yes, the sarcasm is quite helpful

slender nymph
#

you are the one who insisted that the documentation was wrong even though it was really your code that was wrong

languid spire
#

even though the error message was very, very clear

queen adder
#

I think this has something to do with it being in update rather than fixed update and/or something about it not being executed gradually over time

slender nymph
#

speed = Mathf.Lerp(player.velocity.x, topspeed, rate);
this line is pointless because you are assigning to the local variable named speed which you never use after this line

#

or rather, you never use it for anything other than displaying it

#

also for future reference, when using a site like pastebin where there's no syntax highlighting by default, please have the courtesy of selecting the correct language so that there is syntax highlighting

queen adder
#

ok

rare hawk

rare hawk
# queen adder so your suggesting that its because it IS in Update rather than fixed update?

I'm looking at your code now, but I can say with certainty you should move the physics stuff to FixedUpdate. Also see this article by Unity themselves: https://learn.unity.com/tutorial/update-and-fixedupdate

Also, I would recommend using clearer names. Calling your Rigidbody2D "player" is somewhat confusing, as often the player is the entire GameObject, not just the Rigidbody2D.

Update and FixedUpdate - Unity Learn

How to effect changes every frame with the Update and FixedUpdate functions, and their differences. This tutorial is included in the Beginner Scripting project. Previous: Awake and Start Next: Vector Maths

#

But I have to say, you have a lot of things that do nothing in your code (two separate speed variables, random variables that do nothing, etc.). Maybe look up & follow a tutorial first so you get an explanation of what everything does

i got the PlateCompleteVisual Script here to deactivate the items but it activates it in the game.

#

I want the plate to be empty when it spawns and i interact with it but some of the items are there when i interact with it when it should be empty.

#

this is the script that goes with the plate

guys quick question, what's the "Editor Loop"?

short hazel
# main karma guys quick question, what's the "Editor Loop"?

Everything related to updating the Editor itself. Running editor scripts, keeping the Hierarchy and Inspector windows up to date as the game runs, etc. Won't be there in a built standalone executable so this entire section can be ignored when profiling

main karma
languid spire
short hazel
#

Playing in maximized will ease off the performance hit, as it needs to visually update less Editor things

main karma
#

This means I had no problems with optimization after all, but I'll still try to change my particle simulator with the VFX graph to see if there's an improvement when I figure out how to do that

languid spire
main karma
languid spire
#

well maybe that is why the editor loop is taking up so many resources

main karma
#

basically only 1 scene works atm, and I need to fix the rest for when I build the game as rn I'm testing stuff

#

when using tuples in c# like (int,int) is it by default the value tuple type or the class type ?

#

hovering over it does not tell me if its a struct or class

any good way of activating and deactivating a boolean that is in a raycast that activates only once?

#

boolean that is in a raycast that activates only once?

#

the raycast only activates once

cosmic dagger
#

Uhh, how does the raycast activate once?

#

Wait, do you mean the method is called only once . . .

steep rose
#

it only activates when Getkeydown is true and when it is done getting invoked

#

let me get you the script

cosmic dagger
#

Do you mean the Raycast method is called?

steep rose
#

called only once, yes

#

i made it to do that

cosmic dagger
#

The bool in the raycast. Can you explain that part? I checked the Raycast method(s) real quick and didn't see any bool parameters . . .

steep rose
#

raycast1 = true; is the boolean

#

does the page not have it? should be line 95

short hazel
#

Warning line 105: hit1 will be assigned a new value even if the raycast did not hit anything!

steep rose
short hazel
#

This is because when using an out parameter, it must be assigned a value inside the method before any return is reached

steep rose
#

i get that, i had it as hit2 before but as i said its broken for now

#

will fix it when the raycast1 is fixed

My player won't move to my keypress all of a sudden. It was working before but it stopped now.
I haven't changed anything in the scripts and a new script I made was for something different.

#

Check what code is running with the debugger or logging

#

and make sure errors are not disabled in the Console window

console-toggles.png
steep rose
#

is your playermanager script actually getting your input script?
playerInput = GetComponent<PlayerInput>();

final pelican
#

This is what the debug looks like for the player

rich adder
#

have to put logs in the script make sure they run

north kiln
#

Debug mode is not the debugger to be clear

steep rose
#

it half debugs, not even. put some logs in your scripts like nav said

#

afaik all it does is show private variables in the script.

final pelican
steep rose
#

Debug.log();

final pelican
#

At the end of the code right?

