[radiant frigate]

well + whatever i need it to debug :

imma read the docs maybe i can figure it out alone now with the tips you gave me

ty both!

[carmine turret]

Any ideas on how I could fix this? or amI going to have to program my way around it 😛

Actually someone suggested changing this, oes anyone know what it does?

Okay nevermind I learnt what it does, but It doesnt seem to help.

[buoyant knot]

the point of iterations is to give the physics system the ability to refine the result of a simulation

[carmine turret]

Yup, got that

[radiant frigate]

okay i have made an advance

[carmine turret]

Sadly it doesnt seem to fix my issue

[buoyant knot]

think of a simulation like trying to solve a math problem approximately. More iterations lets you put more effort into the solving, which makes it more accurate. But should not fix a problem

if it does fix a problem, then you were really truly fucked

[carmine turret]

maybe if I crank it really high, but Of course I dont really want to do that becuase of performance

[radiant frigate]

i noticed it actually shoots, but somehow it doenst gives a velocity to the bullet , it rotates it just fine but somehow the velocity does not work

[carmine turret]

Hrm... Not sure how I can go about fixing this honestly

[buoyant knot]

is your player’s rigidbody collision mode set to continuous or discrete?

[carmine turret]

Ah.

Discrete

assuming thats PROBABLY it

[buoyant knot]

yeah. that’s very wrong

[radiant frigate]

OH and this all happens because the bullet actually searches with a tag instead of with getcomponent.

[buoyant knot]

change it

[radiant frigate]

or atleast thats what i think, but i dont know how that would interact with the way the bullet assigns the velocity

[carmine turret]

Yuup all fixed! Thank you

Honestly, Think im basically done with my entire controller!

[radiant frigate]

here is the part of the code that should be affected by the bug.

[buoyant knot]

if your collision detection mode is set to discrete, you check collision at specific points, instead of like a continuous line. Which means you land inside walls and blocks and shit, instead of going up to them

[carmine turret]

Gotcha

Worse for performance I assume

but for one character I imagine its negligible

[buoyant knot]

sure. i remember i had the exact same problem, until someone else told me the same solution

[carmine turret]

hahaha

[buoyant knot]

oral tradition

[carmine turret]

The control feels super good to use

Some really decent platforming I think. now I guess... art and levels + level mechanics

eesh this is gonna be "fun"

[buoyant knot]

“fun” is code for garbage

[carmine turret]

My artistic skills are lacking

I could maybe buy some art assets but ehhh I dunno

then if I do still need to make some assets, the style wont match

[buoyant knot]

make it work before you touch art

[carmine turret]

same with the character I guess

[carmine turret]

Oh its fully working!

Ive had some people playtesting too ^^

[radiant frigate]

if you are not going to sell it or use it in a game jam and are just learning i dont see having fancy sprites as a must, but it can make the game feel fresh

[carmine turret]

I wish to potentially sell the game as my first indie game

I rewrote the entire code to be cleaner for future stuff just incase

[radiant frigate]

i could also playtest if you want

[carmine turret]

Thatway if I make map mechanics that require controller edits, then I can come back and do so easily

Appreciate it, but the test map I have isnt really suitable for it and I am shattered. 2 hours sleep in 48 hours is taking a toll hahaha

[buoyant knot]

Your game should be good without fancy art, and then you add art to enhance.

[carmine turret]

Of course

but I need art to build the map

[buoyant knot]

so don’t stress over art

you don’t need the mona lisa

[carmine turret]

its a grappling hook based height platformer

I could just grey boy everything for now

and make a bunch of grey assets and replace them with proper sprites later

[silk night]

If you are like me and need some eye candy while developing, even if the style is mismatching use free asset packs first, and replace them with a consistent style later

that way you can block out your level but it doesnt look like a grey-block desert

[radiant frigate]

loup can i ask for help in one thing, do you have a high knowledge on how references work ?

[buoyant knot]

i know the basics

[radiant frigate]

surely with that it will be enough i think

okay lemme give you full context

[buoyant knot]

and FindGameObjectByTag is a noob trap

[radiant frigate]

yeah i think that is what happend to me

[buoyant knot]

because it has to search the whole scene for the reference

[carmine turret]

Those assets might not match the items I need so I think Ill just greybox everything and put a background on to make it easier to see everything

Then come back and make new assets matching the shapes I used before

[buoyant knot]

and also it would need to be unique

[radiant frigate]

yeah i have a prefab with that tag so i think thats where it all goes wrong

[carmine turret]

So ill prolly make like 20 or so different shapes for the platformers themselves + interactable objects, then come back and remake them in each map flavour

[buoyant knot]

if you have a fixed object in your scene, then use SerializedField

[radiant frigate]

let me give you a video so you can see what happens

[carmine turret]

(9 realms, so 9 different flavours some of which will be very similar)

[buoyant knot]

yeah, that’s very wrong

[radiant frigate]

its not fixed ( if fixed means what i think it does) it is a prefab that spawns randomly from a pool

[buoyant knot]

are both of the referenced scripts in the prefab

[radiant frigate]

nope

in is in the bullet that the first prefabed " pink enemy" instantiates

[buoyant knot]

does the object in the scene need a reference to the script in the prefab, or the other way around

[radiant frigate]

the bullet needs to know which bullet number she is so she can have certain rb2d.velocity

[buoyant knot]

so the script in the prefab needs to get information from the other object

[radiant frigate]

and im thinking that somehow has a conflict with the other thing shooting

[radiant frigate]

yep

isnt there a way to instantiate it ( the bullet) as a child and get the information of the father (pink enemy)

[buoyant knot]

so you need to:

1. When you Instantiate, keep reference to the object you made
2. GetComponent on the thing you made, to search for a specific script.
3. The script you find needs to have a public method in it so you can pass the necessary information in it

Instantiate returns a ref to the object made

[radiant frigate]

it will seem like im just telling you the same that you did but i wanna see if i understood:
1st: when the bullet gets instantiated i need to keep a reference to the object that instantiated it
2nd: GetComponent on the bullet that searches for a script in the referenced gameobject previously mentioned
3rd: the script i find with the GetComponent needs to have the variable public

[radiant frigate]

how?

[buoyant knot]

the return type of Instantiate is GameObject

[radiant frigate]

i havent really understood return completely

what i understood is that it returns a variable to something

but i dont know how to tell which one to whom it should be returning to

[buoyant knot]

https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

[buoyant knot]

then you need to learn how return types work

it is a fundamental part of the language

[radiant frigate]

alright !

but b4 going to read the docs

i think the problem is the previously mentioned

but how can it affect in that way

wouldnt the bullet just get instantiated in the same way that the ones from the other pink enemy do but just from the position of the new pink enemy ?

[buoyant knot]

whenever you instantiate, you want to:

1. Instantiate
2. SetParent for the transform to the new parent gameobject
3. Set the position

[radiant frigate]

yes i know thats what i want to do

but the thing that is missing is not that it doesnt spawn

its just that it doesnt take a velocity

[buoyant knot]

you need a reference to it to be able to tell it to be modified

[radiant frigate]

and why does it work in the first pink enemy?

[buoyant knot]

because you are probably getting a reference to the same one enemy when you FindGameObjectByTag

which is a function you should realistically not use

[radiant frigate]

i dont understand it but i guess once i read the docs maybe it becomes clearer to me

ty for the help!

is it this what i want to do?

btw whenever i ask something its more like giving my pov or what i think is correct and questioning it

not like: idk if this is it but it may be so imma just ask

[timber parcel]

I've been trying to include the class of this script into another script to access it's variables by doing this

Public PlayerCombat playerCombat;
public int damage = 1;

Public void Damage Player()
{
playerHealth = playerHealth - damage
}

playerHealth is the currenthealth (sorry if its a bit confusing)

problem is, when I do it, the variable isn't recognized in the other script

I'm gonna try to replicate it again since I deleted it all yesterday

[eager plinth]

does anyone know where I go to fix this error? like what pannel?

[timber parcel]

Have you tried restarting?

[eager plinth]

twice.

