[buoyant knot]

does this make sense, prototype?

so transform.up gives up. (-y,x) gives that vector rotated by 90 degrees

(-x, -y) gives it backwards, and (y,-x) gives it rotated by 270 degrees

[final kestrel]

 private void OnCollisionEnter(Collision collision)
 {
     if(collision.gameObject.tag == "Obstacle")
     {
         Destroy(rb);
         Vector3 jumpPosition = new Vector3(transform.localPosition.x + 8f, transform.localPosition.y - 12, transform.localPosition.z);      
         transform.DOLocalJump(jumpPosition, 13, 1, .8f).SetEase(Ease.InSine);
         transform.DORotate(new Vector3(0f, 0f, -90f), 1f, RotateMode.LocalAxisAdd);
     }
 }

Rotate works just fine. But I cannot seem to get the jumping correct. It somehow uses the world transform.

It should jump towards its right but instead it jumps backwards and through the platform.

[heady nimbus]

I appreciate all of this. I do not fully understand, but you've given me some pieces to work with and I'll see what I can do from there. I'm utter garbage at math so that rotation matrix stuff is way over my head, but I think I can figure something out with what you've given

[buoyant knot]

you should learn

[heady nimbus]

Yup, probably.

[buoyant knot]

2 things you should really learn well if you do this sort of physics: 1) law of sines/cosines, 2) basic vector math (like dot products and angles)

rotation matrices are extremely simple. you know how to multiply matrices, right?

[heady nimbus]

I remember vaguely that it was something they tried to teach me in school several decades ago, but not how to actually do it anymore. Lmao

[buoyant knot]

learn again. matrix multiplication is not complicated

this is a 2D rotation matrix. You can calculate the value of each of the 4 cells by plugging in the angle you want to rotate by

when you have that answer, you multiply it by the vector, and that outputs a vector that has been rotated by the angle you plugged in

[heady nimbus]

I appreciate the effort, but this isn't going to click for me right now. I was just doing some unity stuff on my lunch break today, and I've got to get back to real work at this point

[buoyant knot]

for theta = 90 degrees, sin theta = 1, cos theta = 0. So the whole matrix is just
[0 -1, 1 0]

[heady nimbus]

I don't want you to waste too much time or effort putting all this out right now if I don't have time to consume it, but thank you regardless

[dapper lava]

when i have 2D character andi use transform position to move him should i use rigidbody and box colision to not allow him to move throught walls

or is there better option because when i do it the character i lagging in wall

[merry spade]

when you randomly generate obstacles for an endless runner, do you just take random X and Z Values and place it down or what is the strategy with this kind of generation?

[woven crater]

hi, im a beginner, and been worrying about trying to find the best way to do thing. does it matter?

like just trying to make a character move i think there are some like very hidden medthod that i should learn instead of just translate the spite 1 pixel every frame

[dapper lava]

i'm new myself but probably you initiate prefab
Instantiate(somename, position(Vector), Rotation(Quaternion.Euler))
and use random number in y position

[merry spade]

yeah im doing that but i feel dumb generating hundreds of random numbers

[dapper lava]

what

[merry spade]

ok hundreds is too much but 4 or 5 every spawn wave

[rich adder]

depends if you have lanes too

[merry spade]

its getting pretty long because the reference of these objects need to get saved to destroy them if theyre out of reach

[merry spade]

no not like subway surfers no lanes

[heady nimbus]

You shouldn't need a reference to the objects you want to destroy, let the object clean itself up when it's out of range

[dapper lava]

do you reference spawned object and destroy them from somewhere else when they leave screen?

[merry spade]

how can i do this?

[dapper lava]

do you reference spawned object and destroy them from somewhere else when they leave screen?

[heady nimbus]

I was playing around with an "Idle slayer" clone not too long ago, off screen I had a trigger zone that if/when objects reached this zone, they would destroy themselves

[merry spade]

after 3 spawn waves the first one gets deleted right now

[merry spade]

ok so the trigger zone should move with the character

[dapper lava]

and the script deleting the obstacles is in the obstacle

[merry spade]

no i have a generation object that deals with everything

[heady nimbus]

Yea, if that's how you have your world set up.

[merry spade]

when i generate trees and stones how do i know if in the spot i want to generate the tree in is no stone

[heady nimbus]

Clean up zone is just off camera, a set distance

[dawn sparrow]

Is it fine to ask hlsl questions in here?

[dapper lava]

i think so

[dapper lava]

yes

[dawn sparrow]

Gotcha, thanks

So.. i'm confused

SV_ in front of a semantic indicates System Value, which is basically what the system will use to draw the final image,

SV_POSITION grabs the vertex position from the mesh, but why does color get routed with the semantic "COLOR" instead of "SV_COLOR" ??

[buoyant knot]

is there a way to make it so every time a builtin component of type X is added to the scene, i call a certain method?

[rich adder]

https://docs.unity3d.com/ScriptReference/ObjectFactory-componentWasAdded.html
looks promising

[solid verge]

How can i find multiple scripts with findgameobjectswithtag

[solemn fractal]

Hey guys, in my mini game, I need enemies to be spawning all the time non stop. I am using this method and so far working good. cs InvokeRepeating("SpawnEnemy", _spawnAfterXSeconds, _spawnEveryXSeconds); But I need to have more control over it as I need that some enemies spawn only at first 2m and after that other type of enemies will spawn, and even tho in the min 5 i want again the same mobs from the begining to start spawning too, and so on. So i need to have control always when they are going to spawn. and when I determine they will spawn they need to keep spawning until I say stop, they dont just spawn 1 time. Coroutines might not work as they spawn just 1 time right? any tips on that?

[rich adder]

[brittle isle]

My ground detection detects walls

[rich adder]

the same way you said it

var myObjects = GameObject.FindGameObjectsWithTag(c_myTag);

[glossy eagle]

Hi. Does anyone know the reason why in the editor the game works okay but in the build I get a bunch of errors please?

[solid verge]

falling = GameObject.FindGameObjectsWithTag("FallingThing");

[solid verge]

says Assets\Scripts\HealthScript.cs(17,19): error CS0029: Cannot implicitly convert type 'UnityEngine.GameObject[]' to 'FallingThingScript'

[rich adder]

because falling is not an array

[dapper lava]

what will happen if i use normalized twice
new Vector2(1f, 1f).normalized.normalized
will the 0.71 chaange to something like 0.6 to normalize

[solid verge]

what is an array

i did assing it

[rich adder]

https://www.w3schools.com/cs/cs_arrays.php

[solid verge]

FallingThingScript falling; like this

[rich adder]

thats not an array

[rich adder]

depends what the errors are? how can we help with no context

[rich adder]

also this isn't "assigning" this is simply declaring

[nimble inlet]

I'm trying to drag and drop a Text GameObject in UI canvas onto DialogueManager at the top of my hierarchy as a variable. And for some reason, it doesn't allow it. There's probably a really simple reason why but.. xd

[rich adder]

the types dont match or ur trying to add a scene object to a prefab

[solid verge]

string myTag = ("FallingThing"); still declares it as invalid

[summer stump]

I have frequently seen just doing prefab chunks. You "append" a section that you randomly grab. So a section would have hand placed trees rocks etc, and then you just randomly grab a SEQUENCE of those sections.

[glossy eagle]

sorry. For example, in the editor I don't get any errors, but in the build I get a bunch of errors saying that an element from a dictionary doesn't exist. I am trying to change some stuff in the scripts because I'm afraid it could be just that in the editor one thing is being called before the other (and so it works fine), but in the build the order is different idk why

[rich adder]

why and where the hell did you do that

() is not valid string sytntax

[nimble inlet]

hmm. okay. I think it's probably type mismatch then. how would I problemshoot it... I have it declared as follows: "public Text dialogueText;" and that doesn't really leave much to confusion.. and the object is simply created from Create->ui->text.

[rich adder]

you should know why, is your own scripts lol
start by sharing the exact errors messages, use the OnScreen Console asset if you can

[solid verge]

in the place where you put floats and ints

[rich adder]

is your component textMeshpro ?

or just Text

[nimble inlet]

let me see

[rich adder]

what..?

[nimble inlet]

ahh, it's textmeshpro by automation. that's different to text, then?