rich adder
#

wdym "the end of the code"

steep rose
#

no, you put them wherever the script is suppose to run

#

if that makes sense

rich adder
#

when in doubt, put it in update

guys i made a pick up tool script and everything works but the only problem is that if i press e at any location it will pick it up how do i make it so that if we press e when we're near the object it'll pick it up instead if being at the other side of the map

rich adder

#

Seems that it isn't picking up where the player is when it starts

Why would one even need to have ANY Variables Private when there are abilities that can make ANY of them public

If u look at the script which "activates visual", see if it actually does anything, since you are following a tutorial maybe this part wasn't implemented yet?

zinc aurora
#

@static wasp the variable you change on the unity is different from the variable you enter in the code

#

the variable in the code is like a start point

then you can just tweak around it

Hey guys.. if I create an UI button.. to find the method here as shown in the SS I always need to create the method as public? no way to create it as private and acces it here some how?

image.png
frosty hound
#

Nope

solemn fractal
#

hmm. ok thank you.

#

if the funcions I have.. as public.. they are inside my UIManager script. I need to drag the UIManager script here correct?

image.png
#

I cant find the functions doing that way. what am I doing wrong?

#

example of one of the funcions:

teal viper
solemn fractal
#

I am dragging the script it self

teal viper
#

Well, the script itself is just a script asset

solemn fractal
#

ok now its fixed

#

thank you

#

already understood what you meant

teal viper
#

It doesn't represent the class that's inside of it.

solemn fractal
#

I dragged the object now UIManager and worked

cosmic dagger
solemn fractal
#

I am trying to find a better name for it.. but I will have a dmgbutton while the game is running or in the menu of the game when you die after it

#

so INGAME its while you are playing.. and not in the menu itself

#

hahahahaha

#

I am very bad with variables names

#

I try my best.

cosmic dagger
#

i'm a bit OCD about stuff like that . . .

oak nimbus
#

how do you add a menu item to this menu. its the one that shows up when you right click a scene in the heirarchy

Screenshot_2024-08-31_215409.png
solemn fractal
#

and trust me I just dont name them I take some minutes to think

cosmic dagger
#

they don't have to be different names unless they're in the same script . . .

solemn fractal
#

They will be in the same script

cosmic dagger
#

oh, that's . . . different . . . 😅

solemn fractal
#

inside the UIManager basically

#

Actually now thinking .. I can have more scripts inside my UImanager object. right? maybe I should create 2 scripts

#

one for buttons inside the game while running and one for when its in the menu

cosmic dagger
#

then you can do _dmgSkillMenuButton . . .

#

oh, i would not have thought they were in the same script . . .

solemn fractal
#

you would not have 2 scripts inside UIManager object you mean?

cosmic dagger
#

i would have a different script for the in-game buttons than i would for the menu buttons . . .

solemn fractal
#

yeah that is great idea I will do that

#

With that I can have better variable names and I dont need to name them with Ingame etc

cosmic dagger
#

the in-game buttons seem tied to gameplay and don't have anything to do with a menu . . .

barren scaffold
cosmic dagger
#

all of the methods? the members from ani? the members from col? it's hard to tell which/what you are asking about . . .

barren scaffold
# cosmic dagger what is supposed to show up?

states() is a local method, and is yellow.
The other methods are from other scripts or the class it is inheriting from, and they show up as white.
When mousing over the states() method, it shows its location and other info.

Main thing is I just want to be able to visually see the methods easier rather than in white.

#

is there a way to increase the gravity of an object?

#

like i want the object to fall fast

lapis frigate
#

hey, when I tried to acsess the player by this line of code I got this error, I think its because the player is a prefab and not a game object, so is there another way to acsess a prefab or this is the way but my code is wrong?

deft grail
#

and does it have the Unit component

lapis frigate
#

it does have a unit componetn

#

but its a prefab

#

does a prefab counts as a game object?

deft grail
#

unless its a prefab IN the scene

#

which that works too

lapis frigate
#

it does in the scene when the game start

deft grail
lapis frigate
#

and like i load it in the scene and the game start

stone pilot
#

I just had a qestion

#

Is there a way I can put this

#

resolution that i use in the editor which is 800 x 600

#

to the build

#

so I can have the pixelated look ?

deft grail
eternal needle
eternal needle
lapis frigate
#

I dont know what I can debug though

#

its just one line

deft grail
eternal needle
#

id honestly change this whole code up though. pass in a reference to the Unit when calling this method and now suddenly you have items that work with any character, its more performant, and wont be completely fragile.

lapis frigate
#

so I had to change it in the code

deft grail
lapis frigate
#

I guess so

static wasp
#

you could name it names like player, camera, player_collision, etc. so unity doesn't get confused

lapis frigate
#

allright thank you for the tip

eternal needle
#

that only applies to if you're naming a class. they were naming a game object

static wasp
eternal needle
eternal needle

Hello, I am making this game in which these red squares will follow around the white triangle (player)