[timber parcel]

yikes

[rancid tinsel]

is there a way to check if an object is attached to a canvas in script?

[eternal needle]

what would you need to do this for?

[timber parcel]

maybe something along "isChildOf" perhaps?

aw

[rancid tinsel]

im setting up a cursor manually as a UI component, but i need to take it between scenes

[timber parcel]

Oh also I'm also looking for some help too.. we can talk here but DMs might be nicer

[dawn kestrel]

I'm trying to check on a specific layer if a particular region of space has any colliders. Google keeps leading me to methods like BoxCast and CheckBox, but they seem to have far too many arguments for what I'm looking for. How do I add something akin to a Collider to an object such that I can just get that attached collider-like-object to basically do a CheckBox by calling an argumentless method?

[eternal needle]

what part of this requires you to know if its under a canvas? this is something you do at editor time, so if you put it under a canvas then it is under one

[rancid tinsel]

moving it between scenes is at runtime though

do you mean to put 2 separate objects in 2 scenes

in charge of the cursor?

[eternal needle]

you can just move the canvas, but also this might be something you wanna put in DDOL

[eternal needle]

your closest option would be using a trigger collider, then keeping track of what enters through OnTriggerEnter and OnTriggerExit. Or just learn how to use any of the overlap functions https://docs.unity3d.com/ScriptReference/Physics.OverlapBox.html there are examples

[dawn kestrel]

is there a component that can call Physics.OverlapBox using public variables already set on the component?

[eternal needle]

a component? just call Physics.OverlapBox with the public variables that you want. it really isnt that complicated to use any of the physics methods and the docs i linked does show you an example. it even shows you with OnDrawGizmos where this box is

if you have a question about how to use it, then thats better to ask rather than trying to find an alternative

[dawn kestrel]

do I just make a new behaviour script?

[queen adder]

Anyone know why a camera mode canvas rendering to a rendertexture displayed in a raw image doesn’t look exactly like what it shoud

[radiant frigate]

i did it!

[queen adder]

Above is the tmp text in the raw image, then theres the exact same tmptext but on a screen overlay canvas. i tried messing with the import settings, color format etc. to no avail

it looks like maybe its not supporting transparency correctly? which format would be correct:/

[summer stump]

If you want to 🤷‍♂️

It's not needed though

[dawn kestrel]

Is there a way to pull all the information needed for the cast from the object?

or rather, a component on the object?

[teal viper]

First figure out if the problem is with the render texture or the camera that renders to it.

[summer stump]

I'm not sure what you're asking

the link above shows what you need with example code and everything

[eternal needle]

you may be overthinking this. this is just a simple method call, you provide it literally any information you want. the same way you call stuff like AddForce

[dawn kestrel]

haven't used that yet

[summer stump]

It's a method. It's the same way you use ANY method

[eternal needle]

you might wanna do some basic c# lessons first then, if you arent sure about how to call a method

[dawn kestrel]

Here's an example of my code so far. I misunderstood a page that showed BoxCast listed under a heading of Methods under a heading of CapsuleCollider, and got a little too hopeful.

admittedly this is me modifying a far more complicated scene.

[eternal needle]

are you modding a game by chance?

[teal viper]

Seems to be something from VR chat.

[dawn kestrel]

a VRChat world, though really more of a system someone set up for making certain kinds of worlds

[eternal needle]

oh i didnt see the last message, yea u should be asking for help in the games modding community instead

[dawn kestrel]

they're not particularly active right now.

Though, the reason I asked about making it a new script is because each zone being checked will be tied to an area, thus for that particular object, I want the variables stored with it.

the jist of what I'm trying to do is check to see if an object on the Walkthrough layer is on the runway I have here.

since there will be multiple runways, the thing that makes sense for me is to have each runway have its own "checker" to see if the runway is clear, returning a bool to another object on its status when asked.

though more and more, it looks like a premade solution doesn't already exist (unless there was some way to use CapsuleCollider.OnTriggerStay like some sort of pseudo-bool)

[rancid tinsel]

https://gdl.space/efarezesat.cs - CursorScript, https://gdl.space/jecisikimi.cs - SceneManager. Any idea why the CursorScript object is getting destroyed when changing scenes?

[queen adder]

How would i go about doing that? I played with all the settings. RT dimensions is the same as game window size.

[teal viper]

Either look at the camera preview window or make it a main camera temporarily to see how it renders to the screen.

[queen adder]

seems like for some reason the render texture has this blueish gray outline instead of additive alpha. which is weird, because i dont know what could be saturating it 🤔

[rancid tinsel]

I just tried setting it as a child of the SceneManager gameobject and it still gets destroyed

[queen adder]

i see ill try that, would help me narrow down if its a rendertexture/rawimage issue or not

[summer stump]

A DDOL object must be the root

You are setting it to be the child of an object
this.transform.SetParent(FindAnyObjectByType<Canvas>().transform);
So the canvas is likely being destroyed (assuming THAT is NOT in DDOL), which of course destroys its children

[rancid tinsel]

before scene change I was setting it's parent to null

[summer stump]

Ok, verify that is actually happening when you think it is with a debug.
Add a OnDestroy() method to the CursorScript and just log when it happens and its parent if it has one

[polar acorn]

Send a screenshot of your unity window with the cursorscript object selected, right before changing scenes

[rancid tinsel]

scenes change when I hit play

[summer stump]

Hmm, that is not in DDOL

[polar acorn]

Cursor is not a DDOL object. It has a parent at the time you make it a DDOL

[rancid tinsel]

it returned "Canvas"

[polar acorn]

Only top-level objects can be made DDOLs

[summer stump]

So, when you parent it, it moves OUT of DDOL

[rancid tinsel]

oh should I set it to DDOL when making it the root

[summer stump]

Yes

[summer stump]

And that means when it is destroyed, the canvas was still the parent I guess

[rancid tinsel]

btw is this the correct syntax for making it the root

[timber parcel]

Hey I need some assistance

[rancid tinsel]

i feel like i might be just doing some crazy stuff rn cuz ive never done this before

[summer stump]

no need to do gameObject.transform

just go straight to transform

And do DontDestroyOnLoad(cursorScript.gameObject);

[rancid tinsel]

will this not work?

[summer stump]

Ah, ok yea. It isn't necessary, but it will

also, you don't need the "this" anywhere like that

[polar acorn]

https://dontasktoask.com/

[rancid tinsel]

ill try your method because its way cleaner lol

[summer stump]

gameObject already means that object the script is attached to

[timber parcel]

Im waiting to see if anyones available

I asked a few moments ago

[summer stump]

Don't do that. Just ask. If it got buried, repost

[polar acorn]

Actually, a question: Why is CursorScript a DDOL? It's not a singleton, and it doesn't seem to have anything particularly important you need to carry across scenes

[rancid tinsel]

i just thought it might be better than having one in each scene

[polar acorn]

why

[timber parcel]

alr

[rancid tinsel]

tbh idk ive been coding for the past 18 hours

[polar acorn]

You've had to do so much parent shuffling and DDOLing instead of just like, having one in each scene

Do that and you basically cut out 80% of the code that's here

[rancid tinsel]

true

[timber parcel]

Im trying to get public variables from this script (related lines of code highlighted)

And here's the attempt

[rich adder]

!code

[timber parcel]

I'm not really sure what I might be missing here, my other codes are following the same thing

[polar acorn]

No they aren't. You don't have a reference here

You're trying to use a variable on Enemy that doesn't exist

[summer stump]

Your other codes cannot be doing that without an error

[polar acorn]

If you want to use a variable on an instance of PlayerCombat you have to tell it which PlayerCombat you want to reference

[summer stump]

https://unity.huh.how/references

myPlayerCombatReference.playerHealth

[timber parcel]

Okay.. a bit lost here

[summer stump]

you need a variable that holds a reference to the specific Player Combat component you want to get the playerHealth value from. Then you access playerHealth through that reference using dot notation

[polar acorn]

Which PlayerCombat do you want to access playerHealth of

[timber parcel]

there is only 1 playerCombat script

[summer stump]

irrelevant

[polar acorn]

Your code doesn't know that

[teal viper]

The game engine/ compiler doesn't know that

[summer stump]

You could decide to make more at any point

[timber parcel]

How exactly do I specify which one?