[rich adder]

indeed

[summer stump]

What does that mean?
Just do this
string myTag = "FallingThing";

[rich adder]

you would need TMP_Text
but also import the namespace its in

[solid verge]

where i put these
public float Health = 100f; public GameObject Player; FallingThingScript falling; public float DamageFromFalling = 25f;

[glossy eagle]

I was using the default unity development build😅 , I didn't know that thing existed

[nimble inlet]

okayyy! nice nice! ty ty

[summer stump]

Variables

[rich adder]

well you seem to be trying to use 1 as a key in a dictionary that doesn't contain it

[solid verge]

still error

[polar acorn]

Show code show error

[glossy eagle]

yeah I can see that. The thing I don't understand is why in the editor works haha. But anyway I'll start debugging

[solid verge]

Assets\Scripts\HealthScript.cs(18,19): error CS0029: Cannot implicitly convert type 'UnityEngine.GameObject[]' to 'FallingThingScript'

[rich adder]

FallingThingScript is not an array and its not GameObject

[solid verge]

yes

[rich adder]

https://assetstore.unity.com/packages/tools/gui/in-game-debug-console-68068
might offer you more insight

[glossy eagle]

okay thank you so much

[rich adder]

yes what?

[solid verge]

it's not a gameobject neither an array

[rich adder]

right thats what the error is telling you

[solid verge]

but i do not know the syntax to when reffering to a script

[polar acorn]

https://docs.unity3d.com/ScriptReference/GameObject.GetComponent.html

You have a list of objects. You need to get components from them

[rich adder]

@solid verge if you want list certain component only skip tags/getcomponent altogether
https://docs.unity3d.com/ScriptReference/Object.FindObjectsOfType.html

[nimble inlet]

ngh. I changed it to textmeshpro+ importing tmpro... but it remains destitute in not allowing the drag and drop :C

[rich adder]

textmeshpro+ ?

can you show ur exact code

[summer stump]

What I wrote would certainly not give an error. So it's either something else or you changed it. You gotta show code for use to help more

Edit: dang lag. Ok, they are handling it with you! Looks good.

[grim stream]

does GetComponentsInChildren<RigidBody2D>() give me an array for rhe rigidbody component of all the GameObjects Children or just one of the children?

[rich adder]

all

including parent

[grim stream]

Including Parent??

[rich adder]

yes if parent has Rigidbody2D it will add it

[slender nymph]

parent as in the object that you called this on. not this object's parent

[grim stream]

okay. Thanks!

[rich adder]

wish there was an overload for skipping parent but hey can't have everything

[solid verge]

wait

am i allowed to make it that big

[rich adder]

https://hatebin.com

[nimble inlet]

yeah, sure. https://hastebin.com/share/efayujarol.csharp

[rich adder]

iirc TextMeshPro is not the GUI version

i said earlier TMP_Text 😛

[nimble inlet]

nooo

[rich adder]

thats the baseclass that covers all possibilities

[solid verge]

https://hatebin.com/sbqujckbzw

like that?

[rich adder]

yup

[grim stream]

Tip: you can do full code blocks with 3 ` symbols so for example:
```cs
(code)
```

[rich adder]

sholdn't for an entire long class tho

[solid verge]

i've done messed up

this is so much pressure

[rich adder]

did you read this part
#💻┃code-beginner message

[solid verge]

i did but i did not understand

[rich adder]

which part

[solid verge]

i guess everything

[rich adder]

ok its very simple

FallingThingScript[] fallingThingScripts = FindObjectsOfType<FallingThingScript>();```

[solid verge]

what doe the [] do

[rich adder]

#💻┃code-beginner message

[solid verge]

array?

[rich adder]

yup

[solid verge]

but how could it.

[grim stream]

It defines it is an array of what is before. so int[] is an int array. someClass[] is an array of the class

[rich adder]

because thats what the syntax is

its very common usually

[solid verge]

and array is a string?

wait

no

[rich adder]

no..

[grim stream]

nope

[rich adder]

array is a type

[grim stream]

an array is a list

[solid verge]

oh

[rich adder]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/collections
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arrays

[solid verge]

can array contain just one thing?

[rich adder]

or none

its a list of stuff

[grim stream]

https://www.w3schools.com/cs/cs_arrays.php

[rich adder]

sent that already

[grim stream]

Microsoft is more correct. But w3Schools is easier to understand 🙂

[rich adder]

they're both correct, microsoft one just has more examples (more array types)

[solid verge]

man i'll just try and solve this tommorow

[rich adder]

but yes its easier to understand

[grim stream]

it can contain multiple things. but all the things has to be ofthe same type

[solid verge]

cause i am way to dumb for this stuff

but i will figure it out

i will try to*

[rich adder]

thats because you're jumping straight into arrays without doing the basics of c# (this is one of them) but you build up to it

[solid verge]

it was all just an attempt to make a health thing

but ok

[rich adder]

exactly..

[solid verge]

i will come back here

[rich adder]

you're trying to do a health thing without knowing the basic c# you're gonna have a harder time

[solid verge]

i mean't that it started by just a simple thing

[rich adder]

knowing the basic syntax/types is invaluable to doing anything

[solid verge]

and another function that if health is less or equal to zero it is done for

with a loop that minuses the health until the health float is less or equal to zero

wait reverse the words cause my internet sent the second one first than the first one

[rich adder]

rip

is it just me or discord is taking a big 💩

[solid verge]

ye

nothing is loading

xd

[fast knot]

Is IEnumerator with yield return new WaitForSeconds(3); a good solution for time based powerups or is there something better?

[grim stream]

is there a function that is called right before switching scene or before the Gameobject is destroyed?

[dapper lava]

what type is Time.deltatime

[grim stream]

Float

[eager elm]

it works if you don't plan on adding pausing or saving

[eager elm]

OnDestroy()

[fast knot]

Oh, pausing is a good point. So the Coroutine would still run if i pause the scence?

[eager elm]

ye, to work with pausing you would need a while loop that checks every frame if the game is paused

[summer stump]

@solid verge One big issue I see is here
FallingThing = FallingThing.GetComponent<FallingThingScript>();

You apparantly have a FallingThing Gameobject reference, and you want to use that to get a reference to the FallingThingScript.

You could just change that variable to FallingThingScript and drag the object into there, then delete the line I copied above

[fast knot]

Thank you! I will have a look on this

[summer stump]

Me too. Dang

[rich adder]

ah yeah discord just died there for a bit lol

[solemn fractal]

Is there a way to have control over spawning with coroutine or InvokeRepeating. Like i say start spawning now until i say keep spawning and stop when i want and come back spawning again.. ? Or should i use a mix or other ways?

[rich adder]

store Coroutine in a variable

you need a while loop inside coroutine for Repeating behavior

[solemn fractal]

hmm ok

like that? cs myCoroutine = StartCoroutine(MyCoroutineMethod());

and stop like that cs StopCoroutine(myCoroutine); ??

[rich adder]

yup

[solemn fractal]

and inside i would use a while ?

hmm ok thank you

[rich adder]

eg

while(true){
//Spawn
yield return new WaitForSeconds(seconds);
}```

[solemn fractal]

Got it, thank you

[true pasture]

having a dumbo moment. what is the proper way to see if a button is being held in new input system. Cant find it online somehow. is it context.started?

[solemn fractal]

Also another question, is there a feature in unity to put a watch in the screen couting down the time? like 15minutes counting down to zero? Or it need to be done 100% hardcoded?

[eternal needle]

You can stop a coroutine yes. you can just have some bool keep track if you should be spawning at this moment and change the bool based on your logic. Then you can do your work in update instead of starting and stopping coroutines if you wanted

[fast knot]

Is the "Invoke" timer running while a scence is paused?

[true pasture]

like theres this but I don't understand how those are related to hold inputs.

[fast knot]

check out .started and .canceled

[nimble inlet]

okay, this works again. xd so I was trying to search data on that tmp_text workings, but all indicators tell me to use something else, like something specific to canvasUI texts. But then referring to those I get a type mismatch. I also tried the TMP somewhere, but it didn't work.

(alhtough I maybe did it poorly. google nor gpt was helpful finding that. the unity forums are down/infinitely refresh too)

[strange shale]

so... trying to make a simple double jump... (I was using add force, but I guess I need to do something else first...)

I'm trying to make the midair jump ignore the character's current Y velocity and always make the midair jump uses the same up speed

[short hazel]

On the new input system "holding" is not the same thing as in the legacy input manager. Basically in the new input system holding would refer to a button with a Hold processor on it. That's what performed is talking about here

[slender nymph]

reset Y velocity to 0 immediately before applying force for a jump

[strange shale]

do I just type reset Y and done?

[short hazel]

You'd start holding, started gets invoked. Keep holding until the specified duration, and performed is invoked. Release the button anytime, and canceled is invoked.