#

here is what I'm using for the enemy follow script

image.png
#

I want to create a prefab of the enemy, but if I bring the prefab in, I have to manually assign the reference of the player to every prefab

#

any way I can directly reference the player in the code?

languid spire
#

normally you would assign that at the point you instantiate your enemy or you could have a singleton which holds the reference to the player

#

also please do not post screenshots of code

plain narwhal
#

sorry

jaunty obsidian
languid spire
jaunty obsidian
#

i will send a video

languid spire
#

no. Again irrelevant, read what I wrote

#

and if you don't know the basics of Unity why are you doing multi player?

jaunty obsidian
languid spire
#

then you should know how to set a refererence in an inspector

jaunty obsidian
#

i know

#

i made this in singleplayer it worked but in fusion it isnt

languid spire
#

irrelevant. The error message is perfectly clear. firePoint has not been set in the inspector

jaunty obsidian
#

i have changed the error code to Runner.Spawn(bulletPreFab, new Vector3(0, 0, 0), Quaternion.identity);

#

it still give that error

#

its because bullet

languid spire
#

if it was bulletPrefab the previous line would throw an error

jaunty obsidian
#

here s player script

player.png
#

btw bullet has its own Rigidbody2D

languid spire
# 
 bulletrb = bulletPreFab.GetComponent<Rigidbody2D>();
        Runner.Spawn(bulletPreFab, firePoint.position, firePoint.rotation); //In here unity says 'Object referance not set to an instance of an object'

first line throws error if bulletPrefab is null

jaunty obsidian
#

but bulletrb is bulletPreFab's Rigidbody2D and bulletprefab has rigidbody2d

languid spire
#

but if bulletPrefab is null then there is no component to get. Nor an object to get one on

jaunty obsidian
languid spire
#

Ok, so possible multiple Player Controllers. Debug your code to see exactly what is happening and where

jaunty obsidian
#

i will try

gloomy bison
#

Will check it out when i get home

stone pilot
#

this is what happens

    {
        anim.SetTrigger("takeOf");

        isDragging = false;
        line.enabled = false;

        Vector3 startPos = line.GetPosition(0);
        Vector3 currentPos = line.GetPosition(1);

        Vector3 distance = currentPos - startPos;
        Vector3 finalForce = distance * forceToAdd;

        rb.AddForce(-finalForce, ForceMode2D.Impulse);

        cameraShake.StartShake();
    }````
#

I call the trigger in the drag end

# 
    {
        if(Input.GetMouseButtonDown(0) && !isDragging && isGrounded())
        {
            DragStart();
        }

        if(isDragging)
        {
            Drag();
        }

        if(Input.GetMouseButtonUp(0) && isDragging)
        {
            DragEnd();
        }

        if(isGrounded())
        {
            anim.SetBool("isJumping", false);
        }
        else
        {
            anim.SetBool("isJumping", true);
        }
    }```
#

and then i set is jumping false if is grounded

#

why isnt it working?

languid spire
#

well that looks like your if isGrounded code will override the DragEnd code

stone pilot
#

uhhh I dont get it, well if you need the whole script I'll share

tight latch
#

so i have this script which has movement and jump but when the ground check is changed from 0 to say 1 the gravity becomes so slow why is nthat

literally what i only did is change this: (line 22-23)

