Google blender to unity export/import settings. They use a bit different coordinate space

woven crater
#

do i need multiple text component for each item component like item name and item discription that is display on the same image object parent?

verbal dome
#

When?

knotty gust
# verbal dome When?

like when the script is added to an object i want it to be added to an array on another object instantly in the editor instead of having to add the object in runtime

verbal dome
woven crater
#

thank

unreal phoenix
knotty gust
gaunt ice
#

you can drag the object to the array slot in other object, unless you think making a script to do this is better

knotty gust
#

i wanna try using a script cus theres already alot of objects that need to be added in the scene

#

think it would be better so i dont risk missing any

verbal dome
#

You can try one of the built in methods: Reset, OnEnable, OnValidate

#

Reset probably makes the most sense here

#

Gets called when you add the component

#

(Or manually from the component's context menu)

#

The object with the array must probably be marked dirty after you do that tho, so that it saves the change with the scene

potent echo
#

Figured I could also use direction = (Random.Range(0, 2) == 0) ? -1.0f : 1.0f;. Unity needs an official Random.choice though, I wonder why it doesn't exist.

What's the problem

wintry quarry

(Random.Range(0,2)<<1)-1;

thats useful thanks

Im pretty sure thats needed, anyway

#

ohhhhhh

#

Or is the object with the list/array created afterwards?

nahhh i see what u meant

Well I have given some comments alos

Also so can you guys pls check the codes?

And what are issues in GitHub?

anyone know why ```yield return new WaitForSeconds(0.5f);``` wont trigger? like it starts the  changeColorBack() but it does not excute anything after the debug.log
keen dew
#

I'm guessing the object this script is on gets destroyed

elfin eagle
#

no it gets hidden, maybe thats the problem then

wintry quarry
#

Coroutines will only run on active objects

ahh ok I thought it also worked on deactivated as well

thanks

hey post code properly with link !code

#

thanks for being patient

rich adder
vestal adder
#

nothing shows up in the debug log for collision so i think its that

rich adder
#

well your first mistake is thinking you can have 2 tags on the same object

#

so Tag1 && Tag2 can never be

vestal adder
#

i should get rid of the second tag?

rich adder
#

why does the gun have OnCollisionEnter in the first place

vestal adder
#

thats supposed to be for the bullet colliding rather than the gun

#

the script is on the gun tho

rich adder
vestal adder
#

oops

rich adder
# vestal adder oops

not even sure why gun would have a collider in the first place.
What are you trying to accomplish with that exactly , there. is prob a better way

vestal adder
#

i would like my bullets to disappear after hitting stuff

#

right now they just sit there

rich adder
#

and put OnCollision enter logic there

vestal adder
#

how would i make the script on the bullet not destroy the bullet prefab

Hey I need some help with animator.SetBool I have the getcomponent but still not working say animator does not contain definition

Hi! Im currently trying the Alteruna Multiplayer and can`t fix one error. If needed, I can provide my code. The Error: No matter what I try, as soon as I leave the Lobby there are no Cameras rendering onto the display. It could be a conflict between my PlayerController and the camera, because the PlayerController says playerCamera = camera.main. I looked into the scene while the game was running and there were no cameras. At the start (before I join a Lobby), everything works fine. Thank you

rich adder

the prefab never goes in the scene

#

the one in the scene that the code actually runs on is a copy

the code will never actually run on the prefab itself

why this return null? i set the artifactlist SO in the inspector and the list is not empty

vague stag

hello

woven crater

ah.

green briar
vague stag
# woven crater why this return null? i set the artifactlist SO in the inspector and the list is...

It looks like you're talking about a C# or Unity based piece of code. In the situation you mentioned, when you set a list named "artifactlist" to "SO" (ScriptableObject) via the inspector, there may be several reasons why the list returns empty:

There may be an error that needs to be taken into consideration when adding data to the list. Data addition may not have been done correctly.

The "artifactlist" list may be a part of your code that needs to be populated with the data you expect. It is useful to check this situation.