[rich adder]

can you show which component you're trying to drag in the field ? and the screenshot for entire object inspector @nimble inlet

[short hazel]

So if your hold is about "tell me when I start pressing down, and stop pressing down", then you want the started and canceled events

[true pasture]

how do you reset only the y velocity? it wont let me do rigidbody.velocity.y = 0 (I also was trying to do jumps)

[nimble inlet]

okay, a second.

[slender nymph]

https://unity.huh.how/compiler-errors/cs1612

[nimble inlet]

what the f- is an object inspector. that's an object. it's the inspector. XD

[rich adder]

you not know what inspector is in unity I suggest you start from the basics 😛

[true pasture]

the inspector window. thats the hierarchy that you posted

[nimble inlet]

there's also inspefctor window. multi image.

[polar acorn]

It's not the inspector

[nimble inlet]

hu?

[polar acorn]

Show the object's inspector

Not the hierarchy window

[rich adder]

idk discord is lagging i only see 1 image

[nimble inlet]

it sure is

there's 3

[true pasture]

you have to click on the image and press over,

they did post the inspector

[grim stream]

is there an attribute to hide a public field in the editor/inspector?

[slender nymph]

HideInInspector
it will still be serialized though

[rich adder]

Oh..there's no thumbnails but you can click through it

[wintry quarry]

Sure [NonSerialized] or [HideInInspector] depending on what you actually want to do

But - probably best not to use a public field in the first place if that's what you want

[polar acorn]

Huh, weird. Discord not doing too great today it seems

[slender nymph]

probably due to discord currently exploding. about 50% of my messages are even getting through right now because of it

[rich adder]

what about the object you're trying it into

[nimble inlet]

let's see..

[rich adder]

yeah discord is dying rn

[grim stream]

Its just for aestetic purposes. Variables that should not be set by human but still need to be accesed by other classes

[polar acorn]

That's looking for Text, your object is a TMP_Text

[rich adder]

its still Text

[nimble inlet]

okay how is that possible. :C it's literally defined as "TextMeshProUGUI" atm...

[polar acorn]

Did you save

[rich adder]

did you save

[grim stream]

TMP_Text is TextMeshProUGUI right?

[nimble inlet]

100%

[rich adder]

its the baseclass so yes

[polar acorn]

Do you have any compile errors?

[rich adder]

TMP_Text is better imo cause its shorter to type

and covers more components

[nimble inlet]

there's some new ones...

[polar acorn]

If you have any compile errors, fix them

[nimble inlet]

the compile errors make no sense. But these weren't here before I think, when things still didn't work.

I think it's saying I have a duplicate script of the same name...

[polar acorn]

Then you should probably listen to it

[nimble inlet]

yep. I don't know when that got created. xd I deleted one and there's tons of errors now from that. good stuff :C

[true pasture]

so I should add a holding interaction on my jump action. How do I access that in code (does the processor turn that into a held action automatically?). For example I want my character to rise with addforce while its being held then when let go the addforce stops.

[strange shale]

alright... got it

[short hazel]

Then you don't want the processor. See #💻┃code-beginner message

[short hazel]

The Hold processor converts the button into a "raise no performed event until the button has been held down for X seconds"

[true pasture]

so why would I need to add cancelled

[short hazel]

To know when to stop adding force

[scarlet skiff]

can u make a parent inside a parent?

[true pasture]

but how does that work with the if statement?

[nimble inlet]

okay. there's only one error left and that's the type or namespace "image" is not found. code being " public Image textboxImage; in the previously sent code.

[polar acorn]

Is it image or Image

[nimble inlet]

Image

[scarlet skiff]

bruh like a parent, in the hierarchy section

[true pasture]

if context.started (addforce)

then what triggers the context.cancel (is it just if context.cancelled) empty block

[polar acorn]

Do you have the UI namespace?

[nimble inlet]

no. added it. good thinking.

[polar acorn]

Any object can be a parent object of another, even if it already has parents

[nimble inlet]

wow unity is so friendly. xd new errors only hiding behind old errors.

[short hazel]

It doesn't. Here it'll only add force once, when you start pressing the button. Take what's in the if statement out and store it for later. Set a bool to true in that if statement. Add another if statement for canceled in which you set the bool to false.
Then paste your code in FixedUpdate, and only apply force if the bool is true

[scarlet skiff]

ty

[nimble inlet]

I have managed to remove all the errors in compiler+vscode... I cannot still drag and drop the object onto that script.

[short hazel]

Select (do NOT double-click) the script in Unity, in your project files. It should show its contents in the Inspector. Make sure it's identical to what you can see in your code editor

[rich adder]

alr show new inspector of the Entire object, not just that component

[nimble inlet]

should be identical

[polar acorn]

Is it

[short hazel]

Ensure that it's the case

[polar acorn]

How about send a screenshot of your full unity window with:

1. This object visible
2. The console tab open and visible

[true pasture]

something like this?

[nimble inlet]

which object do you prefer to see in the inspector for this?

[polar acorn]

The one with the script that you can't drag anything into

[nimble inlet]

behold my beautiful game

[short hazel]

Warnings!

Read them

[nimble inlet]

they don't matter no?

[short hazel]

The one in the Inspector does

[polar acorn]

There is no script here

This is an empty script

[rich adder]

🫠

[nimble inlet]

oh snap, it got removed when I removed the duplicat.e

[short hazel]

Yep, if you also want it to stop when you hold for more than 1 second

[true pasture]

yeah

[nimble inlet]

it WORKS!!

thank yuuu!

[solemn fractal]

hey guys doing some coroutine tests, but it seems I cant do like that. any ideas?

[rich adder]

||switch IEnumerator to Coroutine|| 🥣

[polar acorn]

What are the errors

[slender nymph]

https://unity.huh.how/coroutines/stopcoroutine

[solemn fractal]

that fixed first

but on stopcoroutine still got the error

[polar acorn]

The first error says you cannot assign a Coroutine to a variable of type IEnumerator.
The second says you can't call StopCoroutine on an IEnumerator.

[rich adder]

StopCorotuine(coroutineVar)

[solemn fractal]

omg

yes

i am so dumb.. 21h haha thank you !!

worked

[rich adder]

the errors tell you exactly whats wrong usually xD

[solemn fractal]

I did a reserach and said I had to use private Ienumerator myCoroutine;

[solemn fractal]

for me as NB not always is that obvious 😛

[rich adder]

true, when in doubt always look at the API/return type of the function

[solemn fractal]

Thank you

[rich adder]

StopCoroutine has 3 types as params btw

Coroutine is the return here

for stop you can pass IEnum but you already stored as Coroutine

[solemn fractal]

oh wow

interesting..

For now I will stick to the simple method as I am starting, but already took not of those to check it out later. thank you a lot

Another question, to create a count down timer like 15m showing on the screen 15:00 until it gets 00:00. need to be hardcoded or there is a feature on unity for that?

[rich adder]

you need to make that timer yourself

[solemn fractal]

ok thank you

[rich adder]

update the UI text

[solemn fractal]

with time.time or something like that?

[scarlet skiff]

ok hear me out
i have 2 scripts

A: For the boulder, which tells it how it can move n whatnot, boulder is now a prefab as well
B: boulder spawner, if u press space it will run a method in script B that spawns a boulder

however i am having a bit of trouble with this, im not quit sure how to build the spawner method

Currently, i just have

no Update or another Coroutine just for timer

what you can do is put it in the same while loop if you want if its related to that previous coroutine

[slender nymph]

you should not be calling the constructor for a MonoBehaviour

[solemn fractal]

hmm ok, will check it out doing a research on it. thank you

[slender nymph]

or use Instantiate to spawn an instance of the prefab that is referenced by your component

[scarlet skiff]

oh ye Instantiate

used to working with monogame

[fierce shuttle]

For a timer, I often use a variable of seconds representing the total time I want (for example 60 * 5 would give 300 seconds), then you can tick those seconds down with navarone's suggestions, and display those seconds as detailed as youd like to some text object (days, hours, minutes, seconds, milliseconds, etc) - though for this approach, you may need to do some math on the seconds and possibly ToString formatting, as the math will result in decimals more often than not

[solemn fractal]

Got it, thank you very much !

[scarlet skiff]

same name..

[polar acorn]

What is Catapult_boulder

[summer stump]

It takes a variable, not the string name of a prefab
You have no variable named Catapult_boulder

[gray crest]

Im using object pooling of two different objects, when the game starts the its objects pools 8 of the first object and when i press a button it then switches to objects pooling the second item, but the transition of making the 2nd active and 1st inactive causes lag spikes on android. There are some scripts on the objects but when i check the profiler there is no certain script thats causing the lag drop, what can i do here?