        playerSpawn = spawnHandler.spawnTransform;```
to this: (line 22) on the start()

``` transform.position = spawnHandler.spawnTransform.position;

and every time i made that change, it just made that one line error. anyone knows why???

weak cedar
#

spawnHandler is null

hallow apex
#

What's at line 35?

jaunty bay
#

rb.velocity = movementInput * moveSpeed; //overall movement

short hazel
#

The exception indeed occurs on line 35:

(at Assets/Scripts/PlayerMovement.cs:35)

jaunty bay
#

yea, and i never touch that line

#

then it made the error

hallow apex
#

What's rb?

short hazel
#

rb did not have a value (it was null). You cannot access .velocity on null, so this error is thrown

jaunty bay
#

this happens other time as well, where i change something at the script, that one line gets problem as well

#

rb = GetComponent<Rigidbody2D>();

#

private Rigidbody2D rb;

short hazel
#

The object this script is attached to does not have a Rigidbody2D on it.

jaunty bay
#

but it does, n thats what im confused at

short hazel
#

Then you have another copy of this script on another object

#

And that's the one throwing

#

Make sure you didn't add it by accident

jaunty bay
#

hmm lemme check\

#

nope, all clear

#

if it were happen, something else wouldve been moving other than my player tho

hallow apex
#

You need to place a breakpoint and load the rb variable

#

This could be fixed with basic debugging

short hazel
#

It's null, there's nothing to load. Either there is another script and you missed it, or you put null yourself in rb at some point

#

GetComponent finds the component on this object. Not the parent, not the children

swift elbow
short hazel
#

If you drag-dropped the Rigidbody from the Inspector, you do not need to use GetComponent in the code.

hallow apex
#

loading a variable is when a debugger captures information about any variable, whether it has an actual reference to memory, or not

short hazel
#

Well we know it's null because they're getting the NRE, not sure of why the debugger would be useful here especially if there's only one place where they assign to rb

#

One place in the code, the field might be serialized and it's the code overwriting it with null

oh sorry

# jaunty bay this is what i meant

Make sure all scripts are saved, clear the Console and play the game again until you get the error. Look at the new line number in the stack trace of the error

jaunty bay
#

and now,

#

it ... works???

#

i just redo all of the things i did multiple times

How do I check static variables in the editor?

short hazel
#

You can't, they're not tied to an instance of the script (which gets created when you attach it to an object)

short hazel
#

They're available from the code, you can Debug.Log() them or inspect their values with the debugger

jaunty bay
#

i want to execute a function every time any scene is loaded. how can i achieve that?

languid spire
#

subscribe to onSceneLoaded

jaunty bay
# 
    {
        SceneManager.sceneLoaded += OnSceneLoaded;
        Debug.Log("SceneLoad subscribed.");
    }

    private void OnDisable()
    {
        SceneManager.sceneLoaded -= OnSceneLoaded;
        Debug.Log("SceneLoad unsubscribed.");
    }

    void OnSceneLoaded(Scene scene, LoadSceneMode mode)
    {
        spawnTransform = FindSpawnLocation(spawnID);   //look for the correct spawnLocation with the corresponding spawnID
        Debug.Log("Current Spawn Location: " + spawnTransform.position);
    }
}
#

did i do anything wrong?

languid spire
#

As long as that code is DDOL it's fine

jaunty bay
#

do i need to execute it on OnEnable() ?

languid spire
#

It wont execute OnSceneLoaded for the current scene, only when you load new scenes

jaunty bay
jaunty bay
#

so im assuming my function isnt executed

languid spire
#

then your setup is wrong
you need a 'loading scene' with this code and it needs to be ddol, then you can load your game scenes

short hazel
#

Yeah currently it does:

  1. Scene is requested to load
  2. Objects in the old scene are destroyed, OnDisable runs and unsubscribes your method from the event
  3. New scene is loaded and the event is raised, without any subscribers to handle it
teal viper
# jaunty bay

It looks like it's unsubscribing immediately, so obviously it wouldn't react to any scene loaded after that.

languid spire
#

which means he completely ignored the DDOL bit

jaunty bay
#

so its my ddol setup for the game manager thats wrong

# 
{
    private void Awake()
    {
        if (FindObjectOfType(typeof(GameManager)) != null)
        {
            Destroy(gameObject);
        }
        DontDestroyOnLoad(gameObject);  
    }
}```

currently is this
languid spire
#

that is insane

short hazel
#

It works

jaunty bay
#

it works?

languid spire
#

what? find yourself and then destroy yourself

jaunty bay
#

i setup GameManager in all the scenes

#

find the ones that isnt this one,

#

(in which i think thats the problem)

#

and deletes it

languid spire
#

that is not what that code does

short hazel
#

"that isn't this one" is missing in your code

jaunty bay
#

okk lemme try smthing

short hazel
#

You'd usually pair that with the singleton pattern, to have a static reference available

I make a transition from the takeOf to the Idle

#

and then I called it when the player is grounded

atomic holly
#

Is there a solution to do an action one time if the condition is true and after still the condition is true, do something else
For example ```c#
if(value1 == value2)
-> value1 += 1; (do this one time)
-> value2 += 2; (do this still the condition is true)

short hazel
#

Sure, keep track of the number of times the condition was satisfied with another variable, and use that in an if statement

# 
if (v1 == v2)
{
  count++;

  if (count == 1)
    // do stuff 1
  else if (count == 2)
    // do stuff 2
}
#

And reset the variable back to 0 when needed

atomic holly
#

I do it with a boolean but it's okay.
I just wanted to know if it was something integrate in the C# or Unity to do something like this

short hazel