[summer stump]

#💻┃code-beginner message

[polar acorn]

There are many doors, Ed-Boy
#💻┃code-beginner message

[summer stump]

If you can, you want a serialized reference

Otherwise, you are likely instantiating something, and Instantiate returns the object instance that was instantiated, so you just pass that where it's needed

[radiant frigate]

is there smth that manages probability in Random.Range, for example: Random.Range(1f(10%), 2f(90%));

its something hard to explain so idk how to google it if it exists

[summer stump]

Not that I know of, you could perhaps finagle the animation curve into doing something like that?
Find some random position on the curve

[summer stump]

The term you're looking for is weighted random

[radiant frigate]

finagle?

what is that

[radiant frigate]

okay i will check into that

b4 all

[summer stump]

Doesn't matter, just meant it as in fiddle with it

[radiant frigate]

does it work is the range is larger than 2 ?

[radiant frigate]

ohhhhh

[summer stump]

but looking up the definition, the word doesn't really fit there

[radiant frigate]

didnt understand the word

[polar acorn]

Random value between 0 and 1. If it's over 0.9, return 2. Else, return 1

[radiant frigate]

wouldnt that make the code chunky once you have like 10 options?

[polar acorn]

Switch statement

[radiant frigate]

true

my mind wanted to use that but went to a mix between that and ifs

i can just use switch and it would work

[radiant frigate]

ty for the idea!

i think it wont work tho because on what i want to implement it

but i will try b4 making assumptions since it works strange and i need to sit there and think how i want to make that

[summer stump]

Just found a post describing a way to do it with the animation curve just how I was thinking, but explained better
https://forum.unity.com/threads/making-random-range-generate-a-value-with-probability.336374/#post-2179247

[radiant frigate]

i will check that first then

ty!

[timber parcel]

So
public PlayerCombat playerCombat;
(the reference to PlayerCombat and its playerHealth variable) isn't going to do that?

[summer stump]

No

that is a declaration

you need to actually populate that variable with the reference

[timber parcel]

So in unity's case... drag and drop it into the box in inspector?

[summer stump]

You could drag the PlayerCombat script (that is attached to an object) into the field via the inspector

Yes, exactly

[dawn kestrel]

is there a quick and dirty way I could use a CapsuleCollider to pull parameters for a Physics.CheckCapsule?

[timber parcel]

Ok but here's the strange part, even though it's public, it doesn't appear in my inspector

the script is saved I assure

[summer stump]

Is PlayerCombat a monobehaviour, or serialized?

[timber parcel]

monobehavior

[summer stump]

(I think you showed it, but I can't remember)

[summer stump]

Ok, hmm. Can you show the inspector and code?

[shut spade]

quick question, how many does FindGameObjectsWithTag consume in the game?

[summer stump]

I don't know what that means

[summer stump]

How many what?

[timber parcel]

sure, also which code? the enemy or PlayerCombat

[shut spade]

using it for an ai

for ramming targets

[summer stump]

I'm not sure, I guess lets just do the inspector for now

[summer stump]

How many what?

[shut spade]

performance

[summer stump]

Oh, how efficient is it? Not very

Avoid Find whenever possible

[radiant frigate]

i reached to the same conclusion as the guy, since i only want this probability thing for 1 part of the game i will just hard code through it because it would take me less than to set up a whole data struct

[shut spade]

any better solution?

[summer stump]

https://unity.huh.how/references

almost every other solution is better

Serialized Reference is best

[shut spade]

oke

ill try that

tysm

[timber parcel]

here ya go

[summer stump]

Ok weird. Nothing wrong looking there. Show the Player Combat script?

[dawn kestrel]

I have a CapsuleCollider on a gameObject. I want to pull certain variables from the CapsuleCollider, then use those variables to calculate the Start Point, End Point, Radius, and Layer Mask of a Physics.CheckCapsule() call.

[summer stump]

I mean sure, then do that?

You can't get the layermask from it of course

[dawn kestrel]

wait, really?

[summer stump]

Really what?

[timber parcel]

shoot, too large to but into the discord

[dawn kestrel]

CapsuleCollider has Layer Overrides. I thought I'd be able to pull those.

[summer stump]

Just screenshot the top portion of it

[summer stump]

Just make a LayerMask variable.

what would you even pull from the CapsuleCollider for layermask

that doesn't really make sense

[timber parcel]

using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;

public class Enemy : MonoBehaviour
{

    //hp
    public int maxHealth = 3;
    private int currHealth;

    public Animator animator;

    public bool enemyAlive = true;


    //fighting player
    public int damage;
    public PlayerCombat playerCombat;

    // Start is called before the first frame update
    void Start()
--rest of the script

[summer stump]

And THIS is saved for sure?

[timber parcel]

yep, there's no * on any of the script headers (unsaved)

[summer stump]

The only other thing I can think is that there are compiler errors?

[timber parcel]

and I double checked by saving even those

[dawn kestrel]

what doesn't make sense? All the information I need for where the CheckCapsule will happen would be on the CapsuleCollider.

[summer stump]

Getting a layermask value from it. That doesn't make sense

Just MAKE the LayerMask variable and set it

[dawn kestrel]

set it off what?

[summer stump]

I mean, you can just make variables for EVERY part of this, so I'm not sure what the fixation with the capsule collider is

[summer stump]

Off what you want it to mask. It's a choice. You use the inspector to make that choice

what does that even mean?

[dawn kestrel]

okay then, should I make a script that stores all the variables for a CheckCapsule on the object itself?

[summer stump]

Sure? You obviously need SOME script

I thought you had one already, since you are calling a method.... which needs to be done in a script
I would save the variables in that place

[dawn kestrel]

well, yes, but that's a different object, one that's gonna have to call a bunch of different areas

[radiant frigate]

why is this happening? it says i cant convert int to string but the guy uses it and works just fine

[timber parcel]

OK WEIRD! it finally works now, someone told me to replace

private void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.tag == "Player" && enemyAlive)
        {
            playerHealth.Takedamage(damage);
        }
    }

with

    {
        if (collision.gameObject.tag == "Player" && enemyAlive)
        {
            collision.gameObject.GetComponent<PlayerCombat>().TakeDamage(damage);
        }
    }

Im not too sure what he did there though..

but the damage amount can finally be changed in the inspector

[summer stump]

That is psuedocode on the left
Make it an int[]

[summer stump]

Nice ok, not sure either

[dawn kestrel]

should I be changing my workflow? Right now my logic is that the actual script that does things is on the panel/button that the player interacts with, and the variables for the object being affected remotely are on the object itself.

[radiant frigate]

btw the [] means like a container right?

[summer stump]

no, I mean, they had string[]
replace that with int[]

As the type

[radiant frigate]

yes ik

[summer stump]

Oh ok. The [] means array

[radiant frigate]

but the [] in both means like a list/array

[summer stump]

so, an array of ints, instead of an array of strings

[summer stump]

array, not list. Yes

[radiant frigate]

never list?

because its fixated ?

[summer stump]

[] just means array

[rich adder]

arrays are fixed length

list are not

[summer stump]

List<int> is list

[radiant frigate]

thats what i mean

[summer stump]

It's just how the syntax works

[radiant frigate]

yeah yeah i readed that yesterday or so

lists and arrays are so usefull

[summer stump]

And yes, arrays are fixed length. Lists have an array internally and methods to resize it and make sure the indexes have no gaps

[dawn kestrel]

hmm, so my next question is: if I store the variables I need on the object, is there a way I can use those variables to draw a gizmo?

[radiant frigate]

by methods you mean .add and .remove

[summer stump]

Yeah exactly. And more stuff

[radiant frigate]

yeah yeah i just meant like that type of thing

ty!

[summer stump]

List is a class
https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1?view=net-8.0
This shows a lot about it

[summer stump]

No problem!