It may be the case that the "artifactlist" list you may have set up on the Inspector has a reference to a different list in your code. To check this situation, it is useful to review your code and inspector settings.

By gaining control over these cases, you can determine why the list is returning empty and update your code accordingly. If you need detailed help, you can get more specific help by sharing your code snippet or Unity project details.

woven crater

tldr
i just forget to create instance of the list

how do i set image?

river roost

sprite

woven crater
#

nothing?

image.png
rich adder
# woven crater

also you should prob have a method on these objects for that

rich adder
#

remove using System.Drawing from top

river roost
gaunt ice
#

you should create a custom class and store the reference instead of relying on getChild(X)...

river roost

hey

if it works it works

you should not aim to write brittle code

what if somehow you only had 2 child. your whole thing breaks

imagine you fix your ui someday and your code no going to work anymore

also getchild performance is terrible

But really - don't do this

it's awful

woven crater
#

okay.

wintry quarry
#

direct references

rich adder
woven crater
#

understandable

spring skiff
#

What can I do, If I have a "void OnCollisionEnter", that doesent react if I move a Collider with Trigger enabled to it?

cosmic quail
#

and its the right one

wintry quarry
rich adder
#

they're using Image from System.Drawing

#

which is a Microsoft class

wintry quarry
#

Did you forget using UnityEngine.UI;?

cosmic quail
spring skiff
rich adder

river roost
# woven crater like a class that store EVERY reference? 
public class ArtifactUI : MonoBehaviour {
  [SerializeField] TextMeshProUGUI _nameText;
  ...