[buoyant knot]

i think you need to check profiler to see what the program IS doing during the lag spike

if the cost is being distributed very evenly, check for things that shoukd only be called once to see if they are called multiple times

[eternal needle]

how many objects are you pooling in the 2nd pool? this sounds weird to me, that you are making a pool inactive and making another active. An object pool is just a place for inactive objects to live

[gray crest]

its one objects pool but at the start i only make active the first one, then when a button is pressed, hide the 1st and show the second. its all the scripts on the second object starting all at once, what can i do to make this transition smoother?

[eternal needle]

what you are describing (and the screenshot) makes me think this isnt actually an object pool. Is this Tile_Forest and Magic Forest thing your scene objects? What are they

[gray crest]

they are both objects for my background in the second screen shot, when i press a ui button they switch. I can link the code where i object pool them

[eternal needle]

Yes show your code, i am very convinced right now that this isnt actually an object pool

This sounds more like additive scene loading, but with prefabs

Make a variable and drag in the prefab
public GameObject boulder;

[gray crest]

sorry its a lot of code but its really just the first 3 mehtods

[eternal needle]

honestly i got no idea what part im supposed to be looking at, but u can profile certain sections with this
https://docs.unity3d.com/ScriptReference/Profiling.Profiler.BeginSample.html

[scarlet skiff]

can you elaborate on

Make a variable and drag in the prefab

Drag in... where?

[summer stump]

The inspector
If you have a public variable. There will be a box in the inspector. Drag it into there

See the boxes in the left image here
#💻┃code-beginner message

It will be like that (but yours won't be an array or list or whatever they have)

[gray crest]

yeah i get it but this is the object pool

    private void Awake()
{
        coinSpawner = FindObjectOfType<CoinSpawner>();
        objectPool = new List<GameObject>();

        // Fill the object pool with all objects from the prefabs list
        foreach (var prefab in prefabs)
        {
            for (int i = 0; i < maxObjects; i++)
            {
                obj = Instantiate(prefab, new Vector3(currentX, 57.41f, 25.19f), Quaternion.Euler(0f, 180f, 0f));
                objectPool.Add(obj);
                obj.SetActive(true);

                // Activate only the object at index 0
                if (prefab == prefabs[0])
                {
                    activeObject = obj;
                    currentX += spawnOffset;
                    obj.SetActive(true);
                }
            }
        }

        // Find all SpawnerScript instances and add them to the list
        SpawnerScript[] foundSpawners = FindObjectsOfType<SpawnerScript>();
        spawners.AddRange(foundSpawners);
}

[eternal needle]

this still looks more like additive scene loading but using prefabs, instead of an actual object pool.
Also for some reason you've now changed it to set every object to true on awake, while in the hastebin it was obj.SetActive(false);

[gray crest]

yeah im testing different ideas

[eternal needle]

If these prefabs are massive, then yea its gonna take time to set them active/inactive. Your solution in that case is to make them smaller

can you show the hierarchy of this prefab

[gray crest]

i sec, yeah its pretty busy but idn what to reduce

[scarlet skiff]

btw this is for rotation, right?

if so whats W for

[eternal needle]

You can either go through the giant prefab and load objects over time instead of trying to do it all at once
break them up into smaller prefabs then load them slowly
use additive scenes instead with the same concepts above

[summer stump]

Quaternions represent a rotation. You really don't need to know what W means. But if you want you can look up the incredibly complex math of quaternions.

In game dev you should just work with euler angles though. The x y and z will NOT be what you see in the inspector

[sage mirage]

Hey, guys! I have a question. Can I pause and unpause my game on IEnumerator? On my game, I have made pause menu screen to be enabled and disabled with a time delay. That's why I made everything on IEnumerator. So, I want to freeze the game and unfreeze after unpausing. Can I do something like that insdie IEnumerator?

Check my code

{
    if (Input.GetKeyDown(KeyCode.Escape) && pauseIsActive == false)
    {
        yield return new WaitForSeconds(pauseDelay);
        pauseIsActive = true;
        pauseMenuScreen.SetActive(true);
        Time.timeScale = 0;
        Debug.Log("Pause menu screen is active!");
    }


    else if (Input.GetKeyDown(KeyCode.Escape) && pauseIsActive == true)
    {
        yield return new WaitForSeconds(pauseDelay);
        pauseIsActive = false;
        pauseMenuScreen.SetActive(false);
        Time.timeScale = 1;
        Debug.Log("Pause menu screen is not active!");
    }
}```

[gray crest]

its seems like alot but i only have 2 scripts and everything is low poly, every material is using shared instanced

[rich adder]

bad

[sage mirage]

I have a problem with Time.timescale

[slender nymph]

https://docs.unity3d.com/ScriptReference/WaitForSeconds-ctor.html

Suspends the coroutine execution for the given amount of seconds using scaled time.

[rich adder]

why do you have Inputs/keycode inside this function

[slender nymph]

yeah also shouldn't be getting input in there

[wintry quarry]

you would use WaitForSecondsRealtime if you want to wait for realtime to pass while the time scale is 0

[eternal needle]

🤷‍♂️ then start profiling which section of your code is specifically bad. If you're convinced its not the prefab loading, then what

[sage mirage]

I thought, I could use input inside it and write StartCorountine on Update() that's what I did

Anyway, I will fix it

[rich adder]

you're like starting a coroutine each frame,

[sage mirage]

Oh, true!

[scarlet skiff]

how come?

[wintry quarry]

As it says GameObject doesn't have a FireProjectile function on it

so you can't call FireProjectile on a GameObject reference

you're also trying to call it on a prefab which is sus

[scarlet skiff]

but i put the perfab in the gameObject field

dragged it into it

[wintry quarry]

So what? GameObject still doesn't have such a function

[rich adder]

bool isGamePaused = false;
    Coroutine pauseRoutine = null;
    void Update()
    {
        if(Input.GetKeyDown(KeyCode.Escape))
        {
            if (pauseRoutine != null) return;
            pauseRoutine = StartCoroutine(PauseGame());
        }
    }
    IEnumerator PauseGame()
    {
        isGamePaused = !isGamePaused;
        if (isGamePaused)
        {
            //dostuff paused
        }
        else
        {
            //dostuff not paused
        }
        yield return new WaitForSecondsRealtime(wahetevr);

        pauseRoutine = null;
    }```

[scarlet skiff]

the prefab had a script which had it

[slender nymph]

you should do some basic c# courses to learn how types work

[ivory bobcat]

Well, you're referring to it as a Game Object only

[wintry quarry]

you can never call FireProjectile on a GameObject reference. If it's from some script of yours you should be using that script type, not GameObject

[ivory bobcat]

Refer to it as the specific script, if needed.

[scarlet skiff]

i tried typing out the name of the script

but it makes it green, so it refers to the class

[wintry quarry]

That's what you want...

GameObject is a class too you know

[ivory bobcat]

public SpecificScript ss;```

[scarlet skiff]

or no it says this

[scarlet skiff]

yea thats what i did but then i got confused

[wintry quarry]

you're using the class name there when you should be using the field name

notice how you did myBoulder.FireProjectile()

not GameObject.FireProjectile()

[ivory bobcat]

Maybe lookup some basic C# tutorials

[wintry quarry]

you're confusing the type of a field with the field itself.

[rich adder]

another good reason class name should be Capitalized so you know its a class and not the field/reference

[scarlet skiff]

bruh i was afraid to change class name cuz the class name has ot match the script name n i didnt wanna change naything

otherwsie id have capitalized class names

[rich adder]

if you rename the class in VS iirc it also renames the file

ctrl + r twice tho

[scarlet skiff]

i see

[polar acorn]

So change both

[rich adder]

see it says Rename symbol's file

not sure why its called symbol but wahetv lol

[scarlet skiff]

how did u get this little menu

[polar acorn]

A Symbol is what the name of a thing is called. int x = 3, x is the symbol that represents the variable

[rich adder]

oh damm I feel silly not knowing thats the name

xD

[polar acorn]

Variables, properties, classes, methods, and structs all have "Symbols", so you can use that when you don't know or care which one you're talking about

[rich adder]

click on the thing and do ctrl + R twice

ir right click + rename

[rich adder]

ohhh nice TIL

[scarlet skiff]

box was already ticked

[polar acorn]

So then when you rename the class it'll rename the class's file

[rich adder]

yup that means it should rename the file too

[scarlet skiff]

when is it suppsoed to change the files names?

the symbols name, i mean

[summer stump]

When you hit enter
It is immediate

[timber urchin]

https://hastebin.com/share/nalanakobu.csharp

[rich adder]

thats weird isn't raycast hit a struct

[slender nymph]

just use else for that second block instead of checking if hit.collider is null

[timber urchin]

Im getting the following error, I know it is probably simple to fix but for the life of me I cant seem to fix this

[polar acorn]

When you are done typing

[summer stump]

You use hit in another method (WallDestroy)
Hit is declared locally though

[slender nymph]

structs are only assigned their default values automatically when declared as fields. local variables can still be unassigned

[polar acorn]

if (hit.collider == null)
What is this checking if the raycast hits nothing

[scarlet skiff]

and uhmm is there a chance or something that could contribute to it not working?