[radiant frigate]

i watched a video in depth of that they are pretty cool and can save a lot of time

[summer stump]

C# is turing complete. You can do literally anything. But yes of course you can use values to make gizmos
It's a bit ambiguous the way you're asking though. So I'm not sure exactly what you mean

[dawn kestrel]

I mean so that I can actually see in the unity editor what the area where the CheckCapsule is defined would be.

[radiant frigate]

a question about lists, if i write .remove (whatever i want to remove) it doesnt remove all of the items that match that description, is there a way of doing that?

for example a list that has (1, 1, 1, 2, 2)

is there a way to remove all 2?

[summer stump]

There is a RemoveAll method https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.removeall?view=net-8.0#system-collections-generic-list-1-removeall(system-predicate((-0)))

[radiant frigate]

i have been thinking of maybe a while loop

ty!

[ruby python]

Mornin' all.

I have a ship flying over the moon at a fixed height, conforming to the sphere. On the moon I have some objects placed based on long/lat coordinates and based on images etc. they're accurate, so this is good.

Now what I'm trying to do is get the ships 'live' long/lat position but I'm not entirely sure how to do this. (currently was playing around with an empty at the center of the planet always 'looking at' the ship, but obviously this has problems when crossing the poles etc.

Would anyone be able to point me in the right direction on how to achieve this (a resource etc?) Thanks.

[queen yoke]

private and public i understand

but what about variable without both of them?

[eternal needle]

it is private by default

[queen yoke]

int vs private int = private both?

[eternal needle]

yes

[queen yoke]

ah! i seee

so when we use int
when we use private int?

[summer stump]

When you feel like it

I generally always write private. Some people don't. It's just a personal choice

Just keep it consistent at least

[queen yoke]

lol ah! i see Thank you for both of your answer

for the private variable so can i use the same variable name in diffenct script because it's private saparate from each other?

[rich adder]

you could name it the same name even if public in different classes

[queen yoke]

can i change "other" in red circle to specific gameobject? i'd like to make a ball only to hit trigger

i mean other object which is not "ball" do not affect to this trigger

[ruby python]

You can tell it to check the tag of the collider, if the collider other's tag == ball's tag, execute your existing isKickBallAttack

[north kiln]

https://docs.unity3d.com/Manual/LayerBasedCollision.html
Or better yet only let it collide with that layer

[ruby python]

That too 😉

[queen yoke]

thank you let me try

Hi, I hope I can get some help.

I have a question and have been tryin to understand this for awhile. I have my input system on a separate script and a character controller script to control the 2D gameObject which is my character. I don't know how to implement a sprint button so that when I hold it down, the movement speed changes.

In my Input script, I have a public void for Submitpressed and the function of if pressed true context.start and if not , canceled.

In my charactercontroller script, my movement section is the attached image. (I'm new to this so I followed someone else's tutorial)

When I pressed the sprint key, it only jerks forward and goes back to the normal walkspeed. Is there a code that I needed to implement to make sure when the sprint button is held down, the sprintspeed continues to hold until released? I look through a couple of other videos online to implement but can't stitch anything together that works.

InputScript: https://paste.ofcode.org/z2arnEyGpTTJTQGKK4nGQi
CharacterCode: https://paste.ofcode.org/qszfNXLgwh7e28wDag9zPn

Sorry, I just updated. Is that ok?

[keen dew]

public bool GetSprintPressed()
{
    bool result = sprintPressed;
    sprintPressed = false;

this sets sprintPressed to false the first time you read the value

[vagrant bramble]

I set it to false because I assumed it should be false when the game starts so only when I pressed it, it will be true. When I set it to true, the default move speed for the player just becomes the sprinting speed.

Is there another way I should have implemented this?

[keen dew]

...why would that affect it when the game starts?

Are you mixing it up with private bool sprintPressed = false;

And obviously you shouldn't set it to true there. Just remove that line.

[vagrant bramble]

Sorry, I thought you were saying the line on 146 for InputManager.cs

[keen dew]

Yes, that's what I'm talking about

[vagrant bramble]

Oh gosh. that worked.

[keen dew]

You set the sprintPressed to false every time you check if the player is sprinting. So of course it will be false after that.

[vagrant bramble]

Ok, I kind of understand now. Thanks!

And if I want to add Animation to it, do I just add a line under the button pressed for move and run as well and linked that to the animation?

[keen dew]

The difference between sprinting and the other actions like jumping is that for those other actions you don't want the action to trigger every frame while the player is holding the button so that's why you set the variable to false for them, so that it only registers for the first frame

[vagrant bramble]

Thanks for your explanation, I understand now.

[keen dew]

Yes, in the player controller set the animation based on what the sprint status is

[vagrant bramble]

ok I'll try to figure this portion out

[dawn kestrel]

alright, so I ended up making a function that I think converts a capsule collider into the parameters needed for a CheckCapsule, but for some reason it keeps returning True, and I'm not sure how to troubleshoot.

[rancid tinsel]

any way to run OnPointerUp only if the mouse is still over the object that OnPointerDown was called on? I want the player to be able to drag the mouse off if they changed their mind and are still holding the left mouse button

What this causes is that the color changes, the player can drag the mouse off but the second they let go, no matter where their mouse now is, OnPointerUp is called

[rich adder]

#💻┃code-beginner message

[rancid tinsel]

I'm just giving an example of what the issue I'm experiencing is, I know that code is wrong, I'm wondering if there is a different way of doing it

[native seal]

https://gdl.space/volopocutu.cs can anyone help me with this issue im having? somehow in the SetEnemyDifficulty function, the enemy.BaseStats which is on a scriptable object is getting changed even though im using a copy contructor

[rich adder]

debug what eventData is on if its being called ur mouse is over an object in that hierarchy

[rich adder]

what is Stats

[native seal]

a dictionary

that holds a enum and a class representing 2 floats, max and current

[rancid tinsel]

seems like OnPointerUp takes "Press Raycast" whereas OnPointerDown takes "Current Raycast"

not sure what those are entirely

[native seal]

https://gdl.space/eveqodeseg.cpp

[rich adder]

which one is the SO

[native seal]

EnemyData

EnemyData has Stats on it

[rich adder]

you're changing stats on the same object then

[native seal]

wdym

[thorn tapir]

What would be the "correct" way to implement crouching with the CharacterController? Modifying the controller height will make the player clip through the ground when the collider instantly expands (when uncrouching), but trying to LERP the height or do some wacky stuff with lerping player location while crouching and uncrouching feels really unprofessional/messy and causes tons of issues on slopes. Is there a better method that I'm not finding online?

[rich adder]

to me it seems you're making a copy of the same object and setting the values on the same thing

[native seal]

i have two seperate stats, one on the base "Entity" which my enemy inherits from and then one on the EnemyData SO

enemy is just a monobehavior

i define my enemies base stats on the SO then copy it over to the monobehavior and increase it depending on the difficulty

i don't understand how my SO is getting changed

[rich adder]

well if you're changing a reference type you're changingthe same object

[native seal]

but I used a copy constructor to create a new stats from the baseStats

does that not work?

[rich adder]

you prob made shallow copy or whatever is called

[wintry quarry]

You modify height and center simultaneously to avoid going through the ground (and ceiling)

[native seal]

well look at my copy constructor, is that a shallow copy?

[rich adder]

you mean this cs public Stats(Stats stats) { foreach (Stat stat in stats.Keys) { Add(stat, stats[stat]); } } ?

[native seal]

yes

[rich adder]

those are reference types

[native seal]

ahhh

i see

forgot my value is a class

i changed that recently

[thorn tapir]

why modify the center? Wouldn't leaving it at the bottom and just having the character scale from that point make it smoother?

It just seems like a janky solution even if it's industry standard

[native seal]

this should work now yes? public Stats(Stats stats) { foreach (Stat stat in stats.Keys) { Add(stat, new StatValue(stats[stat])); } }

[rich adder]

if its just stats make struct ?

