorn
nimble inlet
#

which script?

polar acorn
#

Let's put in another surgical log:
The line before you instantiate the bullet, the place the error is at, put this:

Debug.Log($"{gameObject.name} is attempting to spawn bullet prefab: {bulletPrefab}", this);
nimble inlet
#

have now gone through all the scripts involved: no duplicates in the assets.

polar acorn
nimble inlet
#

this looks weird to me.

wintry quarry
#

hmm at least one of them works

#

and another doesn;'t

polar acorn
# nimble inlet

Click on the first log, just once. See which object it highlights.
Then click on the second log and see which object it highlights.

#

Are they different objects?

queen adder
#

both my capsule and my camera are at the position 0,0,0.

image.png
#

what is wrong?

polar acorn
queen adder
#

yes

nimble inlet
#

about that, how do see what ithighlights? cause clicking on things generally doesn't show anything to me...

queen adder
#

thank you that was really quick

polar acorn
#

So these logs will show something in the hierarchy when you click on them

#

as long as that object still exists at least

nimble inlet
#

oh rght. it does show the mineclone.

#

I may be detecting some flash of light from those mines. maybe they are destructing.

polar acorn
nimble inlet
#

yes.

polar acorn
# nimble inlet yes.

Can you show the full inspector of that object, during play mode. Even if it has to be multiple screenshots

nimble inlet
#

should I just remove this script from function?

polar acorn
nimble inlet
#

should I still send something?

polar acorn
nimble inlet
#

what, really?

polar acorn
#

Duplicate component

nimble inlet
#

gasdlfkasnlkfdnaslködfa

#

AAAAAAAAAAAAAAAAAAAAAAAAGH

polar acorn
nimble inlet
#

how does that happen, it's there only once in the prefab... x_x

#

the script..

polar acorn
nimble inlet
#

yes.

polar acorn
nimble inlet
#

yes. I do

#

oh no XD

#

aahahahaha

#

I'm dying.

#

thank you I can finish this project in time XD

#

I can get a grade man. XD

I'm trying to destroy tiles in a tilemap by using a tilemap collider 2D and setting the tiles to null based on the hit position as follows:

    {
        if (boxCollider != null)
        {
            Vector3 hitPosition = Vector3.zero;
            foreach (ContactPoint2D hit in collision.contacts)
            {
                hitPosition.x = hit.point.x - 0.01f * hit.normal.x;
                hitPosition.y = hit.point.y - 0.01f * hit.normal.y;
                tileMap.SetTile(tileMap.WorldToCell(hitPosition), null);
            }
        }
    }
    ```
It somewhat works, but the object is for some reason capable of resting on the tiles without destroying them at low velocities
You can see that if I move it again, it continues destroying them
Any idea how I can fix this?
ivory bobcat
#

Maybe your offset is setting the wrong tiles to null

#

Log the to-be nulled tile and see if the point is valid (not null already)
There shouldn't be any reason for a nulled tile to have made a collision.

bleak pasture
# polar acorn Since you asked, ^

🙂 I enjoy trying to learn from the issues other users encounter. It gives me some additional ways to resolve an issue if something similar happens to me

#

Whjen I started to code as an intern Id peruse the technologies my employer was using for a good part of the day (docs/stack overflow/msdn/etc) so I would have a bank of problems/solution in my head of problems I would potentially encounter and some way I could fix it like that

keen crescent
# ivory bobcat Log the to-be nulled tile and see if the point is valid (not null already) There... 
private void OnCollisionEnter2D(Collision2D collision)
    {
        if (boxCollider != null)
        {
            Vector3 hitPosition = Vector3.zero;
            foreach (ContactPoint2D hit in collision.contacts)
            {
                hitPosition.x = hit.point.x - 0.01f * hit.normal.x;
                hitPosition.y = hit.point.y - 0.01f * hit.normal.y;
                //check if the tile at the hit position is null
                if (tileMap.GetTile(tileMap.WorldToCell(hitPosition)) == null)
                {
                    Debug.Log("Tile is null");
                }

                tileMap.SetTile(tileMap.WorldToCell(hitPosition), null);
                
            }
        }
    }

Is this approach for debugging valid? Because I'm definitely getting some debug logs

ivory bobcat
#

That means your hitPosition isn't the expected tile

#

Log the hit position for more info on what you made it set to null

@wintry quarry We're uploading all our changes and there's still missing references. For us in this case, it's our NetworkManager gameobject in our scene that's missing all the references.

is the best way to move the player setting their velocity or is it using addforce

why is this arc too long?cs //Draw upper arc Quaternion tiltRotation = Quaternion.AngleAxis(-scientist.yVisionAngle / 2, scientist.visionPosition.right); Handles.DrawWireArc(scientist.visionPosition.position, tiltRotation * scientist.visionPosition.up, upLeftEndpoint - scientist.visionPosition.position, scientist.xVisionAngle, scientist.visionRadius);

colliders?

wintry quarry

#

i have an unactivate polygon collider to keep my cinemachine camera wigthin boundaries

#

if i activate collision with that would that work?

wintry quarry
#

assuming your character actually moves via physics, it will interact with colliders, yes

Right after pulling my project with free download PlasticSCM, my NetworkManager looks like this. I need to run the scene, stop the scene, run cm update with PlasticSCM, change scenes in the editor, and go back to the original scene, then it gets populated

#

Is there a quicker way to do this?

tender stag
tiny hawk
#

Maybe I'm not supposed to run the scene right from the beginning, and there's another way to build the project

hasty spire
wintry quarry
hasty spire
#

or should i try and edge collider?

#

ok

wintry quarry
#

you could also use 4 box colliders

#

or a single polygon that is in a "picture frame" shape

how do I fix this error?

#

whats the main difference between late update and update?

muted wadi
#

i think late update is run after the frame ends

#

wait no

#

late update is run after Update functions have been called