  public void Set(Artifact artifact) {
    _nameText.text = artifact.itemName;
    ...
  }
}
```you would do something like this, and then call `Set` from your original script
cosmic quail
# rich adder nah says it right here

true i did not see that. i just saw "Image" and "thats not the right class for image" and suddenly i thought i have been using images completely wrong 😅

hi guys i have a question anyone know how can i put the character on the dungeon?

like spawn on it

rich adder

timid hinge
river roost
rich adder
# timid hinge how?

where do you wanna spawn it?
probably easier to make a gameobject and spawn it from there
You can use gameobject brush so you can use the tilemap/grid snap

timid hinge
#

like here

image.png
woven crater
#

well not alot my game is not that big

gaunt ice
#

then reference your own script

river roost
gaunt ice
#

(store them into a list, dont use list<gameobject>)

woven crater
rocky canyon
#

you'd want to spawn it first

#

and get a reference to the instance of the spawned component

#

OK so I think I need some hep with my code where should I look to add animation to an fps Controller?

toxic pasture
#

I'm having an issue with a very basic thing. Whenever I set an object as a child of the other object, it retains it's world position but doesn't retain it's world rotation. I'm trying to make a script that when a key is pressed, the box will become the "held box" and be snapped to a specific position. This position is set by an empty 3d gameobejct which kinda acts as a socket. The box is supposed to snap to the socket and then follow it as the player moves. When picked up, the box snaps to the socket, but afterward it remains in the spot where it was picked up. It moves to camera rotation but not when the player moves.

rocky canyon
#

it retains it's world position but doesn't retain it's world rotation.

#

? care to fix that or elaborate? lol

If im reading this correctly when u set the worldPositionStays parameter of SetParent() to false it doesnt change transform (Position, Rotation, and scale)

river roost
summer stump
rocky canyon
#

does the object have a rigidbody or soemthing on it?

toxic pasture
#

however I disabled it when I pick it up

woven crater
rocky canyon
#

the smartest person in the room is the normally the quietest

toxic pasture
queen adder
#

Yeah i said that backwards sorry

#

You could just manually set the rotation tho

summer stump
toxic pasture
#

rotation isn't the issue

#

position is

queen adder
#

Oh?

rocky canyon
# toxic pasture yes

i do testing when i get problems like this.. and i try to break it down into bits i can understand..
in this case I would take the object and parent it to the socket.. move it where it needs to be and just test that singular thing..

toxic pasture
queen adder
#

Ur setting the position to Vector3.zero?

rocky canyon
#

if it follows the player and acts as it should from the git go.. you can take in that information and move onto the next kink in the chain

toxic pasture
#

picked up and rotated

image.png
#

picked up, rotated, and moved

image.png
toxic pasture
#

line 35

#

potentialObject.transform.SetLocalPositionAndRotation(Vector3.zero, Quaternion.identity);

toxic pasture
queen adder
#

Aight just so i understand correctly

#

The box doesnt follow the player when the player moves
But when the camera rotates it does move

#

Could u possibly share a video of the problem?
With the game view and scene view running at the same time in it

#

also on line 67 i believe you only need to set the parent of the _currentObject once instead of doing it in Update

rocky canyon
#

any sort of mis-scaled object will have adverse reactions to the chain of children below

#

maybe something there? not sure tbh.. keep trying/ asking if it doesn't surely someone will come along and know

summer stump
#

I agree with Vee
Line 67 is an issue. Try commenting it out
You already set parent in PickupItem

I imported 2 pngs im going to put inside my canvas as UI, but it imported as textures, and cant be dragged into unity. How do I turn it back to normal?

Click on the .pngs and then go into the inspector set the type to Sprite 2D

I have a rly weird problem with my room. I have a platform at X 67.78 and to the right of it is an empty object which says its at 17.74. This should be impossible and every platform matches up correctly, i have no idea wth is going on

wintry quarry
#

aka position relative to the parent

#

they are not world space positions

waxen oracle
#

Ooohhh

#

thank you that makes sense

#

Is there a way to see the global position

rare basin
#

with custom inspector - yes

#

with default inspector - no

#

only via code

#

Debug.Log(transform.position);
Debug.Log(transform.localPosition);

waxen oracle
#

Oh using the log

#

yeah alr ill try that

hazy crypt
#

any reason for that?

#

it doesnt seem to have any affects on the gameplay

#

but it only happened with the new font

frosty hound
#

Looks like an editor bug, so can just ignore it if its not affecting you

vast tangle