[wintry quarry]

To keep the bottom exactly where you want it

[summer stump]

The center is not at the bottom. It's at the center..
If you don't move it then shrinking will make the model and collider float
When you say the bottom, I think you mean a pivot? That isn't what praetor is talking about

[rich adder]

what is Stat ?

[native seal]

an Enum

[native seal]

also I need my StatValue to be a class since I change it in realtime

[thorn tapir]

you can move the pivot (called the 'center' in the inspector for the charactercontroller for some reason) so I moved it to the bottom of the character just so it would scale from that point, thinking it would solve my issues.

alas it did not

[wintry quarry]

Scaling is a bad idea

Changing the height and center is the way

[native seal]

basically when i pass my stats into a function, only a copy of the struct is passed

so I would have to make a new struct and assign it

just makes it more annoying

[dawn kestrel]

can anyone give me some advice on how to troubleshoot some code? I can't figure out how to check where it's going wrong.
https://hatebin.com/onsgobcdyq

[rancid tinsel]

am i correct in thinking this will check the OnPointerDown position against the current position of the pointer?

[thorn tapir]

sorry, I meant changing the height. Not the actual scale of the charactercontroller. When adjusting the height it still uses the pivot point.

[wintry quarry]

Use standard debugging techniques. Debug.Log and attaching the debugger

[rich adder]

well yeah but now you have the reference issue where you're modifying the same ref lol

[wintry quarry]

Height always grows in both directions from the center of the CC

[native seal]

well that issue only arose since my copy constructor was wrong

[wintry quarry]

If you moved the center down, when you increase the height of will put the bottom underground

[rich bluff]

is it your code?

[rancid tinsel]

yes

[rich bluff]

purpose?

[native seal]

my Stats used to be a dictionary with Stat, float

but i changed it to StatValue which holds a max and current

forgot I had to change the copy constructor

[rancid tinsel]

I want the player to be able to click on an object to place down a tower, but be able to still change their mind until they let go - this lets them drag off of the object which will return

also update: it worked 🙂

[rich bluff]

this relies on ui space, even if you add threshold its not a tile or 3d space

[rancid tinsel]

what do you mean?

as in the IPointer interfaces?

[rancid tinsel]

im using them over getmouse.... because i dont want the player to be able to select towers etc while a UI component is in the way

[rich bluff]

it may break at specific angles scenarios because you are working in 2d ui space

[radiant frigate]

probability is an array, and if an item exceeds the price i want to remove all the numbers assigned to that item in the array (which i cant since its an array) so i should convert it to a list, but then how can i delete, for example all "2" inside the list ? and is there a way to make a list contain all that an array has?
Example:
private int [] probability = {1, 1, 1, 1, 1, 1, 1, 1, 2, 2, etc etc
list<int> numbers = new list <int>();
numbers.add(probability);
or smth like that?

[rich bluff]

those interfaces are great at that, true and i might be misunderstanding your setup

[wintry quarry]

AddRange or simply new List<int>(theArray)

[dawn kestrel]

is there a way I can highlight a point in the world given a Vector3 for debugging purposes?

[rancid tinsel]

one issue with the way i did it though is that the position has to be exactly the same, so if the player moves the mouse a bit while still hovering the object it wont work 😭

[wintry quarry]

Gizmos

[radiant frigate]

ill try ty!

[dawn kestrel]

I tried and failed this. Is there a way to make it really bloody obvious?

[rich bluff]

the object is a collider with IPointer interfaces, so just add IPointerEnter/Exit to notify you of hovered state

[wintry quarry]

Look up the docs for OnDrawGizmos and Gizmos.DrawSphere. also don't forget to turn gizmos ON in the scene and game views

[rich bluff]

and only abort if not hovered

[rancid tinsel]

you are a genius

i can actually simplify is even further since im using the Enter and Exit for color changing already

so i can just compare the color

thank you!

[radiant frigate]

is there something for lists that gets the lenght? like in arrays: "whateverTheArrayIsCalled".lenght;

[rich bluff]

.Count

[radiant frigate]

that gives me a group of methods and i need it as a float

[rich bluff]

post code

[radiant frigate]

wait i think i know where i f up

nope i dont

the error says: you cant convert "group of methods" to "float"

[rich bluff]

what type is enemyType what type is probability

[radiant frigate]

i messed up the probability name

im an idiot

it was supposed to be numbers

it was an array

and it should have been a list

[wintry quarry]

Even when you do it correctly it's going to be an int, not a float

[radiant frigate]

i dont know why but afterwards the error didnt show up

[wintry quarry]

Afterwards what

What error were you expecting

[dawn kestrel]

how do I get a gizmo to fire just once after using a method?

[wintry quarry]

Random.Range with two ints is a thing, and perfectly valid

[dawn kestrel]

wait, I see them!

[radiant frigate]

oh now i understand what you mean

[radiant frigate]

i was reading an error that said that

[radiant frigate]

the one on here

[radiant frigate]

i wasnt expecting an error but when you said it still wasnt a float i meant that the error wasnt showing up at that time

[rich bluff]

I found that using a single "gizmo manager" is convenient for that

you make a class that you can send requests to

[dawn kestrel]

huh, I wonder why they are so off from where they were supposed to be

[rich bluff]

like draw box for 5 frames with this color

[dawn kestrel]

for reference, those red and yellow boxes are supposed to be at the ends of the capsule collider

[rich bluff]

you can draw gizmos in local space btw

Gizmos.matrix = transform.localToWorldMatrix

then you can use your capsule end points as just offsets

[dawn kestrel]

but they're drawn at the end points of my CheckCapsule method

            Gizmos.DrawWireCube(end, new Vector3(10, 10, 10));

or start.y , whichever axis is "up" on the capsule

So, I'm trying to create the end game stats to appear when the timer hits 0, but when the timer hits 0, nothing appears to happen. Anyone know why? https://hastebin.com/share/neyonotugo.csharp

[wintry quarry]

Starting with some log statements would be a good first step

[rich bluff]

what is Timer ?

[topaz thistle]

A script

The time does go below 0, I used a log statement for that

[rich bluff]

this can take a long time to debug, or you can use debugger to step through line by line and see where it fails

[topaz thistle]

But I'm not sure what else to do

[wintry quarry]

Use logs in THIS script to make sure the code you expect to be running is running

[topaz thistle]

All I can think of for a log statement would be the time. Would u be able to suggest some others?

[wintry quarry]

Yes, put a log inside that if statement and that function

To make sure they're actually running

[topaz thistle]

Ok

[wintry quarry]

Basic stuff. Question your assumptions

Make sure there's no errors as well of course..

[topaz thistle]

Yeah, there isn't :D.

[rich bluff]

ever used debugger?

[topaz thistle]

No?..

[rich bluff]

good time to start

[topaz thistle]

K xD

[desert flume]

how to access components and game objects from scripts without having the variable public

[wintry quarry]

SerializeField can serialize private variables

If you mean "without assigning in the inspector at all", then you have to get a reference some other way

[rich bluff]

https://unity.huh.how/references

[desert flume]

Are there any bad practices that beginners would do that I would want to know?

[wintry quarry]

Sure, public variables are one

There's hundreds

[topaz thistle]

No idea why, but this time the script worked? Debug.Log scripts are just fixers I guess

[wintry quarry]

Maybe you forgot to save your changes earlier

[desert flume]

can you get any off the top of your head?

[wintry quarry]

Too lazy

[topaz thistle]

I'm sure I did... Anyways, thanks for you help

[rich bluff]

spamming singletons instead of a single simple service locator

[desert flume]

fair

[rich bluff]

relying on very specific paths, or tags in hierarchy instead of using interfaces or marker components to locate objects

[desert flume]

how would you use interfaces to locate objects?

and what are marker components?

[rich bluff]

GetComponent<IMyInterface>()

[desert flume]

Ah

but the interface wouldnt be yours

it would be a unity component interface

[rich bluff]

marker component is just a dummy component, empty

what

[desert flume]

e.g getComponent<TextMeshProUGUI>

since how would a component implement your own interface

[rich bluff]

im talking about your code

the only you can have any interface you want

[desert flume]

Not sure I get it, do you have anything I can read?