[polar acorn]

hit doesn't exist

[rich adder]

Ahh I see

[polar acorn]

What doesn't work

[scarlet skiff]

if it DOESNT change the symbols name

after enter

also i clicked on something n it looks like this now

[summer stump]

Rename it back to the same thing it was before. Then rename it again

[scarlet skiff]

the boxes r gone 😔

[scarlet skiff]

worked 👍 '

[rich adder]

you can also do new() I think

that would still make no sense though cause nothing is assigned to it

[slender nymph]

not even necessary though. they can just use else instead of that second if statement. since checking if hit.collider == null is the same as checking that the raycast didn't hit anything

[rich adder]

yea makes sense

[slender nymph]

but yeah assigning either default or new() would technically solve their error

[summer stump]

The issue is using it in WallDestroy without it being a class variable. That's where line 34 is

But yeah, else would make more sense there

[rich adder]

is this rayhit even supposed to be local?

[summer stump]

No, definitely not

[scarlet skiff]

yall am i a game dev? 🙏

[wintry quarry]

technically

[scarlet skiff]

im making it out the hood

[rich adder]

not if you forget to save when its * on filename
after that transformation is complete

[slender nymph]

ah yeah, my bad got the lines mixed up (though the issue i was pointed out is basically the same). they should just be calling Walldestroy from their objectfind method instead of from update. then they can pass the raycast hit when the raycast is successful

[polar acorn]

Why do you have boulder and myBoulder? Wouldn't it make more sense to just spawn boulder?

[rich adder]

yeah that GameObject is useless here

[timber urchin]

Yeah this makes sense now idk why I didn't think of that, also changed the null to else instead

[scarlet skiff]

hmm true

[scarlet skiff]

or wait

[rich adder]

also you would change GameObject to Boulder in the instantiate

[scarlet skiff]

dont i need it to be GameObject to Instantiate

ohhgh yee yee

what happens if i replace Boulder spawnedObject with boulder

[polar acorn]

You'd store the result of Instantiate in your variable boulder

[slender nymph]

yeah ideally you'd have a second variable of that type (probably one that is not public) that holds the reference to the instantiated object. assuming you'd want to be able to instantiate a boulder more than once with this class

[scarlet skiff]

hmm i think i get it

its like taking the balue print and making an object out of it and assigning it to a variable, if i assign it to the blue print then the blue print is gone and i just have one instance?

[timber urchin]

I thought I got what you meant but apparently not, would you be able to show me what you mean by this?

[slender nymph]

do you know how to pass an object as a parameter to a method?

[timber urchin]

I think so yea

[slender nymph]

so then what part of what i suggested are you not understanding?

[scarlet skiff]

soo.. i dont really get this

i want rockSpawner to be a part of the catapult_1 parent

[true pasture]

can I not access this value onEnable? its giving object ref error

[summer stump]

Double click the prefab to unpack it
Modify it there

[slender nymph]

SMM.instance is probably being assigned to in Awake. don't access its value until Start

[wintry quarry]

Most likely this is running before instance is assigned.

[timber urchin]

Okay actually I misread your message how would I do this?

[true pasture]

ah i see TY

[scarlet skiff]

hmm i think its best if i just delete the boulder, then in the script have a way to spawn in the first boulder

[slender nymph]

if you do not know how to pass objects as parameters there are beginner c# courses pinned in this channel to help you start learning how to use the language

[scarlet skiff]

however, evenm if i wanna move rockSpawner to that parent it still gives same error, even tho it is not a prefab

[rich adder]

right click the prefab and click Unpack

then you can modify it

[summer stump]

Catpult_1 is a prefab..

[scarlet skiff]

hmm hmm

[rich adder]

Catpult_1 is a model/fbx
Catpult_Stone_1 is prefab

unity treats model files as prefabs its weird

[summer stump]

Oh yeah, you right. Just saw a big of blue and ran with it haha

[rich adder]

yeah lol they should've really made it a diff color

[timber urchin]

Thanks, I did this stuff years ago but I've almost entirely forgot alot of important stuff so I'll definitely need a recap of basics

[scarlet skiff]

ok so i unpacked the prefab, added the rock spawner, then made it a prefab again, but the movement script doesnt make the rockSpawner follow

[rich adder]

wdym the movement script?

btw always keep ur console window docked somewhere where its fully shown

[scarlet skiff]

the parent has this script

[polar acorn]

Don't use new Rigidbody

Don't create any unity components with new

[rich adder]

is Moving Forward printing

[slender nymph]

stop newing components

#💻┃code-beginner message

what you really want there is just a reference to the Rigidbody by dragging it in the inspector

[rich adder]

^this also swap from translate to rigidbody based movement

[scarlet skiff]

cleaned up the script i didnt need the rest

[slender nymph]

just so you know, your movement does not respect colliders

so the object will not collide with anything

[scarlet skiff]

wait nvm i do need hte rigbibody so i can use rigidbody based movement

[viral hemlock]

quick question how can I spawn the same object at 2 points

[rich adder]

duplicate the line & change pos on second?

[slender nymph]

call Instantiate twice where you provide one of the relevant points each time

[polar acorn]

Spawn it in one place, then spawn it again at a different one

[viral hemlock]

my bad i also want the two points to be used randomly if that makes sense?

[slender nymph]

you're gonna need to elaborate because that can be interpreted in a number of ways

[polar acorn]

Spawn it in one random place, then spawn it again at a different random one

[austere monolith]

who is the best youtuber for tuts

in opinions

[viral hemlock]

for example if I had point 1 and point 2 I would want them to be used randomly

[scarlet skiff]

aight less go gang

[rich adder]

   public Transform[] spawns;
   private int spawnAmount = 2;
    void Spawn()
    {
        for (int i = 0; i < spawnAmount ; i++)
        {
            var instantiate = Instantiate(obj, spawns[Random.Range(0, spawns.Length)], Quaternion.identity);
        }
    }```

[austere monolith]

whats the best way to learn?

[rich adder]

practice / lots of repetition

[slender nymph]

you should also not be applying physics like AddForce inside of update, do that in FixedUpdate. also when you make that change remove the deltaTime multiplication. and you'll likely want to use ForceMode.Impulse rather than the default forcemode

[slender nymph]

[scarlet skiff]

do i keep the rotation in fixedUpdate too?

nope, rotation is too slow then

but then.. should i just buff the speed or put it in Update? 🤔

i have a feeling that Update has to be blue

[rich adder]

rotation you want rb.MoveRotation

also nesting Update inside FixedUpdate is wrong

Update never gets called there

Vector3.forward should be transform.forward

[scarlet skiff]

dam i didnt even notcie i did that

[scarlet skiff]

makes sense

i did think about it

that it had to be based on rb

[rich adder]

you technically can still use transform.rotate but the inaccuracy might be significant enough

[scarlet skiff]

well when it stopped working after a few changes so

[rich adder]

you should probably show updated code

also don't use screenshots

what does the last arguemtn for Quaternion do tho, i understand the first 3 are the rotation around the 3 axis

[scarlet skiff]

ye but the code isnt long enough for it yet, i think so at least

[rich adder]

wdym Quaternion has 4 values (x,y,z,w)

[scarlet skiff]

like myRigidody.MoveRotation(new Quaternion(rotationSpeed,0 ,0 ,0));

[rich adder]

you should never have to use new Quaternion

like ever

work with Euler angles

[scarlet skiff]

it is asking for Quaternion

[summer stump]

The first param is the x value, so it would make no sense to put rotation speed there

[summer stump]

Quaternion.Euler()

Or whatever it is

[rich adder]

yup that one

[scarlet skiff]

well i mean it did work before

[summer stump]

?? Doubtful

[scarlet skiff]

its not rly rotaiton speed, but how much it should rotate with

maybe my naming is bad

[rich adder]

quaternion value don't go above 1

so it would never work

[summer stump]

Each value of a quaternion is the TWIST around an axis. I guarantee it is not what you think it is

[scarlet skiff]

oh i had 0.05 - 0.4

[scarlet skiff]

i... did think right 😢

[rich adder]

The reason it worked before is because transform.Rotate can take in a Vector3 as arguement, if you want to use eulers

it has different signatures

moverotation doesn't have Euler (only accepts Quaternion)

[summer stump]

Did you think it would match what is in the inspector for rotation?