#

Nothing that I know of, it's too specific to have it implemented in the base libraries

I have a turned-based combat system and that is how I load in an enemy, as of right now I can only load one enemy, what is the best way to control which enemy I load into the scene each time?

#

One spawns enemies, another one shows it on the hud

lapis frigate
#

so like create an enemy manager?

burnt vapor
#

Yes, pretty much

quaint island
burnt vapor
#

But this is not as relevant. If you want multiple enemies, make more prefabs that represent these enemies. Then you could, for example, set up a dictionary and set them under a key. Then your manager takes this key and it will get the corresponding prefab

#

This is just one way, obviously.

#

But I'd recommend you don't couple your code like you do now, because now it's hard to fix your issue.

#

Or you pass all your data into SetupBattle, but that method should not worry about this

lapis frigate
# burnt vapor Yes, pretty much

and like how do I actualy load the enemies cuz the only way I thought about is to build a method that gets a name and then a very long if list that checks if the enemy need to be loaded by name

burnt vapor
languid spire
burnt vapor
#

Using a list gives the issue of filtering, or knowing their index. A dictionary allows for a known key to be set.

lapis frigate
#

and I should save like all the enemies as prefabs?

#

in the enemies folder?

burnt vapor
#

Well, it kind of depends

#

How complex are they?

lapis frigate
#

now not complex at all but idk if it will stay like that

burnt vapor
#

If they just differ in sprite then you could just keep it simple and specify the sprite name to render in a script

#

But if it has varying behaviour or even more than a single sprite I would probably make separate prefabs and store behaviour in its own script for each enemy

lapis frigate
burnt vapor
#

You can just store the prefabs in a dictionary. If your manager's Awake method is called you could fill it in, for example

lapis frigate
#

but shoud I load them in using instantiate?

burnt vapor
#

Feel free to ping me. Just make sure to not overcomplicate it

burnt vapor
lapis frigate
#

all right thank you for your help

#

wish me luck cuz i will need that lol

burnt vapor
#

Well, remember there are multiple ways of tackling this. Right now I gave a solution that's quite big but scales well, so you can also start simpler if you want

lapis frigate
#

1 more question

#

every time the enemy is loaded its loaded by its name, and cuz of that I cant use GameObject.find is there a solution to that?

quaint island
burnt vapor
#

Instead the manager helps here quite a bit actually

#

You can make your manager a singleton: https://unity.huh.how/references/singletons
What happens is that your manager can now be accessed from anywhere. This works well because you only have one manager to manage your enemies.

#

Anyway, this manager spawns your enemies. What you can do then is when you spawn your enemy, you store the instantiated gameobject in a list in your manager.

languid spire
burnt vapor
#

So now, if you want to find your enemy again, check this list. If you want more control you can once again use a dictionary with custom keys. Alternatively, store them under their "type" in a dictionary, and then it could return all enemies of a given type.

#

You can also try using your Find method, but remember that calling it is slow. Prefer caching its result if possible.

lapis frigate
#

allright

#

I really appriciate it

#

thank you a lot

Are there scripts which are not?

short hazel
# clever idol i dont think its just 1 dupelicate

The errors are caused by the duplicates. It sees that the class is there twice, and it thinks all its members (fields, methods) already exist, so it throws errors everywhere. Removing the duplicate file will fix all the errors.

Open your project in file explorer, navigate to the folder and look for the file.

My man, it's not a code problem. You literally need to use your eyes to spot the duplicate file

#

Surely you could spot a file that doesn't belong if you check in it.

I'm talking about a file, possibly with - Copy suffixed, sitting in the folder

How about you check and then come back

yes

#

i have a turn based combat game and im trying to figure out a way to load a diffrent enemy each time

weak cedar
#

Well you could make a list and have EnemyPrefab1, EnemyPrefab2, EnemyPrefab3 and so on

#

Then load different EnemyPrefabs

cosmic quail
burnt vapor
#

If the variable is private or inaccessible, then you can't change it from code without reflection.

languid spire
lapis frigate
#

I created an enemy manager and created a script for it, should I also add the battleSystem script as a component?

burnt vapor
#

Also, you don't need Resources.Load. If you know the enemies beforehand you can set up a list or dictionary and assign enemy prefabs there that must spawn.

then in the start/awake, appVersion = Application.Version;

you can access appVersion later on

then in Awake/Start, appVersion = Application.version

queen adder

you can make it a property tho

Create a folder called resources and place that prefab in the folder

isn't it a bit impractical when i will have dozens of enemies?

how is what you're doing more practical ?

umm idk I guess if i will have them stored in an enemies folder then I can load them from that folder will be easier?

lapis frigate

so you didnt read again the docs on how to correctly write it ?

even though the page tells you exactly how to write it

if Dwayne.prefab is in the Resources folder

then Resources.Load<GameObject>("Dwayne")

You don't need the ".prefab"

just the "Dwayne"?

Hey Guys! Im struggling with List.Add..
I know how to do it with gameobjects/ strings etc but my list is based of a custom function " dont know if that is the correct term, sorry"
and I dont know how to add it correctly
The setup:

public List<Digit> digitData = new();

    [System.Serializable]
    public class Digit
    {
        public int representingNumber;
        public float rotationAngle;
    }