[north kiln]

https://unity.huh.how/references/getcomponent-methods#use-with-interfaces

[rich bluff]

from experience, a character rig, with bunch of hitboxes, mount points, etc

context for what im talking about

[desert flume]

how would I give IDamageable to a game object?

just have a script implement it?

[rich bluff]

yes

[native seal]

public class DamageTrigger : MonoBehaviour, IDamagable

[desert flume]

Yeah I get it

[native seal]

so then u can have some external thing access it through IDamagable instead of a direct reference to your class

[dawn kestrel]

alright, I got it this far! Thank you!

[north kiln]

Presumably a player or a damagable box or something would implement that one

[native seal]

interfaces are used to implement a feature shared between many things but have very different implementations

[desert flume]

this wasn't possible in java until java 17 😭

[native seal]

it doesnt make much sense to have a interface on a generic "DamageTrigger"

unless thats for your player or something specific

[north kiln]

Hence why it didn't have the interface

[native seal]

ah i thought he wanted to know how to implement the interface on his class

didnt realize my fault

[north kiln]

I'll be updating my doc to be clear about the usage example 👍

[dawn kestrel]

oh goddammit. Do you know what my issue ended up being? I read this backwards.
layermask: A Layer mask that is used to selectively ignore colliders when casting a capsule.
"Layermask" is actually a parameter for what layers not to ignore.

Hi all, would someone be able to check my maths on this bit of code please?

I'm trying to come up with a Long/Lat system and it's going pretty well. The Longitude calculation works fine, but my Lat calculation NaN's out almost immediately when I move and I'm not really sure where I've gone wrong.

void Update()
{
    RaycastHit hit;
    // Does the ray intersect the Moon's inner collider?
    if (Physics.Raycast(eagleGPSRayEmitter.position, eagleGPSRayEmitter.TransformDirection(-Vector3.up), out hit, Mathf.Infinity, layerMask))
    {
        eaglePosX = hit.point.x;
        eaglePosY = hit.point.y;
        eaglePosZ = hit.point.z;
        //Debug.Log("Hitting inner Collider");
    }

    longitude = (Mathf.Atan2(eaglePosZ, eaglePosX) * Mathf.Rad2Deg)-90f;
    latitude = (float)Mathf.Acos(eaglePosY) * Mathf.Rad2Deg;

    // this bit is to flip and quarter rotate the latitude number to put it where you would expect
    // (assuming you are an earthling)
    // with 0 at the equator, 90 at the north pole and -90 at the south pole
    latitude = (latitude - 90f) * -1f;

im getting an error that tells me that an index was out of range, i have went through the code and couldnt find why or how its happening.
https://gdl.space/esevorayuh.cs from lines 54 to 84 is the code that should be relevant and the error shown in the video is in line 56

[ruby python]

Try debugging your list to check how many values are in there when you've assigned 'probability'

[rich bluff]

i dont see how this can fail only when you start moving

only possibility is that the raycast somehow returns 0 y

or some other crazy number resulting in infinity

try using debugger to see what exactly happens

[thorn tapir]

which direction should I be moving the center in when crouching/uncrouching? Right now it seems like no matter what I do, the controller is pushing against the ground while the height is lerped which causes me to slide down slopes and stairs.

[ruby python]

It definitely doesn't return Zero, the value does change based on movement, but nans pretty much straight away. This is way more complicate maths than I'm used to if honest. lol.

[rich bluff]

first establish exclude that its a faulty raycast

faulty can mean it stops at some other collider, inside the collider or something else similar

[ruby python]

Raycast debug....

Values are 'moving' as expected.

[teal viper]

Assuming unity Mathf.Acos is wrapping the C# one, it would return NaN if the the input value is invalid(< -1 or > 1) it seems.
https://learn.microsoft.com/en-us/dotnet/api/system.mathf.acos?view=net-8.0

[rich bluff]

        public static float Acos(float f)
        {
            return (float)Math.Acos((double)f);
        }

yep

[ruby python]

Ah crap. 😕

[teal viper]

This could happen if the numbers list doesn't contain any elements. It would try to access index 0 which doesn't exist.

[radiant frigate]

but i reset the list content after the while for that same motive

[vale cradle]

guys i am working on my enemy and he is supposed to shoot fireballs when the player is in range but when i enter the enemy range it doesn't shoot fireballs and i get this error i am not able to understand where i went wrong even my code has no errors

[ruby python]

Debug you list to see what's actually in there?

[radiant frigate]

omw

[ruby python]

You're missing an assignment in the inspector by the looks of it.

Or 2.

[vale cradle]

i don't understand

am i supposed to change the player layer to enemy?

[ruby python]

Your variables enemy and anim are unassigned (Unity can't find them) in your EnemyPatrol script. How are you assigning them?

[rich bluff]

@vale cradle in your project panel, type into search t:RangedEnemy

[vale cradle]

okay

[rich bluff]

and check every instance for missing references

not project

[ruby python]

Guessing enemy is a gameobject and anim is your animation controller?

[rich bluff]

Hierarchy

[vale cradle]

i'll paste my code here?

[rich bluff]

it says enemy patrol is not assigned

[vale cradle]

yes

[rich bluff]

i dont see enemy patrol in that screenshot, im assuming its another component

[vale cradle]

just a min

[teal viper]

I don't see how resetting is gonna help? If anything, that's probably the cause

[vale cradle]

i got where i missed it i didn't assign it to the animator

i got it

thankyou so much guys

[radiant frigate]

that makes the list reset in case the engine tried to buy something it couldnt afford and therefore got removed from the list, which will be usefull for the next wave

[teal viper]

Ok, but that doesn't change the cause of the issue as I described several messages earlier

[radiant frigate]

wouldnt it answer this?

[cloud shore]

numbers array at [Random.Range(0, numbers.Count)] does sometimes not exist...basically

[teal viper]

No it doesn't. As I said, it's probably the cause.
Imagine you have 0 apples.
And then you try to pick the first apple that you have. What would happen?

[radiant frigate]

but how is there a moment where it doesnt exist?

[radiant frigate]

but i always have apples

[teal viper]

Apparently not. That's the only case that error would be thrown

[radiant frigate]

yep apparrently not and thats what i dont get

since i have done the math so that doesnt happen

[teal viper]

Well, debug it. Where are you clearing the list or removing stuff from it?

[radiant frigate]

oh nvm i got it

i think i know where it is

[ruby python]

Hmmm. Would anyone have any clues as to how to fix my latitude issue please? Giving me a headache. lol.

[radiant frigate]

i think its because the maxType gets reduced b4 the foreach

so it starts deleting the "1" inside the list

and since 1 is the lowest thing it cant afford anything and the error jumps

[rich bluff]

that should not even work

[teal viper]

Debug it... So far these are just assumptions(that don't even make sense to me too)

[rich bluff]

my bad it should

[radiant frigate]

xD

[rich bluff]

you cant modify collection while foreaching it, but you are removing from a different one

you should learn to use debugger

it will solve a lot of issues

[cloud shore]

what happens if you do....an error or what exactly?

[radiant frigate]

i have debuged some things but idk how to debug this

[rich bluff]

exception

[radiant frigate]

its just an int

[minor patio]

Shenanigans! Shenanigans!
I've got a method attached to a button that is for some reason executing twice...

[teal viper]

print

[teal viper]

Print the int

[radiant frigate]

so just debug.log(int)?

well maxType instead of int

[rich bluff]

yes or learn to use the debugger

[teal viper]

Might want to add some meaningful message to it too

[minor patio]

yup - debugger is essential, and I'm only just getting used to it

[radiant frigate]

debug.log("maxType" + maxType);

that?

[cloud shore]

you have to understand it...if this workds for you

[teal viper]

I don't see how maxType is related to the issue though..?