#

Im not sure what happened but I can no longer activate my start button, it refuses to execute my StartGame Method

NEVERMIND fixed it, i was missing the Graphics Raycaster... must've deleted it by accident

i made a new tile palette but when i place then they appear really small im not sure what i need to do to make it so they fill up the size of the grid

If, for example, it is 8x8, the ppu is 8

so i ran into an issue with this guide and I don't see any issue were I went wrong but I can't figure it out. When I'm spawning pipes I kept x the same y gets change to any postion that it can new Vector3(transform.position.x, Random.Range(lowestPoint, highestPoint) and z stays the same and when i run it nothing happens and so im lost

summer stump
rocky canyon
#

yea, im sure not sure which one tho, art-asset flow, or 2d-tools mab

#

for general stuff u can use unity-talk, and stuff like window, and the layout panels

summer stump
#

I feel like Art Asset Flow is for third party tools. But could fit. I dunno haha

I don't go in those very often

serene barn
#

I'm generally stuck on one part of a flappy bird code and I had to restart to figure what I did wrong but I did nothing wrong and I'm just wondering if it's the code

rocky canyon
rocky canyon
#

did you follow the tutorial and take it step by step?

serene barn
#

I made unity crash because I change one thing

rocky canyon
#

im inclined to think if you did it would have been working up until the part / error in the code you say it might be

#

oh, well easy, change that thing back.. lol

#

and its probably b/c of that bit, might share the code

I can't figure out what is wrong

summer stump
rocky canyon
#

the loop where ur pipes run is probably never ending

#

somehow

serene barn
#

Can't get the pipes to randomly spawn on the y

rocky canyon
#

just create a value, with a random.range value or something

#

and then plug that value into ur spawn position

summer stump
eternal falconBOT
rocky canyon
#

on the y access

#

and if the tutorial is old and has remained up the code is probably fine in that tutorial

serene barn
#

Vector3(transform.position.x, Random.Range(lowestPoint, highestPoint) this is the line of the code that should of made it random, the 2 variables are lowest point and highest point

it needs to be configured for use with unity so you get proper syntax highlighting, autocomplete, and error underlining.
having a configured IDE is also a requirement to get help here

That does not change those values. It creates new ones based on it
They are still 0.
So your two values are just a range from transform.position.y to transform.position.y

serene barn

so every single time you spawn a pipe it spawns at the same exact position as the object spawning them

changed two variable hope it doesnt freeze

oh god

how about actually describing what your current issue is

Set HeightTop and HeightBottom to something other than 0. Like 10

yea I've looked over this so many times and just can seem to figure out what's wrong. I've changed values, ive change variable locations and not to sure what is the issue and dont say remove this or it can end up spawning way to many pipes and freezing unity

did you change the value of heightTop and heightBottom in the inspector

instead of just removing it on the current pipe

heh?

each pipe that spawns will spawn another pipe basically lol

Whenever you spawn a pipe that pipe spawns a pipe and then that pipe spawns a pipe and then that pipe spawns a pipe and then -

An alternative approach to a timer could be either a corouttine, or what I do often is use Time.time to store a kind of "timestamp" and subtract the difference, for example:

public float delayBetweenInput = 5f;
float timePassed;

void SomeFunc()
{
if(Time.time < timePassed) {return;}

//do logic...
timePassed = Time.time + delayBetweenInput;
}

So in that example, spamming SomeFunc will only fire the logic every 5 seconds, this way you dont need to constantly iterate a value over frames (deltaTime), though both approaches are viable, just an alternative

uncut hornet
#

alright cool, ill try both. thanks you all

#

ok so i might be dumb but when using the first example, im encountering this bug where spamming the E button would set the timer back each time, which is how its written out. im just not sure how i can check if the dash happened

#

im pretty new to programming

Put a debug log on the dash function to check

# distant prairie hey guys did someone have the same problems recently? i cant find anything on go...

Ive never gotten that specific error before but I have gotten library package errors before, some things you can try:

  • right-clicking the package from your project browser and "Reimport"
  • make sure you have the latest version of the package in Package Manager (in your case, Rider Editor"
  • if all else fails, you can also try closing Unity and delete your Library folder (it will be regenerated when you open your project again)

This last option will increase the time it takes for your project to reopen though as that folder tends to be >50% of a projects total size most of the time, but then re-opening your project every other time after should be faster once its generated