Where I want to add and set the parameters

   private void AssignDigits()
    {       
        for(int i = 0; i < NumberAmount; i ++)
        {
            digitData[i].representingNumber = i+1;
            digitData[i].rotationAngle = i * rotationAmount;
        }
    }

Right now I set the list size manually in the inspector but that isnt ideal

rich adder
#

unity docs tbh is one of the actual ones that are pretty clear in comparison

lapis frigate
#

ye I get that You helped to much to come at me

#

aka a type

#

.add should work just fine, make sure you are actually creating an instance new() of the item you want to add to list

weak cedar
#

I would recommend the foreach loop

#

Also, you are changing the variables of null elements

#

digitalData[i] does not exist yet because you didn't .add one yet

rich adder
#

they have elements

weak cedar
#

Or you added it somewhere else in your code and I can't see it

rich adder
#

they said it was added in the inspector

#

they are probably struggling creating a new instance of Digit to pass to Add

weak cedar
#

They said they set the size

rich adder
#

that creates elements (populates the list with null items)

#

in the inspector

quick pollen
#

@still wren u managed to solve the out of bounds issue?

rich adder
#

without knowing what OP true issue was with Add without detail, pretty sure the issue is they probably did not know how to do a new instance and add it to the list via code

weak cedar
#

I would create a constructor new Digit(int repNumber, float rotAngle) then digitData.Add(new Digit(i + 1, i * rotationAmount))

weak cedar
quick pollen
#

I think

#

someone correct me if im wrong

rich adder

Thanks for correcting me about the code snippet, and teaching me about the correct term 🙂
and yes that is correct Im struggling to create a new element in the code, I thought that it would have looked something like this but I was wrong

    {       
        for(int i = 0; i < NumberAmount; i ++)
        {
            Digit temp;
            temp.representingNumber = i + 1;
            temp.rotationAngle = i * rotationAmount;
            digitData.Add(temp);
        }
    }
quick pollen
#

this is the image he sent

thats how it works, right?

you can also assign a constructor to it that can take in the data you want as parameters as shown in example above

is there a way to access a variable via a string of the name or id?

public class OtherClass
{
  var variable;
  void GetVar(string id)
  {
    variable = // get variable based on ID
  }
}
#

the best I can think of is to make a function that returns T with a switch case in it but that's not very dynamic

so I wouldn't be able to set it?

#

I can see how u can make a dict for reference types cuz u can pass through the reference, but u can't do that with data types right?

rich adder
neon ivy
#

value type* mb

also u'd have to make a dict for each type, unless u can make a <string,T> dict? that sounds silly

teal viper
languid spire
#

Dictionary<string, object>

neon ivy
#

ooh object

rich adder
#

that or , just make a containing class or struct

rich adder
# neon ivy I can see how u can make a dict for reference types cuz u can pass through the r... 
public Dictionary<string, float> valueTypes = new();
public Dictionary<string, Transform> referenceTypes = new();
private void Awake()
{
  Vector3 position = referenceTypes["someId"].position; //gets copy of pos (v3 is a value type)
    referenceTypes["someId"].name = "Something";//changing the original
    position = new Vector3 (32f,32f,3f); // does not change original pos

    float value = valueTypes["someId"];
    value = 23; //does not change the original, its only a copy

}```
neon ivy
#

the idea is that I made a chat system so I can create commands like in minecraft so I was wondering how I could set up a dynamic way to set variables from the game itself.
so like /SetVar [script reference] [variableID] [value] which would be nice for debugging in a build

rich adder
#

literally a dictionary

#

you can even store functions

neon ivy
#

is a delegate an object? poi_shock

rich adder
#

you're using OOP everything is an object 😛

neon ivy
#

fair xD. so I'd have a <string,object> dict, could I put it in an interface ICommandable so I can gather any ICommandable script in scene? think I remember being able to make value types in interfaces as long as they do the {get;set;} thing

rich adder
#

as long its a property or method it can be there

neon ivy
#

so a dict property? UnityChanHuh the difference between a variable and a property kinda go over my head, they seem like the same thing most of the time to me

if that's the only difference, why can't an interface have fields but it can have properties?

# neon ivy if that's the only difference, why can't an interface have fields but it can hav...

An interface can't contain constants, fields, operators, instance constructors, finalizers, or types. Interface members are automatically public, and they can't include any access modifiers. Members also can't be static.

Interfaces - define behavior for multiple types - C#

An interface in C# contains definitions for a group of related functionalities that a non-abstract class or a struct must implement. It specifies the members and their signatures for a type that implements the interface.

and interfaces can have methods

#

that's my understanding, at least

using TMPro;

public class green : MonoBehaviour
{
    public TextMeshPro tmp;
    public int amountToAdd = 1; 

    private int moneyAmount = 0;  

    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.name.Contains("Circle"))
        {
            if (gameObject.name.Contains("green"))
            {
                Destroy(collision.gameObject);

                moneyAmount += amountToAdd;

                tmp.text = "$: " + moneyAmount;
            }
        }
    }
}
``` the code works but majority of the time when the circle collides with the green it can remove from the money amount ex: money at 3, circle colides with green, money goes down to 1. does any1 know why this happens?