[radiant frigate]

yeah my code is a bit spaguetti rn

but max type tells the game what probability to "erase"

there are 2 qualitys at the moment

[teal viper]

THe problem is not that a specific element is erased. But that all of them are erased

[cloud shore]

Despite using the debugger you also should do more logs and better logs, for understanding problems

[radiant frigate]

if the engine cant afford quality 2(which costs 5) it will remove 1 from maxType

[radiant frigate]

wait let me finish and you will understand the problem that i had/im having

[cloud shore]

this a help request xD?

[teal viper]

Whatever logic you have doesn't matter. The issue is that the list is empty at some point. You need to debug where and why it's becoming empty. Assuming that's undesired behavior

[minor patio]

... it might be - I'm in over my head; but I have had similar issues before & I've managed (somehow)

[radiant frigate]

so in the foreach it removes each int = to maxType,
since i was doing Maxtype -= 1; before , the maxType dropped to 1 b4 entering the foreach cycle, which led to all "1" getting deleted and therefore being empty and making the game unable to choose a 1 from the list

[cloud shore]

so you did make sure that the method is not called by any other script or elsewhere, just the button?

[radiant frigate]

so now that i moved it from b4 the foreach to after it it should work fine

[minor patio]

I'm just thinking out loud about how a method might inadvertenly be triggered twice by one button interaction - I do have it rigged with an interface that's very one-sided...

[radiant frigate]

which i just tried and doesnt

[teal viper]

Then your assumption was just wrong

[radiant frigate]

yep

[teal viper]

You should debug properly

[radiant frigate]

how can i do that?

im reading the debug and i dont understand what happens

[teal viper]

Wherever you remove elements from the list, debug the count of the elements in the list

[cloud shore]

log everything everytime, so you can understand what happens

[radiant frigate]

so inside the foreach?

[teal viper]

Is that where you remove stuff from it?

[radiant frigate]

yep

[teal viper]

Then yes

[minor patio]

heh - deleting the interface didn't help
but it also didn't hurt 🙂

[cloud shore]

you also might want take a look at the debugger...note: debugger != debug.log

[radiant frigate]

alright ill do once i finish with this

[radiant frigate]

okay so what is happening is that once it beggins to delete an int from the list it just erases all of them

[teal viper]

Sounds like a problem

[radiant frigate]

yep

[rustic epoch]

I have a lil problem, could somebody help me ?

[teal viper]

Would need to debug why that happens. Or read the code and infer from it.

[cloud shore]

everyone here, just ask😁

[minor patio]

(bites lip) >:)

[radiant frigate]

what i am doing is that for each "maxType" (which starts at 2) inside an array called probability, it erases from the list numbers one "maxType"( a 2 )

or atleast that is my intention

[rustic epoch]

I have a code that is supposed to allow the player to move arround and move the camera as well, but it just moves the camera in one way, dont know why.

[minor patio]

"numbers.RemoveAt(i(maxType)); ...?

[teal viper]

then probability contains the same elements as numbers causing erasing all the elements from numbers.

[rustic epoch]

I cant share the code it's too long

[teal viper]

Remove will remove all the maxType entries found

[radiant frigate]

probability has two 2´s

so it should erase the other two 2´s from numbers

[teal viper]

Then numbers contains two 2's as well

[minor patio]

coz you've got it in a foreach

[radiant frigate]

yes

[teal viper]

And that's it

[rustic epoch]

https://gdl.space/fehefaziju.cs

[radiant frigate]

yeah but once they are deleted maxType changes to -= 1 so it becomes a 1

and shouldnt try to delete more 2´s

[minor patio]

where do I find this quick-link?

[teal viper]

No..? At least not in the loop

[radiant frigate]

just below

[teal viper]

Where? I don't see that in the loop

[radiant frigate]

its under the loop

[teal viper]

Why would it matter after the loop? Do you understand how code is executed on computers?

[radiant frigate]

i think i do

which seems to not be the case

[teal viper]

So, why would it matter what it becomes after the fact? Also, the maxType in the loop is a different variable

[rustic epoch]

ok, it justed worked after 2 days... I did'nt changed anything...

[minor patio]

gremlins on long-service leave...

[teal viper]

Don't you see that they have different color?

[radiant frigate]

and how can i make it the same

[radiant frigate]

yeah i just noticed when you told they are not the same

[teal viper]

1. don't declare a local one
2. that wouldn't fix the issue

[rustic epoch]

yea xD

[radiant frigate]

so i just delete the "int"?

it gives me an error if i do so

[teal viper]

Yes, obviously that would make the loop syntax invalid

[radiant frigate]

then how can i tell it to be the other maxType?

[teal viper]

Maybe think again what you're trying to do. Why would you want to use max type in a for each loop?

[radiant frigate]

foreach max type (which is 2) in probability

[teal viper]

for each is giving you values from the collection. If you're not using them, there's no point in it

[radiant frigate]

so for each 2 i have in probability it should repeat the code

[teal viper]

Then maybe you should use a for loop instead? Since it doesn't seem like you need whatever is in the probability array/list.

[radiant frigate]

i just have the probability array so in each end of a round i can make the numbers list = new list <Int>(probability);

[teal viper]

That doesn't tell me anything.

[radiant frigate]

im thinking of how i could do it

[teal viper]

I'm sorry, but I really don't understand what you're trying to do. Not from a coding perspective, but from pure logic perspective.

Maybe write your logic down on paper(in the form of a blockscheme for example)

[radiant frigate]

that whenever it cant afford an item erase it from the list so next time it tries to buy something the items it cant buy dont exist

i used a for instead of a foreach and it worked

i dont know why tho

[teal viper]

then it would look something like this, no..?

if(can't afford item)
  remove from list(item)

[radiant frigate]

yes

but since i also have it done as a probability

[teal viper]

Then I don't understand what probablilities and other stuff has to do with anything

[radiant frigate]

i have more than one 1 and more than two 2

[teal viper]

I don't understand

[radiant frigate]

okay wait im going to try to explain everything

the engine has an amount of money

15 for example

each item has a price depending on quality:
q1 = 1$
q2 = 5$

so it chooses it random, but since i want that the higuer the quality the less chance there is to get it,

i have it choose from a random.range between 0 and the max amount of a list

lets say eight amounts of 1´s and two 2´s

so its 80% and 20%

once it decides which item to buy

lets say 1 q2

the money gets set to 10 since the price is 5

it chooses again

and its another q2

5 coins remaining

now its a q1

we have 4 coins

if the engine decides to buy a q2

for each 2 in probability it should erase one two in numbers

therefore the next time it tries to buy it it cant since there is no 2 in numbers

and can only buy q1 item

i think that summarizes it well

[teal viper]

That sounds super convoluted and prone to bugs to me.

[radiant frigate]

after that i reduce the maxType -= 1 so the next quality it should remove in case it can not buy it is q1

but that is for future enemies since i now only have 2 and the q1 is 1 coin so it is always affordable

[radiant frigate]

i didnt think of a better way of doing it

[teal viper]

For starters, it sounds like several independent systems are mixed together.

[radiant frigate]

it was the form that i came up with that was inside my knowledge

[teal viper]

One that should be selecting items randomly and one that maintains the list of available items?

[native seal]

digital when doing things like this do each step seperately

[radiant frigate]

i started doing each thing once at a time

[native seal]

for example in my game, item drops are rolled first by deciding if it should even drop, then deciding the amount to drop, then deciding if it should upgrade the rarity, then rolling the modifiers based on everything before

[radiant frigate]

by deciding an amount ?

[native seal]

fixed it

[radiant frigate]

yeah i had something like that

[radiant frigate]

but since its not an actual shop it doesnt fit what i need

[queen yoke]

this scritp i write for +1 increment why when i hit to 3 time and hit 4th it's back to count 1

what im i wrong or missing?