#

sorry if my wording is off

#

my first thought goes to a bool but like i literally dont even know where to begin with that honestly, and i feel like theres a better answer

fierce shuttle
uncut hornet
#

its pretty not good lol

#

im like brand new to c# and coding in general honestly so yeah

#

so i should make a function for the dash?

#

OH YEAH the *50 is like way over so that i can actually see if it works haha

fierce shuttle
# uncut hornet so i should make a function for the dash?

You dont have to, its just often more "clean" to do so - as Kiatu suggested, after you set your dashTimer to 3, you can add a Debug.Log and put anything you want in it, such as Debug.Log("dashed"); - if that gets logged to the console every 3 ish seconds, you know your logic works, if not, then its possible your timer is not being decreased or there could be another problem

uncut hornet
#

also, this is definetly not right. feel free to laugh ha

and when i tested it it worked because i couldnt dash until after a few seconds after i started the game

Glad you got it working - also if youd want to get some more practice with C# in general, id suggest the w3schools course, its completely free and has interactive lessons on the site - once your familiar with that, you can also try Unity Learn for Unity specific beginner tutorials, though if you feel youd like more info on C#, theres always MSDN and C# playlists on YouTube that cover more advanced topics, just some suggestions if your inclined, GL!

Hey all, I'm trying to make a simplistic chess game as my first unity project and currently im setting the foundations for how the Pieces and the Board will be defined, so far i have a namespace called Pieces than i plan to fill with a class for each piece in the game, an example shown by the class Pawn.

namespace Pieces
{

    interface IPiece
    {
        public Vector2Int[] GetValidSquares();

    }


    public class Pawn : IPiece
    {
        public Vector2Int[] GetValidSquares()
        {


            return null;
        }

    }



}

I want to be able to reference a piece such as Pawn in the Square class, however as they may be different types, I cant define it the usual way, would i need to use generics for this, or is there a better approach? Hope that makes sense

using UnityEngine;
using Pieces;

public class Board : MonoBehaviour
{
    public static Square[,] boardSquares = new Square[8,8];

    public class Square
    {
        

    }
}```

Basically when you have
CurrentInfo a;
CurrentInfo b;

Then after doing
a = b

And when you modify a it also modifies b

#

Because it is a reference type

well my plan was to have a 2D array of squares as shown in the second snippet, then each square contains properties describing whether or not the square is occupied, the piece on the square, etc. I want to reference the piece on the square in the event that it is occupied. However, the current way im doing it, each Piece is a separate class, so if i want to reference a piece within Square, there is no singular type i can use. Which is why i was asking whether or not there was a better way than using separate classes for each piece type

Ah, then in that case I think the multiple classes makes sense, your Square can just hold that IPiece or a list of them if you prefer, you should still be able to do .GetType and check if its a specific piece if you need that info, or have it a part of your interface - if some pieces need to do different things than whatever logic each piece has for their version of GetValidSquares, youll then need to be able to cast to that type, otherwise the class "Knight", "King", "Pawn" etc shouldnt need to be known for their independent logic, though I could be wrong

# inland cobalt Gotcha thanks, I think i'll need to read up a bit more about interfaces

Personally I dont use them too much outside of cases like dealing damage to different things, I could put a IDamagable on a breakable crate, glass window, vending machine, enemy, car and even the player for example, all very different things with very different functions, but they all have "health" and therefore all take "damage" so whatever bullet or blunt object hits them, I dont care what was hit, just something that CAN take damage (IDamagable) was hit, then the object/class decides what to do after (glass might shatter at 0, a enemy might ragdoll, etc) - in your case, that kind of logic may or may not be useful to you but they are certainly worth looking more into, I believe the "abstraction pattern" uses them often

Okay so i've just scrapped the interface as like you said it probably wasn't necessary. So I now have something like this for pieces:

namespace Pieces
{

    public enum Colour
    {
        White,
        Black
    }

    public class Piece
    {
        public Colour colour;

    }

    public class Pawn : Piece
    {
        public Vector2Int[] GetValidSquares(Board.Square[,] boardState)
        {
            return null;
        }

    }
}```

Looking in board now,