oooooh

#

that actually makes a lot of sense... UnityChanCoder

teal viper
#

Properties are basically a syntactic sugar. In Java you have to use actual methods for that.

#

There's a lot of features like that in C# that the compiler does for you.

I was actually coding a web API for a database a while back in java and I was wondering why I had to make a get and set method for each variable think I guess C# is just very nice xD

henlo, a quick confirmation question

transform.position = spawnHandler.spawnTransform.position;

this will change the current object's position to SpawnHandler's (script) spawnTransform (a Transform) position, correct?

# 
GameObject gameManager = GameObject.Find("GameManager");
spawnHandler = gameManager.GetComponent<SpawnHandler>();```
polar acorn
#

Yes, whenever this line runs, it will set the position of this object to the position of the other

Where's the function identifier/name?

#

It's not that different than C# until you get into templates. I hate templates.

#

And macros

#

Just need to know what the const keyword does in each situation and references/pointers obviously.

cosmic dagger

#

My biggest thing is learning when to use a reference or a pointer since a pointer is a reference but with more power, haha . . .

teal viper
#

I'd say the same as public fields in C#. Avoid at all costs, unless absolutely necessary.

#

Though, maybe that's an exaggeration.

#

Since nullptr can be useful.

#

I guess passing a value type by ref vs using a reference type instead, is a better analogy.

Once I get the control flow down, it'll be more manageable. I will say, refactoring is more complicated. I get lost going from file to file and trying to avoid classes included multiple times from other header files. I have a StateMachine that needs the header from State and vice-versa, so I have to figure that one out . . .

if they use a rigidbody also

deft grail

when i add more mass, i don't jump as high, i want to jump the same height, but i want a higher gravity

deft grail
#

also change gravity and stuff

static wasp
deft grail
# static wasp how

you can do it in project settings i think, not sure if thats the ONLY place or not

static wasp
#

is it in the rigidbody section?

deft grail
#

probably in the docs

slender nymph
#

2d rigidbody has a gravity scale property you can assign to

static wasp
#

thanks

slender nymph
#

what i personally like to do is keep gravity scale around 1 when grounded or performing a jump, then at the apex of the jump (or when pressing down) increase gravity scale so the object falls quicker. you can also compensate for your reduced jump height by simply increasing the amount of force applied

static wasp
#

but, how do i access the gravity scale from a script?

deft grail
# static wasp thanks

theres videos for that on youtube you can find if you want, ive seen it before.
its a pretty common technique

# cosmic dagger honestly, i just want to make a text-based dungeon crawler. move to a room, choo...

a good idea for learning project to do for sure, I did a much simpler text based rpg with one of my first projects in C# console, taught me a lot, esp working with loops something I wasn't comfortable with in the beginning.
And yeah for current project I'm working dealing with hardware and microcontrollers, is to be used in Unity. For this I need such low language, it really makes you appreciate such high level languages like C# at least lol Its good feel though to have such little programs be so efficient and fast.
Eventually the plan is to move onto playing around with more bare metal controllers and C++ seems the next step

I have a problem; I tried using Firebase's real-time database, but it's not supported on Android. Do you have any alternatives you can suggest, or how do you handle databases in your games to ensure it's convenient?

potent olive
#

would anyone happen to know what the hell is going on here? anything labelled "Input" is a textmeshpro text input. theyre all strings, shouldnt they all work?

This happens for both RefreshContainer() and RefreshValues()

RefreshContainer() is called whenever a text input is changed

# signal cosmos auth2 + save load system

Not sure what auth2 is exactly(some kind of authentication system?) and why you need a database for it, but database for saving and loading is probably not a great idea. Are you developing an MMO with thousands of players?