[radiant frigate]

my game is a wave survival and what goes shopping is the engine for random waves of enemies, so it cant be once x quality and x amount and the next just 1 amount and from quality1 since it would be unbalanced

so i assign a price to each enemy and give money to the engine to go shopping

[native seal]

im confused as to what you want to achieve

[radiant frigate]

so it doesnt matter the combination it always has the same amount of "goldvalue"

to balance out each wave

so it wont happen that in the first round you get 4 q2 enemies and the next 2 q1

[queen yoke]

i want to kick on football hit the goal

then +1 for each hit the goal

everything ok but when it cout 1 2 3 on hit no. 4 it count 1 again

[native seal]

i was talking to digital sorry

[native seal]

what is 4 q2 and 2 q1

[radiant frigate]

i went through the code but i dont know what is happening

[radiant frigate]

4 amount of quality 2 enemies

and 2 amount of quality 1

[native seal]

you are probabaly changing scoreGoal from somewhere else, there is no reason for it to be public

[queen yoke]

i have many goal the same script

[native seal]

so you want to pick a random amount of enemies that add up to 15 quality?

[mint mirage]

help, I wrote the same things in what was shown in Brackey's video but I keep getting an error

[radiant frigate]

not to 15 quality but to 15 coins, and each quality has a price assigned

q2 enemies have a 5 coins value

and q1 have a 1 coin value

[queen yoke]

ball hit throug many goal

[native seal]

so it could spawn 15 q1 or 3 q2 or 2 q2 5 q1

for example?

[radiant frigate]

yes

[native seal]

just roll an amount of q2 then assign the remaining to q1

or roll q3, then roll q2, then assign rest to q1

to add up to whatever amount you want

[radiant frigate]

but when i roll q3 i dont want there to be more q3 than q2 or q1

so with the probability system i add that factor

[native seal]

ok then roll only up to half of the gold value

[minor patio]

no ;

[radiant frigate]

makes completely sense

[minor patio]

better

[radiant frigate]

but i also want there to be a possibility to be just q3 for example

[native seal]

ok then just do random rolls like i said

[mint mirage]

the monobehaviour isnt orange and the Transform and Debug aren't either

is that a problem?

[minor patio]

MonoBehaviour requires using System;

[gaunt ice]

you want a sum of value of coins dropped from enemy is some given number?

you need backtracking in this case

[native seal]

no it doesn't

[mint mirage]

but in Brackey's vid he deleted them

[native seal]

it needs UnityEngine only

[minor patio]

my bad - I knew it needed something

[native seal]

system is the c# library

monobehavior is a unity only class

[radiant frigate]

but i want a balance between probability quality and amount

[native seal]

make a function then

[radiant frigate]

that does what?

[native seal]

that has a curve based on some input x

go on desmos to mess around, thats what I do

[minor patio]

anyone care to take a stab at why my code would be finding an object twice?

[native seal]

wdym?

[minor patio]

& no - it's not being called elsewhere

it's attached to a button, & it gets an object from the button's parent title field...

[native seal]

post code man

[minor patio]

where's hastebin?

[radiant frigate]

idk what that is im not that advanced on coding

[native seal]

its not code, its just math

if you've done algebra in high school it should be simple to you

[radiant frigate]

but since i managed to do a system on which i have been working for 2 days i wanna take a rest and do something else like a new enemy or something like that

i have done algebra but the level of the school where i went was honestly shit so i didnt really learn much

[native seal]

how do you want this balanced?

in what way

that would be how you define your function

[radiant frigate]

ohhh

idk if there is a function for that

but i want there to be a possibility where all are high quality enemies,(just unlikely to happen)

maybe 1 quality 5 enemie and 3 q1

[native seal]

function as in f(x) = mx + b

you would define your own

[radiant frigate]

yes i know but i dont know if i have the ability to do so

kewk

what is f(x) = mx + b?

[native seal]

okay well then there wont be some magical way to weight your results

[radiant frigate]

is it just a normal equation?

f(x) remembers me of graphs

[native seal]

it would be however you define your curve

yes

[minor patio]

isn't that base notation for fractals?

[native seal]

functions can be mapped to a graph using x,y coordinates

[radiant frigate]

srry i didnt pay that much attention in math class

[minor patio]

close to

[radiant frigate]

tbh in no class

[native seal]

that is point intercept form, nothing to do with fractals

[minor patio]

ouch

[radiant frigate]

i dont know how to create functions it seems

[native seal]

for example, this is my function to determine the quantity of loot dropped

[minor patio]

now you too can create a function!

[minor patio]

it does look elegant

[native seal]

lol, it need to fix it though, right now enemies drop way to much loot

[minor patio]

I always was greedy :))

[radiant frigate]

so just a normal algebra equation?

[carmine elbow]

is using Transform.Find() a bad habit? as it's basically hard coding and prone to failure if mistyped?

[native seal]

yes

[minor patio]

how do I find the pastebin/hastebin links?

[radiant frigate]

f(x) = mb + b scared me

xD

[native seal]

so this is my function mapped to a graph where the x-axis corresponds to the monsters level and G is the loot bonus based on the rairty (500 is boss for example)

you could do something similar to weight your output based on multiple parameters

[radiant frigate]

yes but it is not directed only by two factors

[native seal]

haha, they drop about 500 items right now, too laggy

[radiant frigate]

it has to include the amount of money currently the quality of the enemies the previously bought enemies and what qualities they were how much probable it is to choose 1 enemy etc etc

and to be honest i dont to involve myself in that now

since this isnt a definitive game but just a learning one

[native seal]

i dont see why it even needs to be that complex at all

but that would be possible

just use more parameters

in your function

but if you were to graph it, you would make x be whatever value you want to see on the x-axis unless you want to go into 3d planes lol

other parameters you can define like I did G

[radiant frigate]

yeah seems like that is what my thing would point into

you seem pretty chill

can i add you ?

[native seal]

sure, but no haha you would only go into higher dimensions if you want to visualize more than 1 value changing

[radiant frigate]

i want to see the amount of enemies and the quality of them change

so ig it would be 3rd dimensional?

[native seal]

i don't think you're understanding what im saying

[radiant frigate]

it seems like im not

[native seal]

when you graph something on a 2d plane, you are visualizing the relationship between x, your input, and y, your output

you can define more parameters, but they would have to be defined like I did G and be changed manually

since any more variables would create more dimensions

its just for visualizing

nothing else

dont let it confuse you

[radiant frigate]

im dumb i thought you were calling me G BHAHAHAHAHAHA H

[native seal]

lol

just refer to the screenshot

[radiant frigate]

yeye ik

[native seal]

what would your parameters be and what would be your singular output

then think about how much you want each parameter to affect the output

[radiant frigate]

i want more than 1 output i think

[native seal]

that doesn't make sense

your output should be the quantity of the enemy

no?

[radiant frigate]

imma talk about that with a friend that graduated something related to maths so he can explain it further and for people as dumb as me

[radiant frigate]

and the quality

[native seal]

your quality would be an input since you want to have enemies for each quality

then your function would take the quality and reduce the output if the quality is higher

in relation to your other parameters

[radiant frigate]

yes but i want there to be more than 1 enemy per thing

srry i think im dumb

xD

maybe im just not understanding it for some reason

[native seal]

you're fine but what do you mean more than one enemy per thing

f(enemy quality, total gold amount) -> some amount of that enemy to spawn

yes?

[radiant frigate]

kind off but i want the quality to be random

with a lower chance of happening

but in case it decides to do a lot of high q enemies it will produce less since the gold can only afford that much

[native seal]

so just assign weights to each quality

and for each enemy spawned, loop through the weights and assign the highest enemy that rolled true

[radiant frigate]

srry but my brainpower is kinda off

[native seal]

this is my code that loops through several stat tiers and chooses the highest tier than rolled true

[radiant frigate]

i would love to understand it but i have been programming for 11 hours straight with no break for either water or food and im just completely empty rn

[native seal]

fair lol

[radiant frigate]

imma try to guess how it works tho

i love math

its fun

[native seal]

indeed

[radiant frigate]

i hated a specific part of maths but i cant remember

[radiant frigate]

on the first part wouldnt //default to the lowest tier [9]

be "the higuest

or do you have an inverted system?

[native seal]

tier 0 is the best while tier 9 is the worst

so it starts as the worst tier

[radiant frigate]

where quality 1/0 is the best

[native seal]

then rolls all the tiers

[radiant frigate]

ohhhhhh

yeah now it makes more sense