```cs
public static class Board
{
    public static Square[,] boardSquares = new Square[8, 8];

    public class Square
    {
        public object occupyingPiece;
        public bool isOccupied;


        public void AddPieceToSquare(/*Some piece object here*/)
        {
            if(isOccupied)
            {   // If already occupied, ensure colours don't match

                


            }


        }


    }
}```

I'm trying to define a method to as it sounds, add a piece to a square. And just to make sure, i want to add some logic inside of this function before proceeding with actually adding it to the square to ensure that im not trying to move to a space that is occupied by my own colour of piece, and if it is i want to throw an error as that should already have been handled. However this is where i was concerned about how to implement it before; I cant just simply check the object that is passed as a paramater for it's colour, as i cant define a singular type when there are multiple, so it could be any object which may not inherit from Piece. Basically what I'm asking is how can i make it so that this function takes in an instance of any one of the piece classes such as `Pawn`, without allowing any object. That way i know for certain that they will inherit from Piece, and they will contain a colour property. Hope that makes sense

# inland cobalt Okay so i've just scrapped the interface as like you said it probably wasn't nec...

Following on from this attempting to solve it with generics, i've come up with something like this

using UnityEngine;
using Pieces;

public static class Board
{
    public static Square[,] boardSquares = new Square[8, 8];

    public class Square<T> where T : Piece
    {
        public T occupyingPiece;
        public bool isOccupied;


        public void AddPieceToSquare(T pieceToAdd)
        {
            if(isOccupied)
            {   // If already occupied, ensure colours don't match
                if(pieceToAdd.colour == occupyingPiece.colour) 
                throw new System.Exception("Error adding piece to square, a piece is trying to be placed over another of equal colour");
            }


        }


    }
}```

But im getting the error with the boardSquares 2D array static that the generic requires 1 type arguments, but i thought that was the point of where T : Piece? I'm still trying to wrap my head around this so if anyone could explain where i have gone wrong here that would be appreciated

Hey so I have rigidbody movement and it works but its jittering when I move both the player and camera at the same time. By itself the movement isnt jittery and the camera look isnt either, anybody know what might be the problem? I'm not sure if this helps but the player movement is in FixedUpdate() and the camera turning the player and looking around is in LateUpdate()

inland cobalt
# tacit estuary Don’t use `object`, you can just use `Piece`

Nevermind, I just realised this won't work actually. The occupyingPiece variable needs to be a class like Pawn as an example, or others such as Rook that will be written up when necessary. They all inherit from piece, hence my original idea. occupying piece cannot just be Piece if that makes sense

rb is on the player empty

teal viper

And the camera controller is on the same object?

open vine
#

i think ur right about the breaking on rotating the player. up and down camera movement has no jittering only side movement

#

no camera controller is on the camera child

teal viper
#

Do you have interpolation enabled on the rb?

open vine
#

yeah I have the Interpolate option in the Interpolate field

teal viper
#

Hmm... That's weird. If the camera controller is a child, it shouldn't affect the rb.

#

Aaa

open vine
#

the line that seems to be affecting it is transform.parent.Rotate(Vector3.up * mouseX);

teal viper
#

Yeah, I didn't notice that you're rotating the parent.

#

Why not just rotate the child itself?

#

At this point it's not really rotating the camera, but the character itself.

open vine
#

yeah i have it this way so that the player moves in the direction of the camera, is this a bad way of doing it?

teal viper
#

It is from many perspectives, but mainly because it breaks the interpolation.

#

Ideally, you want to rotate the character in it's own script using physics.

#

The vertical camera rotation can stay in the camera controller.

open vine
#

would making the camera do the rotation and in the player movement script setting the horizontal rotation equal to the child object work?

If you want to learn, the way im doing it is,
I copied almost line for line this guys 3d controller. I then looked at what i typed and tryed to understand what each part does. Not just each line but each word in each line. If i couldnt figure out what something did i just looked up "unity localEulerAngle.y" and that took me to a manual that explained the little thing i didnt understand.

Also first time i tried learning unity i got overwhelmed, and didn't touch it for a year. When i came back i felt more comfortable so i do recommend maybe taking a small break (not recommending a year but still)

rich adder
vestal adder
#

wait nevermind dawg it was easy

#

i just had gravity on the rigibody

final trellis
#

If i had a string such as 1d20 + 4, how would i seperate it into the appropriate variables of rollMin, rollMax and rollMod, and have it be compatible with potential input variations such as 1d20+4, 1 d 20 + 4 and 1d20 - 4

image.png
#

I know i can use the String.Split() method but im not sure about the modifier part

timber tide
#

why strings tho

final trellis
#

because its a user input thing

#

sure i could have seperate text boxes for each

#

but its a lot faster for a user to type in 1d20 + 4 than typing 1, 20 and +4 all in seperate text boxes

timber tide
#

well, two ways I'd parse it. The smart way would be regex, otherwise split search parsing by numerical, alpha, ect

final trellis
#

the hell is a regex

#

that sounds important

timber tide
#

regular expressions, usually useful for longer strings

final trellis
timber tide
#

pattern matching stuff, otherwise manual splitting like above

final trellis
#

because my problem with just using normal split is if the user formats it like 1d20+4, then i cant seperate the max from the modifier while preserving the sign of the modifier