[scarlet skiff]

uhhh wdym by inspector for rotation

[summer stump]

Do you know what the inspector is?

Which part is throwing you?

[scarlet skiff]

not exactly

[summer stump]

It's the window on the right be default, with the word inspector above it. It has all the values of a game object. Like position and rotation right at the top.
I recommend taking the Unity Essentials path at learn.unity.com before proceding further

[rich adder]

this would be example of euler

same rotation in quaterion

[scarlet skiff]

oooo

its called inspector

i just call it right side

[wintry quarry]

but you can move it to the left side!

[rich adder]

and/or have many popups of them!

[scarlet skiff]

ah... damn bro..

shoulda peeped game n locked in in class

[modest dust]

Or you can turn it into oblivion and not have any inspector tab at all

Who needs it anyways

[rich adder]

make custom inspector, win

[modest dust]

Or just make your own game engine

[rich adder]

I want my fields to have analog guages

[scarlet skiff]

bro i just wanted to make a catapult shoot boulders

i am not making it outta hood

[rich adder]

you still aint share the new modified script

[scarlet skiff]

cuz it had an error

which i was trying to look up

but the explanation to it dont really sit with me

[rich adder]

why are you using new

[modest dust]

Quaternion.Euler returns a Quaternion

[rich adder]

and are u sure X is what you want to rotate instead of Y

[modest dust]

It's not a constructor, it's a static method, no need for new

[scarlet skiff]

uh... yea..

..?

[rich adder]

X would try to tilt it up and down

like a airplane

[scarlet skiff]

since when

😭

[slender nymph]

always. because it rotates around that axis

[scarlet skiff]

dam

i see

thats...

uh.. okey

[static cedar]

Where the pic of yaw, something?

🍵

[scarlet skiff]

yaw?

[rich adder]

Y rotation in unity is yaw

[slender nymph]

this should also be helpful where head is the yaw in this image

[rich adder]

i dig it

[scarlet skiff]

i c

this is in degrees, right?

[slender nymph]

yes. though you won't be correctly accumulating your rotation there if you're using MoveRotation

unless this is in FixedUpdate where it won't really matter if you accumulate it or not

[wintry quarry]

it should be * Time.fixedDeltaTime if in FixedUpdate to be degrees per second, and is just incorrect if in Update

[scarlet skiff]

maaaann..

cant even say bro

anyways, it no longer knows where forward is

its movement is no longer based on the rotation

and its 12:14

i have yet to do things

that i needa do

😔
this has been a lil humbling and wee bit disapointing

[rich adder]

bro speaking in riddles

[polar acorn]

Because you should probably try to say something actually useful

[timber urchin]

Think I have got it, tried to remember on my own took a bit but think I got it its not throwing any errors although correct me if I am wrong here

[rich adder]

did someone give you the impression gamedev is easy ?

[scarlet skiff]

teacher said that we technically should only need 15 minutes... i spent like 6h+ now... and didnt even complete 50%

how is this is even possible 😭

[rich adder]

15 minutes to what exactly ? whats the assignment..

[scarlet skiff]

its just an exercise, we just gotta make a catapult shoots balls

and add more stuff if we have time

[rich adder]

no sane teacher would say any gamedev would neeed only 15 min

its possible but why, would you

[viral hemlock]

this is a stupid question but is there an opposite of the random class

[frosty hound]

Sounds more like a 15 minute assignment after a whole class/classes and someone slacked off.

[slender nymph]

now the next thing i recommend changing is perhaps to not rely on the object's name but rather a tag or even a specific component. Then if you instantiate a clone of the Wall object that clone will also be affected without you needing to make sure you rename it

[polar acorn]

🤨

[rich adder]

quite possible xD

[scarlet skiff]

idk teach lowkey chill

[timber urchin]

Ah yea true

[slender nymph]

wtf would be the opposite of that?

[scarlet skiff]

yea ngl i cannot focus to save my life

[rich adder]

opposite of random class? whats that even mean

[scarlet skiff]

i did learn... some things..

[frosty hound]

Well then, to answer your question: it is possible.

[scarlet skiff]

i dont think anyone managed in 15min

[frosty hound]

Using AddForce to launch a rigidbody is only a few lines of code. It really is the basics of Unity.

[scarlet skiff]

but most of em were almost finished after like 2 - 2.5h

[rich adder]

yeah but they're doing like rotating a catapult and all that

[frosty hound]

https://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html

[rich adder]

not sure if thats part of the assigment or what

[slender nymph]

what are you trying to do here

[polar acorn]

Random is not a function

[timber urchin]

Just realised I get this upon play

[scarlet skiff]

i think u need random,randint

[viral hemlock]

i dont what random data

but what class would i use

[wintry quarry]

then why are you doing anything with a class called Random?

[rich adder]

pass specific values?

[wintry quarry]

what do you want?

[slender nymph]

oh right, you should only be calling your Walldestroy method if you actually hit something with the raycast and pass in its raycasthit, not just a new one

[slender nymph]

for what?

[polar acorn]

Then don't use random...?

[timber urchin]

Ahh got you

[rich adder]

thats like saying I want to cross the street but not blindfolded

[viral hemlock]

alright what function or class could I use to use fixed data

[polar acorn]

If you don't wnat random... don't use random

use the value you want

[scarlet skiff]

here is what i meant earlier by it no longer knowing hwere forward is

[polar acorn]

the... the data you want

[slender nymph]

what do you mean? just use the data

[polar acorn]

use that

[rich adder]

maybe static data like ScriptableObject

[slender nymph]

please share your !code correctly. nobody wants to scrub through a video to try to decipher what you are doing

[rich adder]

#💻┃code-beginner message

fix ^^

[scarlet skiff]

i see

[slender nymph]

just use AddRelativeForce or that fix

[timber urchin]

So that should be inside the if statement here like this yeah?

[scarlet skiff]

wait i already did this

[rich adder]

you read the wrong thing

[scarlet skiff]

wait

i see

[wintry quarry]

why are you calling it with a new RaycastHit()?

[slender nymph]

now use the already populated hit variable rather than constructing a new RaycastHit

[timber urchin]

Meant to change that oops

[summer stump]

The number 1. It is known and doesn't change. So kinda the opposite of random?

[viral hemlock]

alright guys sorry for the difficulties i figured it out

[timber urchin]

Alrighty thanks

[rich adder]

the vector3.forward is World dir
transform.forward is local dir

or what Boxfriend said instead

[scarlet skiff]

👍

[timber urchin]

Thanks man thats it working, appreciate the help!

[scarlet skiff]

dam why it slides so much

dam there is so much wrong still

makes sense now how game devs be staying up til 3

what did i get myself into...

anyways ill have to hit the hay now, thanks everyone for your pateince today

[slender nymph]

ah was the AddForce supposed to move the catapult rather than launch the boulder? because if so you should remove the ForceMode.Impulse parameter from that call

oh and you'll want to make sure that your rigidbody has drag and friction otherwise it will just slide forever

[trail gull]

    private void OnCollisionEnter(Collision collision)
    {
        if (other.TryGetComponent<Walls>(out Walls walls))
        {
            Debug.Log("Hit wall")
        }
    }

this is my code, I have an empty object called 'Walls' with the children as all of the walls of my map, why am i getting this error?

The type or namespace name 'Walls' could not be found (are you missing a using directive or an assembly reference?)

[summer stump]

Do you have a class called Walls ?
Object name is irrelevant here

[trail gull]

I dont have any code for my walls, they are kinda just there

[polar acorn]

What is Walls

[summer stump]

Ok, then that is why
You have no component called Walls

[slender nymph]

you cannot use a type that does not exist

[trail gull]

Oh

using UnityEngine;

public class Walls : MonoBehaviour
{
  
}

would I just do that?

[summer stump]

If you want, sure
We often call that a "tag script"

[trail gull]

Are there better ways?

[polar acorn]

Tags

[summer stump]

Having the Walls class actually DO something...

[polar acorn]

But you only get one of those

[lofty sequoia]

like maybe use the OnCollisionEnter on Walls

[topaz gorge]

How would i access the Unity Transport Bool Allow Remote Conneciton through a script cant seem to find it anywhere

[rich adder]

what ?