#

Is the save data supposed to be saved on the cloud or locally is fine?

potent olive
#

yeah...that didn't work.

image.png
slender nymph
#

have you considered using the debugger to inspect what the string actually is? or even printing it?

potent olive
#

i didn't think I'd need to, but here it is anyways

image.png
#

also id like to note that the lines for the .name work perfectly fine, but only when the other lines are commented

slender nymph
#

the name property can have whitespace in it. whitespace is, notably, not an integer though

potent olive
#

it does not have whitespace

slender nymph
#

how have you confirmed that

potent olive
#

the input field does not allow it

#

character validation: integer

image.png
slender nymph
#

well then i guess your string is in the correct format for int.Parse! congrats on not having an issue, i guess

potent olive
#

uh, thanks? my issue isn't fixed though-

slender nymph
#

so then what do you think that indicates?

#

because you've printed the strings and see that the only visible characters are integers, and yet it's still not in the correct format for int.Parse

potent olive
#

i'm not sure we're on the same page, the issue isnt just for int.Parse

slender nymph
#

are you still going to try insisting that there is no whitespace in your string?

#

also, yes the issue is just for int.Parse. it's literally what is throwing the exception

#

the code after the int.Parse line cannot run because an exception was encountered

potent olive
#

i'm trying to be polite here. there are two fuctions, both of which fail. One of them does not use int.Parse

slender nymph
#

you have not shown any stack trace that has anything to do with any other method

potent olive
slender nymph
#

holy shit dude, did you even look at the most recent part of the stack trace?

#

your issue is literally still int.Parse because you are modifying the text object which invokes the event which invokes the method that invokes int.Parse

potent olive
#

also note that when this screenshot was taken, RefreshContainer() was NOT being called and the Parse lines were commented out anyways.

image.png
slender nymph
#

can you read?

potent olive
#

however it's still not explained, since again, the parse lines are commented out.

slender nymph
#

i will ask once more, can you read?

potent olive
#

oh wait

#

whoops

#

nevermind, that's entirely my fault 😅

slender nymph
#

yeah so anyway, the issue is whitespace in the string

#

that Trim call you have only trims that one whitespace character (which is sadly not trimmed with the default Trim() call)

mighty marsh
#

its my first time using raycast and I'm trying to use a layermask to trigger a function when im looking at a specific function, but it seems to trigger anyways no matter what object i'm looking at or what layer its on

slender nymph
#

show code

mighty marsh
# 
    

    // Update is called once per frame
    void Update()
    {
       Ray ray = new Ray(transform.position, transform.forward);
       
        if(Physics.Raycast(ray, raycastLayer))
        {
            turnOnLights();
        }
    }```
#

specific object*

slender nymph
#

you've actually just provided a maxDistance because the first optional parameter for Physics.Raycast that accepts a Ray as the first parameter is the float distance. LayerMask has an implicit cast to int which also has an implicit cast to float
https://docs.unity3d.com/ScriptReference/Physics.Raycast.html
You need to either provide a maxDistance before the raycastLayer parameter, or use Named Arguments

mighty marsh
#

if(Physics.Raycast(ray, maxDistance: 100, raycastLayer)) like this?

slender nymph
#

well if you do that you don't need the named argument

#

but also if you do use the named argument there, you'll need to do so for the layerMask argument as well

mighty marsh
#

it still wasnt working but it was actually an issue with the mesh collider

#

thanks for the help

tawdry trench

does anyone know how to have a game object reference another object by name only under its group? So for example, it searches for attackpoint1 under player but not outside of it.

image.png
slender nymph
#

Ideally you would get a direct reference to the object instead of trying to find by name. but have you looked at the docs for GameObject.Find or even Transform.Find?

tawdry trench
#

I was using gameObject.Find but when i use that, it also searches stuff outside of the group.

slender nymph
#

i'm guessing that's a "no" on the question about looking at the docs for that method then

tawdry trench

yeah no i haven't

#

also the hyperlink leads to a page that doesn't exist

does setting position to an empty gameobject each frame is the same as set parent transform?

to limit the line renderer you would need to raycast each point in the points array as you are building it. To add a gameobject, simply position it at the last point in the points array

instead i have to mess with selecttokens which is so unintuitive

Now you have a reason to write your own Json library

im already using this custom one because unity one is even worse

where i need to specifically write down classes for it

languid spire

Nothing beats rolling your own if it's specific functionality you want

my own one looked pretty much string.split("key")

was nice to use but definelly not performant

actually Nettonsoft is open source so just grab a copy and mod it

but what to mod

#

dont tell me you cant just grab by specifying path you could do when writing to it

languid spire
#

I don't know, I don't use it, I have my own Json library (lol)

And I certainly can do what you suggested