#

i could still do that, and then preserve the original string so I can then search for a + or - in it anywhere

#

but it sounds like a really clunky way to do it

timber tide
#

well, there's obvious matching here so splitting it up into 3 different variables is just a matter of linear appending values until you hit values not numerical

final trellis
#

or i could use regex split bc actually, looking into it

#

I can split on plus and minus signs but preserve them in the output string

timber tide
#

right, usually the best idea especially if you're adding more complex string elements

final trellis
#

the real trouble i think is gonna be my worst enemy

#

input validation

timber tide
#

but if your requirements are small enough I usually just lazy it up and do linear string appending ;)

final trellis
#

true but the more i read on regex the more i feel like its a valuable thing to learn how to use

#

im surprised i havent heard of regex before so thanks for introducing me to it now rather than later lol

timber tide
#

ye, usually used in games to filter out the* 9 hundred variations of a single curse word

swift crag
#

This should be pretty straightforward with a regex

#

(\d+)d(\d+)\s*[+-]\s*(\d+) matches anything like XdY + Z or XdY - Z, and (\d+)d(\d+) matches anything of the form XdY

#

they would grab X/Y/Z into capture groups 1, 2, and 3

#

If I wanted to do anything more complex I might just write a parser

#

oops, i pasted garbage into the Text field

final trellis
swift crag
#

for that I'd need more whitespace symbols!

#

I updated the link

#

As long as it's just one die plus a constant, you could get rid of the whitespace

#

but if you want to parse, say

#

1d6 + 2d5 + 2d4 + 5

#

actually, that'd still be fine. there are symbols in between each thing!

#

1d6+2d5+2d4+5

#

in that case, I would first chunk it up with a regex

#

then parse each entry

#

in that case, I would use ([^+-]+) to match a chunk of text that contains no + or - symbols. That would chunk out 1d6, 2d5, 2d4, and 5 (with extra whitespace). Trim the whitespace and then handle each one individually

hmmm, if im giving the option to have more than 1 sided "dice" be rolled, I should probably modify the expression to preserve the d so the thing that eats the string knows what is another dice and what is just a modifier, also i should preserve the + and -

swift crag
#

[^+-]: any character that isn't + or -

final trellis
swift crag
#

[^+-]+: at least one character that isn't + or - in a row

#

you can drop the parentheses; you'd just ask to find every matching substring

swift crag
#

getting smaller pieces out of a single match

#

another valid option would be to just go one character at a time

final trellis
#

my brain is being fried with these wacky words

swift crag
#

regexes are a lot :p

swift crag
#

still non-trivial if you've never written anything like that before, though

final trellis
#

pain

swift crag
#

i'd start by just handling XdY + Z

#

delete all whitespace to crunch it down to XdY+Z, so that spaces don't matter

#

you can use myString.Replace(" ", "") to get a new string with no whitespace

#

split it with "+-d". if you get 2 results, it's XdY. if you get 3 results, it's XdY+Z or XdY-Z

#

if you got 3 results, check if the string contains +

#

if it doesn't, try -

#

if you got anything else, or it doesn't contain + or - despite splitting into 3 strings, or any of the split strings don't parse into ints, then display an error

final trellis
swift crag
#

Regular string split

#

no regex here

#

You can pass a string with several characters in it to split with any of them

#

oh wait, I am wrong! you actually pass an array of strings. my bad

# 
var results = "2d6+1".Split(new char[] { 'd', '+', '-' });
#

or an array of single characters

#

might as well do that

# 
var results = "2d6+1".Split('d', '+', '-');
#

you may also just write it like this.