[mystic oxide]

Can someone explains to me what is Wwwform class? I still dont get it, is it creating an temporary form or generate form data to a server

[wintry quarry]

it's an object that will wrap the data up and send it to the server (via UnityWebRequest) in the same format as an HTML form i.e. application/x-www-form-urlencoded

[mystic oxide]

Gotcha, thanks!

[full iris]

hello, I'm trying to bind an Event for this PlayerInput (from Input System: https://docs.unity3d.com/Packages/com.unity.inputsystem@1.3/manual/Installation.html), but I'm not seeing the public methods of another script that's attached to the same object that PlayerInput is attached to. is this a bug?

[wintry quarry]

you dragged and dropped the script (from your project files) instead of the object that has the script attached to it (from your scene/prefab)

[full iris]

😌 Oooooh thank you so much! @wintry quarry

[deft quarry]

I have a basic player movement script going so far and I aim to incorporate a double jump. I believe i've set up my logic correctly yet I can still jump infinitely. Can someone help me and point out where I went wrong?

https://gdl.space/kaxiqapuso.cpp

[buoyant knot]

you should really avoid variable names like dJ. it makes it like impossible to understand

[deft quarry]

Sorry, kinda forgot other people might be seeing this so I just used variable names that made sense to me

[buoyant knot]

you should also use better variable names for yourself

the most likely person to read your code is yourself several months/years in future, when you no longer remember wtf you were doing

[deft quarry]

You're probably right, i'll work on it.

[buoyant knot]

i recommend splitting jump check from executing jump

jump function should just be in charge of executing a jump. not checking logic to see if a jump should be possible

single responsibility principle, especially since those responsibilities might become more involved

[deft quarry]

Good point, should I just keep them in the update function instead?

[buoyant knot]

your isJ bool isn’t being changed when you call jump

[buoyant knot]

I would. Or make a separate function to check, so Update can be slim

Update in movement scripts tend to get really busy, so you want to be super organized

[deft quarry]

Why isn't my variable being changed? My single jumping was working, but then I attempted to add a double jump and thats when this started

[rich bluff]

because bool is a struct

it is copied

you send a copy of it into the ground check method

you change that copy

original stays unchanged

[deft quarry]

Oh shoot, i forgot about that

That explains so much

[teal viper]

*value type to be precise

[buoyant knot]

i cannot stress enough how much 1-2 letter variable names are cancer

[rich bluff]

public struct Boolean

[deft quarry]

Is there any way I can pass the isJ variable into the function and have the actual variable be updated and not just the copy?

[rich bluff]

yes

ref modifier on the parameter

or just return

return j;

[buoyant knot]

don’t use ref

GroundCheck should return a bool.

isJumping = GroundCheck();

which also makes it obvious why that line is wrong

because you should not be setting isJumping to a value depending on ground when you know you just jumped

player state should also be an enum

i think he’s gone now

[deft quarry]

im not

just thonking with my below average noggin

[deft quarry]

Can you elaborate?

[static cedar]

I can always send some guy's BulletLogic function which contains all the functionality, and hit reg all in one massive function, multiple nested loops, string comparison, and two letter names.

[deft quarry]

That sounds like aids

[static cedar]

It's a code from a flash game when he was pretty new to it.

[deft quarry]

Im actually curious now. Do you have it? I'd love to see it

[silk night]

Sorry for the late ping, just saw something in your code, instead of using GetComponent(typeof x) as x you can just do GetComponent<x>()

[static cedar]

I'm on phone rn but I sent the file here.

Lemme just search it.

@deft quarry

[deft quarry]

Thank you!

holy hell thats eye bleach worthy

[static cedar]

ActionScript, TypeScript but the safety isn't imaginary guardrails, it actually exists.

[full iris]

ahh that's much better. thank you vm @silk night

[silk night]

I need a longer screen.. that nesting..

[static cedar]

[silk night]

Please tell me that is autogenerated and somebody didnt lock their dev into their basement until that was written

[static cedar]

It's also decompiled code.

But I'm not sure why the loops turned into a while loop with the index outside.

I'm not perfectly sure if it's actually built like that to begin with.

[buoyant knot]

in grad school, i inherited code for a tribometer that was like that. one letter variable names. highly technical math from an obscure paper on highly specialized machinery. Over 2000 lines of code, with the only comment being one random comment with a paper citation

We gave up and just told our PI “yeah, the machine isn’t going to work.”

[silk night]

Yeah thats why i understand the variable names, but the nesting doesnt suddenly pop into existence when decompiling something 😄

[buoyant knot]

PlayerState enum with values for Jumping, Grounded, DoubleJumping…

this way you don’t handle a bunch of bools that should be mutually exclusive

[static cedar]

I'm sure with the nested ifs though.
He definitely didn't want to use AND since he used both AND and OR sparsely around so it's not just the decompiler.

[deft quarry]

Oh, okay, thank you!

[buoyant knot]

my issue was that we didn’t understand the math since we didn’t understand wtf the variables represented, nor their units

if we knew the units, we could try to infer what they meant, but no dice

[static cedar]

Sounds like he converted the research paper into code.

Also they bought that reason?

[buoyant knot]

it was true

i was the most computer saavy guy in the lab. if I say “it’s not happenning”, then it is simply not happenning

[static cedar]

Seems legit.

[buoyant knot]

in the land of the blind, the cyclops is king

[rich bluff]

the enjoyment of the biggest fish in the pond

[deft quarry]

Sorry to be back here, but how would I check to see if I can double jump or not? I've tried almost everything I can think of, and I cant seem to get it.
Updated Code: https://gdl.space/eluzexegel.cpp

[gaunt ice]

Do you know that you can modify class properties in method?

[deft quarry]

Yeah, is the answer simple and im just on the spectrum?

[summer stump]

Have an int. When you jump, add one. If it's less than 2, you can jump again. When you are grounded, set it to 0

[deft quarry]

I thought of that, but thought it would just add more variables to my code when what I had would suffice.

[summer stump]

Ah, you have a doublejump bool

So use that?

You have a doublejump method too?

I feel like this is way more convoluted than an int

[deft quarry]

Thats the goal, i've tried using that almost every way I know how.

[summer stump]

I would get rid of that and the doublejump method and just make the jump method add one to an int.

Make it much more simple and clean

[deft quarry]

That

is a good point

[rich adder]

so many bools

this hella messy

[deft quarry]

Yeah, im not the most experienced

[summer stump]

Wait, also do you have compile erros? Your Jump method has an isJump bool (why?) but checks isJ

Why does the GroundCheck method have a bool passed IN?

[deft quarry]

No, I changed that before posting to try and make variables more clear and guess I missed one

[summer stump]

Ah ok

[deft quarry]

It was mainly used for when I had my double jump boolean as well as my normal jumping boolean so I could set each one with only one function

very inefficient though

[true pasture]

how do you check if callbackcontext is null basically? I cant do context.cancelled for reasons.

(couldnt find anything online that worked)

[wintry quarry]

why would it ever be null?

What are you trying to do

btw it's a struct so no it can never be null

[true pasture]

so im jumping and when I let go of jump, I was trying to check for when it was let go (or no input). but I cant use context.cancelled because they are on different scripts. the jump is actually started from onenable but what enables the jump state is the jump input on another script

[wintry quarry]

but I cant use context.cancelled because they are on different scripts
This doesn't make any sense at all

[true pasture]

lol im sorry

[wintry quarry]

do your input handling as needed, using canceled to detect when the button is released

communicating that with another script is a separate concern

[summer stump]

I feel like you just... want ctx.canceled.
When the one script gets that callback, send that information to the other script

[true pasture]

only 1 script is enabled at a time

how would I send context to another script

[summer stump]

Subscribe the other script to the event when it is enabled

And a disabled script can still accept and run code. Just not run Update and (unfortunately to this situation) receive input callbacks

[true pasture]

im sorry what

thats news to me

[wintry quarry]

what does scripts being enabled have to do with anything?

[true pasture]

apparently nothing

[wintry quarry]

enabled only determines when Unity callbacks are run on your script. You can call functions as you please regardless of the enabled status

[true pasture]

unity events for input wont run from a disabled object though right?

hopefully that made sense

[wintry quarry]

If you're using the PlayerInput component I don't see why the object it's attached to should/would ever be disabled

PlayerInput is 1:1 with a human player

[true pasture]

yeah i mean the object you plug into the events

[wintry quarry]

that's not relevant at all then no

It will still run functions on a disabled object

[true pasture]

that ruins my state machine then? (not asking like you know)

[wintry quarry]

Is that a question or a statement?