#

that's easier to read

#

god the String.Split doc page is so long

swift crag
north kiln
queen adder
swift crag
#

you need to tell us what's actually happening

#

are both LogError methods running simultaneously?

queen adder
#

it's using IEnumerable instead of -rator

#

and no error, but it doesnt do what it's intended

swift crag
#

IEnumerable is something that can give you an enumerator

queen adder
#

took me like days til i realized the messed up

north kiln
#

Do you start coroutines via string notlikethis

swift crag
#

yes, that's a compile error if you actually pass loghotdogs() to StartCoroutine

queen adder
swift crag
#

ah

#

IEnumerator can yield literally anything

queen adder
#

no error

swift crag
#

hence why you didn't get a compile error

north kiln
#

I'm surprised it even runs at all

swift crag
#

and I imagine Unity just looked at that IEnumerable and thought "idk, whatever"

#

you can yield anything you want

queen adder
swift crag
#

most things do nothing

#

like yield return 1000

queen adder
#

it was supposed to stop/slow things

swift crag
#

or yield return "potato";

north kiln
#

oh you're yielding it directly

#

that wouldn't even work fully if it was a coroutine with multiple yields

swift crag
#

non-generic collections my unbeloved

swift crag
#

oops, wrong reply

north kiln
#

you should yield StartCoroutine(...)

#

So if the coroutine actually had multiple yields then it would actually correctly wait for them

so im making a new scene of the project im making i want to add a system to like you press the arrow it rotates left and right but i want it when i hold it it rotates but i don't know if is possible in unity

also just to be sure, I can do a foreach loop for chars in a string right?

#

also lord java and C# being so similar makes their differences so jarring

queen adder

yea that works

#

get enumerator on an ienumerable member

final trellis
#

Im in a college course that involves java, so im used to typing String instead of string now 😭

swift crag
north kiln
#

is it silly 🤔

swift crag
north kiln
#

it yields the IEnumerable

#

which gets passed to Unity, and Unity does shit all with it

swift crag
#

right, I mean an IEnumerator, not the incorrect IEnumerable

#

yield return StartCoroutine(BogusMethod()) would be a compile error

#

which would be nice for catching that

I am fairly sure this has been mentioned around you multiple times lol

It has whatever is declared in C#

because it is the C# reference (CSReference)

queen adder
#

oh, i thought it's just the source that has already been translated

north kiln
#

translated?

queen adder
#

fwom c++ to c# :3

north kiln

It is the source code of the C# portion of the engine

#

the C++ portion is closed source

teal viper

unless you pay some mony

queen adder

hmm, is getcomponent implemented in c++? I cant find anything related to it in c# ref

north kiln

If you see extern that is a call to C++

I dont understand this error with this code because im using things i see on the official documentation

gaunt ice
#

why you name the variable as the name of built in class

uncut hornet
#

oh i diddnt know

#

literally day 2 man

#

im so stupid i just looked at it again

gaunt ice
#

avoid using the name of built in classes as your class name/variable name

uncut hornet
#

and yeah i have another error i was about to address

gaunt ice
#

if(A=B){
}

#

also please dont use == operator for checking float, instead use Mathf.approximately
and you probably looking for getaxis raw (in this case using == is safe)

uncut hornet
#

i feel like the input manager should be easier to understand than this so what do you mean by that

#

negative button is A
Positive button is D

#

simple enough??

gaunt ice
#

getting input has nothing to do on how you compare two floats
btw did you notice that you type = (assignment) instead of == (logical and) in the two if statements?

uncut hornet
#

ok the == fixed it i looked over that. thank you

gaunt ice
#

getaxis returns float in range from -1 to 1, so you probably want to check if the returned value < 0

uncut hornet
#

yeah i did that

Actually, does your rotation script rotate the player transform automatically? I suppose it does so then that "fix" I proposed would just create more bugs

create a property (getter setter) that changes the textmeshpro at once when you change the variable

  }

What do you expect to see? Particles don't have names, the only thing that has a name in this scenario is the object that emits them

A box, spheres, whatever. Yes, that's the most common way to do it

because you do not start Coroutines like that

If you do it like that, it's okay, but it takes a bit of time to set up and another thing is that if you change the scale particle, you also have to change its size box.