[true pasture]

all these objects have scipts that do stuff on the playerinput component. youre saying they are always running the callback context in their functions?

[wintry quarry]

wdym by "running the callback context"?

[true pasture]

they each have functions that accept callback context

and theyre running while the opbject is disabled according to you?

[wintry quarry]

If you mean that you've assigned functions on them from the PlayerInput component inspector unity events, then yes

they will run

assuming the PlayerInput itself is enabled / active

[summer stump]

Are you sure? I thought that they would no longer receive the callback event if the script was disabled. Someone said they tested it, but I did not yet

[wintry quarry]

Well now you're all making me question it haha

But C# events definitely don't care

I guess its possible UnityEvent checks but I'd be surprised

naturally the docs are silent on the matter

[true pasture]

trying to test rn lol

[slender nymph]

considering objects can be enabled from unity events, i don't think them being disabled is going to prevent anything from happening when the unity events are invoked

and you can still call methods on disabled objects, it's just certain unity messages are prevented like Start, Update, and FixedUpdate

[true pasture]

yeah looks like it runs while disabled fml

[sour fulcrum]

you can just check if its enabled

[true pasture]

u right that will prob be easiest ty

[wintry quarry]

or rather: https://docs.unity3d.com/ScriptReference/Behaviour-isActiveAndEnabled.html

[true pasture]

ty for the help Im still not sure on the context for my first question but I need to fix this right now

so for this why cant I use gameObject.isActiveandEnabled. it only lets me do this.

in the docs they say it checks a GameObject

[wintry quarry]

gameObject doesn't have that property naturally because it doesn't make sense

not sure why you would want to use gameObject

[true pasture]

oh good point im not supposed to be using the current object (wait yeah I am lol)

whoops

[gaunt ice]

I didnt know anything about new input system, but why the fsm is in forms of gameobject

[true pasture]

my medicines worn off dont flame me😭

[rich bluff]

its fine, convenient way to represent and work with fsm

only problem is that if the hierarchy with it is moving you are adding pressure to the scene graph

[gaunt ice]

adding a debug panel is easier for me…..less gameobject needed but your scene will be mess

[quiet eagle]

how do i reference classes defined in separate scripts?

do i have to have a reference to it or something>?

[rich bluff]

check pins

https://unity.huh.how/references

[wintry quarry]

yes, you must get a reference to an instance of a class in order to interact with it

[quiet eagle]

unity.huh.how LMAO

i love that

[hexed valve]

Text is a legacy type of component you

[quiet eagle]

tyty

[wary sable]

How would I grab a refrence to an asset from its path?

[rich bluff]

AssetDatabase

get guid from path

get asset from guid

[wary sable]

tyty

when using CreateInstance for a scriptable object, does unity actually create an asset?
or will it get GC'd after runtime?

[rich bluff]

it creates it in memory

you have to write it with AssetDatabase

[wary sable]

ok cool, so I can use createInstance and createasset separately without issue

[rich bluff]

it can be a way to leak, because any unity object represents native resource which may not be cleaned up until you call Destroy on it

[wary sable]

would calling destroy on the reference to the SO after its been created as an asset destroy the asset?

[rich bluff]

all my code uses AssetDatabase.DeleteAsset for that i guess it will just throw if you try

i imagine i would be like - destroy instance in memory, see it still serialized on disk, reimport, instance created again but ref invalidated, invalid state

[wary sable]

gotcha, I was only asking since you said that it could cause a memory leak, that if it was because there was a version of the SO in memory and in storage that I would possibly need to clear the one in memory to prevent any problems

[rich bluff]

any SO that has backing asset is in essence bound to that asset, unbound instances are "unmanaged" by unity, so their lifetime control is on you

[wary sable]

ok, so would this be considered bound or unbound?

                AssetDatabase.CreateAsset(attackSO, "Assets/Custom/Player/Combat/" + item.name + ".asset");```

[rich bluff]

bound

[wary sable]

wonderful

[rich bluff]

unity will associate now this instance with the .asset

people use SOs for runtime representation as well, cloning or creating in place for various use, so i mentioned the general leak possibility

[wary sable]

I was able to get it working, thanks so much for all the help you are a life saver

actually one more thing, I tried to use CC's like you suggested and wanted to make sure I'm using them correctly, does this look good?

||I know "no screenshots"||

[rich bluff]

yep

another one to know is DEVELOPMENT_BUILD

[rich bluff]

if thats inside Editor folder you dont need the guard

[wary sable]

DEV_Build is actually super nice to know tyty

[wary sable]

oh I didnt know that you needed to make the folder lmao

[rich bluff]

you dont need but you can and should

it will automatically compile everything in it into editor assembly

[wary sable]

I definity will add that rn

[rich bluff]

folder can be anywhere and you can have any number of them

same as Resources and Plugins

[queen adder]

How do you usually handle NRE's that happens when you stop playmode, is it good to be ignored?

does that NRE's even happen in the actual game?

[wintry quarry]

With defensive programming

Generally you shouldn't have any NREs in any circumstances

[rich bluff]

are those NRE's or "destroyed but still trying to access it"?

[queen adder]

yea that thing

[wintry quarry]

check for null before accessing references which may be null (or destroyed in this case)
that means if (thing != null) checks in your OnDestroy and OnDisable code

[rich bluff]

        public static bool IsNullOrDestroyedSilent(this object uobject)
        {
            try
            {
                return !(uobject as UnityEngine.Object);
            }
            catch
            {
                // swallow the exception
            }
            return true;
        }
``` hacky way to get around that

[queen adder]

it's just annoying to have to check them when they are meant to be like always active :<

[wintry quarry]

all objects in the scene are destroyed when the scene is unloaded

disabled first, then destroyed

[queen adder]

they're like permanent thing, but closing the game breaks the rule

[queen adder]

isnt try-catch system more expensive than the normal null check?

[rich bluff]

yeah, if it throws

Mornin' all. More adventures in gravity.

Would someone be willing to take a quick look at this and give me any pointers please?

https://pastebin.com/SFVvj4rr

I'm basically changing the gravity vector on the fly to simulate planetary gravity (spherical world etc)

I'm using a rover as an experiment, I have the driving around the planet etc. all sorted and working.

The part i'm interested in is.....

    roverMass = roverRigidBody.mass;
    float gravityForceOnObject = roverMass * gravityForce;
    roverRigidBody.AddForce(-gravityVector * gravityForceOnObject);

what I'm now trying to do (that will be applied to a ship object later when it's working), is to counteract the gravity, so that my eventual ship will 'hover' automagically. I think I have my gravityForceOnObject calculation wrong because currently instead of hovering, the rover just flies straight up (although in the correct direction).

[wintry quarry]

You're multiplying gravityForce into the force twice

Once in the first gravityVector calculation and again in the gravityForceOnObject calculation

[ruby python]

Oh....of course I am. So the gravityForceOnObject is completely redundant? lol.

[wintry quarry]

The canonical way to counteract gravity would be:

rb.AddForce(-Physics.gravity, ForceMode.Acceleration);```

Note that in a game with custom gravity directions using Physics.gravity is probably not going to work out for you since it's global

[ruby python]

Aaaah, okay. Yeah that makes sense. Sorry, tend to glass over a bit when it comes to physics stuff. lol.

[wintry quarry]

Usually custom gravity through AddForce is in the cards

[tepid cobalt]

Can you add a seperate artifical gravity to your objects to countteract?

[spring hemlock]

How do I pass stuff like GameObjects into FSM scripts?

[ruby python]

I haven't implemented it on this specific script yet, but the gravity 'range' is limited for each planet (ie, big ass trigger that turns it on and off for each planet with their own vectors and strengths.

[wintry quarry]

As parameters to functions or constructors

[tepid cobalt]

cool

[ruby python]

Hmm. Okay, so doing this had the same effect, the rover just goes straight up. I'll keep plugging away at it. lol.

[wintry quarry]

Show code

[ruby python]

void Update()
    {
        gravityDirection = currentPlanet.position - transform.position;
        gravityVector = gravityDirection.normalized * gravityForce;
        Physics.gravity = gravityVector;
        roverRigidBody.AddForce(-Physics.gravity, ForceMode.Acceleration);
    }

[wintry quarry]

You're calling AddForce in Update

AddForce should only be called in FixedUpdate

[ruby python]

ah, bugger. lol. Thank you.

Yeah that works, thank you. Thinking about it, would it be better to put all of that gravity code in FixedUpdate?
